Authors: Gandhi Hemant , Tomar Amit , Singh Dimple
Published: May 2021

In this work, we investigated the invariance analysis of
fractional-order Hirota-Satsoma coupled Korteveg-de-Vries (HSC-KdV)
system of equations based on Riemann-Liouville (RL) derivatives. The Lie
Symmetry analysis is considered to obtain infinitesimal generators; we
reduced the system of coupled equations into nonlinear fractional
ordinary differential equations (FODEs) with the help of Erdelyi’s-Kober
(EK) fractional differential and integral operators. The reduced system
of FODEs solved by means of the power series technique with its
convergence. The conservation laws of the system constructed by
Noether’s theorem.

Given the emergence of SARS-CoV-2 virus as a life-threatening pandemic,
identification of immunodominant epitopes of the viral structural
proteins, particularly the nucleocapsid (NP) protein and receptor
binding domain (RBD) of spike protein, is important to determine targets
for immunotherapy and diagnosis. In this study, epitope screening was
performed using a panel of overlapping peptides spanning the entire
sequences of the RBD and NP proteins of SARS-CoV-2 in the sera from 66
COVID-19 patients and 23 healthy subjects by enzyme-linked immunosorbent
assay (ELISA). Also, three non-overlapping peptides belonging to the S2
domain of spike protein were assessed. Our results showed that while
reactivity of patients’ sera with reduced recombinant RBD protein was
significantly lower than the native form of RBD (p<0.001), no
significant differences were observed for reactivity of patients’ sera
with reduced and non-reduced NP protein. Pepscan analysis revealed weak
to moderate reactivity towards different RBD peptide pools, which was
more focused on peptides encompassing aa 181-223 of RBD. NP peptides,
however, displayed strong reactivity with a single peptide covering aa
151-170. These findings were confirmed by peptide depletion experiments
using both ELISA and Western blotting. Altogether, our data suggest the
involvement of mostly conformational disulfide bond-dependent
immunodominant epitopes in RBD-specific antibody response, while the IgG
response to NP is dominated by linear epitopes. Identification of
antigenic epitope in NP and RBD of SARS-CoV-2 could provide important
advances for the development of passive and active immunotherapy as well
as diagnostic tools for the control of COVID-19 infection.
Does Mandatory IFRS Adoption Affect Audit Hours and the Effectiveness to Constrain Earnings Management? Evidence from Italy
Authors: Azzali Stefano , Mazza Tatiana , Reichelt Kenneth J. , Wang Dechun
Published: May 2021

We examine the effect IFRS adoption has had on audit effort and the effectiveness of greater audit effort on constraining earnings management. We find that following Italy's adoption of IFRS, audit hours (but not the hourly rate) increased, suggesting that audit effort (in audit hours) increased following IFRS adoption. We then examine whether more audit hours are associated with improved audit quality in the IFRS regime. Consistent with prior literature (Caramanis and Lennox 2008), we find that more audit effort is associated with lower abnormal accruals in the period before IFRS adoption. Interestingly, after Italy adopted IFRS, abnormal accruals are lower, but audit hours were less associated with lower abnormal accruals, implying that more audit hours are needed to constrain earnings management. Collectively, our empirical analysis suggests that while audit effort increased with mandatory IFRS adoption, the effectiveness of audit effort to constrain earnings management decreased.

Published: May 2021

The Center for Accounting Education at Howard University partnered with public accounting firms, professional accounting associations, state CPA societies, and accounting academics to formulate recommendations to improve the advancement and retention of Black accounting professionals. Black accountants make up 9 percent of all U.S. accountants and auditors, but in public accounting firms they account for only 4 percent of professional staff and a mere 1 percent of partners (U.S. BLS 2019; AICPA 2019). An important indicator of the collaboration's success is that public accounting firm leaders sought out its findings and are implementing its recommendations. This paper presents the formation, operation, and outcomes of the collaboration. It also describes the value each group gained from collaborating and provides recommendations for managing collaborations. Our descriptions are offered as a model for others to translate the results of academic research into industry action.

Firm Use of Cybersecurity Risk Disclosures
Authors: Jiang Wanying , Legoria Joseph , Reichelt Kenneth J. , Walton Stephanie
Published: May 2021

Increasingly, firms are subject to rising cybersecurity risks. One way that firms can communicate cybersecurity uncertainty and reduce information asymmetry with external stakeholders is through cybersecurity risk disclosures. SEC (2011, 2018) guidance encourages the disclosure of significant cybersecurity risk factors. However, not all firms provide informative or quality disclosures following a cybersecurity breach event. In this study, we examine firms' use of cybersecurity risk disclosures after a cybersecurity breach. We find that not all breached firms alter their cybersecurity disclosure behavior similarly following a breach. Rather, firm prior breach experience and breach-related market reactions impact the provision of additional cybersecurity disclosures. Our study provides initial evidence on when firms provide additional cybersecurity disclosures post-breach and informs regulators and policymakers on how firms utilize cybersecurity risk disclosures as a response behavior.
Incentivizing Irreversible Investment
Authors: Livdan Dmitry , Nezlobin Alexander
Published: May 2021

Existing dynamic investment models that show that a manager can be incentivized to implement the optimal investment policy rely on the assumption that the firm is operating in an ever-expanding product market. This paper presents an analytically tractable, discrete-time, neoclassical model with irreversible investment and the possibility of unfavorable demand events. We show that even when the principal is uninformed about changes in demand for the firm's output, there exists a performance measurement system that leads to goal congruent investment incentives for the manager. If the principal can observe the unfavorable demand events, then goal congruence can be achieved using very simple accrual accounting rules, such as straight-line depreciation.

Sharia Marketing Mix: A Model of Digital Marketing Management Strategy of Zakat
Authors: Utami Pertiwi , Basrowi Basrowi
Published: May 2021

Zakat institutions make a variety of new innovations and accelerations in terms of management strategies to improve zakat management. Getting support from Government Regulations and DSN MUI Fatwa regarding the use of IT is certainly a motivation for zakat institutions to increasingly actively develop technology-based services. IT is one of the main focuses of the marketing strategy to increase muzaki's interest in distributing zakat through online zakat services. But in the middle of the community it seems that the presence of digital zakat services still requires a long process of obtaining 'postioning'. In addition, the use of technology must also be more careful, especially because of the negative impact it has. Sharia marketing mix offers strategy management based on sharia principles which in its development is dominated by contemporary fiqh studies. The research aims to provide a literature review on the collaboration of sharia marketing mix and digital marketing zakat. An interesting study considering there are still few studies that reveal a combination of both. Sharia marketing mix present offers management strategies that conventional marketing mix lacks. The results of the literature review state that sharia marketing mix has a special advantage in filtering the negative impact of the use of technology compared to the marketing mix which has been widely used by companies, financial institutions and non-banks.

Published: May 2021

The present paper covers the teaching and learning process of English language teaching in government schools of Andhra Pradesh. As the aim of the syllabus by the SCERT, Andhra Pradesh, the learners of English are expected to achieve proper communication skills to apply it in the global context. Bright and Marc Gregor (1978) have remarked that “there is no language learning without exposure” At this juncture mere knowledge of English, based upon listening, speaking, reading and writing directed towards acquisition of communication skills among high school students. The present study intended to find out the lacuna of secondary skills in English language among the students at high school level. An Oxford dictionary defines lacuna as ‘an absent part’. This paper portrays the percentage of expected and achieved skills of the students which is technically the term called as ‘Lacuna’. Most of the students are promoted to the next classes without adequate all the skills expected by the SCERT. Gradually the differences between expected and achieved skills have been increasing by the students year by year. At this juncture, it is very much needed to fill the lacuna between expected and achieved skills among the students for the strong foundation of the students in the field of communication skills.
Subverting the Myth of the Submissive Woman in Margaret Atwood’s The Penelopiad
Authors: Mathews Mulloor Alna Maria
Published: May 2021

‘The Penelopiad’ is a retelling of the Greek myth of Odysseus and his faithful wife, Penelope. According to the myth, Penelope cleverly keeps away from more than a hundred suitors when Odysseus went for the Trojan war. Therefore, her character is traditionally associated with marital fidelity and ‘The Odyssey’ portrays her as the quintessential faithful and submissive wife. This paper proposes to analyse how patriarchy creates the myth of the submissive woman and how Atwood subverts the myth through the characters of Penelope and her twelve maids.

A Pillage Story: The Wealth of Abdulhamid II
Authors: Keskinkılıç Erdoğan
Published: May 2021

Relying on primary documents from the Ottoman archives and relevant secondary sources, this article traces the destiny of late Ottoman sultan Abdulhamid II’s wealth in the aftermath of his removal from power in 1909. For centuries the Ottoman rules were never clear on the boundaries between the Ottoman dynasty’s and the state’s assets. The Ottoman dynasty ruled under a de facto understanding that all public lands and the state properties were of the property of sultan and his family. Without a challenge to this status quo, the sultans did not need to formalize this traditional idea. Legal ambiguity worked for the benefits of sultan but once sultans were side lined in the constitutional monarchy period, lack of legal coverage caused irreparable damages to deposed sultan and his heirs.
Book Review: Geraldine Heng, The Invention of Race in the European Middle Ages, UK/USA: Cambridge University Press, 2018.
Authors: Ferreira-Meyers Karen
Published: May 2021

Geraldine Heng delves into the sensitive topic of race with knowledge, experience and understanding. She divides her grand overview—507 pages on this “enormous and immensely complex” (p. 2) subject—of the invention of the concept of race in the European Middle Ages in seven chapters, all well documented and highly intriguing. Race has been and will remain a difficult, debatable and disturbing notion as it has a profound and pervasive impact on our daily interactions as human beings. While many of us celebrate diversity and embrace the idea of people being part of one human race, we cannot think away the concept of racial division. And so, it is important to question where it comes from, how it has evolved and where it will lead us. History, as my parents, who are both historians, would say is one of the ways—if not THE way—to understand contemporary issues, mindful too of the fact that “race is not as easily recognizable for those who inhabit a majority race” (p. 1). Heng takes us back to the European Middle Ages, to premodernity, in order to give us an insight on how certain stereotypes and misunderstandings started. It is not necessary here to remind us how much race and all its, mostly, negative aspects has had diverse and often scary consequences. We just have to think of the cruelties meted out to many Black, Asian and other ‘racial’ groups throughout the world.
CONTEMPORARY EUROSCEPTICISM AS A CHALLENGE TO EUROPEAN SOLIDARITY
Authors: Shibkova M. O.
Published: May 2021

The article analyses the influence of Eurosceptic sentiments on the level of solidarity among European Union member states. At the outset of the integration project construction the advantage of the Old Continent unification after being destroyed by the Second World War was apparent. However, with the European Union transformation and the emergence of new challenges, Eurosceptic voices are becoming louder and an increasing number of states start to question the efficiency of supranational institutions and choose to take measures on their own. The main trigger of the rise of Euroscepticism in the new millennium was the financial crisis with austerity measures and citizens' frustration with their low standard of living following. Without taking into consideration the results of the European Parliament Elections 2014, which proved the reinforcement of Eurosceptics, Brussels continued to further develop the integration process. However, with the lapse of time it became clear that Eurosceptics despite being deprived of the right to vote at the supranational level, can implement its potential to influence the EU through their activity within their countries. As a result of their actions the EU is faced up with two serious challenges: Brexit and inability to cope with the migration crisis by common effort. By giving certain examples of the reaction of member states' governments on the migration crisis and illustrating how these actions depend on the extent of Euroscepticism popularity in the countries the author shows that currently the level of European solidarity has become so low that it allows to speak about the transformation of the EU economic crisis into a truly political one.

Placed Upon the Landscape, Casting Shadows: Jewish Canadian Monuments and Other Forms of Memory
Authors: Ravvin Norman
Published: May 2021

This essay explores monuments, including the National Holocaust Monument in Ottawa, and gravestones in Jewish cemeteries in Montreal and Vancouver. Alongside these sites it considers how Canadian Jewish literature presents possibilities for Jewish history and language to mark the Canadian landscape though a consideration of Leonard Cohen and Eli Mandel. A discussion of Canadian monuments is relevant in light of recent demonstrations focused on removing statues and monuments from parks and government buildings. The essay contrasts community-inspired projects like Vancouver’s Holocaust memorial with Ottawa’s “National”monument, whose unveiling prompted a discussion about appropriate ways to represent history.Cet essai explore les monuments, y compris le monument national de l’Holocauste à Ottawa, et les pierres tombales des cimetières juifs de Montréal et de Vancouver. Parallèlement à ces sites, il examine comment la littérature juive canadienne, notamment les écrits de Leonard Cohen et Eli Mandel, offre des opportunités pour l’histoire et la langue juives de marquer le paysage canadien. Une discussion sur les monuments canadiens est pertinente à la lumière des récentes manifestations visant à retirer les statues et les monuments des parcs et des édifices gouvernementaux. L’essai met en contraste des projets d’inspiration communautaire comme le mémorial de l’Holocauste de Vancouver et le monument « national » d’Ottawa, dont le dévoilement a suscité une discussion sur les moyens appropriés de représenter l’histoire.
Economic and Financial Analysis of Cofiring the Coal Fired Steam Power Plant Capacity 660 MW with Biomass (
Authors: Wahyudi Widya Faisal , Garniwa M.K. Iwa
Published: May 2021

Research on Cofiring of the Existing Coal Fired Power Plant with biomass in the form of sawdust with a mixture percentage of 5% was carried out with the main objective of pursuing the acceleration of the renewable energy mix target of 23% (Green Booster) by 2025, with minimal CAPEX costs if compared to building new hydro or solar PV plants. At the initial stage of the activity, testing and analysis of the effect of cofiring will be carried out on several main parameters of the Existing PLTU's performance, as well as its reliability. In addition, it is also at the same time to get an overview and evaluate if the cofiring plan will be implemented through technical operational evaluations, the cost of production from the aspect of fuel costs (component C) and exhaust emissions to the environment. From the results of monitoring the operating load at around 635 MW (gross) using 5% cofiring, it can be seen that critical points such as main steam temperature, main steam pressure, gas economizer outlet temperature, mill outlet temperature do not show a significant increase, meaning they are still within the operating limits, reasonable and safe. From the calculation of the cost of fuel, the coal price is IDR 594 per kg, and sawdust price of IDR 472 per kg (on site) using the SFC difference of 0.0077 kg/kwh, and the CF assumption of 80%, then with an average annual electricity production of 4,415,040,000 kwh/year, fuel savings of around IDR 35.32 billion per year will be obtained. Exhaust gas emissions to the environment for SO2 and NOx still meet the environmental quality standard requirements according to the Minister of Environment and Forestry Regulation No.15 of 2019.

On the concept and signs of procedural misconduct
Authors: Lipinsky Dmitriy Anatol'evich , Popov Ivan Evgen'evich
Published: May 2021

The subject of this research is the conflictual social relations in the area of administration of justice, as well as the concept and signs of procedural misconduct. Analysis is conducted on the general signs of offense applicable to procedural misconduct. The author reveals the peculiarities of manifestation of signs of offense: wrongdoing, unlawfulness, fault, penalty. It is noted that public danger is characteristic to any offense, thus is attributed as a sign of procedural misconduct. The author underlines that there are no precise wording in the legislation, which does not allow carrying out accurate qualification of procedural offenses (for example, the term “contempt of court”). The conclusion is formulated that the procedural offense is a socially dangerous, faulty, and unlawful act, the commission of which implies procedural liability. It is substantiated that procedural misconduct has most universal (common to all types of offenses) signs. At the same time, the aforementioned signs are often difficult to determine, since the wording of the legislator is quite vague. The author recommends to include into the legislation the definition of procedural misconduct and its varieties, which would allow clearly differentiating the procedural misconduct from all other types of offences.
A Photoredox-Catalyzed Approach for Formal Hydride Abstraction to Enable Csp3–H Functionalization with Nucleophilic Partners

Published: May 2021

While a great number of C–H functionalization methods have been developed in recent years, new mechanistic paradigms to deconstruct such bonds have been comparatively rare. Amongst possible strategies for breaking a Csp3–H bond are deprotonation, oxidative addition with a metal catalyst, direct insertion via a nitrene intermediate, hydrogen atom transfer (HAT) with both organic and metal-based abstractors, and lastly, hydride abstraction. The latter is a relatively unexplored approach due to the unfavorable thermodynamics of such an event, and thus has not been developed as a general way to target both activated and unactivated Csp3–H bonds on hydrocarbon substrates. Herein, we report our successful efforts in establishing a catalytic C–H functionalization manifold for accessing an intermediate carbocation by formally abstracting hydride from unactivated Csp3–H bonds. The novel catalytic design relies on a stepwise strategy driven by visible light photoredox catalysis and is demonstrated in the context of a C–H fluorination employing nucleophilic fluorine sources. Difluorination of methylene groups is also demonstrated, and represents the first C–H difluorination with nucleophilic fluoride. Additionally, the formal hydride abstraction is shown to be amenable to several other classes of nucleophiles, allowing for the construction of C–C or C–heteroatom bonds.
Extrapolating DFT Towards the Complete Basis Set Limit: Lessons from the PBE Family of Functionals
Authors: Kraus Peter
Published: May 2021

In this work, I derive a set of formulas for calculating extrapolation parameters based on the percentage of HF exchange and PT correlation within the functional recipe. I use a set of CBS energies from finite element calculations, calculated with PBE and related functionals, to do so.

The obtained extrapolation parameters perform better than previous, empirically-derived values. They are shown to be transferrable to non-PBE functionals, and the [2,3]-zeta extrapolations work well in cases with non-covalent character.

Published: May 2021

The room-temperature activation of SF6, a potent greenhouse gas, is reported using a monovalent aluminium(I) reagent to form well-defined aluminium(III) fluoride and aluminium(III) sulfide products. New reactions have been developed to utilise the aluminium(III) fluoride and aluminium(III) sulfide as a nucleophilic source of F– and S2– for a range of electrophiles. The overall reaction sequence results in the net transfer of fluorine or sulfur atoms from an environmentally detrimental gas to useful organic products.
WhatsApp, comunicación móvil y participación política: un estudio cuantitativo en Ecuador
Authors:   Universidad Politécnica Salesiana, Ecuador, Zumárraga-Espinosa Marcos
Published: May 2021

Este trabajo explora la relación entre distintos usos políticos de WhatsApp y los comportamientos de participación política en el contexto ecuatoriano. Con el propósito de lograr un entendimiento más detallado, la participación política se clasificó en tres modos de acción específicos: offline convencional, offline protesta y online. Por su parte, el uso político de la aplicación se desagregó en tres tipos: (a) consumo de información política, (b) expresión y discusión política, y (c) contacto con grupos políticos online. A partir de los datos de encuestas aplicadas en el Distrito Metropolitano de Quito (Ecuador) en el 2018, los análisis de regresión múltiple desarrollados indican que el consumo de información política vía WhatsApp solo influye significativamente sobre las acciones de protesta política. Por el contrario, la expresión y la discusión política mediante esta aplicación móvil producen efectos movilizadores sobre todas las modalidades de participación analizadas. Efecto consistente que también se observa cuando WhatsApp se emplea para la interacción con grupos políticos online. En el apartado final se discuten los hallazgos del estudio tomando en cuenta la investigación previa en torno a los efectos democráticos de esta aplicación.

Este artículo propone un estudio de los sentidos producidos sobre aquello que se reconoce como gobierno abierto (GA), desde un enfoque comunicacional articulado con herramientas provenientes de la sociosemiótica. Nuestra hipótesis señala que no es posible investigar estas políticas aisladas del contexto sociourbano en el que se despliegan, configurando un tipo de ciudad y un sujeto para dicha ciudad. Nuestra estrategia teórico-metodológica se centra en abordar al GA como un dispositivo de regulación de la sensibilidad que funda nuevos modos de control social. El análisis se desarrollará sobre el caso de la ciudad de Córdoba, Argentina, cuya matriz urbano-poblacional y medio ideológico evaluante legitiman estas políticas de GA. Así, intentaremos, a partir de reconstruir el dispositivo de GA, comprender las líneas que lo conforman y que operan instaurando los horizontes políticos y de acción colectivos, creando un particular régimen de enunciación y visibilidad; estableciendo ciertas prácticas y relaciones posibles; y definiendo un específico tipo subjetivo. Este estudio se realizará sobre un corpus constituido por prácticas discursivas heterogéneas: notas periodísticas de medios locales, comunicaciones del gobierno municipal por canales oficiales y la propia plataforma de GA, el Portal de la Ciudad. El período de investigación comprende desde el inicio del sitio municipal, en el año 2016, hasta su relanzamiento en el 2018.
Uso e influencia de la analítica web en la producción de noticias: estudio de caso de un medio digital peruano
Authors:   Universidad Nacional Mayor de San Marcos, Barrenechea Arango Melissa
Published: May 2021

La era digital ha sumado un elemento clave en la producción de noticias: la analítica web, que permite comprender a la audiencia a través de una serie de indicadores y métricas. Esta investigación tiene como propósito describir el uso y la influencia de la analítica web en la producción noticiosa de editores y redactores de la web de RPP Noticias, principal radioemisora peruana. A partir de doce entrevistas en profundidad, se registran las percepciones y experiencias de periodistas respecto a esta herramienta de medición de audiencia. La investigación corroboró que la analítica web presenta un nivel de influencia en los contenidos seleccionados por los redactores y en la ubicación de notas en portada. Además, este hallazgo sugiere que los editores tienen miradas mixtas: los que tratan temas duros (política, administración pública, internacionales) defienden el criterio periodístico propio, mientras que los que abordan temas blandos (famosos, deportes y entretenimiento) apuntan a un balance entre su juicio y las preferencias de su audiencia.

Fotoactivismo, empatía y política de los afectos.
Authors: Allaltuni Zaira Sabrina , Contursi Ana
Published: May 2021

Esta entrevista se produce a partir del diálogo con SADO, colectivo fotográfico de la Ciudad de la Plata. La práctica y producción de este grupo de fotógrafes argentines da cuenta de los modos inéditos en los que la fotografía contemporánea se inscribe en la compleja realidad actual. A través de la constitución de prácticas que cruzan lo documental, lo poético, la horizontalidad, la autogestión, lo afectivo y lo social, sus producciones y acciones se instalan en la frontera entre el arte, el activismo y el fotoperiodismo. La decisión de enunciarse colectivamente en pos potenciar las voces, miradas y organización colaborativa  es una de sus apuestas más significativas.  El interés por los temas macro políticos convive con una fuerte inscripción en las problemáticas regionales, articulando las exigencias de la inmediatez, la calle y las historias de vida. Sus imágenes abordan desde diferentes perspectivas temas como trabajo, género, sexopolítica, territorio, memoria y ddhh, migración y agroecología, entre otros.
Archivo El Telégrafo: Prácticas pedagógicas y artísticas en la UArtes
Authors: Suarez Janina fernanda
Published: May 2021

Análisis del trabajo realizado por el colectivo de investigación Otras Derivas DIY en el fondo documental del periódico más antiguo del Ecuador. Durante el periodo 2018 - 2020, siguiendo una metodología de cadáver exquisito, el grupo dio valor a lo procesual en la búsqueda de una narrativa que promoviera la filosofía Do It Yourself entre la comunidad de la Universidad de las Artes. El Archivo El Telégrafo fue protagonista de prácticas pedagógicas a través de talleres abiertos guiados por artistas invitados donde se entrecruzaron fotografía, video, collage y dibujo. La trayectoria fue desde lo analógico hacia lo digital, arrancando con la estética fanzinera para llegar a la descontextualización de textos y fotografías, luego vino una mirada crítica y creativa de la visualidad para entender la saturación cotidiana de las imágenes y el (re)aparecer de lo que reposa en latencia. Como resultado del grupo está la exhibición Mapeando el Archivo.
Al otro lado del espejo
Authors: Meriguet Calle Pablo Raymond
Published: May 2021

El presente artículo pretende —mediante un ejercicio metodológico interdisciplinario entre la sociología del arte en la ciencia ficción cinematográfica y la filosofía— elaborar una reflexión crítica sobre los conceptos de ideología (Zizek) y fetichización (Lukács) gracias a la película The Animatrix (Wachowski et alt., 2003). El texto busca problematizar dichos conceptos gracias a la criticidad inmanente del discurso de la ciencia ficción en general y de la película aludida en particular.

Los argonautas del futuro
Authors: Novik Laura
Published: May 2021

El imaginario de un futuro espacial para el hombre en el actual contexto de pandemia emergió como un nuevo desafío para el diseño. El ejercicio implica unir territorios inmensamente distantes, jugando con puntos de vista que de­ben enfocar las urgencias del aquí y ahora en la Tierra, con la especulación que invita a levantar la mirada hacia el futuro de la humanidad en el Espacio. Son las nuevas fronteras que transita la disciplina desde finales del siglo pasado, a partir de la noción del diseño expandido con la que se interpretan escenarios de incertidumbre y complejidad. Anticipación, especulación y ficción, son especiali­dades recientes, que conectan al diseño con la ciencia, la tecnología y el arte, para interpretar aspectos formales, científicos, ambientales y sociales. Mediante un recorrido por distintos proyectos desarrollados en USA, Reino Unido y Argentina se analizan los modelos híbridos de diseño, los contextos y las historias que hacen parte de una narrativa universal sobre la supervivencia.
necesidad del otro en el cuento El antropófago de Pablo Palacio
Authors: Vinces Díaz Fernando
Published: May 2021

Esta investigación aborda la dicotomía civilización-barbarie como un discurso que se plasmó en el cuento El antropófago de Pablo Palacio gracias a las transformaciones e intromisión de la modernidad en el Ecuador de inicios del siglo XX. A través del análisis discursivo se develará el inconsciente del texto para dar respuesta a la siguiente interrogante: ¿es la exclusión una estrategia civilizatoria o también la practica la barbarie?
Best Practices to Address Inequities in Academic Support in the University Access Program
Authors: Sekonyela Lerato
Published: May 2021

Even though access to higher education (HE) has increased drastically among many institutions globally, some challenges persist, among which are impediments to student success. These challenges could potentially hinder students’ success and impede their smooth articulation to the preferred HE degree. Data were collected through focus group discussions that the Free-Attitude Interview technique facilitated. This study proposes potential strategies for implementing “best practices” to improve students' academic support in the University Access Program (UAP), particularly in the South African context. The proposed “best practices” are based on students who experienced challenges. Among these best practices are that students and tutors need to have regular meetings once or more per week, groups should not include more than fifteen first-year students, a student learning-centered approach should be employed, and students should be partners in the co-creation of the curricula and the co-evaluation of subject-related matters.
Estudio de terminologí­a especializada en los Documentos de Consentimiento Informado en el ámbito de las Investigaciones Cientí­ficas Biomédicas, en Chile
Authors: Ribeiro Alves Adriana , Ferreira Cabrera Anita
Published: May 2021

El estudio se circunscribe en la lí­nea de la terminologí­a especializadade acuerdo con la metodologí­a de la lingüística de corpus.El propósito principal fue contribuir desde una perspectiva fraseológica,con una propuesta de colocaciones para la caracterizaciónde los documentos de consentimiento informado utilizadosen las investigaciones cientí­ficas biomédicas. El enfoqueinvestigativo se sustenta en que este tipo de género discursivoconsidera entre sus elementos constituyentes, un término ouna unidad terminológica nuclear, de la especialidad misma. Sesostiene así­ que la identificación de las unidades fraseológicasespecializadas como las colocaciones, registran la tendencia dedemarcación de las estructuras tópicas en el documento de consentimientoinformado, presente en las informaciones y en lasdeclaraciones que anteceden a las firmas de los sujetos que estaráninvolucrados en una determinada investigación cientí­fica en las ciencias biomédicas. Los resultados se obtuvieron a través delprocesamiento computacional con Sketch Engine® de un corpusde documentos de consentimiento informado. De esta manera,se establecieron parámetros fraseológicos de concordancia y frecuenciade palabras en la configuración de un documento especializadoen el ámbito de las investigaciones cientí­fico-biomédicas.A partir de este estudio, se espera contribuir a estandarizaro normalizar el uso de documentos de información al sujeto deestudio/paciente, con una estructura adecuada que confieramayor legibilidad a dichos documentos, fundamentales para eldesarrollo de la investigación cientí­fica y, con implicancias parala interacción médico-paciente en el área de la salud.
í‘i pu tremen. Mis antepasados de Paula González Seguel: Repertorios de prácticas escénicas y diferencia cultural.
Authors: Henrí­quez Puentes Patricia , Ostria González Mauricio
Published: May 2021

Los lenguajes de la visualidad, la música, las danzas, los cantos, los textiles y sus iconografí­as, así­ como de la orfebrerí­a en plata que se encuentran tramados en la obra í‘i pu tremen. Mis antepasados de Paula González Seguel, hacen visibles, audibles y sensorialmente perceptibles la densidad de la diferencia cultural mapuche. Esta propuesta, representativa de la dramaturgia mapuche actual, pone énfasis en la cultura corporizada y en una diversidad de formas de conocimiento, almacenamiento y transmisión cultural, ampliando el canon y las fronteras disciplinarias. En la obra, un repertorio de prácticas escénicas y soportes mnemónicos irrumpen en el archivo para escenificar uno de los asuntos irresueltos más sentidos para el pueblo mapuche: su identidad territorial.
