Between Public History of Education and identity dissemination: the role of Italian American Museums
No full textThis paper explores the role of Italian American museums as spaces of mediation between Public History of Education and identity transmission. Through a historical-educational and museological analysis, it highlights how these institutions have
transformed exhibition spaces from mere containers of objects into narrative and participatory tools capable of fostering processes of Heritage Education. Museums dedicated to the Italian diaspora in the United States represent emblematic cases of intercultural narration and collective memory. Storytelling practices, deeply intertwined with community dynamics and the ideological tensions inherent in ethnic representation,
raise critical questions about the educational and social role of the contemporary museum
Development of a 3D-printed food based on arrowhead (Sagittaria sagittifolia L.) byproducts: Effects of hydrocolloids on printability and post-processing performance
No full textThis study aimed to develop a 3D-printed food using arrowhead byproducts (ADBs) as an innovative food-ink. Four hydrocolloids including xanthan gum, gellan gum, guar gum, and fenugreek gum were individually added into ADBs to prepare gel inks, namely AXG, AGG, AGUG, and AFG, respectively. The microstructure, texture, and rheological properties of gel inks were comprehensively studied. The sensory properties of post-processed 3D-printed products were compared. The results showed that the addition of hydrocolloid altered the microstructure of gel inks, and further influenced their texture and rheological properties. AGG exhibited rigid gel network structure via ion cross-linking and hydrogen bond interactions; however, it was not suitable for extrusion. The addition of xanthan gum endowed the gel ink with suitable gel strength and flowability, which were in favor of the extrusion process and the 3D-printed products showed the highest printing accuracy (96.02 %). The sensory properties of post-processed 3D-printed products exhibited distinct characteristics but hydrocolloid addition showed no significant influences in the same post-processing treatment. Baking was the desirable method for imparting the 3D-printed products with appealing color, desirable hardness, and pleasant aromas. This study provides feasible strategies and insights for the valorization of arrowhead byproducts

No full textThe asparagus sector possesses considerable economic potential worldwide: demand continues to rise, yet production still falls short of fully meeting it. Within Europe, Italy ranks third in overall volume and holds a well-established lead in green-asparagus production, especially in Apulia, where the cultivated area has expanded sharply in recent years. In this context, sustainable plant-health management, crucial for organic crops in particular, moves centre stage. Across the Mediterranean basin the chief asparagus pests are the cossid moth Parahypopta caestrum (Hübner) and the chrysomelid beetle Crioceris duodecimpunctata. P. caestrum poses a growing threat in Apulia, its spread favoured by the larvae’s endophytic development in the roots, limited biological knowledge, ineffective monitoring tools and the scant availability of authorised chemical products. Because obligatory integrated pest management (IPM) cannot be applied and demand for organic asparagus continues to grow, new, sustainable and effective solutions are urgently needed. In this scenario, identifying semiochemicals, sex pheromones and host-plant volatile organic compounds (VOCs), offers promising, low-impact avenues for monitoring and control. Despite the insect’s agronomic importance, the sex pheromone of P. caestrum had never been identified before this Ph.D. project; likewise, no information was available on the ability of C. duodecimpunctata adults to detect and orient toward host-plant odours. The thesis therefore set out to identify the main intra- and interspecific semiochemicals involved in the chemical communication of Parahypopta caestrum and Crioceris duodecimpunctata, two key asparagus pests in southern Italy. The work combined chemical-analytical, electrophysiological and behavioural methods in an integrated approach consistent with IPM principles. Using gas chromatography–mass spectrometry coupled with electroantennographic detection (GC-MS-EAD), the sex pheromone of P. caestrum was identified for the first time. Four EAD-active compounds were isolated: (Z)-9-tetradecenyl acetate, (Z)-7-tetradecenyl acetate, (Z)-5-tetradecenyl acetate and (Z)-9-tetradecenol. Field trials showed that a ternary blend of the three acetates in an 85:5:10 ratio of (Z)-9-, (Z)-7- and (Z)-5-tetradecenyl acetate is significantly more attractive to males than any single component or other binary/ternary mixtures. This blend enabled the monitoring of male flight activity and paved the way for semiochemical-based control strategies. Pheromone-baited traps also allowed large-scale monitoring of P. caestrum distribution and phenology during a three-year survey (2021–2023) in many locations in Apulia and Molise. Interactions between the sex pheromone and plant VOCs were further explored by testing P. caestrum responses to volatiles emitted by Asparagus officinalis. Field trials optimised trap design and pheromone dosage, while a two-season mass-trapping experiment produced a significant reduction in cocoon density in the soil, indicating potential population suppression. The thesis likewise investigated olfactory mechanisms in adult C. duodecimpunctata of both sexes. Electroantennographic and behavioural assays showed that the beetle can perceive numerous asparagus VOCs, but only males exhibited clear attraction to certain plant odours. This behavioural dimorphism suggests an active male role in host-plant location and opens prospects for using kairomones in monitoring. Beyond asparagus and its principal pests, the doctoral work encompassed studies on other insects of agricultural and medical importance, aiming to deepen understanding of olfactory perception and the applied potential of semiochemicals. For the olive fruit fly Bactrocera oleae, electrophysiological and behavioural techniques assessed the effects of biochar-derived smoke waters and essential oils such as that of Carlina acaulis. Interactions between olfactory inhibitors and conventional attractants were explored, demonstrating that short-chain aliphatic aldehydes can markedly reduce catches in traps baited with sex pheromones or food attractants. In the post-harvest arena, the olfactory behaviour of two major stored-product pests was examined: Sitophilus oryzae, in response to volatiles from stored rice, and Stegobium paniceum in relation to VOCs from Chinese plant materials. A simplified GC-MS-EAD system was developed for insects of medical relevance and applied to females of Phlebotomus perniciosus, the principal vector of Leishmania infantum. Finally, in Philaenus spumarius the study demonstrated that males perceive and orient toward volatiles emitted by females, elucidating intraspecific chemical communication in this vector. Taken together, the studies conducted alongside the main project consolidated broad expertise in electrophysiological, chemical-analytical and behavioural techniques applied to insect olfactory ecology, contributing to innovative tools for crop protection and the sustainable management of medically significant vectors

No full textLa «poesia della scienza» di Hans Magnus Enzensberger e il legame con il Romanticismo
No full textPartendo dall’intenso e costante interesse di Enzensberger per le
scienze, il contributo mostra come del rapporto con il Romanticismo si possa trovar traccia anche nella valorizzazione della «poesia della scienza» – e nella
scienza – che Enzensberger sottolinea in modo particolare. Nel saggio
"La poesia della scienza", che conclude la raccolta degli "Elisir della scienza.
Sguardi trasversali in poesia e prosa", l’autore si muove programmaticamente
sul confine tra poesia e scienza, evidenziando una specifica e consapevole sensibilità estetica delle scienze. La poesia della scienza ci riporta così ad una formulazione che appartiene alla filosofia della natura di Novalis, rivelando una scienza consapevole della sua poeticità e quindi una specifica e consapevole affinità delle scienze con le forme estetiche di rappresentazione
Navigating human-technology dynamics: Exploring innovation resistance to smartphone apps in amusement parks
No full textThis paper offers a novel exploration of the factors influencing users' rejection of smartphone apps, focusing on the context of amusement parks. This study introduces a unique and broader framework grounded in the Innovation Resistance Theory (IRT), which includes hedonism and utilitarianism, for understanding technology resistance. Notably, this research highlights the distinct leisure dynamics impacting technology adoption in amusement parks, unlike previous studies focusing on acceptance in sectors like banking and healthcare. A mixed-method sequential design was employed to achieve the research aim: qualitative data from online focus groups informed the conceptual model, which was tested by quantitatively analyzing 362 survey responses. Partial Least Squares Structural Equation Modeling (PLS-SEM) was run to assess the model's reliability, validity, and structural relationships. The results confirmed the positive relationship between value, amenability, information, and functional risk barriers, along with perceived utilitarianism and app rejection, while perceived hedonism is negatively associated with rejection. Differently, complexity, usage, and physical risk barriers do not significantly affect the rejection of smartphone apps in amusement parks. These findings help to understand human-technology interactions in the leisure context, suggesting effective interventions that park managers can undertake to enhance the visitors' experience and the users' digital service adoption
