Local Structure Studies of Ti for SrTi16O3 and SrTi18O3 by Advanced X-ray Absorption Spectroscopy Data Analysis

2015

Strontium titanate is a model quantum paraelectric in which in the region of dominating quantum statistics the ferroelectric instability is inhibited due to nearly complete compensation of the harmonic contribution into ferroelectric soft mode frequency by the zero-point motion contribution. The enhancement of atomic masses by the substitution of 18O for 16O decreases the zero-point atomic motion and low-T ferroelectricity in SrTi18O3 is realized. In this study we report on the local structure of Ti in SrTi16O3 and SrTi18O3 by Ti K-edge extended x-ray absorption fine structure measurements in temperature range 6 – 300 K.

“Equally, but in our own way” : First-time parents’ prenatal expectations of coparenting

2022

This study examined the expectations of expectant first-time parents on coparenting in a Finnish two-parent family. Thirty expectant couples were individually interviewed (N = 60) during the third trimester of pregnancy. The semi-structured interviews focused on participants’ expectations and hopes on future coparenting. Thematic analysis revealed that the expectant first-time mothers and fathers saw coparenting as multidimensional. They talked about coparenting in terms of 1) division of labour issues, 2) management of family dynamics, 3) childrearing agreement, 4) coparental support, and 5) learning and developing. Thus, the expectant couples hoped for a coparenting relationship in which …

Considerations regarding the Romanian fiscal and budgetary reform in accordance with the E.U. requirements

2006

The paper starts with the role of the Romanian fiscal and budgetary reform in the development and economical growth and has as purpose to emphasize the essential problems: the harmonization and fiscal coordination from the E.U. perspective; the Romanian fiscal and budgetary perspectives for period 2007-2009.

Transitions out of unemployment: The role of social networks' topology and firms' recruitment strategies

2011

In this paper we study the effects of job contact networks on out-of-unemployment transitions. We find that social connections produce sizable increases in upward mobility from unemployment and, caeteris paribus, symmetric network topologies perform better than asymmetric ones. Furthermore, in scale-free networks the probability of transitions out of unemployment increases in the exponent of the power-law degree distribution, but its value is much lower than the one attainable in Poisson random networks. In addition, and most interestingly, these results strongly depends on the different hypotheses on the firms' recruitment strategy.

Asymptotic theory of resonant tunneling in quantum waveguides of variable cross-section

2008

Halkaisijaltaan muunnellun kvanttiaaltojohtimen kapenemat toimivat tehokkaina potentiaalivalleina elektronin pitkittäissuuntaiselle liikkeelle. Kaksi kapenemaa muodostaa kvanttiresonaattorin, jossa resonoiva tunnelointi voi tapahtua. Tämä tarkoittaa sitä, että elektronit, joiden energia on lähellä resonanssia, läpäisevät resonaattorin todennäköisyydellä lähellä yhtä.Sarafanov kuvailee väitöskirjassaan asymptoottisesti elektroniaallon etenemistä kvanttiaaltojohtimessa, jossa on kaksi kapenemaa. Aaltoluvun k oletetaan olevan ensimmäisen ja toisen kynnysluvun välissä, jolloin vain sisään tuleva ja poismenevä aalto voivat edetä jokaisessa aaltojohtimen päässä äärettömyydessä. Väitöskirjassa esi…

Experimental and computational studies of transition metal complexes with polydentate amino- and amidophenolate ligands : synthesis, structure, react…

2013

Chelating polydentate ligands play a key role in several areas of modern coordination chemistry. They can be exploited, for example, in catalysis, bioinorganic chemistry, heavy metal abstraction and molecular magnetism. Furthermore, compounds of this type can be found in natural chemicals, commercial products and industrial applications. In this dissertation, several 3d, 4d and 5d transition metal complexes with polydentate amino- and amidophenolate ligands were prepared and their structure, reactivity and magnetic properties were studied with experimental and computational techniques. In the first part of the dissertation, the solid-state structure, reactivity and magnetic properties of 12…

Bold ambition, blunted agency? : Examining top management perspectives on a circular economy transition in Finland

2022

The circular economy is proposed as a company-driven means to further sustainability transitions. Top managers have a critical role in fostering the circular economy as they are responsible for shaping and implementing a company's sustainability strategy and performance. In this paper, we adopt a microfoundations perspective to enhance our understanding of the influence of top managers as agents of the sustainability transition to the circular economy. In a qualitative research study, we interviewed 34 top managers of Finnish companies that are actively pursuing the circular economy. The main implication of our study is in exploring the role of top managers, as they engage in actively struc…

Applying transdisciplinary sustainability transitions research in international social work doctoral training

2022

In the last 15 years, transdisciplinary research of sustainability transitions has become an increasingly powerful approach. We discuss it as a perspective for social work discipline, and as a theoretical-conceptual frame of a new international doctoral training and research programme in social work taking place in seven European countries. In our qualitative study, we investigate how the participating social work doctoral students reflect upon transdisciplinarity and understand the interconnectivity between environmental, ecological, and social sustainability transitions—which is widely recognised as a highly complex challenge of sustainability. The data used included the students’ learnin…

Reilu ruokamurros : Polkuja kestävään ja oikeudenmukaiseen ruokajärjestelmään

2022

Ruokajärjestelmämme kärsivät monista yhteen kietoutuneista kestävyysongelmista. Ongelmia ei korjata yksittäisillä teknologisilla ratkaisuilla, vaan muutoksia tarvitaan läpi koko ruokajärjestelmän. Muutosten laajuuden vuoksi on syytä puhua järjestelmän perustavanlaatuisesta muuttamisesta eli ruokamurroksesta. Tässä julkaisussa tarkastelemme, miten ruokajärjestelmän ilmastopäästöjä voitaisiin vähentää Suomessa siten, että ruokaturva ei vaarannu. Arvioimme ilmastotoimien toteutusta eri murrospoluilla, jotka keskittyvät maankäytön, ruokavalioiden, maatalous- ja ruokateknologioiden muutoksiin. Arvioimme eri murrospolkujen vaikutuksia maatalouteen eri alueilla ja eri väestöryhmien ravitsemukseen.…
