The effects of prey size on prey choice in different cohorts of juvenile turbot (Psetta maxima)were studied in three nursery areas at Gotland. Prey length measurements showed that gobies(Gobiidae) increased in average length during the season, while mysids (Mysidae) did not.Experiments on predation capacity of different size classes of turbot on different size classesof prey showed that juvenile turbot easily can eat gobies that are up to two thirds of their ownbody length, while the body size of turbot does not have any effect on the predation capacityon mysids. Stomach content of 217 turbots, less or equal 35 mm, was analysed to see if therewas any change in diet during the season, but there was no significant change in diet. Theoverall conclusion was that early settlers most likely have an advantage due to greater accessof alternative prey..

The aim of this study was to examine if biological early maturing girls and girls that percieved that boys treated them as older than they actually where drank more alcohol, were more delinquent, had more romantic relationships and sexual intercourse. Our data was collected from seven schools in Sweden. Significant relationships where found between early maturation and all four dependent variables. Significant relationships could also bee seen between how girls perceived that boys treated them and alcohol use, romantic relationships and sexual intercourse. For two of our dependent measures we found week interaction effects, for girls biological maturation and there perception of how boys treated them according to there age.

Under senare hälften av 1990-talet har narkotikamissbruket i Sverige ökat. I denna uppsats undersöks huruvida detta har påverkat den övriga brottsligheten genom en analys av data frånen panel bestående av samtliga svenska län 1995 ? 2004. En Fixed-Effects- modell som kontrollerar för läns- och tidsspecifika effekter har anpassats till datamaterialet. Måttet på narkotikakonsumtion är baserat på den årliga enkätstudie som genomförs bland 18- åriga män som mönstrar till värnpliktstjänst i Sverige.

In this paper I study how the repeal of the Swedish wealth tax (1 of January 2007) has affected people´s labour supply behaviour. This particular issue is relevant because it may help us understand some of the effects of the earnings tax changes that have taken place in Sweden. Accoring to standard economic theory a repealed wealth tax is similar to an income effect for the persons who previously paid the tax. That means that they theoretically will want to consume more leisure, that is decrease their labour supply. The method I am using to test this hypothesis is a difference-in-difference approach where the treatment group consists of persons who previously paid the tax and the control group of comparable persons who did not pay the tax.

In this paper respiratory sinus arrhythmia (RSA) was examined in relation to two kinds of threatening pictures, biological and nonbiological. Based on the results of prior research the hypothesis was claimed to note a difference between the two types of pictures regarding RSA and gender differences regarding cardiac activity due to the emotional stimulus. ECG and respiration were collected from 36 adults, 17 women and 19 men. There were no significant relationship between the different types of threatening pictorial stimuli, and no significant effects of gender were found. The results support some of the prior research on the topic but are in conflict with other.

Studien undersökte om, och hur, Google Kalender kan användas som hjälpmedel för vuxna individer med ADHD.

Despite the vast research on the effects of gaming, little is know how the phenomenon of e-sports and it?s followers is portrayed. While media can have significant impact on what and how e-sport is portrayed, no studies have been done in a Swedish context. This thesis aims at filling that gap with investigations of the two major Swedish newspapers. Six articles was analyzed with critical discourse analysis with a theoretical base of journalism.The result of which indicated that between the period of 2005 and 2012 e-sport and players was considered to be professional, committed and more in a sense that reminded much of the view on more traditional sport such as soccer and hockey.

Is there such a thing as unadulterated nature? All that surrounds us is culturally modified by man somewhere along our past. But culture is only a fictitious conception itself, created in an attempt to break the world into controllable objects.So in what do we find culture? In everything? In the objects or the stories they embrace? Who chooses what?s worth saving and how to save? Choosing what is culture is made from personal, ingrained dichotomies of what?s important and what is not. A selective eye creates a distorted truth, which could have unintentional long-term effects.This thesis will give a historical account of the archaeological discipline?s development in tending to our cultural heritage.

This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.

The mouse (Mus musculus) is the most commonly used mammal in biomedical research and can easily be restrained by both hand and by a device. Restraining animals causes stress that not only decreases the animal?s wellbeing, but may also influence the research results. The first aim of this study was to train mice to voluntarily stand still using positive reinforcement training. Another benefit of teaching a mouse to stand still is that you can avoid anaesthesia for some procedures.

The aim of this essay was to investigate how religious topics and events are presented in five coursebooks in social studies. To do this the following questions were answered: In which context do discussions about religion take place? Are religions brought up in different contexts? To which extent do discussions about religion occur? The method consisted of a both quantitative and qualitative content analysis. The results of this essay showed that discussion regarding religion in social studies coursebooks mainly focuses on wars, conflicts, terrorism and to some degree the human rights. Islam was the religion that occurred most frequently in the coursebooks.

The aim of this study is to investigate the effects ofWork plan for study- and vocational guidance in Enköpings municipality 2008-2010 to see how it has affected the educators in the municipal primary schools. Questionnaires to teachers and interviews with principals have been made and it came out that the teachers are not very familiar with the plan. Of the few teachers who considered themselves to be familiar with the plan, the majority replied that they had benefited from the plan.The study´s analysis indicates that one of explanation for why so few educators are aware of and working according to the plan is partly in implementation efforts. Weaknesses are shown according to the equivalence of the implementation, but also the importance of the existence of an engaging and driven person, located at the primary schools, that continuously inspires and motivates the teachers to work with this plan. Educators also indicate that they already use study-and vocational guidance in their teaching..

This study aimed to investigate whether lambs show anticipatory behaviours in a holding pen prior to entering a known arena, whether the holding pen experience prior to the arena exposure affects their play expression in the arena and whether their behaviour (in home pen) is affected if arena access is denied. Twenty pair-housed male lambs (average 14 weeks old), were exposed, in chronological order, to five treatments. Holding pen treat-ment (HP-control): Each pair was led into a holding pen (2.7 m2) and remained there for 5 minutes before returning to their home pen (6 m2). Holding pen ? arena treatment (HP-A): Each pair was led into a holding pen for 5 min and then was allowed access into the arena (22 m2, containing two hanging chains, one ball and one platform) for 15 min before re-turning to their home pen.

Syftet med uppsatsen, att utreda de skillnader i rättsverkningar som finns mellan Natura 2000-områden och vanliga naturreservat,har jag uppnått genom att använda mig av traditionell juridisk metod. Genom att jämföra lagtextformuleringar, förarbeten och bakgrund till bestämmelserna om de två områdesskydden har jag funnit att reglerna om Natura 2000-områden har en betydligt större räckvidd än bestämmelserna för vanliga naturreservat. Allehanda verksamheter och åtgärder omfattas av den särskilda tillståndprövning som gäller för ingrepp i Natura 2000-områden, medan vanliga naturreservat har begränsad räckvidd till de ingrepp som stadgas i reservatsföreskrifterna. Jag har även funnit skillnader när det gäller inrättandet och upphävandet av områdesskydd, och resultatet är att EU-kommissionen utövar en stark kontroll vad gäller Natura 2000-områden. Kommissionen kan tvinga medlemsstaterna att inrätta särskilt skyddat område, och om medlemsstaten vill upphäva skyddet måste samråd ske med kommissionen.

Which expectations did leading debaters place on fiction as an instrument in achieving societal changes hoped for by introducing the Public library? How can the value of fiction be described in relation to the mission of the Public library, according to these moulders of public opinion? Place and timeframe for this thesis is Sweden around the years 1905-1912 (period of formation of the Public library here according to the Anglo-American model). Starting point is the assumption that the Public library as a political institution is characterized by an ideological function. It produces meaning and norms, it sets standards of value. Method used is based on close reading and comparison.
