PERFORMATIVITY, SOCIAL ONTOLOGY, AND THE USES OF NARRATIVES IN LATIN AMERICA

ABSTRACT: This article explains the relationship between performativity and social ontology in the case of Latin American narratives of resistance and liberation. In particular, it shows how these narratives construct social facts and provide social reality to experiences of oppression and to efforts of resistance and liberation, by means of performative functions tied to the creation and maintenance of social ontologies and to the struggle for identity, social recognition, sources of legitimacy, and hegemony. Latin America is not singular in the use of these kinds of narratives but it is special in the centrality that it gives to them and in its awareness of it. By way of example, the article touches upon four narratives that displa

Fully Automated Fact Checking Using External Sources

Given the constantly growing proliferation of false claims online in recent years, there has been also a growing research interest in automatically distinguishing false rumors from factually true claims. Here, we propose a general-purpose framework for fully-automatic fact checking using external sources, tapping the potential of the entire Web as a knowledge source to confirm or reject a claim. Our framework uses a deep neural network with LSTM text encoding to combine semantic kernels with task-specific embeddings that encode a claim together with pieces of potentially-relevant text fragments from the Web, taking the source reliability into account. The evaluation results show good performance on two different tasks and datasets: (i) rumor detection and (ii) fact checking of the answers to a question in community question answering forums.Comment: RANLP-201

Confirming Presence and Mobilization of Partner Quality Genes in Sinorhizobium meliloti

Mutualism is an interaction in which two organisms benefit from each other. The symbiotic relationship between the bacterium Sinorhizobium meliloti and the plant Medicago truncatula is dictated by the bacterial plasmids. The Heath lab has a collection of 191 Sinorhizobium meliloti strains with different symbiotic plasmids that vary across populations (Riley et al., 2022). Each strain can be a better or worse partner for its plant host in symbiosis with the variation in fitness being called partner quality (Fig. 1) These traits can be traced back to the genetic elements that underlie this effect (Batstone et al., These genetic elements can be found in gene clusters that are gained or loss across strains (Fig. 1; Riaz, Sosa Marquez, in prep.). We need assurances of these important and variable clusters presence to understand their mechanism of gene movemen

Detailed experimental and numerical analysis of hydrodynamics in the outflow measurement channel of a sewage treatment plant

The 'Bajo Grande' Wastewater Treatment Plant has a design capacity of 2.78 m3/s, and discharges into the Suquia River (Córdoba, Argentina). The river has an average flow rate of 10 m3/s, with lower values during the summer. Currently, the treatment plant does not have an accurate discharge-measurement system prior to the discharge into the river, which makes it difficult to evaluate the dosing of the disinfection treatment. The outflow rate is measured in a straight flume. However, at the inlet section of the flume, a 180° sharp bend induces a complex turbulent flow with instabilities and low-frequency velocity fluctuations which are not appropriate for flow quantification. In this type of flow, most of the in situ flow discharge-measurement systems have great uncertainty. Therefore, in situ flow measurements with an Acoustic Doppler Current Profiler, Large-Scale Particle-Tracking Velocimetry techniques and a prototype-scale Detached Eddy Simulation model were combined to obtain a detailed characterization of the turbulent flow. The results provide flow rates, fields of mean flow velocity, temporal evolution, and characteristic parameters of the turbulence. This allowed a better understanding of the effects of turbulence and flow instabilities. The results provide a basis to validate numerical models used in the hydraulics design of contact chambers to improve the disinfection process.Fil: Ragessi, Ivan Matias.

Response of layer hens to different densities in cages and dietary energy levels

Harco Sex Link layers were used to evaluate the effects of three population densities in cages (DPJ; 600, 480, and 450 cm 2/hen) using cages of three sizes (30 x 40, 36 x 40, and 45 x 30 cm), in which were housed 2, 3, and 3 birds/cage, resulting in 15, 12, and 15 cm of lineal feeder space per bird, respectively; and two levels of dietary energy (NED; 2 600 and 2 800 kcal ME/kg) and their interaction, on feed consumption (ConA), laying percentage (PP), weight per egg (PH), and feed conversion (CA), in a 12-wk trial conducted at La Tuquerena Farm. A completely randomized design was used, with a factorial arrangement (3 x 2) and six replications per treatment. DPJ exerted effects (P < 0.05) on ConA and PP, the highest values (128.9 g/day and 65.4%) corresponding to the 600 cm2 density, whereas PH and CA were not affected. NED did not affect (P < 0.05) ConA (although trend was to higher consumption at the lower NED) nor PP and PH; the higher NED gave better (P < 0.05) efficiency in CA (expressed as 2.36 vs. 2.59 kg feed/dozen eggs or 1.91 vs. 1.96 kg/kg). The DPJ–NED interaction affected (P < 0.05) ConA, PP and CA, but not PH (treatment means of which varied only between 64.2 and 62.3 g). Highest ConA (130.4 g/day) and PP (64.6%) were obtained with the combination 600 cm 2/bird and 2 600 kcal/kg, lowest ConA (114.5 g) with 480–2 800 and lowest PP (52.1%) with 480–2 600. The best CA (kg/dozen) were 2.30 for 450–2 800 and 2.34 for 480–2 800 and the worst 2.67 (480–2 600) and 2.64 (450–2 600). The 2 600 energy level was satisfactory for use with the 600 cm 2/hen density, but at the higher densities its use resulted in lower PP and poorer CA than the 2 800 kcal/kg level

Embedding Computer Simulation Based Classroom Activities to Enhance the Learning Experience for Manufacturing Systems

In recent time, manufacturing environment are bracing higher end technologies to achieve high productivity, efficiency and effectiveness. Due to the adoption of the sophisticated technologies, the system is becoming very complex and stochastic. Moreover, the manufacturing system is interconnected among its different subsystems and components, which cannot be described only through the theoretical explanation. Here, computer simulation can be integrated to design and visualize the stochastic and complex system. This paper uses the advantage of simulation to describe a series classroom activity using SIMIO software, which are deployed in industrial systems simulation course in the University of Texas at El Paso. Besides, the authors show a noble approach to demonstrate the simulation using the virtual reality (VR) technology in Unity platform. Integration of these simulation based classroom activities provide three-fold benefit to students’ learning process; (1) it provides an effective way to evaluate the design and operational performance of manufacturing systems, (2) students can experience the real time situation by imitating a manufacturing environment, and (3) it motivates the students to be engaged in the classroom activities besides learning the theoretical knowledge

Tuple MapReduce and Pangool: an associated implementation

This paper presents Tuple MapReduce, a new foundational model extending MapReduce with the notion of tuples. Tuple MapReduce allows to bridge the gap between the low-level constructs provided by MapReduce and higher-level needs required by programmers, such as compound records, sorting, or joins. This paper shows as well Pangool, an open-source framework implementing Tuple MapReduce. Pangool eases the design and implementation of applications based on MapReduce and increases their flexibility, still maintaining Hadoop's performance. Additionally, this paper shows: pseudo-codes for relational joins, rollup, and the PageRank algorithm; a Pangool's code example; benchmark results comparing Pangool with existing approaches; reports from users of Pangool in industry; and the description of a distributed database exploiting Pangool. These results show that Tuple MapReduce can be used as a direct, better-suited replacement of the MapReduce model in current implementations without the need of modifying key system fundamentals
