Form och design i frisörutbildningen

This essays purpose is to accentuate the meaning of the knowledge of the design elements color, formand texture in the hair design education. Both the Bauhaus school and Pivot Point educationcampaign close knowledge in color, form and texture. In my study of the literature I compared theBauhaus school with Pivot Point International Inc, study material for hair design education. From thesimilarities in this material I develop a project in color, form and texture. This was a teaching test forstudents in the hair design education at the upper secondary.

Didaktiska effekter av begreppskonstruktion i ämnet Samhällskunskap : Hur två läroböcker framställer hållbar utveckling i relation till demokrati

The purpose of this essay is to explore how social media affect the political orientation and commitment of youths. Three scientific questions highlight the purpose from different angles. The didactic perspective is discussed in the initial and closing discussion, and is analyzed in the corresponding chapter. Two methods are involved in the study; one survey and one interview with a focus group. The survey had a total of 98 respondents from four different classes, all in the first grade of upper secondary school.

Metodval i projekteringsfasen : Bostadshus Ljusbojen 1

This major project in Building Engineering has its focus on inquiring into what methods has been used in the planning process of the residential buildingLjusbojen 1. This project has been conducted in cooperation with Kadesjös Ingenjörsbyrå AB, an engineering contractor firm which also acts as the property developer. Initially several different general methods for planning residential buildings have been presented. After the methods from the process of building Ljusbojen 1 has been analyzed compared to the general methods presented in part 1. This shows what the determining factors are during the planning process; factors such as cost, quality, time management, know-how and environmental issues.

Val av stommaterial : Vilket är det mest fördelaktiga stommaterialet vid uppförande av en hallbyggnad?

When constructing an industrial- or hall building, the most common framework materials thatis used are wood, steel or concrete. Due to an assignment from Byggnadstekniska Byrån ABhas a document been created that makes it possible to investigate how the final costs is af-fected by gapes in between elements and which used foundation. And this with steel as thematerial. The purpose with this essay is to investigate which is the most well fitted materialwhen constructing an industrial- or hall building wood, steel or concrete. Information aboutthe different materials has been collected by litterateurs and by different internet pages.

Att introducera ord : En studie i hur man kan presentera svåra/nya begrepp i läromedel för årskurs fyra

Elever i a?rskurs fyra har blivit sa?mre pa? att la?sa faktatexter (PIRLS 2011 i Skolverket 2012). Mitt bakgrundsarbete syftade till att underso?ka vad det skulle kunna bero pa? och resultatet tydde pa? att sva?ra/nya begrepp i framfo?r allt geografi och biologi skulle kunna vara en bidragande faktor. Sa? mitt examensarbete kom att bli en studie i hur man kan presentera sva?ra/nya begrepp i ett la?romedel fo?r a?rskurs fyra.Jag har samarbetat med Natur & Kultur och har da?rfo?r utga?tt ifra?n och arbetat med la?romedelsbo?ckerna PULS SO-boken Grundbok och PULS Geografi Sverige Grundbok.Jag har anva?nt mig av tre metoder och dessa a?r kvalitativ intervju, textanalys och litteraturstudier.

Läsinlärning : Hur kan processen organiseras?

The purpose of this paper is to examine how teachers choose to work with the teaching of reading and writing skills, how teachers justify their choice of teaching method and how the documentation of student development is being used. This paper also discusses the definition of reading and writing, phonological awareness and how different reading- and writing educational methods can be combined. The gathering of information has been done through a literature review in which I have looked at past research on reading and writing. I have also conducted qualitative interviews with teachers involved in literacy learning. The result of my research shows that it is not possible to determine which literacy learning methods that are most effective.

Den tolfte spelaren : En kvalitativ studie av hejarklacksjournalistik i den svenska sportjournalistiken.

This study aims to gain greater knowledge about the phenomenon cheerleading journalism and its existence in the Swedish sports journalism. We did this by making an impact in the media debate, to thereby identify key aspects of cheerleading journalism. These elements are then used to reach a preliminary definition of the phenomenon. This was followed by qualitative interviews with six Swedish sports journalists from newspapers Aftonbladet and Dagens Nyheter, with the aim to find out how they behaved the phenomenon. The results of the earlier debate and the answers from the respondents show that cheerleading journalism is nationalistic, biased and seeks an inclusive effect on its audience.

Att arbeta med ständig osäkerhet : En studie av High Reliability Organization

There are certain organizations that manage to handle risk in such a successful way that they almost stay error-free, in spite of the fact that they daily face the risks of accidents. These organizations are usually given the name High Reliability Organizations (HRO). While the most common example is that of a nuclear plant the variety of what organizations can fit into the category is extensive.The purpose of this study is to describe safety culture and theories about HRO and how these can be found in practise within an organization.This qualitative research uses influences of ethnography in its method. The ethnographical approach was picked due to the field of the study and the cultural context in which it is set.The results of the study identify a number of elements sorted into four themes. These themes are deemed compatible or non-compatible with relevant existing theories.

Säkert arbete

A film can attract all kinds of emotions and moods of the audience through its audiovisual communications and cinematic expression, in which music plays a significant role in both understanding and interpretation of film content.It is interesting to explore the musical significance and the emotional aspect of the film out of a media and communications perspective and visual communications perspective because it?s a subject that belongs to the communications of scientific discipline as film is a media text which is working both as communicative and as audio-visual medium with its expressive aspects.The purpose of this bachelor?s paper is to increase and deepen the understanding of music's function and significant role in context with its reinforcing sense of visual expression in film. More specifically, it aims to explore the musical value of the expressive aspect of the media text in form of film musical Les Misérables (2012), which has been transmedialised from the novel of the same name, referring to the sound, music and song in relation to the film's visual expression.The research questions are at the core of the essay study: "how is music used to reinforce the cinematic visual expression?" and "how can music signify the narrative and highlight the emotional aspect of the film?" The theoretical framework is based on some of the key scholars assumptions such as Michel Chion (1994) and Claudia Gorbman (1987), who share the same theoretical views that the soundtrack seems powerful when it expresses its participation in a scene?s emotional moods as the music follows the scene?s rhythm, the image?s flow and contributes emotional and musical codes of emotions and expressions. According to Chion sound and image interact together to tell a story where sound enrich the image with expressive and informative values.

Generationsskräpsamling med explicit kontroll av hårdvarucache

This report evaluates whether an interpreted high-level garbage collected language has enough information about its memory behaviour to make better cache decisions than modern general CPU hardware.With a generational garbage collector, depending on promotion algorithm and generation size, around 90% of all objects never leave the first generation. This report is based on the hypothesis that, because of the low promotion rate, accesses to higher generations are sufficiently rare not to benefit from caching.To test this hypothesis, we built an operating system with a Scheme interpreter in kernel mode, where the interpreter controls the cache. Generic x86 PC hardware was used, since it allows fine-grained control of cache decisions.Measurements of execution time in this interpreter show that disabling the cache for generations higher than the first does not give any performance gain, but rather a performance loss of up to 50%.We conclude that this interpreter design is not an improvement, but cannot conclude that the hypothesis is false in general. We suggest building a better CPU simulator to gather more data from which to make better caching decisions, moving internal interpreter data structures into the garbage collected heap and modifying the hardware to allow control in the currently rigid dimension of where data is cached---for example separate control of instruction and data caches and separate data caches for different areas of memory..

Quantitative thermal perception thresholds, comparison between methods

Skin temperature is detected through signals in unmyelinated C-fibers and thin myelinated A?-fibers in the peripheral and central nervous system. Disorders in thin nerve fibres are important and not rare but difficult to diagnose by the most common neurophysiological methods. In this pilot study different methods for quantitative sensory testing, QST, were compared to give some ideas about which method could be the most efficient to use in order to point out injuries of the sensory system in clinical practice. The comparison was made between Békésy (separate warmand cold thresholds) and Marstock test (combined warm and cold thresholds).

Sha Jun

The agriculture in Sweden today uses chemical substances to control vermin, weed and diseases. This usage shows through polluted subsoil water and trace elements in the food we eat. There?s a risk that additional symptoms will arise in the future. Our product Sha Jun, developed in 2006-2007, is an attempt to try and minimize the need of chemicals in the agriculture. The idea started with the attempt to minimize the usage of pesticides on the cropland.
