Matematiska färdigheter hos elever med lässvårigheter i årskurs 4

Reading difficulties is the most common learning difficulty in the western world and it is common that people with reading disabilities also exhibit arithmetic difficulties. Different theories about the cause of the relationship exists, one theory describes the importance of good phonological ability in reading as well as in arithmetic, while another theory describes the importance of a reliable number system and that only a subgroup of students with reading disabilities also have difficulties with arithmetic. The purpose of this study is to investigate how students with reading difficulties (RD), without any known mathematical difficulties, perform on mathematical tasks relative to a control group. The study was theoretically grounded on the Triple code model (Dehaene, 1992), which is a model for numerical information processing that describes how various numerical and arithmetic tasks are processed through three distinct representation systems in the brain, a verbal and a visual representation system and a quantity system. Reading skills, phonological skills, arithmetic skills and number processing skills were examined in 61 students through a variety of tests.

Kommunikation mellan två medium

The aim of this project is to find a concept solution for a wireless transmitting system, installed to transmit data from a hydrophone of the ocean floor down by a wave power generator to the office on shore. The project is a literature review in which previous observations and tests are analyzed and put together to find a solution. The result was a comprehensive solution that includes an acoustic modem to transfer captured information from the bottom to the surface, wirelessly through the water. The information is then sent fron the surface on radio waves through the GSM network to the office on land. Between under and over water there are components to convert information between acoustic waves and radio waves, but also various types of modulation, such as amplitude and frequency modulation is required..

Lucid dreaming treatment och lucida drömmars relation till locus of control, depression samt subjektivt välbefinnande

Lucida drömmar (LD) innebär att drömmaren inser, under drömmens gång, att omgivningen och händelserna runtomkring är en dröm och inger förmågan att kunna påverka och reflektera över händelserna i drömmen. I lucid dreaming treatment (LDT) får drömmaren lära sig att förändra mardrömmars händelseförlopp. Dock blir inte alla lucida och många tror att det är själva känslan av kontroll som ger en effekt. Studien kommer utforska om kontroll utgör en nyckelkomponent i LDT genom att undersöka sambandet mellan LD och locus of control (LoC), depression och subjektivt välbefinnande där LD verkar som en medierande variabel mellan å ena sidan LoC och å andra sidan depression samt subjektivt välbefinnande. Deltagarna (n = 54) i undersökningen har fyllt i formulär gällande frekvens av drömmar och LD samt formulären Rotter?s 29 item internal-external scale, Center for epidemiologic studies depression scale, International positive and negative affect schedule short form, Satisfaction with life scale och Pittsburgh sleep quality index.

Framtidens lagefterlevnadsverktyg hos små och medelstora företag : en behovsanalys

This thesis aims to investigate what requirements companies have in order to achieve a successful legislative compliance control. The implementation of an environmental management system can help the company to structure their business and succeed with their environmental legislative compliance.Both small and medium sized businesses perceive that it is difficult and time consuming because the legislation can be difficult to interpret if you do not have the required knowledge. There are many companies that hire help in the form of consultants who audit their compliance, but this leads to a risk that the company will be exposed when the knowledge does not remain in the company if the consultant would cancel the cooperation. There are not so many tools today for businesses to obtain good legal compliance. The methods used are usually checklists included in the control program, and it costs a lot of resources to do everything needed.This study strives to deliver the expressed needs of the businesses.
