Competitiveness and technological innovation, fundamental theoretical elements for the internationalization of the Mexican Wine Industry
Authors: MOLINA-MARTÍNEZ Rubén , BALTAZAR-RAMOS Vianey
Published: August 2021

The objective of this research is to examine some of the theories of competitiveness and technological innovation that allow wine companies to develop internationalization strategies in the current framework of economic globalization. The implementation of these strategic decisions not only requires research efforts, but it also requires the participation of the collaborative network of the segments related to productive infrastructures. In Mexico, the wine sector presents a growth perspective due in part to the differentiation and expansion of the markets, but it also presents challenges of product offer, financing for the growth of the company and government policies such as the reduction of taxes that would allow the sector increase competitiveness. The methodology of this study is of an exploratory descriptive nature, since it aims to serve as theoretical support so that companies have the information that allows them to design the necessary internationalization strategies to have a dominant market share presence at the national and international level. The contribution of the qualitative analysis of this work lies in the dissemination of information on the subject, the debate of the concepts and the development of these competences; both at the business and academic level.
Una constelación de imágenes monstruosas: Arte contemporáneo y paisaje en la región del lago Nahuel Huapi
Authors:   , Gattás Vargas Maia
Published: August 2021

La tesis doctoral “Una constelación de imágenes monstruosas: Arte contemporáneo y paisaje en la región del lago Nahuel Huapi” consiste en pensar los impactos del arte contemporáneo en la construcción y representación del paisaje en la región Parque Nacional Nahuel Huapi. En nuestro tema hay varios campos que dialogan: el arte, la filosofía, la historia y la política. Buscamos trabajar desde un enfoque transdisciplinario, trazar puentes entre diversos campos, para abordar un caso concreto: la construcción que se realiza del paisaje de la norpatagonia argentina, por medio de las imágenes técnicas en el campo del arte actual. Es decir, abordaremos trabajos artísticos que están mediados por lo que Vílem Flusser denominó “cajas negras” (2015), las cámaras fotográficas, cinematográficas y de video, de las cuales desconocemos su interior. Esta investigación realiza un largo recorrido histórico, trazando una constelación de imágenes atravesadas por las herencias visuales del colonialismo europeo sobre este territorio. El recorrido que realizamos va desde el dibujo de los Patagones gigantes en el mapa de la exploración de Magallanes, hasta la figura mítica del Nahuelito, plesiosaurio que habita en el lago Nahuel Huapi. En este sentido, el concepto estético de lo monstruoso se nos aparece como una potencia para pensar como los paisajes coloniales pueden dar lugar a territorios decoloniales, que consideren a la monstruosidad como una positividad.
THE PORTRAYAL OF HEGEMONY AS SEEN IN SNOWPIERCER
Authors: Lasiana Dewi Saklina , Wedawati Mamik Tri
Published: August 2021

Snowpiercer is a sci-fi thriller movie directed by Bong Joon-ho. This movie presents the world’s survivors that live in a train creating their own economy and class system. The depiction of the movie is how power and ruling position could be achieved by conducting a process of moral and intellectual leadership rather than exercising full coercion. In Snowpiercer, Wilford as the dominant class attempts to gain power and authority to control the society through ideological indoctrination by the apparatuses. The study employs a sociological approach to literature to reveal the operation of hegemony in Snowpiercer. This study uses Antonio Gramsci’s concept of Hegemony as the main theory and Max Weber’s theory about power as supporting theory. In analyzing the data, this study uses a narrative and non-narrative approach. This study aims to describe hegemony through five stages of hegemony operation in Snowpiercer. Secondly, revealing the impact of hegemony on the subaltern class in Snowpiercer. Moreover, as the result shows that In Snowpiercer, hegemony is a process of gaining power through Indoctrinating ideology in which the role of coercive elements is necessary to maintain the power and authority obtained by the dominant class when the hegemony has weakened. This explains how hegemony conducted by Wilford lasts long and strong as it affects particular main aspects such as economic, military, education, culture, etc. Moreover, The dominant class's hegemony arises an impact on the subaltern class in the tail section, many people in the tail section get isolated, oppressed, and exploited.
THE CHANGING OF THE MAIN CHARACTER’S IDENTITY IN MOVIE JUST CHARLIE (2017)
Authors: Safinuriska Putri Miswa
Published: August 2021

Society constructs gender to distinguish the sexes of men and women. They believe that human is only born with two types male and female. Those are included in the term heteronormativity who have only two gender or sexual orientation options. Queer refers to people who have a gender identity or sexual orientation that differs from their biological gender. One of the terms Queer is Transgender which is a term for someone who needs recognition of gender identity from anatomical gender assigned at birth, or those who are considered ambiguous in their gender. Society finds it difficult to accept the existence of transgender because of the heteronormative. The experience of the story felt by transgender people is represented in the film Just Charlie (2017). This study aims to examine how gender identity is performed in the Just Charlie (2017) and how is the response of society. The theory used in this analysis is Judith Butler's "Queer" theory, specifically Butler’s gender performativity. This qualitative study has resulted in two findings. First, the main character showed the major terms of gender performativity such as an act of cross-dressing, repetition, and revelation. Second, although the United Kingdom is a liberal country, people still cannot be free to choose their gender preference. This study proved that gender performativity makes the identity of gender not only determined by the sexual genital from birth but also something act repeatedly.

Wireless sensor networks (WSN’s) comprise limited energy small sensor nodes having the ability to monitor the physical conditions and communicate information among the various nodes without requiring any physical medium. Over the last few years, with the rapid advancements in information technology, there has been an increasing interest of various organizations in making the use of wireless sensor networks (WSN’s). The sensor nodes in WSN having limited energy detects an event, collect data and forward this collected data to the base node, called sink node, for further processing and assessment. Few attributes of WSN’s like the energy consumption and lifetime can be impacted by the design and placement of the Sink node. Despite various useful characteristics WSN’s is being considered vulnerable and unprotected. There is a large class of various security attacks that may affect the performance of the system among which sinkhole an adversary attack puts dreadful threats to the security of such networks. Out of various attacks, a sinkhole attack is one of the detrimental types of attacks that brings a compromised node or fabricated node in the network which keeps trying to lures network traffic by advertising its wrong and fake routing update. Sinkhole attacks may have some other serious harmful impacts to exploit the network by launching few other attacks. Some of these attacks are forwarding attacks, selective acknowledge spoofing attacks, and they may drop or modify routing information too. It can also be used to send fake or false information to the base station. This study is analyzing the challenges with sinkhole attacks and exploring the existing available solutions by surveying comparatively which used to detect and mitigate sinkhole attacks in the wireless sensor network.

Authors: Junqueira Ana Helena
Published: August 2021

A cavidade oral faz parte do sistema gastrointestinal e, como tal, a presença de alterações nesta região pode ser o primeiro sinal de doenças sistémicas e gastrointestinais. Como essas alterações são muito comuns, principalmente em crianças, é importante que o dentista saiba quando elas são expressão de um quadro gastrointestinal. O objetivo desta revisão é fornecer ao dentista dados úteis para o diagnóstico, tratamento e manejo das condições mais comuns, como doença de Crohn, colite ulcerativa, doença do refluxo gastroesofágico e doença celíaca. Uma das alterações orais mais comuns é a erosão dentária, com perda de esmalte e aumento do risco de cárie dentária, que tem sido relatada em crianças e adolescentes com refluxo gastroesofágico. Hipoplasia do esmalte dentário e úlceras aftosas são mais comuns em crianças com doença celíaca do que na população em geral. Outra alteração oral muito comum é a gengivite, que afeta 9-95% das crianças na Europa e na América do Norte e mais de 60% dos adolescentes. Pioestomatite vegetante pode ser um sinal de colite ulcerosa e doença de Crohn, esta última também foi relacionada a edema difuso da mucosa, mucosa de paralelepípedo, muco-gengivite localizada, ulceração linear profunda, marcas de tecido fibroso, pólipos, nódulos e úlceras aftosas. O reconhecimento imediato de doenças sistêmicas e gastrointestinais por meio de um exame cuidadoso da cavidade oral pode ser o primeiro passo para novas investigações que podem levar a um diagnóstico precoce e tratamento oportuno.

Authors: Stohlmann Micah , Yang Yichen
Published: August 2021

Mathematical modeling has many possible benefits for students when implemented in K–12  mathematics instruction. When teachers have positive self-efficacy for mathematical modeling it is more likely they will continue to implement it. In order to measure teacher’s self-efficacy in the context of teaching mathematical modeling the development of an instrument specific to mathematical modeling is needed. The purpose of this study was to develop and validate the Teaching Mathematical Modeling Self-Efficacy Scale (TMMSS) as a tool for measuring perceived teacher preparedness for implementing mathematical modeling. The TMMSS was constructed through a thorough review of the literature regarding K–12 mathematical modeling and prior research on the development of teacher self-efficacy instruments. The participants for this study were from the USA. The TMMSS can be useful for evaluation of mathematical modeling professional development and school-based mathematical modeling research.
Redes produtivas de saber/poder: gênero e Matemáticas sob análise de estudantes
Authors: Neto Vanessa Franco , Borges Luiza , Alves Thays
Published: August 2021

O presente artigo traz alguns dos resultados de uma investigação cujo desenvolvimento da etapa inicial se deu com oito estudantes do nono ano do Ensino Fundamental e do primeiro ano do Ensino Médio, participantes de um curso preparatório para ingresso no Instituto Federal de Minas Gerais. Tal trabalho é parte do projeto de pesquisa intitulado “Onde aprendemos a viver o gênero? Nas aulas de matemática!”. Neste recorte, o objetivo foi compreender como estudantes da Educação Básica entendem, vivenciam e experienciam as questões de gênero no seu cotidiano (escolar, mas não só), especialmente em suas relações com a matemática enquanto ciência. Os resultados aqui apresentados são fruto de duas reuniões realizadas de forma virtual devido à pandemia da Covid-19. Buscando sustentação nas teorizações pós-coloniais, a questão “o que a matemática tem a ver com as questões de gênero?” abriu as reuniões e conduziu a seleção de materiais que tinham o papel de disparar as discussões, tais como notícias que circulam nas mídias, resultados de pesquisa apresentados em diversos relatórios que tratam da temática e vídeos institucionais que abordam os assuntos pertinentes ao desenvolvimento da investigação. Todo o trabalho de construção e tratamento dos dados foi realizado à luz da análise do discurso foucaultiana. Neste texto, serão apresentados dois enunciados, quais sejam: “a contribuição [invisível] de mulheres para o desenvolvimento da sociedade” e “mulheres não gostam de matemática”. Ambos os enunciados foram tratados a partir de uma compreensão de gênero como discursivamente produzido, num entendimento butleriano do termo e da matemática escolar como política cultural. Tal pesquisa, de cunho qualitativo, revelou que as performances de gênero são ainda marcadamente estereotipadas nas vivências dos estudantes, ao mesmo tempo em que há um processo ascendente de engajamento e questionamento dos espaços aos quais os corpos que performam o feminino podem, ou não, ocupar, espaços em que predomina o conhecimento matemático, por exemplo. Portanto, esses espaços são problematizados pelos estudantes participantes da pesquisa, esgarçando a fronteira entre os saberes.
Covid-19 Vaccine Benefits and Concerns: Nigerian Perspectives
Authors: Ayeotan Olorunfemi
Published: August 2021

The World Health Organization reported 162,184,263 cases of COVID-19 and about 3,364,446 deaths globally with Nigeria statistics at 165,709 reported cases and 2,066 deaths as of May 16 2021. This increase in reported cases and deaths globally can be drastically reduced when significant number of the population of the world becomes vaccinated. Researchers have developed different COVID-19 vaccines in a bid to control the morbidity and mortality rate as well as mitigate disease severity. Popular concerns about the vaccine in Nigeria and Africa ranges from effectiveness and side effects, poor understanding of the virus, lack of trust in the government, fear of the vaccine being used as a bioweapon designed by advanced countries to reduce the population of the poor ones by causing infertility, and lack of appropriate infrastructure for safe storage of the vaccine. Howbeit, the vaccine has been proven to be safe and effective. Nationwide delivery and acceptance will confer herd immunity and curb the menace of drug resistance.
Warming Acupuncture in the Treatment of Cervical Spondylotic Radiculopathy: A Systematic Review and Meta-analysis
Authors: Wang Zuqing , Li Yan
Published: August 2021

Background: Warming acupuncture (WA) is widely used in the management of Cervical spondylotic radiculopathy (CSR) in China and obtains desirable efficacy. Therefore, the aim of this study is to systematically assess the efficacy and safety whether using WA alone or combined with traditional
Chinese medicine (TCM) therapy for the treatment of CSR. Methods: PubMed, EMBASE, Sinomed, the Cochrane Library, CNKI, VIP and Wanfang databases were searched from their inception through 30 September 2020. All the retrieved records were screened or excluded based on the criteria that were
pre-established, and the results that meet the criteria were assessed by the Cochrane risk of bias tool and Meta-analysis was conducted by using RevMan5.3 software. Results: Fourteen RCTs (1021patients) were included in the meta-analysis. The effective rate of WA alone or combination with
TCM therapy was analyzed in comparison with the treatment of regular therapy. The results indicated that compared with regular therapy, WA alone or in combination with TCM therapy increased clinical effective rate (Odds ratio (OR)=4.43, 95% CI 2.85 to 6.90, P<0.01). Additionally decreased
VAS score (mean difference (MD)=-1.21, 95% CI -1.68 to -0.73, P<0.01), PPI (MD = -1.34, 95% CI -2.08 to -0.61) and PRI (MD = -0.55, 95% CI -0.72 to -0.37, P<0.001). However, adverse events of WA were not specially reported in all studies. Conclusions: WA as the main treatment for CSR
can improve the clinical effective rate and reduce the level of VAS score, PPI and PRI. Further research is needed to determine the effectiveness of WA for CSR treatment, rigorously and unambiguously.
Assessment Principles for the Mechanical Behavior of Clay Soils
Authors: Alamanis Nikolaos , Lokkas Philotheos , Chrysanidis Theodoros , Christodoulou Dimitrios , Paschalis Evangelos
Published: August 2021

The factors that determine the geotechnical behavior of soils are mainly their composition, the size of their grains and their moisture content. The design of a soil structure or foundation project must ensure the shear adequacy of the soil in all phases of construction and throughout the life of the project. However, the shear strength, in general, of the soil is not "constant" but depends on key external factors such as the prehistory of loads, the time and succession of load states, the overpressure of the pore water as well as other factors such as relative density, or any preload, the pressure field, the rate of change of the intensive state, etc. The influence of the deformations as well as the change of the intensive state during the sampling should not be ignored. Unlike other materials, in clay materials the determination of shear strength and its interpretation is a very complex problem. The aim of this article is to search for the mechanical behavior of clay soils (lignite, kaolinite, marl) as shown by the laboratory illustration related with the problems on shear strength of materials, based on the results of experimental research

Published: August 2021

The effects of the wall shear stress on an Electrical Submersible Pump (ESP) was investigated in this paper. A CFD model in ANSYS Fluent was proposed to simulate actual single-phase and two-phase flow. The bottom hole pressure was minimized by utilizing the artificial lift methods. The flowing fluids in pumps and pipes causes shear stress on surface interacting. In multiphase flow application pump damages on head degradation as well as shear stress affects. The K-ω turbulence model and the multiphase Mixture approach with the sliding technique used to solve the Navier-Stokes equation. To study the effects of gas-liquid (air-water) flow on the ESP and the pump handle ability, the rotation speeds were varied while the other parameters were kept constant. The rotation speeds simulated were at 500, 900, 1500, 2000 and 2500 rpm meanwhile the water flow rate and gas flow rate were kept constant with 20 L/min and 1% fraction, respectively. The results obtained show that as the rotation speeds were increased, the less concentration of the bubbles were observed, moreover the wall shear stress (WSS) increases. Although, the wall shear stress in both single-phase and two-phase flow were tend to increase as the blades length increased, however for the single-phase flow the WSS was found higher in all the simulated rotational speeds.
The Thyristor Switched Parallel Capacitors (TSPC) Converter for Power Factor Correction in Wind Power Systems
Authors: Kalpaktsoglou Dimitrios , Tsiakalos Anastasios , Roumeliotis Μanos
Published: August 2021

This paper presents a novel power factor correction circuit suitable for low-speed electric generators usually used in direct drive wind turbines. The Thyristor Switched Parallel Capacitors (TSPC) circuit belongs to the Controlled Series Capacitor (CSC) circuits. Those circuits have been used in power transmission lines to correct the power factor and improve the performance of the electrical system. Such a circuit can be used in wind power systems to improve and maximize the efficiency of a wind turbine. A typical direct-drive wind power system employs variable speed electric generators, but the downside is that systems like that suffer from high and variable inductive reactance. In order to correct the power factor and to improve the efficiency of the system, the inductive reactance of the generator must become equal in value to the capacitive reactance. A TSPC circuit uses a set of capacitors, connected in series with anti-parallel thyristors. In every cycle, a controller triggers the appropriate thyristors, allowing the current to pass from the capacitor which then provides the system with the capacitive reactance that matches the generator’s inductor reactance. Therefore, the TSPC circuit is able to counteract for any reactive losses and improve the power factor, as well as, the efficiency. This paper introduces this novel power factor correction circuit that employs capacitors in parallel configuration. This circuit was simulated in PSPICE and was implemented and tested in the lab. Based on the simulation and implementation results, we discuss the benefits as well as the drawbacks of the proposed circuit

Authors: Bouchareb Saoussan , Chiadmi Mohamed Salah , Ghaiti Fouzia
Published: August 2021

In our study we use the univariate and multivariate GARCH models to analyze the volatility behavior of the daily data of four Mediterranean stock markets (Morocco, Turkey, Spain, and France) spanning the period 2000-2020. We find a strong evidence of persisting of volatility in each of these markets. Results also indicate that both the univariate and the multivariate approaches capture well the ARCH and GARCH effects. We analyze the conditional covariances, and co-volatility spillovers between the Moroccan stock market and the three other Mediterranean stock markets. In order to study co-volatility spillovers, our work is built on the diagonal BEKK model especially the conditional covariances.

Published: August 2021

Complex fuzzy sets (CFS) generalize traditional fuzzy sets (FS) since the membership functions of CFS reduces to the membership functions of FS. FS values are always at [0, 1], unlike CFS which has values in the unit disk of C. This paper merges notion and concept in group theory and presents the notion of a complex fuzzy subgroup of a group. This proposed idea represents a more general and better optional mathematical tool as one of the approaches in the fuzzy group. However, this research defines the notion of complex fuzzy subgroupiod, complex fuzzy normal subgroup, and complex fuzzy left(right) ideal. Therefore, the lattice, homomorphic preimage, and image of complex fuzzy subgroupiod and ideal are introduced and studied its properties. Finally, complex fuzzy subgroups and their properties are presented and investigated
How Individual Experiential Fit Drives Mobile Platform Cocreation-supportive Behaviours in a Digital Business Ecosystem
Authors: Bui My-Trinh , Jeng Don Jyh-Fu , Le Thi Mai
Published: August 2021

Digital business ecosystems and platforms have emerged as collaborative tools, but few studies have investigated the competitive value that defines winners in the competition among platforms. This study examines the effects of experiential fit on identification, cocreation reward, and cocreation-supportive behaviours by considering the theories of organisational fluidity, service-dominant logic, and social support. Data collected from 1,090 respondents are analysed using AMOS and SPSS. The service-dominant approach is incorporated with a dynamic view of individual value fit to explore user identification, rewards, and cocreation value. The statistical results reveal that a mobile-based ecosystem may provide value convergence for its users (i.e., experiential fit) and thus enable value reservation (i.e., identification), achievement (i.e., cocreation reward), and value dissemination (i.e., cocreation-supportive behaviours). This study offers a new dynamic approach regarding cocreation-supportive behaviours for the digital business ecosystem literature

Practical Steps to Support and Empower Diversity in the Classroom
Authors: Grote Yoshi
Published: August 2021

The purpose of this paper is to present an argument that because the classroom is a micro-culture, teachers are in a unique position to create a classroom culture that realizes the progress which society is striving toward. For this reason, the English language classroom is an ideal place to challenge gender stereotypes and collectively deconstruct some aspects of the gender binary. The first section of the paper discusses why it is necessary to heighten awareness of gender issues in the classroom in terms of both inequalities and pressures for behavior. The second section outlines four practical steps teachers can take to support gender diversity in their learning communities. First, un-gendering pedagogical practices, the language taught and used, and the materials presented. Second, creating a safe, authentic and diversity-positive culture in the classroom. Third, increasing visible support for LGBTQ+ individuals. Finally, finding a way to model an authentic comfort with difference as a teacher.

教員はユニークな立場にある。何故なら教室はマイクロカルチャーであり、教員は自分たちの理想とする社会を教室文化に反映することができるからである。このような理由から、教室はジェンダー・ステレオタイプに挑戦し、議論するのに最適な場所だと考えられる。本稿の第一部では、ジェンダー問題に対する学生の意識を何故高める必要があるのかを論じる。第二部では、教室コミュニティにおいて多様性を支援するために教師がとることができる四つの実践的なステップを概説する。これらのステップとは、第一に、教材・使用言語・指導方法において性による偏見を無くす、第二に、教室内に安全で本格的かつ多様性を肯定する文化を作り上げる、第三に、LGBTQ+の人びとへの目に見える支援を増やす、そして最後に、教員として他者との違いを受け入れ、安心して本来の自分を出すモデルとなり、それを示す方法を見つける、というものである。
Active Participation in a Sci-Tech Community: Collaborative Peer Review
Authors: Armstrong Mathew , McCarthy Tanya
Published: August 2021

Active participation in learning is a central concept in many higher education institutions in Japan. For science and technology students in particular, learning approaches that promote collaboration, self-regulatory practices, and critical thinking in the L2, are especially encouraged in order to help prepare students for real-life research and/or professional situations. A collaborative learning initiative, iLearn, is introduced in this paper, which aims to help raise awareness of the qualities of good scientific writing and presentations by encouraging critical evaluation of authentic research through peer-review practices. Methodologically, the researchers examined peer-review exchanges of scientific posters and papers and then used content analysis to identify, categorize, and analyze meaningful exchanges. The authors concluded that it is worthwhile to implement collaborative programs that can help sci-tech learners to participate effectively in international and intercultural settings.

日本の多くの高等教育機関において、アクティブラーニングは中心的な概念となっている。とりわけ、科学技術（sci-tech）を専攻する学生にとって、実際の研究や就職後の状況に備えて、L2での協同作業、自己調整の実践、批判的思考を促進する学習アプローチは高く推奨されている。本研究では、査読行為を通して本格的な研究に批判的評価を行うことで、優れた科学的文章やプレゼンテーションの質に対する意識を高めることを目的とした、協同学習の取り組み（iLearn）を紹介する。研究方法としては、科学ポスターや論文の査読を内容分析によって考察し、有益なやり取りの分類を行った。本論は、sci-techの学習者が国際的・異文化的な環境に効果的に参加できるような協同学習プログラムを実施することは有意義であると結論づける。
Engagement, Task Evaluation, and Vocabulary Acquisition Through Extensive Listening
Authors: Suzuki Satoko
Published: August 2021

In extensive listening (EL) outside the classroom, students select listening materials based on their proficiency level and interests; however, studies of its effectiveness are scarce. This study explored engagement, task evaluation, and vocabulary acquisition through a one-semester EL intervention. Participants included 75 Japanese university students studying once a week for 15 weeks in a general English course and required to practice EL outside of class. The results showed that they engaged in EL for an average of one hour per week and had a relatively negative evaluation for EL. Nonetheless, the statistical analysis showed significant aural vocabulary improvement for all groups, with greater improvements seen among students with a lower initial vocabulary level. This study concludes that EL homework is effective, but adjustments are necessary to facilitate vocabulary learning.
多聴活動では学生が自らの英語力と興味にあった教材を選ぶが、その効果に関する研究は少ない。本研究では、１学期間の多聴への取り組み、多聴に対する評価、多聴後の語彙習得について調査した。参加者は週１回１５週間の一般英語クラスを受講する７５名の日本人大学生で、授業外で多聴に取り組んだ。その結果、彼らは平均週１時間の多聴に取り組んだが、彼らの多聴への評価は比較的否定的であった。一方、語彙テストスコアの向上は全てのグループで確認され、語彙力の低いグループのスコアが語彙力の高いグループより向上した。この研究結果から、授業外での多聴で語彙の学習効果はあったが、その効果をより高めるためには調整をする必要があると分かった。
Nietzsche, posmodernidad y verdad
Authors: Rojas Quispe Christopher Dante
Published: August 2021

La relevancia del presente trabajo recae en lo siguiente: la verdad es un concepto, sobre todo en el mundo actual, de plena vigencia y, ergo, pertinente. Su objetivo es esclarecer el concepto de verdad nietzscheano, basándonos en la obra Sobre verdad y mentira en sentido extramoral y en qué medida tal esclarecimiento fortalece el debate en torno a la posverdad. Se contrastaron las propias ideas del autor con la búsqueda emprendida por él desde una perspectiva posmoderna y fueron utilizadas como soporte las de Gilles Deleuze. Los hallazgos de la reflexión que plantea el trabajo son: consolidar una mirada flexible pero no por ello menos rigurosa respecto a la verdad y posverdad y fortalecer la idea de un Nietzsche cuya búsqueda fue perenne. La conclusión principal es: la verdad debe ser localizada constantemente en una conjunción pragmática con lo que es el mundo ahora

Objetivo. Evaluar las características clinicopatológicas del linfoma de células B grandes difuso, sin otra especificación (LCBGD, NOS), en una cohorte de pacientes peruanos. Métodos. Se estudiaron 72 casos con diagnóstico de LCBGD, NOS, en el INEN. Se evaluaron características clinicopatológicas, sobrevida global (SG) y otros parámetros clínicos de acuerdo con la célula de origen, la infección por  virus Epstein-Barr (EBER) y la expresión inmunohistoquímica (IHQ) de MYC y BCL2. Resultados. Hubo 54 % de mujeres y 46 % de hombres, con edad promedio de 65 años. El 76 % fueron ganglionares, la mayoría de ubicación cervical y el 24 % extraganglionares,  siendo el estómago el más afectado. Los estadios más frecuentes fueron II (35 %) y III (29 %), la mayoría con IPI medio-alto y alto.  Histológicamente, casi todos los casos tuvieron morfología centroblástica e inmunoblástica. Hubo proporción similar de casos con subtipos centro germinal (GCB) y no centro germinal (no-GCB). Los  GCB y EBER+ tuvieron mejor SG que los no-GCB y los EBER-, respectivamente. Asimismo, los casos con IHQ negativa para MYC y BCL2 tuvieron mejor SG y mayor porcentaje en estadios tempranos. Estos hallazgos no tuvieron significación estadística. Conclusión. Nuestros casos presentan características similares a lo descrito en la literatura, aunque con mayor porcentaje asociados al EBV y de casos no-GCB. El poco número de casos evaluados con IHQ para determinar subtipos y biomarcadores puede haber limitado el análisis estadístico en esta cohorte de casos.
