Authors: Mahfut Mahfut , Handayani Tundjung Tripeni , Wahyuningsih Sri , Sukimin Sukimin
Published: March 2021

Orchid is one of the most popular ornamental plants in the world. One of the orchid genera that is collected in a large number and known to have high morphological variations in the Liwa Botanical Garden is Dendrobium. However, to date, many Dendrobium collections have not been identified. Given the urgency of identification and the limitations of specimens in the field, especially flower organs, this study is important. This study aims to determine variations in morphological characters, phenetic relationships, and to identify Dendrobium collections based on leaf morphological characters in the Liwa Botanical Garden. Five accessions of Dendrobium were collected, namely CAT140, CAT 144, CAT 271, CAT 274, and IR015. Observation of 11 morphological characters leaves showed that leaf had high variations. The phenetic relationship based on the Gower similarity value and the UPGMA method shows that the Dendrobium in the Liwa Botanical Garden can be classified into 2 main groups formed with a similarity index value of 0.813. Based on Principle Component analysis values, it is known that the characters that have a large influence on grouping are the ratio of leaf length and width, leaf cross section, and leaf arrangement. The phenetic dendrogram topology is supported by the morphological character classification. The results of this study are expected to be basic information in the identification of natural orchids and conservation efforts in the Liwa Botanical Garden.

Authors: Kasma Utin
Published: March 2021

SMU Bina Utama Pontianak merupakan salah satu lembaga pendidikan formal swasta yang ada di kota Pontianak.  Dalam pengelolaan operasional sekolah, sebagian besar SMU Bina Utama sudah menerapkan sistem informasi. Namun sistem informasi yang digunakan belum memberikan pengaruh dalam pencapaian persaingan yang kompetitif secara optimal. Hal ini dikarenakan penerapan sistem informasi belum digunakan sebagai tools strategis melainkan hanya mendukung proses pengolahan data administrasi sekolah saja. Dikarenakan semakin bertambahnya SMU Negeri dan swasta yang baru dibuka, untuk itu SMU Bina Utama membutuhkan sebuah perencanaan strategis sistem informasi agar dapat bersaing secara kompetitif dengan SMU negeri maupun swasta yang ada di Pontianak. Framework yang digunakan dalam penelitian ini adalah framework Ward & Peppard. Framework Ward & Peppard dimulai dengan pemahaman situasi saat ini, yaitu lingkungan eksternal dan internal, baik pada lingkungan bisnis maupun pada lingkungan SI/TI. Adapun metode analisis yang digunakan adalah analisis Value Chain, Analisis SWOT, Analisis PEST dan McFarland Strategic Grid. Proses pengumpulan data dilakukan dengan wawancara dengan teknik wawancara personal (Personal interview), observasi dengan pendekatan observasi terstruktur dan studi dokumentasi. Tujuan dari penelitian ini adalah membuat perencanaan strategis sistem informasi pada SMA Bina Utama Pontianak untuk meningkatkan keunggulan kompetitif pada sekolah.

Published: March 2021

The photovoltaic system is used and utilized as electricity demand in many developed countries, including Indonesia. Nowadays, the photovoltaic system is an alternative source of inexpensive, reasonably priced electricity and easily applied in public facilities until laboratory usage. In Electrical Engineering Laboratory (EEL), Faculty of Engineering (FoE), Universitas Jenderal Achmad Yani is 1 kWp peak photovoltaic application available. The PV system is planned to be connected to the grid and produces 220VAC / 50Hz characteristics to meet the existing load capacity. The PV systems modeled include Pulse Width Modulation (PWM) controlled DC/DC Boost Converter, and DC/AC converter circuit. This study's experimental architecture is proposed to meet the electrical load following the characteristics of the photovoltaic device. The three types of electronic switching control, namely Metal Oxide Semiconductor Field Effect Transistor (MOSFET), Insulated Gate Bipolar Transistor (IGBT) and Gate Turn-off Thyristor (GTO), are used to achieve the highest performance. Based on the 1 kWp photovoltaic system's simulation results from the three types of electronic power switching, a minimum output voltage range of 210-230 VDC is produced. DC/AC Converter testing has been carried out and can be tested on a grid-connected 220VAC/50Hz single phase with the highest output using MOSFET equal to 96.7%.

COMMENTAIRE COMPOSÉ: LEITURA EXISTENCIALISTA DE UM EXCERTO DA PROSA DE FICÇÃO CLARICIANA
Authors: Menezes Hugo Lenes
Published: March 2021

Escritora de costumes, dos altos e baixos existenciais de seres nada épicos num cotidiano indistinto, Clarice Lispector é uma aguda perscrutadora da psique ou alma humana. Então, no trabalho ora apresentado, resultante de sugestão de pesquisa à professora de Filosofia e de Letras Jeanne Marie Gagnebin de Bons, na Universidade Estadual de Campinas (UNICAMP), para a nossa monografia da disciplina Crítica I (1995), entre os métodos e técnicas da crítica literária, optamos pelo Commentaire Composé, método francês através do qual analisamos, do primeiro romance de Clarice Lispector, qual seja, Perto do coração selvagem (1943), um excerto, como exata ilustração do pensamento do filósofo existencialista Jean-Paul Sartre, especialmente no tocante à liberdade. Isso porque o citado romance narra a trajetória existencial de Joana, uma órfã de mãe que, desde tenra idade, manifesta forte individualidade em conflito com a família e a sociedade, por entender que, consciente de uma provável consequência repressora, ela pode tudo.
CONCEPÇÕES DE LINGUAGEM E DE LEITURA NO ENEM DE LÍNGUA INGLESA
Authors: Petry Radünz Amanda , Marcuzzo Patrícia
Published: March 2021

No Brasil, o Exame Nacional do Ensino Médio (ENEM) exerce influências nos contextos de ensino por ser utilizado como critério de acesso a importantes universidades públicas e privadas e como critério de participação em projetos sociais que viabilizam esse acesso. As influências que o ENEM exerce nos contextos de ensino inclui as concepções teóricas que o subjazem, visto que as questões que compõem o exame são fundamentadas em teorias que, consequentemente, estão presentes na escola. O objetivo deste trabalho é analisar as concepções de linguagem e de leitura que subjazem as questões do ENEM de Língua Inglesa (ENEM-LI). Para tanto, foram consideradas, principalmente, as concepções de linguagem como meio de interação e como instrumento de comunicação; e as concepções de leitura como produção de sentido e como decodificação. Foi analisado um total de 40 questões de LI de oito edições do exame, com ênfase na análise semântica dos enunciados das questões. Os resultados apontam que ambas as concepções de linguagem e de leitura subjazem diferentes questões do exame, o que pode indicar um direcionamento para visões mais atuais de linguagem como gênero e de leitura como letramento, privilegiadas em documentos oficiais que orientam o ensino de línguas no país.
O RACISMO, ANTIRRACISMO E BRANQUITUDE: OS SIGNOS E O TEMA EM RESSONÂNCIA DIALÓGICA NO EMBATE IDEOLÓGICO
Authors: Ramos dos Santos Camilla , Mendes da Rocha Marlúcia , Francisco de Carvalho Isaias
Published: March 2021

“Nega maluca”, “preto safado”, “beiçola” e “cabelo de Bombril” são alguns dos xingamentos dirigidos a pessoas negras. O racismo estrutura e institui o ordenamento das relações étnico-raciais mediante o tema ideológico da branquitude, a partir do contexto colonial até os presentes dias. As ideologias em torno da racialização reverberam sentido como práticas reproduzidas nas condições das relações de produção cultural e impactam de diferentes formas o sistema político que, a priori, exclui afrodescendentes dos espaços de poder e acesso a direitos básicos. Os pares antitéticos na luta inscrita na linguagem em torno do significante “raça” representam discursos disseminados pela transição de uma dinâmica dialética, cuja materialidade interfere também na consciência e no ato de fala de cada indivíduo.
CLARICE LISPECTOR PARA MULHERES – E HOMENS – DO SÉCULO XXI
Authors: Amodeo Maria Tereza , Da Silveira Andresa
Published: March 2021

Conhecida por transitar pela narrativa - do romance à crônica, do conto à literatura infantil, sem falar nos artigos de jornal -, Clarice Lispector foi lida e relida em cerca de trinta idiomas e hoje se tornou popular na internet por meio de frases soltas de sua autoria ou não, mas geralmente  descontextualizadas ou até transfiguradas. Acredita-se, entretanto, que as personagens femininas que a autora criou há cerca de sessenta anos, em Laços de família, ainda repercutem no século XXI. Este artigo pretende sinalizar a atualidade de seu texto e a possibilidade de renovadas leituras, por meio da análise das personagens femininas de alguns contos da obra referida. Para tanto, recuperam-se brevemente alguns aspectos da trajetória literária da autora, problematizando sua rejeição à vinculação a pautas ideológicas. Críticos literários como Regina Zilberman, Benedito Nunes, Nadia Gotlib, Yudith Rosenbaum e Benjamin Moser orientam essa reflexão. Ao relacionar as personagens de Clarice à contemporaneidade, dados de realidade em relação à posição da mulher nos dias de hoje são pontuados e analisados, tendo como apoio para as questões de gênero e feminismo contribuições de Simone de Beuavoir, Heloisa Buarque de Holanda, Marcia Tiburi e Bell Hooks. Os contos em questão constroem universos ficcionais autônomos, de forte sentido imaginativo, que permitem uma análise crítica da sociedade, promovendo o exercício da alteridade.

Em 1999, Teresa Cristina Montero Ferreira publica Eu sou uma pergunta: uma biografia de Clarice Lispector, resultado de anos de leitura apaixonada e uma pesquisa percuciente em torno dessa figura visceral chamada Clarice Lispector. Aqui, muito gentil e prontamente, Teresa nos concede a singular oportunidade de conhecer um pouco mais sobre o gesto criador dessa biografia, bem como lança luz sobre “aquele ser inalcançável, ou assim vivido em sua fantasia, responsável pelo seu prazer ou sua inquietação, aquele ser cuja presença na obra é, ao mesmo tempo, total e nula, aquele ser imaginário, ficção do leitor – o escritor”, como afirma a autora na introdução de sua obra.
O ENSINO DE LÍNGUAS POR UMA ABORDAGEM COMPLEXA EM TEMPOS DE PANDEMIA: QUEBRANDO PARADIGMAS
Authors: Cruz Suzana Longo da , Lima Diógenes Cândido de , Santana Cremilton de Souza
Published: March 2021

Os desafios desencadeados pela pandemia da covid-19 que a Educação tem enfrentado globalmente têm fomentado reflexões sobre novas formas de ensinar e aprender no contexto escolar. Neste artigo, expomos o relato de experiência da condução do ensino de línguas dentro de uma abordagem complexa, que se deu no Ensino Médio de uma escola da rede pública por intermédio de ensino remoto, em um contexto imbuído de restrições de acesso à internet. O principal objetivo deste estudo consistiu em avaliar as possibilidades de alcance dessa abordagem, bem como seus pontos positivos e os obstáculos vivenciados. Por meio da análise desse processo, concluímos que é possível trabalhar a linguagem de forma efetiva dentro de uma perspectiva da complexidade, pois carrega os benefícios de um ensino multidimensional, não-linear, não-reducionista e transdisciplinar, o qual intenta incentivar a capacidade crítica do aluno, ao passo que trabalha fatores históricos, sociais, políticos, culturais e psicoemocionais, ensejando uma formação voltada para o sujeito integral, com atividades adequadas ao seu contexto e realidade atuais. Como obstáculos, presenciamos uma certa resistência de alguns alunos ao paradigma complexo de ensino-aprendizagem. O paradigma proposto estava embutido em um ensino que se apresentou de maneira não-fragmentada em disciplinas, e que, por ter um espectro maior de alcance e amplitude na abordagem dos temas propostos nas atividades requeria um posicionamento mais questionador e reflexivo por parte do aluno. Uma parcela desses alunos ainda demonstrou certo apego a uma visão mais cartesiana de se conceber o conhecimento, estando ainda enraizados aos processos tradicionais de ensino-aprendizagem.
A MERCANTILIZAÇÃO DA CULTURA NA NARRAÇÃO DE RODRIGO S.M., EM A HORA DA ESTRELA
Authors: Del Rio Araújo Bárbara
Published: March 2021

Este artigo pretende entender como a configuração narrativa desempenhada pelo narrador-personagem Rodrigo S.M. formaliza o atuante paradigma da indústria cultural na composição estética e também a problemática da identidade nacional ao seguir as novas tendências sobre o uso da linguagem. A premissa da pesquisa se relaciona às dificuldades colocadas no momento da narração, as quais suscitam, para além da discussão da escrita de si e da alteridade, “o sentimento acabrunhador da posição em falso de tudo o que concerne à cultura brasileira”. (ARANTES, 1997, p.14). O romance A hora da estrela, em função do engenho narrativo, se faz importante no questionamento dos limites da representação artística e no estatuto ambíguo da condição brasileira, a revelar que “a vida no capitalismo tardio é um contínuo rito de iniciação. Todos têm de mostrar que se identificam integralmente com o poder de quem não cessam de receber pancadas” (ADORNO, 2006, p.127). Em função dos personagens, Rodrigo e Macabéa, o romance de Clarice Lispector aproxima o trabalho do escritor ao da datilografa, contribuindo para evidenciar o esvaziamento ideológico da sociedade industrial e a inserção da cultura na lógica do fetichismo e da mercantilização. Assim, essa análise refletirá sobre como o narrador, apesar da sua racionalização, está atrofiado na capacidade de narrar, reproduzindo a implacável ideologia das massas.

Authors: Copetti Roberto , Amore Giulia , Giudice Caterina , Orso Daniele , Cola Silvia , Pillinini Pierpaolo , Rocco Chiara , Cappello Dario , Dibenedetto Alessia , Meduri Stefano
Published: March 2021

Purpose: The high percentage of asymptomatic patients and the non-high
sensitivity of real-time reverse transcription-polymerase chain reaction
(RT-PCR) test on nasopharyngeal swab cause some healthcare workers to be
infected but asymptomatic and a source of spread of the epidemic. This
study aimed to verify if the lung ultrasound (LUS) had enough high
negative predictive value to rule out coronavirus disease 2019
(COVID-19) among a population of healthcare workers operating in the
Emergency Department. Methods: A multicenter prospective observational
study was conducted, enrolling healthcare workers among the staff of two
Emergency Departments in Northeast Italy. The definitive diagnosis of
COVID-19 was established by an adjudication committee, based on the
clinical data and RT-PCR on nasopharyngeal swab result. Results: From
March 30, 2020, to April 22, 2020, we enrolled 155 cases. The
adjudication committee determined two true positives for COVID-19.
Twenty-one healthcare workers presented suggestive symptoms (2 true
positives and 19 false positives). The nasopharyngeal swab was positive
in one case (1 false-negative case). LUS was suggestive for COVID-19
pneumonia in 4 cases (2 false-positive cases). The diagnostic accuracy
of LUS was 98.7% (95% CI 95.4%-99.8%). The sensitivity and the
specificity of LUS were 100% (95% CI 15.8% -100%) and 98.7% (95%
CI 95.4% - 99.8%), respectively. The negative predictive value was
100% (95% CI 100% -100%). Conclusion: LUS has a good enough negative
predictive value for ruling out COVID-19 in a population of healthcare
workers exposed to COVID-19.

thromboembolisms.
Correlations between crack initiation and crack propagation lives of notched specimens under constant and variable amplitude loading
Authors: Fiedler Melanie , Vormwald Michael
Published: March 2021

This paper starts with an overview of the application of the three
guidelines (GL) of the German Research Association of Mechanical
Engineers (FKM). Each of these provides algorithms for calculating
fatigue lives of components under constant or variable amplitude
loading, however, with underlying different failure criteria, i.e.
technical crack initiation life (GL-nonlinear), fatigue crack growth
life (GL-fracture mechanics), and total fracture life (GL-linear). This
paper introduces the U-Concept which has been evaluated from a large
structural durability database. The U-Concept is a small add-on to the
Local Strain Approach (LSA) which is the backbone of the GL-nonlinear.
It enables 1) to directly calculate the fatigue life to total fracture
based on elastic-plastic material behaviour according to the LSA, or 2)
to estimate the remaining fatigue life from crack initiation to fracture
without a crack growth simulation.
A Stress Intensity Function for FCG Analyses in Metals
Authors: Kujawski Daniel
Published: March 2021

This paper presents a damaging stress intensity function
K for analyses of R-ratio effects on fatigue crack
growth (FCG) in metals. The proposed formulation is based on the sum of
strain and complementary energy and its role in FCG rate behavior in
threshold and Paris region at R-ratios ranging from -2 to 0.97. It
doesn’t invoke a crack closure assumption or fitting parameters for
R<0.5-0.6. For a high R>0.7 it utilizes an
experimentally determine correction factor, which accounts for excessive
plastic dissipation in the monotonic plastic zone (MPZ).
Approximate model for evaluation of thermal-hydraulic transients associated with rapid power increase in research nuclear reactor
Authors: Lipka Maciej , Madejowski Gawel , Prokopowicz Rafal , Pytelt Krzysztof
Published: March 2021

A simple model, for the estimation of changes in the nuclear fuel element
cladding temperature as well as the conditions of the formation of the
onset of nucleate boiling, is proposed. The results of this estimation are
sufficient to assess the effect of the transient with the peak of the
reactor's power on the device's safety, without the need for time-consuming
thermal calculations. The basic parameters determined using the proposed
model are the maximum wall temperature of the device in a hot spot, the time
constant of the wall temperature change, and the course of changes in the
onset of nucleate boiling ratio in time. The model may be used for
investigating the thermal behavior of thin heat-generating and water-cooled
elements (such as fuel elements or uranium irradiation targets) during rapid
power rise. The results of the temperature estimation with the proposed
model were tested considering the hot spot in the MR-6 type nuclear fuel.
The SN code with coupled kinetics and thermal-hydraulics, developed in the
MARIA reactor was used to validate the results. The maximum cladding
temperature, the thermal time constant and the onset of nucleate boiling
ratio parameter simulated by the SN code and the proposed scheme appeared to
be very consistent.
A study on the distribution of 85Sr and 134Cs radionuclides after total body irradiation
Authors: Nemcova Marketa , Andrejsova Lenka , Lierova Anna , Jelicova Marcela , Sinkorova Zuzana , Janda Jiri
Published: March 2021

The kinetics of strontium, 85Sr, and cesium, 134Cs, were evaluated in a
mouse experimental model to determine the impact of these radionuclides on a
living organism concerning total body irradiation. Our study demonstrates
that the elimination rate of 134Cs from the skeleton and teeth is influenced
by total body irradiation and the presence of 85Sr. Higher accumulation
and faster 134Cs elimination rates were observed in the skeleton and teeth
of mice administrated with a mixture of 134Cs + 85Sr radionuclides.
Regarding 85Sr, only a minimal effect was observed on its accumulation rate
in skeleton, teeth, and muscle in total body irradiation mice. The effect of
the 85Sr + 134Cs radionuclide mix on the accumulation of 85Sr was more
apparent in teeth, showing a higher retention rate after 10-24 days of
administration in non-irradiated mice. The evaluation of the kinetics of
these radionuclides provided much-needed insight on their effects during
the first two months after exposure, demonstrating that the accumulation
rate of 85Sr is greater than that of 134Cs. Further, the elimination rate of
the former is slower in comparison to the latter. Interestingly, total body
irradiation has a greater effect on the hematological parameters of the mice
blood than the radionuclides alone.

Presence of aflatoxins and deoxynivalenol in seeds of maize, spelt wheat and soya bean - preliminary research
Authors: Golijan Jelena , Lekic Slavoljub , Vukovic Gorica , Secanski Mile
Published: March 2021

Mycotoxins naturally contaminate plant - based food. Since organic
production does not allow the use of synthetic pesticides in plant
protection, many researchers state that organically produced foods are more
contaminated with mycotoxins than conven?tional ones. In this regard, the
aim of this study was to observe the content of aflatoxins B1, B2, G1 and G2
and deoxynivalenol, as the most common mycotoxins, in organically and
conventionally produced seeds of maize, spelt wheat and soya been during the
2015-2017 period. The HPLC/FLD and HPLC/DAD were used to determine the
presence of aflatoxins and deoxynivalenol, respectively. The highest number
of samples was not positive to the presence of these mycotoxins. Aflatoxin
B1 (1.16 ?g/kg) and deoxynivalenol (101.53 ?g/kg) were detected only in the
sample of organic maize harvested in 2015. Based on obtained results, no
conclusion can be drawn on the effects of organic and conventional
production on contents of mycotoxins in seeds of maize, spelt wheat and soya
bean, and further long-term studies are required.
Leucotelium cerasi (Bérenger) Tranzschel 1935, novel pathogen for mycobiota in Serbia
Authors: Bogosavljevic Stefan , Stupar Milos , Ljaljevic-Grbic Milica , Vukojevic Jelena
Published: March 2021

During the field studies on a strictly protected plant species Eranthis
hyemalis (winter aconite) in Serbia, it was noticed that certain individuals
were infected by some species of parasitic fungus. According to the
structure of spermogonia and aecia, as well as distinctive types of spores
recorded in infected leaves of winter aconite, the fungus was determined as
Leucotelium cerasi, known as a causative agent of rust in E. hyemalis and
Prunus species. Although it was first recorded in Serbia in Prunus spinosa
as a host (area of Valjevo in 1935), the appearance of this phytopathogen
was recorded in foliar tissue of E. hyemalis at four localities in Eastern
Serbia, near Knjazevac (Podvis, Golemi Kamen, and Ploca) and Zajecar
(Zmijanac). It was concluded that plants in natural populations of host
species were infected to a very high degree, as the number of infected
plants reached half of the total number of individuals in all studied
populations. Further research is neces?sary to determine to what extent this
fungus is threatening the survival of host populations and then implement
appropriate protection measures.
Program R in mapping of protected natural assets in Serbia
Authors: Lakicevic Milena
Published: March 2021

This paper deals with the tasks of creating maps of protected natural assets
(national parks and natural monuments - individual plant specimens) on
several case examples in Serbia. The main goal of the paper is to introduce
the application of the R program in diverse mapping assignments. Even
though the R program is commonly used for numerical and statistical
analysis, its application in mapping assignments is still relatively new and
not widely known. Therefore, this paper aims to promote the use of R in
mapping and to present the appearance of maps that can be obtained as a
result. The selected examples are shown on different spatial scales,
starting from the mapping of national parks on a map of Serbia, continuing
with the mapping of a single national park in a narrow spatial context,
ending with the mapping of individual protected plants. The same procedure
can be repeated for the similar mapping assignments in the future. Creating
maps is an integral part of defining adaptive management strategies for
protected natural assets, and therefore can greatly impact the process of
monitoring and conducting conservation measures for in situ plant protection
activities.
Numerical simulation and experiment of quenching process of 35CrMnSi by disk laser
Authors: Han Xing , Li Chang , Zhang Dacheng , Li Yunfei , Gao Xing
Published: March 2021

It is extremely difficult to reveal the thermo-mechanical coupling evolution mechanism of the laser quenching process by traditional experimental methods. The numerical simulation provides an effective way to obtain the dynamic evolution information of multifield coupling in the quenching process. Based on comsol multiphysics, a thermo-mechanical coupling model of the 35CrMnSi laser quenching process by a disk laser was established. In the model, the thermophysical parameters of the matrix during the quenching process were calculated by the CALPHAD method. The transient changes of temperature, phase change, and thermal stress during quenching were obtained by solving the model, revealing the transient change law of temperature field and microstructure transformation of a 35CrMnSi laser under different process parameters. The formation and transformation degree of martensite were characterized by the depth and width of the quenched transformation hardening layer. Laser quenching experiments of 35CrMnSi were carried out with a TruDisk 4002 laser. The quenching structure and phase transformation hardening rule were observed by Axioskop 2 SEM, Zeiss-ΣIGMA HD FE-SEM, and HXS-1000A micro hardness tester. Experiments show that the influence zone of laser hardening of a disk laser shows Gauss distribution. The quenching layer consists of complete quenching phase transformation zone, incomplete quenching zone, and core matrix in turn from the surface to inside. In the complete quenched zone, dense and fine acicular martensite and a small amount of retained austenite are formed, and the hardened layer is Gaussian distribution. The phase transformation layer width and the phase transformation layer depth of workpiece 1-1# are 10 352.9891 and 1091.0945 μm, respectively. The phase transformation layer width and the phase transformation layer depth of workpiece 1-2# are 6592.3963 and 754.6135 μm, respectively. The phase transformation layer width and the phase transformation layer depth of workpiece 1-3# are 4361.7892 and 416.2139 μm, respectively. The experimental results are in good agreement with the simulation results, which verifies the validity of the thermo-mechanical coupling model and provides a theoretical basis for obtaining the optimized process parameters.

O presente artigo teve como objetivo compreender os caminhos que estão sendo trilhados, pela comunidade acadêmica do IFMT, durante a Pandemia da COVID-19, com foco em suas relações com as mídias digitais. Para tanto, foi realizado um estudo com abordagem qualitativa, no qual foram analisadas três lives promovidas pelo SINASEFE/MT com os docentes, os discentes e os técnicos. A principal dificuldade relatada por professores e alunos foi a falta de acesso à internet de qualidade e de equipamentos por parte dos estudantes. Dessa forma, as principais ações administrativas mencionadas pelos técnicos objetivaram viabilizar o acesso aos alunos em condição de vulnerabilidade social. Ao considerar os resultados das análises se percebe que o período de isolamento social, apesar de ter suas ações caracterizadas pela improvisação, pode ser fonte de aprendizado para a comunidade acadêmica, todavia, isso depende de um planejamento robusto na retomada das atividades presenciais.

History in the Attic: Search for Roots in Ramabai Espinet’s The Swinging Bridge
Authors: Asha S.
Published: March 2021

In most of diaspora literature there is an attempt to retrieve the past. This makes one measure time in many ways, different calendars, change of seasons, past encounters narrated through wars, defeats, encounters and disasters. It is remembered through family history, ancestral heritage, nostalgia, memory and even through national disasters. This interaction portrays the immigrants caught in flight of memories, relationships and images. The relocation has its disgust for one thing or the other. The author has to live in the reminiscences, a collective memory representing a symbolic relationship between past and present. The Swinging Bridge  by Ramabai Espinet chronicles the multiple exiles that are part of the Indian experience in the Caribbean and Canada through two figures one from the past- great grandmother Gainder and the other from the present - Mona, the protagonist. The novel commemorates the maternal roots and routes of Indo-Caribbean history by establishing the subjectivity of widows and young girls from India who crossed the Kala Pani (Black waters of the Atlantic) in search of new beginnings in Trinidad and the great-grand-daughter who engages in an existential quest for selfhood in Canada. Grief motivates a flood of personal memories as Mona begins to remember intimate details of family life that had been repressed under the cover of migration. Bits and pieces of the past, fragments scattered in various places, childhood memories, overheard conversations, prayer songs, all come together in the attic. She explores the secret songs, photographs and letters giving her a powerful voice for her culture, her family, her fellow women and for herself. Mona’s drive to document history enables her to reveal the family’s carefully guarded secrets- domestic violence, drunken rampages, sexual abuse, illegitimate children, and even AIDS. This paper seeks to analyse the novel’s diasporic contents and find out whether this attempt at retrieval of the past brings about a change in the perception of today’s generation. The author brings to light the problems of a plural society calling for need for relationships and need for mutual respect- all to avoid conflict situations through this effective tracing of history in the novel.
Native Culture and Gender Politics in Nagaland: A Study of Easterine Iralu a Terrible Matriarchy
Authors: Gour Veena , Tripathi Dr. Shubhra
Published: March 2021

The paper aims at examining Easterine Kire Iralu’s novel A Terrible Matriarchy (2007) from feminist point of view.  The novel A Terrible Matriarchy is the coming-of-age story of a young girl, Dielieno. The narrative explores the suffering of innocent Dielieno and her confrontation with the traditional Angami society to which she belongs to. In the ethnic world of Nagaland, both patriarchal and matriarchal control co-exists but it also has a strong Tantric tradition from time immemorial. For various reasons the status of women in the northeast has not been different from the women in the mainstream of India. Easterine Iralu through her girl protagonist Dielieno depicts the severe gender discrimination where the grandmother neglected Lieno to the worst extent, always caring and preferring the boys. The grandmother's matriarchal hegemony makes Lieno revolt silently. The various aspects of women's marginal status and native culture have been analyzed in the paper.
Rushdie and the Problem of Exile
Authors: Jafri Dr. Shadan
Published: March 2021

Exile in the words of Wallace Stevens, is “a mind of winter” in which the pathos of summer and autumn as much as the potential of spring are nearby but unobtainable. Exile originated in the age-old practice of banishment. Once banished, the exile lives an anomalous and miserable life, with the stigma of being an outsider. Although it is true that anyone prevented from returning home is an exile, some distinctions can be made among exiles, refugees, expatriates and émigrés. Edward Said, in his work, Reflections on Exile, writes, “Refugees…are a creation of the twentieth-century state.” The word “refugee” has become a political one, suggesting large herds of innocent and bewildered people requiring urgent international assistance, whereas “exile” carries with it, I think, a touch of solitude and spirituality. Expatriates voluntarily live in an alien country; usually for personal or social reasons…An émigré is anyone who emigrates to a new country. (181) In this paper, I will take up Salman Rushdie and his experience of exile and try to analyse and differentiate the two kinds of exiles he underwent in his career.
Istanbul as Palimpsest: The Black Book as a Postmodernist Representation of Turkish History and Culture
Authors: Ayanee Aneesa
Published: March 2021

Orhan Pamuk’s novel, The Black Book is a postmodern chronicle of Turkey in which the author uses the structure of a detective novel to delineate the themes of identity, culture and hybridity. The paper aims to depict how Pamuk foregrounds that identities are never determinate but are forever eluding by presenting a love triangle which disappears underneath a mystical quest for one’s true self. Galip’s assuming the persona of his alter-ego, Celal; Prince Osman’s pursuit of true knowledge through reading diverse books and ultimately rejecting them; and Bedii Usta’s disillusion with the State for disapproving the mannequins, all represent the interlacing of cultures and interdependence of identities in contemporary Turkey. Moreover, in the novel, the rich Ottoman tradition and Islamic literature are also revisited in a postmodern light so as to present the allegorical and political connotations inherent in them. The paper also examines how the novel portrays the forced westernization and erasure of history and memories through the use of film ekphrasis to highlight how the Turkish citizens were lured by the Western cinema and indoctrinated about the superiority of the West so as to generate in them a sense of anxiety about their identities.
