Ett skogsbruk anpassat för tjäder : med fokus på häckningsframgången
I detta kandidatarbete har de viktigaste faktorerna för tjäderns habitatkrav ringats in via litteraturstudier. Därefter har ett skötselprogram utformats i planeringsprogrammet Heureka ? PlanVis, där dessa inkorporerats.
Litteraturstudien mynnade ut i att flaskhalsen för en tjäderpopulations existens till stor del ligger hos tjäderhönan och hennes häckningsframgång. Framförallt två kritiska faktorer träder fram, nämligen skydd mot predation och föda. Genom att identifiera hur dessa faktorer ter sig i skogen kunde de befordras i utformningen av skötselprogrammet.
Skötselprogrammet är framtaget med området Strömsjöliden som underliggande data.
Lyssna på mig! : Barn & ungdomar med funktionsnedsättningar vill vara delaktiga i möten med samhällets stödsystem
Children?s participation in their planning in health and social services is important. To make children?s needs more considered they need to be involved in the cision-making processes. Children have the ability to reflect.
Rovdjursproblematik i Sverige med fokus på varg och får. Vilka lösningar finns?
The Swedish wolf population is like continue to grow and this will eventually lead to an increase in the predation of livestock. In Sweden carnivore attacks happen most frequent on sheep farms and the majority of these attacks are performed by wolves. Because of this, the main focus in this study is on the sheep and wolf problematic.
It is not only the direct killing of livestock that affects the animals and their owners in a negative way. It has also been shown that livestock that lives close to carnivores sometimes change their behaviour in a way that will affect their ability to reproduce and to forage efficiently.
Förebyggande arbete mot våld och hot om våld inom socialtjänsten : En kartläggning av chefers upplevelser
Dealing with threats and violence at the workplace is a reality for many social workers, where a majority of them have to face client oriented incidents at least once during their career. Incidents are most commonly expressed as threats and harassments, but can also take place in the form of physical violence. Looking at the problem from a supervisor perspective, it will affect and possibly damage the specific exposed employee, the workplace as a whole and the clients. Supervisors are the ones responsible for developing workplace enviroments that are satisfyingly safe, for which guidelines can be found in law as well as in an emerging research area. Reasons as to why some people tend to become violent is as complex as reasons as to why some people seem to be more vulnerable or exposed than others. That is why means of preventing threats and violence can not be explained in one single way, but the answer must be sought on several levels.
Arbetsminneskapacitet: relation till verbalt flöde och indirekt minne för inhiberat material
Processing information in complex everyday life recruites different abilities than limited storage capacity. Working memory, the central executive and inhibition are constructs that have been used to describe this ability of adaptation. This paper investigates the connection between working memory capacity and performances in tasks closely associated to real life situations, i. e. verbal fluency tasks.
Metodutveckling för analys av serglycinuttrycket i blodet hos hundar :
The development of quantitative, real-time PCR (qPCR) combined with the mapping of the canine genome opens new possibilities in veterinary medicine. This method provides a quick and accurate quantification of the expression of a specific gene at a given point in time and thereby also information of how the gene expression for a certain protein is influenced by various conditions and diseases. One possible area of application is identifying bio markers for cancer. Recently the protein serglycin (the core protein of an intracellular proteoglycan) was found to act as a selective marker for the disease acute myeloid leukemia in humans (Niemann et al, 2007). Serglycin is produced by most hematopoietic cells, although mast cells account for the largest amount of serglycin.
En tyst utmaning - några pedagogers erfarenhet av att arbeta med barn som har selektiv mutism
Selektiv mutism är en störning som försämrar prestationsförmågan i studier eller arbete samt försvårar kommunikationen. Störningen gör att barnet oftast avstår att tala på förskolan, sexårsverksamheten samt på skolan medan det däremot talar helt obehindrat hemma. Syftet var att få en ökad förståelse för hur några pedagogers arbete påverkas av vilken kunskap de har om och hur de arbetar med elever som har selektiv mutism. Undersökningen har genomförts utifrån fyra kvalitativa intervjuer med pedagoger som arbetar i tre olika kommuner i Sverige. Urvalet har gjorts utifrån deras erfarenheter av att arbeta med barn som har selektiv mutism och deras tillgång alternativt avsaknad av handledning i ämnet.
Renen och nötkreaturet, en jämförelse mellan två olika typer av idisslare :
The aim of this literature review was to make a comparison between the feeding requirements of Swedish reindeer (Rangifer tarandus tarandus) and meat producing cattle (Bos taurus) within farming. Reindeer are an intermediate feeding type; they have the ability to adapt to short term seasonal changes in food. They avoid eating fibre as much as possible and display highly selective behaviour while foraging. Adaptation to harsh environments with a limited amount of food has made reindeer dependent upon easily digestible food and consequently their digestive systems are less capable of processing plants with high fibre content. Herding is an extensive system which requires a significant amount of land and labour and describes the reindeer industry.
Självmord : en kunskapsöversikt
The aim of this essay is to try to gain understanding and to get a more profound knowledge of suicide. The questions at issue were 1) What empirical factors are mentioned in the research as possible to explain suicide. 2) Which theoretical perspectives are discussed in research concerning suicide. To answer our questions at issue we carried out a selective research overview with a qualitative perspective. The primary documents that has been the foundation of this essay is constituted by nine of the leading researchers publications in the area of suicidology.
Kan ett tillskott av tryptofan ha en inverkan på sjukdomstillstånd som depression och/eller smärta?
5-hydroxytryptamin (5-HT) is biochemically derived from Tryptophan. Kynurenic acid and quinolinic acid are also known metabolites of tryptophan. 5-HT is considered to play a role in depression and today selective serotonin reuptake inhibitors (SSRIs) are used for treatment of depression. 5-HT may also play a role in pain perception. The aim of this study was to investigate whether a supplement of tryptophan may affect conditions such as depression and/or pain.
Trådlös kamerastyrning
As an amateur it can be difficult filming from several angles at the same time as this requires several cameras. It´s also hard to film at occasions when it´s not appropriate to manoeuvre the camera manually. Systems for solving these problems already exist, but it´s either more expensive, professionalsystems or cheaper systems with limited functionality.The purpose of this project is to develop a cost efficient solution to the problem above that offers a better functionality then existing commercial systems. The biggest difference from existing products is the wireless video feedback from the camera to the remote unit.The result of the project is a system consisting of two units, a manoeuvre unit with a cradle for the video camera and a remote unit from which the operator can control pan and tilt of the video camera.Communication between the two units is wireless.On the remote unit there is a joystick and a display mounted. In addition to this, there is also an IR receiver that is capable of reading the signal from the cameras own remote and sending it to the manoeuvre unit.The manoeuvre unit is equipped with one motor to control the tilt function and one motor to control the pan.
Oönskade Döttrar - Traditionella mönster i ett modernt samhälle
Due to traditional beliefs about biological differences between the sexes, the sex ratio is abnormally uneven in northern parts of India. There is a combination of old methods like female infanticide and new technologies, which make selective abortion possible. The strong practices of dowry transform daughters to economical burdens to their parents. They face mortal danger before, at and after birth. With rapid economical progress and advanced technology, India is a country in progress.
Barnfattigdom i Sverige, finns den? : En studie om Socialdemokraternas och Moderaternas välfärdspolitik mot den svenska fattigdomen sedan 1960-talet
This essay is regarding the problematic facts about child poverty in Sweden. Since the beginning of the new millennium child poverty has increased, in Sweden. The last report which came out in the spring this year (2012) opened up for a lively political debate as well as big headlines in news papers and other media. The attention it got in Society became hard for the politicians to avoid. The Swedish section of Save the Children, demanded in their report concerning child poverty in Sweden that the Swedish Government need to do an inquiry about the increasing child poverty. Today in Sweden, there are two big parties, and they have been the biggest for a long time now.
En jämförelse mellan får- och nötkreatursbetade hagmarker med avseende på populationsstorlek samt artsammansättning hos dagfjärilar och örter
Many of Europe?s day-living butterflies have shown decreasing populations during the last decades and many species are threatened. Many butterflies are dependent on managed semi-natural grasslands because of their richness in nectar sources and host plants for the butterfly larva. Swedish pastures are mostly managed through grazing. The number of cattle in Sweden have been decreasing while the number of sheep in the country increased by 30%.
Nyckeltal för älg och fodertillgång på tall Pinus sylvestris och rönn Sorbus aucuparia
It has been shown that moose can affect plant community composition and structure. Selective browsing with other damages of large herbivores on tree species with different tolerance to disturbance could reshape the tree layer in both managed and natural forests. Rowan Sorbus aucuparia is widely distributed throughout Sweden and Europe. Research has shown that browsing by moose may prevent rowan from reaching browsing safe heights. The goal has been formulated that, where rowan is indigenous, it should have a good competition status and be able to reach tree level.
