Do metric fluctuations affect the Higgs dynamics during inflation?
2017
We show that the dynamics of the Higgs field during inflation is not affected by metric fluctuations if the Higgs is an energetically subdominant light spectator. For Standard Model parameters we find that couplings between Higgs and metric fluctuations are suppressed by $\mathcal{O}(10^{-7})$. They are negligible compared to both pure Higgs terms in the effective potential and the unavoidable non-minimal Higgs coupling to background scalar curvature. The question of the electroweak vacuum instability during high energy scale inflation can therefore be studied consistently using the Jordan frame action in a Friedmann--Lema\^itre--Robertson--Walker metric, where the Higgs-curvature coupling …
Despicable dark relics: generated by gravity with unconstrained masses
2019
We demonstrate the existence of a generic, efficient and purely gravitational channel producing a significant abundance of dark relics during reheating after the end of inflation. The mechanism is present for any inert scalar with the non-minimal curvature coupling $\xi R\chi^2$ and the relic production is efficient for natural values $\xi = {\cal O}(1)$. The observed dark matter abundance can be reached for a broad range of relic masses extending from $m \sim 1 {\rm k eV}$ to $m \sim 10^{8} {\rm GeV}$, depending on the scale of inflation and the dark sector couplings. Frustratingly, such relics escape direct, indirect and collider searches since no non-gravitational couplings to visible ma…
The body-mind problem from a personality relativity theory approach: (Relativity of personality)
2012
The body-mind problem is here posed fromthe General Factor of Personality Theory and mathematically presented as a relativity theory: 1. A two-level-invariant model; 2. The transformation equation between both levels. On a hand, the investigation of personality dynamicsas a consequenceof a stimulant drug provides a system of two coupled differential equations, which adapts to both biological (body) and psychological (mind)levels ofdescription. On the other hand, a system of two coupled partial differential equations is here deduced as the transformation model between the biological and psychological levels. Both models are presented and validated in this paper. The experimental design to va…
Universality of the Triangular Theory of Love: Adaptation and Psychometric Properties of the Triangular Love Scale in 25 Countries
2021
The Triangular Theory of Love (measured with Sternberg’s Triangular Love Scale – STLS) is a prominent theoretical concept in empirical research on love. To expand the culturally homogeneous body of previous psychometric research regarding the STLS, we conducted a large-scale cross-cultural study with the use of this scale. In total, we examined more than 11,000 respondents, but as a result of applied exclusion criteria, the final analyses were based on a sample of 7332 participants from 25 countries (from all inhabited continents). We tested configural invariance, metric invariance, and scalar invariance, all of which confirmed the cultural universality of the theoretical construct of love …
Teacher, peer and parent autonomy support in physical education and leisure-time physical activity: A trans-contextual model of motivation in four na…
2009
An extended trans-contextual model of motivation for health-related physical activity was tested in samples from four nations. The model proposes a motivational sequence in which perceived autonomy support from teachers in a physical education (PE) context and from peers and parents in a leisure-time physical activity context predict autonomous motivation, intentions and physical activity behaviour in a leisure-time context. A three-wave prospective correlational design was employed. High-school pupils from Britain, Estonia, Finland and Hungary completed measures of perceived autonomy support from PE teachers, autonomous motivation in both contexts, perceived autonomy support from peers and…
Farmers' participation in civic agriculture: The effect of social embeddedness
2014
This work investigates how farmers??? attitudes influence their decision to participate in some particular forms of civic agriculture, namely farmers' markets (conventional or organic), solidarity purchase groups, direct selling and box schemes. It also explores whether social embeddedness-related attitudes occur with different intensities within the various types of civic agriculture. To this end, a survey was carried out among farmers participating in civic agriculture in Sicily (Italy). Empirical results confirm the role of social embeddedness whereby personal relations between farmers and consumers are emphasised: a greater presence of community relations fosters a greater role of socia…
Commenting on Historical Writings in Medieval Latin Europe : A Reconnaissance
2015
Modern scholarship seems to undervalue medieval commentaries on historical writings. This article intends to bring this phenomenon to scholars’ attention by providing a preliminary overview of the forms and subjects of such commentaries. It examines various types of evidence including not only a few commentaries proper (Nicolas Trevet’s on Livy and John of Dąbrówka’s on Vincent of Cracow), but also different apparatus consisting of more or less systematic interlinear and marginal glosses and commentary-like additions to vernacular translations, mostly of Italian and French origin. It begins by considering various consultation-related signs and annotations, such as cross-references. Then, it…
The Influence of the Avicennan Theory of Science on Philosophical Sufism
2020
Abstract This article discusses the application of the Avicennan theory of demonstrative science on taṣawwuf, or the Divine Science (al-ʿilm al-ilāhī), by members of the Akbarian tradition, particularly Ibn ʿArabī’s (d. 1240) stepson and most influential disciple, Ṣadr al-Dīn al-Qūnawī (d. 1274), and his commentators, among whom the most prominent was Mullā Muḥammad b. Ḥamza al-Fanārī (d. 1431). It aims to find out what kind of relationship was developed between Avicennan logic and Sufism by the two members of the Akbarian school in the post-classical Islamic thought. It also seeks to show that the convergence between different currents of Islamic thought—Sufism and philosophy in this case—…
Moral panic, moral regulation and essentialization of identities: Discursive struggle over unethical business practices in the Finnish national media
2013
The study sheds light on the language of moral panic and moral regulation in the Finnish news media over a 9-year period on the subject of cartels and cartel agreements. What makes the case particularly interesting is that the object of the most explicit moral panic was the introduction of new laws (leniency programmes) designed to regulate illegal cartel behaviour. The main argument is that the construction of both moral regulation and moral panic in news media takes place through essentializing discursive claims that contribute to national identity construction. The study contributes to current literature on moral panics as ideologico-discursive phenomena and throws some light on the powe…
From subatomic to immense: About the possible influence of the Theory of Relativity and Quantum Mechanics in the fantastic
2015
The fantastic is based on three pillars: reality, the impossible and fear. Theoretical physics is a branch of science that has deeply studied reality, from the subatomic world to the immensity of outer space. In this article, we want to study how the Theory of Relativity and the Quantum Mechanics have influenced the configuration of the fantastic, and in addition, we want to verify if these branches of physics are capable of explaining certain fantastic phenomena.
