Ungdomar och datorn : Vilken roll spelar datorn i ungdomars liv?
How does the computer influence teenagers' lives. I interviewed five young people, and gave a questionnaire to another 47, about this.What I found was that they were aware of and handled well the risks with the Internet and the computer, but had problems with the computer taking too much of their time. They wanted more time for their families and outdoor activities. It was mainly the Internet that seemed to have an influence on the teenagers, not the computer as a machine. They told me that there was a rough climate on the Internet, partly because of the possibility of being anonymous.
Mellankrigstiden och Andra världskriget i gymnasieläroböcker i historia från 1944 - 2008 : en kvantitativ undersökning av innehåll och disposition
This essay investigates how the chapters of the interwar and the Second World War have changed in the high school history textbooks during the period from 1944 to 2008. In the study eleven history textbooks have been studied, most quantitatively but also qualitatively. For example the number of pages and rows devoted to different subjects and countries are compared in the books over time. The result of the study shows that there are some big changes over time but in most sections there are also big differences between the books, which make it harder to draw general conclusions. There are a lot more names, pictures and dates in the newer books compared to the older ones, although the number of different names is about the same in all the books.
Småhusproduktion : Utvecklingsmöjligheter hos JM AB
The Swedish building contractor JMRegion Öst would like to to investigatethe possibilities of developing andstreamlining the production of singlefamilyhouses. JM are producing singlefamilyhouses with prefabricated framesat a rate of about two houses per week.During construction, the different tasksare performed by JM?s own productionstaff but also by varioussubcontractors.When examining the schedules of recentlyproduced projects, it appears that allthe houses are more or less completedeight weeks before the customer moves into the house. During those eight weeksseveral operations are conducted such asinspections, installation of appliancesand cleaning procedures. The inspectionperiod constitutes between 25 and 35% ofthe complete construction period.By conducting interviews, it has beendiscovered that this final phase is anessential security buffer for delays anderrors that often occur.
Contortatallens roll för virkesförsörjningen på Holmen Skog, Region Iggesund : konsekvensanalys av fyra hushållningsstrategier för contortatall
Large areas of Lodgepole pine (Pinus contorta var. latifolia) were planted in the 1970s - and '80s. The purpose of the fast-growing species was to increase growth and with short rotation periods allow a rapidly increased harvest level. Today a large proportion of the young forests owned by Holmen Skog, Iggesund are covered by Lodgepole pine and an active forest management is required to spread the harvested volume over time which is desirable by a market perspective. The purpose of this essay is to investigate the possibility of spreading the harvested volume of Lodgepole pine over time.
Utveckling och applicering av en aviditets-ELISA för bovint respiratoriskt syncytialt virus :
Bovine Respiratory Syncytial Virus (BRSV) is a common cause of respiratory disease among young cattle. The virus causes severe losses; the herd mortality rate can sometimes be as high as 20 %. In this study the avidity (i.e the antigen binding force) of BRSV specific antibodies was measured to see if there was a difference between antibodies produced during an acute phase of infection and antibodies produced by earlier infected animals.
A commercially available ELISA-testkit against BRSV-specific antibodies was used and an incubation step with 6M urea was added. The effect of the urea is that it breaks the weak bonds between antibodies and antigen while the stronger bonds remain intact.
Four different groups of animals were included in this study; seven calves that were naturally infected, three acutely infected calves with known time of infection, five cows that were seropositive during several years and four experimentally infected calves that had been a part of a vaccine trial.
The results of this study showed that antibodies produced during the acute phase of an infection had a low avidity and that the avidity increased with time after infection.
Debatten kring Patriot Act. American Library Association's och den amerikanska regeringens förhållningssätt till anti-terrorismlagen The USA Patriot Act of 2001
This paper addresses the need to review the modern presentation of textile archaeology in museums. It is time to look at textiles in archaeology with new eyes. The reality behind archaeological textilestudy is holistic, embracing many different aspects of society. The presentation of textiles has in my opinion become old-fashioned. I will show in my paper that Jonathan Adams? `seven constraints´ model, developed for research on ancient ships, can also be applied to textile research.
Faktorer som påverkar barns läsutveckling
AbstractThe purpose of the study was to examine if manual signs used as support to spoken and written language can be a god mnemonic for learning of word-pictures. I performed my study as an experiment in which I made a Memory game with word-pictures. I played the game with the children twice. The first time, we played without manual signs and the second time I used sign as a support. I observed the children and noted the words they learned to read with and without the support of manual signs.
Logotypiskt : En studie om hur digitaliseringen harförändrat logotypers utseende
In this study we are seeking to discover the norms in the design of logotypes and how they havechanged over time. To achieve this we have chosen to analyze the logotypes of twenty companies withthe largest expenditure on advertising in Sweden. We mapped chosen design attributes within the logoto discover the similarities and then we selected the five oldest brands to analyze how their logos havechanged over time. The design changes in the logotypes over time is can be related to the changingattitudes of the general public and the designers ambitions to draw on convention to create iconic designthat will spark brand-recognition. However many changes can?t be directly explained through changesin convention.
Analytiker och riktkurser: - Varför bry sig?
The purpose of this master thesis is to evaluate how the current share price and market consensus affect security analysts target price and if an investor should pay any attention to it. Empirical data is primarily collected from qualitative interviews with ten security analysts but also from a quantitative e-mail survey. Our main finding is that security analysts are indeed affected by each others earnings forecasts as well as the current share price. This is not strange, it is in several aspects rational. Security analysts has often nothing to gain by standing out too much and not either by spending too much time trying to create their own opinions due to lack of time or the complexity of what is analyzed.
Utvärdering av ett silotorksystem för spannmål utrustat med omrörare :
The aim of this study was to evaluate the stir drying method, for drying of grain during Swedish conditions. The evaluation was done during the harvest year 2004, on four farms with stir driers. The driers were evaluated for their energy consumption, design, stirring effectiveness and how much time the farmer has to spend on every tonne of grain. A comparison was also done with conventional Swedish high temperature driers. Totaly six batches of grain from stir driers were examined, mostly winter wheat, but also barley and wheat.
Den vägda nyttjandeperioden och dess effekter på utvalda finansiella nyckeltal: En studie av bostadsrättsföreningars avskrivningstider på byggnader
Housing cooperatives in Sweden practice very long depreciation times for their buildings and assets, subsequently depreciation costs are very low. This study aims at addressing issues relating to potential upward revisions of these costs and the revenue levels needed by housing cooperatives to address these changes, while also providing a detailed summary of some chosen financial ratios under different circumstances. This study's results are based upon recent (2015) market data within the Stockholm region, collected through a manual process and analyzed quantitatively. On average, housing cooperatives EBIT do not cover their financial costs and have low profit margins. The average depreciation time is considerably above what a technical evaluation by other sources may state.

"Jag blev intresserad av matte" : Ett aktionsforskningsprojekt med formativ bedömning i matematik
This thesis examines the implications of a shorter intensive action research project on the formative assessments key strategies four and five that are activating learners as learning resources for one another and activating learners as owners of their own learning. The research questions were ?How do the pupils experience the formative approach?? ?What didactic consequences does the formative approach mean for the role of the teacher?? and ?How does the formative approach affects the pupils? results on a short term??. The results were that the majority of the pupils liked the approach and that they felt like their efficiency increased. The didactic consequences were that the teacher had to spend more time on evaluation but had more time during the lesson to listen to and discuss with the pupils. The pupils? results were not changed in comparison with the control group..
