We study a regularized version of Van Hove’s 1952 model, in which a quantum field interacts linearly with sources of finite width lying at fixed positions. We show that the central result of Van Hove’s 1952 paper on the foundations of Quantum Field Theory, the orthogonality between the spaces of state vectors which correspond to different values of the parameters of the theory, disappears when a well-defined model is considered. We comment on the implications of our results for the contemporary (...) relevance of Van Hove’s article. (shrink)

Complex crises like the coronavirus pandemic are showing us that modern societies are becoming increasingly unable to live in equilibrium with nature. These crises are the result of multiple causes, which interact at different scales and across different domains. Therefore, investigating their proximate causes is not enough to fully understand them. It is also crucial to take into account the structural factors involved. As concerns the global pandemic, I suggest four levels of analysis: (i) the surface or “proximate” level of (...) the crisis; (ii) the human–environment–animal interface, as pointed out by the One Health approach; (iii) the broader socioeconomic context; and (iv) the deeper or worldview level. Furthermore, I argue that there is the need for a mindset shift if we want to properly trace causality. Much more attention must be given to the study of multilevel connecting patterns and nonlinear mechanisms as the producers of emergent global effects. (shrink)

The potential for jointly using or integrating Western science and indigenous knowledge, especially in such fields as environmental management, is a hotly debated topic nowadays. However, the difficulties involved in such a task are not always fully understood and co-management experiences achieved only partially the expected outcomes. In this contribution, I show how a sound combination of the two bodies of knowledge would be possible only if there is a way to accommodate different interpretations of reality and knowledge criteria. The (...) issue should then be faced at the epistemological level too, discussing the possibility and implications of a genuine epistemic pluralism. With reference, among others, to Feyerabend’s later writings, here I illustrate some possible insights for addressing the matter that a Western perspectivist stance could provide. (shrink)

During the COVID-19 pandemic, scientific experts advised governments for measures to be promptly taken; they also helped people to understand the situation. They carried out this role in the face of a worldwide emergency, when scientific understanding was still underway. Public scientific disputes also arose, creating confusion among people. This article highlights the importance of experts’ epistemic stance under these circumstances. It suggests they should embrace the intellectual virtue of epistemic humility, regulating their epistemic behavior and communication accordingly. In so (...) doing, they would also favour the functioning of the broad network of knowledge-based experts, which is required to properly address all the aspects of the global pandemic. (shrink)

Descartes's distinction between res cogitans and res extensa is a paradigmatic concept on which Western thought has been grounded. The reductionist and objectivistic approach of modern science draws its fundamental premise from it. This dualism has also instigated a view of human as separate from nature. The complexity approach in its most radical form questions many of these assumptions, asserting that the subjective and objective dimensions are involved in a relation of mutual determination and dependence. This article argues that if (...) the dualistic metaphysics is replaced by a vision emphasizing this mutual dependence, a new way of interacting with nature may also be fostered. (shrink)

The radical changes deriving from the COVID-19 emergency have heavily upset some of the most familiar routines of daily work life. Abruptly, many workers have been forced to face the difficulties that come with switching to remote working. Basing on the theoretical framework proposed by the Job Demands-Resources model, the purpose of this paper was to explore the effect of work overload, on behavioral stress, meant as an outcome linked to the health impairment process. Furthermore, the aim of the study (...) was to explore the mediating role of job crafting, considered as a second-order construct consisting of two dimensions in the abovementioned relation. Participants were 530 workers experiencing remote working or work-from-home during the first COVID-19 lockdown in Italy. Hypotheses were explored by using three different latent variables, measured reflexively through indicators on a 5-point scale, extracted from validated questionnaires. Data analysis was performed through Structural Equation Modeling; to test the mediation, bootstrap validation was computed. Results showed that the mediation of job crafting was partial. More specifically, the direct effect between work overload and behavioral stress was positive; moreover, the indirect, negative effect through the mediation of job crafting was also significant. Therefore, results showed that job crafting can play a crucial role as a protective factor supporting the activation and adjustment of suitable resources; these resources can be useful to deal with the negative effects of work overload, particularly under the condition of heavy remote working and use of technologies, on individual outcomes. Starting from the current global scenario of the pandemic that has not yet ceased its effects, the study suggested decisive theoretical and practical implications. Accordingly, findings extended the current trends in occupational health psychology research, with special reference to the mainstream topic “work and COVID-19” in the Italian context. Finally, results can give suggestions to companies engaged in managing change, recommending that they build a collaborative workplace at the individual and collective level to implement job crafting interventions and enrich the personal and organizational resources of workers, which is useful cope with the current demands.

First, the article illustrates the concept of ‘cultural heritage’ as traditionally meant, namely relying on a historically consolidated narrative. Next, it undertakes a broader conceptual analysis and deals with three distinct issues: (i) the fact that the conceptualizations and uses of heritage largely depend on long lasting dichotomies (e.g., tangible/intangible, natural/cultural); (ii) the way in which cultural backgrounds shape the dynamics of valuing and approaching heritage; (iii) the temporal framing of heritage, which today, in the Anthropocene, also points towards how (...) to deal with a future of uncertainty. Lastly, it introduces the notion of epistemic heritage, (i.e., the existence of multiple cultural ways of knowing), investigating its implications for both how cultural heritage is conceived and the future approached.

The author, starting from what is currently known about cup-marks and their distribution in the north-western Italian alpine area, formulated a hypothesis on their material and ritual functions in the Neolithic period. It is conceivable that cup-marks were originally carved in connection with the ritual use of Amanita muscaria, and that they may later have assumed other functions as well.

This textbook covers all the essentials, weaving together the latest theory with the experimental techniques, instrumentation, and observational methods astronomers use to study high-energy radiation from space.

Aging is characterized by the decline and deterioration of functional cells and results in a wide variety of molecular damages and reduced physical and mental capacity. The knowledge on aging process is important because life expectancy is expected to rise until 2050. Aging cannot be considered a homogeneous process and includes different trajectories characterized by states of fitness, frailty, and disability. Frailty is a dynamic condition put between a normal functional state and disability, with reduced capacity to cope with stressors. (...) This geriatric syndrome affects physical, neuropsychological, and social domains and is driven by emotional and spiritual components. Sarcopenia is considered one of the determinants and the biological substrates of physical frailty. Physical and cognitive frailty are separately approached during daily clinical practice. The concept of motoric cognitive syndrome has partially changed this scenario, opening interesting windows toward future approaches. Thus, the purpose of this manuscript is to provide an excursus on current clinical practice, enforced by aneddoctical cases. The analysis of the current state of the art seems to support the urgent need of comprehensive organizational model incorporating physical and cognitive spheres in the same umbrella. (shrink)

Cybernetic governmentality weakens the capacity of resistant subjectivities to struggle against neoliberal rationality because digitalized subjectivation processes are constantly pushed towards the logics of the market and into codifications of competitive evaluation. Despite the potential for new forms of collectivity contained in the concept of virtuality, technological evolution has disseminated a systemic form of digitality that operates not through collective procedures but through subjective-individualistic ones. Hence arises a danger that was indicated by Deleuze decades ago: that of confusing the virtual (...) with the possible. By constructing a genealogy that is built around Pierre Levy’s optimistic representation of cyberspace, Bernard Stiegler’s work on the contemporary disenchantment of the computerized world, Baudrillard’s metaphysics of code and Antoinette Rouvroy’s analysis of algorithmic governmentality, we will demonstrate that digitality is between us and that this amounts to an irreversible fact entailing a critical confrontation with its current manifestation.

Fulvio Tessitore publishes 17 letters which G. Nencioni wrote to him from 1980 to 2003. They prove the friendship and the community of interests between Piovani, Nencioni and Tessitore, as well as their shared love for the city of Naples, critical and at the same time fully aware of its great cosmopolitical tradition.
