Opin vísindi er varðveislusafn vísindaefnis og doktorsritgerða í opnum aðgangi á vegum íslenskra háskóla og Landsbókasafns Íslands - Háskólabókasafns.
Opinn aðgangur að rannsóknaniðurstöðum er í samræmi við 10. gr. laga nr. 3/2003 um opinberan stuðning við vísindarannsóknir sem og kröfur innlendra og erlendra rannsóknasjóða. Markmiðið með opnum aðgangi er að niðurstöður rannsókna séu aðgengilegar sem flestum óhindrað og án endurgjalds á rafrænu formi. Vistun í varðveislusafninu er varanleg og ætlað að tryggja aðgang að vísindaefni íslenskra háskóla í opnum aðgangi um ókomna tíð.

ANALYSING AND MODELLING RECORDED EARTHQUAKE INDUCED STRUCTURAL RESPONSE
(2004-08-01) Snæbjornsson, Jonas Thor; Carr, Athol J.; Sigbjornsson, Ragnar; Department of Engineering
Earthquake induced acceleration data has been systematically collected in two reinforced cast-in-place concrete buildings over periods of 14 and 5 years respectively and the database from the two buildings presently contains 870 records from 107 events ranging from magnitude 2 to 6 with acceleration amplitudes of up to 34 % g. This data is used to examine structural behaviour and system parameters and their dependence on excitation conditions. The system identification based on the sampled data serves both as a baseline for damage identification as well as calibration for further structural modelling of the buildings. Visible damage is slight, but the system parameters reflect structural changes. There are clear indications that the system parameters are amplitude dependent, even for relatively small response amplitudes. Inelastic dynamic analyses were also carried out on one of the structures to investigate the reliability of the analytical models and to estimate the capacity of the building to sustain future earthquake events. The results show that the model does represent the structure and although it came through the recent earthquakes with no damage the structure has limited capacity to withstand any event that would be larger than those experienced to date.
Application of lidars for assessment of wind conditions on a bridge site
(2015-06) Jakobsen, Jasna Bogunović; Cheynet, Etienne; Snæbjörnsson, Jónas Þór; Mikkelsen, Torben; Sjöholm, Mikael; Angelou, Nikolas; Mann, Jakob; Svardal, Benny; Kumer, Valerie; Reuder, Joachim; Department of Engineering
Wind measurement techniques based on remote optical sensing, extensively applied in wind energy, have been exploited in civil engineering only in a limited number of studies. The present paper introduces a novel application of wind lidars in bridge engineering, and presents the findings from the pilot measurement campaign on the Lysefjord Bridge in the South-West Norway. A single long-range pulsed WindScanner lidar and two short-range continuous-wave WindScanner lidars were deployed, in addition to five sonic anemometers installed on the bridge itself, the latter for long-term wind characterization. The paper presents a promising comparison of the measurements obtained by the three different sets of instruments, and discusses their complementary value.

Tactics in B2B Negotiations in SMEs
(Háskólinn í Reykjavík, 2018) Sigurðardóttir, Aldís Guðný; Candi, Marina; Department of Business and Economics
This thesis deals with negotiation tactics in business-to-business (B2B) settings. The term negotiation tactics refers to negotiator behavior, both verbal and non-verbal, throughout the negotiation process. The aim of this thesis is to examine the negotiation tactics used in actual, real-life B2B settings, and to explore what drives and influences negotiation behavior. The term negotiation tactics is well established in the negotiation literature, but the study of negotiation tactics has mainly focused on distinguishing among different types of tactics (e.g. ethical vs. non-ethical, aggressive vs. non-aggressive, competitive vs. cooperative). Actual, real-life use of negotiation tactics in B2B negotiations has been less studied. Because of the scarcity of research in this area, a research strategy combining qualitative and quantitative research methods was adopted for this project, which is built around three academic papers. Empirical data were collected from B2B small and medium-sized enterprises (SMEs) in four European countries: Iceland, Poland, Denmark, and Germany. The subject material is viewed through various theoretical lenses, including Social Identity Theory, Social Network Theory, B2B Marketing Theory, Expectancy Theory, Principal-Agent Theory, and Hofstede’s cultural dimensions. This thesis summarizes the papers’ main findings and resulting contributions to theory and practice. The findings of the first paper, which focuses on B2B negotiations in creative sectors and employs a case research methodology, indicate that negotiators in creative sectors use negotiation tactics whose underlying aim is to prioritize negotiators’ ability to create rather than securing economic gain. A category of negotiation tactics not anticipated by the existing literature—referred to as closure seeking tactics—was identified in the creative sector firms’ study. The findings of the second paper, which are based on observations of live, real-time negotiations, indicate that there are differences between buyers’ and sellers’ uses of negotiation tactics and that usage varies depending on a negotiator’s selected negotiation strategy. The findings further indicate that variable pay influences the negotiation behavior of both buyers and sellers and is associated with the use of competitive negotiation strategies, including distributive negotiation tactics, which could jeopardize firms’ long-term business relationships. Finally, the findings of the third paper, which reports on quantitative survey-based research, suggest that the use of integrative negotiation tactics is positively related to market performance and that this relationship is strengthened when combined with the use of distributive negotiation tactics. Based on a comparison between data collected in a risk-averse culture (Poland) and a risk-taking culture (Denmark), the findings indicate that in the risk-taking culture the use of integrative negotiation tactics is not related to market performance and the use of distributive negotiation tactics is negatively related to market performance. In the risk-averse culture, the use of both integrative and distributive tactics is positively related to market performance. Together, these findings suggest that in a culture where integrative negotiation tactics are expected, their use might not constitute a competitive advantage, which could explain the lack of a statistically significant relationship with market performance. Meanwhile, in a culture where distributive negotiation tactics might be the norm, the use of integrative tactics might constitute a competitive advantage. Overall, the findings of this research confirm the importance of better understanding negotiation tactics in B2B settings.
