Korrigering för slumpfel och metodeffekter i sambandsanalys av enkätdata med SQP 2.0
Sambandsanalys av surveydata kompliceras av förekomsten av slumpfel och metodeffekter i de avgivna svaren. Dessa felkällor kan leda till betydande över- eller underskattning av sambanden mellan undersökta variabler, och riskerar att leda till felaktiga slutsatser.En sedan länge känd metod för att estimera och kontrollera för slumpfel och metodeffekter i enkätdata är den så kallade Multitrait Multimethod-metoden (MTMM). Nackdelen med MTMM-metoden är att den kräver att varje fråga som ska analyseras ställs minst tre gånger i samma enkät, vilket gör att ansatsen i praktiken oftast inte är möjlig att tillämpa. Sedan 2012 finns dock ett verktyg, SQP 2.0, som gör det möjligt att skatta slumpfel och metodeffekter i enkätdata utan att genomföra MTMM-experiment. Den här uppsatsen utvärderar prediktionerna från SQP 2.0 på en enkät om arbetslivsrelaterade frågor besvarad av svenska och brittiska respondenter.
Vad ska vi göra nu, när vi gjort så? - en studie i tvåspråkiga elevers kommunikation under laborationer
Syftet med denna studie var att undersöka hur tvåspråkiga elevers kommunikation under två olika laborationer såg ut, hur laborationsuppgiftens utformning påverkade dessa elevers kommunikation och även hur laborationerna kunde ge eleverna möjlighet till reflektion runt innehållet. Elever i årskurs 7 observerades och spelades in på band vid två skilda laborationstillfällen. Intervjuer utfördes efter det sista laborationstillfället. Undersökningen tyder på att elevernas kommunikation och möjligheter till reflektion i stor utsträckning påverkas av laborationens utformning och innehåll..
NO-undervisning i klassrummet : En observationsstudie i hur undervisningen bedrivs av fem lärare på en skola
This essay is based on students' growing lack of interest in science at school. Both from a democratic and social perspective, this is a worrying factor for the future. Through observation, I investigated how five science teachers conduct their teaching. This is to get a better understanding of how teachers' behaviour in the classroom can affect students' interest in science. With a socio-cultural research approach, I have tried to highlight a few pieces of the puzzle that may explain students' declining interest in science.
Rörelse i en sydafrikansk skola : En studie om lärares syn och tillämpning
AbstractAccording to a lot of people, movement contributes with a whole lot of positive things such as, learning, a better bodyknowledge, fellowship and koncentration. Movement has also proved to support many things regarding childrens development. According to Gun Sandborg-Holmdahl who is a teacher in pedagogic and Birgitta Stening who is an physical education teacher, movement and games commits many of the human senses wich contributes childrens ability to use their amagination and also spontanity. Games and movements have also shown to have good effects when it comes to childrens increased feeling to learn things. I have in this study, studied the South African school and their wiew on movement in school.
Musiklärare på ett högstadium - En fallstudie på två lärare ur ett jämställdhetsperspektiv
Syftet med denna uppsats är att belysa hur medvetna musiklärare är om jämställdhetsperspektivet i sin undervisning, om det finns skillnader mellan manliga och kvinnliga lärare och hur lärarna ser på de budskap och värderingar de förmedlar i sin undervisning ur ett jämställdhetsperspektiv. Undersökningen genomfördes på en skola med hjälp av observationer och kvalitativa intervjuer av berörda lärare. De resultat jag kom fram till var att lärarna, en manlig och kvinnlig, i stort sett behandlade sina elever på ett jämställt sätt. Det förekom tendenser till upprätthållande av traditionella könsmönster, men i liten skala. Av resultaten har jag dragit slutsatsen att jag i princip har fått svar på mina forskningsfrågor, men att det skulle behövas mer forskning på området och i större skala.Music teachers at the upper level of compulsory school - A case study of two teachers in a gender perspectiveThe purpose of this article is to illustrate music teachers awareness of the gender perspective in their teaching, if there are any differencies between male and female teachers and how the teachers think about the messages and values they share with the students in their teaching in a gender perspective.
Dried distiller?s grains with solubles and Swedish grown soya beans as protein feeds for dairy bull calves
The cattle production in the world has been questioned in Sweden due to its negative impacts on the environment. The use of imported soya bean meal as a protein feed for Swedish cattle results in the cutting of rainforest and an extensive use of pesticides in the countries were the soya beans are produced. As a consequence, the environmental impacts caused by cattle production increases. A production of protein feeds in Sweden would decrease the transportations and the cutting of rainforest. For organic beef producers the possibility to produce home-grown protein feeds is important since organic protein feeds can be difficult to obtain in another way.
Does social activity and management routines affect the horses interest for humans? :
This work focuses on the relation between human and animals and especially on the relation between horses and human. I have brought up the human och horse relationsship, today, and in history and wrote about the behaviour of the horse. Some older studies with human and animal interaction, including animals like dog and cattle are discussed. I have also discussed physiological parameters that might influence the bond and the interaction between human and horse and some critical aspects concerning the methodology when studying this kind of physiology.
The purpose of the experimental study was to analyze if common management routines and grooming of horses increases horses interest in making contact with humans. Many horse owners feel that they have a good connection with their horse and factors that can influence the relationsship could be physical contact, feeding or some challange that make the horse trust the human.
The effect of rapeseed oil and palm oil supplement and milking frequency on milk yield and milk fat quality
Milk fat is an important feature in many different milk products and other foodstuffs and it is often crucial for the dairy plants that the milk fat is stable for different manufacturing processes. Lipolysis is the enzymatic degradation of fat and is the one of the causes for an elevated amount of free fatty acids (FFA) in milk. Further, the change in fatty acid (FA) composition in milk can affect the stability of the product and also the manufacturing process. Both internal and external factors, at farm level or at the dairy plants can affect both FA composition and content of FFA. Milking frequency (MF=number of milkings per cow and day) and the composition of feed are two examples of factors generally performed at farm level.
The objective of the present study was to evaluate how FA composition of milk and amount of FFA are influenced by two different ingredients supplemented to concentrate.
Fire impact in the wood quality and a fertilization experiment in Eucalyptus plantations in Guangxi, southern China
Chinas government has a multifunctional program for a more sustainable forestry since 2000. This six key forest programs goal is to develop a more sustainable forest sector but also take environment consideration. The state forest administration in China has decided to create 5.8 million hectare of fast growing and high yield forest. Eucalyptus has showed to have good properties for pulp and timber production and therefore Eucalyptus plantations are under development in costal areas in southern China. By adding extra nutrients, growth can be enhanced in Eucalyptus plantations.
Inverkan av utfodringsnivå och miljö på reproduktion och hållbarhet hos rekryteringskvigor :
This study is based on an earlier interdisciplinary study made by Redbo et al., (2000), Extensive cattle production systems ? out wintering, which lasted over two winters, 97/98 and 98/99, with two groups of heifers indoors and two groups of heifers outdoors raised in different environments, indoors or outdoors during their second winter. Both indoor and outdoor heifer groups were fed grass silage ad libitum throughout the experimental period that lasted from October until May. The objective of this study was to evaluate the long term effects of being raised in these two environments. This study includes data collected during the period lasting from the start of the experiment of Redbo et al., (2000) until the heifers had calved a second time and the results mainly deal with the performance of the animals after the experiment during their first two calvings and their first lactation.
Nedbrytning av propylenglykol i uppsamlingssystem för avisningsvätskor : En studie utförd vid Stockholm Arlanda flygplats
Deicing fluids based on Propylene glycol are used at Stockholm Arlanda airport to remove or prevent ice on aircrafts. The high oxygen demand of propylene glycol can cause oxygen depletion in rivers downstream from the airport if not collected. Mass balance calculations made by Swedavia indicate that the actual amount of gathered propylene glycol is underestimated. Suspicions that propylene glycol is degraded in the stormwatersystem designed to collect deicingfluids, called the B-glycolsystem, have to be investigated in order to establish with certainty that no propylene glycol in other ways leaves the B-glycol system.The purpose of this study was to determine if degradation of propylene glycol is present in the B-glycol system and also to estimate the extent of the degradation. Propylene glycols high biological oxygen demand can cause oxygen depletion in waters downstream from Stockholm Arlanda airport if not collected.

AimThis qualitative study will provide an insight to different teachers view on handball in two elementary schools. Handball is a competitive sport and has been played for over 100 years in different contexts in Sweden. Are there qualities in the sport that belongs in the school´s non-competitive education? How do they justify this sport according to the governing documents Lgr-11 that gives a lot of room for interpretation by the teachers?How do teachers justify handball based on the curriculum?What kind of qualities do the teachers highlight with this sport in the education?Do teachers perceive any differences with the new curriculum?MethodThe method has a qualitative approach. The interviews in this study had a semi structure character.
En annorlunda undervisningsform i religionsämnet : En studie om Abrahams Barns undervisningsmetod
This article is about Abrahams Children foundation and its teaching method called IE- method. It?s about how a teacher can use the IE- method in the religion lesson. There were some questions in this article that had to be answered and the questions are:- How is the form of the religion classes when a teacher uses the IE- method?- What happens in the class when you study the interaction and the communication?- Does the student?s participation increase when they work with the IE- method?- What are the advantage and the disadvantage with the IE- method?- Can the teacher use the IE- method in other classes?To get to the ?correct? answer I used many methods like, observation in the class, qualitative interview with the teacher (Lisa Andersson) and with four students (Kim, Erik, Amanda, Patrik) and I also used questionnaire.
Lögner i moderna kommunikationsmedel
Lögner är vanliga mellan människor och förekommer i olika kommunikationsmedel. Det är av intresse att få kunskap om lögner bland annat inom budgivning på fastigheter, sjukanmälan och otrohet. I detta examensarbete undersöks experimentellt förekomsten av planerade lögner vid kommunikation ansikte mot ansikte, telefonsamtal och textmeddelande med mobiltelefon (SMS) vid förutsättning att lögnen är planerad och för båda personernas vinning. Tre hypoteser grundade på tre teorier om lögn ställdes. Varje hypotes angav en unik frekvensfördelning av val av kommunikationsmedel.
