Människan är nyfiken och vill finna ny information på webbplatser. Detta kan underlättas med hjälp av virtuella doftspår som användaren följer. Denna rapport är en fördjupning i hur människan går tillväga för att följa virtuella doftspår och hur man som designer ska använda sig av detta när man utvecklar en webbplats. Genom teorierna information foraging och användbarhet har en användbarhetsmodell och en operationalisering tagits fram för att underlätta detta. Tillsammans med datainsamling genom intervjuer och metoderna heuristisk utvärdering och high fidelity har studien visat att när man skapar ett gränssnitt för användare behövs information foraging som bestämmer eller lämnar förslag på hur virtuella doftspår påverkar användaren..

Detta arbete har utförts i samarbete med företaget Compute och fokuserar på att utveckla navigationsstöd för webbportaler med bokningssystem. Arbetet har delats upp i tre specifika mål: (1) integrera Information Foraging Theory (IFT) och Graphical User Interface principles (GUI-principer) genom att applicera dessa vid utvecklng av navigation för webbportaler med bokningssystem (2) konkretisera hur navigering kan förbättras på en webbportal med bokningssystem, utifrån ovanstående teroier och (3) arbetet skall resultera i en lista med rekommendationer som kan tillämpas vid utveckling av navigation. För att kunna  integrera IFT och GUI-principer har dessa i kombination med en teroertisk studie tillämpats vid prototyping. Prototyperna användes som verktyg för att konkretisera hur navigationen kunde förbättras på portalen. Prototyperna utvärderades och resulterade i en lista med rekommendationer.

Animals in zoos live in more barren environments than their conspecifics in nature. In nature, elephants spend more than 75 % of the day foraging and have been observed lying down two hours during night. Stereotypies are common in many different species in zoos. Stereotypic behaviors may constitute up to 50 % of the daily activity budget of zoo elephants. Modern zoos try to reduce stereotypic behaviors by means of environmental enrichment.

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.

Företag som bedriver handel via nätet på sajter som inriktar sig mot privatpersoner satsar idag mycket på att utvecklas för att på bästa sätt stödja kunden mot sitt mål. Dock har företag som inriktar sig mot andra företag (B2B-business to business) inte hängt med i samma utsträckning. Den här rapporten syftade till att undersöka hur man kan arbeta för att ta fram ett designförslag på en B2B-sajt, närmare bestämt vilka metoder och teorier man kan dra nytta av. Metoder och teorier som har använts är effektkartläggning, Coopers målinriktade designmetod, Nielsens designprinciper för användbarhet och information foraging. Arbetet resulterade i en prototyp kring vilken en diskussion fördes följt av slutsatsen att valet av metoder och teorier tycks vara en lämplig kombination vid utveckling av B2B-sajter men att ytterligare forskning krävs för att skapa en enhetlig metod..

The purpose of this study is to examine some factors that make a human grouse hunter to prolong and increase its hunting effort. The theory of optimal foraging is used for explaining their behavior.The data of this study is collected from a web-based inquiry from 2007 answered by grouse hunters in Sweden. The method that has been used is mainly bivariate statistics and logistic regression analysis.Key findings shows that an experienced grouse hunter has more than 5 times the chance of prolonging hunting effort when grouse density is high, compared to a beginner grouse hunter. On the same time experienced grouse hunters also stop hunting in advance when grouse density is low to a larger extent than inexperienced hunters. Other factors of importance for prolonging the hunting effort for a day are age and the travel distance to the hunting area.

Animal welfare is impaired if the diet does not provide sufficient feeling of satiety or the ability to perform natural feeding behavior. Pigs are omnivores and spend most of the day searching for food by rooting, grazing and chewing. Both inability to perform foraging behavior and insufficient feeling of satiety often leads to direction of foraging behavior towards stereotyped and abnormal oral behavior. Dry sows are often fed restrictively which leads to unsatisfied feeling of hunger. Dietary fiber has been found to reduce stereotypic and abnormal behavior as well as aggression, which could indicate that pigs need to forage has been met giving a feeling of satiety.

The red-tailed monkey (Cercopithecus ascanius) is a small, alert and active animal inhabiting forests with dense vegetation and as such hard to observe in its natural habitat. The principal aim of this study was to scrutinize whether the methods, previously used in a behavioural study of the blue monkey (Cercopithecus mitis) can be applied in studies of the red-tailed monkey?s behaviour as well. Additionally, habitat preference and foraging behaviour of the red-tailed monkey were examined. The study was carried out between the 16th and the 22nd of March 2009 in the Sabaringo forest, located on the western border of the Masai Mara National Reserve.

In this study the spawning migration activity, habitat choice (depth and temperature), foraging activity, duration of stay in the spawning site and homing-behavior was studied for anadromous pike (Esox lucius) in the wetland Österby myr, Gotland.The spawning migration was concentrated to dusk and dawn, a homing behavior was confirmed and there was no significant difference between sexes with respect to duration of stay. A difference in habitat choice and small variation in foraging activity between individuals was established..

Elephants are hindgut fermenters, which affects their diurnal rhythm. To reach their nutrient demands, elephants must eat almost constantly throughout the light part of the day. Sexual dimorphism may also affect their behavioral patterns. To understand the elephants' normal living habits and foraging behaviour, we conducted a pre-study in the Mara Triangle, the north-western part of the Maasai Mara National Reserve. Each of four to six observers randomly chose a focal animal within the group of elephants by the criteria that they were adults and visible.

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.

The aim of this masters thesis was to study how the members of a small non-profit organisation perceived the web forum, compared to the other information channels of the organisation. The organisation was defined as a virtual community. A literature review was conducted. The theory construction was based on the sensemaking theory. Interview questions were constructed based on the literature review and the sensemaking theory.

Today there is a research project undertaken by the Swedish University of Agricultural Sciences along with Wången (a highschool specialized in trotter training), which focuses on trotting horse training, performance and health. The project investigates how exercise intensity and feeding strategies affect the development of growing horses. The project includes two groups of horses where all 16 horses are fed in the same way. One group of eight individuals are trained 100% compared to conventional training and the other group are trained 20% less than the other group. All horses are trained twice a week and are out at pasture beyond that.

I denna studie testas tio hypoteser som relaterar till finansiell teori för att se hur väl teorin kan förklara skuldsättningsgraden i små börsnoterade bolag. De teorier som testas är avvägningsteorin (trade-off theory), hackordningsteorin (pecking order theory) samt teorier relaterade till asymmetrisk information och agentkostnader. Testen genomförs med multipel linjär regressionsanalys och de undersökta bolagen är samtliga bolag med färre än 200 anställda på tre av de mindre börslistorna i Sverige. Resultatet visar stöd för åtta av de tio undersökta hypoteserna och är i flera avseenden tydligare än i tidigare studier som testar onoterade små bolag eller ett bredare urval av bolag..
