Global-to-local incompatibility, monogamy of entanglement, and ground-state dimerization: Theory and observability of quantum frustration in systems …

2015

Frustration in quantum many body systems is quantified by the degree of incompatibility between the local and global orders associated, respectively, to the ground states of the local interaction terms and the global ground state of the total many-body Hamiltonian. This universal measure is bounded from below by the ground-state bipartite block entanglement. For many-body Hamiltonians that are sums of two-body interaction terms, a further inequality relates quantum frustration to the pairwise entanglement between the constituents of the local interaction terms. This additional bound is a consequence of the limits imposed by monogamy on entanglement shareability. We investigate the behavior …

Satisfied or Frustrated? A Qualitative Analysis of Need Satisfying and Need Frustrating Experiences of Engaging With Digital Health Technology in Chr…

2020

Introduction: Digital health technologies such as self-monitoring devices and apps are becoming increasingly important as tools to promote healthy habits and support individuals in their self-care. There is still a scarcity of research that builds on motivational theory to better understand the functioning of digital health technologies. The self-determination theory (SDT) is a macro theory of motivation that delineates three basic psychological needs that are linked to different types of motivation and lead to well-being when satisfied and illbeing when frustrated. Objective: To explore how the use of a digital tool for self-monitoring and communication with healthcare satisfies or frustra…

Violenza, frustrazione, vanità. La visione pessimistica di Leonardo da Vinci nel «Bestiario» e nelle «Favole»

2019

Nel «Bestiario» e nelle «Favole» di Leonardo da Vinci compare a più riprese una visione della realtà e dei rapporti fra gli individui (qui ovviamente simboleggiati dagli animali e dalle piante) caratterizzata da violenza e sopraffazione: aspetti, questi, che provocano sovente un senso di frustrazione (o di impotenza) in chi li subisce, onde si giunge, da parte dello scrittore, a una conclusione pessimistica, improntata alla considerazione della ineluttabile vanità delle cose. Violence, frustration, vanity. The pessimistic vision of Leonardo da Vinci in the «Bestiary» and in the «Fables» · Leonardo da Vinci’s «Bestiary» and «Fables» often show a vision of reality and relationships between in…

Leo Tolstoy’s and Joseph Conrad’s Relation to Music

2017

It is important to stress that Tolstoy’s and Conrad’s texts are to be understood to include not only literary, and thus verbal, texts but also elements of other media, such as music, theatre and visual arts. It should be noted that for Conrad music was also one of the arts that he greatly appreciated. Though Conrad’s main concern was to make us “see,” he was also concerned with making us “hear.” The use of music to accompany sexual desire, frustration and violence is a technique often used by the writer. Likewise, music had an enormous infl uence on Tolstoy. He was fascinated with its power, just as with the power of sexuality, beauty and war. His favourite composer was Chopin, but he also …

Measuring elderly people's quality of life through the Beck Hopelessness Scale: a study with a Spanish sample.

2016

Hopelessness is a key element of suicidal intent. It can instill a pessimistic outlook on the future, leading an individual to believe that suicide is the only answer to their problems. Hopelessness operates as a modulating variable between depression and suicidal behavior. The aim of this study was to confirm the factor structure of the Beck Hopelessness Scale (BHS) in a non-clinical sample.Three hundred and sixty-two Spanish individuals, aged over 60, free of cognitive impairment and depressive symptoms, completed the BHS scale. Participants were tested using confirmatory factor analysis (CFA), using one-, two- and three-factor models.The one- and two-factor models presented adequate fit …

Associations Between Peer Pressure and Adolescents' Binge Behaviors: The Role of Basic Needs and Coping

2019

Framed from a framework based on the integration of self-determination theory (Ryan & Deci, 2000 Ryan, R. M., & Deci, E. L. (2000). Self-determination theory and the facilitation of intrinsic motivation, social development, and well-being. American Psychologist, 55(1), 68–78. doi:10.1037/0003-066X.55.1.68 [Crossref], [PubMed], [Web of Science ®], , [Google Scholar] ) and Endler and Parker’s (1990) conception of coping strategies, the authors analyzed the relationships between peer pressure and binge behaviors (binge eating and binge drinking) in adolescence. Moreover, the authors explored the mediating role of satisfaction/frustration of basic psychological needs and coping strategi…

Phase Diagrams of Alloys and Adsorbed Monolayers: Some Recent Results

1997

We discuss some recent work done on the calculation of phase diagrams of models of binary alloys and adsorbed monolayers. For the nearest-neighbor Ising antiferromagnet on the fcc lattice (model for the Cu-Au system) we study a rather large lattice of 4 x 643 spins. This is necessary since the inherent frustration of the lattice induces a very small interfacial tension between ordered domains. We find no indications for the suggested L′ phase, and locate the triple point at a nonzero temperature. There is some numerical evidence that it might in fact be a multicritical point. We then discuss the extension of lattice gas models to “elastic lattice gases” (ELGs) which include also translation…

Guest induced reversible on–off switching of elastic frustration in a 3D spin crossover coordination polymer with room temperature hysteretic behavio…

2021

A binary reversible switch between low-temperature multi-step spin crossover (SCO), through the evolution of the population γHS(T) with high-spin (HS)-low-spin (LS) sequence: HS1LS0 (state 1) ↔ HS2/3LS1/3 (state 2) ↔ HS1/2LS1/2 (state 3) ↔ HS1/3LS2/3 (state 4) ↔ HS0LS1 (state 5), and complete one step hysteretic spin transition featuring 20 K wide thermal hysteresis centred at 290 K occurs in the three-dimensional (3D) Hofmann-type porous coordination polymer {FeII(3,8phen)[Au(CN)2]2}·xPhNO2 (3,8phen = 3,8-phenanthroline, PhNO2 = nitrobenzene), made up of two identical interpenetrated pcu-type frameworks. The included PhNO2 guest (x = 1, 1·PhNO2) acts as a molecular wedge between the interp…

Satisfaction and frustration of autonomy and relatedness needs: Associations with parenting dimensions and psychological functioning

2018

Framed from Basic Psychological Needs Theory (Ryan and Deci in American Psychologist 55:68–78; Ryan, Deci, American Psychologist 55:68–78, 2000) and Kagitcibasi’s Autonomous-Related Self Theory (Journal of Cross-Cultural Psychology 36:1–20; Kagitcibasi, Journal of Cross-Cultural Psychology 36:1–20, 2005), the study examined the relationships of adolescents’ satisfaction and frustration of autonomy and relatedness, with (a) adolescents’ perception of mother’s and father’s psychological control and autonomy support, and (b) adolescents’ self-acceptance and anxiety. Participants were 556 adolescents (M = 17.25, SD = 0.92). Path analysis showed more significant associations of autonomy support …
