Errore sulla paternità dell'opera d'arte: un'indagine di diritto comparato
No full textSono sempre più frequenti i casi di inconsapevoli acquirenti che scoprono di essere entrati in possesso di un’opera d’arte di grande valore.
Ciò accade all’uomo comune ma talvolta coinvolge anche professionisti del settore.
Con il presente lavoro monografico, l’autore ricostruisce i profili giuridici di questa tipologia di transazioni nel mondo dell’arte, analizzando come tali coincidenze siano state affrontate, catalogate e risolte nel solco delle diverse famiglie giuridiche della Western Legal Tradition
ANIMALS IN GAMES AND BETS : HORSERACING IN THE USA
No full textThe favor towards the sport activities has long allowed a wide
range of sport competition where animals have been employed. Wagers on
competitions with animals have always existed and the first being authorized
by the legal systems.
Among these kinds of bets, horseracing constitutes the cornerstone of the
topic and so, after a short history, the US legal system will be examined for its
role of somewhat of trailblazer.
The legal developments surrounding this complex and highly regulated
sport have reflected ceaseless transformations.
In the twenty-first century, thoroughbred racing is a sophisticated, highly
regulated, often lucrative, and frequently controversial sport that draws the
attention of a wide range of interested parties. Along with wagering and
taxation, Horseracing has recently been under public examination concerning
the health and safety both of the horses and the jockeys.
Notwithstanding these issues, the races are still taking place with poor
attention for the living beings involved
Advanced microfluidic strategies for core-shell nanoparticles: the next-generation of polymeric and lipid-based drug nanocarriers
Full text linkMicrofluidic technology has transformed the synthesis of core-shell nanoparticles (CSNPs), providing an unprecedented level of control over their structural and functional properties. This review critically evaluates recent advancements, highlighting the superiority of microfluidic methods over conventional batch techniques, which often suffer from variability and scalability issues. Indeed microfluidic platforms enable the precise manipulation of reaction conditions, leading to highly uniform nanoparticles with optimized characteristics. This level of precision is particularly relevant in drug delivery, where the ability to fine-tune nanoparticle size, composition, and surface properties directly influences therapeutic efficacy. A fundamental aspect of this approach lies in the choice of synthesis techniques, such as nanoprecipitation and emulsification, which leverage the confined microscale environment to promote controlled self-assembly. Equally important is the selection of materials for microfluidic chip fabrication, as properties such as chemical resistance, biocompatibility, and manufacturability determine the feasibility of large-scale production. The integration of microfluidics into nanoparticle production is not merely a technical refinement but a step toward a more efficient and adaptable nanomedicine. By integrating these strategies, microfluidics emerges as a key enabler for the clinical translation of nanomedicine. To bridge the gap between lab-scale synthesis and industrial production, this review discusses high-throughput microfluidic platforms and multilayered designs
Daily and circadian rhythms of rest and activity of Talpa romana Thomas (Mammalia, Insectivora: Talpidae). Preliminary results
No full textDaily and circadian rhythms of rest and activity were investigated on six adult moles
(Talpa romana). Preliminary results from a seven months study are presented. Animals were housed in separate cages and their activity monitored by means of automatic recording. Two sessions of automatic recording were run in different captive conditions and photoperiod regimes (natural light/dark conditions and constant dark). As a general rule, all activities showed a link with photoperiod under LD conditions. All animals displayed a clear diurnality in spite of strong interindividual differences in their activity pattern. In constant dark, two moles out of three showed a marked loss of organization in their activity pattern and absence of a clear circadian rhythmicity. Despite the absence of exposition to the natural LD cycle in subterranean environment, preliminary results suggest that light is likely to maintain a role in the regulation
of activity patterns also in this fossorial species
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
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
