Hur uppnås användbarhet? En studie av ett system vid Landstinget i Östergötland

När ett system införs, spelar det ingen roll hur god funktionalitet det har, om användarna av någon anledning inte kan eller vill använda det på ett effektivt sätt. I första hand bestäms användbarheten hos ett program av egenskaper hos detta och hos de aktuella användarna. God användbarhet beror av acceptans från användarna, kompetens hos användarna och användarvänlighet hos systemet.För att undersöka hur man kan uppnå hög användbarhet och därmed en hög grad av användande vid införande av ett nytt system, har vi gjort en undersökning av användbarheten och användandet av ett system vid Landstinget i Östergötland.Våra slutsatser visar på att utbildning och information är mycket viktiga faktorer för att uppnå hög användbarhet för ett system. Många har en motvilja mot att använda datorer och problem med att se vilka fördelar ett införande av ett nytt system kan medföra, något vi anser kan lösas med bättre utbildning och information. Trots att teorier om användbarhet funnits i över tio år, har vi funnit att det forfarande inte tas tillräcklig hänsyn till de grundläggande faktorer som påverkar användbarheten vid införande av ett system..

Lägesuppfattning vid en svensk stridsvagnspluton

Abstract: After their introduction, technical systems designed for Situational Awareness have changed the possibilities on the battlefield. Today, Swedish tanks use a system known as the TCCS. This system offers many advantages to a tank platoon, but does it also bring disadvantages? This essay examines pros and cons with the TCCS. To find these the author uses a Swedish Armed Forces analyze model in a comparative study.

Protected Designation of Origin, Protected Geographical Indication : their significance for the growth of the food industries in France and Sweden

Protected Designation of Origin (PDO) is a quality control system created by the European Union (EU) to protect integrity of certain food and drinks that are produced in a specific area in a unique way. By protecting these products, the EU can certify that the traditional region-specific methods of food and drink production are preserved. The EU countries that follow such a system are mostly from Southern Europe. For instance in France, the PDO system has helped improve the income for farmers, boosted the rural development and assured protection for farmers against the abuse of their brand and the selling of their products by outsiders. In Sweden, there are no PDO products yet, instead there is Protected Geographical Indication (PGI) and Traditional Speciality Guarantee (TSG) that are not as protective as PDO.

Det ideologiska budskapet om integration : En innehållsanalys av riksdagspartiernas samt Sverigedemokraternas partiprogram

The aim with this paper is to study how the integrational ideology of the Swedish parliaments party platforms, including the right wing Sverigedemokraterna, is formulated. The integration theories examined are assimilationism, multiculturalism, universalism and residualism. In turn these theories are simultaneously applied to the party platforms extracting explicit or implicit messages of the four former mentioned theories. The Swedish history of integration as well as immigration, which per capita is one of the highest in the European union, pinpoints the reason why this subject is due to further investigation. The results show that most of the parties contain traces of more than one integration theory, with the exception of primarily Sverigedemokraterna which focuses on assimilationism.

Mellan säkerhet och mänskliga rättigheter : en studie av den svenska officiella migrationsdiskursen

This paper focuses on the Swedish migration discourse and investigates if and to what extent it is dominated by a security perspective. Analysing a number of official texts and documents I want to show how the discourse describes migrants and what implications this carries with it for the migrants and for the Swedish migration politics. Through discourse analysis I have analysed whose security that is prioritised, the Swedish or the refugees, who is the refugee and the asylum seeker, and who is the illegal migrant in the Swedish official migration discourse. As a theoretical frame for the analysis I have used theories on migration and security. These include theories on the securitisation of politics, the globalisation and the creation of political identity from the nation state perspective and theories on the connection between migration and security.My results show that a security discourse is dominating the Swedish official migration discourse and is therefore defining our reality and the identities of refugees, asylum seekers and illegal migrants.

Modell och analysverktyg för beräkningav frekvensförlopp

The power system modelled in this thesis work has been developed for simulationwhen e.g. the production in some part of the power system is changed. The powersystem has been modelled according to the swing mass of the system, the frequencydependency of the load and the turbine governor. The model determines the systemfrequency, the period of regulation and the power exchange between the differentsubsystems in the Nordic synchronized system.In this model the system frequency is assumed to be the same in all different parts ofthe power system and the voltage conditions in the power system are neglected. Forthat reason power swings does not occur between different subsystems in the powersystem, which usually occur as a result of the swinging connection between thetransmissions line.

Arbetsmiljöarbete enligt OHSAS 18001 : En inledande undersökning

There are regulations in sweden that require organizations to manage occupational,  health and safetey (OH&S) issues in a systematic way. The contents of the management system vary depending of the activity of the specific organisation. An accurate management system is crucial in order to assure that rules and regulations are fullfilled. The OHSAS 18001 standard covering OH&S management is intended to provide organizations with the elements of an efficient OH&S management system. The work with this thesis was done at Swemat AB in Härnösand wich is a mechanical industry. In the thesis, the requirements of the OHSAS standard are compared with the current management system.

Tillbakablickande nationalism ett minne blott? En teorikritisk fallstudie om nationalism och identitet i Hong Kong

In this thesis I have criticized traditional nationalism theories formulated by Eric Hobsbawm, Ernest Gellner, Benedict Anderson and Anthony D. Smith. The critique has been based on my belief that nationalism theories do not explain nations whose foundation is built on forward-looking, dynamic aspects such as economy, human and civil rights, and democracy. Traditional nationalism theories have been focused on historicizing perspectives whereas I want to draw attention to non-historicizing perspectives within the field of research. So far nationalism theories has had a shared past or a shared ethnicity as its focal point.

Variationen i användandet av IT-verktyget Trade : En fallstudie hos NCC

Companies that are facing the global market are put in to new challenges in order to streamline its business. One industry that has realized that changes are necessary is the construction industry, it is an industry witch is far behind the development of introducing information technology-tools systems in there business. It has shown there is a relation between high IT usage and high productivity, which is one of the reasons to why companies in the construction industry should purchase a business system especially for procurement. However, companies that have purchased a business system are facing difficulties in having their employees using it for its purpose. People react differently to changes and that?s why variations in quantities exist for usage of information technology-tools.

LOST IN TRANSLATION: Kommunikation förlorad i informationssystem

This study investigates communication and data in information systems. The paper deals, more specificly, with communication in a CRM-system implemented in a Swedish-founded company in Beijing, China. It discusses cultural, political, linguistic and gender based dilemmas that can arise from the use of a CRM-system in an international and bilingual environment. Fifty-nine interviews were conducted in Sweden and in China, either in Swedish or English. The result of this study shows that communication in the information system is affected by factors, that are not originated in technical shortcomings of the system, but rather from cultural, political, linguistic and gender based pre-knowledge among individuals.

Universell kunskapsorganisation: identifiering av ett framväxande forskningsområde genom citeringsanalys.

An ongoing discussion concerning the possibilities of universal classification based on phenomena rather than on research disciplines has been noticed. In order to discover if this was a limited discussion or the beginning of a major new field of research a study of citations was made using the database Web of Science. In addition, references of the works concerned were studied to find out where the ideas originated. The study of references shows that the ideas originate in a limited number of older published works, some of them well established in Information Science, some of them less generally known. The main ideas commonly used in Information Science are Ranganathan?s facet theories and the work of the Classification Research Group.

Kalkylering i flygbranschen: En fallstudie av ett flygbolag

The purpose of this thesis is to analyse and propose improvements to the cost accounting system in use at an airline operating on the Swedish market. The choice of study object is based on the airline?s desire to have its cost accounting system evaluated. During the analysis we have identified a number of points where the current cost accounting system does not correspond to its intended purpose. These points include significant groups of costs not being considered in the current system, potential over capacity is not visible and logic connections between distribution keys and the use of resources are sometimes lacking.

"The history books tell it, they tell it so well" : Minoritetselever och historieundervisning i den svenska gymnasieskolan

The purpose of this study is to analyze different aspects of a portraying of individuals from a time past. It is concentrated around questions about why it is important to show the people?s stories in, for example, exhibitions and under which conditions this would serve as a good use of history according to different theories about history and the portraying of it.I have chosen the theories of Freidrich Nietzsche and Georg Simmel as a tool to analyze different aspects of the portraying of people from the past. Nietzsche?s theory about the different ways in which we use the past and Simmels theory about the meeting between a viewer and a cultural experience.
