Factor analysis is a well-known statistical method to describe the variability of observed variables in terms of a smaller number of unobserved latent variables called factors. Even though latent factors are conceptually independent of each other, their influence on the observed variables is often joint and synergistic. We propose to quantify the synergy of the joint influence of factors on the observed variables using O-information, a recently introduced metric to assess high-order dependencies in complex systems; in the proposed framework, latent factors and observed variables are jointly analyzed in terms of their joint informational character. Two case studies are reported: analyzing resting fMRI data, we find that DMN and FP networks show the highest synergy, consistent with their crucial role in higher cognitive functions; concerning HeLa cells, we find that the most synergistic gene is STK-12 (AURKB), suggesting that this gene is involved in controlling the HeLa cell cycle. We believe that our approach, representing a bridge between factor analysis and the field of high-order interactions, will find wide application across several domains. Full article

The relationship between income and subjective well-being (SWB) has been widely studied. While previous research has shown that the correlation between income and SWB is not always strong, there is limited research examining how the choice of SWB index influences this relationship. Drawing on survey data collected from 32 countries between 2015 and 2017, this study explores how the income–SWB relationship varies across different SWB indices. The dataset encompasses both developed and developing nations. We analyzed six types of SWB indices documented in the literature—covering a broader range than is typically included—and conducted comparative analyses. To account for the possibility of a nonlinear relationship between income and these SWB measures, we used a semiparametric approach by applying generalized additive models. Our findings show that these six indices can be categorized into three groups: (1) mental health and affect balance, (2) subjective happiness and eudaimonia, and (3) life satisfaction and the Cantril Ladder. These results underscore the significant impact that the selected SWB index can have on the income–SWB relationship. While economic development is often assumed to enhance SWB, our analysis reveals that this relationship does not hold consistently across all SWB indicators. In particular, certain indicators show little or no improvement in well-being despite increasing income levels, suggesting the presence of excessive or inefficient consumption that fails to contribute to genuine human flourishing. These findings challenge the conventional growth-centric paradigm and call for a deeper societal and academic inquiry into what constitutes “true prosperity.” From a sustainability perspective, aligning economic progress with authentic improvements in well-being is essential. This requires not only more careful selection and interpretation of SWB metrics, but also a broader re-evaluation of consumption patterns and policy goals to ensure that future development contributes meaningfully to human and ecological well-being.

Unlike many philosophers in the last quarter of the 20th century, many current scholars of Aristotle are less critical of the doctrine of the reciprocity of the virtues. They recognize that the reciprocity of the virtues is grounded in Aristotle’s accounts of eudaimonia, moral virtue, and phronēsis. However, there remains a concern that if the phronimos must have all the moral virtues in addition to phronēsis, then the phronimos is, for actual humans, unattainable. In what follows, I will argue that Aristotle’s phronimos is intended to be attainable and attributable to actual humans. In Part 2 of the paper, I will set out some preliminary points about the “methodology” Aristotle employs in his ethics, with special attention to the need to reconcile as many of the phenomena as one can and the recognition of the inescapable imprecision of ethics. In Part 3 of the paper, I will discuss passages where Aristotle insists upon the attainability of both eudaimonia and the moral virtues. In Part 4, I will explore how moral virtue and phronēsis admit of degrees and that his distinction between heroic virtue and moral virtue supports the attainability and attributability of the latter. Finally, in Part 5, I will propose a plausible reading of the reciprocity of the virtues that supports the thesis that the phronimos is attainable. Full article

In the Kolmogorov Theory of Consciousness, algorithmic agents utilize inferred compressive models to track coarse-grained data produced by simplified world models, capturing regularities that structure subjective experience and guide action planning. Here, we study the dynamical aspects of this framework by examining how the requirement of tracking natural data drives the structural and dynamical properties of the agent. We first formalize the notion of a generative model using the language of symmetry from group theory, specifically employing Lie pseudogroups to describe the continuous transformations that characterize invariance in natural data. Then, adopting a generic neural network as a proxy for the agent dynamical system and drawing parallels to Noether’s theorem in physics, we demonstrate that data tracking forces the agent to mirror the symmetry properties of the generative world model. This dual constraint on the agent’s constitutive parameters and dynamical repertoire enforces a hierarchical organization consistent with the manifold hypothesis in the neural network. Our findings bridge perspectives from algorithmic information theory (Kolmogorov complexity, compressive modeling), symmetry (group theory), and dynamics (conservation laws, reduced manifolds), offering insights into the neural correlates of agenthood and structured experience in natural systems, as well as the design of artificial intelligence and computational models of the brain.

The current study seeks to explore the underexamined or potentially under-researched social dimensions of circular economy (CE) in the context of buildings. Utilising a meta-synthesis approach, this paper builds on the two primary theoretical frameworks in the well-being literature: the eudaimonic and hedonic perspectives. The analysis of the selected articles reveals that these frameworks foster distinct modes of interaction and perception concerning one’s environment. A consensus is evident among the studies reviewed, advocating for integrating both eudaimonic and hedonic elements to achieve optimal well-being and happiness. Moreover, some scholars argue that for the attainment of sustainability goals and, by extension, CE objectives, the eudaimonic approach to well-being should be emphasised over the currently predominant hedonic inclinations. The research also attempts to open a discourse between the sometimes rather comprehensive, holistic, and hard-to-quantify dimensions of human well-being and the more logical, measurable, and tangible results-oriented approach towards the built environment. This investigation illustrates how well-designed building elements, aligned with CE principles, can play a pivotal role in fostering both environmental sustainability and human flourishing in the built environment.

Entropy management, central to the Free Energy Principle, requires a process that temporarily shifts brain activity toward states of lower or higher entropy. Metastable synchronization is a process by which a system achieves entropy fluctuations by intermittently transitioning between states of collective order and disorder. Previous work has shown that collective oscillations, similar to those recorded from the brain, emerge spontaneously from weakly stable synchronization in critically coupled oscillator systems. However, direct evidence linking the formation of collective oscillations to entropy fluctuations is lacking. In this short communication, we demonstrate how the emergence of Metastable Oscillatory Modes (MOMs) is directly associated with a temporary reduction in entropy in the ongoing dynamics. We apply Shannon entropy to the distribution of eigenvalues of phase covariance over sliding time windows, capturing the temporal evolution of entropy at the level of the entire dynamical system. By demonstrating how the formation of MOMs impacts a system’s entropy levels, we bridge theoretical works on the physics of coupled oscillators with the FEP framework, supporting the hypothesis that brain rhythms recorded experimentally are a signature of entropy management.

Major Depressive Disorder (MDD) is a complex, heterogeneous condition affecting millions worldwide. Computational neuropsychiatry offers potential breakthroughs through the mechanistic modeling of this disorder. Using the Kolmogorov theory (KT) of consciousness, we developed a foundational model where algorithmic agents interact with the world to maximize an Objective Function evaluating affective valence. Depression, defined in this context by a state of persistently low valence, may arise from various factors—including inaccurate world models (cognitive biases), a dysfunctional Objective Function (anhedonia, anxiety), deficient planning (executive deficits), or unfavorable environments. Integrating algorithmic, dynamical systems, and neurobiological concepts, we map the agent model to brain circuits and functional networks, framing potential etiological routes and linking with depression biotypes. Finally, we explore how brain stimulation, psychotherapy, and plasticity-enhancing compounds such as psychedelics can synergistically repair neural circuits and optimize therapies using personalized computational models.

Considering that research points to the discrepancy regarding the positive role of hedonia as opposed to eudaimonia in physical health, the aim of this study was to investigate the moderating effects of hedonia and eudaimonia on the relationship between stress and general mental health in young adults. A total of 328 participants took part in the study, 36.6% of whom were males, with ages ranging from 18 to 30, and a median age of 19 years (SD = 1.32). Questionnaires were used to measure well-being states, stress, and mental health. The results showed that hedonia moderated the relationship between low-stress conditions and general mental health. Eudaimonia, on the other hand, had a nonsignificant effect on the relationships tested. The findings indicate that an orientation toward pleasure may be the path to achieving mental health in the midst of stressful circumstances. Full article

This study investigates the mechanisms of virtual reality (VR) tourism’s impact on the well-being of residents in long-term care facilities (LTCFs). It aims to understand how presence and flow during VR experiences can enhance well-being. This experimental study used a quantitative approach with structured questionnaires to investigate VR experiences among LTCF residents in Taiwan. After obtaining ethical approval, 145 eligible participants from four LTCFs completed a full five-week VR tourism experience. Data collection took place from June to November 2022. This study employed Partial Least Squares Structural Equation Modeling (PLS-SEM) with Smart PLS software to analyze the causal relationships between latent variables. The results confirm that the more vivid the virtual reality image (β = 0.240, p < 0.05), the more immersive the experience (β = 0.267, p < 0.05), the greater the ability to control the experience (β = 0.465, p < 0.001), and the greater the ability to stimulate curiosity during the experience (β = 0.290, p < 0.05), the greater the sense of presence. Increased presence leads to user engagement and a state of flow (β = 0.556, p < 0.001), which is essential for personal hedonia (β = 0.453, p < 0.001) and eudaimonia (β = 0.220, p < 0.001). This study elucidates the mechanisms through which VR tourism experiences enhance well-being among LTCF residents, emphasizing the critical roles of presence and flow in promoting both hedonic and eudaimonic dimensions of well-being.

We evolved our past Portfolio Yield Reactive (PYR) model to provide a competitive system with infiltration of categorical information and fundamentals into advanced higher-order moments that support more objective portfolio selection aided by intelligent computing. The system of the PYR model searches for hidden corporate performance prototypes in big data from accounting and financial statements. The PYR model restricts malicious patterns, such as hoaxes, noise, and manipulation, incorporated into a novel optimal portfolio selection method. Full article

Cultivating an eudaimonic lifestyle benefits mental health. However, it is not known under which circumstances the benefits of eudaimonia are the most pronounced. This cross-sectional study aimed to examine psychological needs (autonomy, competence, and relatedness) as the moderators of the effects eudaimonia has on mental health (general mental health, positive and negative mental health). In total, 328 young adults took part in this study, of which 36.6% were males, whose ages ranged between 18 and 30, with a median of 19 years (SD = 1.32). Questionnaires were used to measure eudaimonia (The Eudaimonia Scale from The Hedonic and Eudaimonic Motives for Activities), psychological needs (The Basic Psychological Needs Scale), and mental health (The Mental Health Inventory). To analyze the data, hierarchical regression analyses and analyses of variance have been performed. The results revealed that of all psychological needs, only the need for relatedness moderated the relationship between eudaimonia and general mental health and eudaimonia and negative mental health. Individuals with high eudaimonia and a highly satisfied need for relatedness had good general mental health and fewer mental health disturbances. The findings suggest that if one practices meaningful behaviors, the positive change in the mental health domain is greatest when those actions benefit not only this individual but others as well.

Smell loss affects around 15–20% of the population, with a major effect on the quality of life. The most common complaint is the impairment of the eating experience, with around 90% of patients reporting this issue. A study conducted at a specialised Taste and Smell Clinic investigated if food and cooking can positively affect the enjoyment of food, subjective cooking skills, and quality of life in patients with smell loss. The 49 participants in the study received a 5-week cooking school course that focused on emphasizing the other senses to regain the enjoyment of food. Participants gained more confidence in cooking, and their quality of life improved significantly. Positively evaluated recipes were adjusted based on feedback and published as free e-books in Danish, German, and English. Eating and cooking are multisensory experiences, and the perception of food depends on the complex interaction of senses and surroundings. If the olfactory input is reduced or absent, both the enjoyment and cooking experience can be negatively affected. Therefore, focusing on food and cooking can have a positive impact on patients with smell loss. Full article

We explore the intersection of neural dynamics and the effects of psychedelics in light of distinct timescales in a framework integrating concepts from dynamics, complexity, and plasticity. We call this framework neural geometrodynamics for its parallels with general relativity’s description of the interplay of spacetime and matter. The geometry of trajectories within the dynamical landscape of “fast time” dynamics are shaped by the structure of a differential equation and its connectivity parameters, which themselves evolve over “slow time” driven by state-dependent and state-independent plasticity mechanisms. Finally, the adjustment of plasticity processes (metaplasticity) takes place in an “ultraslow” time scale. Psychedelics flatten the neural landscape, leading to heightened entropy and complexity of neural dynamics, as observed in neuroimaging and modeling studies linking increases in complexity with a disruption of functional integration. We highlight the relationship between criticality, the complexity of fast neural dynamics, and synaptic plasticity. Pathological, rigid, or “canalized” neural dynamics result in an ultrastable confined repertoire, allowing slower plastic changes to consolidate them further. However, under the influence of psychedelics, the destabilizing emergence of complex dynamics leads to a more fluid and adaptable neural state in a process that is amplified by the plasticity-enhancing effects of psychedelics. This shift manifests as an acute systemic increase of disorder and a possibly longer-lasting increase in complexity affecting both short-term dynamics and long-term plastic processes. Our framework offers a holistic perspective on the acute effects of these substances and their potential long-term impacts on neural structure and function. Full article

Background and aim: The dimension of purpose in life (PiL) is one of the core features of eudaimonia and plays a crucial role in developmental settings. However, few studies have examined purpose in life in younger generations and verified if it is amenable to improvements following a wellbeing-promoting intervention. The aim of the present investigation is to explore correlates and predictors of purpose in life in school children and to test if it can be ameliorated after school-based wellbeing interventions. Methods: A total of 614 students were recruited in various schools in Northern Italy. Of these, 456 belonged to junior high and high schools and were randomly assigned to receive a protocol of School Well-Being Therapy (WBT) or a psychoeducational intervention (controls). A total of 158 students were enrolled in elementary schools and received a positive narrative intervention based on fairytales or were randomly assigned to controlled conditions. All students were assessed pre- and post- intervention with Ryff scales of eudaimonic wellbeing (short version) and with other self-report measures of anxiety, depression and somatization. Additionally, the Strengths and Difficulties Questionnaire (SDQ) was administered to their schoolteachers as observed–rated evaluation. Results: In both elementary and high schools, purpose in life after the intervention was predicted by initial depressive symptoms and by group assignment (positive interventions vs. controls). In older students, PiL was predicted by female gender and anxiety levels, while no specific strengths identified by teachers were associated with PiL. Conclusions: PiL plays an important and strategic role in developmental settings, where students can develop skills and capacities to set meaningful goals in life. Depressive symptoms and anxiety can be obstacles to developing PiL in students, while positive school-based interventions can promote this core dimension of eudaimonia. Full article
