Authors: Kashiparekh Kahni
Published: March 2021

With the rise of new age media, social media marketing has become one of the most powerful tools in all marketers’ arsenal, and brands’ social media pages have become a way for companies to expand their awareness and customer base. In this paper, factors that attract a social media user to “follow” and engage with brands have been studied, namely, the content and tone used by brands on their social media, online brand communities for the brand, and the brand’s online activism have been identified as some of the important factors. For determination of results, factor analysis through principle axis factoring and varimax rotation has been done on SPSS v23.0. The results indicate that users care about whether brands take a stand on social, economic and political causes, and brand activism is therefore the most important factors for Gen-Z and Millennials in their decision to turn into brand followers. At the same time, users also want to feel like they belong to the brand’s ecosystem and that the brands look at them as important stakeholders, which is achieved through brand communities.

This study will help marketers plan their social media marketing activities more effectively so as to give users what they want, and in turn increase their online reach.

Authors: D. Suresh, S. Satheesbabu P. Gokulakrishnan,
Published: March 2021

Crowd-sourcing is a prototype where persons cum organisations acquire facts such as ideas, micro-tasks, financial, vote casting associated to items and offerings from individuals of large, open and rapidly-evolving nature. It entails utilization of web acquired and distribute work between members to get a collective result. The software of classification tasks in crowd-sourcing is a counter step due to the inclined reputation of crowd-sourcing market. Dynamic Label Acquisition and Answer Aggregation (DLTA) crowd-sourcing framework accomplishes the classification assignment in a promising manner. But most of the current works are now not in a position to supply an budget allocation for labels due to the fact they do  not make the most the Label inference and acquisition phase. In addition, label mismatch and multi-label tasks are the different issues encountered in the current works. To overcome, it is proposed to undertake Random Forest Algorithm (RFA) for classification in crowd-sourcing. The goal of this work is to enhance the crowd-sourcing classification task efficiency with Dynamic Resource Algorithm. RFA is activated by means of developing a multitude of  decision tree at training time and consequences with the training and it applies a bagging approach to produce the last end result with more accuracy.

AN EFFICIENT NOVEL APPROACH FOR SOCIETAL COMMUNICATION OF Q&A COMMUNITY SYSTEM USING TOPIC MODELING TECHNIQUES
Authors: A.P Siva kumar Venkateswara Rao P,
Published: March 2021

The emerging trend in technical research is to use customer-generated data collected by community media to probe community opinion and scientific communication on employment and care issues. This review of the collected data, the launch of a question-and-answer social website, is a separate stack for exploring the key factors that influence public preferences for technical knowledge and opinions. by means of a web search engine, topic modeling, and regression data modeling, this study quantified the effect of the response textual and auxiliary functions on the number of votes received with the response. Compared to previous studies based on open estimates, the model results show that Quora users are more likely to only talk about technology. It can fail when the keywords in the query do not match the text content of large documents that contain relevant questions of existing methods, ie. CNNMF and NMF, as well as some restrictions are not enough. Also, users are often not experts and provide ambiguous queries leading to mixed results and encountering problems with existing methods. To address this problem, in this article we propose a Hadoop model, distributed using semantics, non-negative matrix factorization (HDiSANNMF), to find topics for short texts. It effectively incorporates the semantic correlations of the word context into the model, where the semantic connections between words and their context are learned by omitting the grammatical view of the corpus. The researchers are trying to reorganize the main results and present modern techniques for modeling distributed themes to address technologies and platforms with increasing attributes, as well as how much time and space it takes to generate the model. This document briefly describes the structure of public questions and answers around the world and tracks the development of the main topics Housing and employment opportunities for next generation technologies in the world in real time.

Physiology n. depressoris. Relationship n. depressor to vasomotor centers
Authors: Fofanov L. L.
Published: March 2021

The central apparatus of the human body, on which the equal distribution of blood throughout the body depends, - the heart, is not an organ completely independent in its functions in the body, but is always under the strict control of the nervous system. At the present time it is well known that there are nerves that change the activity of the heart - its rhythm either towards acceleration or deceleration, and that the heart is equipped with a special nervous mechanism, with the help of which it can change blood pressure, if the latter is very high in the beginning of the aorta, or if the ventricles of the heart are full and thus the emptying of the ventricles is difficult. This nervous apparatus is represented in the animal organism as a so-called depressor nerve. The action of the depressor nerve consists in the fact that when it is excited and its excitement, the total blood pressure drops sharply and the heartbeats are significantly slowed down. Both effects are aimed at allowing the ventricles of the heart to empty more easily from their contents and in this way to reduce the work that the heart would have to do. T. about. this nerve is, as it were, a natural regulator for the heart, as it is called. Regarding why a decrease in blood pressure occurs during irritation of a depressor, the opinions of physiologists are still not the same. Most physiologists with Suon in the head see in a decrease in pressure, in case of irritation of a depressor, the result of oppression of the center of vasoconstrictors, however, there is another view, which, however, has few defenders, according to which the drop in pressure, due to the stimulation of the center of the depressor, is due to irritation. T. the question of the influence of a depressor on one or another center is still open, and the existence of the very center of vasodilators is clearly questioned by some authors; and I think that my attempt to clarify this issue, undertaken at the suggestion of the highly respected teacher, my prof. NA Mislavsky will be, although not entirely new, but far from superfluous.
Effect of botulinum toxin on lower vertebrates in connection with changes in the nervous system of them
Authors: Favorsky A.
Published: March 2021

In 1897, V. Ermengem established that the well-known phenomena of botulism in the clinic owe their origin to a special pathogenic saprophytic bacillus discovered by him, bacillus botulinus. He stated that the pathogenic action of this bacillus depends on that toxic principle, which lies in its protoplasm and those environments, strictly anaerobic, where it is able to develop. Introducing the culture of this bacillus or its pure toxin into the animals' mouth or under the skin, he became convinced that some of them are very sensitive to this poison, others are less susceptible and, finally, others are completely immune. The first to include rabbits, mice, guinea pigs, monkeys, which died with typical phenomena of botulism from the minimum doses. The second group includes cats, pigeons, and rats, which perished from more high doses; to the third, he classifies dogs, hens and,. mainly frogs, fish, cyprinus, which, according to him, have complete immunity. However, establishing the fact that animals are different in relation to the pure toxin bac. botulinus, V. Ermengem often does not provide definite data on the lethal minimum dose of the toxin for these animals. There is an exact indication of the dose of the toxin only for pigs and rabbits, and partly for a cat.

Combatiendo la evasión fiscal e incrementando la transparencia financiera en tiempos del COVID-19: El caso de Paraguay
Authors: Pierri Gastón , Best Michael , Blanco Roberto , Monreale José
Published: March 2021

Reducir la evasión fiscal es uno de los principales objetivos de los países, especialmente de los menos desarrollados y con menores recursos. La literatura ha estudiado distintas herramientas para lidiar con la evasión fiscal, aunque sin resultados concluyentes. Además, la mayor parte de la evidencia proviene de países desarrollados. Para contribuir a llenar ese vacío, este documento presenta evidencia acerca del impacto de los programas de auditoría en la reducción de la evasión fiscal en Paraguay. Utilizando la metodología de diferencia sintética en diferencias se evalúa el efecto de las auditorías en las ventas declaradas, en la reducción de las compras y el pago de impuestos de las empresas durante el período 2018-2019. Además se presentan resultados del uso del tablero de impuestos que identifica las discrepancias en las declaraciones de las firmas. Los hallazgos muestran que las auditorías son efectivas cuando se trata de reducir la evasión fiscal, y que los tableros pueden orientar criterios para un control fiscal más eficiente, particularmente importante en tiempos de COVID-19. De esta manera se demuestra que en los países menos desarrollados las acciones de control gubernamental son claves para mejorar la recaudación fiscal.

Published: March 2021

The goal of development assistance is to deliver measurable results. At the Inter-American Development Bank (IDB), the Development Effectiveness Framework (DEF) was adopted to enhance the likelihood this goal is met. The key objective of this analysis is to enhance our understanding of the role the set of tools and processes adopted at the IDB, from project design to completion, play in the assessment of a projects success and effectiveness. Specifically, we are interested in teasing out the role different dimensions of project design, assessed through the Development Effectiveness Matrix (DEM), and execution performance indicators, as per the Project Monitoring Report (PMR), have on the delivery of effective and successful projects measured through the Project Completion Report (PCR) methodology implemented at the IDB. We also explore the validation process of PCRs and delve into the effectiveness analysis at the level of specific objectives and result indicators, identifying key pitfalls associated with objectives not being met. Overall, our findings provide strong validation for the DEF and its tools. We find robust evidence for the importance of the quality at entry assessment conducted through the DEM. In particular, the quality of the results matrix at approval is a strong determinant of project success and effectiveness at closure, and the quality of the Evaluation Plan is strongly associated with the effectiveness of a project. In terms of execution performance, our analysis finds that, on average, projects that execute a lower share of their approved loan amount, are put on Alert, or are classified as a Problem, in its first three years of execution; and projects that experience a higher share of their outputs discontinued, with respect to their first results matrix, are most likely to be ineffective in achieving their objectives and will likely be rated as unsuccessful.

Renewable resources are complementary in nature so the weaknesses of one can be overcome with the strength of other. The factors such as climate condition and weather are unpredictable, more for wind than compared to solar sources. The complementary nature of wind and solar sources motivates us to hybrid wind-solar power plant concept. The major problems like environment hazards, depletion of fossil fuels can be overcome by using hybrid power station. With the help of grid interconnection, the energy can be supplied to the remote rural areas and the emission of carbon and other harmful gases can be reduced up to 80% to 90%. This paper focuses on the optimal combination of renewable energy resources that could electrify the area under study. This paper also highlights the village details, energy resources available in region under study and the predicted load assessment. The various power output equations of wind power and solar power has also been discussed. The overview of the Homer software that was used for simulation purposes has also been discussed in this work.
Switching Regulation in the Control of 5-Phase Permanent Magnet Synchronous Motor Fed by 3×5 Direct Matrix Converter
Authors: Ishaq Muhammad , Che Yanbo , Ullah Kifayat
Published: March 2021

Matrix converter is an AC-AC direct power converter comprising of an array of bi-directional switches. It does not require an intermediate DC-link and allows sinusoidal output waveforms with varying amplitudes and frequencies. The configuration of these bi-directional switches decides the number of inputs and outputs of the matrix converter. This research uses a direct matrix converter (DMC) as a phase-changing device that can convert a three-phase AC voltage into a 5-phase AC voltage. The DMC is modulated with the model predictive control algorithm. The output of DMC is fed to a five-phase permanent magnet synchronous motor (PMSM). The model predictive current control technique for DMC is carried out by developing a mathematical model of an input filter and PM motor used as a load. The predictive control of DMC results in sinusoidal output current, and it also enables the frequency variation in the output current. This frequency variation is useful in controlling the speed of the motor connected to the load. After controlling the 5-phase motor, the switching frequency regulation is done to observe its effect on the motor's stator current waveforms. Switching frequency regulation helps to limit the unnecessary switching of DMC. We developed a MATLAB-based Simulink model to study PMSM, and detailed results are presented. The results show that switching regulation can significantly reduce the switching frequency without compromising the current waveform quality.

Published: March 2021

Power losses are the most critical metrics in power converters analysis and has a significant impact on economic and technological assessments due to its sufficient approximation. This article aims to prove that the power losses (Switching & Conduction losses) are very low in low frequency switching modulation in contrast with high switching frequency modulation. Two switching modulation techniques Phase Disposition (PD-multi carrier-based pulse width modulation at high switching frequency) and Selective Harmonic Elimination Pulse Width Modulation (SHEPWM-fundamental switching frequency) are considered for the power loss assessment in 15-level reduced switch asymmetric multi-level inverter. This work proposed a simplified model for calculation of switching losses in multilevel inverters using MATAB SIMULINK. Further, the thermal model of the proposed inverter is implemented on PLECS for analyzing the power losses. The comparative analysis of switching and conduction losses of the proposed inverter with the PLECS thermal model and MATLAB precise models are integral part of this research.

Published: March 2021

The automotive industries are looking for many ways in order to reduce the weight of the vehicle. Also, light vehicles are better at handling and also efficiency of the vehicle is more. Heavy weighted vehicles as compared to light weighted vehicles produce a large amount of harmful gases like CO2 and SO2. There are many alternatives in order to reduce these harmful gases. One such alternative is using compressed air to power the vehicle. So, in this research work the main aim of the project is to design, fabricate and test a single seated vehicle that runs on an alternative source of energy, specifically compressed air. A pneumatic rotary engine having a maximum pressure of 7 bar is used in designing the above air compressed vehicle. In order to achieve speed of 30-40 Km/hr, two air cylinders are used in this design. From this study it can be concluded that using less dense and higher volume tank it is possible to increase the output velocity of the vehicle. The findings of this research can be used for further development of air compressed vehicle.

Authors: Suryadi Aris , Notosudjono Didik , Suhendi Dede , Rachmat Ubaedy
Published: March 2021

Electrical energy is a basic human need and its use continues to increase, it is necessary to seek and utilize alternative to meet these energy needs, among others, by combining wind energy and solar energy. In its application, this hybrid power plant requires a battery as a storage medium and a controller as a regulator. There is a controller designed for the direct control type, where the electrical energy from the power plant to the hybrid source will not be directly channeled to the battery but through the MOSFET first, so that charging and disbursement of power consumption on the battery can be regulated. When the battery is fully charged, the system voltage controller will read the parameters to be adjusted and will disconnect the hybrid power source to the battery to prevent overcharge. The controller switches and regulates battery power usage to the load. The battery charging control system uses the PWM method using a MOSFET as the driving circuit and the ATMega 32 microcontroller as the system controller.

Background: COVID-19 vaccine development is proceeding at an unprecedented pace. Once COVID-19 vaccines become widely available, it will be necessary to maximize public vaccine acceptance and coverage.

Objective: This research aimed to analyze the predictors of COVID-19 vaccine acceptance in Russia.

Methods: A cross-sectional online survey was conducted among Russian adults from September 26th to November 9th, 2020. Predictors of the intent to take up COVID-19 vaccination were explored using logistic regression.

Results: Out of 876 participants, 365 (41.7%) would be willing to receive the vaccine if it became available. Acceptance increased for a vaccine with verified safety and effectiveness (63.2%). Intention to receive the COVID-19 vaccine was relatively higher among males (aOR=2.37, 95% CI 1.41-4.00), people with lower monthly income (aOR=2.94, 95%CI 1.32-6.57), and with positive trust in the healthcare system (aOR=2.73, 95% CI 1.76-4.24). The Russian people were more likely to accept the COVID-19 vaccine if they believed that the vaccine reduces the risk of virus infection (aOR=8.80, 95%CI 5.21-14.87) or relieves the complications of the disease (aOR=10.46, 95%CI 6.09-17.96). Other barriers such as being unconcerned about side-effects (aOR=1.65, 95%CI 1.03-2.65) and the effectiveness and safety of the vaccination (aOR=2.55, 95%CI 1.60-4.08), also affected acceptance.

Conclusions: The study showed the usefulness of the health belief model constructs in understanding the COVID-19 vaccination acceptance rate in the Russian population. This rate was influenced by sociodemographic and health-related characteristics, and health beliefs. These findings might help guide future efforts for policymakers and stakeholders to improve vaccination rates by enhancing trust in the healthcare system.

Este é um estudo qualitativo, exploratório e descritivo realizado em Teresina-Piauí, em 2019, com o objetivo de discutir as perspectivas de família(s) dos profissionais que fazem parte da Estratégia Saúde da Família numa Unidade Básica de Saúde. Participaram 12 profissionais (1 médico, 3 enfermeiros, 2 agentes comunitários de saúde, 2 técnicos de enfermagem, 2 técnicos de saúde bucal e 2 dentistas), aplicando-se um roteiro de entrevista semiestruturado. A análise dos dados foi fundamentada no método de análise de conteúdo. Duas categorias empíricas emergiram: “Perspectivas de família(s) sob diferentes olhares” e “Dinâmica do cotidiano no processo de trabalho”. Os profissionais compreendem que a família é um universo que transcende a perspectiva sacralizada e idealizada baseada apenas no amor entre seus membros, apreendendo, a partir dos seus processos de trabalho que novas constituições familiares se consolidaram e que tal feito implica em novas posturas na assistência das equipes da Estratégia Saúde da Família, em busca de um cuidado integral e de qualidade, contudo, destaca-se como um desafio a ser enfrentado a dinâmica e cotidiano de trabalho.

Published: March 2021

Devido às mudanças do mercado e à necessidade do governo de fornecer educação aos cidadãos, o Brasil experimentou um processo de crescimento no ensino superior. Assim, de forma crescente, com transformações competitivas e constantes, as demandas por serviços de qualidade tornaram-se um denominador comum nas Instituições de Ensino Superior (IES), o qual expôs a necessidade de otimizar a gestão para que as instituições públicas melhorem seu desempenho em benefício dos estudantes. Ao contrário das outras empresas, que têm como objetivo a satisfação, essas IES geralmente percebem a satisfação como um meio para um fim. Ou seja, estudantes satisfeitos são estudantes leais. Assim, nesta pesquisa, o Modelo Europeu de Satisfação (ECSI) foi aplicado a 1.581 estudantes de 23 universidades públicas e livres no Brasil. Como resultado, observou-se que a satisfação é um fator determinante da lealdade. Entre os determinantes de satisfação, observou-se que a imagem, o tratamento das reivindicações e o valor percebido são os mais representativos. Dessa forma, a gestão eficiente da imagem da IES pública, o tratamento adequado das reivindicações dos estudantes e a percepção de que o investimento de esforço e tempo gerará ganhos futuros têm uma influência positiva e significativa na continuidade do aluno no mundo.

A universidade possui um histórico pautado na contribuição para avanço do conhecimento e da tecnologia no contexto socioeconômico de um país, por meio do ensino, da pesquisa e da extensão. O conhecimento gerado pelas pesquisas realizadas por alunos e pesquisadores pode ocasionar a interação com diferentes atores, entre eles as empresas, acarretando a transferência do conhecimento produzido na universidade para o mercado. Diante disso, este artigo teve como objetivo analisar de que forma ocorre a interação universidade-empresa a partir dos casos da Universidade Estadual de Campinas (Unicamp) e da Universidade do Vale do Rio dos Sinos (Unisinos). O método utilizado possui abordagem qualitativa, de natureza exploratória, e caracteriza-se, em termos de delineamento, como um estudo de caso, possuindo como elementos duas Instituições de Ensino Superior brasileiras. Para coleta de dados, além da pesquisa bibliográfica e documental, adotou-se a entrevista semiestruturada realizada com gestores e pesquisadores das universidades. Na análise dos dados, foi empregada a análise de conteúdo, com o tratamento por meio do software NVivo®. Os principais resultados evidenciam que empresas e universidades necessitam compreender que é preciso atuar conjuntamente na pesquisa tecnológica colaborativa para que os recursos financeiros investidos pela iniciativa pública ou privada não somente sejam aceitos como artigos publicados em revistas científicas, mas também se transformem em inovações tecnológicas difundidas ao mercado.

Authors: Bandeira Herivânio Torres , Callado Aldo Leonardo Cunha
Published: March 2021

Este trabalho teve por objetivo investigar o nível das relações estabelecidas entre fatores contingenciais de empresas pertencentes ao setor de construção civil da Cidade de Recife (PE) e a importância atribuída pelos gestores aos indicadores de desempenho classificados nas perspectivas do Balanced Scorecard (BSC). Nessa perspectiva, foi analisada a importância atribuída aos indicadores de desempenho, sob a ótica da teoria da contingência. Quanto aos procedimentos metodológicos, utilizou-se como instrumento de coleta de dados o questionário, que foi aplicado junto a gestores de 20 empresas do setor da construção civil localizadas na Cidade de Recife. Para análise dos dados coletados foi utilizado o teste não paramétrico coeficiente de correlação de Spearman, com o auxílio do software STATISTICA for Windows. A análise dos resultados evidenciou poucas relações significativas entre as características dos gestores com indicadores de desempenho, sendo a relação da variável faixa etária com o indicador desperdícios a única a alcançar magnitude forte. Também foram evidenciadas algumas relações significativas entre as características das empresas e os indicadores de desempenho, sendo as relações da variável prioridade estratégica com os indicadores (pontualidade de entrega, flexibilidade de volume operacional, entregas no prazo, satisfação dos empregados e gestão de risco) as únicas a apresentarem magnitude forte. As contribuições da pesquisa podem se realizar no campo de estimular outros pesquisadores que pretendam desenvolver estudos correlatos em outras localidades e até mesmo em outros segmentos de mercado, assim como por servirem como parâmetro para reflexão das empresas do setor pesquisado acerca do tema aqui discutido.
