The purpose with this essay was to see how the mathematic books showed sexual roles in pictures and if they confirm or deny the traditional sexual roles that school shall counteract according to the curriculum, Lgr11. The questions I focused on were this:How sexual roles are introduced on the pictures in the chosen mathematic books?What are the similarities and differences between the presentations of the gender in the chosen education materials?I used a semiotic method to analyze my pictures. The central parts of my theories were how we think that gender is created using characteristics and attribute. In my analyze I found out that the pictures in one of the book series showed more stereotypic sexual roles than the other book series did..

Several studies have shown that people misjudge and fail to correctly combine probabilities. An explanation for these tendencies is the conjunction fallacy. Basically, the conjunction fallacy refers to violations of the conjunction rule, which states that the probability of a combination of two independent events (A & B) cannot exceed the probability of neither event (A or B). In connection with the growth of the Swedish gambling market and the fact that betting is an everyday-event containing well-defined probabilities, it is considered to be both up-to-date and relevant to study whether the conjunction fallacy also occurs in betting. Previous studies have shown that people fall victims of the conjunction error, however, only in controlled laboratory settings.

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.

Traditionally the content of fiction has not been described, analyzed, classified and/or indexed to the same extent as non-fiction. As a consequence, this lack of content analysis has resulted in unsatisfactory fiction retrieval in relation to users seeking and search behaviour. This fact is why this Master s thesis is written. The total of library users' seeking and search behaviour is investigated in order to suggest methods to improve user adapted fiction retrieval tools. Suggesting relevant fiction retrieval tools corresponding to users' seeking/search behaviour is another aim of the study.

Horses are grazers with a digestive system that is adapted for a high fiber diet. Forage is a fiber rich feed that includes grass and legumes. A deficiency of forage and an excess of grains may cause gut disturbances and stereotypic behavior. The aim of this literature study was to summarize information on the horse?s capacity to consume forage-only diets with focus on the horse?s need of energy and protein.

Background: From a public health perspective it is of great interest to prevent the risk of noise induced hearing loss, because in addition to hearing loss, tinnitus and sound sensitivity also may lead to other health problems. About 1,4 million people in Sweden live with some form of hearing loss and 25000 of them are children under the age of 16. Studies have shown that hearing loss among adolescents is increasing and it is often associated with sound environments in their leisure time. Lectures in hearing prevention has been conducted in schools for adolescents but have not reached the desired results. Objective: To enquire caregivers? attitude, behaviour and perceived knowledge about sound exposure and its risks.

Relationship between social behaviour, feeding behaviour and performance of boars using single-space feeders A study on the behavioural patterns of growing boars is presented. The study was preformed at Quality Genetics? boar testing station Månseryd in Sweden. The boars were purebred Yorkshire, Hampshire or Landrace, born in nine different nucleus farms. The study is based on two batches of boars, with 63 and 69 boars respectively.

The abrupt and early weaning of intensively kept lambs may have serious animal welfare implications, but relatively little is known about this. Weaning includes the breaking of the mother-young bond and abrupt replacement of milk by solid food, often coinciding with changes in the (social) environment. Altogether, these changes are likely to affect lamb welfare significantly. This study aimed to establish how strong and persistent lamb welfare is impaired following abrupt weaning by means of measuring behaviour parameters indicative of affective state. Also, we investigated the existence of a diurnal rhythm in play behaviour, which is considered an important indicator of positive affect and good welfare.

The purpose of this thesis is to examine Skogsstyrelsens event Skogens Dag as an information channel by looking at information use and information behaviour during the communication process of the event. This is done by examining the aims of Skogsstyrelsens information distribution during the event in relation to its outcomes. The evaluation is focused on long term effects on the target group and it is restricted to Skogens Dag in Borås 2005. The question this thesis intends to answer is: How does the event Skogens Dag function as a tool for information distribution? The theoretical background gives an account of the communication process as well as the relevant aspects of marketing, social marketing, campaigns and public relations, as these are communication attempts that can use an event as a medium.

It is reported that adolescents' health is deteriorating, when their mental illness has increased. Adolescents' social conditions have also become worse. The mental illness is linked to the individual living conditions. The purpose of this study is to investigate which factors adolescents experience have been contributing to making a lifestyle change. The apparent factors can be used to promote adolescents´ health.

The use of marketing research panels are a more and more frequently used source of information for studies within many different branches. The purpose of this report is to investigate the demographic composition of panels and compare it with the population of Sweden, a possible change in behaviour of respondents, and if the source of recruitment is the cause of possible differences in study results. The study was commissioned by Norstats Linkoping office. Sources for the data material include Norstat?s recruitment process and their two main panels with different recruitment sources.

Oestrus in dairy cattle has changed over the last decades; the intensity of oestrus has declined and the duration decreased. Several studies have shown that not all dairy cows stand to be mounted, and that oestrus expression in many cases may be characterized by other behaviours. The aim of this study was to investigate oestrus behaviour in a herd of todays? high producing dairy cattle. The study was carried out at Jälla naturbruksgymnasium in Uppsala during one week in January 2011.

Our purpose with this research has been to obtain a deeper insight and understanding for the phenomenon and term ?weekday-luxury.?Through our research, we have found a link between value, service, brands and consumer behaviour into a relationship that we termed ?weekday-luxury.? This link of values is particularly interesting to us and we are curious about the underlying motivation to ?weekday-luxury? and the driving forces underlying the phenomenon. We have noticed in society that people need something extra in their daily lives and we attempt to speculate where their perceived value lies through the concept of ?weekday-luxury." Our goal is to determine a deeper understanding and insight into this phenomenon and how it meets our needs through an identifiable pattern. We also analyze the nature of ?weekday-luxury? and its meaning.

An energy study has been performed on two blocks in an area called Gävle Strand. The buildings are owned by a tenant-owner?s association called brf Carolina and were built by the company Skanska 2008. The builder as well as brf Carolina are pussled by the fact that electricity use is higher than expected while heating is less. Skanska is also very interested in finding out how much heat recovery from stale exhaust air through a geo-thermal heat pump is contributing to the general heating requirement and energy balance in four out of the ten buildings located on the properties.To find possible answers to the higher electricity use a literature survey on user behaviour was conducted.

The purpose of this essay was to analyze if and how teenagers think about immigrants and Swedes, the relationship between them and to find out where these thoughts originate from. The essay consisted of four main questions; do the teenagers think in terms of immigrants and Swedes? How do the teenagers reason in terms of who is an immigrant and who is Swedish? What do they think about the relationship between immigrants and Swedes? Where do these opinions originate from?The study was based on eight interviews conducted with teenagers born in 1987. Our conclusion of the study was that it is not easy to determine who is Swedish and who is not. It was clear in this study though that looks and behaviour were utterly important.
