Che ne è dell'equilibrio? Gli economisti alle prese con la realtà delle cose
No full textDietro la realizzazione dei profitti - l'equilibrio economico cui aspirano i capitalisti che appare unico, stabile e ottimo - sta lo scandalo dello sfruttamento.Behind the generation of profits—the economic equilibrium to which capitalists aspire, which appears unique, stable, and optimal—lies the scandal of exploitation
Balancing excellence and diversity in economics: rethinking research-funding allocation in the age of mainstream pluralism
No full textThis paper offers a qualitative discussion about the possibility of achieving a more balanced relationship between excellence (via meritocracy) and pluralism (via diversity) in the allocation of public funding in economic research. The historical and methodological transformations that have shaped the discipline call for abandoning a strict meritocratic approach to funding in favour of supporting more varied research projects that still meet high standards of scientific research. Such an approach would help avoid distorting the endogenous evolution of economics, encouraging the development of new alternative research programs and fields alongside the traditional mainstream orthodox neoclassical perspective. Accordingly, we argue that the historical and methodological evolution of a discipline should be considered among the possible criteria policymakers adopt for funding research allocation. To support this argument, we first examine how mainstream pluralism has progressively counterbalanced economic imperialism, thus calling for a more inclusive definition of meritocracy that fosters major diversity also in funding allocation. We then offer a Schumpeterian interpretation of advantages and limitations of both strict meritocratic and pluralistic approaches to funding. The paper concludes with some policy recommendations to promote diversity in research funding as a means to reduce inequalities in academic contexts, particularly within the so-called “dismal science”
Topic tasseographeR: An interactive R‐Shiny application to interpret and validate topic models
No full textInterpreting and validating topic-model outputs remains a persistent challenge in text-as-data research. We introduce Topic tasseographeR, an R Shiny application that supports topic interpretation and validation through post-hoc dictionary-based scoring. The app computes topic content and topic function scores by combining established lexical resources with topic–word and document–topic distributions. Designed to be model-agnostic, Topic tasseographeR integrates seamlessly with existing topic-modelling workflows and enables both deductive validation and abductive topic labelling. By leveraging validate dictionary-based methods, the software provides a complementary alternative to human- and machine-in-the-loop topic interpretation and validation approaches
The Role of High-Frequency Wall Vibrations in Adverse Vascular Remodeling of Arteriovenous Fistula for Hemodialysis
Full text linkBackground: Despite progress in research, the mechanobiological mechanisms behind adverse vascular remodeling and failure in arteriovenous fistulae (AVF) for hemodialysis remain unclear. The aim of this investigation is to assess the association between flow-induced vascular wall vibrations and adverse vascular remodeling in AVFs. Methods: Six end-stage kidney disease patients with native distal radio-cephalic AVF were monitored for 1 year with magnetic resonance imaging and Doppler ultrasound examinations. Patients were divided based on AVF outcomes: two maintained proper AVF patency and four developed complications (two venous stenoses and two excessive dilatations). Patient-specific fluid-structure interaction simulations were performed at different time points. Results: Before vascular remodeling, stenotic AVFs exhibited two dominant frequency bands, between 45 and 100 Hz, while excessively dilated AVFs exhibited a single band at 50 Hz. Before the onset of remodeling, patients with complications exhibited significantly higher vibration amplitude (22.5 ± 5.8 μm vs. 6.6 ± 2.0 μm, p < 0.01) and high-pass strain ((1.30 ± 0.35)∙10-3 vs. (0.30 ± 0.10)∙10-3, p < 0.01) than those with proper patency. Significant differences in vibration amplitude and high-pass strain were observed between patients with proper patency and those with stenosis (p < 0.001 and p < 0.01, respectively), and in high-pass strain between patients with preserved patency and those with excessive dilatation (p < 0.01). Conclusions: Specific vibration frequencies and amplitude levels appear to be associated with distinct types of vascular remodeling, indicating they could potentially be biomarkers for AVF surveillance

Full text linkMeditation Transcending Signs: Seven Concepts for a Buddhist Psychosemiotics
Full text linkThis paper aims to provide an in-depth and detailed overview of the relationship between language and cognition in Pāli Buddhist texts. These reflections will touch on several fundamental themes, such as the role of signs in structuring cognitive processes and semiosis as a force linked to the proliferation of concepts and percepts, whose organization underlies the constitution of a shared and partly subjective “world”. The paper will engage with linguistics, semiotics, and biosemiotics in order to acquire a vocabulary capable of better understanding the Buddhist reflections on these issues, and, where possible, it will also offer a genealogical inquiry that explains why the theme of language takes on the pivotal role it holds in Pāli Buddhism
