Comparative Performance of Fungicides, Biofungicides, Host-plant Defense Inducers, and Fertilizer in Management of Phytophthora Root Rot on Boxwood
Authors: Neupane Sandhya , Baysal-Gurel Fulya
Published: June 2022

Phytophthora root rot, caused by Phytophthora nicotianae Breda de Haan, is one of the destructive diseases of boxwood (Buxus sempervirens L.) and can affect all growth stages of field- and container-grown boxwood plants. Management is a problem and is only possible through an integrated approach. In this study, the efficacy of fungicides, biofungicides, host-plant defense inducers, and fertilizer were evaluated to manage Phytophthora root rot of boxwood. The objective of this experiment was to develop fungicide and biofungicide recommendations for Phytophthora root rot management in boxwood production. Field and greenhouse experiments were conducted in 2019 (Trial 1) and 2020 (Trial 2). The field experiment was arranged in a completely randomized design with four plots per treatment with five single ‘Green Velvet’ boxwood plants per plot. The greenhouse experiment was arranged in a completely randomized design with five single ‘Green Velvet’ container-grown boxwood plants per treatment. Plots/containers were inoculated with P. nicotianae grown on rice grains. Plant growth data such as height and average width were recorded at the beginning and end of the experiments. Total plant fresh weight and root fresh weight were recorded at the end of the experiments. Roots were assessed for root rot disease severity using a scale of 0% to 100% roots affected. Treatments used in both experiments were fungicides—ametoctradin + dimethomorph, fluzapyroxad, mefenoxam, oxathiapiprolin, pyraclostrobin, pyraclostrobin + boscalid; host-plant defense inducers—aluminum tris-drench, aluminum tris-foliar, potassium salts of phosphoric acid; biofungicides—Trichoderma harzianum Rifai strain T-22 + Trichoderma virens strain G-41, Bacillus amyloliquefaciens Priest; fertilizer—water-soluble nitrogen (nitrogen 5%) and soluble potash; and combination of water-soluble nitrogen, soluble potash, and T. harzianum Rifai strain T-22 + T. virens strain G-41. All treatments were drench applied except one of the aluminum tris, which was applied as foliar. The controls were nontreated, inoculated and nontreated, and noninoculated boxwood plants. In the greenhouse experiments, treatments that effectively reduced disease severity were pyraclostrobin, ametoctradin + dimethomorph, and oxathiapiprolin. In the field experiments, treatments such as pyraclostrobin, oxathiapiprolin, mefenoxam, fluzapyroxad, and combination of water-soluble nitrogen (nitrogen 5%), soluble potash, and T. harzianum Rifai strain T-22 + T. virens strain G-41 effectively reduced Phytophthora root rot severity. Oxathiapiprolin and pyraclostrobin are the chemical fungicides that were effective in both field and greenhouse experiments.
Effect of Light-emitting Diodes, Ultraviolet-B, and Fluorescent Supplemental Greenhouse Lights on Strawberry Plant Growth and Response to Infection by the Anthracnose Pathogen Colletotrichum gloeosporioides
Authors: Smith Barbara J. , Rezazadeh Amir , Stafne Eric T. , Sakhanokho Hamidou F.
Published: June 2022

Supplemental lighting is frequently used to extend daylength for strawberries (Fragaria ×ananassa) grown in greenhouses and high tunnels; however, information is limited on the effect of these lights on disease development. We evaluated the effect of ambient light and six supplemental light treatments [red, blue, and white light-emitting diodes (LEDs), separately; a combination of red, blue, and white LEDs; wide-spectrum fluorescent (WSF); and WFS + ultraviolet B (UV-B)] on plant growth and disease response of strawberries grown in a greenhouse. Plants were exposed to supplemental light treatments for 17 h each day. In the WSF+UV-B treatment, plants were exposed to WSF light during the day and to UV-B light for 3 hours during the night. Two trials were conducted; each trial contained five or six cultivars and was replicated three times. Twice during each trial, detached leaves from each cultivar in each light treatment were inoculated with a conidial suspension of the anthracnose crown rot pathogen, Colletotrichum gloeosporioides and rated for disease severity 10 days later. There was a significant difference due to light treatment and to cultivar in relative chlorophyll content and plant growth parameters. Plant injury ratings were lowest in the white LED, WSF, and WSF+UV-B treatments. Plants in the combination LED and red LED light treatments received higher injury, lower vigor scores, and lower relative chlorophyll content values than plants in all other light treatments. After inoculation of detached strawberry leaves with C. gloeosporioides in Trial 1, there was a significant effect due to light treatments on disease severity ratings (DSRs) after 18 weeks’ exposure to light treatments with the DSRs in the WSF+UV-B treatment being lower than those in all other treatments except those in the red LED treatment. There was not a significant effect in DSRs due to light treatments after 24 weeks in Trial 1 or after 4 or 22 weeks in Trial 2. There were significant effects due to cultivar on DSRs in both trials: ‘Strawberry Festival’, ‘Pelican’, and ‘Seascape’ received the lowest DSRs. This study showed an effect of supplemental light on several strawberry plant growth parameters, including a harmful effect of high-intensity red LED irradiation.
Conflitos de agência, Governança Corporativa e o serviço público brasileiro: um ensaio teórico
Authors: Abilio Martins Vinicius , Jeremias Junior Jair , Fernando Enciso Luis
Published: June 2022

RESUMO

O serviço público brasileiro é fundamentado em leis e regras que tendem o serviço, em alguns casos, ser exercício de forma em que o interesse de quem o executa seja divergente de quem o contratou. A teoria da agência afirma que a possibilidade de se contratar e delegar poderes a administradores que não necessariamente possuam alguma participação no capital societário da empresa, acarreta um problema de partição entre propriedade e controle, em que os interesses do proprietário, no caso, chamado de principal, acabam não se tornando os mesmos dos gestores contratados, no caso, o agente. O papel da Governança Corporativa é acompanhar o relacionamento entre a administração (agentes) e os proprietários (principais) e reduzir as diferenças existentes entre eles, principalmente em relação a assimetria de informações. Este trabalho, através de um ensaio teórico, busca apresenta as relações existentes, fundamentada na literatura, a respeito da Teoria da Agência e da Governança Corporativa na aplicação no setor e serviços públicos. No contexto apresentado, uma boa estrutura de Governança torna-se recomendável para uma eficaz administração e gestão nos órgãos do setor público. Foi possível perceber que os princípios da Governança Corporativa, sendo Transparência (disclosure), Prestação de Contas (accountability) e Equidade (fairness) vão de encontro aos princípios da Administração Pública, principalmente relacionados a Publicidade e Moralidade.

Influência da governança corporativa para o recebimento de subvenções e assistências governamentais em Companhias abertas
Authors: Scheren Gilvane , Dalchiavon Ariberto , Dias de Moura Geovanne
Published: June 2022

RESUMO

O estudo objetivou verificar a influência da governança corporativa para o recebimento de subvenções e assistências governamentais em companhias abertas listadas na B3 S.A. Para tal, realizou-se pesquisa descritiva, documental e quantitativa, com dados de 2010 a 2016. Para identificação das subvenções e assistências governamentais foram verificadas as contas de “Reserva de Incentivos Fiscais” do P.L. Como proxy para governança corporativa, utilizou-se o Índice de Ações com Governança Corporativa Diferenciada (IGC). Os resultados demonstraram que os setores de utilidade pública, consumo cíclico e consumo não cíclico se destacaram positivamente, vez que estes setores possuíam o maior número de empresas que receberam algum tipo de subvenção e assistência governamental no período investigado. Os resultados revelaram também que a governança corporativa influencia para o recebimento de subvenções e assistências governamentais. Concluiu-se que no Brasil, país que possui um ambiente institucional frágil, caracterizado por um mercado acionário menos ativo e com proteção legal aos direitos de propriedade significativamente inferiores ao de países como Estados Unidos, por exemplo, as práticas de governança corporativa são vistas como mecanismos que contribuem para o cumprimento das obrigações relacionadas às subvenções e que auxiliam para um melhor uso dos benefícios recebidos. Por isso, influenciam positivamente para o recebimento de subvenções e assistências governamentais.

Governança no setor público: avaliação do nível de aderência de uma instituição de ensino superior ao modelo de governança pública da IFAC
Authors: Rodrigues Sobreira Karoline , Salgueiro Rodrigues Junior Manuel
Published: June 2022

RESUMO

Diversos países estão no caminho para uma mudança das características do setor público, através de uma remodelação político-administrativa que seja projetada para assegurar maior responsabilidade e melhor prestação de serviços. As Instituições de Ensino Superior (IES) públicas também estão inseridas nesse contexto, sendo sua demanda constante e o volume de recursos disponível cada vez mais restrito, acarretando a necessidade do aperfeiçoamento contínuo do seu modelo de gestão (Sales et al, 2015). O presente estudo tem o objetivo de fazer uma avaliação na gestão de uma Universidade Pública do Ceará, com base no referencial teórico "International Framework: Good Governance in the Public Sector" produzido pela International Federation of Accountants (IFAC) e Chartered Institute of Public Finance and Accountancy (CIPFA), verificando a aderência da gestão quanto a esse modelo internacional. Trata-se de um estudo de caso, realizado através de um questionário para pessoas do corpo de governo da IES, com base no citado Framework do IFAC adaptado para a escala Likert. Os resultados revelam que existe a percepção de um nível Alto de adesão aos princípios de boa governança elencados pelo IFAC/CIPFA, com um percentual de 80,34%. Os princípios de “integridade, ética e compliance” e “acessibilidade e envolvimento dos stakeholders” foram destaques positivos, pois obtiveram os melhores níveis, com 92,38% e 87,62%, respectivamente. No entanto, mesmo com os resultados elevados, existem princípios passíveis de melhoria. Destaca-se a “Gestão de Riscos e Desempenho” e “Desenvolvimento Sustentável”, que obtiveram os menores percentuais (71,43% e 72,86%, respectivamente).

Governança coorporativa: um fator chave para o aumento do nível de competitividade
Authors: Dos Santos Henrique , Campos Mendes Jullye
Published: June 2022

RESUMO

As práticas de governança corporativa proporcionam aos proprietários de empresas a capacidade de gerir de forma estratégica e monitorar as ações da direção executiva. A teoria econômica tradicional trata que a governança coorporativa surge da necessidade da separação entre a propriedade e a gestão empresarial. Este artigo busca analisar qual o impacto das práticas de governança coorporativa no nível de competitividade das empresas que compõem o IBRX50 (Índice Brasil 50 – carteira composta pelas cinquenta ações mais negociadas na Bolsa). Devido ao contexto atual, é de grande importância estudar o tema para explicitar a relevância das melhores práticas de governança coorporativa não apenas como trata a teoria, mas como uma ferramenta de melhoria nos resultados das organizações. A relação nível de competitividade e nível de governança corporativa das 50 empresas de capital aberto inclusas no IBrX50, segundo dados do ano de 2015, foi descrita utilizando o indicador financeiro Return On Assets (ROA) e a classificação da empresa de acordo com os níveis de governança corporativa da B3.Nos resultados apurados, as empresas listadas no Novo Mercado possuíam um ROA médio duas vezes maior que as empresa listadas no Nível 1 e 2 e quase nove vezes maior que as empresas listadas somente no nível básico. As empresas listadas no Novo Mercado também apresentaram o maior valor de ROA da amostra e as menores variações negativas verificadas. Desta forma, concluímos que, no período avaliado, as empresas da IBrX50 que apresentaram os melhores níveis de governança corporativa, apresentaram também os maiores níveis do indicado financeiro ROA e como consequência maiores níveis de competitividade.

Authors: De Fátima Teston Sayonara , Salete Filippim Eliane
Published: June 2022

RESUMO

 

O objetivo geral da pesquisa foi investigar o processo de sucessão em empresas familiares à luz do modelo tridimensional de Gersick, Davis, Hampton e Lansberg (1997), o qual considera que há inter-relação entre família, empresa e propriedade em empresas desta natureza. Para contextualizar a arena das empresas familiares, estabeleceram-se critérios de ordem objetiva e conveniência, pois foi preceito a facilidade de acesso às informações familiares e organizacionais. Adotou-se predominantemente a perspectiva da pesquisa qualitativa de caráter descritivo, com método multi casos. A primeira frente de pesquisa foi a revisão bibliográfica, seguida pelas entrevistas, pesquisa documental e registro da observação em duas empresas do setor de serviços de Chapecó, Santa Catarina, Brasil. A interpretação dos resultados se deu cotejando os achados da realidade pesquisada com a literatura de base. Concluiu-se que o modelo tridimensional pode contribuir para preparar o sucessor para trilhar ações e tomar decisões, contudo este modelo não pode ser considerado como ação isolada para a realização da sucessão na empresa familiar.

Purpose of the study: This study aims to analyze the relationship between product innovation and strategic resources used by the furniture enterprises, under the perspective of sustainable competitive advantage, with the intention to identify the resources previous to innovation.
Methodology/approach: The method used in this research is a quantitative and descriptive study, through a survey, applied to 1067 companies in Brazilian furniture industry. The data analysis occurred through Structural Equation Modeling.
Originality/Relevance: Product innovation and strategic resources are capable of providing great potential for economic transformation. It is strategically acknowledged that there is a relationship between product innovation and the use of resources, however, there are as yet insufficient empirical studies to determine which resources influence product innovation. Another important aspect is to evaluate the influence of Environmental, Social and Governance sustainability precepts in the development of new products.
Key findings: In the empirical study, noticed that Product Innovation results from the use of resources, which configures innovation antecedents.
Theoretical/methodological contributions: This study contributes the advancement of science, which can be used to analyze the antecedents of Product Innovation, which pointed out that companies with strategic resources can expand the capacity of innovation by generating sustainable Product Innovation, which leads to the success of a new product.
Social contributions/to management: This study can contribute to managerial decisions, as the results indicate that the Success in New Product Development proved to be an essential form of competitive advantage, comparing the results of Product Innovation with competitors and relating this performance to the use of Environmental, Social and Governance principles.
Fractons, dipole symmetries and curved spacetime
Authors: Bidussi Leo , Hartong Jelle , Have Emil , Musaeus Jørgen , Prohazka Stefan
Published: June 2022

We study complex scalar theories with dipole symmetry and
uncover a no-go theorem that governs the structure of such theories
and which, in particular, reveals that a Gaussian theory with
linearly realised dipole symmetry must be Carrollian. The gauging of
the dipole symmetry via the Noether procedure gives rise to a scalar
gauge field and a spatial symmetric tensor gauge field. We construct
a worldline theory of mobile objects that couple gauge invariantly
to these gauge fields. We systematically develop the canonical
theory of a dynamical symmetric tensor gauge field and arrive at
scalar charge gauge theories in both Hamiltonian and Lagrangian
formalism. We compute the dispersion relation of the modes of this
gauge theory, and we point out an analogy with partially massless
gravitons. It is then shown that these fractonic theories couple to
Aristotelian geometry, which is a non-Lorentzian geometry
characterised by the absence of boost symmetries. We generalise
previous results by coupling fracton theories to curved space and
time. We demonstrate that complex scalar theories with dipole
symmetry can be coupled to general Aristotelian geometries as long
as the symmetric tensor gauge field remains a background field. The
coupling of the scalar charge gauge theory requires a Lagrange
multiplier that restricts the Aristotelian geometries.
Empirical assessment of the impact of external reserves on economic growth in Nigeria
Authors: Ibrahim Adama Joseph , Ohwofasa Bright , Onabote Ademola
Published: June 2022

In the last few decades, the continuous depreciation in the value of the naira occasioned by the dwindling external reserves affected the exchange rate resulting in several macroeconomic fundamentals in Nigeria. The objective of the study is to examine the impact of external reserves on economic growth in Nigeria. The study utilizes the descriptive approach for the trend analysis, while the autoregressive distributed lag (ARDL) model was relied upon in scrutinizing the contemporaneous dynamics for the unrestricted ECM. The data that were culled from several issues of the Central Bank of Nigeria’s annual report and statement of account covered the period 1986–2020. Descriptively, the study finds that economic growth rate and external reserves witnessed fluctuations with the latter being relatively more pronounced. Accordingly, the study finds that in the long run, all the explanatory variables were key determinants of economic growth in Nigeria. Specifically, economic growth is significantly and positively responsive to changes in external reserves by 0.22%, inflation rate by 0.08%, and a one period lag of GDP of 0.21% contrary to its negative response to changes in exchange rate of 0.10% in the short run. The paper recommended that the government may consider providing conducive environment for increased productivity, thereby increasing foreign reserves. Likewise, the situation that may encourage exchange rate misalignment should be avoided. Finally, inflation rate must be controlled within a single digit.

Self-organization of remote employees in Lithuanian companies
Authors: Staniulienė Sonata , Leonavičiūtė Austėja
Published: June 2022

The paper deals with employees’ self-organization as a modern form of organizing a company’s activities in a remote work environment, which was eventual and challenging in the pandemic, but, undoubtedly, is being further developed in companies due to perceived benefits. The aim of the paper is to analyze the self-organization of remote employees. For research methodology, in a quantitative approach, a survey of 196 working remotely employees in various Lithuanian companies by size, industry or sector was conducted using a questionnaire to analyze their self-organization activities and capabilities at the individual, group and organizational level. The survey data were statistically processed and analyzed, indicating percentages, means, medians, standard deviations, and correlations. It was found that for the vast majority of employees (79-91% in different components), self-organization is most developed at the level of individual work while working remotely. This allows employees to achieve a work-life balance and greater job satisfaction. However, the involvement of remote employees via self-organizing of group activities and decision-making as well as solution of problems important to the company in a competitive environment, is not sufficiently developed. In practice, this means that self-organization of their individual work can be delegated to employees, but more efforts are needed to involve remote employees in management processes.

Marketing Research of Supply and Demand in the Regional Energy Market
Authors: Alinazarova M. A.
Published: June 2022

The study is devoted to the energy market of the Sughd region of the Republic of Tajikistan. The features of marketing in the energy sector are highlighted and the authors’ interpretations of the definition of “marketing” in the energy sector are given. The functions of marketing activities in the development of the energy sector of the region are considered. Examples of the correlation between supply and demand for energy products, including electricity, are given for further forecasting the consumption of these products. The ratio analysis of supply and demand of electricity in a certain area was carried out. To identify factors affecting the demand of electricity consumers, an analysis was carried out using statistical and mathematical calculation methods. As a result, a factor that has a greater influence on the demand of electricity consumers has been identified. The ways of solving marketing research for the further successful functioning of the energy company in the interests of society and the social well-being of the population are proposed.

Purpose of the study. The purpose of this paper is to study the state of the regional energy market on the basis of marketing research that characterizes the activities of an energy company; identification of indicators such as consumer dissatisfaction with energy products. The paper is based on a dynamic analysis of analytical and statistical information about ongoing processes in the energy sector. The task is to conduct marketing research of supply and demand in the regional energy market.

Materials and methods. The information base of the study is analytical information and statistical data on indexes of supply and demand for energy products, including electricity. The methodological basis of the study is represented by statistical methods of information analysis: comparative analysis and analysis of time series.

Results. Based on the results of an economic and statistical analysis of consumer demand indicators for the use of energy products, including electricity, factors influencing demand have been identified. Of the three selected factors, it is especially worth noting the demand of consumers using electricity, which are population density indexes, weather conditions and the number of rainfall days in a particular region, it is theoretically established that population density is a more influential index.

Conclusion. Energy is the main branch of the national economy of the country, which contributes to the development of the economy and the normal life of the population. Until now, the problem of providing the population and the national economy of the regions of the republic with energy goods and electricity makes us think about new ways to solve the problem. Since hydroelectric power generation in the country is the share of hydroelectric power plants, given the economic and social condition of the country in the power supply system, it will be appropriate to create a marketing system platform.
Statistical Analysis of the Patterns of Global Investment Development in China
Authors: Loseva A. V.
Published: June 2022

The purpose of the study is to assess the possible impact of patterns and trends in the development of foreign investment activity of China on the prospects of Russian-Chinese economic cooperation in this area, including in terms of support for the Russian energy sector. The relevance of the study is due to the growing influence of the People’s Republic of China in solving global economic and political issues, as well as the importance of its role as a strategic partner of the Russian Federation, which makes it necessary to assess future prospects.

The research methods are methods of analyzing time series, including identifying trends, as well as assessing the structure and structural shifts to obtain an overall picture of the structural transformations of foreign direct investment of China in regional and sectoral sections.

The results of the study. Chinese foreign direct investment in the last two decades has been characterized by an intensive growth in volumes, resistant to global economic crises; analysis of their geographical structure demonstrates the constancy of such a feature as maximizing the opportunities of global offshore zones and countries granting privileges to foreign investors; the sectoral structure of Chinese foreign direct investment has certain patterns of change that are consistent with the goals and objectives of economic development of China set by five-year plans, which makes it possible to predict and find solutions in the field of Russian-Chinese cooperation; a trend has been identified to increase the attention of Chinese investors to the issue of capital formation in the Russian economy. In addition, an assessment of the analytical capabilities provided to users by the official statistics of China in terms of information about investment processes is given.

Conclusion. Statistical analysis of the indicators of foreign investment activity of China over a long period of time allows us to evaluate and characterize its strategic behavior as one of the world’s largest investors, focused primarily on solving the problems of developing its own economy and its global expansion in the long term. The significance of such studies will now increase, given the importance of the development of foreign economic relations with China for the Russian Federation based on the increased potential of interaction between the two countries in recent years.
Overcome of Cisplatin Resistance in Ovarian Cancer by Combination of
Low-intensity Ultrasound and Cisplatin
Authors: Kip Bilgi , Aydin Omer
Published: June 2022

Backgorund:

Platinum-based chemotherapeutics are the main treatment options for
ovarium cancer. However, the development of drug resistance is one of the major issues in chemotherapy.
Even targeting a specific pathway may not produce an efficient sensitization to the
chemo agent due to various pathways related to developing resistance against cisplatin. Hence,
more effective strategies against drug resistance are essential for cancer treatment. In the presence
of the ultrasonic waves, increased membrane porosity enables more drug uptake into the cancer
cell. Therefore, the promising method in cancer therapy is seen as the use of the combined effect
of chemotherapy and low-Intensity Ultrasound (LIUS) to overcome chemoresistance.

Objective:

The present study aimed to examine the effects of Ultrasound (US)+Cisplatin (Cis)-
based combination therapy to advance an effective treatment against drug resistance in cisplatinresistant
ovarian cancer cells A2780 (A2780cis) under in vitro conditions.

Methods:

Treatment groups as Cis and LIUS with two different ultrasound parameters (10% duty
cycle (DC), 1 MHz, 1.0 W/cm2, 1 min and 50% DC, 1 MHz, 1.0 W/cm2, 3 min) were investigated
to cope with the chemoresistance in A2780cis. After Cis therapy with IC50 concentrations determined
in A2780 and A2780cis, drug-sensitive/resistant ovarian cancer cells were treated by ultrasound.
The effects of the US+Cis combination therapy were evaluated by cell viability assays,
colony formation, and cell cycle analyses.

Results:

In both US parameters, the waveform was shown to be more effective in preventing drug
resistance. While more than 80% of the cell population was suppressed with the US+Cis combination
treatment, more than 90% of the colony formation was suppressed according to the colony
formation test results. In addition, US+Cis combination therapy caused different cell cycle arrests
in both A2780 and A2780cis cells.

Conclusion:

Ultrasound-based combination therapies show promising results in combating
chemoresistance, and the disadvantages of conventional cancer treatments, such as cancer recurrence,
drug resistance, and high cost, might reduce by the effectiveness of combination therapy of
ultrasound therapy and chemotherapy.
Primary Sjögren’s Syndrome Presenting with Rapidly Progressive
Dementia: A Case Report
Authors: Notas Konstantinos , Papaliagkas Vasileios , Spilioti Martha , Papagiannis Ioannis , Nemtsas Petros , Poulopoulos Athanasios , Kouskouras Konstantinos , Diakogiannis Ioannis , Kimiskidis Vasilios K.
Published: June 2022

Background:

Rapidly progressive dementias (RPDs) are dementias that progress subacutely
over a time period of weeks to months. Primary Sjögren’s syndrome (pSS) is an autoimmune
disease that can affect any organ system and may present with a wide range of clinical features that
may mimic a plethora of medical conditions and, in rare cases, may manifest as RPD. We describe a
unique case of pSS, in which rapidly progressive dementia (RPD) was the first disease manifestation,
and the patient’s radiological and electroencephalogram findings were compatible with Creutzfeldt-
Jakob disease (CJD).

Case presentation:

Here, we report a 58-year-old woman who presented with cognitive impairment
rapidly deteriorating over the last 6 months prior to admission. Brain MRI and EEG were indicative
of CJD. However, CSF 14-3-3 and tau/phospho tau ratio were within normal limits and therefore alternative
diagnoses were considered. Blood tests were significant for positive antinuclear antibodies,
anti-ENA, and anti-SSA and a lip biopsy was consistent with pSS. The patient was started on intravenous
steroids followed by oral prednisone taper, which prevented further deterioration.

Conclusions:

This rare case expands the spectrum of neurological manifestations in pSS and highlights
the importance of considering pSS in the differential diagnosis of RPDs in order to avoid misdiagnosis
and provide appropriate treatment in a timely fashion.
Investigation of Psychoactive Medications: Challenges and a Practical and
Scalable New Path
Authors: Taliaz Dekel , Serretti Alessandro
Published: June 2022

In the last two decades the validity of clinical trials in psychiatry has been subjected to discussion.
The most accepted clinical study method in the medical area, i.e. the randomized controlled
trial (RCT), faces significant problems when applied to the psychiatric field. One of the causes for this
scenario is the strict participant inclusion and exclusion criteria that may not represent the real world.
The inconsistency of the different endpoint parameters that are used in the field is another cause. We
think that psychiatric RCTs’ challenges, together with the underlying complexity of psychiatry, lead to
a problematic clinical practice. Psychoactive substances are currently routinely tested outside of a
formal clinical trial environment. Off-label psychoactive drugs are commonly prescribed, and other
substances, such as herbal remedies, are also regularly consumed. These real-life experiments can
teach us useful lessons. Real-world data (RWD) includes information about heterogeneous patient
populations, and it can be measured with standardized parameters. Collecting RWD can also address
the need for systematically documenting and sharing case reports’ outcomes. We suggest using digital
tools to capture objective and continuous behavioral data from patients passively. New conclusions
will be constantly drawn, possibly allowing more personalized treatment outcomes. The relevant nextgeneration
decision support tools are already available.
Antioxidant and Anti-inflammatory Activities Mediate the Radioprotective

Authors: Das Uttam , Saha Tanmay , Sharma Reshma Kumari , Maurya Dharmendra Kumar , Ray Partho Sarothi , Das Subir Kumar
Published: June 2022

Background:

Ionizing radiation (IR) generates reactive oxygen species (ROS), which leads to oxidative stress that often leads to inflammatory responses in organisms.

Objective:

Trianthema portulacastrum L., a plant commonly growing in India, is rich in antioxidant phytochemicals. This is responsible for scavenging free radicals and may provide radioprotective and anti-inflammatory effects in response to ionizing radiation.

Methods:

The effect of T. portulacastrum extracts was studied in hepatic cells, which are susceptible to radiation-induced damage and in macrophages, which are the primary inflammatory cells of the body.

Results:

T. portulacastrum stem extracts showed efficient free radical scavenging activity in hepatocytes and decreased radiation-induced lipid peroxidation in cell and mitochondrial membranes. Treatment of irradiated cells with T. portulacastrum stem extracts enhanced cell viability at lower concentration and reduced cell viability at higher concentration. Treatment with low concentration of T. portulacastrum stem extract also reduced cellular ROS generation and increased the concentration of cellular anti-oxidant, glutathione. T. portulacastrum extracts also showed remarkable anti-inflammatory properties in macrophages activated by the inflammatory agonist bacterial lipopolysaccharide (LPS). The extract reduced nitric oxide (NO) production and suppressed the expression of inflammatory genes.

Conclusion:

Together, these observations demonstrated a potential radioprotective role of T. portulacastrum extract mediated by both its antioxidant activity on hepatic epithelial cells and its anti-inflammatory activity on immune cells.
Development of High Voltage DC Power Supply from Tesla Coil Using
Hybrid Energy Sources
Authors: Ahmed Amin Arslan , Yaseen Mobeen , Gufran Khan Muhammad , Adnan Muhammad , Mughees Abdullah , Mukhtar Mohsin
Published: June 2022

Background:

High Voltage Direct Current (HVDC) is a well-proven technology used to transmit electricity over long distances by overhead transmission lines or submarine cables. It is also used to interconnect separate power systems, where traditional Alternating Current (AC) connections cannot be used.

Objective:

In this paper, an HVDC supply has been proposed with the Tesla coil using hybrid energy sources such as solar panels, batteries, and AC main supply with an AC-DC converter.

Method:

DC voltage is obtained from various hybrid sources and is supplied to the input of the Cockcroft-Walton (C-W) voltage multiplier circuit through DC/AC inversion.

Result:

The produced HVDC is provided to the Tesla coil to obtain a stable HVDC output. Fractional Order PID (FOPID) controller is used in the system for control purposes to stabilize the output voltage due to load variations. The model was designed in Matlab / Simulink environment. The simulation results show that the proposed design successfully achieved a stable 15 kV HVDC.

Conclusion:

The advantage of the proposed system is the availability of variable output voltage as per load requirement compared to the fixed limited output voltage generated by conventional HVDC systems.

A aquisição de clíticos em português europeu L2 e a Hipótese de Reconfiguração dos Traços
Authors: Pereira Ronan
Published: June 2022

A Hipótese de Reconfiguração de Traços (HRT) sugere que as dificuldades na aquisição de uma língua segunda (L2) ocorrem quando os aprendentes têm de reconfigurar os traços existentes na sua língua materna para apresentarem a configuração que a L2 possui. Este estudo objetivou testá-la relativamente à aquisição dos padrões de colocação dos clíticos do português europeu (PE) L2 e à aceitabilidade de respostas verbais, seguindo Martins (1994), que correlaciona os dois fenómenos com os traços-V fortes do PE. Divididos em dois grupos de proficiência distintos, 21 falantes nativos de espanhol executaram duas tarefas: uma de completamento de frases e outra de julgamento de aceitabilidade de respostas verbais. Diferentemente da literatura na área, a preferência pela ênclise foi menor. Analisando-se os contextos de próclise, não houve homogeneidade na evolução dos padrões de colocação, com aqueles envolvendo a negação realizados em maiores taxas já em níveis de proficiência mais baixos. Uma evolução na aceitabilidade de respostas verbais com o aumento da proficiência pôde ser constatada no segundo teste. Contudo, a análise estatística não demonstrou correlação estatística entre os resultados das tarefas. Concluiu-se que há indícios de validade da HRT, mas investigações futuras devem ser conduzidas para comprovar a natureza dessa reconfiguração.
Leitura de sentenças em alemão por falantes de hunsriqueano: acesso lexical não seletivo e coativação sintática
Authors: Limberger Bernardo Kolling
Published: June 2022

Estudos sobre o processamento da leitura bilíngue/multilíngue têm evidenciado de forma robusta que o acesso lexical é não seletivo, havendo uma busca paralela em todos os subsistemas linguísticos. Esse efeito tem sido replicado nas pesquisas mais recentes nas quais são apresentadas sentenças aos participantes. O contexto de sentença também mostra que pode haver coativação sintática, de modo que as representações sintáticas de uma língua possam facilitar o processamento de estruturas semelhantes na outra língua. De forma geral, tais as investigações incluem línguas hegemônicas e majoritárias. Diante disso, o objetivo deste estudo foi investigar o acesso lexical durante o processamento de sentenças em alemão padrão por falantes de hunsriqueano, língua de imigração alemã falada no Brasil. Foi aplicada uma Tarefa de compreensão de sentenças em alemão. Dois grupos participaram da pesquisa: um composto por falantes de hunsriqueano, o outro por não falantes de qualquer língua minoritária de origem alemã. Todos os participantes estudam alemão como língua estrangeira. Os resultados mostram um efeito do compartilhamento de representações semânticas, fonológicas (acesso lexical não seletivo) e sintáticas (coativação sintática) entre hunsriqueano e alemão no processamento de sentenças em alemão. Por meio dos resultados, visamos contribuir com a pesquisa em línguas minoritárias e processamento da leitura, uma relação nem sempre trivial.
Eye tracking sentences in language education
Authors: Maia Marcus
Published: June 2022

The present study reports and discusses the use of eye tracking qualitative data (static and dynamic gaze plots and heatmaps) in reading workshops in a middle school and in Generative Syntax and Sentence Processing courses at the undergraduate and graduate levels. Both endeavors take the sentential level as the proper object to be metacognitively explored in language education in order to develop innate science forming capacity and knowledge of language. In both projects non-discrepant qualitative eye tracking data collected and quantitatively analyzed in psycholinguistic studies carried out in LAPEX-UFRJ (Experimental Psycholinguistics Laboratory of the Federal University of Rio de Janeiro) were displayed to students as a point of departure, triggering discussions. Active, problem-solving based methodologies were employed with the objective of stimulating student participation. The article also discusses the importance of developing full literacy, epistemic vigilance and intellectual self-defense in an infodemic world.
