Sociala mediers betydelse på dagens marknader : Företags vilja att förstå sina kunder

Title: The role of social media on today?s markets ? Companies? desire to understand theircustomersAuthors: Kristoffer Avci-Nåmark & Patrik WidlundBackground: The markets of today are characterized by dynamic conditions because of thecontinuous change in consumer preference. Due to this, the interaction between the company and its consumers is gaining importance as companies find the need to increase their knowledge about the market. Out of this need social media has emerged as a tool forcompanies to improve their communication with customers. The popularity of social media isincreasing at a rapid rate and sites such as Facebook now has around 500 million usersworldwide.

Poppel - en möjlighet i norra Sverige?

The countries in the European Union have agreed to increase their percentage renewable energy sources to 20 %. To reach this goal an increase of biomass production needs to be made. One way of achieving this is by using nonnative species. Poplar in Sweden produces biomass faster than the domestic trees. In the southern parts of Sweden plantations has been made with good results. In the northern parts survival is a problem that needs to be solved before plantations can be made for commercial use.

Djurparkernas tillgänglighet av information och dess innehåll: är den tillräcklig?

The purpose of zoos has changed over the decades. From being menageries where wealthy people showed their collections of exotic animals to today?s zoos where science, conservation and education has become a central part of their work. Education in zoos gives them the opportunity to spread the knowledge about ecology, biology and biodiversity to the general public. Their aim is to change the public?s attitudes towards our wildlife and raise awareness about the threats that exists against our planets biodiversity.

Fysiska strukturer i Umeälvens gamla älvfåra och dess inverkan på laxsmoltens utvandringsframgång

The survival of hatchery reared smolts is generally low after release. To get a better understanding of what variables affecting migration success, Atlantic salmon smolts were studied during their out-migration in the old river channel in the lower part of river Umeälven. The area consists of shifting habitat and complex structures which causes difficulties for smolt on their migration out to sea. The aim of this study was to try to determine the effects of feed restriction, fin conditions and different physical barriers in the river, on the migratory behavior of Atlantic salmon smolts in the river Umeälven. The river was divided into six different sections using acoustic receivers strategically deployed along the river. Two-year old hatchery-reared smolts (n=150), in three different weight classes, were tagged with acoustic transmitters.

Individuell tillväxt och substratval hos en lokalt differentierad population av Asellus aquaticus

Local differentiation may occur during a short period of time and is part of the formation of new species. The isopod Asellus aquaticus is an example of a species in which local adaptation has occurred during a short period of time. An establishment of stonewort (Chara spp.) vegetation in Lake Tåkern (in the 2000) resulted in two different Asellus ecotypes; a lighter pigmented, smaller one that lives among stoneworts grazing periphytic algae, and a darker, larger ecotype that feeds on decaying leaves in reed (Phragmites australis vegetation. The purpose of this study was to examine whether there are differences in growth between ecotypes, depending on whether the food was periphytic algae or leaves, and to study the choice of substrates between the two food types. For the study, animals from both habitats were brought in from Lake Tåkern to the laboratory.

Häckar för Smålands inland : en översikt

Häcken är ofta ett självklart och naturligt element i en trädgård. Som trädgårds-ingenjör kan det vara svårt att välja en lämplig häck till ett gestaltningsförslag. Det krävs att vi tar hänsyn till flera parametrar, både för att häcken ska trivas men också för att kunden ska bli nöjd. Det kan därför ta mycket tid att leta upp en häck som uppfyller alla krav och önskemål som finns, tid man oftast inte har. Syftet med det här arbetet är att studera lämpliga arter för häckar till villaträdgårdar i det småländska inlandet. Arbetet har gjorts med hjälp av litteraturstudier samt intervjuer med plantskolor.

Dogs on the move : a study of the travel habits of Swedish dogs and their owners? awareness of infectious diseases.

ABSTRACTThe principal aim of the study was to compare the feeding behaviour of cattle, sheep and goats on pasture and explain any differences between speices. Furthermore, I compared foraging behaviour between dry season and the beginning of the rainy season, in order to see any relationships between weather and behaviour.The study was carried out in Shompole in southern Kenya. Behavioural data were collected by observing herds of cattle, sheep and goats on pasture. The livestock were herded on pasture during the days and kept in bomas, where people live, during the nights. The weather in Shompole is characterized by high ambient temperature and low, bimodal rainfall.

Trauma, vittnesmål och etik. Representationens möjligheter och omöjligheter i Hayden Whites "The Modernist Event" samt i Shoshana Felman och Dori Laubs "Testimony"

This essay is a meta-theoretical study that aims to show normative and ethical implications that might follow from theories concerning representation of traumatic events in four essays from Shoshana Felman and Dori Laub?s Testimony. Crises of Witnessing in Literature, Psychoanalysis, and History and in Hayden White?s essay ?The Modernist Event?. Through a comparative analysis the essay mainly discusses how these writers deal with the problem of narrative.

Planering av design och skötsel i ett fragmenterat naturreservat

Rävsta naturreservat omfattar ett fragmenterat landskap som är mycket variationsrikt. När en skötselplan ska upprättas i ett sådant område är det viktigt att se till de hot som frag-menteringen medför som till exempel: för små habitat med för liten tillgång till resurser, avklippta spridningsvägar och kanteffekter. En ny skötselplan ska upprättas för reservatet under 2010 och det här arbetet syftar till att föreslå en modell som inriktar sig på att mot-verka de negativa effekterna som fragmentering har på den biologiska mångfalden. För att hitta de naturvärden som finns i området i nuläget har inventeringsdata från olika källor gåtts igenom. Data på arter som antingen är rödlistade eller indikerar höga naturvärden sammanställdes i olika grupper beroende på vilken naturtyp de är knutna till.

Handbok för växtinsamlare : med erfarenheter från sex nutida svenska experter

What makes a Swede betake himself into the Chinese wilderness? How does the Rio Convention influence a plant collector? And who will crack the nut positioned 12 meters up in the crown of a tree? There are many secrets behind the act of collecting plants. In many regards, the documentation of the collection of plants for a Swedish purpose has been unsatisfactory. The focus of the publications is on what plant species that have been found rather than information on how these plants have been collected. Only few results of experimental cultivation are available. There is no doubt that there exists knowledge that has not been publicised yet.

Beteenden hos geparder i två stora svenska djurparker

Cheetahs in the wild are declining due to hunting, lack of prey, exploitation of habitats and loss of cubs to predators. Those are the main reasons to why cheetahs are kept in captivity today for conservation. Many cheetahs kept in captivity are seen pacing ? a behaviour that arise when the animal is prohibited from performing natural behaviours. It is believed to being attributed to a lack of stimulation in the environment where they are being held.

Hägnutnyttjande hos Skansens lodjur (Lynx lynx)

Djurparker är idag stora attraktionsmoment samt arbetar också med bevarandearbeten. För att lyckas med ett bevarandeprojekt krävs det att djuren bibehåller sitt artspecifika beteende även i fångeskap vilket kräver ett bra hägn med tydliga mål. Det europeiska lodjuret är ett relativt populärt djur i djurparker i denna del av världen, och är än så länge inte hotade. Dock gör minskade habitat, avskjutning samt förändringar i bytestillgång att lodjurspopulationen minskar. På Skansen hålls två lodjur, en hona och en hane, i treårsåldern tillsammans i ett hägn.

Effect of Bacillus mediated priming on different natural genetic variants of Arabidopsis thaliana

In two feeding experiments Bacillus induced priming of plant defense was tested for its effect against the generalist insect pest Spodoptera littoralis. The main hypothesis for the study was that Bacillus induced priming would enable the plant Arabidopsis thaliana to defend itself better against this insect herbivore since this priming seems to involve jasmonic acid, known to be important for plant defense to insects. A secondary objective of the study was to examine if any differences in a primed defense capability could be seen between different natural genetic variants (ecotypes) of A. thaliana reflecting habitat differences in pest pressure. The methods used for plant cultivation and Bacillus inoculation were aimed at reflecting conditions that can be expected in an agricultural cropping system. This meant that all plants were cultivated in soil, and the feeding experiments were conducted with the plants growing intact in the soil system.

Ett slag för njutningen - En studie om BDSM-utövande inom relationer

The purpose of this study is to hightlight experiences of living in a relationship where BDSM is being exercised. The acronym is an umbrella term for bondage/discipline, dominance/submission and sadomasochism. The study is based on qualitative interviews with five persons who define themselves as BDSM practitioners. The overall questions of this study are: How does the BDSM practice appear in everyday life? How did the practice start and how has it developed over time? What's included in the sexual BDSM practice? The empirical material has been analyzed with interactionism as the theoritical framework. The picture that emerges is complex.

J K Rowling och fantasygenren : En genreteoretisk studie av Harry Potter

This paper attempts to display how five teachers of social studies use and relate to the policy documents and their instructions on gender. To penetrate the subject, five teachers were intreviewed. Each interview focused on how the curriculum attempts to guide teachers regarding gender, sex differences and equality of opportunity. The collected information was processed, analyzed and discussed using gender studies and discourse theory.The results show that the interpretation and usage of the curriculum is very subjective and varies greatly between all the interviewed teachers. Their personal interpretation proves to be crucial when it comes to making reality of the stated goals in the curriculum, concerning actively working towards equality of opportunity between sexes.
