Implications of Distributed Ledger Technologies on Firm Cost Structure and Supply Chain Integration
Full text linkTechnological infrastructures based on distributed ledger technologies (DLTs) like blockchain technology (BCT) are new digital technologies combining peer-to peer networking and cryptography to create immutable public ledgers characterized by decentralization, collective maintenance, consensus trust and reliable data. DLT, today considered as an interdisciplinary topic, is expected to transform current economic organization and governance, and can be considered one of the evolutionary next steps for agriculture, particularly for current state-of-the-art of precision agriculture
Documenting the archaeological landscape using low-cost equipment: 3D capturing, modelling and visualization of the site of Aptera (Crete) for the DIACHRONIC LANDSCAPES workshop
No full textThis study examines activities at the archaeological site of Aptera in Crete, Greece, as part of the Diachronic Landscapes 2023 International Design Workshop, organized by CAM (Center for Mediterranean Architecture), TUC (Technological University of Crete School of Architecture), and UNIFE (University of Ferrara Department of Architecture). The research focuses on low-cost aerial survey and Structure-from-Motion data processing. This approach enabled the creation of digital outputs like point clouds, DTM, DSM, orthophotos, and contour lines, essential for the analysis and design phases of the workshop. The digital models, demonstrating the site’s historical layers and current landscape, offered valuable insights for visualizing Aptera’s evolution and informed design decisions. This interdisciplinary endeavor highlights the synergy between modern technology and archaeological study, suggesting lowcost and effective possibilities for heritage conservation and landscape architecture
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Piacenzian–Gelasian non-marine ostracods from the Dunarobba Fossil Forest (Tiberino Basin, Umbria, central Italy)
No full textThe taxonomy of some non-marine ostracod assemblages from the Dunarobba Fossil Forest area (south Tiberino Basin, Umbria, Italy) is discussed, adding to the scientific understanding of Piacenzian–Gelasian non-marine ostracods in central Italy and providing a palaeoenvironmental reconstruction of the shallow coastal lacustrine environments of the Palaeolake Tiberino. The ostracod assemblages include Darwinula stevensoni, Vestalenula cylindrica, Candona (Candona) improvisa, Candona (Neglecandona) neglecta, Candona (Neglecandona) angulata, Candona (Neglecandona) paludinica, Caspiocypris basilicii, Caspiocypris tiberina, Candonopsis kingsleii, Cyclocypris ovum, Ilyocypris bradyi, Ilyocypris decipiens, Cypris mandelstami, Zonocypris membranae quadricella, Potamocypris fulva, Cyprideis crotonensis, Cyprideis rectangularis and two new species: Hemicypris lomastroi sp. nov. and Paralimnocythere turgida sp. nov. In addition to widespread European species, the ostracod assemblages contain some rare species that were previously known from the Pliocene Paludinian Beds of Serbia. A cluster analysis applied to the ostracod frequency matrix has lead to the identification of four separate assemblages that can be attributed to several ecological niches, including emerged hydrosols, ephemeral coastal pools and a littoral lacustrine margin, which suggest a complex coastal environment
Paesaggi digitali della memoria. Il Campo di Fossoli e il Museo Monumento al Deportato a Carpi
No full textRacchiuso nel paesaggio emiliano, a pochi chilometri dalla città di Carpi, Il Campo di Fossoli viene costruito durante il secondo conflitto mondiale come Campo per prigionieri di guerra e Campo di concentramento speciale per ebrei. La vicinanza al Campo di Fossoli, oggi Sito di memoria, porta alla realizzazione in Italia del primo Museo Monumento al Deportato politico e razziale a Carpi, inaugurato nel 1973 all’interno del Castello dei Pio, opera degli architetti milanesi BBPR. Da allora, il tipico paesaggio rurale emiliano che accoglie Fossoli dialoga con quello storico di Carpi tra un intrecciarsi di luoghi e memorie. Attraverso la scelta del Sito storico del Campo di Fossoli e il Museo Monumento al Deportato polito e razziale di Carpi, obiettivo di questo contributo è quello di fornire una nuova visione dei paesaggi della memoria analizzati, utilizzando alcuni tra i vari linguaggi digitali applicati al patrimonio architettonico. In particolare, si indagheranno le potenzialità offerte dai ‘gemelli digitali’ in grado di accrescersi attraverso l’archiviazione, l’aggiornamento, l’interpretazione e lo scambio di informazioni di diversa natura, perseguendo così le finalità dell’Heritage Building Modelling (HBIM), uno degli scopi di Inception, Spin-off dell’Università di Ferrara nel quale gli autori di questo articolo lavorano. In questa costruzione di paesaggi virtuali della memoria capaci di vedere il mondo reale nella sua ricchezza culturale – materiale e immateriale – il paper fornirà un punto di riflessione sulla possibilità del conservare, ma anche ‘fare memoria’ attraverso l’uso dei nuovi linguaggi digitali
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
