Alternativa skogsbruksmetoder i Norden : ett välbehövligt komplement?
Clearcutting systems have been the dominating silvicultural approach during the last decades in the Nordic countries. While economically rational, it is also leading to a trivialisation of the flora and fauna, and may result in negative reactions of people in urban settings. As a consequence of this, and a more diversified view on which goods and services forests should deliver, there is an increasing interest in broadening the range of silvicultural methods that are used.
The term continuous cover forestry (CCF) represents a suite of methods that have gained increasing interest in the Nordic countries. In CCF a considerable amount of the trees are left after harvest to favour values that require a continuity of tree-covered areas. There are thus hopes that this method will meet the needs for maintaining biodiversity and satisfy social and cultural values.
Foraging and anti-predation behavior of Thomson?s gazelles (Gazella thomsoni) and Grant?s gazelles (Gazella granti) at a waterhole
Prey species make behavioral decisions to reduce the perceived risk of predation and the time spent vulnerable to predation. Behavioral responses to predators are for example selection of specific habitat types and the presence of predators influence individual vigilance. Furthermore, there is a variation in feeding niches with different herbivores focusing their foraging effort on different vegetation types which is also expected to affect the choice of habitat. Behavioral data on anti-predation and foraging behavior at on waterhole is collected from Thomson?s and Grant?s gazelles at Ol Pejeta Conservancy (0°00?N, 36°56?E) located in semiarid bushed grassland in Laikipia district of central Kenya.
Traditionell ekologisk kunskap i en framtid med lokala, självförsörjande och urbana samhällen
Several scenarios point toward a future where we are far more people on Earth than today, where most of those people will live in cities and where oil no longer dominates in the transport systems and in agriculture as an energy source and where less energy will be available to us. The report investigates what areas in traditional ecological knowledge that can contribute to the transition that follows a future with less energy and establishes three areas with the potential of becoming important: areaspecific biological knowledge in societies that are more dependent upon its surrounding environment and its natural prerequisitesthe local management of these biological resources, which often means a fair sharing and sustainable handling of the resources and which has been observed in Nobel price awarded Elinor Ostrom?s researchthe world views that lie behind how the environment is considered and managed, world views that can inspire and point toward how we in the future should formulate world views that do not give the destructive modern management of the environment It is also noted that the magnitude of the city living in the future is a historical news and that very little research has been done in how traditional knowledge can be transferred into this kind of living..
KVARTERSINTEGRERING
Through the different stages of life people have different requirements for their homes. The requirements changes depending on people?s life situation, lifestyleand age. Depending on where people are in life they live in different place, often in areas with other people who are in the same stage of life. In Sweden, this separation has always been noticeable, sometimes more than other.
Landskapsarkitektstudentens utveckling : studium av Projekt 3
Landskapsarkitekt är ett yrke i tiden. Många människor har fått upp ögonen för detta spännande yrke och allt fler människor söker sig till landskappsarkitektutbildningen. Men när man frågar någon vad en landskapsarkitekt egentligen gör så väcks det fler frågor än svar. Detta beror nog till stor del på att arbetsområdet är så brett att det går att finna många olika nischer inom detta. Allmänheten tror för det mesta, på gott och ont, att en landskapsarkitekts arbetsuppgift till största delen består av att i dekorationssyfte pynta olika miljöer med vegetation.
Grönskans roll i framtidens stad : En stad i förändring
The aim of this study was to analyze the assessment of the primary school, from the teacher?s perspective. There has been an ongoing discussion regarding assessment and about the purposes of assessment for a long time. But there is a paucity of research on what teachers believe about. This study examined primary teachers? beliefs on major purposes of assessment.Assessment is the process of gathering and interpreting information about students? learning.
Förbättrat hörande, förbättat övane, förbättrat stridande : En analys av hur artificiellt ljud kan användas för att öka realismen vid stridsträning.
Saab Training Systems är ett företag i Saab-koncernen som utvecklar, tillverkar och marknadsför produkter för militär utbildning. Ett av de centrala systemen i företagets produktportfölj är det instrumenterade stridsträningskonceptet GAMER, i vilket soldater kan öva dubbelsidig träning samtidigt som övningsledningen via ett centralt styrsystem kan övervaka och interagera i övningsförloppet.I och med den övergång som skett i många av världens försvarsmakter, från ett tungt territorialförsvar till ett välutbildat insatsförsvar har kraven på den enskilda soldatens förmågor höjts avsevärt. Samtidigt har det även skett en övergång gällande den generella hotbilden, från att tidigare ha utgjorts av en annan militärmakt, till paramilitära grupperingar som ofta bedriver en gerillaliknande krigsföring. Dessa två faktorer innebär att även förutsättningarna för soldatutbildningen har förändrats.Som ett led i anpassningen till dessa förändringar utreds i denna rapport möjligheterna att utveckla soldaternas audiella upplevelse i GAMER. Detta för att skapa ökade förutsättningar för en komplett upplevelsebaserad inlärning, som inte bara övar soldatens förmåga att använda sig av den taktiska information som ljudbilden förmedlar, utan även förbereder soldaterna på bästa sätt för den främmande miljö som dagens militära insatser ofta innebär.Inledningsvis genomförs en ljudcentrerad användningsfallsanalys av en uppsättning grundläggande övningsscenarion.
Neutral bolagsskatt? : Analys om SOU 2014:40 skapar neutralitet mellan lånat och eget kapital
This paper examines the power producing dams along the Ume-river as an integral part of and a result from the urbanization process in Sweden during industrial capitalism. The aim of the paper is to contribute to the knowledge of the urbanization process in Sweden in general and of its traces along the Ume river in the county of Västerbotten in particular. The paper applies the theory of concentrated urbanization and extended urbanization put forward by Neil Brenner and Christian Schmid (2015) and argues that the building of power producing dams along the Ume-river is part of an extended urbanization process. This becomes particularly evident when examining the vast physical structures that is the dams, situated in an otherwise remote and sparsely populated area. These vast physical structures are also very well connected to a nation wide electric grid that has connections to bordering countries as well.
Nitrogen fixation among boreal feather mosses along a clear-cut chronosequence
The Swedish boreal forests are limited by nitrogen (N) availability. While biological N2 fixation by cyanobacteria hosted by pleurocarpous feather mosses are important sources of N input to natural boreal forest ecosystems, little is known about the patterns of N2 fixation in silvicultural systems. This study investigates the biological N2 fixation rates of two boreal feather moss species (Pleurozium schreberi and Hylocomium splendens) along a chronosequence from clear-cut to mature forest, as well as the vegetation characteristics along the chronosequence. Measurements and samples were collected from 32 forest sites that were classified into four age classes (clear-cut, pre-commercially thinned, thinned and mature forest). The sites were located near the city of Arvidsjaur in northern Sweden.
Jämförelse av metoder att mäta genetisk variation hos djurparksdjur
Integration policies have failed to make diversity into anything more than occupying the same physical space. People of different cultural background still do not share their lives to any real extent. Attempts made within planning and landscape architecture to catalyst the integration process have mainly been focused on structural measures, such as residential policies. As for outdoor environments, non-verbal casual encounters in the shape of crossing paths are assumed to lie at the heart of urban social integration.The aim of the thesis is to question this assumption and, as the thesis will show, there is literature supporting this aim. Looking at the works of Gordon Allport, Lewis Coser and some of their followers, I find intercultural contact to require more complex ways of interaction in order to reduce prejudice and to generate tolerance and understanding.
Murgröna - fasadförstörare eller -beskyddare : en studie i huruvida murgröna på fasader påverkar den relativa fuktigheten vid fasaden
Arbetet berör problematiken om hur fasadvegetation påverkar den relativa fuktigheten intill fasaden. Examensarbetet berör ett ämne som idag är väl debatterat men debatterna bygger i stor utsträckning på antagande och enskilda företeelse. Arbetet visar exempel på att det finns en allmänuppfattning om att murgröna försämrar konditionen på fasaden. I arbetet belyses även den litteratur som finns i ämnet idag. Litteraturen kompletteras även av studier och rapporter som är utförda inom området.
Examensarbetet fokuserar runt den huvudsakliga frågeställningen om den relativa fuktigheten skiljer sig vid fasader beklädda med murgröna jämnfört med de fasader som är fria från vegetation.
Från känsla till handling : Empatins betydelse för frivilligas engagemang
Since the late 50th century, the automobile has been normative in the Swedish society (Lundin 2008). This has led to an urban environment deeply characterized by the motor vehicle and its necessities, while other means of transportation, such as train and bicycle, have been ignored and put aside. However, over the past decades, a new trend has been seen in urban planning as a consequence of the increasing knowledge of the negative qualities caused by the car. As a result, the bicycle is seen as a conceivable transport mode.This thesis examines cycling on four issues:- Why is there a need of more cyclists? - How can the total number of cyclists as well as the number of satisfied cyclists increase? - Which factors affect the choice of transport mode? - Which factors affect the choice of route?The first two questions are discussed from a literature study that was conducted at the beginning of the thesis.
Jag föreställer en kvinna men jag framställer mig själv : En kvalitativ studie i hur kvinnor kommunicerar genom sina kläder
This thesis aims at examining factors that influence women?s choice of clothing. Focus lies on what women want to communicate with their clothes, how consumption is used as a means of expression, women?s attitude towards the clothing and the body image that media has created. Is there an underlying idea in a women?s choice of clothing and is she trying to express something specific? Why do women buy the clothes they do? The aim with this thesis is to identify if there is a difference between people from an urban area and those from a small town, as well what role the geographic difference plays in how fashion conscious you are or how you choose your clothes.

Skötsel av tätortsnära skog : en utvecklings- och skötselbeskrivning för Karnas backe i Hörby
Inom 100 meter öster om Hörbys tätortsområde ligger Karnas backe med omgivande betes- och skogslandskap. Karnas backe omfattar ca 30 ha och ägs av Hörby kommun med kultur och fritidsförvaltningen som huvudansvarig för tillsyn och skötsel av platsen. Området består av ek- och hassel dominerad blandlövskog med inslag av björk, al och asp. Inom området finns även en ohävdad gammal inägomark. Landskapet är kuperat, variationsrikt och tätortsnära och är därför ett värdefullt rekreation- och friluftsområde.
