Spiritus movens. Biografia di don Bernardo Antonini (1932-2002)
No full text«Italiano di nascita, era diventato russo di cuore. Amava la Russia con tutto il suo grande cuore aperto a tutti: cattolici, ortodossi, credenti e non credenti. Le sue capacità intellettuali e organizzative, la sua profonda spiritualità e preghiera erano a servizio dell’amore per tutti. Speranza contro ogni speranza, instancabile lavoro giorno e notte hanno meritato a lui una grande riconoscenza del popolo russo. Bastava dire “Don Bernardo” e tutti sapevano di chi si parlava. Personalmente sono molto grato a lui, mio più stretto collaboratore. Lui è stato l’uomo della Provvidenza, giusto per il tempo giusto, messo da Dio al momento opportuno. Lo ringrazio di tutto, chiedo scusa, perché forse noi non sempre siamo stati in grado di capire i suoi piani, pensieri e progetti; il tempo però ha mostrato che aveva ragione».Parole pronunciate da mons. Tadeusz Kondrusiewicz, già arcivescovo metropolita della Madre di Dio a Mosca, nella cattedrale di Verona, alla chiusura dell’Inchiesta diocesana sulla vita, le virtù eroiche e la fama di santità e di segni di mons. Bernardo Antonini (20 ottobre 2013).Gli autori sono entrambi docenti dell’Università degli Studi di Verona. Stefano Aloe (Napoli, 1972) è slavista e storico della letteratura russa; Edoardo Ferrarini (Verona, 1972) è docente di letteratura latina medievale. Chiamati a far parte della speciale Commissione di periti storici nell’Inchiesta diocesana (2009-2013), hanno continuato anche negli anni seguenti ad approfondire lo studio della documentazione archivistica sulla figura di don Bernardo. I risultati di questa ricerca giungono ora alla pubblicazione con la presente biografia che, senza rinunciare alla forma e alla sostanza di uno studio storico-critico, ambisce a raggiungere e interessare un pubblico più ampio

Total Coloring and Total Matching: Polyhedra and Facets
No full textA total coloring of a graph G = (V, E) is an assignment of colors to vertices and edges such that neither two adjacent vertices nor two incident edges get the same color, and, for each edge, the end-points and the edge itself receive different colors. Any valid total coloring induces a partition of the elements of G into total matchings, which are defined as subsets of vertices and edges that can take the same color. In this paper, we propose Integer Linear Programming models for both the Total Coloring and the Total Matching problems, and we study the strength of the corresponding Linear Programming relaxations. The total coloring is formulated as the problem of finding the minimum number of total matchings that cover all the graph elements. This covering formulation can be solved by a Column Generation algorithm, where the pricing subproblem corresponds to the Weighted Total Matching Problem. Hence, we study the Total Matching Polytope. We introduce three families of nontrivial valid inequalities: vertex-clique inequalities based on standard clique inequalities of the Stable Set Polytope, congruent -2 k 3 cycle inequalities based on the parity of the vertex set induced by the cycle, and even-clique inequalities induced by complete subgraphs of even order. We prove that congruent -2 k 3 cycle inequalities are facet-defining only when k = 4 , while the vertex-clique and even-cliques are always facet-defining. Finally, we present preliminary computational results of a Column Generation algorithm for the Total Coloring Problem and a Cutting Plane algorithm for the Total Matching Problem.(c) 2022 Elsevier B.V.

Полюбивший Россию. Биография дона Бернардо Антонини (1932-2002)
No full text«Родом итальянец, русский сердцем, дон Бернардо любил Россию всей своей душой, открытой для всех: католиков, православных, верующих и неверующих. Его интеллект и организаторские таланты, глубокая духовность и молитва помогали ему в его служении, которое он осуществлял с любовью ко всем людям. Своей способностью надеяться вопреки всему, работать без устали днем и ночью он заслужил особое признание русского народа. Достаточно было произнести: «Дон Бернардо», - и все понимали, о ком шла речь. Я очень ему благодарен, как моему самому близкому сотруднику. Он был именно тем человеком, которого Провидение послало в нужное время, которого Бог дал в подходящий момент. Благодарю его за все, прошу прощения за то, что, быть может, мы не всегда могли понять его планы, мысли и проекты, но время показало, что он был прав
Soil and ecosystem services: Current knowledge and evidences from Italian case studies
No full textSoil management is fundamental to all agroecosystems and affects ecosystem processes that are involved in the provision of multiple ecosystem services (ES). Agricultural soils are the habitat for key functional organisms which collectively as soil biota contribute to soil ES provision: supporting biomass production and nutrient cycling, regulating of climate, water and biological control of pests and diseases. As result of an increased awareness on the importance of soil ES, soil science is playing an active role in informing the ecological intensification of agriculture. In this study, the lessons learned from Italian case studies on the usefulness of using a soil health assessment framework based on multiple soil ES are presented. Soil health as an integrative property of agroecosystem management can be evaluated with a set of physical, chemical, and biological indicators representative of essential soil ES. This is the basis of the Soil Management Assessment Framework (SMAF) (Andrews et al., 2004) and it is based on a three-step process that includes indicator selection, indicator interpretation, and integration into a final index. In northern Italy, several field trials have been set up to assess multiple ES provision from bioenergy crops cultivated on marginal conditions and from contrasting vegetable cropping systems. These studies revealed how the use of a comprehensive soil health assessment framework can help: (1) to identify the best soil management practices that deliver multiple ES and (2) to support resource-efficient production. Beyond academic research, the integration of multiple indicators of soil health within the assessment of agroecosystems sustainability is essential if we want to promote ecological intensification of food and bioenergy production
Measurement of total and extractable enzyme activity from soil and decomposing litter
No full textThe total and extractable activities of the enzymes β-glucosidase (bgluc), cellobiosidase (cell), xilanase (xil), chitinase (chit), leucine aminopepditase (leu) and acid phosphomonoesterase (acP) were determined in soil and decomposing litter of miscanthus (Miscanthus x giganteus L.) and black locust (Robinia pseudoacacia L.). The objective was to quantify the enzyme-specific extractability of a desorption-based fluorometric enzyme assay and whether the extractability is affected by soil and litter type. Soil and litter samples were extracted in 2mL eppendorf tubes with glass/ceramic beads and lysozyme solution. Soil suspensions were incubated in a stirring device and aliquotes of the supernatant were dosed in 384-well microplates after centrifugation to determine total activity. The extractable activity was measured on the supernatant taken from incubated suspension. Extractability of soil enzymes (as % of the total activity) was on average as follows: bgluc (3%), cell (11 %), xil (4%), chit (8%), leu (44%) and acP (13%). A significant effect of SOC and FBC/MBC on acP and leu extractability was observed. Extractability of litter enzymes, instead, was on average as follows: bgluc (25%), cell (10 %), xil (19%), chit (16%), leu (31%) and acP (28%). A significantly higher extractability for chit and leu was observed in miscanthus litter (C/N: 71, Lignin/N: 32) compared to black locust litter (C/N: 17, Lignin/N: 6). We also observed that extractability in both litter types increase significantly in bgluc (+405%), xil (+242%), cell (+217%) and acP (+454%) during the late stage of decomposition. This method enabled the quantification of total and extractable activities of several soil/litter hydrolytic enzymes

Executive remuneration standards and the “conformity gap” at controlled corporations
No full textIn this paper we analyze the relationship between conformity to executive
remuneration standards, corporate ownership, and the level and structure of
CEO compensation for large European listed companies in the years 2007
and 2010. We show that controlled corporations conform to executive
remuneration standards less than widely held firms. We also show that
weaker compliance is associated with lower CEO pay and more cash-based
incentive structures. We interpret this “conformity gap” from the perspective
of individual firms and from a societal perspective, with the aim to contribute
to frame the policy questions concerning executive pay at controlled
corporations. Different policy implications depend on whether the conformity
gap reflects a lower need for managerial incentives, given the monitoring by
controlling shareholders, or the latter’s willingness to extract private benefits
of control. We argue in this paper that the former hypothesis prevails, so that
regulators should abstain from increasing the level of enforcement of
executive remuneration standards
Who is the author of the 1876 Stefano manuscript?
Get PDFFor over one hundred years the Stefano manuscript was a private document in the possession of the Baccich family and descendants. It told a story of the 1875 Stefano shipwreck as narrated by the shipwreck survivor and the founding family patriarch Miho Baccich. In these circumstances the question of authorship of the manuscript was immaterial and did not arise as an issue. However, with the publication of the manuscript the author‟s name, or names, need to be formally attributed to it. It turns out that this is not such a clear-cut matter.
As we shall see, all informed sources attributed the authorship, and the ownership, of the manuscript to Miho Baccich. But the manuscript itself was written by Canon Stjepan Skurla – a priest from Miho‟s hometown of Dubrovnik. The question then arises: should Skurla also be considered as an author of the manuscript, or, even as the sole author (as some would have it)
