Does time spent on device security and privacy inhibit online expression?
2019
Freedom of expression is a recognized human right. More recently, the UN has resolved that unrestricted access to the Internet is also a human right. A commonly accepted benefit of the Internet is that it serves as a platform for free expression. Usage of the Internet for free expression can be a way of circumventing censorship or other hindrances that prevent citizens' freedom of expression in more traditional publishing media. However, the Internet has unique security and privacy risks that may affect users' attitudes toward expressing themselves online. In the online environment, users with controversial viewpoints may be reluctant to express the viewpoints due to concern about possible …
B–T phase diagram of Pd/Fe/Ir(111) computed with parallel tempering Monte Carlo
2017
We use an atomistic spin model derived from density functional theory calculations for the ultra-thin film Pd/Fe/Ir(111) to show that temperature induces coexisting non-zero skyrmion and antiskyrmion densities. We apply the parallel tempering Monte Carlo method in order to reliably compute thermodynamical quantities and the B-T phase diagram in the presence of frustrated exchange interactions. We evaluate the critical temperatures using the topological susceptibility. We show that the critical temperatures depend on the magnetic field in contrast to previous work. In total, we identify five phases: spin spiral, skyrmion lattice, ferromagnetic phase, intermediate region with finite topologic…
Characterizing and Quantifying Frustration in Quantum Many-Body Systems
2011
We present a general scheme for the study of frustration in quantum systems. We introduce a universal measure of frustration for arbitrary quantum systems and we relate it to a class of entanglement monotones via an exact inequality. If all the (pure) ground states of a given Hamiltonian saturate the inequality, then the system is said to be inequality saturating. We introduce sufficient conditions for a quantum spin system to be inequality saturating and confirm them with extensive numerical tests. These conditions provide a generalization to the quantum domain of the Toulouse criteria for classical frustration-free systems. The models satisfying these conditions can be reasonably identifi…
The role of teachers’ controlling behaviour in physical education on adolescents’ health-related quality of life : test of a conditional process model
2019
Students’ health-related quality of life (HRQoL) may depend on the extent to which the school environment fostered by their teacher is perceived as autonomy-supportive. We tested a conditional process model in a physical education context in which students’ perception of their teachers’ autonomy-supportive behaviour moderated the relationship between perceived controlling behaviour and HRQoL via need frustration. School students (N = 1042) completed self-report measures of perceived teachers’ autonomy support, perceived controlling behaviour, need frustration, and HRQoL. As predicted, the effect of perceived teachers’ controlling behaviour on HRQoL was mediated by need frustration. Perceive…
Appraisal and Mental Contents in Human-Technology Interaction
2015
User experience has become a key concept in investigating human-technology interaction. Therefore it has become essential to consider how user experience can be explicated using psychological concepts. Emotion has been widely considered to be an important dimension of user experience, and one obvious link between modern psychology and the analysis of user experience assumes the analysis of emotion in interaction processes. In this paper, the focus is on the relationship between action types and elicited emotional patterns. In three experiments including N = 40 participants each, it is demonstrated that the types of emotions experienced when people evaluate and use technical artefacts differ…
Rhombi-chain Bose-Hubbard model: Geometric frustration and interactions
2018
We explore the effects of geometric frustration within a one-dimensional Bose-Hubbard model using a chain of rhombi subject to a magnetic flux. The competition of tunnelling, self-interaction and magnetic flux gives rise to the emergence of a pair-superfluid (pair-Luttinger liquid) phase besides the more conventional Mott-insulator and superfluid (Luttinger liquid) phases. We compute the complete phase diagram of the model by identifying characteristic properties of the pair-Luttinger liquid phase such as pair correlation functions and structure factors and find that the pair-Luttinger liquid phase is very sensitive to changes away from perfect frustration (half-flux). We provide some propo…

Emotional obstacles for e-learning – a user psychological analysis
2010
E-oppimisen merkitys koulutuksessa on kasvanut jatkuvasti. Sekä julkisen että yksityisen sektorin organisaatiot käyttävät sitä laajasti. Epäilyjä kuitenkin on ilmaistu sen tehokkuuden osalta. Nämä ongelmat johtuvat usein ihmisen ja järjestelmän vuorovaikutuksesta, minkä vuoksi on tarpeen tutkia vuorovaikutusta e-oppimisessa. Me lähestymme näitä vuorovaikutusongelmia käyttäjäpsykologisesta näkökulmasta. Tämä tarkoittaa sitä, että käytämme psykologisia käsitteitä, menetelmiä ja teorioita ratkaistaksemme vuorovaikutusongelmia. Tässä artikkelissa haluamme korostaa, että on olemassa monia tunneperäisiä näkökulmia ihmisen ja teknologian vuorovaikutuksen prosesseille, ja siksi me analysoimme e-opp…
Prejudice and need for relatedness expressed in the narratives of Finnish Roma early school leavers: A multi-case study
2023
AbstractSchool discontinuation in Finland is more common among the Finnish Roma than among the population as a whole. We lack knowledge of the perspective of those of the Roma, representing a minority inside a minority, who have left compulsory school without a leaving certificate. Within a study about school experiences of imprisoned early school leavers in Finland we had six participants with a Finnish Roma background, whose experiences of relatedness, and frustration of it, we examine in this paper. We conducted narrative interviews with the participants, applying a co-operative narrative interpretation to the meanings of what was told. After the field process, we interpreted the narrati…
Revisiting the Narratives of Finnish Early School Leavers: Mapping Experiences of Detachment through a Self-determination Theory Lens
2022
Basic psychological needs and people’s experiences affect the choices they make, and further shape the trajectories followed through school. The present study focuses on the perspectives of people who left school without graduating. Through narrative interviewing processes we collected the storied experiences of eleven imprisoned early school leavers in Finland. We triangulated data-driven themes and used as theory the concept of three basic psychological needs: autonomy, competence, and relatedness. Of these, relatedness was the most common and a shared topic brought forth by the participants. Experiencing dissatisfaction and frustration as a result of the need for relatedness played a cru…
