I diritti umanitari non hanno confini
No full textIn molte occasioni, operatori professionali di diversa estrazione, ma soprattutto di area sanitaria, sono chiamati a svolgere missioni internazionali umanitarie. Nell’ambito di tali interventi si pone non di rado una questione molto particolare, ma per nulla secondaria: allorché uomini e mezzi appartenenti ad una nazione, si trovino a compiere operazioni, specie in situazioni di emergenza, in un’altra nazione, fuori territorio appunto, entro quale raggio d’azione possono muoversi, senza incorrere in responsabilità? Quali sono gli obblighi che essi debbono rispettare? E in particolare: sono soggetti alle leggi locali? Sono soggetti alle leggi del Paese a cui appartengono? O ad entrambe? Il problema si è posto in diverse occasioni, ed è stato sollevato soprattutto dal personale impegnato nei programmi alimentari: quali regole di igiene vanno applicate e rispettate? E’ evidente che un’applicazione delle norme europee sull’igiene delle produzioni zootecniche (ad esempio), o sulla qualità e conservazione degli alimenti, rischierebbe di provocare la paralisi di molti di quei programmi. D’altra parte, il rischio di incorrere in responsabilità per la mancata applicazione delle norme è avvertito come incombente.

INTEGRATED THERMAL ENERGY STORAGE SYSTEM - ROLE OF MANAGEMENT STRATEGY IN DESIGN OF A STORAGE TANK
No full textIn recent years, our society has experienced an important energy transition that is becoming a central aspect in geopolitical choices in several countries around the world. However, several issues arise from these scenarios, in which an increasing number of RES power plants are installed and connected to electrical grids. In fact, most renewable sources, such as wind and solar, are characterised by a fluctuating and unpredictable behaviour that causes a decrease in the quality of the energy transmitted through the grid and leads to a more difficult management of the grid itself. To mitigate and reduce these negative aspects, it is important to install devices, such as storage systems, capable of facilitating the correct management of electrical grids, meeting, at the same time, the electrical demand of the users and the energy produced in RES-based power plants. Although several technologies have been proposed over the years, Carnot batteries seem to guarantee adequate performances without stringent geographical constraints and represent a promising solution. Among them, integrated thermal energy storage systems (IT-ESS) can be easily installed and coupled with existing power plants. The central element of such technology is represented by a sensible heat-thermal energy storage device, consisting of a packed bed. The literature is still lacking accurate design methods for the storage tank, and this is the leading aspect that led the authors to develop an innovative procedure to determine the size of the storage device, based on the necessity of producing energy during the night, while the accumulation phase occurs during the day. In this phase, the power of a photovoltaic plant is exploited: the plant is described through curves that reproduce the power generated in a typical day for each month of the year. An algorithm built in the MATLAB environment had been used to determine the volume of the storage device, with the goal of being able to cover the hours in which the PV is not producing energy. The results of the analysis have underlined the need to consider in a proper way both the user needs and the characteristics of the renewable power plants, to correctly evaluate the volume of the storage tank to be installed in the system
Denuncia delle malattie infettive del bovino in ambito comunitario
No full textCom’è noto, tra il diritto nazionale (altrimenti detto diritto “interno”) e quello comunitario esiste un rapporto di integrazione (e non di coordinamento, come invece avviene tra il diritto interno e quello internazionale) per cui il primo, per potersi completamente realizzare, deve integrarsi nel secondo. Per converso, il legislatore nazionale è chiamato ad una continua opera di aggiornamento e revisione delle norme interne, per adeguarle e renderle congruenti a quelle comunitarie dal momento che, in special modo nei settori dell’agricoltura, sicurezza alimentare e salute pubblica, i due ordinamenti sono rivolti necessariamente ai medesimi destinatari (comunità di soggetti) essendo queste materie comunitarizzate nell’ambito del c.d. “primo pilastro” dell’Unione Europea.
Senza entrare nell’analisi della natura di tale rapporto d’integrazione, né di come venga risolto il conflitto eventuale che tra essi può istaurarsi, è però necessario evidenziare che, in queste materie, non sempre risulta agevole identificare il diritto vigente. Ciò è di particolare interesse ed impatto nel settore veterinario e zootecnico, non solo a causa del ritardo che talora si registra nell’adeguamento del diritto nazionale nella fase di recepimento di atti quali le Direttive e le Decisioni, ma anche per il sempre maggior ricorso del legislatore comunitario ad atti direttamente applicabili quali i Regolamenti o, in taluni casi, le c.d. “Direttive dettagliate”.
Da tali sintetiche considerazioni ne è derivata l’ipotesi principale del presente lavoro: analizzare quale sia il livello di adattamento dell’ordinamento italiano al corpus juris comunitario in materia di misure di polizia sanitaria per la lotta alle malattie infettive degli animali. In particolare, il nostro obiettivo finale è stato quello di verificare se le malattie infettive degli animali da sottoporre a denuncia obbligatoria a norma dell’art. 1 del Regolamento di Polizia Veterinaria (D.P.R. 320/54) siano le stesse previste dalle norme comunitarie vigenti.
Per poter procedere a tale analisi, tuttavia, è utile fare due considerazioni preliminari: la prima relativa ai concetti di denuncia e di notifica di malattia infettiva, la seconda relativa alla metodologia più efficace per l’analisi sistematica del diritto comunitario vigente in materia
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

No full textCan archives of audiovisual TV interviews be used to make authors more visible to students, and thereby reduce the learning gap between native and non-native language speakers in college classes? We examined students in a college course who learned about one scholar's ideas through watching an audiovisual TV interview (i.e., visible author format) and about another scholar's ideas through reading a formal text description (i.e., invisible author format). For the invisible author, native language speakers scored significantly higher than the non-native language speakers on a corresponding exam question (i.e., a cognitive measure), generated more words on the exam question (i.e., a motivational measure), and mentioned the author's name more often in answering the exam question (i.e., an affective measure). For the visible author, the groups did not differ on any of these measures. These findings provide evidence for the idea that making the author visible through audiovisual TV interviews can eliminate the learning gap between native and non-native language speakers. 3 Universities around the world serve students who are non-native speakers of th
