Dalla morte la vita. Osservazioni intorno alla sacralità del cibo

2022

Since the appearance of Homo erectus, the consumption of meat has been constitutive of human life. Food is sacred because it is derived from the death of other living beings, but depriving these of life constitutes an offence against the gods, so any deprivation of life must take place according to precise rules. Food represents a symbol, and the occasions of its consumption are elective moments both of mediation between the here and the hereafter and of affirmation of the social body. On this awareness, albeit with specific articulations within each culture, the relationship between human beings and gods, and between men and men, has been founded. In increasingly limited contexts, it conti…

TRANSIENT AND FREE-VIBRATION ANALYSIS OF LAMINATED SHELLS THROUGH THE DISCONTINUOUS GALERKIN METHOD

2022

This paper presents a novel formulation for linear transient and free-vibration analysis of laminated shell structures based on Interior Penalty discontinuous Galerkin (DG) methods and variable-order through-the-thickness kinematics, whose combined use allows solving the shell problem with high-order accuracy throughout both the shell thickness and the shell modelling domain. The shell geometry is described via a generic system of curvilinear coordinates using either an analytical or a NURBS-based parametrization of the shell mid surface; the formulation also allows for the presence of cut-outs, which are implicitly represented by means of a level set function. After deriving the governing …

Perdersi. Note sul Labirinto

2022

The paper is inspired by a conversation of its author with Sandro Man- cini. Through a series of self-biographical notes, it tries to examine the topological gure of the labyrinth in some of its main mythical- symbolic, mathematical and conceptual articulations. Starting from a famous essay by Italo Calvino, i.e. La s da al labirinto, it seeks in par- ticular to discuss the works of Pierre Rosenstiehl, mathematician and philosopher to whom we owe some of the most re ned analyses on the subject of labyrinth. In the conclusions, after some other short intro- spective remarks, one aims at raising the necessity of more systematic and deepened investigations about this subject.

Tracking cruise passengers' consumption: An analysis of the relationships between onshore mobility and expenditure

2022

This paper analyzes the relationships between the spatial behaviour and destination expenditures of cruise tourists by integrating customer surveys and GPS tracking technology. Based on data collated in 2018 and 2019 in Copenhagen, cruise passenger expenditure was modelled via logistic regression, using socio-demographic characteristics and mobility-related variables. In order to map the spatial behaviour and the key characteristics of the itinerary followed, tracking data were synthesized into meaningful mobility variables. An analysis of stops was performed to identify locations with the potential highest expenditure density. The results indicated that spatial movement and, in particular,…

Cross-culturally approaching the cycling behaviour questionnaire (CBQ) : Evidence from 19 countries

2022

Given different advances in applied literature, risky and positive behaviours keep gaining ground as key contributors for riding safety outcomes. In this regard, the Cycling Behaviour Questionnaire (CBQ) represents one of the tools available to assess the core dimensions of cycling behaviour and their relationship with road safety outcomes from a behavioural perspective. Nevertheless, it has never been psychometrically approached through a cross-cultural perspective. Therefore, this study aimed to perform the cross-cultural validation of the CBQ, examining its psychometric properties, reliability indexes, validity insights and descriptive scores in 19 countries distributed across five regio…

Lacune. Una rilettura delle "Affinità elettive" di J. W. Goethe

2022

Possiamo affermare che lo spatial turn nella teoria letteraria, oggi si è definitivamente compiuto. Gli studi su letteratura e geografia, su letteratura e spazio, su letteratura e cartografia fanno bella mostra di sé nelle biblioteche di tutto il mondo. Ne sono derivati innumerevoli vantaggi sul piano di una teoria letteraria sensibile ai cultural turns: l’emancipazione della critica letteraria dalla sua irriducibile testolatria – necessaria in particolare dopo la sbornia decostruzionista – il contenimento del suo etnocentrismo e del suo eurocentri- smo, il riposizionamento della discorsività nei saperi e nelle prassi geografiche, lo sviluppo di modelli performativi nell’analisi letteraria,…

Consequences of personalized product recommendations and price promotions in online grocery shopping

2022

Shopping convenience can be turned into a competitive advantage for online grocery retailers. Consequently, we study how personalized product recommendations (recommendation agents) and price promotions (algorithmic pricing) compensate for the negative impact that consumer's perceived cognitive effort causes on loyalty. By default, the relationship from perceived cognitive efforts to attitudinal and behavioral loyalty is negative, yet these results demonstrate that personalized price promotions lessen the negative impact, while personalized product recommendations do not have such an influence. The findings contribute to a better understanding of personalized marketing activities in today's…

2022

The Madonie district, one of the 72 pilot areas of the National Strategy for Inner Areas in Italy in the center of Sicily, is composed by 21 municipalities that really have a great potential, due to their historical background and natural landscape, but it needs new strategies to emerge. Many people from northern cities have returned to their home villages in recent years, to live and work, but they have not found some important and necessary services as there are in smart cities, and to date, these villages do not adopt smart strategies. Many changes need to be made, one solution is to transform them into smart villages through rehabilitation, such as improving the historic center with str…

Transmission Optimization and Resource Allocation for Wireless Powered Dense Vehicle Area Network With Energy Recycling

2022

The wireless-powered communication paradigm brings self-sustainability to the on-vehicle sensors by harvesting the energy from radiated radio frequency (RF) signals. This paper proposes a novel transmission and resource allocation strategy for the scenario where multiple wireless powered vehicle area networks (VAN) co-existed with high density. The considered multi-VAN system consists of a remote master access point (MAP), multiple on-vehicle hybrid access points (HAPs) and sensors. Unlike previous works, we consider that the sensors can recycle the radiated radio frequency energy from all the HAPs when HAPs communicate with MAP, so the dedicated signals for energy harvesting (EH) are unnec…

Servizi bancari essenziali: il conto corrente

2022

The work proposes an analysis of the various tools that can be invoked to bridge some frictions of the credit system in areas where the banking "service" is characterized by essentiality, such as in the case of bank account. The inefficiency of the traditional code regulations emerges with particular evidence when the recourse to banking intermediation is imposed by specific rules functionality to public interests, as in case of imposed virtual currency payments. The incidence of the cost of the service, often not adequately remunerated by the price, can cause an indiscriminate selection of customers, permitted by contractual rules that authorize the end of the relationship without requirin…

The pivotal role of students’ absorptive capacity in management learning

2022

Within a research context dominated by an increasing interest in innovative learning method- ologies in management education, an individual’s capacity to establish links between existing and new knowledge, that is, absorptive capacity (AC), has been surprisingly neglected in management (higher) education inquiry. This study helps to close this gap by investigating the role of management students’ AC on their academic performance. The study also examines the moderating effect on this relationship of using traditional learning methodologies (such as lectures), innovative learning methodologies (such as interacting with digital platforms), and having a cooperative climate in the classroom. Sec…

SYNTHESIS OF HETEROCYCLES IN NON-CONVENTIONAL MEDIA: THE CASE OF IONIC LIQUIDS

2022

The synthesis of heterocycles is a prominent feature of organic chemistry, due to the enormous importance of such compounds in fields like medicinal or industrial chemistry. In the effort of improving their synthesis, the nature of the solvent plays a pivotal role. In this context, the use on non-conventional solvent like ionic liquids can determine significant improvements reaction outcomes, sustainability of the process, and possibility to be coupled with non-conventional synthetic methodologies, like ultrasounds or microwave irradiation. In this chapter, we present a bird’s-eye view on recent examples of the application of ionic liquids as solvents or catalysts, evidencing, whenever poss…

Nutrient recovery from wastewater treatment by ultrafiltration membrane for water reuse in view of a circular economy perspective

2022

The study aims to recover nitrogen from wastewater by employing ultrafiltration membrane in water reuse for agriculture purpose. To such aim, a new reclaimed water quality index (RWQI) is proposed and applied including an innovative protocol for its assessment. Specifically, the influence of filtration and backwashing times for an ultrafiltration system aimed to nutrient recovery has been analyzed. The final goal was to pin down the trade-off between operation costs and effluent quality. Results show that backwashing time play a crucial role in reducing the operation costs; indeed, low values (i.e., 0.5 min) lead to an increase in the number of required chemical cleanings and consequently o…

Then, the article will shortly engage wit…

Violation-mitigation-based method for PV hosting capacity quantification in low voltage grids

2022

Hosting capacity knowledge is of great importance for distribution utilities to assess the amount of PV capacity possible to accommodate without troubling the operation of the grid. In this paper, a novel method to quantify the hosting capacity of low voltage grids is presented. The method starts considering a state of fully exploited building rooftop solar potential. A downward process is proposed—from the starting state with expected violations on the grid operation to a state with no violations. In this process, the installed PV capacity is progressively reduced. The reductions are made sequentially and selectively aiming to mitigate specific violations: nodes overvoltage, lines overcurr…

Interactive decision support and trade-off analysis for sustainable forest landscape planning under deep uncertainty

2022

Sustainable environmental management often involves long-term time horizons and multiple conflicting objectives and, by nature, is affected by different sources of uncertainty. Many sources of uncertainty, such as climate change or government policies, cannot be addressed using probabilistic models, and, therefore, they can be seen to contain deep uncertainty. In this setting, the variety of possible future states is represented as a set of scenarios lacking any information about the likelihood of occurring. Integrating deep uncertainty into multiobjective decision support increases complexity, calling for the elaboration of appropriate methods and tools. This paper proposes a novel intera…

Experimental characterization of variable-speed packaged rooftop units in presence of evaporator fouling

2022

Variable-speed packaged rooftop units have been increasingly adopted in the commercial sector. If not properly maintained, the fouling of heat exchangers and the improper refrigerant charge could increase energy consumption. In this work, the response of variable-speed rooftop units to evaporator fouling is investigated based on experiments on a variable-speed 17.5 kW rooftop unit. A novel testing procedure is proposed, aimed at covering a broad range of operating conditions by a reduced number of tests. Two opposite cases were investigated: (i) even in presence of fouling, the controller can restore the required cooling capacity, and (ii) the intensity of the fouling does not allow the con…

This short review summarizes most analytical methods to detect and quantify PAHs and PAEs in house dust used as a passive sampler. The objective of house dust analysis is to identify the presence, amount and distribution of specific hazardous substances in confined spaces and, if possible, to identify their sources. Household dust and the compounds present in it can enter the human body by in…

Highly cited educational technology journal articles: A descriptive and critical analysis

2022

Citations are valuable capital in the academy as the number of citations is the most frequently used indicator in evaluating the quality of papers, journals, researchers, and universities. Thus, the characteristics of highly cited articles (HCA) have become a common research topic but the approach has been mainly descriptive with no profound critical reflection of what kind of research is cited, where the research is from, where the research is published, and what do these things mean for edtech research. This paper contributes to this need by providing a descriptive and critical analysis of 200 highly cited articles from 10 edtech journals. To summarize the key findings, a ‘typical’ edtech…

Synthesis and Antioxidative Properties of 1,2,3,4-Tetrahydropyridine Derivatives with Different Substituents in 4-Position

2022

Natural products are an excellent source of inspiration for the development of new drugs. Among them, betalains have been extensively studied for their antioxidant properties and potential application as natural food dyes. Herein, we describe the seven-step synthesis of new betalamic acid analogs without carboxy groups in the 2- and 6-position with an overall yield of ~70%. The Folin–Ciocalteu assay was used to determine the antioxidant properties of protected intermediate 21. Additionally, the five-step synthesis of betalamic acid analog 35 with three ester moieties was performed. Using NMR techniques, the stability of the obtained compounds towards oxygen was analyzed.
