A consensus solution for the taxation of the digital economy
Authors: Barata Marina
Published: October 2021

The taxation of the digital economy is not a new subject but its fast development demands a solid solution for this new way of doing business and generating profit and growth. The solution for this problem should be achieved at a global level, which has turned out to be a complex task. Therefore, the work we aim to do here is to identify and expose the path that has been followed by the international community (in general), and by the European Union, in particular, for the taxation of profits of companies with a significant digital presence and to what extent the lack of an unambiguous solution, within the Union, may condition its own objectives. But achieving a consensual solution comes with a bigger problem: is the unanimity rule established for tax policies, where decisions are taken by a special legislative procedure, suited for the European Union’s goal for a strong and dynamic single market, capable of competing with the world’s leading economies?
Critical success factors for electronic customer relationship management success adoption: Telecommunication companies case study
Authors:   Faculty of Information Science and Technology, Universiti Kebangsaan Malaysia, Bangi, Malaysia, et al. Anaam
Published: October 2021

A systematic literature review has been conducted on the exiting E-CRM system and found that 70% of E-CRM projects do not meet their ultimate goals. Furthermore, more than 77% of E-CRM projects do not succeed in the company's objectives. Many telecommunication companies reported that the existing E-CRM systems face severe challenges, which hinder the E-CRM system's successful adoption. This study aims to report the literature review on the Critical Success Factors for E-CRM systems and identify the rate of failure for E-CRM adoption. The systematic literature review (SLR) method has been conducted by analyzing 210 articles between 2011 to 2021 from different databases collections of research papers. The study determines E-CRM Critical Success Factors from three aspects: technology, organization, and individual factors. The three main categories were analyzed as the effects of the issue on E-CRM success in telecommunication companies. The results show that the three aspects (technology, organization, and individual factors) have a significant effect on the successful adoption of E-CRM.
Option pricing under the fractional stochastic volatility model
Authors: Han Yuecai , Li Zheng , Liu Chunyang
Published: October 2021

We investigate the European call option pricing problem under the fractional stochastic volatility model. The stochastic volatility model is driven by both fractional Brownian motion and standard Brownian motion. We obtain an analytical solution of the European option price via the Itô’s formula for fractional Brownian motion, Malliavin calculus, derivative replication and the fundamental solution method. Some numerical simulations are given to illustrate the impact of parameters on option prices, and the results of comparison with other models are presented.

Pricing timer options: second-order multiscale stochastic volatility asymptotics
Authors: Wang Xuhui , Wu Sheng-Jhih , Yue Xingye
Published: October 2021

We study the pricing of timer options in a class of stochastic volatility models, where the volatility is driven by two diffusions—one fast mean-reverting and the other slowly varying. Employing singular and regular perturbation techniques, full second-order asymptotics of the option price are established. In addition, we investigate an implied volatility in terms of effective maturity for the timer options, and derive its second-order expansion based on our pricing asymptotics. A numerical experiment shows that the price approximation formula has a high level of accuracy, and the implied volatility in terms of its effective maturity is illustrated.

Addressing Uncertainty: The Emergence of the CRMS/CFSPID Diagnostic Category Following Newborn Screening for Cystic Fibrosis
Authors:   Department of the History of Science, Harvard University, 1 Oxford Street, Science Center 371, Cambridge, MA 02138, USA, LaBonte Michelle Lynne
Published: October 2021

This article uses cystic fibrosis as a case study to examine how physicians and scientists have navigated uncertainty following newborn screening. Despite the many benefits of newborn screening, including earlier diagnosis, therapeutic intervention, and a reduced diagnostic odyssey, this public health approach also comes with challenges. For example, physicians began to document infants with indeterminate diagnoses - those with a positive screen who did not clearly fit into the cystic fibrosis or “normal” categories - by the early twenty first century. As a means of addressing this uncertainty and to facilitate long-term follow up of such infants, the U.S. Cystic Fibrosis Foundation recommended in 2009 that a new diagnostic term, CFTR-related metabolic syndrome (CRMS), be used. However, the CRMS label was not favored in Europe and a different term, cystic fibrosis screen positive, inconclusive diagnosis (CFSPID), was adopted in 2015 instead. Efforts to address the uncertainty associated with indeterminate diagnoses have been complicated, as stakeholders have held differing views about whether the screening algorithms should aim to maximize or minimize CRMS/CFSPID cases. Many who favor the identification of babies with CRMS/CFSPID note that they are at increased risk of developing symptoms and signs consistent with a cystic fibrosis diagnosis. In contrast, those who support algorithms that reduce CRMS/CFSPID cases point to iatrogenic harms associated with the medicalization of children who may remain healthy into adulthood. Furthermore, investigators have grappled with how best to ensure equity in newborn screening among different racialized groups while concomitantly attempting to minimize false positive results. These issues are applicable beyond the context of cystic fibrosis, especially as programs contemplate the incorporation or expanded use of next generation sequencing in algorithms for a wide range of diseases, and this history highlights how efforts to reduce uncertainty in one setting can lead to new and persistent sources of uncertainty in other areas.
If I Could But Choose Again, I Would Choose Wisely: A Psychoanalytic Approach To Mark Twain’s The Five Boons of Life
Authors: Mohammed Ali Baram
Published: October 2021

There are myriads of wants, wishes, and desires in the minds of human beings. However, the fulfillment of these needs is not always possible, for there are some internal and external factors governing the satisfaction of each desire. Before gratifying any needs and deciding whether or not to fulfill any request, it is crucial to examine the nature of this specific demand and consider the consequences that might eventually be brought about. The paper aims to represent the theme of repentance in The Five Boons of Life, which emerges from making wrong choices in life and the bitter consequences that follow. Further, it claims that Freud’s psychoanalytic theories can be applied to Mark Twain’s short story, The Five Boons of Life. The study is important as it may give some insights about where the regret comes from and how the human psyche works.

Authors: Tan Andy SL , Gazarian Priscilla K , Darwish Sabreen , Hanby Elaine , Farnham Bethany C , Koroma-Coker Faith A , Potter Jennifer , Ballout Suha
Published: October 2021

Background

Transgender and gender-expansive (TGE) adults are twice as likely to smoke cigarettes than cisgender individuals. There is a critical gap in research on effective and culturally sensitive approaches to reduce smoking prevalence among TGE adults.

Objective

This study aims to qualitatively examine the risk and protective factors of cigarette smoking among TGE adults through real-world exemplars.

Methods

We conducted a digital photovoice study among a purposeful sample of 47 TGE adults aged ≥18 years and currently smoking in the United States (March 2019-April 2020). Participants uploaded photos daily that depicted smoking risk and protective factors they experienced over 21 days on either private Facebook or Instagram groups. Next, we conducted separate focus group discussions to explore the experiences of these factors among a subset of participants from each group. We analyzed participants’ photos, captions, and focus group transcripts and generated themes associated with smoking risk and protective factors.

Results

We identified 6 major themes of risk and protective factors of smoking among TGE individuals: experience of stress, gender affirmation, health consciousness, social influences, routine behaviors, and environmental cues. We describe and illustrate each theme using exemplar photos and quotes.

Conclusions

The findings of this study will inform future community-engaged research to develop culturally tailored interventions to reduce smoking prevalence among TGE individuals.
Internet-Based Audiologist-Guided Cognitive Behavioral Therapy for Tinnitus: Randomized Controlled Trial
Authors: W Beukes Eldré , Andersson Gerhard , Fagelson Marc , Manchaiah Vinaya
Published: October 2021

Background

Tinnitus is a symptom that can be very distressing owing to hearing sounds not related to any external sound source. Managing tinnitus is notoriously difficult, and access to evidence-based care is limited. Cognitive behavioral therapy (CBT) is a tinnitus management strategy with the most evidence of effectiveness but is rarely offered to those distressed by tinnitus. The provision of internet-based CBT for tinnitus overcomes accessibility barriers; however, it is not currently readily available in the United States.

Objective

The aim of this study is to investigate the efficacy of internet-based CBT compared with that of weekly monitoring for the management of tinnitus in reducing tinnitus distress; reducing tinnitus-related comorbidities, including tinnitus cognitions, insomnia, anxiety, and depression; and assessing the stability of the intervention effects 2 months after the intervention.

Methods

A 2-arm randomized clinical trial comparing audiologist-guided internet-based CBT (n=79) to a weekly monitoring group (n=79) with a 2-month follow-up assessed the efficacy of internet-based CBT. Eligible participants included adults seeking help for tinnitus. Recruitment was conducted on the web using an open-access website. Participants were randomized via 1:1 allocation, but blinding was not possible. The study was undertaken by English or Spanish speakers on the web. The primary outcome was a change in tinnitus distress as measured using the Tinnitus Functional Index. Secondary outcome measures included anxiety, depression, insomnia, tinnitus cognition, hearing-related difficulties, and quality of life.

Results

Internet-based CBT led to a greater reduction in tinnitus distress (mean 36.57, SD 22) compared with that in weekly monitoring (mean 46.31, SD 20.63; effect size: Cohen d=0.46, 95% CI 0.14-0.77) using an intention-to-treat analysis. For the secondary outcomes, there was a greater reduction in negative tinnitus cognition and insomnia. The results remained stable over the 2-month follow-up period. No important adverse events were observed. Further, 16% (10/158) of participants withdrew, with low overall compliance rates for questionnaire completion of 72.3% (107/148) at T1, 61% (91/148) at T2, and 42% (62/148) at T3.

Conclusions

This study is the first to evaluate and indicate the efficacy of audiologist-delivered internet-based CBT in reducing tinnitus distress in a US population. It was also the first study to offer internet-based CBT in Spanish to accommodate the large Hispanic population in the United States. The results have been encouraging, and further work is indicated in view of making such an intervention applicable to a wider population. Further work is required to improve compliance and attract more Spanish speakers.

An Intervention With Michigan-Grown Wheat in Healthy Adult Humans to Determine Effect on Gut Microbiota: Protocol for a Crossover Trial (Preprint)
Authors: Kinney Gigi A , Haddad Eliot N , Garrow Linda S , Ng Perry K W , Comstock Sarah S
Published: October 2021

BACKGROUND

Daily fiber intake can increase the diversity of the human gut microbiota as well as the abundance of beneficial microbes and their metabolites. Whole-grain wheat is high in fiber.

OBJECTIVE

This manuscript presents a study protocol designed to understand the effects of different types of wheat on gastrointestinal tract microbes.

METHODS

Human adults will consume crackers made from three types of wheat flour (refined soft white wheat, whole-grain soft white wheat, and whole-grain soft red wheat). In this study, participants will alternate between crackers made from refined soft white wheat flour to those made from whole-grain soft white wheat and whole-grain soft red wheat flour. Survey and stool sample collection will occur after 7-day treatment periods. We will assess how wheat consumption affects gastrointestinal bacteria by sequencing the V4 region of 16S rRNA gene amplicons and the inflammatory state of participants’ intestines using enzyme-linked immunosorbent assays. The butyrate production capacity of the gut microbiota will be determined by targeted quantitative real-time polymerase chain reaction.

RESULTS

We will report the treatment effects on alpha and beta diversity of the microbiota and taxa-specific differences. Microbiota results will be analyzed using the vegan package in R. Butyrate production capacity and biomarkers of intestinal inflammation will be analyzed using parametric statistical methods such as analysis of variance or linear regression. We expect whole wheat intake to increase butyrate production capacity, bacterial alpha diversity, and abundance of bacterial taxa responsive to phenolic compounds. Soft red wheat is also expected to decrease the concentration of inflammatory biomarkers in the stool of participants.

CONCLUSIONS

This protocol describes the methods to be used in a study on the impact of wheat types on the human gastrointestinal microbiota and biomarkers of intestinal inflammation. The analysis of intestinal responses to the consumption of two types of whole wheat will expand our understanding of how specific foods affect health-associated outcomes.

A Guided Internet-Based Problem-Solving Intervention Delivered Through Smartphones for Secondary School Pupils During the COVID-19 Pandemic in India: Protocol for a Pilot Randomized Controlled Trial (Preprint)
Authors: Gonsalves Pattie P , Sharma Rhea , Hodgson Eleanor , Bhat Bhargav , Jambhale Abhijeet , Weiss Helen A , Fairburn Christopher G , Cavanagh Kate , Cuijpers Pim , Michelson Daniel , Patel Vikram
Published: October 2021

BACKGROUND

“POD Adventures” is a gamified mental health intervention delivered via a smartphone app and supported by counsellors for a target population of secondary school students in India. This paper describes the protocol for a pilot randomized controlled trial of a remotely delivered version of the intervention in the context of COVID-19 restrictions.

OBJECTIVE

Our objectives are to assess the feasibility of research procedures and intervention delivery and to generate preliminary estimates of the effectiveness of the intervention to inform the sample size calculation of a full-scale trial.

METHODS

We will conduct a parallel, 2-arm, individually randomized pilot controlled trial in 11 secondary schools in Goa, India. This pilot trial aims to recruit 70 participants with a felt need for psychological support. Participants will receive either the POD Adventures intervention delivered over 4 weeks or usual care comprising information about local mental health services and national helplines. Outcomes will be assessed at two timepoints: baseline and 6 weeks post randomization.

RESULTS

The first participant was enrolled on January 28, 2021, and 6-week assessment completed on April 4, 2021. Owing to a second wave of the COVID-19 pandemic in India, schools in Goa were closed on April 22, 2021. Trial participants are currently receiving the intervention or completing follow-up assessments.

CONCLUSIONS

This pilot trial will help understand the feasibility of implementing and evaluating a remotely delivered digital mental health intervention in a low-resource setting. Our findings will be used to design future trials that can address difficulties of accessing psychosocial support in-person and support wider efforts to scale up evidence-based mental health interventions for young people.

Open-source Web Portal for Managing Self-reported Data and Real-world Data Donation in Diabetes Research: Platform Feasibility Study (Preprint)
Authors: Cooper Drew , Ubben Tebbe , Knoll Christine , Ballhausen Hanne , O'Donnell Shane , Braune Katarina , Lewis Dana
Published: October 2021

BACKGROUND

People with diabetes and their support networks have developed open-source automated insulin delivery systems to help manage their diabetes therapy, as well as to improve their quality of life and glycemic outcomes. Under the hashtag #WeAreNotWaiting, a wealth of knowledge and real-world data have been generated by users of these systems but have been left largely untapped by research; opportunities for such multimodal studies remain open.

OBJECTIVE

We aimed to evaluate the feasibility of several aspects of open-source automated insulin delivery systems including challenges related to data management and security across multiple disparate web-based platforms and challenges related to implementing follow-up studies.

METHODS

We developed a mixed methods study to collect questionnaire responses and anonymized diabetes data donated by participants—which included adults and children with diabetes and their partners or caregivers recruited through multiple diabetes online communities. We managed both front-end participant interactions and back-end data management with our web portal (called the Gateway). Participant questionnaire data from electronic data capture (REDCap) and personal device data aggregation (Open Humans) platforms were pseudonymously and securely linked and stored within a custom-built database that used both open-source and commercial software. Participants were later given the option to include their health care providers in the study to validate their questionnaire responses; the database architecture was designed specifically with this kind of extensibility in mind.

RESULTS

Of 1052 visitors to the study landing page, 930 participated and completed at least one questionnaire. After the implementation of health care professional validation of self-reported clinical outcomes to the study, an additional 164 individuals visited the landing page, with 142 completing at least one questionnaire. Of the optional study elements, 7 participant–health care professional dyads participated in the survey, and 97 participants who completed the survey donated their anonymized medical device data.

CONCLUSIONS

The platform was accessible to participants while maintaining compliance with data regulations. The Gateway formalized a system of automated data matching between multiple data sets, which was a major benefit to researchers. Scalability of the platform was demonstrated with the later addition of self-reported data validation. This study demonstrated the feasibility of custom software solutions in addressing complex study designs. The Gateway portal code has been made available open-source and can be leveraged by other research groups.
Paraíso e infierno. La imagen de México en las literaturas y el cine europeo y estadounidense
Authors: Schmidt Friedhelm
Published: October 2021

En este ensayo, el autor hace una interpretación de México en algunos textos literarios y películas estadounidenses y europeos del siglo XX. Durante las primeras décadas de dicho siglo, México produjo una fascinación especial para muchos artistas e intelectuales. Esto fue el resultado del proceso de modernización e industrialización que hubo en Europa y Estados Unidos, proceso que significó una fragmentación de la vida cotidiana para el individuo manifestada como inseguridad personal. Además hay una serie de cambios políticos, que junto con los procesos antes mencionados se manifestaron como una crisis en la percepción del mundo. México se volvió el lugar preferido para las proyecciones y utopías (positivas y negativas) de los intelectuales europeos y estadounidenses.
Lo real-maravilloso y la tradición europea: La utopía como catalizador discursivo en los textos de Colón, Gaugin y Carpentier
Authors: Schuessler Michael
Published: October 2021

El autor en este ensayo se propone estudiar una faceta de la génesis literaria de lo real-maravilloso según fue concebido y desarrollado por Carpentier. Para comprender profundamente los orígenes de su proyecto literario es útil explorar la relación entre los periodos históricos del renacimiento y la edad moderna, íntimamente relacionados por la utilización del concepto o posibilidad de la utopía como un catalizador del discurso creativo. El «descubrimiento» de América por Cristóbal Colón en 1492 y el redescubrimiento de las culturas «primitivas» de Oceanía en 1891 por Paul Gauguin constituyen las dos manifestaciones culturales de estos periodos históricos que sustentan el enfoque de este estudio.
Refiguring the Self through the Other: The Spectacular Function of Mimicry in Shakespeare, Marivaux and Tieck
Authors: Kuprel Diane
Published: October 2021

Diane Kuprel does a review about the performance situation, dramatic figures engage in the ludic activity of mimicry by playing roles in the presence of other figures who function, passively or actively, as audience. To recast this in more ontologically weighted terms, the performance situation presents the process by which the subject (actor), in representing the self-as-other (character), submits to a self-dispossession, and expropriates and appropriates otherness as its own in its directedness toward others (audience). For this essay, she analyses three dramas: Troilus and Cressida by Shakespeare, L’île des esclaves by Marivaux and Die verkehrte welt by Tieck.
(Un)-Doing the Book «by the book:» Notes from the receiving end of Baz Luhrmann’s William Shakespeare’s Romeo + Juliet
Authors: Michel Modonessi Alfredo
Published: October 2021

Alfredo Michel Modonessi does an analysis about William Shakespeare’s Romeo + Juliet by Baz Luhrmann, as an example of the historical depletion of Shakespeare’s book by inviting conversation on the interaction of «book» and cinema within the conditions of reception in our frame-and-screen-wise post-modern world. Practically no reviewer he has read, or any colleague with whom he has discussed it, has failed to label Luhrmann's film postmodern.
Glifos antiguos y futuros. Algunas ekphrases mexicanas
Authors: Artigas Albarelli Irene M.
Published: October 2021

Al comenzar a escribir este trabajo, Irene M. Artigas elegió, buscando ekphrases, los poemas «Cabeza olmeca» y «Tulum» de José Emilio Pacheco y «Melismas para Gunther Gerzso» de Francisco Hernández. Si una ekphrasis es «the verbal representation of a visual representation», varios poemas sobre esas extraordinarias cabezas y sobre las pinturas de Gunther Gerzso eran claros ejemplos de este tipo de obras. Pero, ¿qué puede decirse al respecto de un poema sobre un grupo de edificios? Al comenzar a escribir pensó que había cometido un error: las obras arquitectónicas, según su «sentido común,» no podían considerarse «representaciones visuales.» La crítica ha incluido como ekphrasis a las representaciones verbales de pinturas, esculturas, fotografías, mapas, diagramas y películas pero nadie ha incluido edificios. ¿Son las obras arquitectónicas representaciones visuales?
Melville, Frege y Freud. Bartleby y los signos de la negación
Authors: Mier Raymundo
Published: October 2021

El drama de Melville nace de esta alianza entre un espacio que lo subyuga, los laberintos de una creencia que lo doblega sin tregua, y las exigencias exasperantes de la escritura. Tan sólo una vez surcó su propio espacio: Moby Dick. Este hombre arruinado, cuya escritura no ocultaba ya su destino equívoco, la desmesura de su impulso épico en colindancia con la derrota y el fracaso editorial, publicó en 1853, dos años después de terminado Moby Dick, un relato enigmático, incierto, indócil: fruto de un lenguaje capaz de hacer de la recreación del agobio una violencia que impone una distancia a la lectura; un enrarecimiento de la verosimilitud, una inflexión que alimenta el abismamiento alegórico de la narración.
Snakecharmers and Nascent Oxygen: André Breton and the American Marvelous
Authors: Winks Christopher
Published: October 2021

As André Breton and his fellow surrealists never tired of affirming, the transformative surrealizing impulse long antedated the surrealist moment (hence the movement's interest in developing and reconfiguring a force-field of multiple traditions or anti-canons). To some degree, surrealism's truth lay outside the movement proper, and a fortiori outside individual creative works, which while they could approximate certain dreams, obsessions, or lived moments, were but intimations of a greater revelation. Surrealism can best be described in terms of its constant search, articulated from Breton's 1924 Manifeste du surréalisme onward, for the marvelous, that gold of time that dwelled, no longer in the philosopher's stone, but in the unexpected turning points and encounters of daily life.
Portia as Primavera: Cultural Memory in The Death of the Heart
Authors: Farris Wendy B.
Published: October 2021

Near the end of the second part of Elizabeth Bowen's novel The Death of the Heart, the cad Eddie calls the ingenue Portia "Primavera." I wish to argue that in this moment Bowen appropriates Botticelli's painting, Primavera, as a subtext for her novel and with it the grace and charm of Renaissance Italy. The virtual presence of Botticelli's Primavera, or, if not the painting, the Renaissance mythological portrait its name suggests, is perhaps one of the continuities that rule Bowen's text, seen or unseen by her. In any case, even if my arguments for Botticelli's influence are not definitive, it is useful to explore the affinities between Bowen's text and Botticelli's painting. Bowen's visual subtext locates her and her readers between Renaissance houses and modern streets. It endows her social satire and psychological portraiture with latent layers of cultural memory, the kind of memory that Bowen values as a stay against the emotional brittleness and material chaos of modern life.
Imagen visual y semejanza: Williams y Heaney en torno a Brueghel
Authors: Artigas Albarelli Irene
Published: October 2021

La idea de este trabajo es analizar la manera en la cual el problema de la representación aparece en los poemas “Haymaking” y “The Corn Harvest” de William Carlos Williams (1962) y “The Seed Cutters” de Seamus Heaney (1975). Comencemos por dejar claro que en realidad se trata de ekphrasis de algunos cuadros del pintor flamenco Pieter Brueghel, “el Viejo.” Una ekphrasis es la representación verbal de una representación visual. El concepto, aunque parece sencillo, entraña problemas que se relacionan con la idea misma de representar, de volver a presentar, de hacer presente algo que es otra cosa. Si tenemos una representación verbal sobre otra representación, ahora visual, es de esperar que la primera siempre ponga en juego ciertos conceptos referentes al lenguaje, que compare su medio con el de lo que representa, que se cuestione la forma y la posibilidad de hacerlo.
Poemas prismáticos: Pessoa e Pessanha
Authors: Costa Horácio
Published: October 2021

Toda uma linhagem analítica, abstrativizante, todo um sentido de espaço brota com Cézanne, e ramifica como os seus pinheiros, um deles, uma imagem que viaja em mim desde a infância. Cézanne está para a “imaterialização” do olhar, do olhar que se desprende do tema, do objeto, da anedota, uma vertente perseguida de geração em geração na arte moderna. Na verdade, Cézanne talvez possa entrar para o contexto de formação da sensibilidade da arte moderna não apenas como o inventor desse novo olhar “imaterializador”, mas como o pintor que, num movimento de sentido contrário, primeiro procurou materializar, sem lançar mão a legendas ou narrativas de qualquer sorte, o invisível, e particularmente a luz até então funcional para a descrição volumétrica ou simbólica da representação pictórica, tornando-a visível, como problema de base para uma nova visualidade. Quando essa sensibilidade deveras nova adentra a escritura da poesia em português?
El descubrimiento científico: las dos caras de Jano
Authors: Zúñiga Villareal Noé
Published: October 2021

Jorge Volpi, con la novela En Busca de Klingsor. La trama gira alrededor del poder de la ciencia o, mejor dicho, el poder que ejercen los que manipulan la ciencia y el mal (visto como una causa de perjuicio para la humanidad). Obra ambientada en la Alemania de posguerra de la Segunda Guerra Mundial. Hablar del conocimiento y el poder que éste conlleva no es tarea fácil; sobre todo si se trata del conocimiento científico. El cambio que la ciencia ha operado a lo largo del siglo pasado ha sido espectacular: se puede afirmar que la mayor influencia de la ciencia y la tecnología sobre la vida cotidiana de los seres humanos, a lo largo de su estancia sobre la tierra, ha sido experimentada en el siglo XX. Volpi apuesta por un nuevo tipo de novela, abre una veta poco o nunca explorada por escritores de habla hispana. El progreso de la humanidad a través de la ciencia no parece que vaya a disminuir en el futuro próximo, por el contrario; de aquí que el individuo que se preocupe por su entorno deberá estar enterado acerca de los descubrimientos científicos y su impacto en la sociedad, pues de no hacerlo se corre el peligro de allanar el camino hacia un estado totalitario donde los poseedores del conocimiento serían grupos reducidos de poder.
La teoría elizondiana del antitiempo en Farabeuf o el tiempo visto desde el espejo
Authors: Gutiérrez Villavicencio Luis Andrés
Published: October 2021

La regresión del tiempo es uno de los temas predilectos de Elizondo. En diversos ensayos y cuentos experimenta las alternativas que ofrece esta posibilidad. El antitiempo de Farabeuf está en un universo inestable que oscila entre lo que es y lo que puede nunca haber sido. Lo constituyen apariencias que, sin embargo, adquieren por momentos más sustancia que los que habitan en ese otro mundo equívoco que se llama realidad.
Los conceptos de no-lugar y heteropatía en el análisis literario: Propuesta de relectura de Los autonautas de la cosmopista de Julio Cortázar
Authors: François Liesbeth
Published: October 2021

Muchas aproximaciones recientes a la literatura contemporánea se refieren a la teoría de los no-lugares del antropólogo francés Marc Augé, expuesta en su libro Non-lieux: Introduction à une anthropologie de la surmodernité (1992). Sin embargo, el concepto de ‘no-lugar’, por lo general, pierde parte de su potencial teórico al aplicarse de manera vaga y poco específica. Este artículo procura demostrar la productividad de un uso más consciente de la teoría de Augé y de la combinación del concepto de no-lugar con el de la heterotopía de Michel Foucault. Como piedra de toque propone analizar en Los autonautas de la cosmopista de Julio Cortázar (1983) la construcción de la imagen de la carretera como no-lugar heterotópico, así como en su progresiva desconstrucción. En su conjunto, el artículo ilustra la posibilidad de efectuar una lectura innovadora de los escritos del autor argentino mediante teorías actuales acerca del espacio y del lugar.
La mujer y la naturaleza en Terra baixa de Àngel Guimerà, en la ópera Tiefland de Eugen d’Albert y Rudolph Lothar y en el film Tiefland de Leni Riefenstahl
Authors: Soler Maridès
Published: October 2021

En este estudio se investiga la trasposición del drama rural catalán Terra baixa, de Àngel Guimerà, en la ópera verista y en la película del mismo nombre, ambas alemanas. Además de las peculiaridades inherentes a cada medio, se analiza en detalle el papel de la mujer y de la naturaleza (animales, montañas, agua, temporal) teniendo en cuenta las perspectivas y expectaciones de la sociedad de cada época ante esos temas, desde el estreno del drama en 1897 hasta el del film de 1953.
Sergio Pitol y Fabio Morábito: la autofiguración como decentramiento del autor
Authors: Salazar Jezreel
Published: October 2021

Este artículo reflexiona sobre la figura autoral en México a partir de dos escritores mexicanos que han elaborado, en los últimos años, obras de carácter autobiográfico: Sergio Pitol y Fabio Morábito. A partir de un análisis de El mago de Viena (2005) y El idioma materno (2014), se muestra cómo ambos autores ponen en duda las convenciones clásicas de la autobiografía y al mismo tiempo producen espacios textuales difíciles de clasificar, lo que contribuye a una noción disgregada de la identidad, una epistemología de la complejidad y una puesta en duda de las jerarquías autorales de la narración. Estas retóricas autobiográficas inestables (y las formas de figuración autocríticas que proyectan) implican representaciones diferenciadas del descentramiento del intelectual en el campo cultural mexicano, y contribuyen a modificar el estatuto jerárquico y narcisista del escritor.
El mundo es un libro que alguien escribe. O de cómo Elizondo vive y se escribe a sí mismo mediante un bucle paradojal
Authors: Gutiérrez Villavicencio Andrés
Published: October 2021

El tema central de la literatura de Salvador Elizondo es el proceso mismo de la escritura. El mundo es un libro que alguien, quizás él, está escribiendo. La imagen de autor que transmite en sus apariciones en radio, televisión e incluso en sus fotografías, es la de un personaje que vive la vida, en la medida de lo posible, como si fuera el personaje de una novela. Textos como su Autobiografía precoz, Elsinore y sus diarios son algunos ejemplos del proceso de autoficcionalización que hace el autor de su propia vida. Pero el culmen de este ejercicio se encuentra en El hipogeo secreto, donde Elizondo se escribe a sí mismo mediante un intrincado bucle paradojal de cuatro pasos, que analizo en este ensayo.
Entre el espejo, la máscara y la ausencia. Recorrido breve por la teoría de la autobiografía
Authors: Koestinger Gabriela
Published: October 2021

En tiempos recientes la escritura autobiográfica ha llegado a ocupar un lugar importante en la escena literaria; frente a esto, la teoría y la crítica han desarrollado una serie de herramientas conceptuales para dar sentido al fenómeno de las literaturas del yo. Este artículo presenta una revisión histórica de los principales conceptos que a partir del siglo XIX se desarrollaron en la teoría de la autobiografía. Se exploran las tres etapas propuestas por James Olney en la década de 1980; en primer lugar, la etapa del bios, compuesta por los trabajos de Wilhelm Dilthey y Georg Misch; en segundo lugar, se aborda la etapa del autos con los planteamientos de Georges Gusdorf y Philippe Lejeune; y finalmente se mira la etapa de la graphía o la ruptura postestructuralista con especial atención en el ensayo “Autobiografía como desfiguración” de Paul de Man.
Notas sobre la cocina de autor(a)
Authors: Flores Jurado Julieta

En 1969, en su conferencia “¿Qué es un autor?”, Michel Foucault señaló que la función autor no es “universal y constante”, sino que opera en un conjunto diverso y cambiante de discursos y prácticas. Si entendemos la autoría, siguiendo a Foucault, como un momento privilegiado de individuación, considero que es posible identificar una figura de autor emergente en la gastronomía, que se basa tanto en la definición del cocinero como una figura con autoridad y prestigio en el campo cultural y en la atribución de una firma de autor a su comida, como en la exclusión de sujetos a los que históricamente se les ha negado la posibilidad de ocupar un lugar de autor. A partir de cuestionar expresiones como “escritor gastronómico” y “cocina de autor”, reflexionaré sobre la construcción de la gastronomía como campo cultural, con un énfasis especial en la participación de las mujeres gastrónomas, y en las estrategias que han empleado para definirse como autoras en un sistema que tradicionalmente ha ignorado las expresiones del apetito y la creatividad femeninas.
The effect of carbon black on the curing and mechanical properties of natural rubber/ acrylonitrile- butadiene rubber composites
Authors: Boukfessa H. , Bezzazi B.
Published: October 2021

The present work investigates the effect of the amount of carbon black on curing and mechanical properties such as tensile strength, elongation at break, hardness and abrasion resistance of the natural rubber (NR)/ acrylonitrile-butadiene rubber (NBR) blend. For that purpose, a blend composed of 65% NR and 35% NBR filled with different content of carbon black N330 was used. The curing results indicate that the viscosity and the crosslink density of rubber composites increase and the scorch and curing times decrease with increasing the filler content. Mechanical properties such as tensile modulus and hardness of the CB filled NR/NBR blend were remarkably improved, indicating the inherent reinforcing potential of CB. Regarding tensile strength and abrasion resistance, they increase with the addition of carbon black, up to 50 phr. After that, these properties decrease slightly with filleraddition.

The space holder process (SHP) is a useful and common technique to obtain metal foams. However, an important question remains unsolved: Would the quality of the salt affect the properties of the aluminum foam obtained? In this paper, removable preforms of two types of salt (refined and unrefined) were infiltrated with A356 aluminum alloy to obtain metal foams with different pore sizes. The interaction preform-metal was studied from analyzing the morphological structure of the foams, the metal microstructure, and the corrosion resistance of the Al356 alloy. It was observed that, although the two types of salt exhibited some differences, they did not show variations in relation to the porous structure and metal microstructure in the aluminum foams obtained. Additionally, the electrochemical analyses did not show significant effects on the corrosion behavior of aluminum foams caused by the interaction with the salt preforms.
Real-time implementation of QFT, GA, and BFTPSO controller for pH neutralization system
Authors: Aparna V. , Jamal D.N.

The control of a pH process is complex because of severe nonlinearities in its behavior. A continuous pH neutralization process is usually represented as a first-order plus dead time system, but its gain varies for different operating points. Therefore, a conventional linear controller cannot be used, and the pH system was thus represented as a linear state-space model around an equilibrium point. This linear model was then used to compute the PID controller gains using robust and optimization techniques like quantitative feedback theory, bacterial foraging technique-based particle swarm optimization algorithm, and genetic algorithm. The corresponding controller gains resulting from the three algorithms were used to control the pH using a reconfigurable I/O device, NI myRIO-1900. Finally, the output time domain specifications and the servo and regulatory responses, resulting from the three algorithms, were compared in simulation and in real-time to deduce the appropriate tuning algorithm for this system.
Effect of Linearly Varying Heating Inside a Square Cavity under Natural Convection
Authors: KUMAR R AJITH , M Kunjunni
Published: October 2021

Telecommunication devices such as ADSL Modems or Wi-Fi routers are being widely used around the globe. Thermal management of such equipments are of critical importance as the increased power consumptions caused by technological upgrades results in increased heat generation within these systems. The heat transfer process inside such sealed and passively cooled equipments can be simplified as natural convection inside enclosures. Studying actual conditions inside electronic enclosure are necessary for their effective thermal management. This study aims at investigating the effect of non-isothermal heating inside such enclosures with linearly varying temperature distribution on free convection inside square enclosure. The issue of free convection of air interior of a square chamber with linearly varying temperature distributions on the left partition is studied numerically.  The effect of change of Rayleigh number, temperature distributions, on flow and temperature field and rate of transfer of heat are analysed. Rayleigh number is chosen to vary in between 103 and 106. Four different cases of linearly varying temperature distributions are considered. The outcomes are presented as stream line plot, isotherm contour and average Nusselt number. The outcomes depicted that case of linearly increasing temperature along the height gives higher Nusselt number than other cases.

Intervertebral disc (IVD) degeneration and the consequent low-back pain (LBP) affect over 80 % of people in western societies, constituting a tremendous socio-economic burden worldwide and largely impairing patients’ life quality. Extracellular matrix (ECM)-based scaffolds, derived from decellularised tissues, are being increasingly explored in regenerative medicine for tissue repair. Decellularisation plays an essential role for host cells and antigen removal, while maintaining native microenvironmental signals, including ECM structure, composition and mechanical properties, which are essential for driving tissue regeneration. With the lack of clinical solutions for IVD repair/regeneration, implantation of decellularised IVD tissues has been explored to halt and/or revert the degenerative cascade and the associated LBP symptoms. Over the last few years, several researchers have focused on the optimisation of IVD decellularisation methods, combining physical, chemical and enzymatic treatments, in order to successfully develop a cell-free matrix. Recellularisation of IVD-based scaffolds with different cell types has been attempted and numerous methods have been explored to address proper IVD regeneration. Herein, the advances in IVD decellularisation methods, sterilisation procedures, repopulation and biocompatibility tests are reviewed. Additionally, the importance of the donor profile for therapeutic success is also addressed. Finally, the perspectives and major hurdles for clinical use of the decellularised ECM-based biomaterials for IVD are discussed. The studies reviewed support the notion that tissue-engineering-based strategies resorting to decellularised IVD may represent a major advancement in the treatment of disc degeneration and consequent LBP.
