The effects of self-efficacy on computer usage

1995

Abstract This paper examines the effect of self-efficacy, belief in one's capabilities of using a computer in the accomplishment of specific tasks, on computer usage. It introduces an extended technology acceptance model (TAM) that explicitly incorporates self-efficacy and its determinants (experience and organizational support) as factors affecting computer anxiety, perceived ease of use, perceived usefulness and the use of computer technology. A survey of 450 microcomputer users in Finland found strong support for the conceptual model. In accordance with TAM, perceived usefulness had a strong direct effect on usage, while perceived ease of use had indirect effect on usage through perceive…

Endringsledelse ved implementering av Enterprise Resource Planning systemer: en casestudie av praksis i ulike bedrifter

2012

Masteroppgave i informasjonssystemer- Universitetet i Agder, 2012 Ved innføring av ERP-systemer er endringsledelse ansett som en av de viktigste kritiske suksessfaktorene, men har likevel blitt tildelt for lite ressurser og oppmerksomhet. Selv om det er tekniske utfordringer ved en ERP-implementering, er en av de vanligste utfordringene knyttet til motstand fra brukerne. Mange ERP-implementeringer mislykkes som et resultat av et overdrevent fokus på de tekniske aspektene, noe som går på bekostning av endringsledelse og organisatoriske aspekter generelt. Denne masteroppgaven bygger på en kvalitativ studie hvor endringsledelse ved ERP-implementeringer i norske bedrifter har vært i fokus. Måle…

Evaluering av IKT-investeringer i norsk kommunal sektor ved hjelp av balansert målstyring: barrierer og fremmere

2009

Masteroppgave i informasjonssystemer- Universitetet i Agder 2009 Offentlig sektor har de siste årene gjennomgått en moderniseringsprosess med kjernemål som effektivisering, brukerretting og forenkling. Det kommer stadig krav om bedre og mer effektiv tjenesteyting uten at mer ressurser stilles til disposisjon. IKT fremstår som et av de viktigste virkemidlene i jobben mot disse målene og det viser seg at det budsjetteres en betydelig sum av kommuners totale budsjett til IKT. Samtidig er det mangel på dokumentasjon på uthenting av nytteverdier, omstilling og effektivisering ved introduksjon av ny teknologi. En viktig årsak for dette kan være mangel på formell evaluering av investeringene som b…

Cloud computing : en studie av muligheter og barrierer i det norske markedet

2011

Masteroppgave i informasjonssystemer- Universitetet i Agder 2011 I denne rapporten har jeg studert overordnede problemstillinger relatert til temaet Cloud Computing. Cloud Computing er en leveransemodell bestående av tre hovedkategorier Software as a Service (SaaS), Infrastructure as a Service (IaaS) og Platform as a Service (PaaS). Cloud Computing kan gi bedrifter muligheter for effektive og raske IT-løsninger uten større innvesteringer i maskinvare og programvare. Det eksisterer likevel en del problemstillinger og spørsmål relatert til Cloud Computing som gjør at det er interessant å studere om det faktisk vil komme et paradigmeskifte, eller om utfordringene ved å ta i bruk Cloud Computin…

Computational modeling in cognitive science: a manifesto for change.

2012

Computational modeling has long been one of the traditional pillars of cognitive science. Unfortunately, the computer models of cognition being developed today have not kept up with the enormous changes that have taken place in computer technology and, especially, in human-computer interfaces.  For all intents and purposes, modeling is still done today as it was 25, or even 35, years ago. Everyone still programs in his or her own favorite programming language, source code is rarely made available, accessibility of models to non-programming researchers is essentially non-existent, and even for other modelers, the profusion of source code in a multitude of programming languages, written witho…

Supporting fine-grained generative model-driven evolution

2010

Published version of an article in the journal: Software and Systems Modeling. Also available on SpringerLink:http://dx.doi.org/10.1007/s10270-009-0144-1 In the standard generative Model-driven Architecture (MDA), adapting the models of an existing system requires re-generation and restarting of that system. This is due to a strong separation between the modeling environment and the runtime environment. Certain current approaches remove this separation, allowing a system to be changed smoothly when the model changes. These approaches are, however, based on interpretation of modeling information rather than on generation, as in MDA. This paper describes an architecture that supports fine-gra…

Brukerinvolvering i ERP-implementeringer : raskeste vei til effektiv bruk av ERP-systemet?

2009

Masteroppgaver i informasjonssystemer- Universitetet i Agder 2009 Når en organisasjon går til det skrittet å implementere et så omfattende og komplekst system som det Enterprise Resource Planning‐systemer (ERP) er, så er det som alltid én gruppe av interessentene som sitter med minst makt. Denne gruppen er brukerne. Som bruker i en bedrift som implementerer ERP, opplever man mange omveltninger som ofte består i endrede arbeidsprosesser, nye rutiner i forhold til databruken, og svært mye nytt å lære seg for å være i stand til å utnytte det nye systemet så godt som det lar seg gjøre. Forskningen viser at dersom brukerne ikke lykkes i å henge med i denne prosessen, så vil det ha negative effek…

Accelerated Bayesian learning for decentralized two-armed bandit based decision making with applications to the Goore Game

2012

Published version of an article in the journal: Applied Intelligence. Also available from the publisher at: http://dx.doi.org/10.1007/s10489-012-0346-z The two-armed bandit problem is a classical optimization problem where a decision maker sequentially pulls one of two arms attached to a gambling machine, with each pull resulting in a random reward. The reward distributions are unknown, and thus, one must balance between exploiting existing knowledge about the arms, and obtaining new information. Bandit problems are particularly fascinating because a large class of real world problems, including routing, Quality of Service (QoS) control, game playing, and resource allocation, can be solved …

1996

The major new developments in electron crystallography and high resolution imaging of organic molecules are discussed. The aim is to show that the recent rapid advances in computer technology have made it possible to analyze molecules at a level or resolution which was impossible less than a decade ago, thus bringing the concept of molecular design to produce specific physical properties much nearer to realization

Collaborative Learning and Computer-Supported Collaborative Learning Environments

2008

A focus on purely individual cognition has set a stage to social construction of knowledge. New learning environments, in many cases supported by computer technology, are often based on collaborating and sharing expertise. As a result research on Computer Supported Collaborative learning (CSCL) environments is a significant and growing field, which actively seeks new methods to resolve the challenges of human learning across diverse levels of interaction in a modern information society. In this chapter we will discuss the concept of collaborative learning and the issues involved in using information and communication technology to support collaborative learning. We begin with the definition…
