Termini di pagamento e interessi moratori nei contratti di cessione nella filiera agroalimentare. Riflessioni sul d.lgs. 198/2021

2022

The paper focuses on the regulation of payment terms introduced by legislative decree n. 198/2021 that implement in the Italian legal system the directive 2019/633 on unfair trading practices in the agricutural and food supply chain. The paper try to link the new regulation to the principles of the law of obligations to resolve the issue relating to the payment term applicable in the absence of provisions by the parties; then the paper try to determine the default interest rate given the lack of clarity of the regulation on this point. The paper claims that the guarantee of certain payment terms does not solve the economic and financial problems of suppliers of agricultural and food product…

STRATEGY TO INCREASE THE FARM COMPETITIVENESS

2014

Italy’s wine-growing production structure is highly pulverized. So, for many wine-growing farms loweri ng the production cost represents the only way of gain ing a competitive advantage. Production at average unit costs lower than competitors allows to improve prof itability. Among farming operations, winter pruning and tying of productive vine-branches require a high hu man labor. For this reason the paper presents the r esults of research conducted on a sample of Sicilian wine- producing farms in order to study the cost-effectiv eness to make the pruning and the subsequent ligation of productive branches with tools that facilitate the work. The economic analysis, after the determination o…

How Universal Is the Relationship between Remotely Sensed Vegetation Indices and Crop Leaf Area Index? A Global Assessment

2016

This study aims to assess the relationship between Leaf Area Index (LAI) and remotely sensed Vegetation Indices (VIs) for major crops, based on a globally explicit dataset of in situ LAI measurements over a significant set of locations. We used a total of 1394 LAI measurements from 29 sites spanning 4 continents and covering 15 crop types with corresponding Landsat satellite images. Best-fit functions for the LAI-VI relationships were generated and assessed in terms of crop type, vegetation index, level of radiometric/atmospheric processing, method of LAI measurement, as well as the time difference between LAI measurements and satellite overpass. These global LAI-VI relationships were evalu…

Aldo Visalberghi and the italian School System in the Post-War Period

2021

The contribution aims to propose a reflection on the italian pedagogist and academic Aldo Visalberghi (1919-2007) who, influenced by the pedagogical theories of John Dewey (1859-1952), has critically analyzed the italian school of the immediate post-war period, which he himself called extremely authoritarian and, for this reason, demanding to live a change that transformed and improved the quality of teaching and learning of young italians. Through a critical reading of some bibliographical sources such as Scuola aperta published in 1960 and Insegnare ed apprendere. Un approccio evolutivo of 1988, it will be highlighted how Visalberghi offered to educators and teachers of his time suggestio…

The role of the Nature of Science in citizens' education

2007

O presente trabalho tem como propósito dar uma nova contribuição para o debate que se vem desenvolvendo, já faz algum tempo, em volta do papel da natureza da ciência na educação científica e, em particular, na formação de uma cidadania para a participação na tomada de decisões. This paper aims to contribute to the debate on the role of the nature of science and technology in science education, paying particular attention to preparing citizens to participate in decision making.

Assessment of mechanisms driving non-linear dose-response relationships in genotoxicity testing.

2014

In genetic toxicology, risk assessment has traditionally adopted linear dose-responses for any compound that causes genotoxic effects. Increasing evidence of non-linear dose-responses, however, suggests potential cellular tolerance to low levels of many genotoxicants with diverse modes of action. Such putative non-linear dose-responses need to be substantiated by strong mechanistic data that identifies the mechanisms responsible for the tolerance to low doses. This can be achieved by experimental demonstration of cytoprotective mechanisms and by providing experimental support for the existence of tolerance mechanisms against low dose effects. By highlighting key experiments into low dose me…

Structure-Function Relationship of Substituted Bromomethylcoumarins in Nucleoside Specificity of RNA Alkylation

2013

Selective alkylation of RNA nucleotides is an important field of RNA biochemistry, e.g. in applications of fluorescent labeling or in structural probing experiments, yet detailed structure-function studies of labeling agents are rare. Here, bromomethylcoumarins as reactive compounds for fluorescent labeling of RNA are developed as an attractive scaffold on which electronic properties can be modulated by varying the substituents. Six different 4-bromomethyl-coumarins of various substitution patterns were tested for nucleotide specificity of RNA alkylation using tRNA from Escherichia coli as substrate. Using semi-quantitative LC-MS/MS analysis, reactions at mildly acidic and slightly alkaline…

Allergic Rhinitis and its Impact on Asthma (ARIA) Phase 4 (2018): Change management in allergic rhinitis and asthma multimorbidity using mobile techn…

2019

Allergic Rhinitis and its Impact on Asthma (ARIA) has evolved from a guideline by using the best approach to integrated care pathways using mobile technology in patients with allergic rhinitis (AR) and asthma multimorbidity. The proposed next phase of ARIA is change management, with the aim of providing an active and healthy life to patients with rhinitis and to those with asthma multimorbidity across the lifecycle irrespective of their sex or socioeconomic status to reduce health and social inequities incurred by the disease. ARIA has followed the 8-step model of Kotter to assess and implement the effect of rhinitis on asthma multimorbidity and to propose multimorbid guidelines. A second c…
