This essay examines how four archaeology scholars reason about gender. I have used a qualitative method in making this study of their dissertations.  The aim is to obtain a deeper understanding of gender identity in prehistory, gaining a broader appreciation of how this might be expressed through archaeological material. This essay takes its theoretical departure from postprocessual thinking, where gender perspectives, including feminist and queer theories are in focus. The result of this study shows that the scholars have a postprocessual, structuralistic theoretical perspective in common, and that they use stereotypical identity-descriptions.

Tidigare forskning visar på att en prisvolatilitet existerar på marknaden för återvunnet material och att den många gånger är högre än volatiliteten för dess motsvarande jungfruliga material. Prisvolatilitet på marknaden för återvunnet material verkar vara en av orsakerna till osäkerhet på marknaden vilket i sin tur hämmar investeringar i marknaden, vilket leder till att färre substituerar jungfrulig råvara mot återvunnen råvara. Volatiliteten på återvunnet material kan ses från två olika perspektiv, ett där volatilitet är en orsak av effektiva marknader som styrs av utbud och efterfrågan och ett där volatilitet är en orsak av olika marknadsmisslyckanden. Syftet med denna studie är att mäta förändringen i volatiliteten för återvunnet material, utifrån ett antagande om att volatiliteten minskar över tiden då marknaderna för återvunnet material mognar och blir mer etablerade. Standardavvikelse används som mått för att mäta volatiliteten, där volatiliteten mäts för fem olika material, vilka har olika tidsperioder beroende på material.

Choosing a new plastic material for a container includes several different steps. In this case,the Finnish company Hackman needed a new type of packaging material for theircutlery- and kitchentool series »Hackman tools«. The project was carried out in cooperationwith the design agency Ytterborn & Fuentes, which has Hackman as a client.Several different demands were put on the material in order to fulfill as many of the clientswishes as possible. The most urgent problem with the existing container was the difficultysfor the customer to clearly see the contents in the container. Because of this problemthe customer tried to open the container in the shop.

Syftet med denna studie var att undersöka om och i så fall vilka laborativa material som används i samband med additionsalgoritmer med tiotalsövergång. Studien undersöker vidare de laborativa materialens betydelse för elevernas förståelse vid introduktionen av algoritmerna. För att ta reda på detta genomfördes observationer och intervjuer. Resultatet visade på att  laborativa material var vanligt förekommande. Det mest använda laborativa materialet hos de intervjuade lärarna var pengar.

This joint study has researched the use of non-European history in a Swedish textbook for the High School course History 1a1 as well as internet based material regarding the same issue. The aim of this study was to clarify the use of non-European history in regards to the Eurocentric theory.As for the textbook analysis the purpose was to research what non-European history was mentioned in the material with regards to geographical location and the events that were mentioned, as well as to study how much non-European history was included in the material compared to European or Western history.The study of internet based material aimed to show what kind of teaching material could be found on internet based databases by and for teachers. The study aimed to show how well the material handled non-European history, as well as to what degree the material used European perspectives when dealing with non-European events and geographical areas.In our thesis we have created our own definition of the theory regarding eurocentrism. The method used was a combination of a quantitative and a qualitative discourse analysis of the texts.Our results showed that the textbook was overwhelmingly Eurocentric, not only giving vastly more focus to the European parts of world history, but also using European perspectives and ideals to describe non-European events and areas. The internet based material, on the other hand, proved more diverse and less biased, but also more difficult to find and less plentiful.Our conclusion, then, is that teachers have to choose between the risk of letting their students develop a severely limited and heavily Eurocentric view of the world, and the additional workload required to find and organize non-textbook material to broaden their students horizons.We hope our study will contribute to the discussion of the place of Eurocentrism in today?s global and multicultural society..

I denna studie undersöker vi inomhusmiljö och material i två Montessoriförskolor. Våra frågeställningar handlar om hur inomhusmiljön är utformad och hur materialet är placerat i två Montessoriförskolor, samt hur två pedagoger i två Montessoriförskolor ser på miljö och material utifrån följande nyckelbegrepp från läroplanen för förskolan: utmaning och stimulans, initiativ och självständighet samt demokrati och medinflytande. I vår studie utgår vi främst från Maria Montessoris teorier angående miljö, material och självständighet, men tar också upp andra teorier kring miljö. Vi använder oss av observationer och kvalitativa intervjuer, som grundar sig på en pilotstudie som vi genomförde i en traditionell förskola. Resultatet visar på att miljön och materialet i de två Montessoriförskolorna tillåter barnen att ta egna initiativ och vara självständiga.

The intent with this paper is to investigate the medieval habitation in central Old Uppsala. This time-period has over the years been neglected. Therefore I wish to summarize and ana-lyze the medieval habitation to see what can be said about its continuity, and also to investi-gate why it is located in certain areas.Due to the amount of source material I have limited my investigation area to the central Old Uppsala. It is possible that this limitation will affect the result of the research but without the limitations the investigation area would have been too large to handle.The source material has been collected from excavation reports and the summarized. My theory is material culture and material agency.

The healing process of human bone can be aided by the presence of differentmaterials. A material that is transformed into bone when in contact with bone iscalled a boneconductive material. By transforming into bone the material reduces thetime that it takes to heal a fracture. This report is a study of existing boneconductivematerials on the market to see if there is a material available that would be suitable totest on larger fractures. The wanted application is to be able to heal fractures up to50 mm which is a fracture too big for the body to heal on its own.The healing process of human bone can be aided by the presence of differentmaterials.

The aim of this study is to find information about what to do when riding arena footings are worn-out. Especially, the surface layer of riding arena footings is very interesting because of its importance of giving grip in every step for the horse, as well as shock ab-sorption. Generally, surface layers are containing several different parts in order to achieve desirable properties. These different parts can consist of organic material or in-organic material (mostly gravel). Gravel and many other materials in the top-layer are environmental friendly, and therefore, easy to get rid of.

This essay studies the funnel-beaker ceramic in connection with the megalith graves in South Scandinavia. In my work I have described the nature of ceramics and looked on the crockery types and ornamentation and then discussed the use of the material in a ritual perspective. In the first part I have focused on the critical aspects you have to think about when you do a study like this one. In the second part of this essay I have done a case study, with the ceramic material, in three passages graves in the area of Falbygden, Western Sweden and studied the ceramic material and the nature of it in South Scandinavia as well. Then in the third I discussed the potential use, there is two, of the ceramic material in general of South Scandinavia and looked at it in a ritual perspective..

The purpose of this work is to investigate how 4-5 year olds perceptions of materials and material properties can be developed through an educational activity. The study is based on two interviews with eight children in that age category. The interviews were conducted before and after an activity where the children were first introduced to the subject by the tale of The three little pigs (Harris, 2009) and then given the opportunity to explore various materials related to the book. The kids got to experiment and explore how water affected materials and to compare different materials properties. The children were also attracted to build and create the material that was offered during the activity.

Detta examensarbete visar resultatet av en undersökning om hur språklärare i engelska, franska och tyska på gymnasieskolan använder sig av autentiskt material i undervisningen och hur de tror att detta påverkar eleverna.En kvalitativ forskningsmetod har använts och därefter har resultaten analyserats med ad hoc-metoden.Resultaten visade att nästan samtliga lärare blandade läroböcker och autentiskt material i sin undervisning för att ge variation. Den främsta anledningen till detta var att lärarna upplever att elevernas motivation ökar dåundervisningen varieras och om eleverna kan se en viss verklighetsanknytning. Vissa skillnader mellan språken påvisades, då engelsklärarna i större grad uppgav att de använde autentiskt material i undervisningen. Lärare ityska och franska menade oftare att brist på material och elevernas kunskapsnivå förhindrade arbetet med autentiskt material. Lärarna påpekade även att kursplanen inte hade någon påverkan gällande materialet, utan attdet var varje lärares beslut att ta..

When harvesteing ley there is always mechanical losses from the harvest machines.
