The Florentine archives in transition: government, warfare and communication (1289-1530 ca.)
A turning point in European administrative and documentary practices was traditionally associated, most famously by Robert-Henri Bautier, with the monarchies of the late sixteenth and early seventeenth centuries. By summarizing previous research in this field, as well as by using both published and unpublished sources, this article intends to underline an earlier process of transition connected to the development of significant new techniques for the production and preservation of documents in Renaissance Italian city-states. Focusing on the important case of Florence, the administrative uses of records connected to government, diplomacy and military needs will be discussed, and evidence will be provided that such documentary practices accelerated significantly during the so-called Italian Wars (from 1494 onwards). A particular reason of interest for Florence at this time is that a major role in the production and storage of a large quantity of state papers was played by Niccolò Machiavelli, one of the outstanding political thinkers of the age. This was especially true in connection to the new militia which he himself created in 1506. By stressing the role of information management and the importance of correspondence networks at a time of war and crisis, this article also contributes to recent scholarship which has focused on the growth of public records relating to diplomacy in Italy during the second half of the fifteenth century, as well as to a recent field of historiography which has lately gained importance: namely the ‘documentary history of institutions’
Treatment of a Femur Nonunion with Microsurgical Corticoperiosteal Pedicled Flap from the Medial Femoral Condyle
Introduction.Te vascularized corticoperiosteal fap is harvested from the medial femoral condyle and it is nourished by the articular branch of the descending genicular artery and the superomedial genicular artery. Tis fap is usually harvested as a free fap for the reconstruction of bone defects at forearm, distal radius, carpus, hand, and recently at lower limb too. Case Report. A 50-year-old Caucasian man referred to our department for hypertrophic nonunion of the distal femur, refractory to the conservative treatments. Te frst surgical choice was the revision of the nail and the bone reconstruction with a corticoperiosteal pedicled fap from the medial femoral condyle. We considered union to have occurred 3.5 months afer surgery when radiographs showed bridging of at least three of the four bony cortices and clinically the patient was able to walk with full weight bearing without any pain. At the last follow-up (25 months), the patient was completely satisfed with the procedure. Discussion. Te corticoperiosteal fap allows a faster healing of fractures with a minimal morbidity at the donor site. We suggest that the corticoperiosteal pedicled fap graf is a reliable and efective treatment for distal femur nonunion
Mergers and Acquisitions Between Mutual Banks in Italy :An analysis of the effects on performance and productive efficiency
The paper is aimed at testing the hypothesis that the M&A wave over the past ten years has increased the level of efficiency of co-operative credit banks (CCBs), both in terms of overall performance and productive efficiency. The logical development is hinged on two steps: 1) an explorative analysis which is based on the observation of balance sheet ratios by quantiles, 2) a DEA application for estimating productive efficiency scores. The analysis refers to 94 CCBs which have been involved in M&As over the period 1995-1998 and is carried out on both merged and non-merged banks, either before concentration or in the subsequent years.
Self-presentation and emotional contagion on Facebook: new experimental measures of profiles' emotional coherence
Social Networks allow users to self-present by sharing personal contents with
others which may add comments. Recent studies highlighted how the emotions
expressed in a post affect others' posts, eliciting a congruent emotion. So
far, no studies have yet investigated the emotional coherence between wall
posts and its comments. This research evaluated posts and comments mood of
Facebook profiles, analyzing their linguistic features, and a measure to assess
an excessive self-presentation was introduced. Two new experimental measures
were built, describing the emotional loading (positive and negative) of posts
and comments, and the mood correspondence between them was evaluated. The
profiles "empathy", the mood coherence between post and comments, was used to
investigate the relation between an excessive self-presentation and the
emotional coherence of a profile. Participants publish a higher average number
of posts with positive mood. To publish an emotional post corresponds to get
more likes, comments and receive a coherent mood of comments, confirming the
emotional contagion effect reported in literature. Finally, the more empathetic
profiles are characterized by an excessive self-presentation, having more
posts, and receiving more comments and likes. To publish emotional contents
appears to be functional to receive more comments and likes, fulfilling needs
of attention-seeking.Comment: Submitted to Complexit
'Armas propias’ y maquiavelismo militar: con algunas notas sobre el concepto de autor en la tratadística del siglo xv
The circulation of Machiavelli’s Art of War made a fundamental contribution to the development of sixteenth-century vernacular military cultures. This essay analyses some specific aspects of the story of its reception and, in particular, focuses on the requirement of “one’s own arms” promulgated by Machiavelli’s book. This article deliberately examines two texts, which are different in both ideology and chronology: one originated in the context of the wars of religion and the diaspora of the French Protestants in the Swiss area, the other one dates back to the first half of the century. In fact, these works bring to light some of the most controversial aspects of the reception of the Florentine’s military thought. Further, they expose the difficulties that arise from applying a modern concept of authorship to texts born in a context which was characterized by a continuous recycling and reworking of themes and features, which had evolved within a long tradition of military writing and which, however, have been transformed, if not revolutionized by Machiavelli.La circulación de El arte de la guerra de Maquiavelo ha supuesto una contribución fundamental al desarrollo en lengua vernácula de la cultura militar europea del siglo xv. Este artículo analiza algunos aspectos específicos de la recepción de esta obra en la producción escrita militar de su tiempo, concentrándose en particular en aquellos elementos vinculados con la cuestión de las “armas propias” que tan ampliamente propagó este libro de Maquiavelo. Con este propósito, se ha escogido deliberadamente el ejemplo de dos obras diversas tanto en naturaleza ideológica como en su altura cronológica: la primera data de la primera mitad del siglo xv, la otra se originó en el contexto de las guerras de religión y de la diáspora de los protestantes franceses hacia suelo helvético. Se trata, en efecto, de dos libros que permiten comprender matices poco conocidos del proceso de reutilización de ciertos conceptos maquiavelianos que en su momento podrían ser considerados políticamente controvertidos. Al mismo tiempo, ambas obras son capaces de señalar o enfatizar la dificultad que emerge cada vez que se trata de aplicar el concepto moderno de autor a textos nacidos en un contexto caracterizado por un continuo reciclaje y reelaboración de temas y elementos adscribibles a una larga y articulada tradición de escritura militar desarrollada a lo largo del siglo, y que, sin embargo, había vivido un proceso crucial de transición con la contribución de Maquiavelo
Una possibile fonte delle Istorie fiorentine
Fondandosi sullo studio delle recenti acquisizioni documentarie concernenti una delle filze originali in cui erano riunite le carte appartenute a Niccolò Machiavelli, questo articolo avanza l’ipotesi di lavoro che la Cronica domestica di Donato Velluti potesse essere utilizzata dal Segretario fiorentino per servirsene nella redazione di alcuni capitoli delle sue Istorie fiorentine. Questa possibilità è sostenuta nel saggio sia da una comparazione testuale diretta tra alcune sezioni della fine del secondo e dell’inizio del terzo libro delle Istorie e l’opera di messer Donato, sia dall’esame di vari indizi biografici ed elementi di interpretazione
Evaluation of Structural and Temporal Properties of Ego Networks for Data Availability in DOSNs
The large diffusion of Online Social Networks (OSNs) has influenced the way people interact with each other. OSNs present several drawbacks, one of the most important is the problem of privacy disclosures. Distributed Online Social Networks (DOSNs) have been proposed as a valid alternative solution to solve this problem. DOSNs are Online Social Networks implemented on a distributed platform, such as a P2P system or a mobile network. However, the decentralization of the control presents several challenges, one of the main ones is guaranteeing data availability without relying on a central server. To this aim, users’ data allocation strategies have to be defined and this requires the knowledge of both structural and temporal characteristics of ego networks which is a difficult task due to the lack of real datasets limiting the research in this field. The goal of this paper is the study of the behaviour of users in a real social network in order to define proper strategies to allocate the users’ data on the DOSN nodes. In particular, we present an analysis of the temporal affinity and the structure of communities and their evolution over the time by using a real Facebook dataset
New provisions for the labelling of fishery and aquaculture products: Difficulties in the implementation of Regulation (EU) n. 1379/2013
The European Union (EU), within the renewal plan of the Common Fisheries Policy and the Common
Market Organization, with the Cape IV of Reg. (EU) n. 1379/2013 have introduced new requirements for
the labelling of fisheries and aquaculture products. These, as well as providing consumers with more
complete information, integrate the provisions of Reg. (EU) n. 1169/2011 and acts as a tool to prevent
frauds and illegal fishing. In this work the new seafood labelling provisions were evaluated, starting from
the analysis of the art. 35 of the Chapter IV and comparing it with the previous EU dispositions (Reg. (EC)
no. 104/2000 and no. 2065/2001). The exclusion of prepared and processed products and aquatic invertebrates
from the application of the mandatory seafood labelling provisions and the role of the mass
caterer operators with respect to the labelling requirements were identified as the two major shortcomings
that still need to be better addressed by the legislator. Overall, what emerged from this work is
that, if on the one hand the European legislation on seafood labelling has achieved important goals,
evolving and improving itself, on the other it is still controversial and plagued by the same problems as
15 years ago. Therefore, the authors suggest that the regulation is modified at least extending its scope to
all products and to at all stages of the fishery logistic chai
Steering efficiency of a ultrarelativistic proton beam in a thin bent crystal
Crystals with small thickness along the beam exhibit top performance for
steering particle beams through planar channeling. For such crystals, the
effect of nuclear dechanneling plays an important role because it affects their
efficiency. We addressed the problem through experimental work carried out with
400 GeV/c protons at fixed-target facilities of CERN-SPS. The dependence of
efficiency vs. curvature radius has been investigated and compared favourably
to the results of modeling. A realistic estimate of the performance of a
crystal designed for LHC energy including nuclear dechanneling has been
achieved.Comment: 16 pages, 6 figure
