We have analyzed if the teachers sees ICT as a burden or a resource in their education and also in which extend they have digital literacy. We have chosen to discuss different authors view on ICT in the education and digital literacy.

Systematisk riskexponering i svenska hedgefonder: Svenska hedgefonders exponering mot riskfaktorerna i Fung & Hsieh (2004) under perioden 2006-2007
This paper aims to investigate the systematic risk exposure of Swedish hedge funds using a modified Fung & Hsieh (2004) asset-based style factor model. The results show that the average Swedish equity hedge fund and fund of funds had a significant positive exposure to the equity market portfolio and the spread between small cap and large cap stocks (SMB) during the sample period. This is consistent with our a priori expectations and previous international studies. We do not find the expected systematic fixed-income related risk exposure for the fixed-income hedge funds and fund of funds in the sample. The empirical material used in this study is taken from a publicly available fund database maintained by the Swedish Financial Supervisory Authority (Finansinspektionen).

The study's aim in a reflective way, highlighting key requirements for an accessible citizenship for the target audience, and thereby clarify the priorities in daily activities that can support an emancipatory citizenship process for people who have a cognitive delay..
Skillnader i uppvisat bias mellan utmanare och försvarare av status quo
De som förespråkar en ändring av det rådande läget (status quo), inom exempelvis politik, har visat sig vara mer påverkade av naiv realism än de som vill behålla status quo. Ytterligare studier visar att den politiska tillhörigheten kan vara av betydelse för hur påverkade av naiv realism dessa utmanare är. I två studier har det testats om naiv realism påverkas av positionen till status quo (utmana eller försvara) eller av den politiska tillhörigheten. I båda studier har en tydlig favorisering av den egna gruppen påträffats, samt att personer i utmanarposition gentemot status quo gjorde signifikant större skillnad mellan ingrupp och utgrupp än vad försvarare av status quo gjorde. Den politiska tillhörigheten visade sig inte vara av betydelse.

Ordklassers betydelse och effekter i enkätfrågor: Abstraktionsnivåer och Stereotyptänkande
Enkäter används flitigt idag. Spector (1994) menade att endast en liten del av den förklarade variansen i enkäter utgörs av det som önskas mäta. Bryggan mellan respondenten och enkäten är språket. Enligt Whorf-Safir hypotesen styrs våra tankar av språket. Semin och Fiedler (1988) menade att ordklasserna har olika abstraktionsnivåer.

En kognitiv semantisk analys av partikelverbet gå upp: : Conceptual Metaphor Theory (CMT) kontra Principled Polysemy Approach to Meaning Analysis (PPAMA)
This essay examines the differences and similarities, weaknesses and strengths of the two Cognitive Semantic theories Conceptual Metaphor Theory and Principled Polysemy Approach to Meaning Analysis. To illustrate the two theories, the Swedish verb-particle construction "gå upp" is examined and analyzed accordingly. The results showed differences in the number of polysemous meaning found. The methodological evaluation showed that the differences in the underlying ideas concerning meaning-construction behind these two theories make them incompatible..

Problematiska mönster eller enskilda problem? : En kvantitativ studie av kön och problembedömningar i socialtjänstens handläggning av ekonomiskt bistånd
I Sverige finns ett anmäkningsvärt stort utrymme för enskilda handläggares subjektivitet i bedömningen av socialbidragsklienter. Tidigare studier baserade på vinjettdata tyder på att handläggarnas bedömningar av klienternas problem och hja?lpbehov tenderar att reproducera traditionella ko?nsroller. Samtidigt saknas kunskap om betydelsen av kön i bedömningar av riktiga klienter. I den här studien analyseras könsrelaterade mönster i enkätdata om 138 handläggares bedömningar av psykosociala och hälsorelaterade problem hos 471 socialbidragsklienter.
Valet och kvalet kring kapitalstrukturen : om kognitionens inverkan på finansieringspolitiken
Background: A company?s choice of capital structure is influenced by the access to internal and external capital but also by the opportunities and threats that the management perceives in the environment and the management?s attitude towards risk. How an individual perceives and interpret the environment depends on the cognitive structures, which are shaped by personality, background and earlier experiences. Accordingly cognitive structures can be expected to influence the choice of capital structure. Purpose: Out of a cognitive perspective we intend to study the relationship between the way a company views it?s environment and what capital structure it chooses to have, in order to contribute to an increased understanding about what lies behind a company?s capital structure policy.
Hur förklarar företag i telekombranschen sina resultat i årsredovisningarna? : En studie över Phonera, Tele2 och TeliaSoneras resultatförklaringar 2001-2007
Previously studies have shown that the way companies explain outcome in their annual report is not totally trustworthy. Studies show that the management has a self serving bias when they explain the result to give a positive image of the company. Our study is based on investigations into this phenomenon in the telecom market in Sweden. Turbulent market conditions with, among other, deregulation of the monopoly of fixed telephony and a huge technical evolution, which has led to an increase in competition, is the reason to why we have chosen to study the telecom market in Sweden. As a benchmark in our study the attribution theory will be used.
