A number of chemical agents, and their degradation products, have been recognized as having estrogenic activity on animals. On fish they interfere with endogenous estrogen and in many cases mimic its activity, thus increase estrogenic reponse, with elevated levels of vitellogenin. Hence they are called Endocrine Disrupting Chemicals, EDCs. Vitellogenin levels is often used as a biomarker of exposure to estrogenic pollutants. Wastewater from sewage treatment works contains chemicals known as EDCs, and there are evidence of roach (Rutilus rutilus) living in recipients of such wastewater having traits of both gender, i.e. oocytes in male gonads (intersex) on histological examination. This study was done on roach living in Lake Funbosjön Uppland, Sweden.

The horse was domesticated about 6000 years ago. Since then humans have used the horse for different purposes, such as work force and in sports. Horses are social, group living animals that spend around 16-17 hours a day on grazing. Horses are often kept stabled in single boxes with a limited feeding time. The forage usually contains grain-based concentrates and roughage.

Development of morphs within European whitefish (Coregonus lavaretus), might be considered as a beginning of a sympatric speciation process. Unpublished data suggests that presence of the keystone piscivore northern pike (Esox lucius) is the main driver of sympatric divergence in European whitefish (Coregonus lavaretus). Using introduced whitefish populations as controlled experiments, it is possible to determine when different characters diverge in the speciation process. In this study, I analysed age and growth within European whitefish populations of different age to assess if these characters change over time in absence of pike. With using otoliths from whitefish populations of different age, I was possible to determine individual age, and by measuring the length of the fish, growth was calculated.

I dagens samhälle kretsar shopping inte bara kring själva produkterna som säljs, utan även om hur butiksmiljön är uppbyggd. Den visuella miljön och hur produkter presenteras har stor påverkan på kunders beteende och inköp. Ljus, ljud och färger påverkar våra sinnen både positivt och negativt, vilket butiker utnyttjar på olika sätt. Syftet med detta uppsatsarbete är att beskriva vad unga kunder (18-25 år) anser ska ingå i ett attraktivt och starkt butikskoncept. Syftet är också att undersöka hur unga kunder upplever likheter respektive skillnader gällande butikskoncept för butikskedjor och produktutvecklande varumärkesleverantörer.

Restoration projects are planned and carried out in order to reduce the impact due to anthropogenic influence and to achieve at least good ecological status according to the EU Water Framework Directive. The resilience effort of such restorations is however ambiguous. The aim of this study was to evaluate the potential of follow up restoration measures in Swedish lakes and streams. In particular, we visualized the geographical spread of restoration measures in Sweden and quantified the different types of measures that were implemented so far. Further, we evaluated the extent of sampling of biological factors before and after the restoration measures have occurred. For the purpose of our study, we used the recently compiled national database of restoration measures in Swedish lakes and streams.

Människor spenderar en stor del av sin tid på arbetet och därför är arbetsmotivation viktig för att de anställda ska trivas på arbetet. Enligt Amabile (1993) anses hög arbetsmotivation öka individens välmående och anses bidra till arbetstagarens kreativitet och produktivitet. I detta examensarbete har patienthotell Vistet i Sunderbyn, ett komplement till vårdavdelningarna på Sunderby sjukhus som strävar efter en hälsofrämjande miljö för att uppmuntra läkning undersökts (Norrbottens läns landsting, 2015). Syftet är att få en inblick hur patienthotellet har skapat en arbetsgrupp, undersöka hur sammansättningen av arbetsgruppen bidragit till arbetsmotivation, samt undersöka vad de anställda på patienthotellet motiverades av. Arbetet baseras på 11 intervjuer; verksamhetschef, sjuksköterskor, undersköterskor och servicemedarbetare ingår.

The business cycle of the wood flooring branch is currently high however that situation may not be sustainable. In a possible future weaker business climate, the importance of marketing becomes accentuated for firms that aim to maintain their sales levels. We can see trends that competition among the Swedish and foreign manufactures is already stepping up. The intent of this study is to establish marketing guidelines for floor- and molding manufacturers, so they can establish a clearer brand image in DIY retail outlets. By comparing the approach of sports- and DIY stores to brand and product placement, this study aims to bring new knowledge to the DIY branch for improved consumer and product handling.

The purpose of this study was to create a deeper understanding for, and shine a light on the exit process for former criminal gang members. Which conditions appear to be important and what may constitute the enabling and inhibiting factors of an exit process? The study was based on qualitative semi-structured interviews with respondents who themselves have experience of a criminal lifestyle and gang affiliation, and with professionals in social work. Our theoretical approach is based on Helen Ebaugh?s definition of an exit process, labeling theories, strain theory and control theory.

Uppsatsen presenterar två studier som med den socialpsykologiska modellen ?teorin om planerat beteende? (Ajzen, 1991) undersöker hur väl en webbaserad måltidsplaneringstjänst lyckas med att få dess användare att regelbundet äta varierat.Tjänsten bestod huvudsakligen av en sökbar receptdatabas på 250 recept, en kalender för att planera in recepten i, och en inköpslista som genererades automatiskt utifrån recepten i kalendern. Tjänsten byggdes under tiden som uppsatsen skrevs, och författaren deltog som interaktionsdesigner i detta projekt.I  uppsatsen presenteras  två sekventiella studier för att mäta användarnas intention till beteendet. I vardera studie presenteras först webbtjänsten och den funktionalitet den hade vid tiden för testet. Detta följs av en hypotes om tjänstens påverkan över användarnas vilja att äta varierat.

Pica is a behavior that can be seen in several animal groups. In cats, it means that they are eating, chewing or licking on material that is non-food. In this study the data was collected through an online survey. In total 522 responses, of which 26% of the cats were exhibiting pica. It was found that 28% of the housecats and 26% of purebred cats exhibited pica.

Predation is a strong dective force on invertebrate prey. Asellus aquaticus differs in pigmentation reed and submerged vegetation habitats in lakes. Light pigmented individuals al vegetation dominated by Chara sp. while dark pigmented individuals dominate in the reeds. These differences have been hypothesized to result from background matching.

Coping theory asks what the cognitive and behavioral patterns of individuals dealing with stress are. This essay includes, besides the perspective of the psychology of religion, theories of culture and ritual in exploring two Swedes coping with the natural disaster in Thailand year 2004. The vacation paradise was struck by an enormous flood wave, called a tsunami, causing vast destruction and the death of over 200.000 people. Among these 543 were Swedes on vacation. When a disaster of such measures happens, what kind of stress does it cause? How do you cope? Are religion and ritual important? What is the function of the culture in the copingprocess? Using hermeneutical analysis this essay interprets the material from two books by Swedes, who not only experienced the disaster, but lost two children and husband and wife in the flood wave.

Detta är ett naturvetenskapligt arbete som omfattas både av en kvantitativ och en kvalitativ undersökning. Syftet med arbetet är att undersöka mellanskarvens födoval i sjön Sommen, samt att närmare studera huruvida det unika beståndet av röding och öring ingår i mellanskarvens födoval. Sommens Fiskevårdsområde har fått tillstånd till skyddsjakt på mellanskarv av Länsstyrelsen och det främsta skälet skulle vara att fågeln prederar röding och öring. Genom att analysera mellanskarvens spyboll och jämföra innehållet med referensfiskar fångade från samma sjö ska vi se om beslutet från Länsstyrelsen är befogat. Insamling av spybollar och referensfiskar utfördes i fält medan analys av spybollar utfördes på laboratorium.

Ever since Internet revolutionized the world, e-stores and e-commerce has grown into becoming a natural part of consumer's everyday life. Much thanks to it's facilitative and time saving characteristics. Online, consumers are provided with a huge assortment and the opportunity to shop any time they like. Yet, the absolute greatness of e-stores is the possibility to push prices below the physical store price, which seems to be most appreciated to a large extent by consumers worldwide. The fact that e-store sales in Sweden grew 14% last year verifies this.As more players step into the virtual world of e-commerce the competition gets tougher.
