Peer to Consumer Lending
No full textPeer to consumer lending represents an alternative form of financing characterized, within
the crowdfunding genus, by the collecting of credit offers to be matched with borrowing demand through a digital platform. The essay focuses on legal analysis of some aspects of the
structure and the functioning of lending marketplaces operating in the sector at stake. The
Author argues how this business model – especially when the phenomenon involves consumers and, more generally, non-professionals counterparts – may be critical as regards to the
classical cathegories and concepts ruling the lending/borrowing discourse
La proposta di regolamento MiCA e la disciplina delle pratiche commerciali scorrette
No full textThe most part of European and domestic supervisory authorities have underlined the likelihood
that either the issuing and the negotiation of cryptoassets may be the final outcome of
unfair and deceptive commercial practices. The discipline laid down by the Directive 2005/29/
CE – now expressely recalled by the MiCAR Proposal – seems to be crucial for the best functioning
of the market at stake. The Author stresses how the interplay between «horizontal»
and «vertical» measures needs the interpreters play a pivotal role, in order to grant the best
understanding of the circumstances of the case as well as the best using of the «professional
diligence» general clause
Use of stable isotopes (delta13C and delta15N) for detecting the dispersione effect of fish farming waste: a stydu case from southern Tyrrhenian Sea (MED)
No full textThe effect of mariculture facilities on water column trophodynamics as revealed by biochemical features of suspended organic matter (South Tyrrhenian, MED).
No full textA comparison of a Mediterranean aquaculture impacted area and control areas was made to assess the effect of fish farm waste discharge on
the biochemical features of the water column. Trophic variables commonly used in marine ecology such as total suspended matter, suspended
chlorophyll-a, biochemical features of particulate organic matter (proteins, lipids and carbohydrates) and biopolymeric carbon were chosen as
the best descriptors of trophic conditions. An initial analysis of data from the impact area was carried out in order to test the effect of farm waste
using a gradient of distances downstream from the fish farm cages (50 m, 300 m, 1000 m). The results were then compared with a control site
750 m upstream. Subsequently, the cage data set was asymmetrically compared with data from five controls collected some years before, when
no aquaculture activity was present in the Gulf. The analysis revealed differences in chlorophyll-a, carbohydrates and some trophic ratios between
the farm impact area and the controls taken upstream. A clear pattern of trophic enrichment of the water column around the fish farm was
evidenced since concentrations in the sites increased along with their distance from the cages. The downstream sites overall were significantly
different, trophically speaking, from the five control areas, while the trophic variables of the upstream control were not different from the external
controls. Results showed that fish farm facilities provided an organic enrichment of the water column up to at least 1000 m downstream
from the cages, producing a deviation of trophodynamics from normal ambient conditions
Effect of fish farming wastes on sedimentary and particulate organic matter origin in a Southern Mediterranean area (Gulf of Castellammare, Sicily): a multiple stable isotope study (delta13C and delta15N)
No full textCarbon and nitrogen stable isotope analysis was used to investigate the dispersion area of waste
material coming from fish farming activities in the western Mediterranean. Tests were conducted to see if uneaten feed and faecal material isotopic signals, originating from fish farms, could be detected in particulate organic matter (POM) and sedimentary organic matter (SOM). The detectable dispersion distance (from under cages as far as 1000 m) of cage-derived organic material was also examined. To do this, carbon (d13C) and nitrogen (d15N) composition in POM and SOM collected around the cages, in some control areas and in the waste material, was measured. Mean POM d13C was delta22.9F0.2x, while SOM d13C was 22.1F0.1x, and did not show significant differences along a distance gradient. Mean POM d15N was 3.9F1.0x, while SOM d15N was 3.4F1.3x, showing significant differences between 15N-enriched sites positioned near the cages and 15N-depleted sites positioned at about 1000 m from the cages. The mixing model applied to each reservoir (POM and SOM) as targets showed an incidence of autochthonous carbon (mostly phytoplankton in the particulate and sand microflora in the sediments) of about 24% in POM and of about 19% in SOM. Terrigenous carbon, which represented 37% in POM and 33% in SOM, increased in moving from sites nearby cages to more distant sites. Farming waste carbon represented 39% in POM and 48% in SOM. The inputs of autochthonous N represented about 24% in POM and about 18% in SOM, and with terrigenous N (representing 62% and 70%, respectively, in POM and SOM) showed higher contribution than cage-derived nitrogen. On average, farming waste nitrogen in POM was 15%, while it was 11% in SOM. d15NPOM showed a significant difference between cage sites and sites positioned at about 300 m. The latter was similar to sites located at 1000 m from the cages. Results indicate that in a Mediterranean oligotrophic area, with a bottom about 25 m deep and a mean current speed of 10–12 cm s 1, the influence of carbon and nitrogen from farming waste can be isotopically detected both in the particulate matter and the sediments in a wide area around fish farming cages. Sediments around the cages have been observed to be organic-enriched at about 1,000 m from cages. Dispersion of cage waste by hydrodynamic advection, consumption and defecation by wild fish, and resuspension from the bottom currents were invoked as three combined factors to explain the greater impact area found in this study than has been previously reported in the literature
Use of stable isotopes (δ13C and δ15N) for detecting the dispersion effect of fish farming waste: a study case from southern Tyrrhenian Sea (MED)
No full textDisciplina generale delle obbligazioni e sovraindebitamento
No full textThe essay compares the law of obligations and the
law of over-indebtedness with the aim of examining whether and to what extent
they interact. To this end, the Author highlights the diversity of assumptions and
effects -which is first and foremost a diversity of perspective-between them and
then clarifies their relationship in terms of alternativity and self-sufficiency. On
these premises, it is argued that despite the reported differences, the over-indebtedness rules are capable of changing the face of the obligation in more than
one respect. In particular, the possibility of a fresh start offered to “any debtor”
undermines the idea of an essentially enforceable bond and marks the demise
of the Civil Code obligation as the prototype of market relations
The exploitation of quartzite in Layer 5 (Mousterian) of Scladina cave (Wallonia, Belgium): flexibility and dynamics of concepts of debitage in the Middle Palaeolithic
No full textInternational audienceThis study concerns the management of the quartzite pebbles collected close to the site. Approximately fifty refits in a single series permit the reconstruction of the morphology of the core and the description of the technological treatment applied to it. The most complete refit series shows the coexistence of several methods of debitage on this raw material alone; but, also, their succession in the same block. The series provides evidence of a flexibility of concepts of debitage and evidence of dynamic relations between these concepts. Quartzite is the object of special treatment according to several criteria: economic, since flint is not available in the local environment of the cave; morphometric, the production is conditioned by the precise choice in the selection of the blocks; petrology, the nature of the material does not allow the knapper the same important liberty in knapping as flint permits. Este estudo diz respeito à gestão de seixos de quartzito recolhidos na proximidade do sítio arqueológico. Cerca de 50 remontagens permitem reconstruir a morfologia dos blocos originais, bem como descrever o seu tratamento tecnológico. As remontagens mais completas testemunham a coexistência de vários métodos de debitagem aplicados a esta matéria – prima, mas também a sua sequência na exploração do mesmo bloco. Esta série evidencia a flexibilidade dos conceitos de debitagem e as suas relações dinâmicas, sendo o quartzito explorado especificamente de acordo com vários critérios: económicos, uma vez que o sílex não se encontra na proximidade da gruta; morfométricos, já que a produção é condicionada por uma escolha precisa do bloco; petrográficos, porque esta matéria-prima apresenta mais constrangimentos do que o sílex.Cette étude concerne la gestion des galets de quartzite récoltés à proximité du site. Une cinquantaine de remontages permettent de reconstituer la morphologie des blocs de départ et de décrypter le traitement technologique qui leur fut appliqué. Les remontages les plus complets témoignent de la coexistence de plusieurs méthodes de débitage sur cette matière première, mais aussi de leur succession au sein d'un même bloc. La série met donc particulièrement en évidence la flexibilité des concepts de débitage et les relations dynamiques qu'ils entretiennent. Le quartzite est traité spécifiquement selon plusieurs critères. Economiques, puisque le silex est absent à proximité de la grotte; Morphométriques, la production étant conditionnée par des choix précis dans la sélection des bloc; Pétrologiques, le matériau étant plus contraignant que le silex
Technical and Economic Efficiency of Vine Pruning: Results of Experimental Trials of Some Cultivars of Grapevine Grown in Sicily and Determination of Break-even Point
No full textThe research presents the results carried out on Sicilian viticulture in order to study the economic
sustainability of the agricultural company. In particular, the author examined the operation of dry pruning and tying
of the fruiting head in espalier vineyards with tools that facilitate the work. The economic analysis highlights that
equipping yourself with mechanical tools that facilitate work is convenient for both large and small wineries. The results
of the research highlight that the investment to facilitate pruning and tying in Guyot-trained vineyards can also be made
by wine-growing companies and is increasingly convenient as the area under vines involved increases
