Energy system modelling can be used to assess the implications of different scenarios and support improved policymaking. However, access to data is often a barrier to energy system modelling, causing delays. Therefore, this article provides data that can be used to create a simple zero order energy system model for Thailand, which can act as a starting point for further model development and scenario analysis. The data are collected entirely from publicly available and accessible sources, including the websites and databases of international organizations, journal articles, and existing modelling studies. This means that the dataset can be easily updated based on the latest available information or more detailed and accurate local data. These data were also used to calibrate a simple energy system model using the Open Source Energy Modelling System (OSeMOSYS) and three stylized scenarios (Fossil Future, Least Cost and Net Zero by 2050) for 2020–2050. The assumptions used and results of these scenarios are presented in the appendix as an illustrative example of what can be done with these data. This simple model can be adapted and further developed by in-country analysts and academics, providing a platform for future work.
ECO-FRIENDLY MULTIVARIANT GREEN ANALYTICAL TECHNIQUE FOR THE ESTIMATION OF KETOCONAZOLE BY UV SPECTROSCOPY IN BULK AND CREAM FORMULATION
Authors: Kannaiah Kanaka , Sugumaran Abimanyu
Published: July 2021

The pharmaceutical industries are focusing on Green Analytical Chemistry principles like miniaturization, eco-friendly solvent usage, waste recycling, and analyst safety for sustainable results. A simple, eco-friendly sensitive and effective extraction and multivariant green analytical method to estimate ketoconazole in bulk and cream formulation were developed and validated according to International Council for Harmonisation (ICH) guidelines. Based on the multivariant analytical technique, the developed method built in linear regression equations between concentration and absorbance with seven different wavelengths. The validation results represent the method has linear at a concentration of 12.8-19.2 μg mL-1 with calculated Limit of Detection (LOD) and Limit of Quantification (LOQ) of 0.338 and 1.026 μg mL-1, respectively. The method results representing a precise accuracy, inter-day, and intraday precision in all the wavelengths with percentage Relative Standard Deviation (RSD) under the limits as less than 2. Also, the method was tested with two different marketed ketoconazole cream formulations with a satisfactory result. The results of the proposed method replicated the novelty in classic approaches and proved statistically. This method was confirmed as greenest than previous methods reported by using assessing tools like National Environmental Method Index (NEMI), Green Analytical Procedure Index (GAPI), Analytical eco-scale, and Analytical Greenness (AGREE) metrics. As a result, the proposed approach could widely utilize for an efficient green analytical methodology for the estimation of ketoconazole.

One of the most rapidly growing options in the management of cancer therapy is Targeted Alpha Therapy
(TAT) through which lethal α-emitting radionuclides conjugated to tumor-targeting vectors selectively deliver high
amount of radiation to cancer cells.225Ac, 212Bi, 211At, 213Bi, and 223Ra have been investigated by plenty of clinical trials
and preclinical researches for the treatment of smaller tumor burdens, micro-metastatic disease, and post-surgery residual
disease. In order to send maximum radiation to tumor cells while minimizing toxicity in normal cells, a high affinity
of targeting vectors to cancer tissue is essential. Besides that, the stable and specific complex between chelating
agent and α-emitters was found as a crucial parameter. The present review was planned to highlight recent achievements
about TAT-based targeting vectors and chelating agents and provide further insight for future researches.

Al-Quran recitation verification for memorization test using Siamese LSTM network
Authors: Rajagede Rian Adam , Hastuti Rochana Prih
Published: July 2021

In the process of verifying Al-Quran memorization, a person is usually asked to recite a verse without looking at the text. This process is generally done together with a partner to verify the reading. This paper proposes a model using Siamese LSTM Network to help users check their Al-Quran memorization alone. Siamese LSTM network will verify the recitation by matching the input with existing data for a read verse. This study evaluates two Siamese LSTM architectures, the Manhattan LSTM and the Siamese-Classifier. The Manhattan LSTM outputs a single numerical value that represents the similarity, while the Siamese-Classifier uses a binary classification approach. In this study, we compare Mel-Frequency Cepstral Coefficient (MFCC), Mel-Frequency Spectral Coefficient (MFSC), and delta features against model performance. We use the public dataset from Every Ayah website and provide the usage information for future comparison. Our best model, using MFCC with delta and Manhattan LSTM, produces an F1-score of 77.35%

Published: July 2021

Pineapple peel (Ananas comosus (L.) Merr.) has a potential natural-based anthelmintic agent. This study aimed to determine the effective concentration of pineapple peel juice against Paramphistomum sp. in vitro. Adults Paramphistomum sp. were divided into 5 test groups, the control group contained Albendazole 10% w/v, the nontreatment group contained NaCl 0.9% w/v and the treatment group contained pineapple peel juice with concentration of 12.5, 20, and 25% w/v. The number of live flukes and the motility scores were recorded every 15 minutes for 5 hours of incubation. The Survival Index (SI) and Relative Motility (RM) of flukes were calculated and statically analyzed using SPSS version 23 software. SI values of flukes in the 12.5, 20, and 25% w/v concentration of treatment group were 46.3, 50.0, and 38.9% respectively. RM values of flukes in the 12.5, 20 and 25% w/v concentration of treatment groups were 39.1, 42.0, and 34.1 respectively. RM values of flukes in the 12.5, 20 and 25% w/v concentration of treatment groups were 39.1359, 42.0249, and 34.1174 respectively. This research showed that, pineapple peel juice 25% w/v was effective against Paramphistomum sp. with survival index and relative motility values comparable to Albendazole 10% w/v (p <0.05).

Authors: Mestrom Eveline , Deneer Ruben , Bonomi Alberto G , Margarito Jenny , Gelissen Jos , Haakma Reinder , Korsten Hendrikus H M , Scharnhorst Volkher , Bouwman R Arthur
Published: July 2021

Background

Measurement of heart rate (HR) through an unobtrusive, wrist-worn optical HR monitor (OHRM) could enable earlier recognition of patient deterioration in low acuity settings and enable timely intervention.

Objective

The goal of this study was to assess the agreement between the HR extracted from the OHRM and the gold standard 5-lead electrocardiogram (ECG) connected to a patient monitor during surgery and in the recovery period.

Methods

In patients undergoing surgery requiring anesthesia, the HR reported by the patient monitor’s ECG module was recorded and stored simultaneously with the photopletysmography (PPG) from the OHRM attached to the patient’s wrist. The agreement between the HR reported by the patient’s monitor and the HR extracted from the OHRM’s PPG signal was assessed using Bland-Altman analysis during the surgical and recovery phase.

Results

A total of 271.8 hours of data in 99 patients was recorded simultaneously by the OHRM and patient monitor. The median coverage was 86% (IQR 65%-95%) and did not differ significantly between surgery and recovery (Wilcoxon paired difference test P=.17). Agreement analysis showed the limits of agreement (LoA) of the difference between the OHRM and the ECG HR were within the range of 5 beats per minute (bpm). The mean bias was –0.14 bpm (LoA between –3.08 bpm and 2.79 bpm) and –0.19% (LoA between –5 bpm to 5 bpm) for the PPG- measured HR compared to the ECG-measured HR during surgery; during recovery, it was –0.11 bpm (LoA between –2.79 bpm and 2.59 bpm) and –0.15% (LoA between –3.92% and 3.64%).

Conclusions

This study shows that an OHRM equipped with a PPG sensor can measure HR within the ECG reference standard of –5 bpm to 5 bpm or –10% to 10% in the perioperative setting when the PPG signal is of sufficient quality. This implies that an OHRM can be considered clinically acceptable for HR monitoring in low acuity hospitalized patients.
Predicting Unscheduled Emergency Department Return Visits Among Older Adults: Population-Based Retrospective Study (Preprint)
Authors: Chen Rai-Fu , Cheng Kuei-Chen , Lin Yu-Yin , Chang I-Chiu , Tsai Cheng-Han
Published: July 2021

BACKGROUND

Unscheduled emergency department return visits (EDRVs) are key indicators for monitoring the quality of emergency medical care. A high return rate implies that the medical services provided by the emergency department (ED) failed to achieve the expected results of accurate diagnosis and effective treatment. Older adults are more susceptible to diseases and comorbidities than younger adults, and they exhibit unique and complex clinical characteristics that increase the difficulty of clinical diagnosis and treatment. Older adults also use more emergency medical resources than people in other age groups. Many studies have reviewed the causes of EDRVs among general ED patients; however, few have focused on older adults, although this is the age group with the highest rate of EDRVs.

OBJECTIVE

This aim of this study is to establish a model for predicting unscheduled EDRVs within a 72-hour period among patients aged 65 years and older. In addition, we aim to investigate the effects of the influencing factors on their unscheduled EDRVs.

METHODS

We used stratified and randomized data from Taiwan’s National Health Insurance Research Database and applied data mining techniques to construct a prediction model consisting of patient, disease, hospital, and physician characteristics. Records of ED visits by patients aged 65 years and older from 1996 to 2010 in the National Health Insurance Research Database were selected, and the final sample size was 49,252 records.

RESULTS

The decision tree of the prediction model achieved an acceptable overall accuracy of 76.80%. Economic status, chronic illness, and length of stay in the ED were the top three variables influencing unscheduled EDRVs. Those who stayed in the ED overnight or longer on their first visit were less likely to return. This study confirms the results of prior studies, which found that economically underprivileged older adults with chronic illness and comorbidities were more likely to return to the ED.

CONCLUSIONS

Medical institutions can use our prediction model as a reference to improve medical management and clinical services by understanding the reasons for 72-hour unscheduled EDRVs in older adult patients. A possible solution is to create mechanisms that incorporate our prediction model and develop a support system with customized medical education for older patients and their family members before discharge. Meanwhile, a reasonably longer length of stay in the ED may help evaluate treatments and guide prognosis for older adult patients, and it may further reduce the rate of their unscheduled EDRVs.
The Effects of Quartic Term Mathematical Model on The Concentration Profile of Fixed Bed Gas Adsorber
Authors: Putri Ary Mauliva Hada
Published: July 2021

The need for a reliable mathematical model depicting the process inside a column adsorber has become a requisite in designing an effective gas adsorber. Even though this task can be done by using commercial software, it is still important to get an understanding of how the entire process happens.  In this paper, we discuss a new way to approximate the concentration profile inside the porous solids. It is an extension of the work of Liaw et al., who adopted a parabolic (i.e., quadratic) profile, which is a function of pellet radius while retaining the spherical symmetry. We extend their work by adding the quartic term. The inclusion of this new term still preserves the form of linear driving force approximation with some correction to Glueckauf’s parameter (i.e., the effective diffusivity coefficient). The addition of the correction will affect the breakthrough curve so that it affects the saturation time. In the binary system of hydrogen/methane discussed in this study, we found that a negative correction to the diffusivity coefficient will make the saturation happen earlier compared to that of the parabolic case, and vice versa. This study may help us design an efficient gas purifier, in particular when we set out for the regeneration of the adsorbent.Keywords: activated carbon; effective diffusivity coefficient; hydrogen; linear driving force; methane; parabolic profile A B S T R A KKebutuhan model matematis yang dapat menggambarkan proses penyerapan dalam kolom adsorpsi telah menjadi kebutuhan yang tak terelakkan dewasa ini. Walaupun kini telah tersedia berbagai perangkat lunak komersial, namun tidak dapat dipungkiri bahwa memahami bagaimana proses tersebut terjadi tetap menjadi suatu hal yang berguna. Paper ini bertujuan untuk menampilkan cara baru dalam pemodelan konsentrasi adsorbat di dalam adsorben padat berpori. Kami memperluas metode yang dikembangkan Liaw et al. dengan menambahkan suku pangkat empat (kuartik). Penambahan ini akan mengoreksi koefisien difusivitas efektif dari persamaan linear driving force (LDF). Koreksi yang bernilai negatif, misalnya, akan mengurangi nilai koefisien difusivitas tersebut sehingga akan menghambat kemampuan adsorpsi. Hasil perhitungan kami pada sistem biner hidrogen/ metana menunjukkan bahwa suatu koreksi bernilai negatif dapat menyebabkan saturasi berlangsung lebih cepat dari kasus profil parabolik. Begitu pula sebaliknya, koreksi positif akan menambah daya adsorpsi sehingga saturasi dapat diperlambat. Studi ini kami harapkan dapat diterapkan untuk mendesain suatu kolom adsorpsi yang efisien, terutama dalam perencanaan proses regenerasi adsorben.Kata kunci: hidrogen; karbon aktif; koefisien difusivitas efektif; linear driving force; metana; profil parabolik

The Research Financing Act. A New Framework for Publicly Funded Research in Austria and its Impact on Evaluation.
Authors: Pichler Rupert
Published: July 2021

On 7 July 2020, the National Council – the first chamber of the Austrian Parliament – passed a package of legislation introducing a new framework for the methods of allocating federal budgets to research, technology, and innovation (RTI). Its core is the Research Financing Act (RFA), complemented by several amendments to existing laws that are necessary for its implementation. Entry into force was on 25 July 2020, the amendments became effective as of 1 January 2021 (BGBl1. I No. 75/20202). The RFA is the biggest legislative project in the field of RTI policy since 2004 when the Research Funding Agency (FFG) was established (Pichler et al. 2007, pp. 329-336; Stampfer et al. 2010, pp. 775-776). For the first time, budget law regulations are now aligned with the needs of institutions performing or funding RTI (Pichler 2021). This article outlines the background and content of the RFA and concludes with a view on the significance of evaluation within the new system.

Authors: Samec Celeste , Yacobaccio Hugo
Published: July 2021

El objetivo de este trabajo consiste en estudiar y discutir las estrategias de explotación de camélidos sudamericanos empleadas por los ocupantes del sitio arqueológico Cueva Chayal (departamento de Susques, provincia de Jujuy, Argentina) durante el tramo final del Holoceno Tardío (entre 680 y 410 años AP). A fin de lograr dicho objetivo se revisará la información zooarqueológica recabada en el sitio y se presentarán valores de isótopos estables (d13CVPDB, d18OVPDB y d15NAIR) medidos sobre hidroxiapatita y colágeno óseo extraídos del material faunístico correspondiente a camélidos domésticos y silvestres. A partir de ello se discutirán las características particulares de las estrategias de pastoreo y caza empleadas por los ocupantes de la cueva y su relación con los cambios ambientales ocurridos en esta área durante el lapso temporal cubierto. En líneas generales, los resultados presentados aquí se muestran consistentes con lo esperado en función de la línea de base construida con datos isotópicos actuales del área, lo que permitió trazar ciertas continuidades en las estrategias de explotación de los camélidos –fundamentalmente el pastoreo– así como en las estrategias de movilidad y uso del espacio en este sector de la Puna Seca entre los siglos XIV y XV de la era.

Published: July 2021

El Campo Volcánico de Los Azufres alberga el segundo campo geotérmico más importante de México. La actividad volcánica en este campo inició hace aproximadamente 1.57 Ma y se mantuvo activa hasta < 26 ka, con la emisión de productos de composición muy variada. La actividad volcánica ha generado flujos y mesas de lava, domos y estratovolcanes, muchos de ellos con depósitos piroclásticos asociados. La composición química de los productos de todas estas rocas permitió agruparlas en cuatro diferentes unidades: Andesítico-Basáltica, Andesítica, Dacítica y Riolítica. Los productos riolíticos son los más abundantes, con edades que van desde 1.5 Ma a < 26 ka, mientras que las unidades máficas oscilan entre 1.5 a 0.33 Ma. La mineralogía de las diferentes unidades es acorde con su composición química, la Unidad Andesítico-Basáltica contiene ol+plg+opx+cpx y óxidos, la Unidad Andesítica contiene plg+opx+óxidos, la Unidad Dacítica contiene plg+opx+cpx+anf+bt y óxidos, así como trazas de cuarzo y circón, y la Unidad Riolítica contiene qz+sanidino+plg+bt+anf y óxidos. En general, las concentraciones de elementos mayores de las muestras analizadas de todas las unidades muestran características evolutivas claras que sugieren una relación genética, con un cambio en la tendencia definida por los datos químicos, aproximadamente a 64 % en peso de SiO2 para la mayoría de los elementos, lo que sugiere el fraccionamiento de fases minerales máficas. En cuanto a los elementos traza, se aprecian enriquecimientos en elementos incompatibles y tierras raras ligeras, con anomalías positivas pronunciadas en Pb, U y K y negativas en Nb, Ta y Ti, además de una variación en la anomalía negativa de Eu con la composición. De acuerdo con el modelo petrogenético generado en este trabajo, el mecanismo principal de evolución responsable de la diversidad magmática en el CVLA fue la asimilación-cristalización fraccionada (AFC) de rocas corticales, de composición similar a la de los intrusivos de La Huacana, con un coeficiente de masa asimilada/masa cristalizada de 0.5, un valor de cristalización de 54 %, asumiendo el fraccionamiento de 5 % de olivino, 15 % de ortopiroxeno, 10 % de plagioclasa y 5 % de feldespato potásico. En menor medida, la asimilación simple sin cristalización fraccionada, también tuvo un papel en la evolución de los magmas, sin embargo, el modelo no explica la generación de los magmas más riolíticos del área, para los cuales seguramente actuó otro mecanismo que no se aprecia en el modelo y por lo tanto no se discute en este trabajo.

Published: July 2021

Introducción: La enfermería es considerada una disciplina científica cuyo fundamento epistemológico está compuesto por conceptos del metaparadigma, patrones y visiones del conocimiento. El análisis de estos elementos a partir de situaciones específicas de la práctica permite la construcción de conocimiento disciplinar, el cual contribuye al mejoramiento de la práctica, dado que se refleja en el quehacer profesional y en la actitud que se asume frente a las situaciones de cuidado.

Objetivo: Analizar una narración de la práctica profesional de una enfermera en sala de hemodiálisis desde elementos epistemológicos propios de la disciplina de enfermería en el marco de la Teoría de Cuidado de Kristen Swanson.

Desarrollo: Se realizó una narrativa en enfermería a partir de una situación vivencial de una enfermera en una sala de hemodiálisis. Se analizaron los conceptos del metaparadigma disciplinar: persona, salud, cuidado y ambiente; los patrones personal, empírico, ético y estético del conocimiento y la visión en enfermería. La Teoría de Cuidados de Kristen Swanson con sus cinco procesos facilitó entender el significado de la situación y de la relación enfermera-paciente.

Conclusión: La narrativa resalta la importancia de continuar el proceso de construcción teórico científico de la disciplina de enfermería, posibilita la reflexión a partir de los elementos epistemológicos y debe ser considerada una metodología disponible para todos los profesionales. A su vez, permite afianzar el conocimiento e ir avanzando en el proceso de teorización para fundamentar con rigor científico el cuidado de la salud humana.

Introduction: Assisted suicide is considered an action in which a patient, wishes to terminate his/her life due to the pain and suffering caused by a disease and requests the necessary help from the healthcare professionals. The right to decide about ending one’s own life and the impact attributed to the experienced suffering are the main questions regarding assisted suicide.

Objective: Characterize the perceptions of nursing students about professional performance in the face of assisted suicide.

Methods: The research comprised a descriptive analysis with a qualitative approach, based on the application of semi-structured interviews on nursing students enrolled in the curricular 9th period, during 2014, in the city of Recife-PE, Brazil. The sample consisted of 19 students. The data, were analyzed and categorized using the Collective Subject Discourse (CSD) method.

Results and Discussion: The obtained data suggest that students consider assisted suicide as a way of preserving dignity in the face of procedures that will make the death an inevitably painful process. Indicate that euthanasia and assisted suicide should remain illegal, and they would not get involved professionally. But others assured their willingness to participate because they would be satisfying the patient's wishes, however, for its legalization it is necessary to create principles that would guide the execution of these procedures.

Conclusion: The students consider, that the professional can eliminate real possibilities of treatment and recovery of the patient by accepting his request for suicide. However, some students are in favor of this procedure, arguing that the patient is free to conduct his own life.

La odisea del conocimiento en los modelos de universidad. El caso de la Universidad Nacional y Popular de Buenos Aires (1973-1974)
Authors: Friedemann Sergio
Published: July 2021

El artículo aborda una reforma universitaria inconclusa, impulsada en la Universidad de Buenos Aires, Argentina, entre 1973 y 1974. Dado que entre los diferentes “modelos de universidad” abordados por la bibliografía especializada no existe alguno que se asemeje a la propuesta institucional analizada, la pregunta que guía el trabajo es si dicha reforma pudo haberse constituido en un “modelo” novedoso, teniendo en cuenta la pregunta por el sentido de la formación y la producción de conocimiento. El estudio sigue una estrategia cualitativa basada en el análisis de fuentes primarias orales y escritas.

Published: July 2021

Agriculture plays vital role in the economic of developing country. This paper Proposes, monitoring and access control system for greenhouse by using IOT. Our Proposed system will check for certain common conditions, for instance such as moistness, soil condition, temperature, humidity, light intensity, Carbon monoxide detection and operate the water supply through phone itself. All the environmental instance information are send to cloud server using Wi-Fi module ESP32. If any climatic condition crosses certain specific threshold limit related action will be taken place like if the temperature becomes high the rooftop of the green house will be opened or the exhaust fan will be switch ON manually by the user and if the light intensity goes down the external light supply will be given to the plants. The microcontroller will turn ON the motor if the moisture content of soil doesn’t meet the required condition. The sensors used in the proposed system are Resistive soil moisture sensor, DHT11 sensor, MQ9 sensor and LDR. The user can monitor and control parameters through mobile phone by using BLYNK app. This model was attempted in order to achieve the intelligent monitoring of greenhouse environment parameters like temperature, humidity, soil moisture etc., keeping the user continuously informed of the conditions inside the greenhouse using IOT technology.
Computer Assistive Palm Reader
Authors: Pathak Abhinav Kumar
Published: July 2021

Palmistry, also known as palm reading or hand prediction, is the study of a person's personality, fortune, and future by examining his or her hands. Chiromancy is another name for it. Palmistry encompasses not just the reading of one's hand or palm, but also the reading of one's arm, finger, and fingernail. This system shows a digital image processing application that can be used in palmistry to predict people's personalities or future lives. Based on edge detection and recognition, a palmistry prediction system has been created. This developed system uses morphological operations as well. The system uses a decision tree classifier algorithm to identify specific features in the input images and extract principal lines from a human palm image. The most important line patterns in palmistry are summarised and used as models for fortune-telling palm reading. The model predicts a person's personality and displays the predictions based on palmistry knowledge and date of birth.

Published: July 2021

A risk factor is anything that increases chances of getting a disease, such as cancer. Thus diagnosing the cancer at the earliest stage is very important. Nowadays any cancer affects the human and may lead to death and lung cancer is one of its kind.to decrease the mortality rate and give a good treatment for the affected ones we need a better technique to diagnosis the lung cancer in initial stage itself. Early prediction of Lung Cancer will help with the survival of cancer patients. Machine Learning and Deep Learning have been widely used in the diagnosis of Lung Cancer and on the early detection. The main aim of the research is to review the role of deep learning in Lung Cancer detection and diagnosis. So we have used the convolutional neural network (CNN) which is a class of deep neural network which presents lung cancer detection using Radiology Images.

O incremento de tecnologias e de inovações vem sendo umas das fontes de desenvolvimento econômico dos países ao longo das décadas. Diante da construção contextual da temática do agronegócio e sua importância, não só para o âmbito nacional, mas também para a localidade do vale do São Francisco, percebe-se a necessidade de trabalhos empíricos que preencham lacunas de compreensão prática desta temática. O presente estudo, objetiva identificar, através das percepções dos consumidores de vinho da região, os tipos de inovações que as vinícolas locais praticam. Para alcançar o objetivo foi feito uma pesquisa do tipo exploratória, com natureza descritiva e abordagem metodológica qualitativa e quantitativa utilizando da técnica de “análise de conteúdo”, com apoio da ferramenta Atlas T.I. para analisar os resultados. Sendo percebido que as viniculturas da região do Submédio do Vale do São Francisco acabam explorando o diferencial local, como clima em suas estratégias de marketing e esses discursos das vinícolas acabam sendo reproduzidos nas falas dos entrevistados desta pesquisa.
Uma literatura do corpo em Perto do coração selvagem
Authors: Nogarotto Pâmela , De Sales Cristiano
Published: July 2021

Este ensaio argumenta que o romance de estreia de Clarice Lispector, Perto do coração selvagem (1943), traz à tona uma literatura para ser experienciada com o corpo em seus vários níveis de criação, a saber, o corpo da personagem, Joana, o corpo do texto e o corpo do leitor. A noção de corpo que adotamos é a do filósofo francês Maurice Merleau-Ponty. A concepção de texto e de linguagem aproveitamos de ensaios de Roland Barthes. Sem reduzir a leitura do romance a mero pretexto para verificação de intuições teóricas, defendemos que importantes traços de toda a trajetória da autora já estão tensionados nesse primeiro livro, sendo o principal deles o reconhecimento de que o alcance artístico da linguagem está em seu aparente fracasso. Fazemos isso por meio de leitura apurada do referido romance.
Ser galinha. Ou: o estado de galinha, em Clarice Lispector
Authors: Andrade Pimentel Davi
Published: July 2021

Este artigo propõe apresentar a relevância da concepção de estado de galinha, formulada por nós, na construção textual da obra de Clarice Lispector. Visto, sobretudo, da perspectiva do alheamento do real, o estado de galinha está presente tanto nos textos em que o animal galinha é retratado, quanto nos textos em que os personagens humanos, em sua maioria femininos, optam por esse alheamento do mundo real, próprio do animal galinha, como atestam muitos dos narradores claricianos. Desse modo, podemos concluir que o estado de galinha se inscreve na obra de Lispector por duas vias: enquanto tema, como observamos, por exemplo, no conto “Amor”, presente em Laços de família; e enquanto efeito criador, como constatamos, por exemplo, na estrutura em formato de ovo do conto “O ovo e a galinha”, presente em A legião estrangeira. Dada a devida importância do tema para as questões do nosso presente, este artigo será dividido em dois momentos: no primeiro, pretendemos definir o conceito de estado de galinha e a sua reverberação textual a partir das ações dos personagens humanos; e, no segundo, discutiremos a diferença supostamente existente entre o olhar do animal e o olhar humano.
A Reading of Philip Roth’s Everyman as a Postmodern Parody
Authors: Jadwe Majeed U.
Published: July 2021

Philip Roth’s 2006 novel Everyman borrows its title from the famous fifteenth-century morality play The Summoning of Everyman. Yet, Roth establishes no clear or working connection between his novel and its medieval namesake. Roth scholars and critics have endeavored to identify intertextual continuities between these two works but with no tangible results. This article offers an alternative approach with which to view this problem by exploring the potential parodic nature of Roth’s text. More specifically, the paper theorizes that Roth fashioned a postmodernist brand of parody in his novel to negotiate the politics of representation of the issues of universality and determinism in the Medieval Everyman and the ideological discourses foregrounding their textual construction.
Mapping Spaces, Identities, and Ideologies in The Parisian (2019)
Authors: Rahman Fadwa Kamal Abdel
Published: July 2021

The Parisian (2019) is Isabella Hammad’s debut novel. It provides a dynamic spatial representation of a transitional era and a history that was unfolding and changing the face of the earth at the critical time between the two World Wars. Adopting the realistic tradition of nineteenth- century novelists, Isabella Hammad manages to provide a textual cartography of the places she dealt with in the Levantine and in France, mapping alongside the evolving sense of identity in the wake of drastic political, social, and cultural changes. By depicting those parallel worlds, the text dissects the Nabulsi society and reveals the heterogeneity that underlies its superficial homogeneity. It also introduces those spaces, specially Nablus, discursively bringing out their many facets through multifocalization. This paper aims at showing how the text underscores both the subjective experiential sense of place and the objective analytical and ideological sense of how place materializes the fabric of immanent relations of power. This is done through a geocritical approach that links together the literary representation with the lived spatial referent in ways that help readers understand a lot about the past and the present of this part of the world.
Analiza načina medijskog izvještavanja hrvatskih internetskih portala o koronavirusu
Authors: Benzinović Medina , Dabo Krešimir , Šimić Helena
Published: July 2021

Pojava epidemije koronavirusa promijenila je način na koji su mediji izvještavali svoje čitatelje u svijetu, pa tako i u Hrvatskoj. Bilo koja vijest se predstavljala kao glavna vijest pri čemu su se takvim sadržajima najviše isticali internetski portali. Intenzivno širenje informacija dovelo je do izrazito velikog broja senzacionalističkih naslova, ali i do dezinformacija u obliku tzv. lažnih vijesti. Cilj rada bio je utvrditi način medijskog izvještavanja o epidemiji u Hrvatskoj, ponuditi teorijski okvir vezan uz tu temu, ispitati percepciju i svjesnost čitatelja o fenomenu dezinformacija uz dodatnu analizu sadržaja najčitanijih medijskih portala.
