Preadolescent EFL learners’ self-efficacy expectancies before and after completion of a grammar task: Multivariate analyses of grade level, gender, and performance effects
Authors: Faber Günter
Published: November 2020

Learners’ task-specific self-efficacy expectancies have gained increased attention in the EFL context. Across various competence areas they have been demonstrated to substantially affect learners’ motivation, learning approach, and performance. However, certain research gaps still exist – particularly concerning younger learners’ grammar self-efficacy. Furthermore, though conceptually assumed to play an essential role in learners’ self-efficacy formation and calibration accuracy, little is empirically known about task completion effects. The same applies to the role of grade level and gender differences in lower secondary EFL classrooms. Against this background, the present study addressed the effects on preadolescent learners’ self-efficacy expectancies before and after completion of a grammar task. In a sample of 212 preadolescent learners at secondary grade 5 and 6 their self-efficacy expectancies were analyzed before and after task completion. ANOVA results and post hoc analyses indicated task completion effects to exist in a most differentiated manner – and to substantially depend on an interaction between learners’ grade level, gender, and task performance. Fifth-graders’ but not sixth-graders’ self-efficacy expectancies were more accurate after task completion. Most remarkably, it was the male fifth-graders in the high performing group who initially overestimated their grammar performance and perceived their capabilities more realistically after task completion. Thus, it is a matter of careful differentiation for teachers to support effective self-efficacy cognitions of EFL learners during secondary grades. In research, repeated measurement of individual self-efficacy estimates before and after task completion can help to reveal more about the ongoing process of self-concept development.
The role of identity styles and social support from peers on emotional engagement in the English as a foreign language learning
Authors: Al-Amri Majid
Published: November 2020

This present study was designed to investigate influences of identity styles and social support from peers on emotional EFL classroom engagement in a large sample of Saudi early adolescents (N=406) ranged in age from 12 to 15. This emotional engagement construct is based on the identity styles literature and draws upon concepts of social support received from peers as one of the most important sources of validation from others during adolescence period, and as a mediating variable of the associations between students’ identity styles and emotional engagement. The study shows gender differences within the sample. In general, the findings of the study demonstrate the role of social support received from peers in enhancing identity styles and influencing emotional EFL classroom engagement.

THE MEANS TO CONTROL THE MIND
Authors: Upadhyay Dr. B. N. , Gohil Mrunaldevi
Published: November 2020

The ashtāng yoga system of yoga as presented by sage Patanjali classifies yoga into a series of eight steps, at the end of which the highest aim of human life, i.e. self-realisation can be attained. One can get some knowledge about what these steps are by reading sage Patanjali’s Yoga-sūtra. However, how the aim of yoga can be attained and what are the means of attaining it cannot be easily known because the Yoga-sūtra comprises of aphorisms, which by their very nature, can be understood only if one has a thorough knowledge of the subject. This paper is an attempt to figure out the means of reaching the highest aim of yoga through the study of the Yoga-sūtra, one of the most authoritative text on the subject of yoga and another gigantic scripture in the field of yoga, the Bhagwad Gita, which is also known as the Yoga shāstra. Further, the nature of these texts is such that only an advanced yogi can understand its true meaning through his/her experiences. Therefore, the works of Swami Kripalvanandaji and Swami Rajarshi Muni have also been studied to throw more light on the subject.
Workers Who Produce Industrial Fabrics and Cultivate the Land: Textile Labor, Migrations and Connections between Rural and Factory Work
Authors: Da Silva Barbosa de Mello Juçara , Dos Santos Ribeiro Felipe Augusto
Published: November 2020

This article explores the experiences of migrant workers, many from rural areas, who settled in a major center of the textile industry in Brazil, located in the state of Rio de Janeiro and which housed to four factories. Articulating several historical sources, we seek to understand both the agricultural practices maintained by migrants from the countryside, and the incentives to work in the fields fostered by employers in the factories. In contrast to studies guided by notions of modernization which have crudely linked the manufacturing world to progress as opposed to the agricultural, this article examines how rural and factory labor coexisted in multiple combinations. We argue that the term “roçado operário” (factory worker’s farm), used in many studies, is not enough to describe a far more varied and complex social phenomenon. Therefore, we propose a new framework for understanding the various forms of land use by these workers.
Workers Who Benefit from the Exploitation of Other Workers
Authors: Van der Linden Marcel
Published: November 2020

Often, all too often, global working-class solidarity remains fragile, conditional or fails to be realized in practice, whatever the lofty rhetoric may be. The present paper explores one possible explanation: workers in the North profit from the exploitation of workers in the South through cheap commodities and services, and additional job opportunities. For example, wage-earners in the North can buy T-shirts so advantageously because their real wages are much higher than the real wages of labourers in the Global South. This is what I would like to call a relational inequality within the world working class: some workers are better off because other workers are worse off. The paper presents a very tentative historical outline of global relational inequality since the 1830s.

Rendahnya kualitas pelayanan publik di Indonesia sudah lama menjadi keluhan masyarakat. Hal ini  ditandai  dengan rumit dan mahalnya harga pelayanan, serta  sulitnya untuk memperoleh akses terhadap pelayanan publik .  Kondisi demikian tidak sejalan dengan  upaya pemerintah  untuk  mewujudkan pelayanan prima kepada masyarakat. Dikeluarkannya   UU No. 25 Tahun 2009 tentang Pelayanan Publik,   merupakan langkah dan harapan besar akan terwujudnya pelayanan publik yang berkualitas. Di dalam UU No. 14 Tahun 2008 tentang keterbukaan informasi publik dikatakan bahwa informasi publik diartikan  sebagai informasi yang dihasilkan, disimpan, dikelola dan atau dikirim/diterima oleh suatu badan publik yang berkaitan dengan penyelenggaraan Negara dan/atau penyelenggara dan penyelenggara badan publik lainnya yang sesuai  dengan UU ini serta informasi lain yang berkaitan dengan kepentingan publik. Aksessibilitas informasi merupakan dimensi yang mempengaruhi pelayanan publik, hal ini didasari oleh pemikiran bahwa secara subtansial pengelolaan informasi publik saat ini telah mendapatkan perhatian serius  dari berbagai kalangan, baik pemerintah maupun  lembaga publik lainnya. Informasi publik merupakan hak dasar yang mesti dipenuhi oleh lembaga publik untuk disebarkan kepada masyarakat. Oleh karena itu dibutuhkan pengembangan  sistem dan metode pelayanan informasi publik yang terpercaya dalam pelaksanaan pelayanan publik  Ketersediaan informasi pelayanan yang selalu “up to date” dan transparan merupakan kebutuhan yang mutlak diperlukan berupa informasi mengenai data dan dokumen yang diperlukan secara lengkap dan mudah diakses oleh masyarakat  terkait dengan jenis layanan yang dibutuhkan.

Introduction : Divided Memories, Shared Memories, Poland, Russia, Ukraine: History mirrored in Literature and Cinema
Authors: Amacher Korine , Aunoble Eric
Published: November 2020

In 2017, general-interest magazines illustrated the centenary of the Russian Revolution with stills from Eisenstein’s October [Октябрь] (1927). One strikingly showed soldiers rushing across a square to represent the storming of the Winter Palace by Bolshevik fighters on 7 November 1917. In reality, the actual assault was slow and even laborious. But for Western audiences, this film sequence has become an archive image, a piece of history. This type of substitution of artistic representation for historical reality conflicts with the positive construction of our knowledge of the past. Indeed, historians long refused to include literature and films in their historical research, as well as art in general, which has been mainly analysed from an aesthetic point of view.
Arms against a Sea of Troubles: Text and Context of Mikhail Bulgakov’s The White Guard
Authors: Zabirko Oleksandr
Published: November 2020

This article focuses on the representation of historical events in literary texts by pointing at the tension between their factual and fictional elements. The fable and the setting of Mikhail Bulgakov’s novel The White Guard and his novel-based play The Days of the Turbins serve as examples. Almost one hundred years after its first (incomplete) publication, Bulgakov’s novel remains an object of heated debates and is a pivot point for a broad range of current historical, ideological, and cultural clashes between Ukraine and Russia. Against this background, the sophisticated form of Bulgakov’s narratives and the author’s cult status encourage the reader to consider his works both as historical testimonies and poetic prophecies. More importantly, the historical contextualization of The White Guard and The Days of the Turbins goes far beyond their narrated time and the events of the year 1918: it also includes the ideology of smenovekhovstvo, the dramatic changes in Soviet politics of korenizatsiya, and the self-identification of the intelligentsiya in the late Soviet era.

Abstract. During the first phase of the Biomass Burn Operational Project (BBOP) field
campaign, conducted in the Pacific Northwest, the DOE G-1 aircraft was used
to follow the time evolution of wildfire smoke from near the point of
emission to locations 2–3.5 h downwind. In nine flights we made
repeated transects of wildfire plumes at varying downwind distances and
could thereby follow the plume's time evolution. On average there was little
change in dilution-normalized aerosol mass concentration as a function of
downwind distance. This consistency hides a dynamic system in which primary
aerosol particles are evaporating and secondary ones condensing. Organic
aerosol is oxidized as a result. On all transects more than 90 % of
aerosol is organic. In freshly emitted smoke aerosol, NH4+ is
approximately equivalent to NO3. After 2 h of daytime aging, NH4+ increased and is approximately equivalent to
the sum of Cl, SO42, and NO3. Particle size increased with downwind distance,
causing particles to be more efficient scatters. Averaged over nine flights,
mass scattering efficiency (MSE) increased in ∼ 2 h by 56 % and doubled in one flight. Mechanisms for redistributing mass from small to large particles are discussed. Coagulation is effective at moving
aerosol from the Aitken to accumulation modes but yields only a minor increase in MSE. As absorption remained nearly constant with age, the time
evolution of single scatter albedo was controlled by age-dependent
scattering. Near-fire aerosol had a single scatter albedo (SSA) of 0.8–0.9. After 1 to 2 h of aging SSAs were typically 0.9 and greater. Assuming global-average surface and atmospheric conditions, the observed
age dependence in SSA would change the direct radiative effect of a wildfire plume from near zero near the fire to a cooling effect downwind.

Abstract. Ecosystems exchange climate-relevant trace gases with the atmosphere,
including volatile organic compounds (VOCs) that are a small but highly
reactive part of the carbon cycle. VOCs have important ecological functions
and implications for atmospheric chemistry and climate. We measured the
ecosystem-level surface–atmosphere VOC fluxes using the eddy covariance
technique at a shallow subarctic lake and an adjacent graminoid-dominated
fen in northern Sweden during two contrasting periods: the peak growing
season (mid-July) and the senescent period post-growing season
(September–October). In July, the fen was a net source of methanol, acetaldehyde, acetone, dimethyl sulfide,
isoprene, and monoterpenes. All of these VOCs showed a diel cycle of
emission with maxima around noon and isoprene dominated the fluxes (93±22 µmol m−2 d−1, mean ± SE). Isoprene
emission was strongly stimulated by temperature and presented a steeper
response to temperature (Q10=14.5) than that typically assumed in
biogenic emission models, supporting the high temperature sensitivity of
arctic vegetation. In September, net emissions of methanol and isoprene were
drastically reduced, while acetaldehyde and acetone were deposited to the
fen, with rates of up to -6.7±2.8 µmol m−2 d−1 for acetaldehyde. Remarkably, the lake was a sink for acetaldehyde and acetone during both
periods, with average fluxes up to -19±1.3 µmol m−2 d−1 of acetone in July and up to -8.5±2.3 µmol m−2 d−1 of acetaldehyde in September. The deposition of
both carbonyl compounds correlated with their atmospheric mixing ratios,
with deposition velocities of -0.23±0.01 and -0.68±0.03 cm s−1 for acetone and acetaldehyde, respectively. Even though these VOC fluxes represented less than 0.5 % and less than
5 % of the CO2 and CH4 net carbon ecosystem exchange,
respectively, VOCs alter the oxidation capacity of the atmosphere. Thus,
understanding the response of their emissions to climate change is important
for accurate prediction of the future climatic conditions in this rapidly
warming area of the planet.
Development of the drop Freezing Ice Nuclei Counter (FINC),
intercomparison of droplet freezing techniques, and use of soluble
lignin as an atmospheric ice nucleation standard

Published: November 2020

Abstract. Aerosol-cloud interactions, including the ice nucleation of supercooled liquid water droplets caused by ice nucleating particles (INPs) and macromolecules (INMs), are a source of uncertainty in predicting future climate. Because of INPs' and INMs' spatial and temporal heterogeneity in source, number, and composition, predicting their concentration and distribution is a challenge, requiring apt analytical instrumentation. Here, we present the development of our drop Freezing Ice Nucleation Counter (FINC), a droplet freezing technique (DFT), for the quantification of INP and INM concentrations in the immersion freezing mode. FINC's design builds upon previous DFTs and uses an ethanol bath to cool sample aliquots while detecting freezing using a camera. Specifically, FINC uses 288 sample wells of 5–60 μL volume, has a limit of detection of −25.37 ± 0.15 °C with 5 μL, and has an instrument temperature uncertainty of ±0.5 °C. We further conducted freezing control experiments to quantify the non-homogeneous behavior of our developed DFT, including the consideration of eight different sources of contamination. As part of the validation of FINC, an intercomparison campaign was conducted using an NX-illite suspension and an ambient aerosol sample with two other drop-freezing instruments: ETH's DRoplet Ice Nuclei Counter Zurich (DRINCZ) and University of Basel's LED-based ice nucleation detection apparatus (LINDA). We also tabulated an exhaustive list of peer-reviewed DFTs, to which we added our characterized and validated FINC. In addition, we propose herein the use of a water-soluble biopolymer, lignin, as a suitable ice nucleating standard. An ideal INM standard should be inexpensive, accessible, reproducible, unaffected by sample preparation, and consistent across techniques. First, we compare its freezing temperature across different drop-freezing instruments, including on DRINCZ and LINDA, and determine an empirical fit parameter for future drop freezing validations. Second, we show that commercial lignin has a consistent ice nucleating activity across product batches. Third, we demonstrate that the ice nucleating ability of aqueous lignin solutions are stable over time. With these findings, we aim to show that lignin can be used as a good immersion freezing standard in future technique intercomparisons in the field of atmospheric ice nucleation.
Random noise attenuation of sparker seismic oceanography data with machine learning
Authors: Jun Hyunggu , Jou Hyeong-Tae , Kim Chung-Ho , Lee Sang Hoon , Kim Han-Joon
Published: November 2020

Abstract. Seismic oceanography (SO) acquires water column
reflections using controlled source seismology and provides high lateral
resolution that enables the tracking of the thermohaline structure of the
oceans. Most SO studies obtain data using air guns, which can produce
acoustic energy below 100 Hz bandwidth, with vertical resolution of
approximately 10 m or more. For higher-frequency bands, with vertical
resolution ranging from several centimeters to several meters, a smaller,
low-cost seismic exploration system may be used, such as a sparker source
with central frequencies of 250 Hz or higher. However, the sparker source
has a relatively low energy compared to air guns and consequently produces
data with a lower signal-to-noise (S∕N) ratio. To attenuate the random noise
and extract reliable signal from the low S∕N ratio of sparker SO data without
distorting the true shape and amplitude of water column reflections, we
applied machine learning. Specifically, we used a denoising convolutional
neural network (DnCNN) that efficiently suppresses random noise in a natural
image. One of the most important factors of machine learning is the
generation of an appropriate training dataset. We generated two different
training datasets using synthetic and field data. Models trained with the
different training datasets were applied to the test data, and the denoised
results were quantitatively compared. To demonstrate the technique, the
trained models were applied to an SO sparker seismic dataset acquired in the Ulleung Basin, East Sea (Sea of Japan), and the denoised seismic sections were evaluated. The results show
that machine learning can successfully attenuate the random noise in sparker
water column seismic reflection data.

Tais estudos foram obtidos no Portal de Periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes), com os seguintes critérios: artigos publicados nos últimos cinco anos (2014 a 2019), em Língua Portuguesa, em periódicos avaliados por pares, contendo as expressões exatas “desigualdades educacionais” e “Estado”. A análise demonstrou que a falta de uma concepção clara de Estado e de seu papel influencia diretamente sobre a análise dos objetivos da política educacional e de sua implementação.
POLÍTICAS DE PRIVATIZAÇÃO DO ENSINO SUPERIOR BRASILEIRO: UMA ANÁLISE ACERCA DAS ORIENTAÇÕES DO BANCO MUNDIAL.
Authors: Rodrigues Lucas de Paula , Souza Vânia de Fátima Matias de
Published: November 2020

O texto tem como objetivo analisar as relações de similaridades dos imperativos que tratam da privatização do Ensino Superior público brasileiro e as orientações do Banco Mundial. Considerou-se como elementos basilares, os documentos “Um ajuste justo” (2017) e “Gestão de pessoas e folha de pagamentos no setor público brasileiro” (2019). As categorias sustentadas pelos pressupostos da análise de conteúdo elegidas foram: relação público-privado; parcerias; gestão; reajustes e flexibilização. As impressões trazidas nos dois documentos sustentam-se nos imperativos trazidos no formato de “soluções” para o financiamento do ensino superior brasileiro, pautada na diminuição do financiamento público das universidades cujas propostas são postas no formato de reajustes de financiamento do setor público.

Authors: Alves Gabriela Carvalho Mizuno , Teles Graziele Lopes , Santos de S. Hannum Juliana , E Prado Morabi Marina De Moraes
Published: November 2020

As práticas de ações em saúde fazem parte de um projeto de extensão universitária, o Projeto Saúde e Políticas Públicas, pertencente ao Programa de Referência em Inclusão Social (PRIS/CDEX/PROEX) da Pontifícia Universidade Católica de Goiás. Este projeto articula ensino, pesquisa e extensão e tem como objetivo realizar ações educativas e interventivas voltadas para a promoção e prevenção da saúde junto à comunidade acadêmica (voluntários graduandos, graduados e docentes) e à comunidade em geral (equipes de saúde e de educação, crianças, idosos, gestantes e famílias que estão inseridas no contexto das ações aplicadas no projeto). Para tanto, foram realizadas ações em saúde em diversos contextos, dentre eles: as unidades de saúde, de educação infantil e de atenção ao idoso. As ações em questão proporcionaram aos profissionais e aos acadêmicos uma formação humanizada e o diálogo com a comunidade de modo a promover a construção do fazer em saúde.

A boa-fé objetiva como cláusula geral e os pressupostos para a sua aplicação
Authors: Hirata Alessandro , Hernandes Silva Beatriz
Published: November 2020

A boa-fé objetiva por ter sido adotada como cláusula geral no Código Civil de 2002, é entendida de maneira multifacetar, operando com várias funções no ordenamento jurídico brasileiro. Se por um lado, as mudanças do Código Civil proporcionaram maior diálogo com outros princípios contratuais, como o da conservação dos negócios jurídicos, e concederam ao ordenamento jurídico abertura para exigências éticas de conduta, por outro, a indeterminação da cláusula geral relativa à boa-fé levou à compreensão generalista do conceito, ensejando o seu uso indiscriminado, sem que os seus diversos sentidos, ético, econômico, interpretativo e instaurador de deveres às partes, inclusive nas fases pré e pós contratuais, fossem diferenciados. Em virtude disso, necessário se torna o conhecimento e a determinação dos diferentes significados assumidos pela boa-fé objetiva, mediante a adoção de pressupostos de aplicação que orientem o jurista no bom emprego da cláusula geral na resolução do caso concreto.
Debates virtuais sobre subjetividade, sociedade e política na pandemia de COVID-19
Authors: Vieira Érico Douglas
Published: November 2020

A pandemia da Covid-19 trouxe impactos subjetivos e sociais significativos em razão das rupturas, inseguranças geradas e necessidades de reorganizações individual e coletiva. Neste contexto, as universidades propõem diversas ações de enfrentamento a esta crise. Este trabalho é um relato de experiência de um projeto de extensão que teve como objetivo a realização de debates virtuais como possibilidade de reflexões e elaborações de enfrentamentos em relação à crise provocada pela pandemia, articulando subjetividade, sociedade e política. As atividades proporcionaram momentos significativos de aprendizado, reflexões e trocas. As reflexões foram potencializadas pelo esforço didático do palestrante e pela interação entre os participantes através do chat. Houve a formulação de estratégias de enfrentamento e resistência em relação à pandemia, articulado a um desejo de transformação dos aspectos injustos da sociedade brasileira.
Qualidade e Educação a Distância: reflexões e entendimentos
Authors: Maieski Alessandra , Casagrande Ana Lara , Morosov Alonso Kátia
Published: November 2020

Resumo: O presente trabalho visa refletir sobre a qualidade na Educação a Distância (EaD). É parte de uma pesquisa interinstitucional da região Centro-Oeste, da qual participa a Universidade Federal de Mato Grosso. Ao destacar tal conceito, o objetivo é estabelecer entendimentos sobre o mesmo, considerando o contexto da EaD. Para tanto, foi realizado um levantamento bibliográfico, tendo por base as seguintes fontes: Portal de Teses da Europa e do Scopus. Os resultados evidenciam a necessidade de um olhar crítico, devido ao entendimento, nos trabalhos pesquisados, de que a qualidade na educação relacionar-se-ia à oferta de serviço, portanto, na perspectiva do aluno-cliente, o que aproxima a EaD das discussões sobre rentabilidade, afastando-a da compreensão do ensino-aprendizagem como processo formativo. Parte-se do pressuposto, nesta reflexão, de que é necessário maior precisão conceitual em prol de uma EaD condizente com a educação democrática e de qualidade socialmente referenciada.

Leituras cruzadas sobre Cruz e Sousa, poeta órfico (Crítica, narrativa, teatro...)
Authors: Pires Antônio Donizeti
Published: November 2020

O catarinense Cruz e Sousa não é um poeta de vanguarda, formado sob a ruidosa ruptura com o passado. Ao contrário: sua formação é a Modernidade contraditória do século XIX, cuja pluralidade estética é perceptível em seu projeto ético-poético, sobretudo no que concerne ao Simbolismo e ao Decadentismo, que em suas mãos tingem-se de desconcertante originalidade. Este ensaio, partindo da poesia madura de Cruz e Sousa, leitor de Baudelaire & outros, almeja estudar o modo como nosso poeta foi lido por alguns de seus pares, em termos de crítica, narrativa, teatro etc.
O lugar das línguas indígenas e africanas no Museu da Língua Portuguesa
Authors: Mendes Heloisa
Published: November 2020

Neste trabalho, pretendemos analisar, a partir da perspectiva teórica da Análise do Discurso francesa, o discurso sobre as línguas indígenas e africanas no Museu da Língua Portuguesa – instituição localizada na cidade de São Paulo (Brasil), que está sendo reconstruída, depois do incêndio ocorrido em dezembro de 2015. Utilizando os conceitos de cena de enunciação e ethos, são analisados os textos sobre essas línguas no espaço expositivo Palavras Cruzadas. Argumentamos que, ao restringir as línguas indígenas e africanas a certa “influência” no léxico, o museu assume um posicionamento sobre a identidade linguística do Brasil que, simultaneamente, reconhece sua originalidade e a superior unidade da língua portuguesa.

ICT solutions to support local food supply chains during the COVID-19 pandemic
Authors: Mittal Anuj , Grimm Jason
Published: November 2020

The COVID-19 pandemic has disrupted food supply chains operations across the globe. Due to health safety practices like social distancing, local food supply chains such as farmers markets and food hubs are unable to conduct normal operations. This paper describes two low-cost information and communica¬tion technology (ICT) solutions developed for a farmers market and a food hub in Iowa to enable them to continue their operations during the pandemic while ensuring the safety of vulnerable consumers and essential workers. Other benefits of ICT for the long-term sustainability of local food systems are also discussed.
The Saddest Bubbles: Toward a Theory of Outrage
Authors: Gharavi Lance
Published: November 2020

Outrage as a form of discourse has flourished in recent decades, emerging as a social force with formidable and far-reaching consequences. This article argues that outrage is a performance that functions like a religion, its proliferation and power abetted by the structures and designs of certain ubiquitous digital technologies. Outrage operates like Emile Durkheim's concept of religion: it is productive of communities and subjectivities and the moral order that binds them. Borrowing from Durkheim's analysis, this article identifies five social functions of outrage as performance and affect, and analyze the incentives, design elements, and material structures of the technological and social media platforms that foster its spread and amplify its impact.
Christianity on the Taiwanese Traditional Stage: Why “Hallelujah”?
Authors: Stenberg Josh
Published: November 2020

Xiqu (“Chinese opera”) is often associated with religion, but usually not with Christianity. Over the last twenty years, troupes in the Taiwanese genre of gezaixi, funded by Protestant churches, have sought to find new audiences through the performance of bible stories. This article argues that such endeavors, known as “gospel” gezaixi, constitute a conscious effort on the part of Taiwanese Protestants to eliminate the barrier still presumed between Christianity and “local culture.” At the same time, Christian organizations represent an important new source of sponsorship for the genre, whose audience is ageing.
On the Stage, But Not of the Stage: Harriet Beecher Stowe's The Christian Slave and the Advent of Evangelical Theatre in Antebellum America
Authors: D'ambrosi Joseph R.
Published: November 2020

In 1854, Harriet Beecher Stowe adapted a portion of Uncle Tom's Cabin into a one-woman dramatic reading entitled The Christian Slave, despite her clear abhorrence for the theatre and for the unauthorized melodramatic adaptations of her best-selling novel. This article argues that although Stowe outwardly rejected secular theatre practice, her staged reading is a representation of how she engaged with theatre in order to spread her anti-slavery message to a broader audience. This article profiles the actress for whom Stowe wrote the play—a mixed-race woman named Mary E. Webb—and argues that Webb's Black body was a tactic to give Stowe's words an added layer of authenticity. It also illuminates the play's innate use of theatricality and sensation. Not only was Stowe aware of the popular theatrical form of her day, but she engaged with these forms to appeal to an audience outside of her readership, furthering her message of evangelical abolition.
Reckoning with the Autobiography
Authors: Michelson Bruce
Published: November 2020

Although Mark Twain wanted his autobiographical writings and dictations to become a published book and a culminating text in his legacy, the definitive Autobiography of Mark Twain has attracted only cautious attention as yet, because it presents interconnected texts and compels negotiation of complex personal and historical circumstance. These texts include (1) autobiographical discourses beginning in 1904, along with Mark Twain's earlier forays into life-writing; (2) editorial annotations and notes for all these discourses; (3) a detailed history of these efforts; and (4) an account of how and why these documents have been recovered, established, and sequenced. Conjoined here, these texts constitute an important experiment in American life-writing, as well as a challenge to scholarly engagement with this kind of narrative and its implications.
Trollfighting Mark Twain: Viral Media and the Funston Feud
Authors: Seybold Matt
Published: November 2020

Fred Funston, an alleged hero of the Philippine-American War, was enjoying a fleeting celebrity, including rumors of becoming President Theodore Roosevelt's running mate. Using only a satiric essay in the North American Review, “A Defense of General Funston,” and a letter to the editor of the Denver Post, near where Funston was then stationed, Mark Twain generated a controversy that lasted for months, was covered by many newspapers throughout the continental United States, and succeeded in destroying Funston's reputation. This relatively minor episode in Twain's life reveals not only how he was able to leverage his celebrity and manipulate the US mass media during the final decade of his life, but also how the mass media environment, which had continually expanded and diversified over the course of the nineteenth century, had become a site of cultural power.
