Korrektion och imitation som mätverktyg för diagnos av PT-nivå : Kan man korrigera eller imitera en grammatisk struktur som man inte kan producera i fri skriftlig produktion?

The purpose of this study was to examine whether a L2 learner could correct or imitate structures of the language that they could not produce in written production defined by processability theori levels.The Informants had Arabic as their mother tongue. The study showed that the ability of correction developed slower than the capacity for imitation and the ability to written production. The ability of the correction developed by the duration of the stay. The result was a confirmation of theory formation in processability theory. Corrective elicitering could be developed into a useful diagnostic tool in the classroom and thus provide an education that followed a natural learning order according to processability theory by Pienemann.Keywords: processability theori, imitation, correction, written production.

Förbränning av träpellets och pelleterad halm i en 40 kW rosterreaktor

The project focus on combustion of softwood pellets and pellets in a 40 kW grate fire reactor at TEC-Lab. Dept Applied Physics and Electronics at Umeå University. Experiments were performed at four primary airs to fuel ratios (0.7 to 1.3), where aspects such as temperature profile, levels of gases (CO and NO), sintering-/-slagging and unburned fraction of the ashes were studied. Four different fuel loads were used for wood pellets (10, 20 and 30 kW) and one fuel load for straw (10 kW). Combustion of straw proved very difficult to ignite, and also led to other combustion-related technical problem such as slag formation due to the relatively low melting temperature-/-slag temperature of the straw.

Mikroskopering av opaka faser - en studie från Skyttgruvan, Falun.

In nature there are about 4,500 minerals identified. These can roughly be divided into two groups, opaque phases and non-opaque phases, with the exception that some opaque phases also may act as a non-opaque phase in different circumstances. The division is made on the basis of the optical properties. Opaque phases are nontransparent, which means that a different type of microscope must be used. A conventional microscope uses transmitted light while the microscope for opaque phases or the ore microscope uses reflected light.

Överreaktion på aktiemarknaden - Myt eller verklighet?

PurposeThe purpose of this paper is to assess whether the overreaction found in ?Does the Stock Market Overreact?? by DeBondt and Thaler still persists today, and by equivalence test if a trading strategy based upon these assumptions would generate abnormal returns. MethodThe research has been carried out by studies of the stocks that for a prior period of one year has over or underperformed their benchmark. The stocks used in my study are all part of S&P500 index, and the period of study runs from three to five overlapping years over the last twenty years. ResultsMy tests indicate that the type of overreaction proposed by DeBondt & Thaler still is present, at least considering the stocks that during the formation period were winners..

Spelar språkresan roll? : Fyra individers upplevelser av språkresans betydelse för deras karriärval

The objective of the study is to examine whether the experience from language courses abroad has had any impact on the career choices for four individuals. Based on a qualitative research methodology, four semi-structured interviews have been executed. The two research questions have been answered by letting four people recount their experiences from language courses abroad linked to their self-images and career choices. The outcome is that the experiences from the language courses contributed to a more or less altered self-image. Most of all, the interpersonal abilities were fostered, which led to the formation of a self-image characterized by improved confidence in social settings.

Naturvetenskap och Bilderböcker : Naturvetenskaplig Begreppsbildning och Grundläggande Naturvetenskapliga Matoder

Preschool has a long tradition of using picture books, both as entertainment and as a resource for educational activities. In science there are two main application areas. The first one is science concepts and the second is to teach basic science process skills. These skills, observing, communicating, inferring, classifying, measuring and predicting reflects the methods used by scientists. Picture books potential to put science concepts and activities that promote the use of science process skills in a meaningful context, recommends using picture books for this purpose.

Bloggen - socialt medium med makt potential : En kvalitativ studie om konsumtionsideal bland svenska och internationella bloggar

Today, we live in a consumption society. We buy products to soothe our needs and desires. Thru material things we can express our own personal identity and shopping is seen more as a pleasure than a need to survive. With the background media- and communication studies, the reason of this study was to explore how blogs as a social medium can influence the consumption ideal in society. With dialogical analysis and semiotic analysis we wanted to see if we could find a specific consumption culture in the content of six blogs we did our studies on. We found that the blogs showed us that there is normal to have everyday luxury and spoil oneself with expensive things.

Hållning av kastrerade och icke kastrerade försöksmöss i par som en lösning på aggressivt beteende

Aggression between laboratory mice is a common problem and can result in welfare issues such as mice hurting or killing each other and also stress. Swedish laws and regulations clearly states that mice must be housed with a companion due to their natural social structure. Many studies have investigated the effect off enrichment, group size, cage size and other potential changes in in their environment on the occurrence of aggression. Even with these changes aggression can exist and therefore a new solution was tested in this paper. The proposed solution was to house an intact mouse with a castrated one and thus fulfill laws and regulations while still maintaining the physiology of one of the mice for the purpose of medical experiments.

Kvinnors behov av information i samband med Hysterektomi

Syftet med föreliggande systematiska litteraturstudie var att beskriva kvinnors behov av in-formation i samband med hysterektomi. Via Högskolan Dalarnas databas Elin och Blackwell Synergy söktes vetenskapliga fulltextartiklar som behandlade kvinnors informationsbehov vid livmoderoperation. Av 41 artiklar valdes 15 ut varav 8 kvantitativa och 7 kvalitativa. Dessa kvalitetsprövades med 28 kriterier från modifierade granskningsmallar efter Forsberg och Wengström (2003) samt Willman, Stoltz och Bahtsevani (2006). Av artikelurvalet framkom att kvinnorna saknade information om hysterektomi i allmänhet och i synnerhet om behand-lingsalternativ samt kvinnans gynekologiska hälsa och dessutom om post-operativ sexualitet.

Man vill ju veta vad som finns där ute... : En studie om unga människors val inför framtiden

I denna uppsats har jag valt att skriva om unga kvinnors tankar kring karriär, familjeliv och identitet. Dessa ämnen är saker som jag tror att de flesta upplever eller har upplevt att det finns många tankar och frågor kring, och jag vill genom min studie ge dessa kvinnors bild av hur man får livspusslet att gå ihop och hur tankar kring identitet, karriär och familjeliv kring detta kan se ut. Jag kommer att skriva om detta utifrån två synsätt, dels från det individuella planet, där jag utgår från mina intervjuer och berättar om mina informanters tankar, dels ur ett bredare perspektiv där jag sätter informanternas berättelser i ett större samanhang, men fokus på unga människors situation i Sverige..

"Jag är en individ och jag är också värd någonting" : röster om att ha varit föremål för ett tvångsomhändertagande som barn

Syftet med studien var att undersöka personers upplevelser av att ha varit tvångsomhändertagna enligt LVU som barn. Detta har genomförts med en kvalitativ ansats där fyra kvinnor intervjuades med stöd av en utarbetad intervjuguide. Denna täckte frågeområdena bemötande, skolgång, relationer och identitetsskapande. Resultaten tolkades utifrån livsmodellen, som är en del av den ekologiska systemteorin, samt utifrån kognitiv teori. De mest framträdande resultaten var att informanterna sällan känt sig hörda i utrednings- eller beslutssammanhang vilket medförde att deras åsikter sällan tagits i beaktande.

Nätverksdemokrati -vad bör, är, kan den vara

The main objective of the essay is to define the meaning of the termgovernance network on the basis of democratic values ? both normative andimperial - with the aim to analyse the prospects to develop an effective anddemocratic governance.
