Pavilhão 24 da Feira da América (1954): uma abordagem biográfica

Held during the second presidential term of Juan Domingo Perón, in Mendoza, the Fair of the Americas (1954) took place. It was a continental exhibition that sought to promote regional production and strengthen Argentina's commercial and international relations with neighboring countries. It was also praised as an attractive event for visitors and locals. Likewise, it stood out as a space for international competition, given that stands from industries, business chambers, and chambers of commerce took part in the call. Conceived as elements of ephemeral architecture, the pavilions designed for the Fair displayed the disciplinary precepts typical of their time. Recent research has sought to account for the historical and symbolic relevance of this event for the region, as well as the disciplinary debates on Architecture and Design, that led to this international gathering. In this framework, this article aims to study the case of the only material testimony of the Fair that still stands, starting from a critical-analytical reading of the project documentation and of the architectural work as a messenger, considering the professional backgrounds of the technical players involved with its conception and materialization.Realizada durante a segunda presidência de Juan Domingo Perón em Mendoza, a Feria de América (1954) foi uma mostra continental que buscou promover as produções regionais e fortalecer as relações comerciais e internacionais da Argentina com os países vizinhos, além de ser elogiada como um evento de atração de visitantes e da população local. Da mesma forma, destacou-se como espaço de competição internacional, uma vez que foram apresentados a concurso stands de indústrias, câmaras empresariais e de comércio. Concebidos como elementos de arquitetura efêmera, os pavilhões projetados para a Feira levantaram os preceitos disciplinares típicos de sua época. Pesquisas recentes têm procurado dar conta da relevância histórica e simbólica deste evento para a região; bem como os debates disciplinares que, em torno da Arquitetura e do Design, provocaram este encontro internacional. Nesse contexto, o artigo visa abordar o caso do único testemunho material da Feira que permanece de pé, a partir de uma leitura crítico-analítica da documentação do projeto e da obra como portadora de mensagens, considerando as trajetórias profissionais dos agentes técnicos envolvidos em sua ideação e materialização.Realizada durante la segunda presidencia de Juan Domingo Perón en Mendoza, la Feria de América (1954) fue una exposición continental que buscó fomentar la producción regional y afianzar las relaciones comerciales e internacionales de Argentina con los países vecinos, además de ensalzarse como evento de atracción para visitantes y locales.

Is three better than one? simulating the effect of reviewer selection and behavior on the quality and efficiency of peer review

This paper looks at the effect of multiple reviewers and their behavior on the quality and efficiency of peer review. By extending a previous model, we tested various reviewer behavior, fair, random and strategic, and examined the impact of selecting multiple reviewers for the same author submission. We found that, when reviewer reliability is random or reviewers behave strategically, involving more than one reviewer per submission reduces evaluation bias. However, if scientists review scrupulously, multiple reviewers require an abnormal resource drain at the system level from research activities towards reviewing. This implies that reviewer selection mechanisms that protect the quality of the process against reviewer misbehavior might be economically unsustainable

Insight into Acid−Base Nucleation Experiments by Comparison of the Chemical Composition of Positive, Negative, and Neutral Clusters

We investigated the nucleation of sulfuric acid together with two bases (ammonia and dimethylamine), at the CLOUD chamber at CERN. The chemical composition of positive, negative, and neutral clusters was studied using three Atmospheric Pressure interface-Time Of Flight (APi-TOF) mass spectrometers: two were operated in positive and negative mode to detect the chamber ions, while the third was equipped with a nitrate ion chemical ionization source allowing detection of neutral clusters. Taking into account the possible fragmentation that can happen during the charging of the ions or within the first stage of the mass spectrometer, the cluster formation proceeded via essentially one-to-one acid−base addition for all of the clusters, independent of the type of the base. For the positive clusters, the charge is carried by one excess protonated base, while for the negative clusters it is carried by a deprotonated acid; the same is true for the neutral clusters after these have been ionized. During the experiments involving sulfuric acid and dimethylamine, it was possible to study the appearance time for all the clusters (positive, negative, and neutral). It appeared that, after the formation of the clusters containing three molecules of sulfuric acid, the clusters grow at a similar speed, independent of their charge. The growth rate is then probably limited by the arrival rate of sulfuric acid or cluster−cluster collision

A Dynamic Performance Management Approach to Evaluate and Support SMEs Competitiveness: Evidences from a Case Study

The role of Performance Management (PM) systems has become crucial for steering Small-Medium Enterprises (SMEs) to successfully compete during the ongoing critical economic transition. To improve decision-maker strategic learning processes, traditional PM frameworks need to be combined with System Dynamics (SD) modeling. This paper shows how to design and use a Dynamic Performance Management (DPM) approach to assess and support SMEs competitiveness. The emerging framework is applied to a real case of a small business to analyze the empirical effectiveness of the approach hereby suggested
