Naturens p?verkan p? elever i skolan: En forsknings?versikt ?ver hur biologiundervisning utomhus p?verkar elever med fokus p? intresse

In the Western world the interest in science in schools is steadily declining. Focusing on interest is important to encourage students to lifelong learning which is a written purpose of the Swedish curriculum. This literature study examines if biology education outside in nature could be a part of the solution for this problem and the question of issue is how can education outdoor enhance students? interest for biology and what other aspects does this effect simultaneously? The method of block search was selected for addressing this question, utilizing the ERIC and ERC databases. The results show that situational interest increased with outside education due to aspects such as: novelty, hands-on, knowledge acquisition and social interaction.

Förklaringsmodell för cykelresor i Trondheim : Fysiska och demografiska faktorers betydelse för det geografiska resmönstret

Habilitering av barn och ungdomar med dövblindhet

Aim: The aim of this study was to study through papers if early intervention of children and adolescents with deaf-blindness can be facilitated through early intervention programs, cochlear implants (CI) and communication strategies.Method: The method that we used was a literature study of scientific articles through Pubmed and Cinahl databases. The articles reference lists were also studied which lead to that more papers were found.Results: Children and adolescents with deaf-blindness can benefit from early intervention programs, when their caregivers were educated to give appropriate response to the children?s behavior. The interaction between children and their caregivers can improve through an early intervention model. Children and adolescents with Deafblindness have variable results from CI.

Molekylär klassificering av tjocktarmscancer : PAM-klusteranalys för identifiering av undergrupper

The main objective of this study is to divide a number of colorectal cancer cases into subgroups based on their molecular features using cluster analysis. The data used is supplied by a research group at Pathology, the Department of Medical Biosciences, Umeå University, and consists, after some preparation, of 455 observations which is a larger data set than many similar studies. The molecular variables that the clustering is based on are CIMP (CpG Island Methylator Phenotype), MSI (Micro Satellite Instability), BRAF- and KRAS-mutations. These are categorical variables and consequently the clustering method used is PAM (Partitioning Around Medoids) which is particularly useful with data on diverse variable level. The final analysis results in four subgroups that are represented by different combinations of attributes on the aforementioned variables.

Valsningsteknik för extremt höghållfasta tunna stål

New high strength steels require improved cold rolling techniques. The aim of this degree project was to develop a new and money saving cold rolling technique to manufacture steel strip for saw blades. The work is based on earlier rolling experiments made with a high carbon steel grade at LuCoil Steel AB. The work also focused on the mill requirements to cold roll high strength steels. The results show that LuCoil?s existing cold rolling mill was actually designed for rolling low carbon steel.

"Om jag är dålig jag slutar" : En studie av grammatiska avvikelser utifrån processbarhetsteorin i skönlitterär andraspråkssvenska

This thesis examines the way that subversivity is produced in relation to the name of the author, as understood by Foucault, and what potential for ressistance that can be glimpsed there. This from the reading of three text that in different ways relate to that theme.Firstly, throught the reading of "Isis mamma a?r genusvetare, skribent och konstna?r, min mamma a?r f.d. sta?derska, kokerska och dagisfro?ken, numera fo?rtidspensiona?r med diagnosen fibromyalgi" by Lidija Praizovic?, a text that actively work with the internal production of different exteriorities.

Den skeva bilden : En studie i hur brottsrapporteringen i Efterlyst ser ut jämfört med brottsstatistiken, samt hur programmets tittare upplever att de påverkas

The purpose of this thesis was to determine the tv-show Efterlyst?s (Wanted)effects on viewers when it comes to how crime, criminals and victims are portrayed in the show. In order to achieve the purpose of our the study, both  quantitative and  qualitative approaches were used We compared the image Efterlyst gives of crime, criminals and victims to statistical information from The Swedish National Council for Crime Prevention and The Central Bureau of Statistiscs. By using focus-groups we also studied how Efterlyst portrays, in the season of 2009, and how it may have affected its viewers. Our conclusion was that there are important differences between how Efterlyst portrays crime and the image of crime the statistics gives.

Felaktig alternativ splicing: Vissa mutationer i BRCA1, BRCA2, ER? och ER? är starkt förknippade med bröstcancer

Alternative splicing is a process that partly rejects the common definition of a gene ? that one gene codes for one specific protein. By variable combination of coding regions (exons) and exclusion of non-coding regions (introns), formation of several different mRNA-transcripts, and consequently several different proteins, can derive from the same gene. Alternative splicing is an important condition for the development of complex life forms, but it is also a highly sensitive process and inaccurate splicing is the cause of approximately 15 % of mutations that cause genetic diseases. This article presents four genes, BRCA1, BRCA2, ER? and ER?, and inaccurate splicing of these genes increases the risk of developing cancer, particularly breast cancer and ovarian cancer.

Dämpning av fläktljud i diskmaskin

Detta examensarbete omfattar akustiska undersökningar utav en desinficerande diskmaskin av typ Getinge 8666/8668 och har utförts på Getinge Desinfection AB i Växjö. Vi har undersökt hur man med enkla medel kan sänka ljudtrycksnivån i maskinens närhet. Mätningar har utförts på diskmaskinens torkprogram, där torkfläktarna är de mest dominerande ljudkällorna och ljudet främst är luftburet. En systematisk analysmetod bestående av införandet av successiva dämpningsåtgärder visade att de dominerande ljudvägarna går via taket, golvet samt till viss del spalter i maskinens väggar. Genom att isolera både tak, golv och spalter kunde ljudtrycksnivån sänkas med totalt hela 5,9 dB.

Kontorsskiftets påverkan på organisationskulturen : - Ett skifte från cellkontor till öppet kontor -

The essay discusses the effects that changes to the office plan have on organizational culture. Information about actual change as well as expected change in organizational culture was gathered before the empirical research was initiated. The empirical research was carried out at the Customer Logistics department at Ericsson through: an interview with a manager in charge of the relocation and design of the office, a manager for the specified department and also five employees of this department. The empirical studies show that there was a significant change in organizational culture and that results were not always as expected. There was a loss in symbolic actions, which needed to be compensated for, a perceived reduction in spontaneous communication, and a mixed response of perceived change in social interaction.

Med skrivandet som vapen: Strategier för motstånd i Buchi Emechetas författarskap

The purpose of this Master?s thesis is to examine the relationship between fiction and resistance from a postcolonial and feminist perspective. More specifically, the study is an examination of this relationship in ten novels by the Nigerian writer Buchi Emecheta. The resistance is studied by examining the way it is depicted in the texts, as well as whether the texts can be seen as a form of opposition. Both the resistance and its context are studied.

The Influence of Multiple Drivers on WOM Behavior in an Online Context - A quantitative study on what drives consumers to share word-of-mouth online

Word-of-mouth marketing (WOM) has been considered as one of the most effective marketing tools, yet the least understood. While its lucrative effects have been well proven in academic studies worldwide, little is yet known of why consumers engage in WOM, and what factors actually drive this sought-after behavior, particularly in an online context. While today's research lacks holistic views on the simultaneous effects of multiple WOM-drivers, this paper takes on a meta-analytic approach by building on the pertinent literature to construct an aggregated model, including several previously acknowledged drivers divided into two categories: (1) Brand related drivers and (2) Personal and situational drivers. The authors then empirically examine what drivers are the most influential on WOM in an online social media context. By doing so, this thesis does not only contribute to marketing managers' better understanding of online communications management, it also sheds light on the theoretical knowledge of the behavioral drivers of WOM.
