Bergamo, Leningrado-San Pietroburgo. Giacomo Quarenghi 1967-2017
No full textQuesto contributo al catalogo del fondo dei disegni di Giacomo Quarenghi (1744-1817), conservati presso l’Accademia Carrara di Bergamo, e fino ad ora mai completamente studiati, mette a fuoco eventi, pubblicazioni e ricorrenze quarenghiane dal primo centenario della nascita dell’architetto bergamasco ad oggi. Il contributo intende proporre un quadro storico dell’attività di ricerca dedicata a Giacomo Quarenghi, grazie alla quale si assistette, nel 1967, all’inizio della collaborazione tra ricercatori russi e italiani che, fino a quel periodo, si erano occupati dell’autore e della sua opera in modo autonomo. Questa collaborazione scientifica ha costruito una significativa sintonia e un rapporto proficuo tra Russia e Italia, dal quale sono scaturiti importanti contributi allo studio dell’architetto bergamasco e della cultura architettonica legata al suo tempo.The contribution to the catalogue provided by the collection of drawings by Giacomo Quarenghi (1744-1817), preserved at the Carrara Academy in Bergamo and until now never fully studied, focuses on events, publications and Quarenghi’s anniversaries, starting from the first centenary of the birth of Bergamo’s architect to date. The contribution intends to propose a historical picture of the research activity dedicated to Giacomo Quarenghi, thanks to which we witnessed, in 1967, the beginning of a collaboration between Russian and Italian researchers who, until then, had worked independently on the author and his work. This scientific collaboration has seen the beginning of a harmonious and a fruitful relationship between Russia and Italy, from which important contributions to the study of Bergamo’s architect and the architectural culture linked to his time have originated
Combined Approach To Remove and Fast Detect Heavy Metals in Water Based on PES–TiO2 Electrospun Mats and Porphyrin Chemosensors
No full textHybrid poly(ether sulfones) (PES)-TiO2 electrospun mats are used as selective filters to remove lead and zinc ions from water. Presence of TiO2 is functional to trigger fiber's surface charge that allows for better performances in terms of ionic adsorption with respect to bare PES mats. Temperature increase promotes a speed up of ion removal. Ability of electrospun mats to retain adsorbed ions is proven by washing procedures, which confirm the lack of released Pb2+ in solution, even after sonication. To detect presence of metal ions in aqueous solutions, water-soluble porphyrins are used as chemosensors, which are able to provide fast, in-field, and real-time analysis. In particular, cationic H2T4 metalation, occurring both in solution or at transparent glass surface, allows for a straightforward spectrophotometric (UV-vis) detection of metal ions in solution
Che cos'è un libro?
No full textA new annotated Italian traslation, by Maria Chiara Pievatolo, of I. Kant, Metaphysik der Sitten, Rechtslehre, § 31, II. Its goal is showing that Kant by "persönliches Recht" did not mean a fundamental right of the person, but simply a right concerning relations among persons. It is sufficient to see Kant's definition of "persönliches Recht" in MdS §18 to realize it.
For this reason, it is a mistake to assert that Kant endorsed intellectual property as a basic human right. From his point of view, the right to publish a book depended only on a personal contract between the author and the publisher
Metajournals. A federalist proposal for scholarly communication and data aggregation
No full textWhile the EU is building an open access infrastructure of archives (e.g. OpenAIRE) and it is trying to implement it in the Horizon 2020 program, the gap between the tools and the human beings – researchers, citizen scientists, students, ordinary people – is still wide. The necessity to dictate open access publishing as a mandate for the EU funded research – ten years after the BOAI - is an obvious symptom of it: there is a chasm between the net and the public use of reason. To escalate the advancement and the reuse of research, we should federate the multitude of already existing open access journals in federal open overlay journals that receive their contents from the member journals and boost it with their aggregation power and their semantic web tools. The article contains both the theoretical basis and the guidelines for a project whose goals are: 1. making open access journals visible, highly cited and powerful, by federating them into wide disciplinary overlay journals; 2. avoiding the traps of the “authors pay” open access business model, by exploiting one of the virtue of federalism: the federate journals can remain little and affordable, if they gain visibility from the power of the federal overlay journal aggregating them; 3. enriching the overlay journals both through semantic annotation tools and by means of open platforms dedicated to host ex post peer review and experts comments; 4. making the selection and evaluation processes and their resulting data as much as possible public and open, to avoid the pitfalls (e. g, the serials price crisis) experienced by the closed access publishing model. It is about time to free academic publishing from its expensive walled gardens and to put to test the tools that can help us to transform it in one open forest, with one hundred flowers – and one hundred trailblazers

The article aims to offer the reader a revised text of this Latin fragmentary poem, based on the direct examination of the papyrus. A commentary and a discussion about the author are provided
The scope of property: why does Kant reject the concept of intellectual property?
No full textAlthough both Fichte and Kant are often included among the intellectual property forerunners, there are at least three outstanding differences between the former and the latter: 1. Fichte bases copyright on the individual originality in the form of expression; Kant does not mention originality at all; 2. Fichte equates copyright with private property; Kant rejects the very possibility of founding the authors' right on a ius reale; 3. Fichte believes that copyright violators deserve the same harsh punishment of thieves. According to Kant, the unauthorized printer should simply compensate all the damages he caused to the author or to his authorized publisher. While Fichte is an intellectual property endorser, Kant is an “enlightened” conservative who supports the Roman law tradition, according to which property applies only to material, touchable things (res quae tangi possunt). He accepts the copyright principle, according to which authors are entitled to decide how to publish their works, but describes it as rights concerning only the relationships among persons. The rights of the publishers, besides, are justified only as long as they help authors to reach the public. Kant's copyright is not property; it has the function to protect authors' freedom to share their texts as they prefer, and to make it easier to communicate them to the public. And, if it has to be seen as a means to foster the publication and the diffusion of texts, its rules should also depend on the prevailing media technology. Kant maintained almost the same copyright theory both in his 1785 essay Von der Unrechtmäßigkeit des Büchernachdrucks and in the Metaphysik der Sitten (1797). In 1797, however, Kant bases property on a possessio noumenon that is different, as a juridical, rational possession, from the physical possession. Why does Kant reject the very concept of an intellectual property while advocating an intellectual theory of property? Answering to such a question could help us the provide a general understanding of the functions and the limits of property in Kant's thought
Performance Management Systems: Design, Diagnosis and Use
No full textThis book presents an analysis and a critical discussion on performance management systems. It seeks to advance the current state of knowledge in the subject by introducing a holistic performance management system - the loosely coupled performance management system. This new system presents a framework to leverage the systemic relationships among already established performance management mechanisms. The author contends that loosely coupled performance management systems fulfill two different objectives, namely - they assure control and foster innovation. Such a comprehensive approach to management control provides managers of economic organizations with an overarching architecture for the design, diagnosis and effective use of performance management systems.
Rapidly fatal West Nile virus meningoencephalitis in an immunocompetent patient: a case report
No full textAbstract
Background
West Nile virus (WNV) is a Flaviviridae most often transmitted by mosquitos. Clinical manifestations vary from no symptoms to neuroinvasive disease. Mortality is rare, but patients with neuroinvasive disease have a fatality rate of 4-14%. Diagnosis is made on epidemiological, clinical and serological criteria. Treatment is based on symptomatic and support therapy. WNV neuroinvasive disease seems associated to advancing age and diabetes, but poor prognosis risk factors are still not clearly recognized.
During 2017-2018 10 patients affected by WNV infection were admitted to our Hospital (Policlinico of Modena): 3 patients had a rapid fatal outcome and 3 needed intensive care transfer. We report the most representative case.
Case Report
A 81-yr-old man from Emilia-Romagna was admitted to our unit with a 6 days history of fever (>38°C), fatigue, nausea, vomiting, hiccough and mild cognitive impairment treated with amoxicillin. Past medical history: type 2 diabetes mellitus, arterial hypertension, permanent pacemaker for type 3 atrioventricular block. Referred exposure to farm animals. No recent travels abroad. Chest x-ray showed a retrocardiac opacity, so empiric levofloxacin was started for suspected community acquired pneumonia. After two days the patient began lethargic with a Glasgow Come Score < 8. Neuroinvasive WNV disease was confirmed by electroencephalogram and rachicentesis. Before serologic results acyclovir and dexamethasone were initiated without benefit and patient diedon the fifth day after admission.
Conclusions
Risk factors for poor prognosis related to WNV Infection are still not clearly identified. Our patient underwent unexpected rapid clinical deterioration before invasive treatment could positively affect prognosis. This underlines the importance of clinical alert to WNV infections during transmission season in endemic areas and the necessity of more data on fatal WNV cases to define criteria to promptly recognize high-risk patients.

Pour un réalisme acoustique : Un de Baumugnes de Jean Giono
No full textUn de Baumugnes by Jean Giono (1929) is the second volume of the “Pan trilogy”. This novel presents and even defends a “realistic” poetics in line with the research of other French and francophone writers in the 1920s and the 1930s. Both the construction of the text and its practice of language are consistent with the critical discourses that the author disseminates during the same period: all of them contribute to set up an “acoustic realism” which is the great novelty of the interwar period. Finally, this article proposes a reading of the central scene of the novel by taking into account Roland Barthes’ theories on the “reality effect”: the music (which is the object of the novel) and the musicality of the literary language that evokes it, marked by features of orality, make it possible to recall reality through “the direct collusion of a referent and a signifier”.Un de Baumugnes de Jean Giono (1929), deuxième volume de la « trilogie de Pan », est un roman qui présente et qui défend même une poétique « réaliste » en phase avec les recherches que mènent, à la même époque, d’autres écrivains de langue française. La construction du texte et la pratique de la langue qu’il déploie sont cohérentes avec les discours critiques que l’auteur dissémine au cours de la même époque : les unes et les autres vont dans la direction d’un « réalisme acoustique » qui se configure comme la grande nouveauté des années 1920 et 1930. Pour finir, cet article propose de lire la scène centrale du roman à la lumière des théories de Roland Barthes sur l’« effet de réel » : la musique (dont il est question dans le texte) et la musicalité de la langue littéraire qui l’évoque, marquée par des traits d’oralité, permettraient d’évoquer le réel par « la collusion directe d’un référent et d’un signifiant »
