Authors: War Javeed Ahmad , Srivastava Santosh Kumar
Published: June 2020

A new series of imidazole linked thiazolidinone hybrid molecules was designed and subsequently synthesized through a feasible, three step reaction protocol. The structures of these molecules were established using FT-IR, 1H NMR, 13C NMR and HRMS techniques. In vitro susceptibility tests against some Gram positive (Staphylococcus aureus and Bacillus subtilis) and Gram negative bacteria (Escherichia coli and Pseudomonas aeruginosa) exhibited broad spectrum potency of the molecules. The most potent molecule (S2A7) amongst the screened molecules, showed minimum inhibitory concentration (MIC) value not less than 2.0 µg/mL which was at par with the reference drug Streptomycin. Structure activity relationships revealed nitro and chloro groups being crucial for bioactivity when present at meta position of arylidene ring in 3-(3-(imidazol-1-yl)propyl)-5-(benzylidene)-2-(phenylimino)thiazolidin-4-one. Deoxyribonucleic acid (DNA)and bovine serum albumin (BSA) binding studies for S2A7 under simulated physiological pH were probed using UV-Visible, fluorescence quenching, gel electrophoresis and molecular docking techniques. These studies established that S2A7 has strong binding affinity towards DNA and binds at the minor groove of DNA with binding constant (Kb) of 0.1287×102 L/mol. Molecular docking simulations of S2A7 with DNA and BSA predicted binding affinity of -9.2 and -7.2 kcal/mol, respectively. Van der Waals forces and hydrogen bonding interactions were predicted as the main forces of interaction. With DNA, S2A7 exhibited specific binding affinity towards adenine-thiamine base pairs. The compound S2A7 forms a stable complex with BSA by binding at subdomain IIIA implying high bio-distribution of the compound.

Published: June 2020

The title compound 5-methyl-1,3-bis(3-nitrobenzyl)pyrimidine-2,4(1H,3H)-dione was obtained by reaction of thymine with 3-nitrobenzylbromide in the presence of cesium carbonate. Characterization of the product was achieved by NMR spectroscopy and its stability was probed in basic condition using UV-Visible analysis. Furthermore, the molecular structure was confirmed by X-ray diffraction analysis. The compound crystallizes in orthorhombic Pna21 space group with unit cell parameters a = 14.9594 (15) Å, b = 25.711 (3) Å, c = 4.5004 (4) Å, V = 1731.0 (3) Å3 and Z = 4. The crystal packing of the title compound is stabilized by intermolecular hydrogen bond, π···π and C−H···π stacking interactions. The intermolecular interactions were furthermore analyzed through the mapping of different Hirshfeld surfaces. The two-dimensional fingerprint revealed that the most important contributions to these surfaces come from O···H (37.1%), H···H (24%) and H···C/C···H (22.6%) interactions. The interaction energies stabilizing the crystal packing were calculated and were presented graphically as framework energy diagrams. Finally, the energy-framework analysis reveals that π···π and C−H···π interactions energies are mainly dispersive and are the most important forces in the crystal.

Abstract. Global coupled chemistry-climate models underestimate carbon monoxide (CO) in the Northern Hemisphere, exhibiting a pervasive, negative bias against measurements peaking in late winter and early spring. While this bias has been commonly attributed to underestimation of direct anthropogenic and biomass burning emissions, chemical production and loss via OH reaction from emissions of anthropogenic and biogenic VOCs play an important role. Here we investigate the reasons for this underestimation using aircraft measurements taken in May and June 2016 from the Korea United States Air Quality (KORUS‐AQ) experiment in South Korea and the Air chemistry Research In Asia (ARIAs) in the North China Plain (NCP). For reference, multispectral CO retrievals (V8J) from the Measurements of Pollution in the Troposphere (MOPITT) are jointly assimilated with meteorological observations using an Ensemble Adjustment Kalman Filter (EAKF) within the global Community Atmosphere Model with Chemistry (CAM-chem) and the Data Assimilation Research Testbed (DART). With regard to KORUS-AQ data, CO is underestimated by 42 % in the Control-Run and by 12 % with the MOPITT assimilation run. The inversion suggests an underestimation of anthropogenic CO sources in many regions, by up to 80 % for Northern China, with large increments over the Liaoning province and the North China Plains (NCP). Yet, an often-overlooked aspect of these inversions is that correcting the underestimation in anthropogenic CO emissions also improves the comparison with observational O3 datasets, and observationally constrained box model simulations of OH and HO2. Running a CAM-chem simulation with the updated emissions of anthropogenic CO reduces the bias by 29 % for CO, 18 % for ozone, 11 % for HO2 and 27 % for OH. Longer lived anthropogenic VOCs whose model errors are correlated with CO are also improved while short-lived VOCs, including formaldehyde, are difficult to constrain solely by assimilating satellite retrievals of CO. During an anticyclonic episode, better simulation of O3, with an average underestimation of 5.5 ppbv and a reduction in the bias of surface formaldehyde and oxygenated VOCs can be achieved by separately increasing by a factor of two the modeled biogenic emissions for the plant functional types found in Korea. Results also suggest that controlling VOC and CO emissions, in addition to wide spread NOx controls, can improve pollution ozone over East Asia.
Assessing historic water extents in rapidly changing lakes: a hybrid remote sensing classification approach
Authors: Mullen Connor , Muller Marc F.
Published: June 2020

Abstract. The empirical attribution of rapid hydrologic change presents a unique data availability challenge in terms of establishing baseline prior conditions. On the one hand, one cannot go back in time to collect the necessary in situ data if it were not serendipitously collected when the change was taking place. On the other hand, modern satellite monitoring missions are often too recent to capture changes that are ancient enough to provide sufficient observations for adequate statistical inference. In that context, the four decades of continuous global high resolution monitoring enabled by the Landsat missions are an unrivaled source of information to study hydrologic change globally. However, extracting the relevant time series information in a systematic way across Landsat missions remains a monumental challenge. Cloud masking and inconsistent image quality often complicate the automatized interpretation of optical imagery. Focusing on the monitoring of lake water extents, we address this challenge by coupling supervised and unsupervised image classification techniques. Unsupervised classification is first used to detect water on unmasked (cloudless and high quality) pixels. Classification results are then compiled across images to estimate the inundation frequency of each pixel, hinging on the assumption that different pixels will be masked at different times. Inundation frequency is then leveraged to infer the inundation status of masked pixels on individual images through supervised classification. Applied to a representative set of global and rapidly changing lakes, the approach successfully captured water extent fluctuations obtained from in situ gauges (when applicable), or from other Landsat missions during overlapping time periods.

COVID-19 and homes for the aged: care or an announced death?
Authors: Watanabe Helena Akemi Wada , Domingues Marisa Accioly Rodrigues da Costa , Duarte Yeda Aparecida de Oliveira
Published: June 2020

Despite all efforts to contain the COVID-19 pandemic in Brazil, little attention has been paid to homes for the aged, which are the home of thousands of older people and serve as social care facilities. There is no provision in the national regulations for the operation of these long-term care facilities with respect to physical structure, human resources or equipment to offer specific health care services to residents. Thus, homes for the aged are unable to offer proper care to people with COVID-19. These facilities have had difficulty in acquiring and maintaining the stocks of personal protective equipment for residents and staff. This letter is intended to draw attention to this reality and prevent the occurrence of a cruel and inhumane geronticide. Government authorities and the media need to work together and help unveil this reality, which, although present, is hidden and unknown to the majority of the population.
Contradições do Experimento Neoliberal do Porto Maravilha no Rio de Janeiro
Authors: Santos Junior Orlando , Werneck Mariana , Ramos Novaes Patricia
Published: June 2020

O objetivo do artigo é levantar algumas teses ou argumentos sobre as especificidades da neoliberalização da cidade do Rio de Janeiro, tomando o caso da renovação do Porto Maravilha, que também podem contribuir para a compreensão do contexto urbano brasileiro e latino-americano. Os resultados da análise desenvolvida possibilitam interpretar as contradições associadas à implementação do projeto de renovação do Porto Maravilha em torno de três teses. A primeira afirma que a compreensão das transformações urbanas no Porto Maravilha deve levar em consideração as características específicas da configuração urbana da cidade - uma ordem urbana híbrida, desigual e combinada -, e do papel da cultura negra e da diáspora africana na sua configuração. A segunda tese argumenta que o Porto Maravilha se constitui em um experimento neoliberal deflagrado por uma coalizão de interesses, mas que sua implementação é constrangida pela ordem urbana híbrida, desigual e combinada e, ao mesmo tempo, a modifica, num processo de destruição criativa multiescalar que produz uma versão local de um fenômeno global. A terceira tese argumenta que os projetos de renovação urbana no Rio de Janeiro promovem um tipo particular de elitização, a gentrificação periférica, caracterizada por processos de branqueamento e tentativas de aniquilação da cultura negra, mas as resistências sociais resultam na reprodução da ordem urbana híbrida, desigual e combinada. Em termos de métodos e técnicas aplicados, a pesquisa envolveu a combinação de diferentes técnicas de coletas de dados, destacando-se a análise documental e as observações direta e participante.
A produção do espaço urbano na orla de Porto Alegre, Brasil
Authors: Misoczky de Oliveira Clarice
Published: June 2020

O artigo tem como objetivo desvelar o processo de produção do espaço na Orla do Rio Guaíba na cidade de Porto Alegre, capital do Rio Grande do Sul - Brasil. O estudo se posiciona no campo dos Estudos Críticos Urbanos e tem como repertório fundamental o pensamento marxista a partir da obra de Henri Lefebvre. A análise dos dados se dá a partir dos conceitos de totalidade, realidade e alienação em conjunto com a tríade da produção do espaço que proporciona um movimento trialético entre o espaço concebido (dos técnicos, arquitetos e urbanistas), o espaço percebido (a prática espacial), com o espaço vivido (os espaços de dominação e/ou de transformação). O argumento passa pela associação da ação do mercado imobiliário em relação a fundos de investimentos, a imagem da cidade via marketing urbano e do empreendedorismo urbano com a inovação tecnológica e a criação de espaços de consumo de lazer que operam na valorização do valor do espaço urbano construído. Ainda assim, grupos insurgentes por meio de ocupações e movimentos sociais se colocam no processo visando uma produção social do espaço urbano, ante a produção capitalista neoliberal.

Published: June 2020

En este artículo explicamos cómo el big data presenta nuevos desafíos más allá de la protección de la privacidad. En específico, comentamos cómo el big data puede afectar la competencia en los mercados, al facilitar determinadas conductas anticompetitivas. Para introducirnos en el tema, el artículo comienza haciendo mención al concepto y utilidad del big data. Luego, hacemos referencia a la manera en que el big data puede contribuir en la formación de barreras a la entrada o puede ser fuente de abuso de poder de mercado. El artículo continúa profundizando en la importancia de analizar el big data en las operaciones de concentración, especialmente en el caso de las killing acquisitions, tanto en los mercados digitales como en la industria en general. Al tratar las operaciones de concentración, el artículo se refiere a la dicusión sobre la carga de la prueba y los umbrales, en las fusiones preventivas. Finalmente, se aborda la posibilidad de que el big data pueda ser facilitador de colusión, permitiendo conductas tales como el pricing algorithms, por medio de algoritmos que pueden aprender a coludirse.

Authors: Pino Yancovic Mauricio , Coloma Correa Rodrigo
Published: June 2020

Esta investigación aborda el problema de la brecha que se produce entre lo que ofrecen los textos académicos sobre Derecho Probatorio y los aprendizajes que esperan obtener de ellos, tanto jueces como litigantes. Para la detección del estado en que actualmente nos encontramos, se da cuenta de un estudio de casos, mediante el uso de entrevistas semi-estructuradas aplicadas a jueces, litigantes y académicos. Entre los resultados más relevantes destacan: i) distintas perspectivas acerca de lo que es posible lograr con la prueba en los procesos judiciales, especialmente, si las pruebas de un juicio pueden efectivamente determinar aquello que ha ocurrido en el pasado; y ii) tipos de producción académica esperada por jueces y abogados, quienes buscan un enfoque práctico, es decir, presentación de casos judiciales concretos con estrategias para su gestión. Estos resultados conducen a repensar la manera en que los jueces, litigantes y académicos se relacionan; y sobre todo cómo debieran concebirse los procesos de formación de quienes en el futuro llegarán a participar en dichas sub-comunidades.

Published: June 2020

This research studied the role of lockup in assessing price and volume of IPOs during the expiration of lockup in Malaysian market. The reaction of price is measured by the abnormal return while the reaction of volume is measured by the abnormal volume. The companies were selected from the years 2010 to 2018 and only companies that were still listed in Bursa Malaysia were chosen. The time frame of the study was 30 days before and 30 days after the expiration date of lock up provision. The results may show for these circumstances of i) the volume will remain and the price will decrease; ii) volume will be decreased and price will be decreased too and iii) promoters retain percentage of shares during expiration date. For situation number i), it might show the sign of a quite good quality of performance of IPOs in stock market. Evidently, the second circumstance shows decrease in price and volume of IPOs after expiration date. The scenario actually leads by demand and supply of stock. Another important evidence which supports the insignificant result is promoters retain percentage of shares during expiration date. The amounts that should be released by the companies are not offered to the market during that time. By looking at the Signaling Theory, insiders of IPOs firms who are previously restricted from selling their holdings have the first chance to sell large propositions of their shares. Investors will know the dates of IPO lockup expiration and numbers of shares by looking at the prospectus. Due to the scenario, the price and volume of IPOs will be reacting during expiration date based on this theory. It is hoped that this study will help investors or any Malaysian market participation especially in the IPOs market to notice the situation in Malaysian market regarding the lock up provision.

Published: June 2020

Mental health illness becomes one of the major illnesses in Malaysia aside from heart disease. It was recently reported that 29.2% of Malaysians are suffering from mental health illness which increases threefold from the previous year. Majority of the Malaysians suffering from mental health illness comes from the lowest income group. This shows that the lowest income group has less opportunity to seek treatment due to the cost. Even though other countries have started to offer mental health insurance such as the United States of America, United Kingdom, Australia and recently Singapore, Malaysia is still way behind in offering coverage for mental health illness. Therefore, the objective of this paper is to study the mental health takaful from the perspective of Maqasid shariah. The results from this study show that mental health takaful is able to meet the requirement of Maqasid shariah and preserve the benefits of, and prevent harm to human wellbeing. Furthermore, this study will provide an insight to the takaful industry for developing new products that could help mental health disorder patients.
Credit Management in Full-Fledged Islamic Bank and Islamic Banking Window: Towards Achieving Maqasid Al-Shariah
Authors: Muhammad Najihah , Alwi Sharifah Faigah Syed , Muhammad Nabihah
Published: June 2020

The percentage of non-performing loans (NPL) and non-performance financing (NPF) in Malaysia commercial banks is under control and does not increase in its percentage since the year 2014 to 2016. These scenarios are the result of the stringent credit management procedures in the commercial banks which if not properly followed could affect banks’ profitability and liquidity. However, there are critics by the public on how Islamic banks normally tend to punish their customers who are the real traders or businessman without fixed monthly income when they slightly late in paying their periodical payment for the bank’s facility or financing. Islamic bank is supposed to help the customer in order for it to achieve maqasid al-Shariah (objectives of Shariah). Thus, this study intends to compare the credit management’s procedure in one of the full-fledged Islamic banks and one of the conventional banks which also offer Islamic banking window. This study also aims to identify the achievement of maqasid al-Shariah through the procedures of credit management in the two banks. This study adopted the qualitative methodology where semi-structured interviews are conducted with 2 bankers from one of the full-fledged Islamic banks and one of the conventional banks which also offer Islamic banking window. Results from this study indicated that each banks has their own strategies and procedures with regard to credit management. Their credit management plans were structured to help customers to secure their loans, financing and assets as well as protecting them from bankruptcy and insolvency which basically comply with maqasid al-Shariah. From this study, it is recommended for commercial banks to apply a strict approval process for loan and financing as well as a strict credit monitoring system to avoid NPL and NPF.

Authors: Hajduk Nancy Ann , Zhang Mingyuan
Published: June 2020

This study examined the relationship between technology factors students use beyond school and their standardized math assessment scores. Student frequency of seeking math help online, playing digital games involving math, and programming computers outside of school were studied. An analysis of data taken from the National Assessment of Educational Progress (NAEP) dataset was done to compare student responses from survey data to mathematics achievement scores of 8th-grade students. This secondary data analysis was completed using multiple t-tests to compare means and determine significance. Results found in this study showed that beyond school, frequent use (daily or almost) of websites for math homework help, playing digital games involving, and programming computers had negative effects on scores. Once/twice a year or month scored better than never for website use and digital games, while never programming scored higher than all other frequencies. Students may benefit from instructional guidance as to which websites are most beneficial for homework help with math. An effort to help students recognize math use in digital games may increase their awareness and intentional use outside of school. Early classroom instruction on computer programming may help provide a better understanding of its relationship with mathematics.

Using Interactive Picture-Book Read-Alouds with Middle School EFL Students
Authors: Sun Chia-Ho
Published: June 2020

The current study investigated the effects of interactive picture-book read-alouds on middle school EFL students’ word inference ability and attitudes toward reading in English. To this end, two classes of seventh-grade students from a public middle school in Taiwan participated and were randomly divided into two groups: an interactive picture-book read-aloud (IPBRA) group and a control group. The intervention took place in a 40-minute morning study hall per week over a period of 10 weeks. The two groups were tested using Reading Attitude Survey (RAS) and Word Inference Assessment (WIA) two weeks before and then two weeks after the intervention was implemented to assess improvement. Results indicated that interactive picture-book read-alouds had a positive impact on EFL middle schoolers’ reading attitudes and use of text and prior knowledge to infer the meanings of unfamiliar words. This study suggests that the motivating learning atmosphere of interactive picture-book read-alouds provided positive classroom environment and enabled students to have fun while interacting freely with one another, which, in turn, facilitated reading attitude changes, leading to better learning and better performance on word inference in subsequent reading activities.

Published: June 2020

Nitrification is the oxidation process of NH4+ to NO3- microbially. The nitrification process can produce compounds in the form of NO3-, N2O, or NO which can cause environmental pollution through water, soil, or air, thus harming living things. The research was conducted to find ways to inhibit or control nitrification effectively and sustainably. The experiment was carried out in a plastic greenhouse located in Plesungan, Karanganyar until the maximum vegetative planting period of corn around May-June using a completely randomized design three replications. Andisols soil media was taken from Tegalrejo Village, Tengaran District, Semarang Regency 07º25'28.3 '' LS and 110º31 '35.7 '' BT with an altitude of 760 meters above sea level. There are 5 treatments, one control, four are natural inhibitor treatments in the form of litter addition. The litter used was Gliricidia maculate, Albizzia falcataria, Senna siamea, and Tithonia diversifolia. Statistical analysis showed that treatment just significantly affect NO2- concentrations (potential nitrification), not significantly affect NH4+, NO3- concentrations, and efficiency utilization of N. However, measurement results in the laboratory and field showed that the addition of local litter could inhibit nitrification, which was demonstrated through the efficiency of N utilization. Tithonia diversifolia because it has the highest average N utilization efficiency of 25.79%, 58.71% more efficient than control treatments. Also followed by plant growth results showed that the root’s dry weight and canopy’s dry weight positively correlated with NH4+ concentrations and efficient utilization of N, also canopy’s dry weight negatively correlated with NO2- concentrations (potential nitrification). The highest results occurred in the Tithonia diversifolia treatment.

Aim: The aim of this study was to analyze the relationship between dental caries and hormonal, biochemical parameters in pediatric patients with early childhood caries (ECC).

Methodology: This study was conducted on fifty pediatric patients who presented with complaints of pain and caries and underwent dental treatment under general anaesthesia. In this study, the hormonal, biochemical parameters (glucose, urea, uric acid, creatinine, AST, ALT, GGT, CRP, Sodium, Potassium, Calcium, Glucose, Iron, TSH, FT3 and FT4) which were routinely taken from patients before general anaesthesia and the number of decayed, extracted and filled teeth (DMFT) obtained as a result of clinical and radiographic examination were evaluated statistically in patients aged 2-6 years.  Statistical analysis was performed using Independent Samples T-Test and Spearman correlation coefficient at a 0.05% significance level.

Results: According to the data obtained, DMFT average of fifty children (male: 35; female: 15) included in the study was found to be 8.26. The mean DMFT was 7.93 in females and 8.40 in males. No statistical relationship was found between DMFT and gender in statistical analysis. (p>0.05). Uric acid and GGT values, which are among the hormonal and biochemical parameters, were found to be outside the normal range in 61.22% of the patients. However, statistical analysis revealed that there was no significant relationship between DMFT and hormonal, biochemical parameters. (p>0.05).

Conclusions: In this study, it was concluded that dental caries did not cause a significant change in hormonal and biochemical blood parameters in pediatric patients with ECC.

Authors: Gierczyk Błażej , Kujawa Anna
Published: June 2020

The Wielkopolski National Park is located in western Poland, near Poznań City. Its unique postglacial landforms are covered with various (semi)natural and anthropogenic ecosystems. The mycobiota of this Park has been studied for 90 years; however, current state knowledge is still insufficient. In 2018, a few-year- long project on the chorology, richness, and diversity of fungal biota of this area was started. In the first year, 312 taxa of macromycetes were found. Among them, 140 taxa were new for the biota of the Wielkopolski National Park. Five species (Botryobasidium robustius, Hebeloma subtortum, Leccinum brunneogriseolum, Pachyella violaceonigra, and Sistotrema athelioides) were new for Poland, and 26 taxa were new for the Wielkopolska region.

This study was carried out to investigate heavy metals concentrations: lead (Pb), cobalt (Co), cadmium (Cd), zinc (Zn), nickel (Ni), copper (Cu) and manganese (Mn) in Musa paradisiaca (plantain), Zea mays (maize), Cucumeropsis manii (melon), Manihot esculenta (cassava) and soil samples from dumpsites in Onne, Eleme Local Government Area, Rivers State, Nigeria. The plant leaf and soil samples were measured for heavy metals concentrations using atomic absorption spectrophotometer. The health risk index (HRI) of the heavy metals following the consumption of these plant materials by the populace was estimated using standard protocols. The heavy metals concentrations in the leaf samples ranged from 0.012–14.712 mg/kg, whereas those of the soil samples were within the range of 2.543–16.459 mg/kg. Cd concentrations in the soil and leaf samples were above the maximum permissible level according to the World Health Organization (WHO). The bioaccumulation of the heavy metals followed the trend: (M. paradisiaca) Zn > Pb > Co > Mn > Cu > Cd > Ni; (Z. mays) Mn > Pb > Co > Zn > Cu > Cd > Ni; (C. mannii) Mn > Co > Pb > Cu > Zn > Cd > Ni; (M. esculenta) Zn > Pb > Mn > Cu > Co > Ni > Cd. The highest bioaccumulation of the heavy metals occurred in M. esculenta. The estimated HRI of Pb in M. esculenta was greater than 1. HRI > 1 was indicative that the consumer population is not safe. Cassava-based meals from the dumpsites contained Pb at toxic level, whereas Co, Cd, Zn, Ni, Cu, and Mn concentrations in plantain-, maize- and melon-based meals were relatively within safe limits.
„Partizipative Gesetzgebung“ – Möglichkeiten und Grenzen der Legitimationsverstärkung durch Bürgerbeteiligung

Published: June 2020

Several German “Länder” are currently testing participatory methods to obtain opinions and ideas of citizens on legal proposals . They aim at achieving outputs that are widely accepted by the public, and thus considered to be better . These methods, known as participatory legislation, raise high expectations in relation to possible vitalizing effects on parliamentary democracy . However, the term is misleading due to the fact that such consultation processes can neither replace nor complement representative democracy, which is based on the German constitution . At the most, its benefits can be found in strengthening legitimacy . But even political scientists assume limits concerning the input-, throughput-, and output-legitimacy of “participatory legislation” . Legitimacy can only be strengthened if transparent rules for its use and its binding effects are clearly stated and if they include control rights of parliament . Otherwise, there could be a risk of a shift in power from the legislative to the executive power .
Public Provocation to Commit a Terrorist Offence: Balancing between the Liberties and the Security
Authors: Ramešová Kristina
Published: June 2020

Modern terrorism is global and decentralized like cyberspace. While the Darknet is mostly used by terrorists for fundraising campaigns and illicit trading, publicly accessible social platforms such as Twitter, Facebook or YouTube are abused for terrorist propaganda. Combating terrorism remains one of the top priorities of the European union (hereinafter as “the EU”). The approach towards the online content possibly connected to terrorist propaganda has become stricter.This paper focuses on the development of the EU legislation on the offence related to terrorist activities: the public provocation to commit a terrorist offence, as well as on the obligations of hosting service providers. It also analyses the impact of the Directive (EU) 2017/541 of the European Parliament and of the Council of 15 March 2017 on combating terrorism and replacing Council Framework Decision 2002/475/JHA and amending Council Decision 2005/671/JHA. The article observes a changing attitude on private monitoring of online information in the development of the EU legislation. It analyses changes in the Proposal for a Regulation of the European Parliament and of the Council on preventing the dissemination of terrorist content online. These changes signify a shift in the perception of the necessary level of freedom to receive and impart information through the internet.
O CRIME DE VIOLÊNCIA DOMÉSTICA: ATO REITERADO OU NÃO, EIS A QUESTÃO
Authors: Poiares Nuno Caetano Lopes de Barros
Published: June 2020

A violência doméstica é um problema social que ganhou uma visibilidade acrescida no século XXI, através de uma consciencialização da sociedade portuguesa para a importância do combate e da prevenção desse fenômeno. No entanto, persistem dúvidas, junto dos operadores do Direito, maxime os magistrados, advogados e policiais, quanto ao preenchimento dos pressupostos da ação típica desse crime, mormente a necessidade de uma reiteração de condutas. No presente artigo procede-se a uma análise legal e jurisprudencial com o objetivo de se reduzir a subjetividade conceitual e contribuir para uma melhor operacionalização na prática jurídica. Concluímos que a jurisprudência tem caminhado com base em conceitos que potenciam a complexidade da discussão e que não permitem uma clarificação do tema sub judice.
Movimento #EleNão: reconhecimento e afirmação do ato de fala das mulheres na política
Authors: Schwengber Maria Simone Vione , Pinheiro Naira Leticia Giongo Mendes
Published: June 2020

O foco deste artigo está em discutir a emergência de vozes das mulheres brasileiras na contemporaneidade – da condição de silêncio e inferiorização das “subalternas” até as fraturas e, por consequência, as falas e manifestações nas redes digitais e nas ruas. No artigo, propõe-se um debate sobre as seguintes questões: como tem se dado a passagem entre o silêncio e a fala das mulheres nos espaços públicos? A partir de que condições? Como corpus das análises, utilizamos o movimento #EleNão (2018). O percurso teórico-metodológico para a análise é inspirado na perspectiva foucaultiana do acontecimento discursivo. Das análises, destacamos que o movimento #EleNão reatualiza a luta do reconhecimento do outro da política – Elas. #EleNão emerge como política de performatividade, de ações corporais e gestuais de resistência, de exposição do direito de falar, de aparecer no sentido de existir, de lutar contra as precariedades das existências. #EleNão produz sentidos de ação política no imaginário social brasileiro, isto é, reposiciona certa saída da condição das mulheres como subalternas que não falam. #EleNão surge como espaço para tensionar/pensar o feminismo nos interstícios de suas igualdades e diferenças no campo das relações de gênero.
The Conventional Lies: An Almost Forgotten Concept
Authors: Râmbu Nicolae
Published: June 2020

The concept of conventional lie, first defined by Friedrich Nietzsche, should be used in the discourse of the cultural sciences. This is because the series of phenomena that it designates is usually mistakenly classified either in the category of stereotypes or in the one of prejudices. In this article, the thesis that conventional lies represent a specific element of culture as a ‘software of the mind’ is supported.
Solar System as it really is and Curating as/in Common/s
Authors: Tyzlik Carver Magda
Published: June 2020

In this proposition of curating in/as common/s I am interested in a particular relation between curating and commons. I claim that there is a link between curating and ‘commoning’, that is the activity and process that produces the commons, and that this link is based in practice. It lays in the fact that the two employ forms of organisation, a particular kind of arrangement of social and aesthetic relations, space, time, forms of behaviour, customs, and ways in which these are governed and controlled, in other words the way in which they are held in common. When we say that something is curated the understanding is that we are dealing with a collection assembled and displayed accord- ing to a curatorial vision and under curator’s direction. Regardless if we are dealing with an übercurator with total control over exhibition, or if the curator’s role is instrumental in delivering the museum’s mission, or if indeed collaborative forms of curating or co-curating are engaged in process of curatorial production, a curator can be considered an apparatus of power, a dispositif in a Foucauldian sense. A different form of organisation is in- voked, however, when we refer to commons which are understood as a self-organised community shaping, managing and utilising resources through ‘community control’.
Thinking with the Animal-Hacker
Authors: Pritchard Helen
Published: June 2020

In the depths of the Cumbria hills a dairy cow changes its route to stare deep into the camera lens of the ‘Environmental Virtual Observatory’ (EVO) (www.evo-uk.org). Downstream at 15 minute intervals organic matter is pushed through turbidity probes, sometimes causing the computation to glitch and upload its own movement into a data storage warehouse. In this muddy, messy situation of the EVO there is something lurking, something which might be described as the ‘Animal-Hacker’ the non-human animal, an entity that exploits the computational ecology, reconfigures it in an act of what Donna Haraway would describe as “worlding”.
Back to the Future in a Place Called America
Authors: Vanegas Gabriel , Zielinski Siegfried
Published: June 2020

Our media and current technologies are the result of a global form established by Western thought. This thought, as in many parts of the world was imposed particularly in The New Spain in the discovery by Christoph Columbus in the late 16th century. Before the European contact, pre-America had a different way of thinking to the West and therefore a different development and understanding of concepts such as media, technology, time, body and space. On one hand the official history shows a pre-Columbian poor picture in technological developments, but on the other hand archaeological discoveries demonstrate an illuminated past with a more sustainable and different form of “hight technology.” To get closer to this form, we have to consider the worldview of pre-Columbian cultures as the central matrix for their technological developments. The aim of this research is to extend the pre-Columbian understanding so that we could approach archaeological discoveries and access to alternative forms of knowledge to expand Western boundaries.
Identificación del alumnado de Educación Primaria con las narrativas históricas locales y nacionales. Estudio de caso en un contexto multicultural
Authors: Cardoso Guillamón Nerea , Molina Puche Sebastián , Ortuño Molina Jorge
Published: June 2020

En el presente trabajo se analiza la relación existente entre la enseñanza de la historia y la formación de identidades colectivas en una sociedad como la actual, caracterizada por la pluralidad cultural. Para ello, se ha realizado una investigación de carácter principalmente cualitativo en la que, mediante el empleo de cuatro instrumentos de recogida de información y de la triangulación de datos, se ha podido comprobar la necesidad de reformulación de los contenidos históricos por la falta de representación de la diversidad cultural en la escuela. A pesar de esto, los resultados nos han mostrado que el empleo de metodologías alternativas que fomenten la investigación, el trabajo cooperativo y el pensamiento crítico puede resultar una herramienta muy útil para superar las narrativas históricas presentes en el currículo de Educación Primaria.
Modeling of Energy Savings Performed by a Barbecue Oven Isolated with Terracotta Bricks

Published: June 2020

This work is devoted to a numerical study of the energy savings achieved by an oven insulated with terracotta bricks compared to an uninsulated oven. The numerical methodology is based on the nodal method and the transfer equations were obtained by making an energy balance on each node. The equations were then discretized using an implicit scheme with finite differences and solved by the Gauss algorithm. Numerical results validated by the experiment show that the insulation of the oven with terracotta bricks considerably reduces the energy losses through the walls, but the reduction level varies according to the thickness of the bricks. The optimal thicknesses of the bricks are between 3 and 4 cm, which corresponds to energy savings of between 60 to 70% compared to the uninsulated oven. The energy saved increases the energy efficiency of the oven from 15-17% to 25-29%.
Novas geotecnologias aplicadas ao estudo geomorfológico: exemplo de morfometria da Voçoroca do Areal, Cacequi-RS
Authors: Krein Rademann Lucas , Trentin Romario
Published: June 2020

Nas últimas décadas o desenvolvimento de novas tecnologias tem proporcionado um grande avanço da ciência. Nas geotecnologias um dos maiores avanços foi o desenvolvimento de Veículos Aéreos Não Tripulados (VANTs) que permitem a obtenção de dados de alta qualidade, tendo um grande potencial para o uso na geomorfologia. Neste trabalho, foram utilizados dados obtidos com aerolevantamento realizado com VANT para a análise morfométrica da Voçoroca do Areal em Cacequi-RS. Para tanto, foi realizado um voo com um VANT multirotor, Phantom 4 a uma altura de voo de 150m, posteriormente os dados foram processados através do algoritmo Structure from Motion. Em seguida, foram classificadas áreas de avanço da voçoroca e calculados diversos parâmetros morfométricos. A voçoroca possui dinâmicas distintas em diferentes porções, tendo mais a montante áreas de avanço mais alargadas e longas com profundidades menores, na porção central um grande desenvolvimento vertical com grande volume erodido e na porção mais a jusante áreas de avanço com menor intensidade. Por fim, os dados obtidos permitiram a análise da morfometria da Voçoroca do Areal, fornecendo dados com extrema qualidade e acurácia. A utilização destas novas geotecnologias ainda tem muito a contribuir com a análise geomorfológica, principalmente nos mapeamentos em nível de detalhe.

Abstract

NEW GEOTECHNOLOGIES APPLIED TO THE GEOMORPHOLOGICAL STUDY: EXAMPLE OF MORPHOMETRY OF THE AREAL GULLY, CACEQUI-RS

In the last decades the development of new technologies has brought about a great advance in science. In geotechnologies, one of the biggest advances was the development of Unmanned Aerial Vehicles that allow obtaining high quality data, with great potential for use in geomorphology. In this work, data obtained with aerial survey with UAV were used for the morphometric analysis of Voçoroca do Areal in Cacequi - RS. For this purpose, a flight was performed with a multirotor UAV, Phantom 4 at a flight height of 150m, afterwards the data were processed using the Structure from Motion algorithm. Afterwards, gully advance areas were classified and several morphometric parameters were calculated. The gully has different dynamics in different portions, having in the area upstream more extended and long areas of progress with smaller depths, in the central portion a large vertical development with a large eroded volume and in the downstream areas, with less intense advancement areas. Finally, the data obtained allowed the analysis of Voçoroca do Areal morphometry, providing data with extreme quality and accuracy. The use of these new geotechnologies still has a lot to contribute to the geomorphological analysis, mainly in the detailed mappings.
