Authors: Sánchez Cañas Paula Michelle , Yépez Herrera Emerson Roberto
Published: December 2021

Esta investigación tiene como fin establecer la incidencia de la ansiedad en competencia por la que atraviesan los deportistas adaptados del Club Boccias Ecuador, se tomó como punto de partida la falta de preparación psicológica dentro del entrenamiento, en este caso resulta primordial determinar un análisis en torno a esta realidad ya que son deportistas con parálisis cerebral que se mantienen activos dentro del campo competitivo y que de esta forma alcanzaron instancias del deporte paralímpico, el objetivo se centra en realizar un estudio exploratorio por ser el primero en el país, con la aplicación de una investigación de campo. Como herramienta de recolección de datos se hizo uso del cuestionario psicométrico de ansiedad precompetitiva CSAI-2R en su traducción y adaptación al español, con una escala de Likert de cuatro puntas, el mismo que se recogió bajo consentimiento de los representantes legales de los deportistas. El análisis cuantitativo se ejecutó a través del programa SPSS.22 donde los parámetros que se tomaron en consideración fueron los factores de ansiedad como ansiedad cognitiva, ansiedad somática sentido y ansiedad somática física, lo que arrojó como resultado que estos factores no inciden en el rendimiento de los deportistas adaptados de boccia en etapa competitiva, algo muy positivo en la preparación deportiva sin embargo, es de alta relevancia tener en cuenta las características de su clasificación de discapacidad, su forma de percepción ante esta condición del organismo que, en efecto, puede ser muy diferente a la adoptada por otro tipo de deportista, lo que se traduce en una posible ventaja al momento del manejo de la ansiedad en competencias que marcan el avance de su carrera deportiva y con ello les permite un óptimo desempeño competitivo.
Sobre sucesiones de Sidon
Authors: Infante Adrian
Published: December 2021

Estudiamos los subconjuntos de números reales con la propiedad de que todas las sumas de dos elementos son distintos, es decir que si 𝑎𝑖 + 𝑎𝑗= 𝑎𝑖′+ 𝑎𝑗′ entonces se verifica la igualdad {𝑎′}. A estos conjuntos los llamaremos conjuntos de Sidon. El problema es saber cuál es el mayor número de elementos que puede tener un conjunto de Sidon 𝑖, 𝑎𝑗} = {𝑎𝑖′, 𝑎𝑗 en el intervalo [1, 𝑁]. Presentamos ejemplos que evidencian la necesidad de conocer el tamaño del intervalo [1, 𝑁] donde se va a ubicar el conjunto de Sidon para saber el tamaño 𝐹(𝑁) del conjunto de Sidon. Ruzsa I. Z. (1998) demostró la existencia de una sucesión infinita de Sidon tal que su tamaño 𝐵(𝑁)> 𝑁√2−1+𝑜(1). En este trabajo rehacemos detalladamente la demostración de Ruzsa, introduciendo en la prueba una modificación sustancial, al sustituir las sucesiones {log 𝑝} por la sucesión de los argumentos de los enteros de Gauss 𝑎 + 𝑖𝑏 = 𝑝 con 0 < 𝑎 < 𝑏, 𝑎 y 𝑏 enteros y 𝑝 primo.

Abstract

We study the sub-sets of real numbers with the property that all sums of two elements is different, namely 𝑎+𝑎𝑗′ then the equation {𝑎′} is verified. We will call these sets Sidon sets. The problem is knowing the maximum number of elements that a Sidon set can contain in the interval [1, 𝑁]. We present examples that show the need 𝑖, 𝑎𝑗} = {𝑎𝑖′, 𝑎𝑗 of knowing the size of the interval [1, 𝑁] where the Sidon set will be located to know the size 𝐹(𝑁) of the Sidon set. Ruzsa I. Z. (1998) proved the existence of an infinite Sidon succession such that its size 𝐵 ( 𝑁 ) > 𝑁. In this paper, we rewrite Ruzsa proof in detail, introducing a substantial modification in the proof, by substituting the successions for the succession of the arguments of Gauss integers 𝑎 + 𝑖𝑏 = 𝑝 with 0 < 𝑎 < 𝑏, 𝑎 and 𝑏 integers and 𝑝 prime. {log 𝑝} 𝑝, 𝑟𝑖𝑚𝑜

Explainable Biomarkers for Automated Glomerular and Patient-Level Disease Classification
Authors: Basso Matthew Nicholas , Barua Moumita , John Rohan , Khademi April
Published: December 2021

Key Points

A software tool was developed to perform glomerular and patient-level classification on the basis of clinically relevant biomarkers.

Ten biomarkers were used for glomerular and patient-level classification that obtained 77% and 87% accuracies, respectively.

In the future, these tools can be applied to clinical datasets for glomerular biomarker discovery and for insights into disease mechanisms.

Pathologists use multiple microscopy modalities to assess renal biopsy specimens. Besides usual diagnostic features, some changes are too subtle to be properly defined. Computational approaches have the potential to systematically quantitate subvisual clues, provide pathogenetic insight, and link to clinical outcomes. To this end, a proof-of-principle study is presented demonstrating that explainable biomarkers through machine learning can distinguish between glomerular disorders at the light-microscopy level.

The proposed system used image analysis techniques and extracted 233 explainable biomarkers related to color, morphology, and microstructural texture. Traditional machine learning was then used to classify minimal change disease (MCD), membranous nephropathy (MN), and thin basement membrane nephropathy (TBMN) diseases on a glomerular and patient-level basis.

The final model combined the Gini feature importance set and linear discriminant analysis classifier. Six morphologic (nuclei-to-glomerular tuft area, nuclei-to-glomerular area, glomerular tuft thickness greater than ten, glomerular tuft thickness greater than three, total glomerular tuft thickness, and glomerular circularity) and four microstructural texture features (luminal contrast using wavelets, nuclei energy using wavelets, nuclei variance using color vector LBP, and glomerular correlation using GLCM) were, together, the best performing biomarkers. Accuracies of 77% and 87% were obtained for glomerular and patient-level classification, respectively.

Computational methods, using explainable glomerular biomarkers, have diagnostic value and are compatible with our existing knowledge of disease pathogenesis. Furthermore, this algorithm can be applied to clinical datasets for novel prognostic and mechanistic biomarker discovery.
A Case of Shifting Focus Friction: Extension Directors and State 4-H Program Leaders’ Perspectives on 4-H LGBTQ+ Inclusion
Authors: Elliott-Engel Jeremy , Westfall-Rudd Donna , Kaufman Eric , Seibel Megan , Radhakrishna Rama
Published: December 2021

Contemporary Lesbian, Gay, Bisexual, Transgender, Queer/Questioning (LGBTQ+) youth are identifying and communicating their identities earlier in childhood than generations before as a result of more awareness and more acceptance of gender identity and sexual minorities by society. A qualitative study of U.S. 4-H program leaders and Extension directors generated an emergent theme around the importance of serving LGBT youth and the resulting implementation challenges. The administrators of 4-H, the largest youth serving organization in the country, recognize the presence of LGBTQ+ youth in 4-H and believe the organization must be inclusive. But challenges remain in ensuring youth experience inclusion at all levels of the organization and to manage political and societal pressures resulting from shifting focus friction.

Published: December 2021

Se evaluaron insecticidas comerciales de bajo impacto ambiental para el control de Diaphorina citri en el cultivo de limón mexicano en el Valle de Apatzingán, Michoacán, México. Se utilizó un diseño completamente al azar con doce tratamientos (insecticidas) y diez repeticiones, la unidad experimental fue un árbol. La técnica para la recolección de datos en campo fue el “muestreo por golpeteo”. La toma de datos se realizó en premuestreo como punto de inicio y comparación y después se llevaron a cabo los muestreos a los 3, 6, 12, 20, 26, 35 y 41 días. Para el análisis de datos se empleó la prueba Post Hoc de homogeneidad de datos de las varianzas, ANDEVA y la prueba de comparación de medias de Tukey (P≤ 0,05). Se observó que el Tolfenpyrad, mantuvo una efectividad constante durante todos los muestreos, al reducir la población de psílidos en un 95,65 %. El Pyrifluquinazon al inicio disminuyó de 4,9 en pre muestro a 0,6 psílidos a los 3 días después de la aplicación, equivalente a un 87,75% de reducción. El Fenpyroximato, mostró ser un insecticida eficaz, al presentar un rango de reducción de la población de psílidos de 40,32 a 83,87% en todos los muestreos. Se concluye que, el Tolfenpyrad y el Fenpyroximato son moléculas químicas de nueva generación que evidencian una mortalidad de adultos del psílido alta, por lo que son una alternativa viable para el manejo de la plaga en la región del Valle de Apatzingán, Michoacán.

Published: December 2021

Ante la irrupción de nuevos soportes informativos, analizamos la comunicación pública de la ciencia en los diarios digitales de Argentina (2017-18) con respecto a la temática de salud, en las dimensiones claves de la producción periodística, la jerarquización noticiosa y el tratamiento de las fuentes. La finalidad es determinar regularidades y particularidades en el volumen y despliegue informativo que recibe la ciencia en general y de la salud, en particular. En este artículo, se exponen resultados que tienen como propósito conformar un escenario de la cobertura periodística sobre ciencia enlos diarios de mayor representatividad de las regiones del país, a partir del análisis de contenido sobre una muestra de semana construida. Al respecto, nuestra hipótesis es que la cobertura periodística sobre la salud es dominante a nivel nacional debido a una mirada utilitaria sobre la ciencia queenfatiza la exposición de resultados concretos. La relevancia en el abordaje de la salud no solo se observa en cantidad de ítems noticiosos, sino que implica una mayor visibilidad y un tratamiento de fuentes que prioriza la consulta a especialistas antes que a documentos y la procedencia internacional en detrimento de las fuentes locales.
Yoğun Bakım Ünitesinde Takip Edilen Kafa Travmalı Hastaların Geriye Dönük Olarak Değerlendirilmesi ve Risk Skorlarının Prognoza Etkisi
Authors: BİNGÖL TANRIVERDİ Tuğba , ENGİN Taner
Published: December 2021

Amaç: Kafa travması sık görülen ve yoğun bakım takibi gerektirebilen önemli bir halk sağlığı problemidir. İlerleyen teknolojiler ve yoğun tedavilere rağmen kafa travması geçiren hastaların prognozu kötüdür ve çoğunda sekel ve/veya ölüm gözlenmektedir. Bu nedenle, kafa travmalarında kötü prognoza sahip olan yüksek riskli hastaları belirleyebilmek önemlidir. Glaskow koma skalası (GKS), yaralanma şiddet skoru (injury severity score, ISS) ve revize travma skoru (RTS) kafa travmalı hastaların ilk değerlendirmesinde olumsuz sonuçları tahmin etmede ve klinik karar vermede en çok kullanılan puanlama sistemleridir. Çalışmamız amacı kafa travması nedeniyle hastanemiz yoğun bakımında takip edilen hastaların klinik özelliklerini sunmak ve kullanılan klinik risk skorlarının hastane içi sonlanımlara etkisini saptamaktır.
Materyal ve metot: Ocak 2019 – Mayıs 2021 tarihleri arasında hastanemiz yoğun bakımında kafa travması nedeniyle takip edilen 104 hasta geriye dönük olarak çalışmamıza dahil edildi. Hastaların dosyaları, arşiv kayıtları ve hastane otomasyon kayıt sistemi ayrıntılı olarak incelendi. Tüm hastaların GKS, ISS ve RTS değerleri belirlenerek prognoza etkileri incelendi.
Bulgular: Hastaların yaş ortancası 24.5 (12.0-39.8) yıl ve 85’i (%81,7) erkek cinsiyette idi. Başvurudaki GKS ortancası 13 (9.3-15.0), ISS ortancası 25 (25-41), RTS ortancası ise 11 (9-12) olarak tespit edildi. 19-64 yaş aralığı dışındaki diğer tüm yaş kategorilerinde kafa travmasının en sık nedeni yüksekten düşme idi. Ancak, bu yaş aralığında en sık neden patlama veya ateşli silah yaralanması (%31.4) idi. Hastane içi ölüm 16 (%15.4) hastada meydana geldi. Hastane içi ölüm gelişmeyen hastalar ile karşılaştırıldığında; ölüm gelişen hastaların başvuru sırasındaki ISS değerleri anlamlı olarak daha yüksek iken (P<0.001), RTS (P<0.001) ve GKS (P<0.001) değerleri anlamlı olarak daha düşük idi. RTS’nin hastane içi ölümü öngördürmedeki AUC değeri (0.968), ISS (0.947) ve GKS’nin (0.866) AUC değerlerinden daha yüksek olarak tespit edildi.
Sonuç: Çalışmamızda, yoğun bakımda yatan kafa travmalı hastalarda günlük pratikte en çok kullanılan risk skorlarının hastane içi ölümü öngörmedeki rolleri araştırıldı. Her ne kadar başvurudaki risk skorları hastane içi prognozu kötü olabilecek yüksek riskli hastaları öngörmede iyi bir tanısal değere sahip olsa da, RTS’nin diğer klinik risk skorlarına göre ölümü öngörmede daha üstün bir skor olduğu tespit edildi.
Emergence: Documents in Crisis
Authors: deFremery Wayne
Published: December 2021

This essay suggests the etymologies of emergence, emergency, and crisis create a useful framework for theorizing documents. Indeed, the overlapping semantic associations of the words allow for the idea that documents emerge in crisis. The semantic overlap also allows a means for theorizing how documents descend into crisis. Theorizing documents in crisis, the essay argues, usefully complements documentalist theories of documentary representation suggested by thinkers like Paul Otlet and Suzanne Briet, as well newer conceptualizations of documentality as conceived by Michael Buckland and Maurizio Ferraris and documentarity as described by Ronald Day.
Estudio in vitro del borde cavo periférico entre el remanente dentario tallado y coronas de disilicato de litio en relación al cemento utilizado
Authors:   , De Landaburu Antón Federico
Published: December 2021

Esta tesis doctoral es experimental y explicativa. Es un trabajo multidisciplinario, ya que para las mediciones y observación del mismo se contó con la colaboración del personal docente de la Facultad de Ingeniería de la UNLP. Los datos fueron cargados en hojas de cálculo y procesados estadísticamente aplicando el análisis de Varianza. La muestra de este trabajo está representada por 40 piezas naturales (premolares superiores) extraídos por indicaciones ortodónticas, periodontales, con movilidad de grado 3 o mayor, sin posibilidad de ferulización. En la corona clínica de las piezas dentarias se les realizo un tallado para prótesis fija para coronas libres de metal, siguiendo los principios básicos del tallado, filo de cuchillo por vestibular y chanfer por palatino.A las 40 muestras se las dividió en 2 grupos de 20 piezas cada una, denominadas Unidades Experimentales (UE), se fabricaron coronas de Disilicato de Litio mediante sistema CAD CAM a la medida de las piezas a estudiar y se las cemento, un grupo con cemento de Fosfato de Cinc y el otro con Resina Compuesta de curado dual mediante las técnicas de cementado aconsejadas por el fabricante, las coronas se fijaron a cada muestra y se las rotulo para realizar los estudios a la microscopia luego del cementado. Una vez cementadas las coronas fueron observadas por las caras vestibular y palatino a nivel del borde marginal y a través del microscopio electrónico de barrido (MEB). Se realizó el registro de todos los bordes (borde cabo periférico) y se tabularon todas las medidas para un registro final.Después de un análisis comparativo se describieron las cifras de medición que permitiódistinguir las efectividades con respecto a los cementos adhesivos y de esta manera se determinó su calidad de interfase.Teniendo en cuenta los resultadosobtenidos y discusión realizada referenciando diferentes autores nacionales e internacionales se obtuvieron las siguientes conclusiones: La Resina Dual presenta un mejor sellado en relación al cemento de fosfato de cinc. El espesor de la interfase, aunque es mejor en la resina dual, ambos cementos presentan características de espesor aceptables clínicamente por varios autores. Los datos observados al MEB sobre la discrepancia marginal de la interfase corona-diente, indicarían que ambos productos analizados para cementar las coronas, reducirían el riesgo de la microfiltración.
La anemia de la hernia hiatal del estómago
Authors:   , Scaro Josefina
Published: December 2021

Los errores de diagnóstico que origina la hernia hiatal del estómago se deben a que no se piensa en ella en razón de su relativa poca frecuencia; pero sobre todo al polimorfismo de sus manifestaciones clínicas, manifestaciones que simulan padecimientos múltiples en particular cardiopáticos, respiratorios o de distintos sectores abdominales. Recorriendo la bibliografía se advierte con qué frecuencia no se la reconoce. Cuadros engañosos desorientan el diagnóstico. Asi vemos, por ejemplo, que Cossio y Fustinoni publican cinco casos que habían sido diagnosticados de angina de pecho o infarto del miocardio. En la serie de cuarenta y siete casos estudiados por Polley se consignan como diagnósticos erróneos hechos con anterioridad: enfermedad cardíaca, colecistitis, úlcera gastroduodenal, cáncer, bronquitis, etc. Ritvo, citado por Vilaseca Sabater, refiere que a tres de diez y seis enfermos se les había extirpado la vesícula; a dos el apéndice; un paciente fué operado tres veces (apendicectomía, colecistectomía, adherencias).
CREAR DOS, TRES, MUCHOS CHE: LA INTERNACIONALIZACIÓN DE LAS IDEAS REVOLUCIONARIAS A TRAVÉS DE ERNESTO GUEVARA EN LA REVISTA TRICONTINENTAL (1967-1990)
Authors: Calvo González Patricia
Published: December 2021

Ernesto Guevara constituyó el principal catalizador del ideario revolucionario tras el año 1959, con la publicación de sus obras y la asunción del «foquismo» como doctrina y práctica en los movimientos de izquierda de la segunda mitad del siglo XX. A partir de su muerte en Bolivia en 1967, se constató el fracaso de este modelo que, no obstante, se fue adaptando para servir de concitador de voluntades alrededor del mundo. Se toma así la desaparición física del Che como punto de partida para analizar el uso de sus palabras y su imagen en la revista Tricontinental, donde ocupó un lugar preponderante desde la primera publicación del suplemento especial con su texto «Crear dos, tres… muchos Vietnam, es la consigna» en abril de 1967.
Islam and Multiculturalism in Europe
Authors: Davids Nuraan
Published: December 2021

Events such as New York’s 9/11, London’s 7/7, and Paris’ Charlie Hebdohave played dramatic roles in redirecting the focus of multiculturalism in liberal European democracies. Against a backdrop of the “failure of multiculturalism” or “multiculturalism in crisis,” liberal democracies continue to struggle and stumble in their efforts to accommodate minority groups, while simultaneously trying to sustain the primary good of the majority. One stumble appears to be the effort to “emancipate” and “democratize” Muslim women by regulating their dress code. In return, liberal democracies are accused of seeking to expunge their multicultural baggage by pursuing a particular orientation of integrationism, one that disregards selfunderstandings of religious and cultural particularities. By focusing upon this issue, this article explores why multiculturalism in Europe might be perceived as failing in its response to Muslims and Islam. In weighing the increasing levels of fear and insecurity among majority groups within a context of growing social marginalization among minority groups, I argue for a reinvocation of multiculturalism as a dialectical encounter. Such an encounter, based on mutual trust and respect, will lead to the equal citizenship necessary to counter the simmering alienation and skepticism that always threaten to undermine any notion of peaceful co-existence between majority and minority groups.
Designing a phononic crystal with a large defect to enhance elastic wave energy localization and harvesting

Published: December 2021

Phononic crystals (PnCs) have been shown to manipulate and amplify elastic waves. Using this characteristic of PnCs to assist energy harvesting has a remarkable effect. Generally, a defect occurs when a unit cell in a PnC is replaced by another cell with different geometric or material properties; then the output electric power of piezoelectric energy harvesting (PEH) devices will be significantly enhanced. In this study, a cross-hole-type PnC-assisted PEH device with a large defect is presented by replacing several adjacent cells with other cells. It is found that multiple peak voltages can be created within the bandgap and multimodal energy harvesting can be performed. Compared with the defect mode composed of a small defect, energy localization and amplification of the proposed PnC leads to substantial enhancement of harvesting power after tailoring the geometric parameters of a PEH device. This work will help in designing PnC-assisted PEH devices in a reasonable way.
Powered Knee and Ankle Prosthesis with Adaptive Control Enables Climbing Stairs with Different Stair Heights, Cadences, and Gait Patterns
Authors: Hood Sarah , Gabert Lukas , Lenzi Tommaso
Published: December 2021

Powered prostheses can enable individuals with
above-knee amputations to ascend stairs step-over-step. To accomplish this
task, available stair ascent controllers impose a pre-defined joint impedance
behavior or follow a pre-programmed position trajectory. These control approaches
have proved successful in the laboratory. However, they are not robust to
changes in stair height or cadence, which is essential for real-world
ambulation. Here we present an adaptive stair ascent controller that enables
individuals with above-knee amputations to climb stairs of varying stair
heights at their preferred cadence and with their preferred gait pattern. We
found that modulating the prosthesis knee and ankle position as a function of the
user’s thigh in swing provides toe clearance for varying stair heights. In stance,
modulating the torque-angle relationship as a function of the prosthesis knee
position at foot contact provides sufficient torque assistance for climbing stairs
of different heights. Furthermore, the proposed controller enables individuals
to climb stairs at their preferred cadence and gait pattern, such as
step-by-step, step-over-step, and two-steps. The proposed adaptive stair controller
may improve the robustness of powered prostheses to environmental and human
variance, enabling powered prostheses to more easily move from the lab to the
real-world.
A Framework to Evaluate Blockchain Interoperability Solutions

Decentralized ledger technology (DLT), in particular blockchain, is becoming ubiquitous in today's society. Just in the second quarter of 2021, centralized and decentralized exchanges had a volume of around $600 billion. Enterprises are adopting this technology, following the opportunity to expand to new businesses. However, they need to connect their existing systems and processes to blockchains securely and reliably. Blockchain interoperability (BI) is emerging as one of the crucial features of blockchain technology. Fueled by the need to eliminate data and value silos, they realize the necessary bridge between centralized and decentralized systems.

As BI is still maturing, there are many unsolved challenges. In particular, it is still difficult for developers and practitioners to have control over processes spawning across several DLTs.

In this report, we focus on the problem of managing cross-chain state in an integrated manner. First, we introduce the concept of cross-chain logic/cross-chain rules. After that, we present and discuss the results of our BI survey. Finally, we propose the BI evaluation framework, the first step to systematically evaluate BI solutions.
Protection against Failure of Machine Learning-based QoT Prediction
Authors: Guo Ningning , Li Longfei , Mukherjee Biswanath , Shen Gangxiang
Published: December 2021

Machine learning (ML)-based methods are widely
explored to predict the quality of transmission (QoT) of a
lightpath, which is expected to reduce optical signal to noise ratio
(OSNR) margin reserved for the lightpath and therefore improve
the spectrum efficiency of an optical network. However, many
studies conducting this prediction are often based on synthetic
datasets or datasets obtained from laboratory. As such, these
datasets may not be amply representative to cover the entire
status space of a real optical network, which is often exposed in
harsh environment. There are risks of failure when using these
ML-based QoT prediction models. It is necessary to develop a
mechanism that can guarantee the reliability of a lightpath service
even if the prediction models fail. For this, we propose to take
advantage of the conventional network protection techniques that
are popularly implemented in an optical network and reuse their
protection resources to also protect against such a type of failure.
Based on the two representative protection techniques, i.e., 1+1
dedicated path protection and shared backup path protection
(SBPP), the performance of the proposed protection mechanism is
evaluated by reserving different margins for the working and
protection lightpaths. For 1+1 path protection, we find that the
proposed mechanism can achieve a zero design-margin (D-margin)
for a working lightpath thereby significantly improving network
spectrum efficiency, while not scarifying the availability of
lightpath services. For SBPP, we find that an optimal D-margin
should be identified to balance the spectrum efficiency and service
availability, and although not significant, the proposed
mechanism can save an up to 0.5-dB D-margin for a working
lightpath, while guaranteeing the service availability.
Towards Optimal Parallelism-Aware Service Chaining and Embedding

Published: December 2021

Emerging 5G technologies can significantly reduce end-to-end service latency for applications requiring strict quality of service (QoS). With network function virtualization (NFV), to complete a client’s request from those applications, the client’s data can sequentially go through multiple service functions (SFs) for processing/analysis but introduce additional processing delay. To reduce the processing delay from the serially-running SFs, network function parallelism (NFP) that allows multiple SFs to run in parallel is introduced. In this work, we study how to apply NFP into the SF chaining and embedding process such that the latency, including processing and propagation delays, can be jointly minimized. We introduce a novel augmented graph to address the parallel relationship constraint among the required SFs. Considering parallel relationship constraints, we propose a novel problem called parallelism-aware service function chaining and embedding (PSFCE). For this problem, we propose a near-optimal maximum parallel block gain (MPBG) first optimization algorithm when computing resources at each physical node are enough to host the required SFs. When computing resources are limited, we propose a logarithm-approximate algorithm, called parallelism-aware SFs deployment (PSFD), to jointly optimize processing and propagation delays. We conduct extensive simulations on multiple network scenarios to evaluate the performances of our schemes. Accordingly, we find that (i) MPBG is near-optimal, (ii) the optimization of end-to-end service latency largely depends on the processing delay in small networks and is impacted more by the propagation delay in large networks, and (iii) PSFD outperforms the schemes directly extended from existing works regarding end-to-end latency.
Mutual impact of acoustic and linguistic representations for continuous emotion recognition in call-center conversations

Published: December 2021

The goal of our research is to automaticaly retrieve the satisfaction and the frustration in real-life call-center conversations.
This study focuses an industrial application in which the customer satisfaction is continuously tracked down to improve customer
services. To compensate the lack of large annotated emotional databases, we explore the use of pre-trained speech representations as
a form of transfer learning towards AlloSat corpus. Moreover, several studies have pointed out that emotion can be detected not only in
speech but also in facial trait, in biological response or in textual information. In the context of telephone conversations, we can break
down the audio information into acoustic and linguistic by using the speech signal and its transcription. Our experiments confirms the
large gain in performance obtained with the use of pre-trained features. Surprisingly, we found that the linguistic content is clearly the
major contributor for the prediction of satisfaction and best generalizes to unseen data. Our experiments conclude to the definitive
advantage of using CamemBERT representations, however the benefit of the fusion of acoustic and linguistic modalities is not as
obvious. With models learnt on individual annotations, we found that fusion approaches are more robust to the subjectivity of the
annotation task. This study also tackles the problem of performances variability and intends to estimate this variability from different
views: weights initialization, confidence intervals and annotation subjectivity. A deep analysis on the linguistic content investigates
interpretable factors able to explain the high contribution of the linguistic modality for this task.
Il dibattito come rischio educativo
Authors: Załęska Maria
Published: December 2021

«It is better to debate a question without settling it than to settle a question without debating it», says a quote from Joseph Joubert. Debate is one of the most valued text genres and is therefore included in curricular or extracurricular academic activities. What do we teach by teaching how to debate? What do students learn by learning how to debate? They can compete, collaborate and might even develop a new skill. Since concrete educational choices reflect a certain underlying educational philosophy, in what follows the model proposed by Biesta (2010,2016,2017) will be illustrated. The theoretical knowledge drawn from this framework will then be applied to the analysis of the Oxford Debate, in the version adopted by the regulated debate tournaments in Poland as well as to the discussion of a modification of the Oxford Debate itself, inspired by the concept of 'risk of education' (or rather, 'The Beautiful risk of educatio', as the title of one of Biesta’s books reads).
Improving Argumentative Skills in Education: Three Online Discussion Tools
Authors: van Laar Jan Albert
Published: December 2021

How can we foster sound argumentation and valid criticism in education? How to help students to avoid fallacies, resist polarization, respond wisely to misleading information, and how to make them produce arguments that are genuinely responsive to the position of those they address? I sketch a dialogical account of the nature of sound argument and criticism. Then, I discuss two types of argumentative dialogue: persuasion dialogue and negotiation dialogue. Finally, I explain how software applications provide an opportunity for students to analyse, evaluate and produce arguments, and to critically think about the design of discussion procedures. I also discuss a third software application that enables teachers and advanced students to themselves design online discussion procedures, so as to experiment with them and to advance their understanding of the advantages and disadvantages of various design choices. This paper support the idea that students’ argumentative skills will be enhanced by letting them engage in the online discussion procedures presented.
Puer bonus communicandi peritus. Esercizi e strumenti per dibattere tra pari
Authors: Simonetta Gianluca
Published: December 2021

The peer learning project RApP (Ragazze e Ragazzi apprendono tra Pari) took place at the ISIS Gobetti-Volta high school in Bagno a Ripoli, Florence. With the aim to develop debate and public speaking activities, the project applies the IDEAM method, known as the five canons of ancient rhetoric (Inventio, Dispositio, Elocutio, Actio and Memoria). Thanks to this framework, it is possible to visualize and apply changes to the organization and writing of an effective speech, as well as to its memorization and delivery in public. A platform of applied training combined with a set of propaedeutic exercises based on the approach of ancient progymnasmata outlines a gradual pathway aimed at strengthening the uses of language as an individual skill, with a view to acquiring the skills to use language in the social environment of debate.
La lingua delle petizioni nell’Egitto romano
Authors: Mascellari Roberto
Published: December 2021

This book investigates the linguistic and formal aspects of more than a thousand requests for justice and protection preserved in Egyptian papyri of the Roman Principate, mainly written in Greek. For many centuries in Egypt, from the Ptolemaic period to the late Roman Empire, petitions addressed to the judicial authorities shared the same textual structure and made use of recurring lexical formulas. Such uniformity was the result of the adherence by scribes and legal advisers to repertoires that had wide circulation. This study evaluates the correspondence between the formulas of the petitions and legislation, normative conventions, and spoken and literary language, and how these factors interacted with each other over the centuries.
Mentaliseren en hersenactivatie bij autisme
Authors: Nijhof Annebel
Published: December 2021

In recent years, there has been growing attention for the hypothesis that individuals with autism show difficulties in spontaneously representing others’ mental states, an ability referred to as spontaneous mentalizing. By testing adults with and without autism on a newly developed task, we found further evidence of differences in spontaneous mentalizing in autism, which could be linked to a decreased activation of the right temporo-parietal junction (rTPJ). The rTPJ appears to be crucial for mentalizing, and for social differences in autism. It is highly recommended to further test this in future studies.
