Digitala och sociala medier i undervisningen för elevers ökade motivation, delaktighet och måluppfyllelse.

The aim of the study was to examine both 1) how aware teachers in a specific area are about ICT tools in teaching ; and 2) how likely teachers are to use ICT tools to reverse the trend of unmotivated students and low achievement scores . I will look for answers through the following questions:How extensive is the knowledge of the teachers on digital and social media in education? How have teachers in the past year used various social media in their teaching? In what grade does ICT-supported teaching lead to higher motivation, participation and achievement? Is there a difference between the sexes, different stages (1-3, 4-6, 7-9) and number of years in the profession in knowledge of and openness to the use of ICT in education?The method used is a questionnaire in which a number of respondents have answered a number of questions about ICT tools in teaching. Validity of the study can be said to be high when the survey has measured what it intended to measure, however, I need to be careful in draw full account of the result as the response rate is low with only 39%. In summary, the results show that there is low awareness among respondents about the methods and the digital and social tools I lift in the survey.Mainly the respondents use some of the methods and the digital and social tools in preparation for the lesson.

Wikipedia : Informationspublicering på Internet ur ett genus- och maktperspektiv

This essay is about publishing on the Internet and aims to understand the differences between publishing information on the webpage Wikipedia (Swedish version) in contrast to other information pages on the Internet, for example blog, discussion pages, homepages etcetera. The study is based upon an article which described that 90% of the information publishers at Wikipedia belongs to a small elite of white, western, well educated men between the age of thirty to thirtythree. This study examines why people who does not belong to this heteronormativity publish information in other Internet places but not at Wikipedia.Wikipedia is an open source site, where anyone can publish and are even encouraged to do so and is often described as an utopian dream of the digital democracy, so why don´t people express themselves on Wikipedia? The method is based on two discussion groups, which are compared and analyzed. The study is based upon theoretical competence within feminist theory and conceptions such as intersectionality, heteronormativity and digital divide as well as theories about digital devices and social order.

Digital mediehantering i Försvarsmakten

Det senaste året har jag arbeta med analys av digital mediehantering, digital media som ett informationsverktyg samt tekniken bakom det. ?Hur kan man göra saker mer effektivt?, ?är webb-tv något för Försvarsmakten att använda sig av i syfte att göra sitt informationsflöde mer effektivt?, både internt och mot allmänheten. Föreliggande arbete tar upp tekniken bakom dessa områden, jag försöker även förklara hur relativt enkelt det kan vara att integrera dem i en existerande organisation utan att göra dyra omorganisationer. Jag har även inventerat AMF och FM media på deras utrustning, teknik och gjort en lista på vad som är användbart och på vad som bör tas bort inför en omstrukturering. Vidare föreslår jag var en viss utrustning bör lämpligast placeras för att göra mest nytta. Slutligen handlar detta arbete om att skapa en medvetenhet om digital media, och visa exempel på vad man kan göra med denna teknik i en organisation som Försvarsmakten och AMF..

Individuell mätning av hushållsavfall i flerbostadshus : ?Ett incitament för minskad klimatpåverkan?

The electric vehicle market has potential to contribute to Sweden?s national goal to have a fossil fuel independent transport sector by 2030. However, the market answers to a lot of challenges making it difficult for the market to fully reach its potential. The volume of electric vehicles has seen a steady increase during the last year (2012), although many of these vehicles are mostly for PR purposes or bought by the public sector that wants to lead by example. Still, barriers in the form of high purchase costs, an anxiety for the limited battery capacity and the lack of standardisation are some of the problems that the market is struggling to solve.

Att studera validerade mätinstrument : för att mäta barns oro inför dagoperation

Background: Anxiety with children before surgery is well known. From the 1950s there are various assessment instruments. Despite that most day surgery units offer preparation for children and parents, there are many children who exhibit a strong anxiety the day of surgery, which can lead to postoperative behavioral changes. Today the nurse estimates the anxiety of a child on personal experience and knowledge, forming the basis for estimation whether the child is in need of sedation or not. The purpose: of this study was to evaluate instruments that the nurse can use in measuring the degree of anxiety of children before fast clinical settings, such as day surgery.

Digital-TV : Hur digital-TV-distributörer bygger relationer med kunder

1997 kom riksdagen med ett förslag om att genomföra ett teknikskifte inom Sveriges marksända TV-distribution. Teknikskiftet skulle innebära att de analoga TV-sändningarna via marknätet skulle ersättas med digitala TV-sändningar och övergången skulle därför bidra med en mängd ekonomiska och tekniska fördelar. Digital-TV-sändningar erbjöds sedan tidigare av ett fåtal TV-distributörer men skulle nu bli något som fler TV-konsumenter skulle få tillgång till.Digital-TV-övergången är nu i full gång och påverkar såväl konsumenter som distributörer av digital-TV produkter och tjänster. Syftet med uppsatsen är att undersöka hur två digital-TV-distributörer anpassar sin marknadsföring för att stärka relationer till befintliga kunder och skapa relationer till nya kunder. Uppsatsen fokuserar på huruvida distributörerna tillämpar transaktionsmarknadsföring eller relationsmarknadsföring och hur den rådande digital-TV-övergången påverkar marknadsföringen.Teorier bakom relationsmarknadsföring fokuserar bland annat på relationen mellan leverantör och kund och detta är det centrala temat i uppsatsen.

Gäddan & fisket i Ringsjöholm : en osteologisk metodstudie i säsong & bevarande

This paper presents the results from an osteological method study of the Ringsjöholm fishbone material. Ringsjöholm is located in Scania, southern Sweden and is 14C dated to 5960-5200 B.P. The aim of this paper is to critically analyse methods used on fish bone material in estimations of season. Three different approaches were used to estimate the fishing season at the Ringsjöholm settlement; 1) identified species, 2) size estimations of the pike based on Enghoffs (1994-95) regression formulae of os dentale, and 3) growth rings of the pike vertebrae.The identified species and the size estimations of the pike points to the fishing being active both during spring and summer. Growth rings analysis of the pike vertebrae didn?t give any quantitative results because of fragmentation.

Mikrolitografi för rastrerade Gobos

Beacon AB has been producing Gobos for some time. A Gobo is a small round sheet used in projectors almost like a slide. It is used mostly in the commercial and entertainment business. Today these Gobos are created by using a film (also called mask). A digital exposure machine called LIOS has been developed to make it possible to create Gobos using direct exposure.

Arbetsledarens uppfattning om inhyrd personal respektive fast anställda : Skillnader och likheter i arbetsförhållanden och relationen till arbetsledaren

Efter avregleringen av lagarna under 1990-talet öppnas marknaden med uthyrning av personal. Bemanningsföretag anställer arbetstagare som därefter hyrs ut till kundföretag som strävar efter högre flexibilitet i schemaläggningen av arbete. Finns det ingen efterfrågan av arbete blir dessa anställda utan sysselsättning trots att de har anställning i ett bemanningsföretag. Syftet är att beskriva och förklara arbetsledarnas uppfattning om inhyrd personal respektive fast anställda vad gäller arbetsförhållanden och relationen till arbetsledaren. Uppsatsen är utförd som en flerfallsstudie byggd på intervjuer med arbetsledare i företagen Coca-Cola Drycker Sverige AB, Posten Logistik AB, Schenker Logistics AB och Spendrups Bryggeri AB.

Digital tomosyntes vid lungröntgen

Lungröntgen är en av de vanligaste röntgenundersökningar som görs i Sverige. Många gånger vid vanlig lungröntgen kan patologiska förändringar bara misstänkas så då används datortomografi (CT) undersökning av thorax som komplettering. Detta ger en ganska hög stråldos till patienten. En ny teknik, digital tomosyntes har visat sig kunna ge klart bättremöjligheter att ställa diagnos vid flera sjukdomstillstånd än vanlig lungröntgen utan att ge anmärkningsvärd högre stråldos. Några studier har visat att behovet av CT undersökningar kan reduceras med hjälp av denna teknik, vilket ger klart lägre stråldos till patienten.

En bild ljuger aldrig? : En studie om digitaliseringens inverkan på trovärdigheten i fotografier

The concept of the photographic truth has had a special status for almost 200 years. Yet with the emerge of digital technology and especially digital photography there has been a loss of the particular connection photography has had in reference to reality. The aim of this study is to see in what ways digitalization has affected the credibility of photography from the perspective of professionals in the field of photography. The digital technology that has enabled the large-scale manipulation of photographies is not, however, the main reason for the decreased credibility of photography. The ongoing discussion about the available possibilities concerning digital imagery and manipulation has had a far more powerful effect on the concept of the photographic truth.

Politisk styrning för ökad digital delaktighet : Aspekter av "governance" och "government"

Bachelor thesis in political science by Malin Bergkvist, autumn 12.Title:Political governance for increased digital inclusion.Subtitle: Aspects of "governance" and "government".Supervisor: Joachim Åström. While digital inclusion is a hot topic in both academia and in policy circles, little research is done when it comes to governance issues. To help filling this gap, this essay asks which mode of governance is dominant in the field of digital inclusion. What aspects of governance "governance" or "government" is the dominant in the field of digital inclusion, and is it possible to see any difference in how the state governance is described by the government and perceived by other actors? To answer this overarching question, two sub queries are formulated and analyzed. First, what aspect of "governance" or "government" dominate when state governance of the area are examined based on how the government describes it? Second, what aspect of "governance" or "government? dominate when state governance are studied based on how the perceived by other actors and stakeholders active in the field.

Förutsättningarna för ett parallellt generation IV system vid svensk nybyggnation av kärnkraft.

A new build in the Swedish nuclear power system would entail increased re-quirements for the proposed repository, which is adapted after the reactors of today. With a fast reactor, capable of burning nuclear waste, operating in parallel with the light water reactors, the increased requirements on the repository could be reduced.In this thesis, simulations of a light water reactor and a fast reactor have been performed by using the Monte Carlo code Serpent to investigate the changes in the fuel inventory. The light water reactor in the study is a boiling water reactor and the fast reactor of the type sodium-cooled fast reactor and they have been used for three different operation scenarios.By studying the fuel composition and the results from the simulations of the three scenarios conclusions can be drawn. Conclusions regarding the change of the fuel inventory and decay heat in Clab as well as the interim storage facility and in the repository. Depending on the operation alternative the changes dif-fered significantly and especially regarding the mass of burned actinides for different fuels in the fast reactor.The lowest increase of fuel assemblies was meet when using 50 years old fuel with 20MWd/kg U burnout and 2,0 % enrichment for start up of the fast reactor and 30 years old fuel assemblies with 50MWd/kg U burnout and 4,7 % enrichment for the further operation of the reactor.The increase of the number of fuel assemblies was 3174, which is equivalent to 641tons of heavy metal.
