Pedagogers arbetsmetoder kring elever med dyslexi : en kvalitativ studie av pedagogers syn på hur man arbetar med elever med dyslexi

Dyslexia is a disability faced by an extensive amount of students in the current educational system. No medical alternatives have been found to improve the cognitive processing challenges presented with dyslexia. Therefore today?s educators are required to make instructional adjustments in their schooling, to ensure dyslexic students an academic future. The purpose of this qualitative study was, firstly, to discover how teachers work with dyslexic students, and secondly, to find out which practices are being used in this field.

Framtagning av ett nytt recept för clear-coat batter av pommes frites : En teknisk och sensorisk utvärdering

The requirements of good quality and appetizing fast food increases continuously as a consequence of a community where food is always available. The crispiness of French fries is an issue that must be considered in this context, since it tends to decrease and give the fries a soft surface not appreciated by the consumer. To prolong the crispiness, the fries can be coated by a batter, a mix of starches. The batters used often consists of modified starches, e.g. cross-linked, acetylated and dextrinizated to increase and prolong crispiness, flour to stabilize the batter and sodium bicarbonate to make the batter ?rise?.The cross-linked starch keeps the granules in a swelled state and prevents them from breaking when exposed to heat or processing: therefore, it delays the gelatinization and decreases the stickiness of the batter.

Folk och land hör nära samman : En analys av stil, politisk berättelse och normalisering i Sverigedemokraternas partiprogram

This thesis in Art History and Visual Science is about values to graffiti and graffiti artist Banksy. I have studied values relating to Banksy´s graffiti images through which context they are placed in and where they are located. I have selected two different images of Banksy as an example on the basis of a transnational phenomenon, where the images that circulate in the public arena by street art and other images and imported into the galleries and consumption market. My conclusion is that the values of the images are based on the context in which each room have its surroundings and that therefore the impression will increase. The public space context, signal availability and the white cube context indicates art, and the commercial context signals goods and items that can be bought.

Informativa strukturer och egenskaper som stöd för automatiska processer i människans informationshantering

The purpose of this thesis is to create opportunities for an efficient interchange of information between humans and technology, especially for the skilled user, and put the designprincipal for informative structures and features into practice. Informative structures and features in a large number of information items helps the peripheral visual system to automatically capture knowledge through logical patterns.A field experiment was done to evaluate if informative structures and features, implicate efficient human information-processing, even in a small study. The results was ambiguous because the quantitative part of the investigation didn?t show any significant differences, whereas the qualitative showed that people prefer a dynamic document with a high degree of informative structures and features over a dynamic document with a low degree of informative structures and features. Even if this study was inconsistent, probably because to few subjects where used, the implication of the research that?s behind it is solid.

Offer eller förövare? : En analys av Dagens Nyheters rapportering om mäns våld mot kvinnor under perioden 1994-2009.

The purpose of the study was to analyze how media, in this case, the daily newspaper Dagens Nyheter, produces the men and women in men's violence against women in close relationships in news articles and if there has been a change over time in this production. It is a qualitative study in which 40 news articles from DN were analyzed. The starting point in the tanks around the analysis is from a social constructive perspective. Critical discourse analysis is the method I chose to use in the processing of news stories.

Effektiv betong för småhusproduktion : Betong med högt luftinnehåll för platta på mark

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

SÄRSKILT BOENDE SOM MÖTESPLATS En studie av vardagliga relationer mellan personal och de boende

Abstract This essay is about the visibility of everyday life in a nursing home. The thesis is based on the following questions: What characterizes the social life and conversation between staff and residents? What content has the social life and the conversation between these parties? What is the power relationship between the staff and residents? To answer these questions, we used the qualitative approach with open observations, along with interviews. The study is partly based on direct observation by an observer as a participant in a special housing, and on semi-structured interviews with seven respondents, three of them staff and four residents in the same nursing home. For the results and analysis section, we use the Grounded Theory as a method which constructs a parallel between data processing and analysis of the interviews, where we first encode, categorize and create themes.

UTVECKLING AV EN KONDENSATORMIKROFON

Detta examensarbete har utförts på Örebro universitet och Västerdalarnas Mekaniska Industri AB (VMI) i Malung för Ehrlund Microphones.Ehrlund Microphones tillverkar mikrofoner med sin patenterade kapsel, som bland annat består utav ett triangulärt membran.Under examensarbetets tid var en ny mikrofonmodell under utveckling. Målet med examensarbetet var att bistå Ehrlund Microphones med utförandet av tester och mätningar, samt att komma med förslag till förbättringar på den nya konstruktionen.På VMI i Malung, där kapslarna tillverkas, finns ett mätlabb som är till för att mäta kapslarnas frekvenssvar. Mätutrustningen i detta labb har installerats och konfigurerats för den mätmetod som har tagits fram för att verifiera kapslarnas frekvensgång.Slutsatsen av undersökningen huruvida skyddsgallret påverkar mikrofonens frekvensgång, är att den volym luft som ryms innanför skyddsgallret har större betydelse för frekvensgången än vad den geometriska utformningen av gallret har.Med stor sannolikhet kommer den nya transistorbaserade mikrofonmodellen att ha ett bättre signal/brus-förhållande än vad som visas i detta arbete, eftersom testerna har utförts på en prototyp i utvecklingsskedet..

Påverkar suggors grymtande under digivningen smågrisarnas tillväxt? :

The pig is unique in the way that it gives birth to a large number of newborns in each litter. Because of this the sow has developed a special behaviour during suckling to ensure that not only a part of the litter gets all the milk. Milk is only available during milk letdown. The piglets have to massage the udder for a long time before letdown and the more piglets at the udder the sooner the milk comes. The sow has developed a special grunting pattern to let the piglets know when she is ready for suckling and to signal milk letdown. Our aim with this study was to investigate if sows have individual grunting patterns repeated over time. We also wanted to know if sows with a more distinct grunting pattern have better growth in their litters.

Stor problematik på liten yta : Att skriva informationsmaterial för skattefinansierade verksamheter

The purpose of this thesis has been about processing an already existing folder for a tax funded organization which is also the employer for this mission ? Expectrum. The reason is that both Expectrum themselves and the recievers of the folder are unhappy with the existing material. The critic that has been directed to Expectrum is that the recievers have trouble understanding what Expectrum is and what they do. Based on qualitative methods such as interviews and text analysis I?ve been able to answer my questions for this thesis.
