Verbal and Visual Components of the Screen Texts (Case Study of Film And Teletexts)
Authors: Evgrafova Yuliya
Published: January 2020

Computer, electronic and Internet revolutions led to the situation when homogeneous printed text is being replaced by screen audiovisual text comprising verbal and non-verbal units of meaning. This article studies such kind of heterogeneous, polycode-multimodal texts, film texts in particular. The aim of the article is to elicit the correlation of verbal and non-verbal (visual) components of the heterogeneous screen texts. To achieve the aim the analysis of verbal component of the moving continuum in comparison with kinemorphs is being done. The results of the research show that verbal and non-verbal, i.e. visual, units of meaning relate to each other by interdependence and determination. Apart from that, it is found out, that there are associations that lie in the basis of the structural-semiotic organization of the heterogeneous screen texts: association on analogy, juncture and co-occurrence. The analysis shows that contamination of verbal and visual units of meaning leads to the manipulation of the conscience, to the stereotype channeling in particular. The next step of the research is stated – to verify the obtained results on the heterogeneous screen texts videotexts of the Internet.
Ethical Problems of Young-Adult Genre and Book Video Bloging, As Formation of a Reading Circle in Modern Youth
Authors: Boyarshinova E.
Published: January 2020

This paper examines the history and current state of literature for teenagers. In modern criticism young-adult genre stands out in literature for adolescents. An introductory excursion into the history of the concept of “young adults” and literature for this category of readers is given. Criticism of such works is considered by video bloggers who place their clips on Youtube platform. It is analyzed whether these responses affect the book market conditions. According to the most conservative estimates, more than half of the literature published by major publishers is Young-adult books. They are read not only by teenagers, but also by adults who want to immerse themselves in their youth. The theme of Young-adult literature is serious and multifaceted. It attracted both professional authors, whose works become real literary events, and young, non-professional authors. The study of these works is important from the point of view of studying the sociology of teenage life, to understand what young people live, what problems are reflected in such works, albeit in a crooked mirror.

Contemporary Russian Art-Mediadiscourse: Communicative Status
Authors: Tsvetova N.
Published: January 2020

The article analyzes the mediatexts that form the part of the modern Russian art media discourse, which traditionally correlated with cultural and educational journalism. The purpose of the analysis is to describe the key manifestations of the modernization of the communicative orientation of discourse — its communicative status. Using mainly analytical techniques developed by intentional stylistics, the author finds the blurring of segment boundaries within the discourse, which, first of all, manifests itself in the disappearance of the always existing watershed between cultural and educational, art journalism, art PR and advertising art text; changing the semantic structure of texts that format the “elite” segment of art media discourse associated with classical, high art-theater, music, the art of the word; dominance in today’s art media discourse of image-based business projects deployed in time, which are implemented using modern PR techniques. It is obvious that technologically the process of modernization of discourse is carried out under the influence of actualization of national, historical PR experience and assimilation, appropriation, adaptation of the experience of the world, first of all, еuropean. These observations lead to the conclusion that today in Russia the journalistic coverage of classical art is no longer dictated by informative or evaluative, but by incentive intentionality, which indicates the inclusion of the analyzed publications in the system of strategic communication and largely determines the speech form of different genres of media texts of this discursive affiliation.
A PALAVRA COMO CAMPO DE FORÇAS
Authors: Kfouri Ana Maria Barcellos
Published: January 2020

O presente artigo, sobre atuação cênica contemporânea, propõe que se pense a palavra e o corpo sempre em tensão e relação. Discorre sobre a importância de buscar novas práticas pedagógicas e artísticas, em que palavra e corpo são trabalhados fora de uma conduta psicológica, antes conectados a um campo intensivo no qual prevalecem a intensidade em vez da intenção, o acaso no lugar de encadeamentos causais e evolutivos, o ritmo, a oralidade, a sonoridade e os significantes em vez de um fechamento de sentidos. Na primeira parte do texto, os interlocutores nesta investigação, que envolve questões poéticas e políticas, são, principalmente, Gilles Deleuze e Valère Novarina. Na segunda parte, a encenação da peça Uma frase para minha mãe (2018/2019), de Christian Prigent, oferece o estudo de caso para aprofundar as questões levantadas.

O presente texto é um convite para pensar possíveis percepções e enunciações sobre o corpo no campo da educação. Para tanto, nos aproximamos os escritos de Michel Foucault (1989), Gilles Deleuze e Félix Guattari (1995), Giorgio Agamben (2014 - 2017) e Baruch de Espinosa (1998) para construir um pensamento que nos permita atentar para uma vivência da corporeidade no contexto escolar, além das fronteiras da escola tradicionalmente estabelecida. A partir da potência política da costura, damos ênfase à Pedagogia crítico-performativa e às oficinas desenvolvidas pelo NAT, para alargar o leque de possibilidades de agenciamentos sobre o corpo no espaço educacional. Propomos, ao fim, problematizações que se apresentam por olhares outros em defesa de um corpo-potência, atentando para suas dimensões poéticas e performativas.

Authors: Gomes da Silva Daniele
Published: January 2020

O presente trabalho descreve processos de criação cinematográfica no espaço escolar, levados a efeito a partir de um Projeto de Extensão, e registra as experiências de deslocamentos cognitivos e físicos, haja vista que esses processos começam na mente, para se externarem por meio de movimentação, interação e ocupação dos corpos pelos espaços. Deste modo, abre-se possibilidade de (re)inventar a si mesmo e a escola, pois experimenta-se sinestesicamente o cinema. Para sustentar tais colocações, dialogamos com a Pedagogia da Criação (BERGALA, 2008) e as considerações sobre cinema e educação propostas por Fresquet (2013). A metodologia de ação adotada para desenvolvimento da investigação foi a cartografia (KASTRUP, 2008).
CORPO E DANÇA: ANGEL VIANNA E A MANUTENÇÃO DA SENSIBILIDADE
Authors: Feijó Márcia
Published: January 2020

A pedagogia corporal criada e desenvolvida pela Mestra Angel Vianna é o centro desta reflexão sobre sensibilidade na formação do profissional do corpo seja docente, artista ou terapeuta. Sobre a cultura que nos cerca historicamente e sobre a questão da padronização dos corpos, colocamos em debate uma pedagogia corporal não excludente como é a proposta de Angel Vianna. Por entender o corpo humano como o elemento que evidencia nossa presença única no mundo, possuidor de expressão e linguagem individualizada, essa proposta pedagógica procura por meio de práticas educativas de sensibilização, uma forma de colaborar com a capacidade humana particular de se desenvolver e se comunicar, estabelecendo essa prerrogativa na construção de autonomia e expressão própria através do desenvolvimento da atenção ao corpo com criatividade e consciência. Angel Vianna em sua metodologia, estabelece naturalmente uma conduta de aceitação de todos, valorizando a diversidade humana, as diferenças e as limitações individuais garantindo os princípios básicos de ética e respeito mútuos sem espaço para julgamentos ou padronizações. A conscientização do movimento, a dança e a expressão do corpo como potência transgressora, ousada, artística e política, torna-se foco na formação docente da escola Angel Vianna.

Using Fraser’s model of ‘progressive neoliberalism’ to analyse deinstitutionalisation and community care
Authors: Cummins Ian
Published: January 2020

This article will argue that Nancy Fraser’s (2017, 2019) notion of ‘progressive neoliberalism’ provides a conceptual lens that can be effective in the development of a critical analysis of mental health policy in England and Wales during the period of deinstitutionalisation and community care. Mental health policies that came steeped in an originally progressive discourse of choice, empowerment and wider service user rights were introduced by governments largely committed to the free market. In the UK and US, this produced a contradictory position where moves towards a community-oriented vision of mental health service provision were overseen by administrations that were committed to a small state and fiscal conservatism. There were similar developments in other areas. Fraser (2017, 2019) terms this mixture of socially progressive rhetoric and market economics ‘progressive neoliberalism’. Fraser’s model of progressive neoliberalism argues that neoliberalism has colonised progressive discourses. The article outlines this theoretical model and then applies it to the development of community care. It argues that policy responses to the perceived failings of community care focused on increased powers of surveillance, including the introduction of legislation that allows for compulsory treatment in the community. This focus on legislation was at the expense of social investment. The article concludes that the introduction of austerity in the UK has strengthened these trends. For example, The Coalition government (2010–15) introduced new mental health policies such as ‘No decision about me without me’, which emphasised inclusive approaches to service organisation and delivery. At the same time, it followed social and economic policies that increased inequality, reduced welfare payments and entitlements, and cut services. These are all factors that contribute to higher levels of mental distress across society.
Design and equivalent circuit model extraction of a broadband graphene metasurface absorber based on a hexagonal spider web structure in the terahertz band
Authors: Bordbar Arman , Basiry Raheleh , Yahaghi Alireza
Published: January 2020

In this paper, an ultra-wideband terahertz absorber is designed utilizing a graphene-based metasurface. The absorber is composed of three layers including the graphene metasurface, Topas-cyclic olefin copolymer dielectric substrate, and a gold ground layer. The particle swarm optimization algorithm and interpolate quasi-Newton optimization are utilized to find an optimized structure with the widest bandwidth. Full-wave simulations verify achieving absorbance of more than 90% in an extremely wide frequency band within the range of 1 THz to 3.5 THz (fractional bandwidth = 111%) under illumination of a normal incident wave. The proposed structure is polarization insensitive up to a polarization angle of 75°, while the performance of the absorber (absorbance level and bandwidth) is almost fixed for incident angles

Passive non-line-of-sight imaging using plenoptic information
Authors: Lin Di , Hashemi Connor , Leger James R.
Published: January 2020

We present a methodology for recovering the perspective imagery of a non-line-of-sight scene based on plenoptic observations of indirect photons scattered from a homogeneous surface. Our framework segregates the visual contents observed along the scattering surface into angular and spatial components. Given the reflectance characteristics of the scatterer, we show that the former can be deduced from scattering measurements employing diversity in angle at individual surface points, whereas the latter can be deduced from captured images of the scatterer based on prior knowledge of occlusions within the scene. We then combine the visual contents from both components into a plenoptic modality capable of imaging at higher resolutions than what is allowed by the angular information content and discriminating against extraneous signals in complex scenes that spatial information struggles to discern. We demonstrate the efficacy of this approach by reconstructing the imagery of test scenes from both synthetic and measured data.
Single exposure lensless subpixel phase imaging: optical system design, modelling, and experimental study
Authors: Kocsis Péter , Shevkunov Igor , Katkovnik Vladimir , Egiazarian Karen
Published: January 2020

Design and optimization of lensless phase-retrieval optical system with phase modulation of free-space propagation wavefront is proposed for subpixel imaging to achieve super-resolution reconstruction. Contrary to the traditional super-resolution phase-retrieval, the method in this paper requires a single observation only and uses the advanced Super-Resolution Sparse Phase Amplitude Retrieval (SR-SPAR) iterative technique which contains optimized sparsity based filters and multi-scale filters. The successful object imaging relies on modulation of the object wavefront with a random phase-mask, which generates coded diffracted intensity pattern, allowing us to extract subpixel information. The system’s noise-robustness was investigated and verified. The super-resolution phase-imaging is demonstrated by simulations and physical experiments. The simulations included high quality reconstructions with super-resolution factor of 5, and acceptable at factor up to 9. By physical experiments 3

Characterization of anisotropy of the porous anodic alumina by the Mueller matrix imaging method
Authors: Wang Chuhui , Qin Peiwu , Lv Donghong , Wan Jiachen , Sun Shuqing , Ma Hui
Published: January 2020

Porous anodic alumina (PAA) is a photonic crystal with a hexagonal porous structure. To learn more about the effects brought by pores on the anisotropy of the PAA, we use the orientation sensitive Mueller matrix imaging (MMI) method to study it. We fabricated the PAA samples with uniform pores and two different pore diameters. By the MMI experiments with these samples, we found that the birefringence is the major anisotropy of the PAA and that there are many small areas with different orientations that formed spontaneously in the process of production on the surface of the PAA. By the MMI experiments at different orientations of the sample with two different pore diameters, we found that the pores affect the birefringence of the sample and the effect increases with the increased inclination of the sample. To further analyze the PAA, we present a symmetrical rotation measurement method according to the Mueller matrix of the retarder. With this method, we can calculate the average refractive index (RI) of birefringence and the orientation of the optical axis of uniaxial crystal. The results also show the effect of the pores on the anisotropy of PAA.
Lasing in Si3N4-organic hybrid (SiNOH) waveguides
Authors: Kohler Daria , Allegro Isabel , Wondimu Sentayehu Fetene , Hahn Lothar , Freude Wolfgang , Koos Christian
Published: January 2020

Silicon nitride (Si3N4) waveguides offer low-loss wave propagation over a wide spectral range including visible wavelengths and lend themselves to photonic integrated circuits for bio-photonic applications. The Si3N4 device portfolio, however, is so far limited to passive devices that need to be fed by external light sources. This often requires delicate and costly fiber-chip coupling schemes that are subject to stringent alignment tolerances. In this paper, we present and investigate a class of lasers that combine Si3N4 waveguides with light-emitting organic cladding materials in a hybrid approach. These Si3N4-organic hybrid (SiNOH) lasers are operated by optical pumping from the top with low alignment precision. We theoretically and experimentally investigate different SiNOH laser concepts based on spiral-shaped ring resonators and distributed feedback (DFB) resonators. While our devices are designed for an emission wavelength of approximately 600 nm, the SiNOH laser concept can be transferred to a large range of wavelengths in the visible spectrum. The devices are amenable to cost-efficient mass production and have the potential to address a wide range of applications in bio-photonics and point-of-care diagnostics.
RedCap: residual encoder-decoder capsule network for holographic image reconstruction
Authors: Zeng Tianjiao , So Hayden K.-H. , Lam Edmund Y.
Published: January 2020

A capsule network, as an advanced technique in deep learning, is designed to overcome information loss in the pooling operation and internal data representation of a convolutional neural network (CNN). It has shown promising results in several applications, such as digit recognition and image segmentation. In this work, we investigate for the first time the use of capsule network in digital holographic reconstruction. The proposed residual encoder-decoder capsule network, which we call RedCap, uses a novel windowed spatial dynamic routing algorithm and residual capsule block, which extends the idea of a residual block. Compared with the CNN-based neural network, RedCap exhibits much better experimental results in digital holographic reconstruction, while having a dramatic 75% reduction in the number of parameters. It indicates that RedCap is more efficient in the way it processes data and requires a much less memory storage for the learned model, which therefore makes it possible to be applied to some challenging situations with limited computational resources, such as portable devices.
Enhanced calibration for freeform surface misalignments in non-null interferometers by convolutional neural network
Authors: Zhang Lei , Li Chen , Zhou Sheng , Li Jingsong , Yu Benli
Published: January 2020

Most tested surface calibration methods in interferometers, such as the direct coefficients removing method, the sensitive matrix (SM) method, and deep neural network (DNN) calibration method, rely on Zernike coefficients. However, due to the inherent rotationally non-symmetric aberrations in a non-null freeform surface interferometer, the interferograms are usually non-circular even if the surface apertures are circular. The Zernike coefficients based methods are inaccurate due to the non-orthogonality of Zernike polynomials in the non-circular area. A convolutional neural network (CNN)-based misalignment calibration method is proposed. Instead of Zernike coefficients, the well-trained CNN treats the interferogram directly to estimate the specific misalignments. Simulations and experiments are carried out to validate the high accuracy.
Lateral silicon photonic grating-to-fiber coupling with angle-polished silica waveguide blocks
Authors: Han Seungjun , Park Jongwoo , Yoo Sanghwa , Yu Kyoungsik
Published: January 2020

We demonstrate a lateral, planar fiber-to-waveguide coupling strategy for photonic integrated circuits with diffraction grating couplers using angle-polished silica waveguide blocks fabricated with well-established planar lightwave circuit technologies. Compared to the conventional lateral coupling scheme with angle-polished fibers, the demonstrated scheme can significantly decrease the diverging distance between the reflective angle-polished facet and the grating couplers, and thereby maintains the overall coupling efficiency and alignment tolerances of the vertical coupling approach. The proposed method shows a small penalty in coupling efficiency (< 0.1 dB), and in-plane (out-of-plane) alignment tolerance for 1 dB excess loss is approximately 5 µm (9 µm).
Design of photonic-crystal surface-emitting lasers with enhanced in-plane optical feedback for high-speed operation
Authors: Inoue T. , Yoshida M. , Zoysa M. D. , Ishizaki K. , Noda S.
Published: January 2020

Photonic-crystal surface-emitting lasers (PCSELs) use the two-dimensional (2D) resonance at the band-edge of a photonic crystal for lasing, and they feature various outstanding functionalities such as high-brightness lasing, arbitrary shaping of beam patterns and on-chip 2D beam steering. In this paper, to investigate the applicability of PCSELs for high-speed operation, we design PCSELs with enhanced in-plane optical feedback, which enable single-mode lasing inside a circular region the diameter of which is less than 10 µm. To realize a strong in-plane confinement of the lasing mode, we increase the one-dimensional coupling coefficients between counter-propagating waves through the careful design of the lattice points. We also introduce an in-plane heterostructure composed of two photonic crystals with different photonic bandgaps and utilize reflection at the boundary of the two photonic crystals in addition to the optical feedback at the band-edge of each photonic crystal. By using three-dimensional finite-difference time-domain method (3D-FDTD), we confirm that the proposed hetero-PCSELs can achieve single-mode lasing operation inside a 9-µm-diameter and possibly realize a 3-dB modulation bandwidth larger than 40 GHz.
Chirality breakdown in the presence of multiple exceptional points and specific mode excitation
Authors: Gandhi Harsh K. , Laha Arnab , Dey Sibnath , Ghosh Somnath
Published: January 2020

The dynamical parametric encirclement around a second-order exceptional point (EP) enables the time-asymmetric nonadiabatic evolution of light, which follows the chirality of the underlying system. Such light dynamics in the presence of multiple EPs and the corresponding chiral aspect is yet to be explored. In this Letter, we report a gain–loss assisted four-mode-supported optical waveguide that hosts a parameter space to dynamically encircle multiple EPs. In the presence of multiple EPs, we establish a unique nonadiabatic behavior of light, where beyond the chiral aspect of the system, light is switched to a particular mode, irrespective of the choice of the input mode. Proposed scheme certainly opens a step-forward approach in light manipulation to facilitate next-generation integrated photonic systems.
High-energy self-mode-locked Cr:forsterite laser near the soliton blowup threshold
Authors: Ivanov Anatoly A. , Martynov Grigoriy N. , Lanin Aleksandr A. , Fedotov Andrei B. , Zheltikov Aleksei M.
Published: January 2020

At the level of peak powers needed for a Kerr-lens mode-locked operation of solid-state soliton short-pulse lasers, a periodic perturbation induced by spatially localized pulse amplification in a laser cavity can induce soliton instability with respect to resonant dispersive-wave radiation, eventually leading to soliton blowup and pulse splitting of the laser output. Here, we present an experimental study of a high-peak-power self-mode-locking Cr:forsterite laser, showing that, despite its complex, explosion-like buildup dynamics, this soliton blowup can be captured and quantitatively characterized via an accurate cavity-dispersion- and gain-resolved analysis of the laser output. We demonstrate that, with a suitable cavity design and finely tailored balance of gain, dispersion, and nonlinearity, such a laser can be operated in a subcritical mode, right beneath the soliton blowup threshold, providing an efficient source of sub-100-fs 15–20 MHz repetition-rate pulses with energies as high as 33 nJ.
Active modulation of intracavity laser intensity with the Pound–Drever–Hall locking for photoacoustic spectroscopy

Published: January 2020

Here we report a novel, to the best of our knowledge, method of active intracavity intensity modulation for cavity-enhanced photoacoustic spectroscopy (PAS) without the need for any external optical modulators. Based on the Pound–Drever–Hall (PDH) locking technique, a dither is added to the PDH error signal to periodically vary the locking point between the laser frequency and optical cavity within a sub-MHz frequency range. While significantly enhancing the intracavity laser intensity, the optical cavity also acts as an intensity modulator. As a proof-of-principle, we demonstrated the PAS of

Sertoli Cell Alterations in Peripubertal Varicocelized Rats: Evidence of Primary Damage on Spermatogenesis
Authors: Vaz André da Costa , Paccola Camila Cicconi , Mendes Talita Biude , Cabral Regina Elizabeth Lourenço , Simas Joana Noguères , Vendramini Vanessa , Miraglia Sandra Maria
Published: January 2020

Idiopathic varicocele is closely associated with male infertility or subfertility. Sertoli cell is a very important regulator of spermatogenesis. We investigated the morphofunctional alterations in the Sertoli cell and its possible involvement in the establishment of testicular primary lesion in experimental left-sided varicocele, induced from peripuberty. Twenty-five male peripubertal rats (44 days postpartum [dpp]) were distributed into two groups: control (C) and varicocele (V). Experimental left varicocele was induced in rats through the partial ligature of the left renal vein. Euthanasia was performed at 100 dpp. Testicular histopathology and testosterone plasmatic level were evaluated. Transferrin and vimentin proteins were, respectively, used as immunomarkers of Sertoli cell function and structure. Significant reductions in vimentin and transferrin expressions were noticed in androgen-dependent stages (VII and VIII) of the seminiferous epithelium cycle in V rats; testosterone plasmatic level was also reduced. Bilateral testicular histopathological alterations were found in V rats, mainly massive germ cell desquamation. The histological damage and changes in protein expressions occurred bilaterally. The relevant impairment of the functional and structural characteristics of the Sertoli cell, together with the typical massive germ cell desquamation, indicates that Sertoli cell changes can primarily contribute to the significant testicular dysfunction associated with varicocele.
Endomorphins: structure, localization, immunoregulatory activity
Authors: Gein Sergey V. , Baeva Tatyana A.
Published: January 2020

Endomorphins endogenous tetrapeptides with the highest affinity for the -opioid receptor. Currently, two tetrapeptides that differ in one amino acid residue have been isolated and characterized. The structure of endomorphins differs from the structure of members of three main families of opioid peptides: endorphins, enkephalins, and dynorphins, which contain the same N-terminal sequence. In the central nervous system, endomorphins are distributed everywhere, where they are primarily responsible for antinociception. Distribution of endomorphins in the immune system, similar to that of other opioid peptides, has allowed to suggest their active participation in the processes of immune regulation. This review summarizes modern views on the structure of endomorphins, their localization, possible intracellular mechanisms of signal transmission and their effects on the processes of activation, proliferation and differentiation of cells of innate and adaptive immunity. Endomorphins actively modulate the functions of the cells of the immune system. Peptides predominantly suppress adaptive immunity reactions. There effects on the functions of innate immunity cells (granulocytes, macrophages, monocytes, dendritic cells) depending on the conditions and can have either an inhibitory or stimulating orientation. Thus, endomorphins can be promising compounds that can effectively regulate both nociceptive signals and processes in the immune system.

O trabalho envolveu a construção de um índice de disclosure voluntário (IDV) com base em orientações da Organização das Nações Unidas (ONU) e da United Nations Conference on Trade and Development (UNCTAD) direcionadas ao mercado brasileiro. O IDV envolveu oito aspectos, tais como estimativas contábeis críticas; conflitos de interesse no conselho de administração; e, disponibilização de relatório anual, enquanto o nível de internacionalização das firmas foi mensurado de três formas (emissões de ADRs, receitas com exportações e participação  estrangeira no capital social). O método de análise envolveu regressão com dados em painel visando identificar o impacto da internacionalização sobre o  IDV, sendo que tal modelo foi investigado em três momentos distintos: usando toda a amostra e também para duas sub-amostras, uma de empresas internacionalizadas e outra de empresas não internacionalizadas. Como principais resultados, considerando a amostra geral, observou-se que empresas com maior nível de internacionalização apresentam maior nível de disclosure voluntário. Para a sub-amostra de empresas internacionalizadas, encontrou-se uma relação positiva e significativa entre emissão de ADRs, exportações e participação de estrangeiros no capital social com o índice de disclosure construído no trabalho. A partir deste estudo, infere-se que as organizações, sejam nacionais ou multinacionais, deveriam usar as estratégias e mecanismos de disclosure para estruturar e delinear adequadamente seu sistema de informações antes de buscarem consolidar suas estratégias de internacionalização.
THE INFLUENCE OF POISON PILLS ON EXECUTIVE COMPENSATION
Authors: Azevedo Yuri Gomes Paiva , Nakao Sílvio Hiroshi
Published: January 2020

We examine whether the poison pills influence on the executive compensation of Brazilian publicly-traded firms, considering that there is a particularity of this anti-takeover device in Brazilian firms when compared to US firms, since the managers can include in the company's bylaws an "eternity" clause that prevents poison pills change or removal, which may lead to a managerial entrenchment, maintaining managers privileges in the detriment of minority shareholders, including increases in the executive compensation levels. To test our hypotheses, we use a sample of 217 Brazilian publicly-traded firms listed on B3 with available data on Bloomberg® database and Brazilian Securities Exchange Commission website between 2010 and 2017. We use the total, fixed and variable compensations as proxies for executive compensation. However, to mitigate several outliers of these variables, we use the quantile regression as a robust alternative to the extreme sensitivity of the ordinary least squares estimator to modest amounts of outliers. Our main results show that poison pills have a positive influence on total, fixed and variable executive compensation. Furthermore, in an exploratory way, our results show that these "eternity" poison pills also have a positive influence on these proxies of executive compensation. These findings are consistent with the entrenchment hypothesis that since managers are protected in their positions, they may obtain private benefits at the expense of shareholders, such as higher levels of executive compensation. In this sense, our study contributes to the literature by showing that although reducing the risk of a hostile takeover, the poison pills are incurring in an additional agency cost for shareholders that not always leads to the reduction of conflicts between managers and shareholders since these anti-takeover defenses seem not being adopted in the Brazilian context to benefit the shareholders, but to protect managers in their positions.

This research explores students’ skillset development with the introduction of a gamified discipline in an Accounting undergraduate program. We conducted a survey with 118 accounting students enrolled on the last semester from a large public University in Brazil. Using a quantitative approach, the research results indicate that students consider that many skills have been developed during the gamified discipline, such as: curiosity, leadership, initiative, persistence, adaptability, collaboration and critical thinking. The familiarity with tools used in the online game context and the perception of usability of the software used for this gamification experience were positively and significant correlated with the perception of the development of these skills. Despite these positive finds, some students did not like the excess of competition in the course and the random process of the software. These findings contribute to the academic literature and to educators who are interested in introducing gamified strategies in the classroom.

A certificação ISO 14001 compreende um conjunto de normas ambientais, vista como uma das soluções para alcançar a responsabilidade ambiental, aumentando a competitividade das Companhias no mercado nacional e internacional. Assim, esta pesquisa tem por objetivo verificar a relação da implantação do sistema de gestão ambiental (SGA) - ISO 14001 com o endividamento das empresas brasileiras listadas na B3. Para mensurar esse efeito foi utilizada a análise de regressão em painel com estimação dif-in-dif e o teste de média para duas populações. A fonte dos dados utilizada foram demonstrações financeiras das empresas listadas na B3, disponibilizadas pela Economática e informações sobre as certificações disponíveis nos sites das empresas referente ao período de 1996 a 2016. A amostra inicial foi de 8.400 observações em 400 empresas, posteriormente reduzidas para 2.400. Os resultados encontrados apontam evidências de que a certificação ISO 14001 afeta o endividamento de longo prazo de forma positiva e o de curto prazo de forma negativa, ou seja, as empresas com certificação ISO 14001 estão substituindo financiamento de curto por financiamento de longo prazo. Este pode ser resultado de um aumento de confiança devido ao compliance trazido pela certificação ISO 14001.
