The contract’s progressive formation: amendments to offer, counteroffer and partial agreement’s regulation in the new argentine private law
No full textEl trabajo aborda la formación progresiva del contrato en relación con los casos en que el destinatario/aceptante introduce modificaciones a la oferta. Se inicia planteando esquemáticamente las diferentes hipótesis posibles y luego se repasan las soluciones del derecho comparado y el derecho global. A continuación, se analizan detalladamente las normas incorporadas en el nuevo Código Civil y Comercial, destacando las dificultades de interpretar conjunta y armónicamente lo dispuesto en los artículos 978 y 982 de dicho cuerpo normativo. Sobre el final, se ensaya un esquema general que contempla los diferentes casos que nacen a partir de la introducción de modificaciones a los términos originales de la oferta y se establecen los efectos de cada uno de ellos en el nuevo Derecho Privado argentino.This essay discusses the progressive formation of the contract in relation with the cases in which the accepting party makes amendments to the offer. The author begins by pointing out the different possible hypotheses in the light of Comparative Law and Global Law. Afterwards, he analyzes the new Civil and Commercial Code regulation, focusing on the difficulties that may arise out of making an overall interpretation of Sections 978 and 982 of such legal body. Finally, the author makes a general scheme that contemplates the different cases that may occur where changes are made to the original terms of the offer, and the effects derived from each case pursuant to the new Argentine Private Law.Fil: Valicenti, Ezequiel Andres.

The Cuticular Hydrocarbons of Dasineura Oleae Show Differences Between Sex, Adult Age and Mating Status
No full textAbstract: In insects, cuticular lipids prevent water loss and act as semiochemicals. Because of their ecological function, the profile change across the insects’ sex and development offers insight into insect biology and possible tools for pest management. Here, the first work on cecidomyiid cuticular extracts is proposed considering Dasineura oleae (Diptera: Cecidomyiidae) males and females at different adult ages (0–12 h, 12–24 h, 24–36 h) and distinct sexual conditions (virgin and mated). A set of 49 compounds were recorded (12 alkanes, 1 monomethyl alkane, 11 fatty acids, 4 esters, 1 aldehyde, 1 allylbenzene, 1 amine, 1 flavonoid, 1 ketone, 1 phenol, 1 steradiene, 1 sterol, 1 terpene, 1 triterpene and 11 unknown compounds), and 18 of them showed significant differences between groups. Among alkanes, hexacosane (nC26) exhibited a decreasing trend from the youngest to the oldest females, while pentacosane (nC25) and nonacosane (nC29) showed a decreasing trend from 0 to 12 h to 12–24 h virgin females. In addition, nonadecane (nC19) was significantly more abundant in the youngest males compared to older males and females. The alkanes nC25, nC26 and nC29 have been reported to be age-related also in other dipterans, while nC19 has been described as gender-specific chemical cue for platygastrid parasitoids. Further behavioural trials and analyses are required to assign the specific ecological roles to the characterized compounds. Our results may contribute to develop new low-impact control strategies relying on the manipulation of D. oleae’s chemical communication (e.g. disruption of mating or species recognition). Highlights: • Cuticular hydrocarbons are often involved in dipteran intraspecific communication. • We explored the cuticular profile of D. oleae at different age, sex, mating condition. • Five alkanes and one mono-methyl alkane showed differences among groups. • Linoleic acid is the most abundant compound in virgins, absent in mated insects. • Eleven compounds disappear in mated insects, but were present in all virgins.

Il piano di manutenzione come strumento per la domanda di servizio: il caso della gestione dei siti industriali
No full textIl saggio illustra un modello di gestione dei servizi di manutenzione programmata per edifici industriali e commerciali; su tale modello, messo a punto nel corso di una serie di esperienze realizzate nel corso degli ultimi anni – alcune delle quali documentate in queste pagine –, è stata elaborata e testata una procedura di appalto dei servizi di manutenzione alternativa a quella tipica dei contratti in Global Service ed estendibile anche a patrimoni immobiliari con altre destinazioni d’uso
Principios generales de la responsabilidad objetiva por riesgo
No full textEl trabajo aborda en general las reglas y principios que configuran la responsabilidad objetiva en el Código Civil y Comercial. El riesgo creado opera como norma de cierre de la responsabilidad objetiva. El art. 1757 del Código Civil y Comercial constituye la norma de reenvío a la queremiten las disposiciones específicas de otras responsabilidades especiales o agravadas, tanto del sistema general de la responsabilidad civil como delas leyes especiales y de los microsistemas. Sus directivas constituyen laplataforma a la cual debe acudirse para delimitar y completar la responsabilidadobjetiva prevista en los diferentes microsistemas.Fil: Galdós, Jorge.

Los usos creativos de obras artísticas frente al derecho de autor
No full textEl trabajo comenta un fallo sobre derechos de autor. El casosirve para abordar la cuestión de los usos creativos de las obras artísticasy literarias, en particular los casos en que un creador utiliza parasu composición una obra precedente. Este tipo de prácticas no sonnuevas pero las nuevas tecnologías las ha potenciado, obligando así arepensar el rol que cumplirá el derecho frente a este nuevo contexto.El escenario actual presenta una tensión entre el mundo artístico, quelegitima tales prácticas, y el mundo jurídico, que -como en el fallo enanálisis- las condena. De allí que, sobre el nal del trabajo, se proponeuna revisión de los postulados tradicionales del derecho de autor y sesugiere la incorporación de una nueva excepción al derecho de autor:la excepción de usos creativos.In the paper we comment a decision on copyright. The subject serves to approach the issue of creative uses of artistic and literary works, particularly where the creator use a previous work. Such practices are not new but the new technologies have boosted that, thereby forcing us to rethink the role of law in the new context. The current situation presents a tension between the art world, which legitimizes such practices, and the law world, who -was in the decision in analysis-, interdicted it. Hence, on the end of the paper, we propose a review of the traditional tenets of copyright, and we suggest the incorporation of a new exception to copyright: the exception of creative uses.Fil: Valicenti, Ezequiel Andres.

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
Climate Change: Picturing the Science
No full textDavid Downie is a contributing author (with Gavin Schmidt and Lyndon Valicenti), Preventive Planetary Care .
Book description: An unprecedented union of scientific analysis and stunning photography illustrating the effects of climate change on the global ecosystem. Going beyond the headlines, this work by leading NASA climate scientist Gavin Schmidt and master photographer Joshua Wolfe illustrates as never before the ramifications of shifting climate. Photographic spreads show retreating glaciers, sinking villages in Alaska\u27s tundra, and drying lakes. The text follows adventurous scientists through the ice caps at the poles to the coral reefs of the tropical seas. Marshaling data spanning centuries and continents, the book sparkles with cutting-edge research and visual records, including contributions from experts on atmospheric science, oceanography, paleoclimatology, technology, politics, and the polar regions. -- Publisher description.https://digitalcommons.fairfield.edu/politics-books/1014/thumbnail.jp
