Psychological safety in high performance teams
Erfaringsbasert master, 90 st.p.Dette forskningsprosjektet har sitt utspring i et funn i forskningen til Amy Edmondson. I sin
bok The Fearless Organization beskriver hun at team som rapporterer feil, ogsÄ er de som
leverer det beste produktet. Gjennom arbeide med boken ble det raskt klart for oss at temaet
psykologisk trygghet og hvordan lederen kan pÄvirke dette var et omrÄde som var meget
spennende.
I denne masteroppgaven har vi fokusert pÄ hvordan man oppnÄr psykologisk trygghet i team,
og sĂŠrlig hvilken rolle lederen spiller i denne. Etter Ă„ ha arbeidet med temaet en periode, ble
derfor problemstillingen:
«Hvordan kan ledere lykkes med Ä etablere psykologisk trygghet i et
hÞyprestasjonsteam?»
Vi fikk tilgang til en relativ nyetablert avdeling ved Oslo Politidistrikt, Utrykningsenheten. Vi
gjennomfĂžrte intervjuer med et utvalg av teamledere og medarbeidere ved avdelingen.
Samtlige var Ă„pne, og delte av sine erfaringer og perspektiver. Gjennom disse samtalene fikk
vi en god innsikt i avdelingens indre, og hva de enkelte teamledere og medarbeidere tenkte og
gjorde som relateres opp mot psykologisk trygghet i deres gruppe.
Gjennom en enkel spÞrreundersÞkelse fikk vi fastslÄtt at teamene hadde gjennomgÄende hÞy
grad av psykologisk trygghet. I de semistrukturerte intervjuene fokuserte vi derfor pÄ hva de
konkret gjorde for Ă„ bygge psykologisk trygghet.
Ved bruk av kvalitativ metode opplever vi Ä ha fÄtt tak i de nyanser som framkom i
intervjuene, og denne mÄten Ä drive datainnsamling pÄ fungerte etter vÄr mening godt. Ved
bruk av refleksiv analysemetode fikk vi kategorisert og analysert dataene pÄ en oversiktlig
mÄte. Ved Ä gjÞre bruk av allerede tilgjengelig relevant litteratur har vi drÞftet de forskjellige
pÄstandene som kom fram i arbeidet med denne oppgaven.
Masteroppgavens hovedfunn er at lederne mÄ ta ansvar for relasjonene for Ä etablere
psykologisk trygghet i teamet, og mÄ lede gjennom gjensidig tillit. Lederne mÄ mestre
lederrollen, og teamet mÄ sammen skape en effektiv tilbakemeldingskultur gjennom aktive og
ansvarlige medarbeidere.Engelsk sammendrag (abstract):
This project has its origins in a discovery reported in the research of Amy Edmondson. In her
book âThe Fearless Organizationâ she describes how teams that feel able to report errors
are also those which deliver the best results. Working with her book, it quickly became clear
to us that the theme of psychological safety and how a leader can influence this, was an
extremely relevant and important area of study.
In this Masterâs thesis, we have focused on how one achieves safety within a team and,
especially, what role does the team leader play in this process. After thorough consideration
of our topic, we have chosen to focus on the following question:
âHow can a leader be successful in establishing psychological safety in a highperformance team?
We were allowed access to a relatively newly-established section within the Oslo Police
District, Rapid Response Unit, and we then carried out a series of interviews with both
team-leaders and their team- members. Through these interviews, we obtained very good
insight into the inner workings of the unit and how and what the team-leaders and individual
team âmembers thought and did in their work that relates to the establishment of feelings
of psychological safety within their group.
Using a simple questionnaire method, we found that we were able to detect nuances that
were revealed in the interviews and we concluded that this method of data- collection
worked well. By using a reflexive analysis method, we could categories and then
analyze the data in a coherent manner. By using already available literature, we have
discussed the relevant claims that have emerged from our work on this project.
Our Masterâs thesis main conclusion is that leaders must take responsibility for interpersonal
relations within their team in order to establish feelings of psychological safety, and lead
through reciprocal trust. Leaders must master their leadership role and the team must work
together to create an effective and responsible culture of reciprocal sharing of information
through active and responsible colleagues
Graphene for spintronics: giant Rashba splitting due to hybridization with Au
Graphene in spintronics has so far primarily meant spin current leads of high
performance because the intrinsic spin-orbit coupling of its pi-electrons is
very weak. If a large spin-orbit coupling could be created by a proximity
effect, the material could also form active elements of a spintronic device
such as the Das-Datta spin field-effect transistor, however, metal interfaces
often compromise the band dispersion of massless Dirac fermions. Our
measurements show that Au intercalation at the graphene-Ni interface creates a
giant spin-orbit splitting (~100 meV) in the graphene Dirac cone up to the
Fermi energy. Photoelectron spectroscopy reveals hybridization with Au-5d
states as the source for the giant spin-orbit splitting. An ab initio model of
the system shows a Rashba-split dispersion with the analytically predicted
gapless band topology around the Dirac point of graphene and indicates that a
sharp graphene-Au interface at equilibrium distance will account for only ~10
meV spin-orbit splitting. The ab initio calculations suggest an enhancement due
to Au atoms that get closer to the graphene and do not violate the sublattice
symmetry.Comment: 16 pages (3 figures) + supplementary information 16 pages (14
