Published: August 2020

As experiências de modernização da agricultura no Brasil têm servido como suporte para o governo moçambicano propor mudanças substanciais no seu modelo agrícola e na estrutura de seu espaço agrário. Do mesmo modo que ocorreu no Brasil, Moçambique se torna um território disputado para servir à expansão da fronteira agrícola mundial. No caso específico de Moçambique, o discurso de eliminar a fome, dinamizar a economia, aumentar o PIB – Produto Interno Bruto, são corolários da empreitada geopolítica de grandes corporações internacionais dos EUA – Estados Unidos da América, Japão, China e Brasil para os fins modernizantes. Os trabalhos desenvolvidos por pesquisadores e estudantes brasileiros e moçambicanos, face a essa condição, estão sendo edificadas com base nas seguintes interrogações: por que o processo de criação de melhores condições de vida necessita de métodos violentos que corrói o regime coletiva de propriedade da terra? Até que ponto a “intenção modernizante” pode ser assumida e justificada como verdadeira? Trabalhos de campos, levantamento de fontes, organização de oficinas em Machambas moçambicanas, organização de simpósios no Brasil e Moçambique alimentam as pesquisas e conduzem às reflexões da relação entre geopolítica e modernização da agricultura em Moçambique.

Published: August 2020

O suco de uva é um produto amplamente consumido por suas características nutricionais e presença de compostos fenólicos, os quais possuem importante atividade antioxidante. Dessa maneira, o objetivo deste estudo foi avaliar a atividade antioxidante e o teor de compostos fenólicos totais de diferentes tipos de sucos de uva e néctares, encontrados no comércio de duas cidades do Rio Grande do Sul. Foram selecionados 17 sucos de uva tintos, 06 sucos brancos e 4 néctares, representando a totalidade das amostras encontradas em mercados das duas cidades. A atividade antioxidante foi determinada pela capacidade de varredura do radical livre DPPH● (2,2-difenil-1-picrilhidrazil) e o teor de compostos fenólicos totais (TPT) foi avaliado pelo método de Folin-Ciocalteau. A atividade antioxidante variou de 50,14 a 97,38% e o TPT variou de 143,83 a 1.113,83 mgEAG/mL, considerando sucos e néctares. A maior atividade antioxidante foi encontrada nos sucos tintos, seguidos dos sucos brancos e néctares. Os maiores valores de TPT foram encontrados nos sucos tintos, seguidos dos néctares e sucos brancos. Este estudo colabora com o conhecimento do teor de TPT e atividade antioxidante de sucos produzidos na região Nordeste do estado do Rio Grande do Sul.
MÃOS À OBRA: A REPRESENTAÇÃO DO TRABALHADOR MEXICANO NOS ESTADOS UNIDOS EM SALT OF THE EARTH E ESPALDAS MOJADAS
Authors: Bragança Maurício De 
Published: August 2020

O trabalhador mexicano nos Estados Unidos é um personagem presente tanto nos filmes mexicanos quanto nos estadunidenses ao longo do século XX. Sua inserção na narrativa acompanhou os contextos históricos da relação entre os dois países, sobretudo no que diz respeito ao período das políticas de migração empreendidas entre 1942 e 1964 (Programa Braceros). Tais narrativas cinematográficas apresentavam questões referentes não apenas à mobilização dos trabalhadores mexicanos nos Estados Unidos, mas também no estatuto identitário destas personagens nas narrativas. Neste artigo pretendemos desenvolver uma análise comparada entre dois filmes: o estadunidense Salt of the Earth, dirigido por Herbert J. Biberman em 1954, e o mexicano Espaldas mojadas, dirigido por Alejandro Galindo em 1955.
Is the Gothic Arch a reliable radiographic landmark for migration percentage in children with cerebral palsy?
Authors: Wek Caesar , Chowdhury Piyal , Smith Christian , Kokkinakis Michail 
Published: August 2020

Introduction Reimers migration percentage (MP) is the gold standard for measuring hip displacement in children with cerebral palsy (CP). Hip surveillance registries proposed using the top of the Gothic arch (GA) as a modification in patients with acetabular dysplasia because the classical method (CM) described by Reimers may underestimate hip migration. The aim of this study is to assess the inter- and intra-observer reliability of the modified method (MM) versus the CM and identify their effect on the MP. Methods We performed a retrospective review of 50 children with CP, who had a hip radiograph at our institution between 1st April 2014 and 28th February 2018. All hip radiographs were carefully selected to show the presence of a GA. Four observers measured the MP using the CM and MM for each patient. Interclass coefficient was used to estimate inter- and intra-observer reliability. Results Inter-observer reliability was excellent for the CM with ICC 0.96 (95% CI 0.94 to 0.97) and good for the MM, ICC 0.78 (95% CI 0.51 to 0.89) p < 0.001. Intra-observer reliability was excellent for both methods raging from ICC 0.94 to 0.99 for the CM and ICC 0.89 to 0.95 for the MM. The mean MP was 19% for the CM and 28% for the MM (p < 0.001). Conclusion The CM is more reliable than the MM to measure hip migration in children with CP. If the CM is used and acetabular dysplasia with a GA are present on the hip radiograph, then a 9% hip migration underestimation should be considered on decisions for both referral and surgical management.

Published: August 2020

Pembaharuan hukum pidana adalah sesuatu yang harus dilakukan sebagai bentuk penyesuaian hukum yang berlaku dengan perubahan nilai, zaman, teknologi, wawasan nasional, dan internasional. Pidana mati di Indonesia juga perlu diperbarui menyesuaikan perkembangan tersebut terkhusus pada penyesuaian nilai yang dianut oleh bangsa Indonesia. Penelitian ini bertujuan untuk mengetahui kebijakan formulasi pidana mati dalam perundang-undangan pidana Indonesia di masa sekarang, dan menganalisis kebijakan formulasi hukum yang dicita-citakan tentang pidana mati bersyarat di Indonesia. Penelitian ini menggunakan metode kualitatif dengan pendekatan normatif. Penelitian ini menghasilkan fakta bahwa hukum di Indonesia sekarang belum mengatur tenang pidana mati bersyarat, sehingga masih ada pertentangan antara golongan yang ingin menghapus pidana mati dan golongan yang ingin tetap menerapkan pidana mati. Pidana mati bersyarat diperlukan sebagai jalan tengah antara dua golongan tersebut. Pidana mati bersyarat juga diperlukan sebagai proses evaluatif narapidana dalam menjalani hukuman dan penghormatan terhadap hak asasi manusia sesuai dengan wawasan nasional dan internasional.

Entry Costs, Task Variety, and Skill Flexibility: A Simple Theory of (Top) Income Skewness
Authors: Atolia Manoj , Kurokawa Yoshinori 
Published: August 2020

Abstract
This paper develops a simple model that provides a unified explanation for both an increase in below-top skewness and a much larger increase in within-top skewness of wage income distribution. It relies on a single mechanism based on the fixed costs of firm entry. A decrease in entry costs increases the variety of goods/tasks and thus the demand for higher-skilled workers who are more flexible in handling a variety of tasks, which increases both types of skewness. Differences in flexibility are modeled as differences in the fixed labor setup costs required to handle a given number of tasks. Our numerical experiments in a calibrated model show that a decrease in entry costs – entry deregulation – can be a quantitatively important source of both the increase in below-top skewness and the much larger increase in within-top skewness observed in the U.S. Moreover, the experiments imply that the observed differences in entry deregulation can cause significant differences in the top skewness across countries that have similar technological change. This can provide an answer to Piketty and Saez’s (2006) question: Why have top wages surged in English speaking countries in recent decades but not in continental Europe or Japan, which have gone through similar technological change?
Cardiotoxic effects and myocardial injury: the search for a more precise definition of drug cardiotoxicity
Authors: Cardinale Daniela Maria , Zaninotto Martina , Cipolla Carlo Maria , Passino Claudio , Plebani Mario , Clerico Aldo 
Published: August 2020

Abstract
Drug-induced cardiotoxicity is a major clinical problem; cardiotoxic drugs may induce both cardiac dysfunction and myocardial injury. Several recent studies reported that cardiac troponins measured with high-sensitivity methods (hs-cTn) can enable the early detection of myocardial injury related to chemotherapy or abuse of drugs that are potentially cardiotoxic. Several authors have some concerns about the standard definition of cardiotoxicity, in particular, regarding the early evaluation of chemotherapy cardiotoxicity in cancer patients. Several recent studies using the hs-cTn assay indicate that myocardial injury may precede by some months or years the diagnosis of heart failure (HF) based on the evaluation of left ventricular ejection fraction (LVEF). Accordingly, hs-cTn assay should considered to be a reliable laboratory test for the early detection of asymptomatic or subclinical cardiotoxic damage in patients undergoing cancer chemotherapy. In accordance with the Fourth Universal Definition of Myocardial Infarction and also taking into account the recent experimental and clinical evidences, the definition of drug-cardiotoxicity should be updated considering the early evaluation of myocardial injury by means of hs-cTn assay. It is conceivable that the combined use of hs-cTn assay and cardiac imaging techniques for the evaluation of cardiotoxicity will significantly increase both diagnostic sensitivity and specificity, and also better prevent chemotherapy-related left ventricular (LV) dysfunction and other adverse cardiac events. However, large randomized clinical trials are needed to evaluate the cost/benefit ratio of standardized protocols for the early detection of cardiotoxicity using hs-cTn assay in patients receiving chemotherapy for malignant diseases.
Effects of Media Exposure on Regional Associations
Authors: Peng Chun-Yi 
Published: August 2020

AbstractAlthough there is a long-standing tradition discounting the effect of media exposure on language variation, this study shows how televised media formulate and reinforce the sociosemiotic links between linguistic features and their regional associations. The Mandarin aspect markeryouis an interesting case in this regard, as it is semiotically linked mostly, if not exclusively, to Taiwanese Mandarin by many Chinese mainlanders, even though the feature is, in fact, also observed in many southern Mandarin varieties on the mainland. Drawing upon Agha’s concept of enregisterment, the goals of this study are 1) to provide empirical evidence of the semiotic work that media do to language, and 2) to test whether exposure to Taiwanese televised media contributes to the mismatch between the regional association and actual geographical distribution of the aspect markeryou. The findings of this study suggest two levels of media influence: meta-awareness and indexicality. The relationships between these two levels are incremental and mutually constitutive, and televised media play the role of catalyzing these reciprocal processes.
Reasoning and Appraisal in Multimodal Argumentation
Authors: Wu Ting 
Published: August 2020

AbstractThe development of new media enlarges the repertoire of semantic resources in creating a discourse. Apart from language, visual and sound symbols can all become semantic sources, and a synergy of different modality and symbols can be used to complete argumentative reasoning and evaluation. In the framework of multimodal argumentation and appraisal theory, this study conducted quantitative and multimodal discourse analysis on a new media discourseBuilding a community of shared future for humankindand found that visual symbols can independently fulfill both reasoning and evaluation in the argumentative discourse. An interplay of multiple modalities constructs a multi-layered semantic source, with verbal subtitles as a frame and a sound system designed to reinforce the theme and mood. In addition, visual modality is implicit in constructing the stance and evaluation of the discourse, with the verbal mode playing the role of “anchoring,” i.e. providing explicit explanation. A synergy of visual, acoustic, and verbal modalities could effectively transmit conceptual, interpersonal, and discursive meanings, but the persuasive result with the audience from different cultural backgrounds might be mixed.
Director Network, Governance of Independent Directors and Efficiency of Enterprise Capital Allocation
Authors: Chen Shan , Nie Yingzhi 
Published: August 2020

Abstract
Based on the social network analysis theory and employing multivariate linear regression, this study empirically examines the effect of network location of independent directors in China’s listed companies on the efficiency of capital allocation of the enterprises, using a research sample of China’s A-share companies listed in Shanghai and Shenzhen Stock Exchanges over the period of 2013–2016. The research shows that the higher the network centrality of independent directors, the more it can improve the inefficient investment of enterprises and enhance the efficiency of capital allocation. Specifically, as the investment inefficiency is divided into under-investment and over-investment, the findings show that the more central the independent directors are in the director network, the better, which not only can suppress the over-investment of enterprises, but also can effectively alleviate the under-investment of enterprises. Based on the further study of nature of the enterprises’ property rights, in comparison with that of state-owned enterprises, the network centrality of independent directors of private-owned enterprises plays a more significant role in improving the efficiency of corporate investment.
Structure of end moraines and dynamics of the recession phase of the Warta Stadial ice sheet, Kłodawa Upland, Central Poland
Authors: Drążczyk Magdalena Anna 
Published: August 2020

Abstract
The occurrence of end moraines reflects the dynamics of an ice sheet, and their inner structure is determined by processes taking place in marginal zones. In the southern part of the Kłodawa Upland of Central Poland, such moraines were formed, but opinions conflict as to their origin, including the influence of local transgression of the ice sheet, as well as its areal and frontal recession. The primary aim of this article is to analyse the inner structure of forms to define the dynamic state of the Warta Stadial ice sheet of the Odra Glaciation (Saalian). The conducted research includes fieldwork at four key sites, where lithofacial analysis was performed, as well as a geomorphological and geological mapping that included two cross-sections in greater detail. In exposures, the work focused on deformed structures of sediments. Description of key sites was extended by the creation and the analysis of general geological cross-sections. Considering the results of the research, the Kutno end moraines should not be classified as push moraines – they were revealed to be accumulative in character.

AbstractIn this study, we reported an easy, rapid, cost-effective and environmentally benign method for the fabrication of silver nanoparticles (Ag-NPs) usingOlea ferrugineaas reducing, capping and stabilizing agent. For this, an aqueous extract of leaf and bark ofO. ferrugineawas treated with 1 mM AgNO3, which reduces Ag ions to Ag-NPs by establishing reddish brown color. The synthesized Ag-NPs were spherical crystals, with a mean size of 23 and 17 nm for leaf- and bark-mediated Ag-NPs, respectively. Fourier transform infrared spectroscopy affirmed the role of leaf and bark extracts ofO. ferrugineaas reducing, capping and stabilizing agent. These biosynthesized Ag-NPs showed profound antibacterial activity against Gram-negative (Pseudomonas aeruginosaandEscherichia coli) and Gram-positive (Streptococcus pneumoniaandStaphylococcus aureus) bacteria. The highest antibacterial activity was shown by bark Ag-NPs againstS. aureus(14.00 mm), while leaf Ag-NPs showed higher activity againstS. pneumonia(13.00 mm). Additionally, they produced effective antioxidant activity against 2,2-diphenyl-1-picrylhydrazyl (DPPH) as compared to plant extracts and positive control. It was observed that the bark-mediated Ag-NPs had higher percentage (90%) of scavenging potential than the leaf-mediated Ag-NPs (78%). The significance of the current study is the synthesis of eco-friendly, easy and cost-effective Ag-NPs as biomedical products.
All laughter is nervous: An anxiety-based understanding of incongruous humor
Authors: Granitsas Dean Anthony 
Published: August 2020

AbstractMirth may alleviate negative feelings that could be aroused by a humor stimulus. Pity and embarrassment have been advanced as anxieties that could be caused by cruel and obscene humor in the absence of mirth. Incongruity, however, remains an explanatory challenge for arousal/anxiety-based interpretations of humor. In order to find ways that incongruity could be provocative, this paper analyzes similarities between the external stimuli of mirthful responses and the external stimuli of paranoid responses, which both demonstrate ambiguity and uncanniness. It is posited that mirth deactivates a fearful reaction to incongruity, suppressing suspicion and delusions that could be triggered when a surreal event is interpreted in a non-playful way. While extreme incongruity may arouse discomfort in any perceiver, it is argued that paranoid individuals have a higher sensitivity, due in some cases to early, traumatic exposure to an incongruous stimulus that resisted mirthful deactivation. These observations are presented without theoretical commitment, but with emphasis on the explicatory potential of the play and false alarm theories.

Published: August 2020

AbstractSupercritical water oxidation may be used as waste treatment technique that consists of oxidizing organic and inorganic matter using water at supercritical conditions. It was developed as an alternative technique in order to limit the risks of secondary pollution. The purpose of this study is the development of simulation tools in stationary state in supercritical water oxidation (SCWO) tubular reactor which has been numerically investigated basing on using a two-dimensional modeling approach applying the k-ε turbulence model, and on the international association for the properties of water and steam formulation (IAPWS-IF97). A Multiphysics simulation using Comsol Multiphysics 5.2 software for the supercritical water oxidation of “cutting oil Biocut 35” as a pollutant is reported. First, the heat transfer coefficient was estimated and the obtained temperature and species concentration profiles were compared to experimental data where a quite good agreement was obtained as confirmed by the acceptable coefficient of determination value. Finally, once the used model was validated, numerical simulations were performed to describe the behavior of the reactor investigating the effects of operating conditions such as temperature, pollutant feed concentration and reactor inlet flow rate, on dependent variables like outlet temperature, chemical oxygen demand removal (COD) and the highest temperature reached inside the reactor. This last parameter was considered in the study to take into account the operation safety. The significance of the studied factors and their interactions were quantified and analyzed by means of the full factorial design of experiment (DOE). The results showed that the effect of initial temperature was the most important for the three responses, followed by the feed concentration then to a lesser extent the flow rate. The effect of initial temperature was positive for outlet temperature, maximal temperature and cutting oil removal. The interaction temperature-feed concentration was the only significant one for the COD removal and the maximal temperature. The results defined an operation safety zone of the SCWO reactor based on the superposition of the three studied dependent variables and imposed constraints on the inside reactor temperature and the pollutant outlet concentration.
