VFU- en väg in i arbetslivet? : En kvalitativ studie som behandlar arbetsgivares värderingar av erfarenheter från verksamhetsförlagd utbildning.

The purpose of this study is to investigate whether the employability of newly graduated social workers is affected by the Supervised Practical Work Experience performed during the educational program. Four main questions were developed in order to establish an educated and concise theory: Does the newly graduated social worker?s choice of a specific Supervised Practical Work Experience affect their employability? Does the structure of the Supervised Practical Work Experience affect newly graduated social worker?s employability? What specific skills do employers within social work consider important for their organization? Is there a difference in how the representatives of various organizations within social work answer the aforementioned questions? The study was conducted through six qualitative semi-structured interviews. The people being interviewed work either as employers or recruiters in organizations from different areas within social work. Theories concerning organization and symbolic interactions were used during the analysis of the results.

Den bristfälliga implementeringen av LSS en studie av maktaspekten i mötet mellan socialtjänsten och människor med psykiska funktionshinder

In this study, the aim is to show how the social services fails to implement a specific rights law (LSS) wich is supposed to have the function of protecting the wellfare and provide specific rights to people with severe mental disabilities. By applying chritical theory on this case the aim is to provide an alternative answer on why it is possible for the social services to ignore these peoples rights.By revealing the power structures in the encounter between the system and a person with mental dissablilities, I conclude that people with mental disabilities does not fit in when it comes the social sevices way of implementing the law and further more that a private person is extreamly exposed to the systems arbitrariness..

Biosensorsystem fo?r o?vervakning av vattenkvalitet

Sweden's drinking water quality is considered to be high partly due to a high quality of the raw water and a well developed sewage infrastructure. Despite this, there is water contamination that could be prevented by installation of a sophisticated early warning system. Some of the major players in the production of drinking water have already invested in different types of early warning systems to ensure drinking water of high quality. There are various forms of early warning systems where automatic monitoring of E. Coli is an interesting alternative.

Alléers användning genom tiderna i Sverige : en bakgrund till alléns framtida utveckling

Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.

Motivations- och prestationshöjande undervisning för elever med autismspektrumdiagnos : användning av digitala verktyg i elevgrupper med autism och utvecklingsstörning

This is a study about how different digital instruments can be used in education for pupils with autism and intellectual disability. The questions formulated to research this chosen area was: ?What does teachers think about digital instruments and interactive teaching materials when it comes to benefits and disadvantages in the classroom?, ?In what ways is digital instruments used as teaching materials in the specific school context? and ?From a perspective of teaching and learning, what kind of problems and opportunities can be gained from using digital instruments and teaching materials?. To gather this information interviews was done with three specialist pedagogues working with the chosen group of pupils at three different schools. The material shows that the specialist pedagogues have positive attitudes towards working with digital instruments in this specific group of students..

Ytans djup : Visuell ikonicitet i den grafiska konstformen lyrik

This thesis revolves around an obvious fact: printed (or otherwise two- or three-dimensional) poetry is always and inevitably visual. By analysing a representative selection of poems, including conspicuously experimental and image-like poems as well as examples of more conventional poetry, the thesis points out that visual iconicity is an equally inevitable consequence of the visuality of printed poetry. The analysis applies terminology relating to iconicity and intermediality (presented by Lars Elleström, whose theoretical basis is the semiotics of Charles Sanders Peirce) to the selected poems, while avoiding making too specific interpretations, in order to maintain a discussion of the ever-present phenomenon of visual iconicity as such, and not just the individual examples.Rather than introducing visual iconicity specifically to confirm more or less specific interpretations of poetic texts, this method of approaching poems as two-dimensional works of art is what this paper mainly aims to propose, as a productive starting point for literary analyses in general; as is concluded in the theoretical framework by Elleström, the actual modal and iconic properties of printed poetry contradict mutually exclusive dichotomies such as verbal/visual and text/image. While indirectly visually iconic poems tend to have a wider range of possible interpretations at the outset, the existence of iconic potential, however, does not depend on any specific interpretation..

Pragmatisk förmåga hos barn med cochleaimplantat

A cochlear implant (CI) is a hearing device that makes it possible for individuals who are deaf or has a severe hearing impairment to receive auditory information and develop spoken language. The pragmatic ability may be affected. In short, pragmatics may be described as the study of language use in social contexts. Pragmatic ability can be seen as the result of the individual?s behavior as well as the underlying causes.The aim of the present study was to describe the pragmatic ability in children with CI.

Vattnet har gått! : En fallstudie av Karlstads kommuns vattenläcka 2011

Crisis communication in today's society is an important element for organizations. Whether an organization makes it through a crisis, good or bad is largely based on their crisis communication work. Crisis communication is about how the organization works to repair or maintain the organization's external image, the image that society has about the organization. When a crisis occurs stakeholders lose confidence in the organization or change their mind about it.This case study is about exploring how a municipality handles crisis communication through the various phases of a crisis. The study is also to examine how the municipality communicates with its stakeholders in specific communication channels during a crisis.The case study makes use of theories circulating crisis communication, such as: theories of how crisis communication should be handled, how a crisis is recognized, the different phases of a crisis, the communication channels that can be used and who may be interested in an organization when a crisis reveals itself.

Skaftslamkrypa (Elatine hexandra) i Bolmen, utbredning, tillväxt, reproduktion och styrande faktorer

The plants in the genus Elatine are characteristic for oligo and mesotrophic lakes. This study focuses on Elatine hexandra one of the four species in Sweden. It is stated as vulnerable by the National Environment Agency and a conservation plan with guidelines to preserve the plant in Sweden is under preparation. There have been a few previous studies investigating this plant in other countries but this is the first one for Sweden. The aim of this study was to investigate the distribution, growth and reproduction of E.

Aktivt system för tidvattenreglering av Lysekilsprojektets vågkraftsteknik

This report investigates a possible solution to the problem with adapting wave powerplants to work in countries with tidal water. The wire connecting the buoy at the surface with the generator at the bottom needs to adjust to the varying water depth. Our solution to this problem is to attach the wire to a jack which is then placed inside the buoy. The jack is then powered by an electric engine. The report discuss what forces the buoy will be exposed to and then the structural integrity of the design is evaluated through simulations.

Tvådimensionella rum

We are always surrounded by space, not just only in a room with four walls, but also when we are outdoors.Constantly we move in a flow of space that changes whenever we move. Unaware we are affectedby this threedimensional surrounding of ours, and it reacts with our perception. Many times, we chooseto translate it into something two-dimensional, for example when we take a photo, recording a movie orframing a view with a window. It helps us to catch a moment, a piece of reality and restore it in our ownway. In this project I?ve chosen to explore this process, to interpret and create my own theories about thistranslation from space to a two-dimensional surface.
