He Is All American Now”: Italian–Americans in the Italian Campaign of World War II

2022

This chapter aims to analyze the case of the Italian–Americans' participation in World War II. It is an interesting case study to focus on issues connected to the processes of constructing multifaceted identities that characterize ethnicity. In 1943, in view of the invasion of Italy, the US asked Italian–Americans to fight against their ancestor country. Nonetheless, they were encouraged to exploit their idealistic roots and their “ethnical” competence to facilitate a “good occupation.” Biographies of Italian–Americans that were in Italy will help us to examine the interplay between Italianness and Americanization in war experience.

On the usage of joint diagonalization in multivariate statistics

2022

Scatter matrices generalize the covariance matrix and are useful in many multivariate data analysis methods, including well-known principal component analysis (PCA), which is based on the diagonalization of the covariance matrix. The simultaneous diagonalization of two or more scatter matrices goes beyond PCA and is used more and more often. In this paper, we offer an overview of many methods that are based on a joint diagonalization. These methods range from the unsupervised context with invariant coordinate selection and blind source separation, which includes independent component analysis, to the supervised context with discriminant analysis and sliced inverse regression. They also enco…

Investigation of hydrogen and deuterium impact on the release of tritium from two-phase lithium ceramics under reactor irradiation

Natural Course, Clinical Profile, and Treatment Strategies for Cerebral Cavernous Malformations

2022

A large body of evidence has suggested that the natural biology for symptomatic cerebral cavernous malformations (CCMs) is dynamic. These lesions exhibit a temporal clustering epiphenomenon and usually manifest with multispectral clinical patterns, the most relevant being hemorrhagic and seizurogenic events. Most patients with cerebral cavernous malformations are asymptomatic, and the lesions are detected as incidentalomas. However, association with the CCM3 gene, Zabramski type I and II lesions, and brainstem location have the propensity to increase the bleeding events. The rebleeding risk is 20%/year per lesion, which supports the need for surgical strategies for brainstem cavernous malfo…

The Impact of the COVID-19 Emergency on the Quality of Life of the General Population

2022

COVID-19 is a pandemic that has forced many states to declare restrictive measures in order to prevent its wider spread. These measures are necessary to protect the health of adults, children, and people with disabilities. Long quarantine periods could cause an increase in anxiety crises, fear of contagion, and post-traumatic stress disorder (frustration, boredom, isolation, fear, insomnia, difficulty concentrating). Post-traumatic stress disorder (PTSD) is a condition that can develop in subjects who have been or have witnessed a traumatic, catastrophic, or violent event, or who have become aware of a traumatic experience that happened to a loved one. In fact, from current cases, it emerge…

State of the Art and Future Direction in Diagnosis, Molecular Biology, Genetics, and Treatment of Brain Arteriovenous Malformations

2022

Brain arteriovenous malformations (bAVMs) are uncommon and represent a heterogeneous group of lesions. Although these 2 facts have delayed research on this topic, knowledge about the pathophysiology, diagnosis, and treatment of bAVMs has evolved in recent years. We conducted a review of the literature to update the knowledge about diagnosis, molecular biology, genetic, pathology, and treatment by searching for the following terms: "Epidemiology AND Natural History," "risk of hemorrhage," "intracranial hemorrhage," "diagnosis," "angiogenesis," "molecular genetics," "VEGF," "KRAS," "radiosurgery," "endovascular," "microsurgery," or "surgical resection." Our understanding of bAVMs has signific…

Catarsi ed Ethos. La musica tra formazione del carattere e cura dei mali nella Grecia antica

2022

Nella Grecia antica la musica è presenza costante e riguarda tutti gli aspetti del sapere. L’idea di un influsso esercitato sull’uomo, e persino sulla sua salute, trova espressione nella nozione di catarsi e nella dottrina dell’ethos, secondo cui la musica esplica un’azione psicagogica in base alle harmoníai («scale musicali») seguite dalle composizioni, e agli strumenti usati. A partire dai riti, la catarsi entra nella riflessione di Platone e di Aristotele. Nel De musica di Aristide Quintiliano, l’analisi della capacità della musica di influire sull’anima si affianca alla speculazione sulle harmoníai e apre la strada alla comprensione del suo influsso sull’indagine medica, definendo nel c…

The Philosophical Underpinning of Athlete Lifestyle Support : An Existential-Humanistic Perspective

2022

This study aims to highlight how an existential-humanistic perspective can inform athlete support and in doing so, emphasise the importance of explicating the philosophical underpinnings of athlete lifestyle support. Drawing on applied experience with elite youth cricketers over a twelve-month period, ethnographic data was collected through the observation, maintenance of case notes and a practitioner reflective diary. Based on thematic analysis (Braun & Clarke, 2006), we created three non-fictional vignettes that we use to illustrate how existential-humanistic theorising can inform lifestyle support. We discuss the implications of this professional philosophy in terms of considerations for…

Understanding phenolic acids inhibition of α-amylase and α-glucosidase and influence of reaction conditions

2022

Phenolic acids are involved in modulating the activity of starch digestive enzymes but remains unclear if their interaction with enzymes or starch is governing the inhibition. The potential inhibition of nine phenolic acids against α-amylase and α-glucosidase was studied applying different methodologies to understand interactions between phenolic acids and either enzymes or substrates. Vanillic and syringic acids were prone to interact with α-amylase requiring low half-maximum inhibitory concentration (IC50) to inhibit starch hydrolysis. Nevertheless, the initial interaction of phenolic acids with starch somewhat obstructed their interaction with starch, requiring 10 times higher IC50, with…

Multiphoton process investigation in silica by UV femtosecond laser

2022

We investigated the interaction processes between high intensity femtosecond ultraviolet laser pulses and amorphous silica, leading to permanent refractive-index changes that are at the basis of advanced manufacturing for photonics devices. The experiment, carried out as a function of the laser power, improves our understanding on the strong-field ionization process by the monitoring of the 1.9 eV and 2.65 eV emissions, related to nonbridging oxygen hole centers and self-trapped exciton, respectively, induced in the exposed glass region. Our results clearly proved that the UV laser light band-to-band absorption is allowed in the multiphoton ionization limit, whose consecutive relaxation lea…

The Swedish dilemma - the almost exclusive use of APPswe-based mouse models impedes adequate evaluation of alternative β-secretases.

2022

Abstract Alzheimer's disease (AD) is the most common form of dementia, however incurable so far. It is widely accepted that aggregated amyloid β (Aβ) peptides play a crucial role for the pathogenesis of AD, as they cause neurotoxicity and deposit as so-called Aβ plaques in AD patient brains. Aβ peptides derive from the amyloid precursor protein (APP) upon consecutive cleavage at the β- and γ-secretase site. Hence, mutations in the APP gene are often associated with autosomal dominant inherited AD. Almost thirty years ago, two mutations at the β-secretase site were observed in two Swedish families (termed Swedish APP (APPswe) mutations), which led to early-onset AD. Consequently, APPswe was …

Governance, foreign aid, and Chinese foreign direct investment

2022

This article examines how Chinese foreign aid interacts with the quality of the host country's governance in shaping Chinese state-owned enterprises' (CSOEs') foreign direct investment (FDI) in Africa. By analyzing the firm-level greenfield FDI data of CSOEs between 2003 and 2014 and distinguishing between China's official development assistance and less concessional forms of Chinese foreign aid, we reveal two main findings. First, the quality of the host country's governance negatively affects CSOEs' FDI. Second, other official aid and loans from China negatively moderate the relationship between the quality of the host country's governance and FDI by CSOEs. Specifically, the tendency for …

Fibred-categorical obstruction theory

2022

Abstract We set up a fibred categorical theory of obstruction and classification of morphisms that specialises to the one of monoidal functors between categorical groups and also to the Schreier-Mac Lane theory of group extensions. Further applications are provided to crossed extensions and crossed bimodule butterflies, with in particular a classification of non-abelian extensions of unital associative algebras in terms of Hochschild cohomology.

A Software Tool For Sparse Estimation Of A General Class Of High-dimensional GLMs

2022

Generalized linear models are the workhorse of many inferential problems. Also in the modern era with high-dimensional settings, such models have been proven to be effective exploratory tools. Most attention has been paid to Gaussian, binomial and Poisson settings, which have efficient computational implementations and where either the dispersion parameter is largely irrelevant or absent. However, general GLMs have dispersion parameters φ that affect the value of the log- likelihood. This in turn, affects the value of various information criteria such as AIC and BIC, and has a considerable impact on the computation and selection of the optimal model.The R-package dglars is one of the standa…

Rethinking vineyard ground management to counter soil tillage erosion

2022

Tillage erosion is a relevant process of soil redistribution in sloping arable land, but little research has analysed the effect of shallow tillage on soil erosion in vineyards. The goal of this study was to quantify the soil tillage effect on soil translocation and erosion at the territorial level in a large vineyard area in Sicily. The soil loss and soil erosion tolerance limits were compared to identify the vineyards with a high risk of soil degradation. An alternative management scenario to traditional tillage was proposed to evaluate the effectiveness of the best management practices on soil conservation. The experimental trials were conducted in 14 vineyards with different slopes and …

Resilience in Informal Caregivers of People Living with Dementia in the Face of COVID-19 Pandemic-Related Changes to Daily Life

2022

Abstract. Informal caregivers of people living with dementia (PwD) are at increased risk for the development of stress-related physical and mental illness. Nevertheless, because of differing resilience, they show interindividual differences in their ability to cope. Particularly during the COVID-19 pandemic, with the associated pandemic control measures and pandemic-related changes to daily life, resilience might be further challenged, and stress might consequently increase. Therefore, we review the evidence on informal caregivers’ experience during the COVID-19 pandemic regarding effects of the pandemic control measures on (a) the caregiver’s health, (b) the care recipient’s health, (c) th…

Exposure to retene, fluoranthene, and their binary mixture causes distinct transcriptomic and apical outcomes in rainbow trout (Oncorhynchus mykiss) …

2022

Polycyclic aromatic hydrocarbons (PAHs) are widely spread environmental contaminants which affect developing organisms. It is known that improper activation of the aryl hydrocarbon receptor (AhR) by some PAHs contributes to toxicity, while other PAHs can disrupt cellular membrane function. The exact downstream mechanisms of AhR activation remain unresolved, especially with regard to cardiotoxicity. By exposing newly hatched rainbow trout alevins (Oncorhynchus mykiss) semi-statically to retene (32 µg l−1; AhR agonist), fluoranthene (50 µg l−1; weak AhR agonist and CYP1a inhibitor) and their binary mixture for 1, 3, 7 and 14 days, we aimed to uncover novel mechanisms of cardiotoxicity using a…

The invasive cyanobacteria Raphidiopsis raciborskii a toxin-producing and bloom-forming species affecting local biodiversity and ecosystem services is currently expanding its range across Europe. We used species distribution models (SDMs) and regional bioclimatic environmental variables, such as temperature and precipitation, to identify suitable areas for the colonization and survival of R. raciborskii, with special focus on the geographic extent of potential habitats in Northern Europe. SDMs predictions uncovered areas of high occurrence probabilit…

Inhibition of bacterial virulence factors of foodborne pathogens by paprika (Capsicum annuum L.) extracts

2022

Abstract Capsicum annuum extracts of different polarities were tested for their antimicrobial, antibiofilm, and anti-Quorum sensing (QS) activity against several pathogenic microorganisms and possible toxic effects using an in vivo model (Galleria mellonella L.). Hexane (HE) and Chloroform extract (CE) were the most active in inhibiting biofilm formation of the eight bacteria tested, with inhibition percentages between 22 and 88% for a concentration of 100 μg/mL. These extracts were potent inhibitors of Staphylococcus aureus biofilm, and microscopy analysis confirmed a significant reduction in adhered cells. Moreover, polystyrene surfaces coated with these extracts decreased Staph. aureus a…
