Emergent ultrafast phenomena in correlated oxides and heterostructures
2017
The possibility of investigating the dynamics of solids on timescales faster than the thermalization of the internal degrees of freedom has disclosed novel non-equilibrium phenomena that have no counterpart at equilibrium. Transition metal oxides (TMOs) provide an interesting playground in which the correlations among the charges in the metal $d$-orbitals give rise to a wealth of intriguing electronic and thermodynamic properties involving the spin, charge, lattice and orbital orders. Furthermore, the physical properties of TMOs can be engineered at the atomic level, thus providing the platform to investigate the transport phenomena on timescales of the order of the intrinsic decoherence ti…
Using Contextual Action Theory for conceptualization and research on adolescent development
2019
Recently, scholars’ calls for psychology to move beyond traditional ways of conceptualizing and researching human behaviour have increased. Contextual Action Theory (CAT) is a conceptual, methodological, and practical framework that is consistent with these calls. In CAT action is conceptualized as a complex, dynamic, and multidimensional system that can be comprehended from multiple levels of organization and from multiple perspectives. The Action-Project Method (A-PM) is the research method that emerged from CAT. It is a qualitative, naturalistic, process-oriented, longitudinal methodology that has been used to study joint, goal-directed actions and projects. The focus of data gathering a…
Il sé in gruppo e nell'ambiente ospitante. Un'analisi contestuale dell'esperienza di viaggio.
2012
With regard to a trip model articulated in contextual terms, the research proposes to trace the different expressive ways of some travellers in relationship to the places of which they had experience, with the purpose to emphasize the more stable personal learnings. The investigation moves from the administration of a semi-structured interview to 14 travellers, then analyzed through the IPA (Smith, Osborn 2003) and the CCRT (Luborsky, Crits-Christoph, 1990). The thematic picture sprung by the analysis has been prepared in topological terms, so that to furnish a comparison of reflections of consulted subjects compared to the groups of trip, to the entertaining environment and to themselves. …
Demographic inequalities as determinants and consequences of the COVID-19 pandemic in Latvia
2021
Since early March 2020 Latvia is fighting the COVID-19 pandemic. Lessons learned from this crisis will be instrumental in shaping future public health policy. Any policy response to the pandemic must be tailored to the particular risks within population in order to avoid the unnecessary social and economic damage on a national and international scale. Available literature on the topic highlights region-specific demographic factors associated with elevated population vulnerability to the effects of the COVID-19 pandemic. This study aims to ascertain the role of a pre-existing demographic inequalities in Latvia in the onset and progression of COVID-19 pandemic and lay groundwork for projectin…
A strong electroweak phase transition from the inflaton field
2016
We study a singlet scalar extension of the Standard Model. The singlet scalar is coupled non-minimally to gravity and assumed to drive inflation, and also couple sufficiently strongly with the SM Higgs field in order to provide for a strong first order electroweak phase transition. Requiring the model to describe inflation successfully, be compatible with the LHC data, and yield a strong first order electroweak phase transition, we identify the regions of the parameter space where the model is viable. We also include a singlet fermion with scalar coupling to the singlet scalar to probe the sensitivity of the constraints on additional degrees of freedom and their couplings in the singlet sec…
North/south differences among Italian emerging adults regarding criteria deemed important for adulthood and life satisfaction
2016
The main goal of this study was to compare Northern and Southern Italian emerging adult university students, regarding the importance attributed to criteria for adulthood and the levels of life and education satisfaction. Self-report questionnaires were filled by 475 Northern and Southern Italian University students (Age M = 22.91, 76% females, n = 359). Multivariate analysis of variance revealed that Southern emerging adults were more likely to place importance on family capacities, norm compliance, interdependence and role transitions as criteria for achieving adulthood than Northern emerging adults. Regarding gender differences, females were more likely to believe in the importance of no…
ISSP position stand : Transnationalism, mobility, and acculturation in and through sport
2017
The historically unprecedented pace of internationalising sport industry and transnational movement of athletic talent in the last 20 years has heightened the need for developing new competencies in research and daily practice of sport psychology professionals. While academic literature in cultural sport psychology and praxis has been increasing, sport professionals and local organisations seem to give scant time and resources to stay abreast of complex social changes in transnational industry and to the development of cultural competencies. Stemming from the continuing need for qualified athletic personnel to support transitioning athletes and to achieve intercultural effectiveness in dail…
Crystal structure and magnetic properties of (tris{4-[1-(2-methoxyethyl)imidazol-2-yl]-3-azabut-3-enyl}amine)iron(II) bis(hexafluoridophosph…
2019
The title compound, [Fe(C27H41N10O3)](PF6)2, is an example of an iron(II) spin-crossover compound. In this compound, C⋯F and CH⋯F/O contacts, present between the cations and anions, extend the structure into a three-dimensional supramolecular network.
High-Pressure Properties of Wolframite-Type ScNbO4
2022
In this work, we used Raman spectroscopic and optical absorption measurements and first-principles calculations to unravel the properties of wolframite-type ScNbO4 at ambient pressure and under high pressure. We found that monoclinic wolframite-type ScNbO4 is less compressible than most wolframites and that under high pressure it undergoes two phase transitions at ∼5 and ∼11 GPa, respectively. The first transition induces a 9% collapse of volume and a 1.5 eV decrease of the band gap energy, changing the direct band gap to an indirect one. According to calculations, pressure induces symmetry changes (P2/c–Pnna–P2/c). The structural sequence is validated by the agreement between phonon calcul…
Single crystal X-ray diffraction studies on [(CH3)nNH4–n]3[Sb2Cl9] (2,3) chloroantimonates(III) in their low-temperature ferroelectric phases—structu…
2005
The structures of two ferroic chloroantimonates(III): [(CH3)2NH2]3[Sb2Cl9] (DMACA) and [(CH3)3NH]3[Sb2Cl9] (TMACA) were determined in their low-temperature phases. The structure of DMACA was investigated at 100 and 15 K, and TMACA at 15 K. The structures consist of two-dimensional inorganic layers and organic cations bound together by the N(C)–H⋯Cl hydrogen bonds. All of the organic cations in both compounds at all studied temperatures are ordered. There is no indication of the structural phase transition in the structure of DMACA below 242 K. The geometry and distortions of the [SbCl6]3– octahedra in both compounds is discussed.
