Authors: Lobato Cruz Bárbara Beatriz
Published: April 2021

This article has as main objective to discuss the impact of the Coronavirus pandemic on the Brazilian Amazon, its consequences and conflicts not only in the forest but also in the people living in the region, especially the situation of indigenous peoples and how COVID-19 has been impacting the tribes directly and indirectly, through the exposure of opinions, facts and historical context, factors of paramount importance that help to build the current panorama of the Amazon within the pandemic. In addition, this article aims to analyse the political crisis that Brazil is facing at the moment and how it influences the impacts suffered by the Amazon macro-region, in order to highlight the need for discussion — now more than ever —, to protect and preserve Amazonian diversity in the face of a government that omits responsibility for the prevention of Amazonian identity. The concern with the Amazon rainforest is not something recent, however the current moment is decisive in the history of the largest tropical forest in the world.

According to official sources, the coronavirus pandemic that emerged in China in December 2019 has already infected more than 17 million and killed more than 666,850 people. Less impacted than the rest of the world, the Africa continent has nearly 890,000 confirmed cases as of July 30, 2020. According to the African Bank of Development, nearly 50 million Africans will be victims of extreme poverty as a result of the coronavirus pandemic; and this, following the global economic crisis due to this pandemic. It is shown that between 2020 and 2021, Africa will lose in terms of economic income ¼ of trillion dollars and that a contraction of 3.4% of GDP would be noticed. The risk of decline is justified by the decline in oil production by the main exporting countries, notably Algeria, Nigeria and Angola; in addition to the decline in commodity prices on the world market, the volatility of global financial conditions and natural disasters. Even if some analysts believe that the effects of this pandemic are temporary on the economy of the states, it is clear to note that they are perceptible on the world economy in general. In Africa, the low rate of infection, which is 5% since the emergence of the pandemic until July 30, 2020, is a favorable opportunity for the continent to recover and accelerate the process of its economic and regional integration.

Published: April 2021

Background: The average stage of attrition in permanent first and second molars is an established method of age estimation in the adult population. The study was conducted with an objective of age estimation from the average stage of attrition of permanent molars.Methods: A total of 451 individuals of age more than 20 years were examined. Nepalese individuals with intact first and second permanent molars in the maxillary and mandibular arch on either side were included. The average stage of attrition of the maxillary first and second permanent molars on either side was calculated and subjected to regression analysis to derive equations.Results: Among a total of 451 participants, 231 (51.22%) were females and 220 (48.78%) males, with a mean age of 44.3 ± 13.9 years. There was a strong correlation between age and average stage of attrition of molars. The correlation was stronger for upper molars compared to the lowers. Additionally, the mean of the difference between real age and estimated age was lower for maxillary compared to mandibular molars. Compared to age estimation by univariable regression, multivariable regression had greater accuracy. Similarly, estimation of age from maxillary molars was more accurate as compared to mandibular (difference in years: 3.82 ± 3.03 for maxillary molars and 5.17 ± 4.2 for mandibular molars).Conclusions: Maxillary teeth are better for age estimation and using both maxillary first and second permanent molars gives better accuracy.Keywords: Age estimation by teeth; age reporting; forensic anthropology; forensic dentistry; tooth attrition

Boris Šerginin pohjoinen
Authors: Perkiömäki Mika
Published: April 2021

Artikkeli tarkastelee ekokriittisestä näkökulmasta neuvostoaikaisen kirjailijan Boris Šerginin pomorien kansanperinteeseen perustuvista kertomuksista koostuvan tuotannon pohjoisen kuviteltua maantiedettä sekä sen suhdetta luontoon muun muassa kristinuskon ja neuvostomodernisaation konteksteissa. Se esittää, että Šerginin tuotanto rakentaa pomorien narratiivista identiteettiä, jolle keskeisiä ovat rikas elämä meren ehdoilla luonnonvarojen puolesta köyhällä alueella, kristinusko, vanha kulttuuriperintö sekä yhä uusien pohjoisten alueiden hallinta uusien teknologioiden avulla. Šerginiä Venäjän pohjoisen sakraalin maantieteen ja venäläisen kirjallisuuden pohjoisen tekstin kautta lukeva tutkimus on hahmottanut Venäjän Pohjolan kollektiivista identiteettiä keskittyen sen mytopoeettisiin merkityksiin. Tämä artikkeli tuo Šerginin materiaalisen ympäristön vahvemmin esiin ja tarkastelee Šerginin pohjoisen tekstin tutkimusta osana pomorien narratiivista identiteettiä.

The North of Boris Shergin

This article examines from an ecocritical perspective the imagined geography of the North in Boris Shergin’s works, a Russian writer of the Soviet period, whose stories were based on Pomor folklore. It studies the interconnections of nature and people in Shergin’s stories in the contexts of Christianity and Soviet modernisation. The article argues that rich life by and from the sea in an area poor in natural resources, Christianity, rich cultural heritage, and mastering new northern regions with the help of new technologies are central for the narrative identity of the Pomors whom Shergin’s oeuvre concerns. The research on Shergin from the points of view of the sacral geography of northern Russia and the northern text of Russian literature has outlined the collective identity of the Russian North, focusing on its mythopoetic meanings. This article builds more strongly on the material environment in Shergin’s stories and considers the research on Shergin’s northern text as part of the narrative identity of the Pomors.
Kolonialistiset välitilat Pienen pimeyden kuukaudessa
Authors: Lukin Karina
Published: April 2021

Artikkelissa tarkastellaan nenetsikirjailija Vasili Ledkovin romaania Pienen pimeän kuukausi (Mesjats maloi temnoty), joka on historiallinen, porojen kollektivisoinnista 1920- ja 30-lukujen Nenetsien kansallisessa piirikunnassa kertovat teos. Romaania tulkitaan kyläproosan keinoja ja keskustelutilaa hyödyntävänä tekstinä, joka nostaa esiin porojen omistamiseen ja ihmisen ja poron vuorovaikutukseen tulleiden muutosten aiheuttamia ristiriitoja sekä kollektivisointiin liittyvää väkivaltaa. Lukutapaa luonnehtii jälkikoloniaalinen ote, jossa painottuu vähintään kahdenlaisten tulkintojen yhtäaikainen läsnäolo ja niiden limittyminen toisiinsa. Analyysissä keskitytään tekemään ymmärrettäväksi poron ja ihmisen välistä suhdetta poropaimentolaiskäytänteissä ja tuodaan esiin, miten romaanin hahmojen erilaiset tavat toimia heijastavat nenetsien konventioita tai asettuvat niitä vastaan. Samalla osoitetaan, että teksti tuottaa myös sosialistisen realismin ja neuvostoliittolaisen kyläproosan perinteen mukaisia mielikuvia, ja pohditaan, miten nämä ovat osa romaanin tarjoamaa kriittistä katsetta nenetsien menneisyyteen.

Colonial in-betweens in The Month of the Small Darkness

The article discusses the Nenets writer Vasili Ledkov’s historical novel The Month of the Small Darkness, which describes the collectivisation of the reindeer in the Nenets national district in the 1920s and 1930s. The novel is analysed as a text using the textual and poetic strategies of the discursive space created by what was called the village prose movement. At the same time, the novel brought out the violence related to collectivisation and the ambivalence produced by changes in the ownership of the reindeer and the interaction between the humans and reindeer. The novel is read from a postcolonial perspective, emphasising at least two kinds of simultaneous interpretative models and the way they fold into each other. The analysis focuses on understanding the relationship of reindeer and humans in the practices of nomadic reindeer-herding and on explaining the differing actions of the characters and their relations with Nenets conventions or Soviet ideologies. According to the interpretation, the novel gains its critical gaze towards the Soviet past from its position within socialist realism and the discourses of the village prose movement that are, as such, hybrid forms of literature.
Kuvitteellisia periferioita
Authors: Kuikka Eeva
Published: April 2021

Artikkeli tarkastelee nenetsikirjailija Anna Nerkagin pienoisromaaneja Nogo-suvun Aniko (1976) ja Valkea jäkälä (1996) sekä venäläisen elokuvaohjaaja Vladimir Tumajevin näiden teosten pohjalta ohjaamaa elokuvaa Valkea jäkälä (2014). Lähestyn teoksia kysymällä, kuinka niissä kuvataan arktista tundraa tilana ja kuinka teoksissa kuvattu perifeerinen tila esitetään suhteessa valtakeskuksiin. Artikkelin tärkeimpinä teoreettisina viitekehyksinä toimivat geokritiikki sekä jälkikolonialistinen teoria. Nerkagin teoksissa tundra näyttäytyy muusta maasta irrallisena alkuperäiskansan toimintaympäristönä, joka kytkeytyy sekä nenetsien historiaan että näiden suhteeseen ei-inhimillisen luonnon kanssa. Erityisesti Valkean jäkälän voi nähdä myös kritisoivan yhteiskunnan tapaa laiminlyödä alueen asioiden hoitoa. Tumajevin elokuva puolestaan nojaa venäläisessä kulttuurissa vallitseviin käsityksiin arktisesta tundrasta ja heijastaa myös Venäjän 2000-luvulla aktivoitunutta tarvetta profiloitua arktisena suurvaltana.

Imagined Peripheries

Abstract: This article focuses on Nenets author Anna Nerkagi’s short novels Aniko of the Clan Nogo (1976) and The White Moss (1996) and their film adaptation The White Moss (2014) by Russian film director Vladimir Tumaev. I approach these works by asking how they depict the Arctic tundra as a space and how they describe the relationship between this peripheral space and the power centres. The main theoretical frameworks used are geocriticism and postcolonial theory. Nerkagi’s works depict the tundra as a region that is disconnected from the rest of the country and defined by Nenets history and the relationship with non-human nature. Especially in The White Moss, the reader can also notice a social critique of the neglect of the region. Tumaev’s film, on the other hand, relies on Russian cultural conceptions of the Arctic tundra and reflects Russia’s urge to be profiled as an Arctic superpower in the 2000s.

Authors: Vorona Anna
Published: April 2021

У статті розглянуто окремі складові інноваційного механізму національної економіки, їх функції та основні завдання. Досліджена роль підприємств як системоутворюючого складника сталого інноваційного розвитку національної економіки.

Висвітлено рівень зацікавленості підприємств у веденні інноваційної діяльності, розглянуто фактори, що впливають на зацікавленість підприємств інноватизацією виробничого процесу. Проаналізовано джерела фінансування інноваційної діяльності підприємств, досліджена структура фінансування інноватизації у період 2012-2018 рр. За результатами дослідження виявлено: здійснення інноваційної діяльності доцільне лише у разі її прибутковості, яка перевищує прибутковість традиційних підходів різних видів економічної діяльності.

Зазначено, що кредитування інноваційної діяльності, яке у багатьох країнах є фінансовою основою інноваційних процесів, в Україні гальмується, зокрема, обмеженим обсягом довгострокових ресурсів, високою вартістю інноваційного банківського кредитування, відсутністю непрямої підтримки у вигляді знижених ставок для інноваційно зацікавлених підприємств. Венчурне інвестування, франчайзинг, індустріальні та технопарки в Україні перебувають на етапі початкового розвитку.

Розглянуто процес трансферу технологій як основного показника ефективності діяльності науково-технічної сфери економічної діяльності, законодавчу складову його існування та методологію державної підтримки. Проведено аналіз динаміки обсягів трансферу технологій у період 2012-2018 рр., зроблено висновок про активізацію інноватизації у сферах енергетики, наноматеріалів і технологій, охорони природнього середовища, інформаційно-комунікаційних технологій, а також зниження рівня інноваційної діяльності у сфері транспорту, медицини та АПК.

Published: April 2021

O pneu, por ser essencial para as atividades da vida moderna, se tornou um dos produtos de maior consumo no mundo e um dos resíduos mais problemáticos por sua difícil decomposição na natureza. Devido a isso, uma solução para o problema é o aproveitamento de resíduos de pneus na substituição à areia na composição do concreto podendo ser uma alternativa para o desenvolvimento sustentável do setor da construção civil. Através do método ABCP/ACI, os corpos de prova foram moldados com traço de 1,29:2,28:0,5 e seus resultados mostraram que a resistência à compressão diminuiu com o aumento da porcentagem de resíduos de pneu. Contudo, os corpos de prova adicionado com 15% de metacaulim apresentaram um aumento da resistência a compressão com o crescimento da porcentagem de resíduo de pneu. Também observou que os valores de absorção de água diminuíram da amostra REF-15M para a amostra com 15%RP-15M. Além disso, observou-se também um aumento da absorção de água nas amostras ausentes de metacaulim para as amostras com adição de 15M de metacaulim.

O exercício calistênico intermitente de alta intensidade (ECIAI) é considerado um método eficaz e de baixo custo para a melhora da aptidão física e da composição corporal. O objetivo do estudo foi avaliar os efeitos agudos de uma sessão de ECIAI sobre percepção subjetiva ao esforço (PSE), saturação de oxigênio (SpO2) e variáveis hemodinâmicas em praticantes avançados. Foram avaliados 8 homens praticantes da modalidade Cross Training e CrossFit®. O protocolo consistiu em 4 séries com o máximo de execuções durante 30 segundos, seguido de 2 minutos de descanso. A PSE foi avaliada imediatamente após cada série. A SpO2, frequência cardíaca (FC), pressão arterial sistólica (PAS) e pressão arterial diastólica (PAD) foram aferidas no repouso e imediatamente após cada série. Os valores foram expressos como a média ± desvio padrão da média. Não ocorreu diferenças entre as séries na PSE. Houve aumento da FC (bpm) após a realização das séries 1, 2, 3 e 4. Quanto a PAS (mmHg), foi observado aumento após as séries 2 e 3 quando comparado ao repouso. A PAD (mmHg) não foi alterada. A PAM (mmHg) aumenta imediatamente após série 2 e 3 quando comparado ao repouso. O Duplo Produto também apresentou aumento imediatamente após todas as séries quando comparado ao repouso. Os resultados do presente estudo indicam que o ECIAI promoveu importantes ajustes cardiorrespiratórios em adultos com experiência nessa modalidade de exercício. Estes efeitos caracterizam um esforço físico vigoroso e reforçam a importância do controle fisiológico da carga interna durante a sessão de treinamento.
Construindo um modelo didático 3D de baixo custo para facilitar a aprendizagem da membrana plasmática no Ensino Médio e Fundamental
Authors: Gonçalves Tiago Maretti
Published: April 2021

Sendo caracterizada como um mosaico fluido, a membrana plasmática celular é uma bicamada composta de fosfolipídios e proteínas proposta por Singer e Nicolson em 1972. É uma estrutura tridimensional fascinante possuindo diversas funções como permitir a integridade e o transporte de substâncias para dentro e para fora da célula. Principalmente no Ensino Médio e no Fundamental, as disciplinas de Biologia e Ciências, possuem tópicos de Citologia, e os mesmos são encarados pelos alunos como complexos, abstratos, dificultando sua visualização e compreensão, uma vez que abordam estruturas tridimensionais microscópicas. Para vencer tais obstáculos e facilitar a aprendizagem dos alunos, este artigo propõe uma oficina com o objetivo de construção e abordagem de um modelo didático 3D da membrana plasmática das células eucarióticas, utilizando materiais simples e de baixo custo. Acredita-se que, a confecção e a abordagem desse modelo 3D permitam facilitar o entendimento do tópico proposto, além de promover uma maior motivação dos alunos no processo de aprendizagem, despertando-se assim o lado lúdico e criativo dos discentes.
Assédio sexual no ambiente laboral: Um estudo com servidores públicos de uma universidade federal do Rio Grande do Sul
Authors: Farencena Gisela Sartori , Kocourek Sheila , Costa Vívian Flores
Published: April 2021

O assédio sexual no ambiente de trabalho é uma realidade que atinge diversas organizações. Em muitas instituições, este tipo de violência ocorre especialmente quando há relações de poder e hierarquia envolvidas, e está diretamente ligada a questões culturais, como o machismo e o patriarcalismo, que acabam colaborando para casos de violência, muito em parte interligadas à discriminação de gênero. Este estudo tem por objetivo analisar a incidência de situações que configuram assédio sexual entre servidores de uma Universidade Federal do Interior do Rio Grande do Sul, a partir do Modelo de Avaliação de Experiências Sexuais proposto por Fitzgerald et al. (1999). Para isto, foi realizado um estudo de caso, de cunho quantitativo e caráter descritivo, cujo público-alvo compreende os servidores da instituição. A coleta de dados foi realizada com aplicação de questionário on-line, por meio do próprio sistema da Instituição, contando com a participação de 513 servidores. A análise de dados envolveu estatísticas descritivas, a partir do Sofware SPSS 20. Como resultados, percebeu-se que a maioria dos servidores nunca vivenciou as situações apresentadas no questionário. Apesar disso, há casos de assédio sexual ocorrendo tanto contra mulheres quanto contra homens servidores da instituição, mas as estatísticas evidenciaram que são elas as maiores vítimas dessa forma de violência.

Published: April 2021

Esta pesquisa se propõe a contribuir, para o uso da gamificação na prática do professor no ensino superior na modalidade a distância, como uma abordagem metodológica ativa e favorável a fim de auxiliar o docentes em suas ações de transmitir o conhecimento de forma clara e eficiente, trazendo ao aluno uma aprendizagem significativa, dinâmica, interativa e interessante, que o envolva na construção de seu aprendizado. No cenário educacional, inovar saberes no processo de ensino/aprendizagem é o que almeja o sistema de educação diante do novo contexto tecnológico. Desta maneira, é percebida a carência de professores quanto ao uso das metodologias ativas com condições de conhecimentos diferentes, fazendo do ambiente virtual apenas uma plataforma de conteúdo. Este artigo objetiva produzir um estudo sobre as principais técnicas, abordagens e ferramentas para uso da gamificação em Ambientes Virtuais de Aprendizagem (AVA) no Ensino Superior da Educação a Distância (EAD). O estudo teve uma pesquisa bibliográfica, com leituras exploratórias, descrevendo os conteúdos de forma qualitativa. As bases de leituras usadas para o estudo foram Google Scholar, Scielo e periódicos abertos da Capes. Nos dados apresentados, notou-se ausência de formação continuada para os professores que atuam nas instituições de ensino superior em EAD. Especificamente, a gamificação, sendo pouco ou quase nada aplicada na prática dos professores, como também, percebeu-se o quanto a utilização de técnicas de jogos educativos na prática pedagógica no AVA pode melhorar o ensino aprendizado, tornando professor e alunos protagonistas na desconstrução e construção de novos conhecimentos diante da nova perspectiva de cidadãos que o mundo deseja.

Initial Behavior of Additives and Mechanical Properties of Copper Foils on High Current Density
Authors: Woo Tae-Gyu , Park Jong-Jae , Park Il-Song
Published: April 2021

In this study, we studied the surface and mechanical properties of multiple additives as well as the initial plating properties of individual additives. With the individual additive groups, copper crystals tended to converge at a stage above the critical amount of additive. When chloride ions were added, large crystals formed at several places on the surface. Thereafter, small crystals were attached to and grew on the surface of the large crystals. When collagen and JGB (Janes Green B) were added individually, the crystals were more uniformly distributed on the surface as compared with the group with added chloride ions. In addition, starlike crystals were grown depending on the amount of addition. It was necessary to use multiple additives, which is why it is difficult to make a uniform surface layer with individual additives. Large crystals of more than 10 μm formed unevenly on the surface treated with multiple additives of chloride ions and MPSA (3-mercapto-1-propane sulfonic acid). Large crystals disappeared on the surface treated with additional collagen along with multiple additives. However, valley like shapes were observed on this surface, due to the large crystals. But, addition of JGB additives to this reduced the valley and formed a uniform plating layer. MPSA and 20 ppm of collagen were added as multiple additives, grain sizes increased by 93.5% (220 peak) and 172.3% (311 peak) compared with the non-additive group. As a result, tensile strength decreased by 24.5% and elongation increased by 17.8%. The crystal size was reduced 25.0% on average by the addition of 10 ppm JGB, which contributed to a 5.4% increase in tensile strength and a 16.0% decrease in elongation. The grain size and surface properties could be controlled by adding multiple combinations of additives. As a result, It was confirmed that mechanical properties could be controlled by the proper amount and the optimum combination of additives.
Synthesis of Mesoporous Carbon from PVDF and PTFE via Defluorination of 1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU)

Porous carbon has found commercial applications as a filter material based on the sorption ability of its pores. The pore size and surface properties of the carbon can be varied depending on the type of particles to be filtered. Here, mesoporous carbon was induced through the pyrolysis of polyvinylidene fluoride (PVDF) to fabricate a porous material for microparticle filtration. Because removal of the constituent fluorine at elevated temperature leaves small-sized micropores, the PVDF precursor mainly generates micropores during pyrolysis. To suppress the micropore evolution mechanism, the PVDF precursor was defluorinated before the heat treatment using 1,8-Diazabicyclo[5.4.0]undec-7-ene(DBU) and then pyrolyzed. The suppressed evolution of the micropores during carbon synthesis leads to a lower specific surface area, suggesting low adsorption capacity. The polytetrafluoroethylene (PTFE) was mixed with the PVDF precursor to induce mesoporosity. The PVDF precursor mixed with the PTFE enhanced the surface area since the PTFE could be removed, leaving mesopores after pyrolysis. The effect of the defluorination process on the porosity was investigated by varying the ratio of DBU to vinylidene fluoride unit (1, 5, 10, 20) in the precursor solution. With higher DBU content in the precursor, the micropore evolution was reduced with a lower specific surface area. The porous carbons synthesized from the precursor with a high DBU amount (DBU/vinylidene fluoride unit = 5, 10, 20) were almost entirely composed of mesopores. In addition, the higher DBU content reduced the hydrophilicity of the synthesized carbon. In summary, to separate and absorb relatively large impurities, the mesoporous carbon should be synthesized using a mixture of PVDF and PTFE precursor with an appropriate amount of DBU for a higher specific surface area.
And Don't Forget Phenomenology, Etc.
Authors: Gaston Sean
Published: April 2021

After 1967, for some twenty years it appears that Derrida has little to say about Husserl. In the late 1980s he returns to Husserl and reiterates his early critiques of the limitations of phenomenology in relation to European humanism. However, in the 1990s there is more than just a return to Husserl, there is also a re-evaluation, prompted by the publication of Derrida's 1953–1954 thesis on phenomenology. This article focuses on Derrida essay from 2000, ‘Et Cetera … (and so on, und so weiter, and so forth, et ainsi de suite, und so überall, etc.)’, which is both the development of a footnote from 1961 and a reminder to his readers to not forget the importance of phenomenology in the history of deconstruction. Focusing on the idealised status of the ‘etc.’ in phenomenology and Husserl's remarkable account of the syncategorematic ‘and’, Derrida's essay suggests that we must think of both ‘deconstruction … and phenomenology’ and of the tradition and legacy of phenomenology as a limit for deconstruction.
Thinking the Ghost: Tragedy and the History of Theory
Authors: Reynolds Anthony
Published: April 2021

In this paper I examine the role of tragedy in the ancient emergence of philosophical interiority and in the recent return of exteriority that marks the birth of theory. I argue that tragedy names a kind of epistemic threshold between systems of knowledge predicated on exteriority and interiority. I conclude by arguing that Derrida's late effort to articulate a messianic model of the tragic in Specters of Marx and elsewhere, his effort to “think the ghost,” both confirms and complicates tragedy's place in the history of theory.
Troubled Origins: Accounting for Oneself (Derrida with Botho Strauß and Didier Eribon)
Authors: Richter Gerhard
Published: April 2021

Even after the concept of ‘origin’ has been called into question, a troubling wish to speak of origins persists, especially in the narrative act of accounting for one's own origins in confessional discourse. Here, the self encounters the limits of its narratibility, even as it interrogates how, in the Nietzschean sense, it became what it is. This essay explores the question of troubled origins by placing Nietzsche's Ecce Homo: How One Becomes What One Is and Derrida's Monolingualism of the Other; or, the Prosthesis of Origin in syntactical relation with Didier Eribon's Returning to Reims and Botho Strauß's Herkunft ( Origin). The essay meditates on the ways in which a world-oriented longing for identification persists long after the ideas of identity and self-identity have been bid farewell. If there is a kind of survival to be espied in textual acts of confronting one's troubled origins, such survival would have to travel through a language that unfolds on the far side of any conventional identity-thinking. By the same token, this language could never simply resist the conceptual and rhetorical temptation powerfully exerted by the seductive processes of identification. Derrida, Strauß, and Eribon, each in their own idiomatic way, implore us to question just what such textual acts of commemorative survival imply for a thinking to come.
Giving Hegemonic Masculinity a Face Lift: Masquerade in John Woo'sFace/Offand the Somatechnics of Masculinity in Crisis
Authors: Bowen Kate
Published: April 2021

In 1990s America, the question of what made a ‘real’ man was at the forefront of debates about sex and gender. During this pivotal moment in American history, hegemonic masculinity in particular was experiencing numerous threats to its ontological security. For instance, masculinity was infamously pronounced in crisis, the advent of the ‘new man’ betrayed anxieties about an image-conscious and feminine performance of masculinity, and there was mounting social pressure from civil rights, feminist, and queer groups for straight, white, masculinity to be challenged as the centre of the patriarchal stage. In short, the issue for masculinity in the 90s was that of legitimacy. The response from Hollywood was an influx of films which featured leading men in costume, disguise, or masquerade. John Woo's Face/Off is one such film that betrays anxieties about the constructedness of hegemonic masculinity. Face/Off does so through the motif of plastic surgery. In this article, I will explore how Face/Off uses the image of plastic surgery to represent the masculinities of its male protagonists as masquerades. I will demonstrate how plastic surgery in Face/Off is a device which transforms hegemonic masculinity so that it may adapt to the climate of crisis and secure its continuation. Face/Off demonstrates that masculinity is a construct which masquerades as an ontology.
Huronia's Double Bind: How Institutionalisation Bears Out on the Body
Authors: Rinaldi Jen , Rossiter Kate
Published: April 2021

Frequently missing from histories of forced institutionalisation are close readings of the enduring impact on survivors' corporeality. In this article the authors analyse interview data featuring people who survived the Huronia Regional Centre: a total institution designed to warehouse people with intellectual disabilities that operated in Canada from 1876 to 2009. These interviews reveal the impact of institutional technologies on the bodies of the institutionalised, and how institutional survivors resisted those technologies. Institutional rituals meant to organise and cleanse residents, resulted in the reification of institutional subjects as inescapably contaminated. Drawing from Mary Douglas's theory of dirt and Julia Kristeva's interpretation of dirt as abjection, the authors engage with interview data on daily institutional care routines, particularly dressing, eating, showering, and the administration of medication, to show how these rituals produced for the institutionalised subject meanings around gender and disability as markers of defilement. The authors argue that the kinds of deeply oppressive and often violent rituals central to lived experiences of institutionalisation are grounded in the assumption that disabled gendered bodies are already-abject, hence the institutional demand for the institutionalised to be brought under control.
Nordic research on special needs education in upper secondary vocational education and training: A review
Authors: Holmgren Robert , Pettersson Gerd , Ström Kristina , Björk-Åhman Camilla
Published: April 2021

The purpose of this article is to describe and analyse the state of the art of research on special needs education (SNE) in the context of the Nordic countries’ vocational education and training (VET) systems during the period January 2010 to September 2018.  Twenty studies remained after the search procedure and thematic analysis, 15 of which deal with the practice level and five with the organisation level. No studies were identified as belonging to the policy level. The following themes were found at the practice level: teachers’ work and role, teaching and learning, student transition and student dropout. Themes identified at the organisation level were changes to vocational policy documents and educational practices, and school organisation and its implementation. Finland dominates in terms of number of studies. Furthermore, the review shows that there were few studies in the area of SNE in VET. The results show that further studies are needed to acquire more knowledge about SNE in vocational education.

Oral cancer is an important aspect of dentistry and should be screened for daily in day to day practice. A systematic cross-sectional survey was conducted. 183 dental students participated in the study by answering a self- administered validated questionnaire. The questionnaire consisted of sixteen questions, relating to the knowledge, attitude and practice. The statistical analysis was conducted using Pearson’s chi-square testing.73.8 % of students had accurate overall knowledge regarding Oral Cancer, which was satisfactory. About 32.2% of students claimed to have adequate up-to-date knowledge regarding the prevention and detection of oral cancer. 81.4% students had appropriate attitude towards Oral Cancer. 88% of students employed apposite practice management skills with respect to examining patients for any cancerous lesions and took efforts for counselling the patient. Yet, 97.8% of students demanded additional training regarding identification and prevention of oral cancer.The study suggestively indicated that the dental students have satisfactory knowledge, attitude and are cognizant in examining for symptoms of oral cancer. No significant difference between knowledge /attitude/ practices about oral cancer amongst the three undergraduate years. Additionally, innovative and didactically orientated programmes should be reinforced to upsurge awareness which will aid in timely detection.The main objective of the study was to assess the level of knowledge, attitude, practice concerning oral cancer amongst undergraduate dental students of Maharashtra Institute of Dental Sciences & Research Dental College, Latur, Maharashtra, India.

Aggressive or conventional osteoblastoma: a diagnostic dilemma
Authors: Lavanya N
Published: April 2021

Osteoblastomas are primary benign bone forming tumours which are not common in the cranio - facial region. Here, we present a case of recurrent osteoblastoma in a 25 year old male which involved the maxilla and extended into the adjacent maxillary sinus and nasal cavity. The involvement of maxilla with destruction of paranasal air sinuses is quite rare. We also discuss the histological differential diagnosis, along with clinical features helped to arrive at the correct diagnosis.
