Dramas televisivos de prestígio e masculinidade
Authors: Castellano Mayka , Meimaridis Melina , Ferreirinho Gabriel
Published: December 2021

O artigo analisa as controvérsias de gênero ligadas à discussão sobre “qualidade televisiva” e “dramas de prestígio” em séries americanas. A categoria “TV de qualidade” já sofreu inúmeras mudanças, porém, indicamos como significativa a predominância de obras criadas por homens, com protagonistas masculinos e que possuem códigos pertencentes ao universo da masculinidade hegemônica apontadas como paradigmáticas do atual bom momento vivido pela televisão estadunidense. Partimos do pressuposto de que é no mínimo problemática a associação de ideias como “complexidade”, “qualidade” e “prestígio” com a representação da masculinidade hegemônica em produtos televisivos populares.

Comunicação e Identidade organizacional da Igreja Adventista do Sétimo Dia: estudo de Manual de Gestão de Crise e da relação de sentido em duas repercussões na mídia
Authors: Lemos Felipe Diemer de , Dravet Florence Marie , Iasbeck Luiz Carlos de Assis , Dias Robson
Published: December 2021

o artigo exploratório analisa a tensão existente entre os conceitos de identidade organizacional (IASBECK, 1997) e comunicação em situações de crise e um dos resultantes desta relação, que é a possibilidade de ressignificação da própria identidade da organização. Isso é mostrado a partir da perspectiva da gestão de crise no contexto desenvolvido por uma organização religiosa, a saber, a Igreja Adventista do Sétimo Dia no Brasil, utilizando o conceito de irritações de Luhmann (2010). Para tanto, a análise empírica é feita em duas fontes de evidências: análise do Manual de Crise da instituição (1) e repercussão na mídia de duas crises no contexto da disputa de sentidos (2). Resultados desta análise empírica procuram evidenciar a relação direta entre o processo de gerenciamento da crise e a maneira como este processo pode conduzir a contribuições para a identidade da organização. A crise, por isso, conceitualmente vai além da ideia apenas de um problema, mas de uma oportunidade de ressignificação.

Published: December 2021

The refraction of fluorescence from the inside of a sample at the surface results in fluctuations in fluorescence computed tomography (CT). We evaluated the influence of the difference in refractive index (RI) between the sample body and the surroundings on fluorescence CT results. The brightest fluorescent point is away from the correct point on the tomograms owing to the refraction. The speculated position is determined as the exact point if the RI ratio ranges between 0.97 and 1.03 by immersing the body in an RI matching liquid. The results can help in experimental settings of fluorescence CT for acquiring three-dimensional positional information.
Observation of mode-mixing in the spatial eigenmodes of an optical microcavity
Authors: Koks C. , van Exter M. P.
Published: December 2021

We present a method to determine the complex coupling parameter of a two-coupled-modes system by directly measuring the coupled eigenmodes rather than their eigenvalues. This method is useful because mode-mixing can be observed even if frequency shifts can not be measured. It also allows to determine the complex coupling parameter, from which we conclude that the observed coupling is mainly conservative. We observe mode-mixing in an optical microcavity, where the modes couple primarily at the mirror surface, as confirmed by AFM measurements. The presented method is general and can be applied to other systems to measure mode coupling more accurately and to determine the nature of the coupling.
Selective excitation of different combinations of LP01 and LP11 polarization modes in a birefringent optical fiber using a Wollaston prism
Authors: Zolnacz Kinga , Urbanczyk Waclaw
Published: December 2021

We present an effective method for free-space selective excitation of different combinations of LP01 and LP11 polarization modes in a birefringent optical fiber using a Wollaston prism, rotatable polarizer, and achromatic half-wave plate. The method is minimally wavelength-dependent and can be used for high-power sources. The relative coupling efficiencies of different modes can be continuously tuned and the suppression rate of the unwanted modes with respect to the targeted mode exceeds 20 dB. We present input system configurations that allow for the excitation of different individual modes and groups of modes and estimate the maximum coupling efficiencies based on numerical simulations. As example applications, we show the generation of Raman sidebands in different modes, gain tunability of intermodal four-wave mixing, and broadband conversion of a supercontinuum light beam from the fundamental to the LP11 mode.
Quantum theory of nonradiative decay dependent on the coupling strength in a plexcitonic system
Authors: Huang Yuming , Wang Yilin , Liang Kun , Yu Li
Published: December 2021

Revealing the quantum dynamics of plexciton, hybridized states produced by a quantum emitter and localized surface plasmon (LSP) in a strong coupling regime is of importance from fundamental and applied points of view. Photoluminescence (PL) spectrum is recognized for essentially reflecting the interaction between light and matter compared with extinction spectrum and scattering spectrum. However, there are still challenges to realize single-emitter plexciton in PL spectrum because of the unexpected nonradiative decay. In this paper, we develop a full-quantum method to describe the interaction between single emitter and a plasmonic nanocavity. By utilizing our model, we find that there is an optimum for surface-fluorescence enhancement near an intermediate coupling regime instead of a strong coupling regime. Furthermore, we show that strong electric-field enhancement will broaden plexciton’s linewidth covering the Rabi splitting in PL spectrum. The relation between nonradiative decay and coupling strength is given by a quantitative method, and we obtain the revised equation for PL spectrum. By comparing the revised PL spectrum with the scattering spectrum, we find that it is best to find optimal fluorescence splitting in the critical point between the intermediate coupling regime and strong coupling regime. Our method provides a theoretical method for explaining the nonradiative decay depending on coupling strength of a plexcitonic system in the PL spectrum and revealing single-emitter quantum optics.

Published: December 2021

Thanks to the large time bandwidth product (TBWP), linearly chirped microwave waveforms (LCMWs) are widely used in modern radar systems to achieve high-resolution detection and imaging. To overcome the challenge of small unmanned aerial vehicle detection and tracking, radar systems are required to have a higher resolution and multi-function operation, in which an ultra-wideband LCMW is highly preferred with a flexible tuning in the center frequency, instantaneous bandwidth, and multi-band operation. In this paper, we propose and experimentally demonstrate an approach to generating flexible ultra-wide LCMWs based on a Fourier-domain mode-locked optoelectronic oscillator (FDML-OEO) incorporating a dual-polarization quadrature phase-shift keying (DP-QPSK) modulator. In the DP-QPSK modulator, two dual-parallel Mach-Zehnder modulators (DP-MZMs) are integrated. With the use of the upper DP-MZM, an FDML-OEO is produced to generate a wideband LCMW with a tuning in the center frequency and instantaneous bandwidth. With the injection of the generated LCMW into the lower DP-MZM, an ultra-wideband LCMW is generated via microwave frequency multiplication, and multi-band waveform generation is enabled by controlling the bias condition of the lower DP-MZM. An experiment is performed and an LCMW with a maximum bandwidth as broad as 10.8 GHz is generated. By adjusting the driving signal applied to the FDML-OEO, the generated LCMW can be tuned in the center frequency from 16.2 to 23.2 GHz and the bandwidth from 3.6 to 10.8 GHz. By controlling the bias point of the lower DP-MZM, a dual-band LCMW is also experimentally demonstrated. Thanks to the ultra-wide bandwidth and strong flexibility of the generated LCMWs in terms of tunable center frequency, instantaneous bandwidth and multiband operation, the proposed approach offers a promising LCMW generator in the next-generation high-resolution radar systems.

Published: December 2021

Reconfigurable photonic devices are important constituents for future optical integrated circuits, where electro-optic manipulation of the light field in a lithium niobate (LN) waveguide is one of the promising solutions. Herein, we demonstrate a paradigm shift of the beam steering mechanism where reconfigurable beam steering is enabled by the wavefront shaping technology. Furthermore, this strategy is fully compatible with the electro-optic tuning mechanism of the LN multimode waveguide, where microstructured serrated array electrodes are employed to fine tune the output beam upon its reconfigurable output position. Our results provide new, to the best of our knowledge, insight for molding the flow of light in multimode waveguides and shed new light on beam steering photonic devices.
Autonomous epithelial folding induced by an intracellular mechano–polarity feedback loop

Published: December 2021

Epithelial tissues form folded structures during embryonic development and organogenesis. Whereas substantial efforts have been devoted to identifying mechanical and biochemical mechanisms that induce folding, whether and how their interplay synergistically shapes epithelial folds remains poorly understood. Here we propose a mechano–biochemical model for dorsal fold formation in the early Drosophila embryo, an epithelial folding event induced by shifts of cell polarity. Based on experimentally observed apical domain homeostasis, we couple cell mechanics to polarity and find that mechanical changes following the initial polarity shifts alter cell geometry, which in turn influences the reaction-diffusion of polarity proteins, thus forming a feedback loop between cell mechanics and polarity. This model can induce spontaneous fold formation in silico, recapitulate polarity and shape changes observed in vivo, and confer robustness to tissue shape change against small fluctuations in mechanics and polarity. These findings reveal emergent properties of a developing epithelium under control of intracellular mechano–polarity coupling.
Paradoxical relationship between speed and accuracy in olfactory figure-background segregation

Published: December 2021

In natural settings, many stimuli impinge on our sensory organs simultaneously. Parsing these sensory stimuli into perceptual objects is a fundamental task faced by all sensory systems. Similar to other sensory modalities, increased odor backgrounds decrease the detectability of target odors by the olfactory system. The mechanisms by which background odors interfere with the detection and identification of target odors are unknown. Here we utilized the framework of the Drift Diffusion Model (DDM) to consider possible interference mechanisms in an odor detection task. We first considered pure effects of background odors on either signal or noise in the decision-making dynamics and showed that these produce different predictions about decision accuracy and speed. To test these predictions, we trained mice to detect target odors that are embedded in random background mixtures in a two-alternative choice task. In this task, the inter-trial interval was independent of behavioral reaction times to avoid motivating rapid responses. We found that increased backgrounds reduce mouse performance but paradoxically also decrease reaction times, suggesting that noise in the decision making process is increased by backgrounds. We further assessed the contributions of background effects on both noise and signal by fitting the DDM to the behavioral data. The models showed that background odors affect both the signal and the noise, but that the paradoxical relationship between trial difficulty and reaction time is caused by the added noise.
What makes a histone variant a variant: Changing H2A to become H2A.Z

Published: December 2021

Chromatin structure and underlying DNA accessibility is modulated by the incorporation of histone variants. H2A.Z, a variant of the H2A core histone family, plays a distinct and essential role in a diverse set of biological functions including gene regulation and maintenance of heterochromatin-euchromatin boundaries. Although it is currently unclear how the replacement of H2A with H2A.Z can regulate gene expression, the variance in their amino acid sequence likely contributes to their functional differences. To tease apart regions of H2A.Z that confer its unique identity, a set of plasmids expressing H2A-H2A.Z hybrids from the native H2A.Z promoter were examined for their ability to recapitulate H2A.Z function. First, we found that the H2A.Z M6 region was necessary and sufficient for interaction with the SWR1-C chromatin remodeler. Remarkably, the combination of only 9 amino acid changes, the H2A.Z M6 region, K79 and L81 (two amino acids in the α2-helix), were sufficient to fully rescue growth phenotypes of the htz1Δ mutant. Furthermore, combining three unique H2A.Z regions (K79 and L81, M6, C-terminal tail) was sufficient for expression of H2A.Z-dependent heterochromatin-proximal genes and GAL1 derepression. Surprisingly, hybrid constructs that restored the transcription of H2A.Z-dependent genes, did not fully recapitulate patterns of H2A.Z-specific enrichment at the tested loci. This suggested that H2A.Z function in transcription regulation may be at least partially independent of its specific localization in chromatin. Together, this work has identified three regions that can confer specific H2A.Z-identity to replicative H2A, furthering our understanding of what makes a histone variant a variant.

Mammalian cells release different types of vesicles, collectively termed extracellular vesicles (EVs). EVs contain cellular microRNAs (miRNAs) with an apparent potential to deliver their miRNA cargo to recipient cells to affect the stability of individual mRNAs and the cells’ transcriptome. The extent to which miRNAs are exported via the EV route and whether they contribute to cell-cell communication are controversial. To address these issues, we defined multiple properties of EVs and analyzed their capacity to deliver packaged miRNAs into target cells to exert biological functions. We applied well-defined approaches to produce and characterize purified EVs with or without specific viral miRNAs. We found that only a small fraction of EVs carried miRNAs. EVs readily bound to different target cell types, but EVs did not fuse detectably with cellular membranes to deliver their cargo. We engineered EVs to be fusogenic and document their capacity to deliver functional messenger RNAs. Engineered fusogenic EVs, however, did not detectably alter the functionality of cells exposed to miRNA-carrying EVs. These results suggest that EV-borne miRNAs do not act as effectors of cell-to-cell communication.

Arboviral diseases transmitted by Aedes species mosquitoes pose an increasing public health challenge in tropical regions. Wolbachia-mediated population suppression (Wolbachia suppression) is a vector control method used to reduce Aedes mosquito populations by introducing male mosquitoes infected with Wolbachia, a naturally occurring endosymbiotic bacterium. When Wolbachia-infected male mosquitoes mate with female wild mosquitoes, the resulting eggs will not hatch. Public support is vital to the successful implementation and sustainability of vector control interventions. Communities Organized to Prevent Arboviruses (COPA) is a cohort study to determine the incidence of arboviral disease in Ponce, Puerto Rico and evaluate vector control methods. Focus groups were conducted with residents of COPA communities to gather their opinion on vector control methods; during 2018–2019, adult COPA participants were interviewed regarding their views on Wolbachia suppression; and a follow-up questionnaire was conducted among a subset of participants and non-participants residing in COPA communities. We analyzed factors associated with support for this method. Among 1,528 participants in the baseline survey, median age was 37 years and 63% were female. A total of 1,032 (68%) respondents supported Wolbachia suppression. Respondents with an income of $40,000 or more were 1.34 times as likely [95% CI: 1.03, 1.37] to support Wolbachia suppression than those who earned less than $40,000 annually. Respondents who reported repellant use were 1.19 times as likely to support Wolbachia suppression [95% CI: 1.03, 1.37]. A follow-up survey in 2020 showed that most COPA participants (86%) and non-participants living in COPA communities (84%) supported Wolbachia suppression during and after an educational campaign. The most frequent questions regarding this method were related to its impact on human and animal health, and the environment. Continuous community engagement and education efforts before and during the implementation of novel vector control interventions are necessary to increase and maintain community support.

Published: December 2021

Background

Left ventricular systolic dysfunction (LVSD) in Chagas disease (ChD) is relatively common and its treatment using low-cost drugs can improve symptoms and reduce mortality. Recently, an artificial intelligence (AI)-enabled ECG algorithm showed excellent accuracy to detect LVSD in a general population, but its accuracy in ChD has not been tested.

Objective

To analyze the ability of AI to recognize LVSD in patients with ChD, defined as a left ventricular ejection fraction determined by the Echocardiogram ≤ 40%.

Methodology/principal findings

This is a cross-sectional study of ECG obtained from a large cohort of patients with ChD named São Paulo-Minas Gerais Tropical Medicine Research Center (SaMi-Trop) Study. The digital ECGs of the participants were submitted to the analysis of the trained machine to detect LVSD. The diagnostic performance of the AI-enabled ECG to detect LVSD was tested using an echocardiogram as the gold standard to detect LVSD, defined as an ejection fraction <40%. The model was enriched with NT-proBNP plasma levels, male sex, and QRS ≥ 120ms.

Among the 1,304 participants of this study, 67% were women, median age of 60; there were 93 (7.1%) individuals with LVSD. Most patients had major ECG abnormalities (59.5%). The AI algorithm identified LVSD among ChD patients with an odds ratio of 63.3 (95% CI 32.3–128.9), a sensitivity of 73%, a specificity of 83%, an overall accuracy of 83%, and a negative predictive value of 97%; the AUC was 0.839. The model adjusted for the male sex and QRS ≥ 120ms improved the AUC to 0.859. The model adjusted for the male sex and elevated NT-proBNP had a higher accuracy of 0.89 and an AUC of 0.874.

Conclusion

The AI analysis of the ECG of Chagas disease patients can be transformed into a powerful tool for the recognition of LVSD.

Published: December 2021

Background

Hump-nosed pit viper (HNV;Hypnalespp.) bites account for most venomous snakebites in Sri Lanka. Acute kidney injury (AKI) is the most serious systemic manifestation (1–10%) following HNV envenoming. We aimed to identify the value of functional and injury biomarkers in predicting the development of AKI early following HNV bites.

Methods

We conducted a prospective cohort study of patients with confirmed HNV envenoming presenting to two large tertiary care hospitals in Sri Lanka. Demographics, bite details, clinical effects, complications and treatment data were collected prospectively. Blood and urine samples were collected from patients for coagulation and renal biomarker assays on admission, at 0-4h, 4-8h, 8-16h and 16-24h post-bite and daily until discharge. Follow-up samples were obtained 1 and 3 months post-discharge. Creatinine (sCr) and Cystatin C (sCysC) were measured in serum and kidney injury molecule-1 (uKIM-1), clusterin (uClu), albumin (uAlb), β2-microglobulin (uβ2M), cystatin C (uCysC), neutrophil gelatinase associated lipocalin (uNGAL), osteopontin (uOPN) and trefoil factor-3 (uTFF-3) were measured in urine. Definite HNV bites were based on serum venom specific enzyme immunoassay. Kidney Disease: Improving Global Outcomes (KDIGO) criteria were used to stage AKI. Two patients had chronic kidney disease at 3 month follow-up, both with pre-existing abnormal sCr, and one developed AKI following HNV envenoming.

Results

There were 52 patients with confirmed HNV envenoming; median age 48y (Interquartile range [IQR]:40-59y) and 29 (56%) were male. Median time to admission was 1.87h (IQR:1–2.75h). Twelve patients (23%) developed AKI (AKI stage 1 = 7, AKI stage 2 = 1, AKI stage 3 = 4). Levels of five novel biomarkers, the functional marker serum Cystatin C and the damage markers urinary NGAL, cystatin C, β2-microglobulin and clusterin, were elevated in patients who developed moderate/severe acute kidney injury. sCysC performed the best at 0–4 h post-bite in predicting moderate to severe AKI (AUC-ROC 0.95;95%CI:0.85–1.0) and no biomarker performed better than sCr at later time points.

Conclusions

sCysC appears to be a better marker than sCr for early prediction of moderate to severe AKI following HNV envenoming.
Woman authorship in pre-print versus peer-reviewed oral health-related publications: A two-year observational study
Authors: Rajendran Lavanya , Khandelwal Namita , Feine Jocelyne , Ioannidou Effie
Published: December 2021

Objectives

Women in oral health science face similar societal issues and challenges as those in other STEMM careers, and gender disparities continue to exist as evidenced by fewer women represented as first and last authors in scientific publications. Pre-prints may serve as a conduit to immediately disseminating one’s work, bypassing the arduous peer review process and its associated inherent biases. Therefore, the purpose of this study was to 1] compare the gender of first and last authors in pre-print versus peer reviewed publications, 2] examine the composition of first and last author pairs as stratified by publication type, and 3] examine the correlation between woman authorship and institutional geographic location and publication metrics stratified by publication type.

Methods

The keyword “oral health” was used to search for publications in BioRxiv and Pubmed in the years 2018 and 2019. Gender of first and last authors were determined, and its frequency was considered as the primary outcome. Additionally, the geographic location of the author’s associated institution and publication metrics measured by Altmetrics score were extracted. Data was descriptively summarized by frequencies and percentages. Chi-square analysis was conducted for categorical variables which included the relationship between gender and publication type as well as gender and region of author’s associated institution. Binomial regression analysis was conducted to analyze the relationship between gender and Altmetrics.

Results

Woman first authors comprised 40.3% of pre-prints and 64.5% of peer reviewed publications [p<0.05]. Woman last authors comprised 31.3% of pre-prints and 61.5% of peer reviewed publications [p<0.05]. When analyzing the relationships between first and last author, the Man-Man pairing represented 47.7% of the pre-print publications and the Woman-Woman pairing comprised a majority of the of the peer review publications at 47.5%. All results were statistically significant with a p-value <0.05. No significant correlation was found between region of institution or Altmetrics and gender of first or last authors [p>0.05].

Conclusion

For the first time in oral health science, it was found that women show higher representation as first and last author positions in peer reviewed publications versus pre-prints.
Exploring the green development path of the Yangtze River Economic Belt using the entropy weight method and fuzzy-set qualitative comparative analysis
Authors: Yan Haijuan , Hu Xiaofei , Wu Dawei , Zhang Jianing
Published: December 2021

Green development is an effective way to achieve economic growth and social development in a harmonious, sustainable, and efficient manner. Although the Yangtze River Economic Belt (YREB) plays an important strategic role in China, our understanding of its spatiotemporal characteristics, as well as the multiple factors affecting its green development level (GDL), remains limited. This study used the entropy weight method (EWM) to analyze the temporal evolution and spatial differentiation characteristics of the GDL in the YREB from 2011 to 2019. Further, fuzzy-set qualitative comparative analysis (fsQCA) was used to analyze the influence path of GDL. The results showed that the GDL of the YREB increased from 2015 to 2019, but the overall level was still not high, with high GDL mainly concentrated in the lower reaches. The GDL model changed from being environmentally driven and government supported in 2011 to being environmentally and economically driven since 2014. The core conditions for high GDL changed from economic development level (EDL) to scientific technological innovation level (STIL) and environmental regulation (ER). The path for improving GDL is as follows: In regions with high EDL, effective ER, moderate openness level (OL), and high STIL are the basis, supplemented by a reasonable urbanization scale (US). In areas with low EDL, reasonable industrial structure (IS) and STIL are the core conditions for development; further, EDL should be improved and effective ER and OL implemented. Alternatively, without considering changes to EDL, improvement can be achieved through reasonable OL and US or effective ER. This study provides a new method for exploring the path of GDL and a reference for governments to effectively adjust green development policies.
Appropriating the abject: Witchcraft in Dario Argento and Daria Nicolodi’s Suspiria (1977) and David Kajganich and Luca Guadagnino’s 2018 remake
Authors: Davies Luke Lewin
Published: December 2021

This article explores representations of witchcraft in relation to Julia Kristeva’s 1980 essay Powers of Horror. It begins by investigating the genesis of Dario Argento and Daria Nicolodi’s depiction of witchcraft in their 1977 horror film Suspiria, drawing on historical studies of witchcraft by Ronald Hutton and Marion Gibson. In particular, it examines the characterization of the witches’ coven as an all-female, all-powerful death cult – before proposing that Kristeva’s essay on the abject can be seen to explain this specific conceptualization, in line with Barbara Creed’s analysis of how horror film has inherited the role of ‘purifying’ the abject from religious ritual. The second half of this article then focuses on David Kajganich and Luca remake of Suspiria, reflecting on how the later film can be seen to attempt to redeem the association between witchcraft and abjectness. In doing so, this article reflects on how the attempt to rescue the witch while maintaining an association with the abject is contiguous with other contemporary depictions of witchcraft. It is proposed that such efforts amount to a Foucauldian attempt at a ‘reverse discourse’ celebrating the subversive potential of an initially derogatory identity formation – but that Kristeva’s writing points to the limitations of appropriating the abject in this way.
A indústria portuguesa pelo olhar da fotografia na viragem do século XIX para o século XX
Authors: Pereira Hugo Silveira
Published: December 2021

No período entre o último quartel do século XIX e primeiros anos do século XX coincidiram em Portugal três processos históricos diferenciados, mas conexos: um modesto crescimento industrial, a disseminação da fotografia como prática corrente e a publicação de imagens fotográficas na imprensa ilustrada. Este artigo analisa o modo como uma revista ilustrada, O Occidente, representou a indústria portuguesa, através da publicação de fotografias ou gravuras de fotografias. Seguindo uma metodologia que combina semiótica com análise de conteúdo em fotojornalismo, este estudo mostra que O Occidente criou uma ideia da indústria nacional como um setor moderno, inovador e prova do progresso português, que não coincidia com a sua verdadeira realidade. Este artigo contribui para o debate académico sobre a importância da fotografia como fonte histórica (e não apenas como instrumento ilustrativo) e para história empresarial, nomeadamente as representações que se criavam e disseminavam sobre a indústria portuguesa.

Published: December 2021

O século XIX constitui-se como um marco na história da imprensa feminina portuguesa. Datam deste período as primeiras colaborações femininas em periódicos, assim como a criação dos primeiros jornais destinados e dirigidos por mulheres, como é o caso de A Assembléa Litteraria e de A Voz Feminina, que se constituem como dois periódicos pioneiros na luta pela causa feminina. Neste sentido, no presente artigo é nosso objetivo analisar as vozes das mulheres presentes na imprensa oitocentista, especificamente nos jornais anteriormente mencionados, que se constituem como uma fonte inestimável de informação acerca da mentalidade da época. Destacaremos as ideias destas mulheres em favor do seu sexo e do acesso a direitos fundamentais, como a instrução, chave para a emancipação intelectual do sexo feminino. Para levar a cabo esta investigação, foram consultadas fontes bibliográficas e hemerográficas.
A Cooperativa Indústria Social
Authors: Carvalho João Lázaro
Published: December 2021

Neste artigo pretendemos analisar a cooperativa Indústria Social, uma experiência coletiva no mundo operário português, que despontou de um amplo movimento grevista realizado entre 1872 e 1873. Durante décadas a cooperativa Indústria Social foi um estabelecimento fabril do sector do ferro com grande relevo na História do Trabalho. Recorrendo à imprensa da época, à correspondência dos socialistas e ao inquérito industrial de 1881, abordamos a origem da fábrica, o modelo de gestão, o património industrial, a produção, as condições de trabalho e, não menos importante, o que esta experiência representava como sinal da chegada de novos tempos na indústria e na sociedade portuguesa. O texto aprofunda a influência e as ligações entre o movimento operário e a fábrica.
Rádio Clube de Moçambique
Authors: Freitas Marco
Published: December 2021

O Rádio Clube de Moçambique (RCM) foi uma empresa de radiodifusão privada sedeada em Lourenço Marques (atual Maputo) que granjeou uma forte expansão após a II Guerra Mundial, tornando-se numa das mais importantes instituições de radiodifusão comercial em África. Partindo da análise de publicações periódicas, relatórios de contas, entrevistas e outra documentação-áudio consultada nos arquivos da instituição, com este artigo pretende-se construir uma história do RCM desde a data da sua fundação, em 1932, até ao golpe de Estado em abril de 1974 na metrópole. Terei como ponto de partida os conceitos «rádio-colonização» e «capitalismo sonoro», com vista a explorar a instrumentalização dos sistemas de radiodifusão para propósitos políticos e propagandísticos. Este artigo incidirá, entre outros fatores, nas dimensões económicas, materiais e culturais desta instituição, sem descurar a análise da programação radiofónica.

O comércio de especiarias entre Portugal e a Índia despertou o interesse de diferentes reinos europeus, levando a expedições ultramarinas rivais, ao mesmo tempo que fez com que os navios portugueses vindos da Ásia fossem um alvo bastante apetecível para corsários e piratas, sendo que, na primeira metade do século XVI, destacaram-se as investidas francesas. Para fazer face a essas situações, e ao mesmo tempo que eram mobilizadas armadas para protegerem a navegação portuguesa, foi-se desenvolvendo uma rede de espionagem a fim de captar informação que pudesse antecipar as intenções francesas, fosse no que diz respeito à elaboração de expedições ultramarinas como de ataques navais. Neste estudo penetraremos nos meandros dessa rede de espionagem, tentando compreender como é que funcionava e de que modo Portugal recebia informações para poder atuar em conformidade com as diferentes situações.
A crise económica em Penafiel nos inícios do século XIX pelos livros das décimas de 1800, 1813 e 1821
Authors: Barbosa José Luís
Published: December 2021

Nos inícios do séc. XIX, Penafiel viveu um período de crise económica, agravada pela conjuntura da Guerra Peninsular e da instabilidade que se seguiu, até à Revolução Liberal. Neste estudo pretendemos analisar o impacto desta crise em Penafiel, com base nos livros das décimas da cidade, relativos aos anos de 1800, 1813 e 1821. Com vista a tal objetivo, esta investigação apresenta três eixos principais de análise: o estudo da décima do maneio enquanto indicador da atividade económica; a análise da décima dos juros e a evolução do mercado creditício; e a aferição da desigualdade nos rendimentos dos penafidelenses, por intermédio do coeficiente de Gini. A análise dos dados terá uma componente comparativa com outras localidades portuguesas.
Az átjárhatóság fogalmának jelentésrétegei Frenák Pál művészetében
Authors: Horváth Nóra
Published: December 2021

A híres magyar tánckoreográfus, Frenák Pál művészi világát kívánom bemutatni, aki negyven éve szoros spirituális kapcsolatban van Gilles Deleuze francia filozófus műveivel, és gyakran a művészetről is deleuze-i fogalmakban gondolkodik, ugyanakkor nem használ konkrét szövegreferenciákat a munkáiban. Az átjárhatóság esztétikai és etikai kritériummá vált az alkotásaiban, melynek szükségességét gyakran megemlíti. Frenák a kortárs táncélet egyik legizgalmasabb koreográfusa, aki a siketek és nagyothallók jelrendszerének energiáiból építkezve egy új és egyedi (organikus) mozgásnyelvet hozott létre.
Lokális kulturális elemek diffúziója a Római Birodalomban
Authors: Újvári Edit
Published: December 2021

A tanulmány a globalizáció és a helyi kultúrák viszonyának egy kultúrtörténeti példáját mutatja be, az egyiptomi vallási jelenségek elterjedését a Római Birodalomban, a pannoniai Savariában. Az európai kultúrának máig meghatározó alapja az ókori római kultúra, amelynek számos kulturális öröksége között az „interpretatio Romana” jelensége a konferenciakötet témája szempontjából kimondottan tanulságos. Ezt a kultúr- és vallástörténeti jelenséget megvizsgálva arra keresem a választ, hogy az ókori Mediterráneum népeit birodalmi egységbe vonó/kényszerítő Róma valláspolitikájának toleráns vonatkozásai hogyan eredményezték a lokális kulturális elemek birodalmi, „globalizált” változatainak létrejöttét, a különböző népcsoportok helyi kulturális hagyományainak elterjedését. Milyen vonásokkal rendelkezett az egyiptomi eredetű kultusz a mai Szombathely területén, a római Savaria Iseumában?

Ezekkel a dinamikusan változó a kihívásokkal kell megbirkózniuk a szülőknek, miközben az ő életükön, és gondolkodásukon is folyamatosan nyomot hagy a digitális világ
Kreativitás, digitális identitás és mitológia
Authors: Dergez-Rippl Dóra
Published: December 2021

Digitális életterünk szociokulturális lehetőségei nagyrészt megegyeznek eddigi, predigitális lehetőségeinkkel. Miért idegenkedünk mégis ettől a közegtől, miért látjuk veszélyben identitásunkat, kapcsolatainkat és kulturális értékeinket? A kérdést az identitás, kreativitás és mitológia fogalmainak segítségével metaelméleti szempontból vizsgálom, és az evolúciós magyarázatokat („aki kimarad, lemarad”, illetve „az marad életben, aki leginkább fogékony a változásra”) olyan értelmezési lehetőségekkel egészítem ki, mint a szimbólumokon alapuló tudásrendszereink extraszomatikus jellege, identitásunk digitális reprezentációjának kognitív alapja, a mitológia paradox karaktere, vagy a komplex gondolkodáson alapuló kreativitás személyiségfejlesztő (egyéni) és hagyományőrző (szociális) jelentősége.
Tágas lokalitás, szűk világ – Weimari konzervatív forradalomkritikák
Authors: Tőke Márton
Published: December 2021

A tanulmány három weimari emigráns, Hermann Rauschning, Leo Strauss és Henry Kissinger forradalomkritikai meglátásain keresztül tárgyalja azt az eszmei sokszínűséget, ami a közvélekedéssel szemben jellemezte a nemzetiszocialista hatalomátvételt követő menekülők gondolatiságát. Először is a tágas lokalitás fogalmával festi fel a weimari emigráns alakját, mint fogalmi keretet, meghatározva annak fő jellemzőit. Ezután a három említett szerzőnek a nihilizmusról és a forradalmi viselkedésről alkotott nézeteit, ezek kapcsolódási pontjait és eltéréseit vizsgálja, igyekezve ezeken keresztül bemutatni többfajta konzervatív pozíciót, kitérve ezek későbbi hatására, globális jelentőségére is.

Published: December 2021

Studies based on a biogenic synthesis of noble metal nanomaterials has become a promising one in
today’s biomedical approach in therapy and diagnosis due to multidimensional applications. Hence,
the present study is to explore the antibacterial, antibreast cancer and photocatalytic efficacy of silver
nanoparticles (AgNPs) synthesized from an extract of Beta vulgaris (BV). The band at 398 nm in the
UV-visible spectra confirmed the formation of AgNPs. The characteristic shift in OH and C=O peak
after the formation of silver nanoparticles shows the participation of Beta vulgaris extracts in the
reduction process which is further supported by from SEM morphology. The average size of the
particle (17 nm) was determined from XRD analysis using Scherrer’s equation. Antibacterial results
of Beta vulgaris mediated BV-AgNPs show the maximum zone of inhibition against Candida albicans.
On anticancer activity, BV-AgNPs reveals the toxicity effect on the MCF-7 cell line with an IC50 value
of 40.65 μg/mL. Similarly, it reduces 81.3% of methyl orange at 180 min on the photocatalytic reduction
process. This study has suggested an effective replacement for the hazardous chemical methods and
leads to a cost-effective, environmentally-friendly method that can also be used as antibacterial and
anticancer agents.

Published: December 2021

Organically functionalized manganese doped zinc sulfide (ZnS/Mn) quantum dots were prepared by
simple chemical method with polypyrrole (PPy) used as a capping agent. Prepared quantum dots were
characterized with Fourier transform infrared spectroscopy (FTIR), high resolution transmission electron
microscopy (HR-TEM), X-ray diffraction microscope (XRD), UV-visible spectroscopy and
photoluminescence spectroscopy. Crystalline size of PPy capped ZnS/Mn quantum dots for various
concentrations of PPy were approximate 2 nm as analyzed by XRD and TEM analysis. The absorption
spectra revealed the occurrence of a blue shift in the peak of absorption and an increase in the band
gap value due to the quantum confinement effect. FTIR spectroscopy confirmed that shifting of broad
peak at 2335.8 cm–1 was due to S-H stretching vibrations, which confirmed interaction of hydrogen
and sulphur in ZnS/Mn/PPy nanocomposites. Uncapped ZnS/Mn and PPy capped ZnS/Mn quantum
dots reveal the effective photoluminescence emission spectra in the range of 300-700 nm. With increase
the value of capping agent in ZnS/Mn quantum dots, photoluminescence spectra going to red shifting.
The photoluminescence properties of the organically functionalized ZnS nanoparticles are favourable
for the application in optoelectronic devices.

Published: December 2021

A novel series of trivalent coordination complexes was synthesized by the reaction between a chloride/
acetate salt of iron, chromium, cobalt or manganese ions and NNNNOO type persuasive Schiff base
ligand synthesized from 2,3-dioxobutane, ethane-1,2-diamine and 4-chloro-2-formylphenol.
Synthesized compounds were characterized by using elemental analysis, molar conductance, magnetic
moment, IR, UV-visible, 1H NMR, 13C NMR and ESI-MS spectral analyses. IR and NMR spectra
favoured hexadentate coordination behaviour of ligand. Electronic spectra and magnetic moment data
reveal Oh geometry with distortion around the metal ion in complexes. The molar conductance values
show 1:1 electrolytic nature of complexes. Biological potentiality of the ligand and its metal complexes
were tested in vitro against two bacterial and two fungal strains; Bacillus subtilis, Escherichia coli and
Aspirgillus niger, Aspirgillus flavus, respectively.
