Los pobres y la pobreza en las agendas municipales: acciones y discusiones en el centro y sur de la provincia de Buenos Aires entre 1913 y 1920
Authors: De Paz Trueba Yolanda , Bracamonte Lucía 
Published: May 2022

En el marco de los dilemas que la pobreza y los diversos problemas sociales vinculados a ella plantearon a quienes debieron gestionar medidas al respecto entre 1913 y 1920 en el nivel municipal, este trabajo busca observar los sutiles desplazamientos que se dieron en la idea de responsabilidad del Estado sobre las cuestiones sociales. Buscamos examinar de qué manera la percepción de las desigualdades marcó las agendas municipales de la región estudiada, afectando la manera de resolver las necesidades pero sobre todo la concepción de la función política en ello.
Sostenemos que muchas de esas soluciones superaron la coyuntura al poner en agenda lo social como problema público y político, si bien no mermó el protagonismo de las instituciones filantrópicas que tradicionalmente habían atendido a estas cuestiones.
Centramos la pesquisa en la manera en que aquellos que debieron ofrecer resultados, pensaron la pobreza en el marco de una agenda de problemas ampliada y procuramos ir más allá de las concreciones para analizar las discusiones generadas alrededor de la búsqueda de paliativos y observar de qué manera la crisis instaló en el debate la cuestión de las responsabilidades sociales y públicas por la pobreza en un momento de transición política.

Abstract
This paper reports the effectiveness of a novel imaging system, piezoelectric and laser ultrasonic system (PLUS), for the three-dimensional (3D) imaging of fatigue cracks with a high-resolution. The PLUS combines a piezoelectric transmitter and the two-dimensional (2D) mechanical scanning of a laser Doppler vibrometer, enabling the 2D matrix array with an ultra-multiple number of receiving points for 3D phased array imaging. After describing the principle and 3D imaging algorithm of PLUS, we show the fundamental 3D imaging capability of the PLUS in a flat-bottom-hole specimen with varying the number of receiving points under a fixed large receiving aperture. We then demonstrate that the PLUS with 4275 receiving points (i.e. 75 × 57) achieves high-resolution 3D imaging of a fatigue crack with a high signal-to-noise ratio, providing the outline of the fatigue crack geometry. We also discuss the effectiveness of the ultra-multiple receiving points for suppressing grating lobes and random noise.

وردت الكتابة في شعر ما قبل الاسلام في موضوع الطلل فشبه الشاعر آثار الطلل التي انمحت بكتاب انمحت سطوره، وتطور مدلول (لفظة الكتابة) في العصر الاسلامي حتى شمل الكتاب المنزل من الله سبحانه وتعالى، وجدد الشاعر في مدلول الكتابة في العصر الأموي ليشمل كتابة الرسائل الشعرية، ودلت الكتابة في موضوع الهجاء على ثبوت صفات المهجو كما تثبت الكتابة والختم، أما في موضوع المدح، فدلّ على تبليغ رسائل الخليفة وبعضها فيها مبالغة. وتطور مدلول الكتابة في العصر العباسي. فأصبح موضوعا شعريا يصف صعوبة الكتابة، وبيان الجهد الذي يبذله الشاعر في إصلاح أشعاره. وتطور معنى (الكتابة) عند أبي نواس فحوله من معنى عقلي مجرد الى معنى حسي غزلي يتسم بالجمال، فأبو نواس يحب الجارية المولعة بالكتب وربط بين الغناء والكتابة فالغناء جهر بسرّ العاشقين، أما الكتابة، فجهر بسرّ الكاتب، وشبه جمال المحبوب بالكتابة، ثمّ شبه خُصل الشَّعر المتدلية من أعلى الأُذن بخط القلم، وشبه أبو نواس خطوط الخمرة حين تمزج بالماء بالكتابة بيد الأعسر، وافتخر أن الملائكة تكتب الذنوب عليه، وهو لا يبالي لشدة إحساسه باللذة، وشبه في موضوع الصيد ريش الدجاج بأسطر الكتابة. ووصف الكتابة بالخلود.

Deep Contextual Bandit and Reinforcement Learning for IRS-assisted MU-MIMO Systems
Authors: Pereira-Ruisánchez Dariel , Fresnedo Óscar , Pérez-Adán Darian , Castedo Luis 
Published: May 2022

<p> The combination of multiple-input multiple-output (MIMO) and intelligent reflecting surfaces (IRSs) is foreseen as a key enabler of beyond 5G (B5G) and 6G. In this work, two different approaches are considered for the joint optimization of the IRS phase-shift matrix and MIMO precoders of an IRS-assisted multi-stream (MS) multi-user MIMO (MU-MIMO) system with the aim of maximizing the system sum-rate for every channel realization. The first one is a novel contextual bandit (CB) approach with continuous state and action spaces called deep contextual bandit-oriented deep deterministic policy gradient (DCB-DDPG). The second is an innovative deep reinforcement learning (DRL) formulation where the states, actions and rewards are selected such that the Markov decision process (MDP) property of reinforcement learning (RL) is properly met. Both proposals perform remarkably better than state-of-the-art heuristic methods in high multi-user interference scenarios. </p>
Risk Assessment of Post-Fault Temporary Overvoltage Using Generalized Short-Circuit Ratio
Authors: Xin Huanhai , liu xinyu , Zheng Di , Chen Dong , Zhou Yuhan , Marshall Benjamin 
Published: May 2022

<p>Temporary overvoltage (TOV) is becoming one challenge for the integration of significant power electronics resources into a power system. To assess the risk of TOV in a Multi-Infeed Power Electronic System (MIPES), a worst-case estimation approach is proposed to assess TOV risk. The paper starts with analyzing the mechanism of TOV, which reveals that TOV is dominated by excessive reactive power resulting from control lagging of converters. Then, the principle of approximating the TOV for a Voltage Source Converter (VSC) connecting to an infinite bus is introduced within the context of the RMS model. After that, a methodology based on the concept of generalized short-circuit ratio for overvoltage (gSCR-TOV) is introduced to quantify the risk of TOV in a multi-bus system. The intent of this concept is to permit screening to identify those nodes at greatest need for further EMT assessment. To localize these nodes, a concept of weighted sensitivity matrix is further proposed to pinpoint the bus subject to highest TOV in a MIPES. Finally, case studies of EMT time-domain simulations are carried out and verifies the effectiveness of the proposed methodologies. </p>

AN ANALYSIS OF STUDENTS’ WRITING ASSIGNMENT OF ANALYTICAL EXPOSITION TEXT
Authors: Zuana Muhammad Mujtaba Mitra 
Published: May 2022

Writing is not always easy to do. The students face some difficulties in mastering writing skill because they need particular practice to develop their writing skill. The teacher should know the students’ abilities and difficulties toward this skill and one of many ways teacher can do is by analyzing students’ compositions. In this research, they are generic structures and language features of analytical exposition texts. They may make students find some difficulties in analytical exposition texts.
This study is descriptive qualitative study and this research is aiming to describe the students’ competence in writing expository text. The researcher is the first instrument and the second instrument for this study is the students’ compositions of analytical exposition texts. To analyze the data, there will be three steps; classification, analysis, and representing to determine whether the students write analytical exposition text with proper generic structures and language features or not.
After being analysis, the researcher found that the students could write analytical exposition texts with a good generic structures and language features. However, there are some students who do not compose them properly. For generic structures, some students often do not write review of arguments in thesis and reiteration. And for language features, some of the students often do not apply the diction well. The students are proficient enough in organizing analytical exposition text in term of generic structures and language features.
From the analysis, the abilities and difficulties of the students can be identified by the teacher. The teacher should give clear explanation and understanding in teaching analytical exposition text. The teacher had to explain about how to make analytical exposition text deeply in order that the students could comprehend the text well. In addition, the English teacher could give comments to the students’ composition for the better next writing assignments, because they will know about the mistakes that they still made.

ESP Students’ Preferences in Learning English: Face to Face Corrective Feedback vs Online Corrective Feedback
Authors: Ferdian Nurizzi Rifqi 
Published: May 2022

ABSTRACT
The current study aims to explore the students’ preferences on face to face corrective feedback vs online corrective feedback in ESP class. It is an attempt to investigate if they prefer to be corrected directly face to face by teachers or they like to be provided online corrective feedback by the teachers. To do so, a questionnaire was distributed to a group of students who are taking English for Specific Purposes and also focus group discussion was used in order to find out their beliefs toward their corrective feedback preferences. Totally, 50 students who were taking ESP courses at State Polytechnic of Subang participated in this study. The results from the questionnaire analysis revealed that the students preferred their teachers to use face to face corrective feedback, with an overall mean (x̄ = 3,95) in learning effectiveness, (x̄ = 4,12) in learning accuracies, and (x̄ = 4,02) in learning experiences. The focus group discussion revealed the students’ beliefs in their corrective feedback preferences, they believed that the teachers should be able to guide their learning, use communicative ways, and encourage them by using their learning preferences. The study suggested that taking these preferences into consideration could help students to increase their confidence in learning English.

This research was conducted by descriptive qualitative where the subject is seventh English Department students in Nommensen University academic year 2019/2020 on Seminar Class and the data is students’questions. After analizing questions, it was found that Socratic questions used by the seventh semester of English students in FKIP UHN Medan are questions and clarification, questions that prope purposes, questions that probe assumptions, Question that Probe Information, Reason, Evidence, and Cause, Question about viewpoints or perspectives, Questions that Probe Implication and Consequences, Question about question, Question that Probe Concept, and Questions that probe Inferences and Interpretation. The most dominant is Question that Probe Information, Reason, Evidence, and Cause. It means that the students’ ability in making questions in seminar on ELT presentation is still on the level of getting information from the text, less to have capacity to view or to judge things from some other perspectives, less of preparing themselves reading the seminar paper before the presentation starts. The writer assumed that the students lack of reading.
CYBERCRIME: MODERN TYPES, CAUSES GENERATING AND FEATURES OF PREVENTION
Authors: Кобец Петр Николаевич 
Published: May 2022

Рост киберпреступлений в нашей стране свидетельствует о том, что российское население все еще в недостаточной степени информировано относительно рисков, связанных с цифровизацией общества, проявляющихся в киберпреступности, поэтому автор посчитал необходимым предпринять шаги по повышению компетентности российского общества о возможностях киберпреступников. В статье проанализирована современная киберпреступность, которая в первую очередь проявляется в использовании преступниками вредоносных компьютерных программ в целях хищения и дальнейшего использования персональных данных пользователей и организаций. Также опасны и другие ее виды, угрожающие цифровому доверию и безопасности россиян. Сделан вывод о том, что современные кибератаки требуют коллективного и скоординированного противодействия на основе таких стратегических приоритетов, как комплексное повышение фундаментальных основ информационной безопасности, а также совершенствование безопасности правоохранительных и иных государственных информационных систем и критических инфраструктур.
The growth of cybercrimes in our country indicates that the Russian population is still insufficiently informed about the risks associated with the digitalization of society manifested in cybercrime, therefore the author considered it necessary to take steps to increase the competence of the Russian society about the possibilities of cybercriminals. The article analyzes modern cybercrime, which primarily manifests itself in the use of malicious computer programs by criminals in order to steal and further use personal data of users and organizations, and other types of it that threaten the digital trust and safety of Russians are also dangerous. It is concluded that modern cyberattacks require collective and coordinated counteraction based on such strategic priorities as a comprehensive increase in the fundamental foundations of information security, as well as improving the security of law enforcement and other state information systems and critical infrastructures.
Exploring the effectiveness of auditory, visual, and audio-visual sensory cues in a multiple object tracking environment

Published: May 2022

AbstractMaintaining object correspondence among multiple moving objects is an essential task of the perceptual system in many everyday life activities. A substantial body of research has confirmed that observers are able to track multiple target objects amongst identical distractors based only on their spatiotemporal information. However, naturalistic tasks typically involve the integration of information from more than one modality, and there is limited research investigating whether auditory and audio-visual cues improve tracking. In two experiments, we asked participants to track either five target objects or three versus five target objects amongst similarly indistinguishable distractor objects for 14 s. During the tracking interval, the target objects bounced occasionally against the boundary of a centralised orange circle. A visual cue, an auditory cue, neither or both coincided with these collisions. Following the motion interval, the participants were asked to indicate all target objects. Across both experiments and both set sizes, our results indicated that visual and auditory cues increased tracking accuracy although visual cues were more effective than auditory cues. Audio-visual cues, however, did not increase tracking performance beyond the level of purely visual cues for both high and low load conditions. We discuss the theoretical implications of our findings for multiple object tracking as well as for the principles of multisensory integration.
A mighty tool not only in perception: Figure-ground mechanisms control binding and retrieval alike
Authors: Schmalbrock Philip , Frings Christian 
Published: May 2022

AbstractStimulus and response features are linked together into an event file when a response is made towards a stimulus. If some or all linked features repeat, the whole event file (including the previous response) is retrieved, thereby affecting current performance (as measured in so-called binding effects). Applying the figure-ground segmentation principle to such action control experiments, previous research showed that only stimulus features that have a figure-like character led to binding effects, while features in the background did not. Against the background of recent theorizing, integration and retrieval are discussed as separate processes that independently contribute to binding effects (BRAC framework). Thus, previous research did not specify whether figure-ground manipulations exert their modulating influence on integration and/or retrieval. We tested this in three experiments. Participants worked through a sequential distractor-response binding (DRB) task, allowing measurement of binding effects between responses and distractor (color) features. Importantly, we manipulated whether the distractor color was presented as a background feature or as a figure feature. In contrast to previous experiments, we applied this manipulation only to prime displays (Experiment 1), only to probe display (Experiment 2), or varied the figure-ground manipulation orthogonally for primes and probes (Experiment 3). Together the results of all three experiments suggest that figure-ground segmentation affects DRB effects on top of encoding specificity, and that especially the retrieval process is affected by this manipulation.
