Lämna inte slumpen åt slumpen - En studie om hylloptimering i den digitala butiken

This paper examines the impact of conscious shelf management on online grocery stores. An S-O-R framework is used to unveil if some established shelf management techniques from physical stores are applicable in an online context. We also explain some of the cognitive processes customers experience as they get exposed to online buying situations. A main study with two data sources is conducted: one quantitative website experiment with 168 participants who got exposed to five different organisation patterns within five different categories; and one more qualitative eye tracking experiment with 20 participants. The results indicate that a disorganised product page evokes not only different scan paths and cognitive patterns but also generates higher sales.

Ergonomi vid armeringsarbeten : En studie om möjliga förbättringar i arbetsmiljön vid armeringsarbeten

Injuries and sick-leave is a common feature for reinforcement workers today. This is mainlydue to the fact that reinforcement work is done in an exposed environment with many stressfactors and highly repetitive work. These operations are often carried out in unsuitableworking positions, these positions creates a major burden on the bones and joints and causesmicro- damages on muscles. With repetitive work these injuries are not given time to healproperly and will gradually become worse.The body will not be able to handle the stress of working in a work environment such as thisand musculoskeletal disorders can be a result of this. The injury will make itself known aspain in the musculoskeletal system and causes reduced movability; the injured worker willtherefore not be able to perform the same work tasks as before.

Doktorander i fysik söker information : en intervjuundersökning av forskarens första tid som informationssökare

The aim of this Master's thesis is to examine difficulties concerning information acquisition, use, and management experienced by graduate students in physics during their first years of research work. Semi-structured, qualitative interviews were carried out with nine doctoral students. The theoretical background for analysis of the material is based on the work of Patrick Wilson, with particular focus on the concept of cognitive authority, and on that of Lars Seldén, who has proposed the idea of an information seeking career running parallel to the academic career of the researcher. Results from the interviews indicate that most of the students, in the early stages of their information seeking careers, rely to a great extent on supervisors and more experienced colleagues when identifying material needed for the research project. In a situation where information of potential relevance is abundant and where experience and focus are not yet fully developed, senior researchers function as cognitive authorities and as guides to other cognitive authorities.

KOGNITIV PROBLEMLÖSNING UNDER STRESS : PÅVERKAR FYSIOLOGISK AROUSAL PRESTATIONEN?

Förmågan att prestera under akut eller kraftig stress är en förutsättning för en del yrken. Forskningsresultaten gällande hur stress påverkar prestation pekar åt olika håll. Denna studie undersökte sambandet mellan fysiologisk arousal och kognitiv problemlösningsförmåga under stress. Trettiotvå polisstudenter testades på Ravens test av flytande intelligens APM set II både före och efter att antingen ha sprungit i tjugo minuter eller haft en självskyddslektion på ca fyrtio minuter. Resultaten från en mixed ANOVA för beroende mätningar visade på en signifikant interaktionseffekt (F (30) = 6,547, p < 0,05) ? en ökning i prestationen hos självskyddsgruppen med arton procent och en minskning med femton procent hos löpningsgruppen.

Aspergers, andar och böner till Gud : En fallstudie om Aspergers syndrom, religion och andlighet

This case study examined what impact the neurological disorder Asperger?s syndrome has on the line of reasoning about religion and spirituality. Also, the question of whether the four informants showed any tendency to use the cognitive tools calledtheory of mind (ToM), existential theory of mind (EToM) and hypersensitive agency detection device (HADD) or not was put forth. From the interviews five themes were extracted: a stereoscopical view upon the world, thoughts on physical causality, prayer used as one-way communication, spiritual agency and intentionality, as well as existential and social questions. These themes were subsequently matched with theories on ToM, EToM and HADD.

Omvårdnad av den geriatriska hunden

Due to progresses constantly being made in veterinary medicine combined with increasing knowledge in pet owners, the dogs of today gets older than before. The population of geriatric dogs is there for constantly growing, which makes them an important group of patients on small animal clinics and hospitals. As dogs age, so do their interior organs. Geriatric dogs are prone to several diseases and in this text the author has decided to focus on three of the most common: Cognitive Dysfunction Syndrome (CDS), cancer and osteoarthritis (AO). All of these illnesses are incurable in dogs, but it is important to remember that they are still treatable.

Språkliga och kognitiva förmågor hos barn med läs-och skrivsvårigheter : En jämförelse med barn med cochleaimplantat

Children with Reading and Writing Difficulties and Their Language and Cognitive AbilitiesA Comparison with Children with a Cochlear ImplantAbstractThe aim of this study was to examine the cognitive abilities that are important for reading in children with reading disabilities, children with a cochlear implantation and typically developed children. 64 children aged 10-12 years participated in the study. To answer the question at issue we used the following tests: Block Design from WISC III, PPVT III, TOWRE, SL 40 and a few chosen tests out of the SIPS battery. On tests of the lexical access children with reading disabilities performed at the same level as hearing children, while the children with a cochlear implant performed significantly lower. Test of the phonological and complex working memory showed that children with reading disabilities performed significantly higher than children with a cochlear implant, but at the same time lower than typically developed children on the test of phonological working memory.

Ny betygsskala- för elevernas bästa?

This essay is a study of the government bills for a new grading scale in the Swedish schools. There have been many complaints about the current grading scale and the main problem seems to be that teachers are interpreting the criteria for certificates differently. There are two major challenges for Swedish teachers, one is how to interpret the criteria for certificates, the other one is the equality problem , students can not be sure of that two different teachers would give the same grades. The main point of the essay is to try to find out whether the new grading scale will solve this problem. To my help I have made an analysis of the bills of the Swedish government for the new grading scale.

Barn som vistas på kvinnohus : En fördjupning av Oasenmodellen som arbetsmetod

At the Women?s House in Örebro, a children?s project has started where the work method ?Oasen? [Oasis] model has been developed by two children?s educationists. The aim of this study is, with the ?Oasen? model as a starting point, to deepen the knowledge of (1) how to meet children?s central needs while staying at a Women?s House and (2) what the ?Oasen? model may contribute to the children. The theoretical framework consists of a cognitive approach to the progress of children experiencing domestic violence and a presentation of conceptions concerning children?s needs.

"Folk kan ju påstå vad fan som helst" : En studie om elevers källkritiska förmåga och skolbibliotekets roll

Purpose: This thesis aims to study how students in upper secondary school evaluate sources in their everyday school work and how the role of the school library and librarian officiate in this context.Methodology: A web questionnaire was conducted and 155 students from different schools, with or without school library and school librarian, participated. We coded and aggregated the questionnaires according to the strategies that are used when evaluating sources, identified by Francke, Sundin and Limberg. Cognitive authority, a theory by Patrick Wilson, was also a part of our analysis. Conclusions: The study shows that students use different strategies, separately or combined, as a way to evaluate sources. The teacher is regarded as a cognitive authority and is the main influence concerning source evaluation. It also shows that the role of school libraries and school librarians, in this context, seem to be non-existent.

Källkritik, kognitiv auktoritet och domänanalys: Värdering av trovärdighet

The object of this explorative theoretical study is to compare similarities in three perspectives for evaluation of credibility. The perspectives are the historical method source-criticism, cognitive authority and domain analysis. These perspectives, regarded as intellectual tools for critical thinking in a process of information seeking, by asking questions about credibility related to the social and theoretical context of the intellectual background, can give support in articulating which documents that gives a specific and essential answer to a question. In this sense credibility is seen as a qualitative aspect of relevance. Patrick Wilson argues that we can attain some critical independence towards cognitive authorities and the literature by investigating the social and theoretical topography of a field.

ACTA : Utvärdering av tabell över kognitiva krav (CDT)

För att utvärdera en metod för tillämpad kognitiv uppgiftsanalys, ACTA (Applied Cognitive Task Analysis), har anställda på Saab AB genomfört ACTA genom att intervjua flygförare. ACTA består av tre intervjutekniker och skapades av Klein Associates Inc. ACTA är en metod som kan användas i tillämpade sammanhang för att ta fram aspekter av experters beslutsfattande. Denna rapport redovisar en utvärdering av CDT (Cognitive Demands Table), vilket är tabeller över kognitiva krav sammanställda av datamängden insamlad i intervjuerna. Utvärderingens syfte var att avgöra huruvida praktiker kan sammanställa en CDT med högt innehåll av kognitiva poster.

Performance of laying hens in a cognitive bias task : effect of time since change of environment

In the debate on laying hen welfare, and specifically housing conditions, the main focushas been on physiological and behavioural measures. What is lacking is knowledge of howthe hen experiences the situation ? her state of mind.This study is an attempt to gain insight into the private mental states of former batteryhens. It uses a cognitive bias method based on spatial judgement, i.e. judgement of aambiguous stimulus placed spatially in between a reinforced and an unreinforced stimulus.This method has previously shown differences in judgement by animals in enriched versuspoor housing.

Skolmognad utifrån förskollärares perspektiv

Preschool belongs to Lpo-94. School readiness can interprets in different kind of aspects, then you can not found any goals to reach in Lpo- 94 for the pre-school, which preschool teachers can relay to. There are comprehensive goals for the nine-year school in Lpo- 94, about which knowledge the student should have for the fifth grade. Purpose of the studie is to examine preschool teachers understanding of the phenomenon school readiness. Qualitative interviews by preschool teachers in south and middle of Sweden has been carried out and a hermeneutic analyse has been used for a deeper understanding of pre-school teachers interprets of school readiness.
