Floating PV power generation to balance Brazil's electric system: A sustainable C-free power generation program

Uri Stiubiener, Allan Thomaz Stiubiener, Thadeu Carneiro da Silva

The increase of greenhouse gases (GHG) in the atmosphere forces the power industry to reduce the use of fossils fuels, aiming a Carbon-free energy production. Wind and Solar power plants have been deployed to reduce GHG emissions. However, these technologies occupy big land extensions on a utility-scale. This suggests the use of open water surfaces to install large photovoltaic (PV) floating plants. In this paper, a country-size hydro-solar power generation model is proposed. PV is more predictable than wind power, which already enters the grid without dispatch. This research intends to evaluate if Hydroelectric Power Plants' (HPP) reservoirs can host, near their dams, PV Floating Power Plants (PV-FPP) sized to meet the hydro capacity. Then, use the synergy of hydro and solar sources to run a hybrid generation model. To achieve this goal, we established the state-of-the-art of floating PV generation in Brazil and the world from academic and technical literature. We identified and described the solar characteristics, calculate the PV potential, and simulate a hydro-solar model. This resulted that Brazil can replace its 2020 fossil thermal generation using 50% of the proposed hydro-solar model potential. This model on all countryâ€™s HEPP can add 84.5 TWh/year to the electric system.

R. Sahay

Multicopper oxidases are a large family of blue copper proteins which contain from one to six copper atoms per molecule. Their catalytic centre consists of three domains which involve type-1 Cu, type-2 Cu and a pair of type-3 Cuâ€™s. They include laccases, ferroxidases, ascorbate oxidase, bilirubin oxidase, laccase like multicopper oxidases. MCOs are capable of one electron oxidizing of aromatic as well as non-aromatic compounds with a concomitant four-electron reduction of molecular oxygen to water. These properties make them a valuable tool in various industries (food, textile, pharmaceutical) medicine or environment protection.

Study of Water Discharge in Way Sikabiry Watershed, Liliboy Village, West Leihitu District, Central Maluku Regency

Rudi Serang

The problem of flooding often hits Liliboy Village every rainy season, the problem of flooding is generally caused by poor drainage systems and a bigger impact is the result of damaged watersheds, watersheds that are supposed to be water conservation have undergone land use changes due to human intervention. The result of land use change that can be seen directly is that unpredictable discharge often occurs in the rivers where the watershed is damaged. For this reason, this study aims to determine the scouring pattern that occurs and the amount of water discharge in the Way Sikabiry watershed. This research was conducted in October 2019 in the Way Sikabiry watershed using the Profile (Cross Section) method, which is to place an unsinkable object on the surface of the river for a certain distance and record the time it takes for the floating object to move from one point of observation to another point of observation. have been done. The data used in this research include primary data such as river discharge data and secondary data in the form of watershed maps, measurements and drainage area.The results showed that the scouring pattern that occurred in the Way Sakabiry watershed resulted in a large downstream water flow but high flow rate while in the upstream it produced a small flow rate but a low flow rate and the amount of water discharge in the Way Sakabiri watershed upstream was 0.53095 m3. / second while in the downstream it is 0.73981 m3 / second.

Nashirah Abu Bakar, Sofian Rosbi, Kiyotaka Uzaki

The coronavirus disease (COVID-19) that spreading over worldwide in year 2019, give significant impact towards global economics. In addition, there movement control gives negative impact towards global economic development. Therefore, this study evaluated the impact of COVID-19 towards hotel tourism industry as the most effected sector due to restriction of movement. This study collected data about two companies that involve in hotel tourism industry, both of the companies show negative movement of share price that indicates the declining profit. In the same time, this study developed supply and demand curve simulation regarding the effect of COVID-19 towards hotel tourism industry. The simulation indicates, the decrement of demands creates decrement of price of hotel according to market equilibrium. When the price is reduced, many hotels shrinking their operation that creates lower supply to balance the changes of price. Therefore, at the market equilibrium during COVID-19 outbreak, the hotel tourism industry suffering lower demand and facing lower price for hotel services. This situation creates the hotel industry is dealing with an unprecedented crisis due to the disruption caused by the global COVID-19 pandemic. This study contributes the advancement of literature of COVID-a9 effect towards global economy. In addition, the findings of this study will help government to provide suitable policy in helping hotel tourism industry to survive in current economic situation. This study also helping hotel industry in planning their financial management to make sure hotel industry can be survive until the post COVID-19 situation.

Chlorpyrifos Toxicity in Sheep and Effect of Corchorus Olitorius

Almahdi Alzaroukh Jaber

The organophosphorus compound chlorpyrifos is widely used in southern Libya for pest control. Chlorpyrifos poisoning in sheep is very rare, however accidental poisoning could happen. The parent compound chlorpyrifos is not very toxic until metabolized to the toxic form which known as chlorpyrifos oxon. The delayed clinical signs of chlorpyrifos toxicity increase mortality rate due to the delayed treatment regime. Exposure of sheep to chlorpyrifos mainly develops nervous system toxicity accompanied with other systems toxicity including respiratory, cardiovascular and digestive system. Bowel evacuation by using blend of corchorus olitorius reduces chlorpyrifos toxicity and improves the animal health

Classification of hazardous areas - natural gas installations

An explosive atmosphere can be created by a gas or vapor, dust or even fibers. Methane-based risks dominate the gas generation and distribution sector. The probability that any hazard exists in fuel concentration is determined by the specifics of the system under consideration. For example, a natural gas vent line is much more likely to contain this hazard than a lube oil line - unless, of course, the oil line flange joint is leaking. In this work we present the global assessment of the risks of explosion that inevitably involves the definition and classification of hazardous areas with natural gas due to the presence of explosive atmospheres.

Reliability of prestressed concrete girders design: Comparison between NBR and Eurocode codes

Vinicius Heidtmann Avila, Mauro de Vasconcellos Real

This work evaluates the reliability index of prestressed girders beams of highway bridges designed according to Brazilian and European codes concerning the bending ultimate limit state. A model was used to verify the resistant capacity of the beams in the bending ultimate limit state and to evaluate the live load models proposed by the regulations studied. The bridge studied spans 27.4 meters, and four T section prestressed concrete girders support it. To obtain the reliability index ð›½, the First Order Reliability Method (FORM) was used, which proved to be very fast and efficient. The values collected by the analytical method are validated using the Monte Carlo simulation method. For all cases, the reliability index value was higher than 5.5, showing that the two normative recommendations for the design of girders beams guarantee a very conservative level of safety.

Determination of Stiffness and Hardness of Glasses by using Acoustic Waves Testing

In this study we sought to develop a non-destructive test that uses the propagation of acoustic waves to characterize the stiffness and hardness of flat glasses. For this purpose, three different glass samples were investigated by using acoustic waves resulting from the impact caused by a steel sphere in free fall on the samples surface. As a result, it was found that the glass samples have different vibration frequency and this behavior is associated to the Youngâ€™s modulus and microhardness, values. The values calculated by the ultrasonic transmission method indicated that the increase in stiffness is related to the appearance ofamplitude peaks in the acoustic signal of the samples, attesting to the possibility of the method for characterizing the mechanical properties of glasses used in civil building.

Socioeconomic and Environmental valuation of the Ecosystem Services: A Case Study of from Zoobotonical Park in BelÃ©m, ParÃ¡, Brazil

The value of ecosystem services produced by the natural ecosystem preserved by the Zoobotanical Park of BelÃ©m (ZPB) was estimated based on the population's perception of the existing link between nature and the well-being that is provided to society. The preserved ecosystem provides the population with physical and mental benefits through individual and collective recreation, contemplation of the environment and direct and indirect interaction with animals and plants, as well as knowledge about endangered species and awareness of the need to preserve natural resources in the Amazon. The wood products were estimated by the Net Present Value (NPV), considering a flow of 100 years, as proposed by the Brazilian Institute of Environment and Renewable Natural Resources (IBAMA). Three methods of estimating the NPV were adopted: the value of the carbon stock evolving based on the geometric rate of growth of the diameter of the trees, which resulted in the value of (US$ 145,216.75); the value of the carbon stock without growth rate, with a value of (US$ 66,332.21); and the value of the wood volume of (US$ 34,660.36). The value of ecosystem services was estimated by the Integrated Method of Contingent Valuation and generated the socioeconomic and environmental value for preserving the ZPB of US$ 1,464,527.41 and the value of replacing it with another activity at US$ 1,628,657.59. This amount was more than twice the opportunity cost of the park area for the civil construction market.

The Feasibility of Tax Arbitration In The Brazilian Legal System

Rildo MourÃ£o Ferreira, RosÃ¢ngela de Paiva LeÃ£o Cabrera

The ineffectiveness and slowness of national tax litigation, whether in the judicial or administrative field, is an irrefutable reality. There are several causes of this reality and it is natural that the scant presence of alternative methods of conflict resolution contributes to the perpetuation of this scenario. In this context, the theme under study is tax arbitration in Brazil, with a main cut in the feasibility of the use of arbitration in the resolution of tax disputes. The problem of research is the effective use of arbitration in tax pending. The problem of research is the effective use of arbitration in tax pending. For the development of this work, the deductive method will be used, starting, as can be seen, from the general analysis of arbitration to the specific points that outline the theme. Thus, the study was split into five topics: the status of the taxpayer; Bill No. 4,257/2019; Bill No. 4,468/2020; tax arbitration in Portugal, and finally the feasibility of tax arbitration by the National Tax Code (CTN) and criticism and praise on the part of the doctrine. Thus, the issue of arbitration will be better understood, especially by relating it to the branch of Tax Law, so that the practical implementation of this mechanism can be assessed.

Defense Mechanism of the Immune System Against Hepatitis C Infection

Hepatitis C is an inflammatory process caused by a virus of the genus Hepacivirus. It can be triggered acutely or chronically, the latter being predominant. Chronic hepatitis C (CHC) has a worldwide prevalence in about 1% of the population. Hepatitis C virus infection (HCV) has a diverse genetic variety, which makes its elimination difficult.The present work emerges as a need to understand the mechanisms of defense action against HCV in the human body. The study was based on a literature review, based on research in articles from the SciELO and PubMed platforms, using the descriptors hepatitis C, genetics and immune system associated through the Boolean operators OR and AND. In the end, 15 articles were selected that guided the research of the work. In research, it was found that the virus infection can present in the acute phase or in the chronic phase, in which most cases tend to progress from an acute infection barely detectable by the immune system to a persistent chronic infection. In addition, it was observed that T cells during the chronic phase have their ability to resolve reduced, because, in the acute phase, because of the virus, a large variability does not allow T cells to create neutralizing antibodies or memory cells, therefore, when they present the chronic stage, it causes these defense cells to collapse. Much progress has been made in understanding the immune mechanisms that HCV stimulates, however there are still many gaps that need to be closed.

Article Modelase by Fajate â€“ Direct Sale and manufacture products directly from industry to consumer

Mariana Garcez Catarino

This article works the direct sales market focusing on the Modelase by Fajate project, a form of marketing promoted by companies such as Jequiti, Natura and Avon, which sell and manufacture products directly from industry to consumer. In the current phase of the economy and with the productive reformulation of capital and labor relations, in which the expanded reproduction of capital is sought, the configuration of the globalized economy has led to a new order between the upper and lower circuit. The recent dynamics of the Brazilian economy have influenced the expansion of the two circuits of the urban economy in large Brazilian cities. This business strategy allows the insertion of a wide range of workers, usually urban, integrating into the dominant production model, from a commercial contract. In the understanding of this process, the analysis was imposed in which the accumulation of capital is enhanced in the form of exploitation of the labor force. This articulation, which explains the combined and concomitant existence of different technological stages within the same set of productive processes, makes it indisputable that the criterion of "modern" and "backward" are faces in the same way of capitalist social reproduction. If in the past the direct selling business model was adopted by a few companies, today it is adopted by large and small. In this sense, being extremely important the understanding of the transformations of large companies, which are part of the superior circuit of the economy, with the lower circuit, in their search for expanded reproduction of capital through primitive accumulation, present in many forms of contemporary work. The companies with the direct sales business model that distribute their products through catalogs (Avon and Natura) were presented, demonstrating the peculiarity of each activity in its differentiations within the direct sales system. Adopting the Fajate project to this world of renewing and expanding, in the period of globalization.

Prevalence of Physical Inactivity and Associated Factors: A study with military policemen from MacapÃ¡-AP/Brazil

The present study aimed to estimate the general prevalence of physical inactivity and identify associated factors. Participants were 162 military police officers from MacapÃ¡-AP/Brazil, of both sexes and aged between 23 and 54 years, 25.9% female. The assessment of the level of physical activity was obtained using the International Physical Activity Questionnaire (IPAQ) short version 8. The identification of association factors were obtained by the Socioeconomic Classification Questionnaire of the Brazilian Association of Research Companies (ABEP) version 2018, and by the Body Mass Index (BMI). Descriptive statistics were used to obtain the relative frequency in percentage with a confidence interval of 95%. The association between inactivity and associated factors was performed using the chi-square independence test and Spearman's correlation coefficient with a significance level of p < 0.05. It was identified that 27.8% of the studied sample is physically inactive and is associated with a lower economic class and with the perception of â€œpoor/regularâ€ health. Therefore, approximately three out of ten military police officers in the city of MacapÃ¡-AP/Brazil were classified as physically inactive and these rates are associated with socioeconomic and sociodemographic factors.

Uptake, distribution and biofortification of selenium in Acmella Oleracea (L.) R. K. Jansen

Nutritional biofortification of foods is a promising alternative to reduce Selenium deficiency in the diet of populations. This study evaluated the biofortification capacity of jambu with Se. The experiment was completely randomized with six treatments and five repetitions, in hydroponics. Five doses of Se in the form of sodium selenate (1, 2, 3, 4 and 5 mg.L-1) and the control dose were used. Biometric, macro and micronutrient analyzes were performed, as well as the Se content in the plant parts. The indices of translocation (TrI), tolerance (tI) and Nutrient Use Efficiency (Nue) were estimated. The results were submitted to ANOVA and principal components analysis for the construction of multivariate indicators, in order to specify the regression models. The plant obtained higher agronomic performance when submitted to a dose of 3mg.L-1, with Se translocation above 70%. The tI and Nue indices indicated that jambu reached optimal growth with the dose of 3 mg.L-1 of Se. The results obtained from the regression equation of the multivariate indicators of growth, mass and nutrition indicated that the ideal concentrations of Se varied between 2.77 and 3.36 mg.L-1. The general indicator that captured the entire plant behavior showed that the optimal concentration for biofortification is 2.98 mg.L-1 of Se. The daily consumption of 100 g of biofortified jambu at the indicated dose provides a daily content of 50.13Âµg of Se for the population, a sufficient amount of Se for a balanced diet.

The relation between the Environment and Pandemics

Maria Eurilene Almeida da Silva, Simone da Silva

In late 2019, one of the biggest pandemics of our time, with the power to completely shut down cities, was revealed. This is Sars-cov-2, which spreads very quickly and is transmitted through the air. The Coronavirus is nothing new to the world and warnings about the risk of pandemics have existed for many years, such as that of the 2013 epidemic, made by the WHO (World Health Organization) at a time when there was already alarm about the potential of this virus to cause outbreaks. Pandemics are nothing new to humanity. They were present at different times in history, and this paper aims to present the link between pandemics and disturbances of the natural environment, with emphasis on zoonoses. Some pandemics and their consequences will be briefly exposed, pointing out parallels between them. The study was carried out through the analysis of scientific articles within the specified topic in journals with a high level of reliability, seeking to understand this phenomenon and how to face them. This paper was written while the world was going through the Sars-cov-19 pandemic and was evolving together with the discoveries made day by day by the scientific world. Goals were defined for this paper, such as studying zoonoses and their forms of transmission, analyzing the human factor and how it impacts the environment, and pointing out solutions to solve these problems. This literature review concludes that when humans invade the natural environment and destroy existing relationships in this place, diseases transmitted from animals or from the environment itself can arise, which may or may not cause new pandemics through zoonoses.

An integrated BSC-AHP approach to support the strategic management of small technology companies

As monitoring and strategic management issues become increasingly important in the daily lives of small technology companies, a broadening of the understandings that motivate these changes is extremely useful due to the globalized market they are in. To support these understandings, the Balanced SCorecard (BSC) can be used as a tool that helps strategic management. Within this context, possibilities arise that measurements can be balanced between measures of results and measures that drive future performance. This work presents a hybrid approach that uses KPI (Key Performance Indicator) grouped in the BSC perspectives and which are selected through the AHP multi-criteria method, thus composing a strategic map. The results allowed us to understand that although the proposed approach synthesizes evaluation indices extracted from the literature, it can be parameterized and adapted to different realities and, from that, the relative weights of these indices are calculated using the AHP. This work provides guidance on strategies that can help improve organizational performance beyond the financial perspective.

The green corn development and yield on different summer soil covering plants in the organic no-tillage system

The objective of this study was to evaluate the growth and yield of green corn cultivated under organic no-tillage system on different ground cover plants. The work was developed in the municipality of Domingos Martins, ES, Brazil (20Â° 22' 16.91"S and 41Â° 03' 41.83" W), being arranged in a randomized block design, with six replications and five production systems, consisting of: three soil covers in the organic no-tillage system - with sunn hemp, millet and sunn hemp/millet intercropping; and two systems without straw and with soil tillage - one organic and the other conventional. The double hybrid of corn AG 1051was used, at a spacing of 1.00 x 0.20 m. Evaluations were carried out of stem diameter and plant height, at stagesV5 (five developed leaves), V10 (10 developed leaves) and R3 (milky grains); ear yield with straw and without straw; average weight of 15 ears with straw and without straw; average length and diameter of ears without straw and the percentage of straw. For all agronomic characteristics evaluated, except for length and average diameter of ears without straw and the straw percentage, all the treatments studied were statistically superior to the conventional system treatment. The agronomic characteristic â€œyieldâ€ which is the most important among all evaluated, did not show statistical difference among all treatments under organic system. Therefore, both the organic system without straw and with soil tillage, and the organic systems with straw and without soil tillage using single sunn hemp, single millet and sunn hemp/millet intercropping are possible to be used with good corn yield.

The Influence of Bullying and Malocclusion on the Quality of Life of Adolescents

Objective: To evaluate the association of bullying and malocclusion with the quality of life of adolescents and their families. Methods: 93 young people with an average age of 13.7 years participated in this research which, at the beginning of orthodontic treatment, presented some type of malocclusion that compromised facial aesthetics. The classification of malocclusion was performed by analyzing the initial orthodontic documentation. The impact of malocclusion on quality of life was measured by self-administered questionnaires CPQ (Child Perceptions Questionnaire) and PPQ (Parental Perceptions Questionnaire) which contained questions grouped into 4 domains: oral symptoms, functional limitations, emotional well-being and social well-being. The Kidscape questionnaire was applied to assess the occurrence of bullying. The statistical analysis of the data obtained was by means of summary measures, using the Spearman coefficient and the Kruskal-Wallis tests or Fisher's exact test. The level of significance adopted was 5%. Results: The occurrence of bullying related to malocclusion was observed in 44 young people interviewed, and in 86.36% of these adolescents, the phenomenon happened before orthodontic treatment and had negative consequences on quality of life, especially in the related item of emotional and social well-being. The malocclusions that most related to Bullying were in Class II descending order, followed by Class III and finally the deep overbite. Conclusions: There was an association between the occurrence of bullying, the type of malocclusion and an improvement considered in the quality of life of adolescents after beginning orthodontic treatment.

Linguistic problems caused by anatomical alterations of the hard palate of speakers with Down syndrome

Andreia de Melo Costa Ferraz, Carla Salati Almeida Ghirello-Pires

This study deals with dimensional changes in the hard palate of individuals with Down syndrome; which can cause impairments in the movement of articulators and make it difficult to program the speech sounds that are produced with alterations. Objective: to characterize the production of consonant sounds in Brazilian Portuguese (BP) in a group of young adults with Down syndrome, by correlating changes to the dimensions of the hard palate. Our hypothesis is that this occurs, the greater the speech alterations, the smaller the palatal width and length and the greater the height of the palate. Methodology: data collection was performed using the Speech Assessment Instrument for Acoustic Analysis with transcriptions made by three speech-language pathologists and palatal dimensions were obtained by measuring the participants' plaster models. The correlation coefficient with significance (p

A Machine Learning Approach on the Problem of Corruption

This work presents a step-by-step building of a model that effectively classifies a given municipality as corrupt or not. The output is the likelihood of the city being corrupt, which can be a valuable tool in preventing future corruption cases. This model was constructed to utilize the already existing API from the SÃ£o Paulo State Court of Auditors and was built to deploy monthly reports. The XG Boosting model was the most robust among the many models trained and presented the best AUC score and accuracy.

The Structuring of Goat and Sheep Farming in the Municipalities of the Hinterland of SÃ£o Francisco Pernambucano

This article addresses the research findings on the state of the art of goat and sheep farming in the State of Pernambuco, in the municipalities belonging to the SertÃ£o do SÃ£o Francisco micro region, Afranio, Dormentes, Lagoa Grande, Petrolina, Santa Maria da Boa Vista and OrocÃ³, pointing to the absence of public health policies regarding the situation of municipal slaughterhouses and the urgent need to improve the slaughter and transport of animals, with a view to the health of the population. As an alternative proposal, it brings the regionalization of slaughterhouses, whose structures can meet the specifications and norms of the Federal Inspection System - SIF, reducing zoonotic rates; elimination of contamination vectors; no release of waste in the open; improvement in the slaughter and processing of animals, in addition to positive impacts on the environment, such as efficiency in the treatment of effluents; atmospheric emissions control; reduction of pests and contamination vectors; elimination of sources of pollution from water sources and, above all, the recycling of water, an important asset in the Brazilian semi-arid region. This is a descriptive study, whose approach was of a quantitative-qualitative nature, approaching bibliographic review, field visit and semi-structured interview. Sampling was non-probabilistic for convenience, involving 58 agents of the APL - Productive Arrangement of Caprinovinocultura.

Olusegun Balogun, Victoria Alao, Babatope Pele, L.L Ladokun

Kaplan hydro turbines are adjustable propeller blade turbines that are used in conventional hydroelectric power systems for the generation of electric power. Their mechanical efficiency based on their flexible and wide operating range of flow rates and head depends much on the runner blades and the alignments of the wicket gates. However, design modification of the geometry of the runner blade can be made for the improvement of mechanical efficiency. Computational Fluid dynamics simulation was employed to investigate the improved features of two hypothetical model turbine blades. SolidWorksÂ® software was used for modeling the two categories of the turbine, named model A and model B Kaplan turbines. Model A has a short blade length of 130 mm twisted at an angle of 300, and its blade was varied from 2 to 6 blades. Model B has a longer blade length of 150 mm twisted at an angle of 300, and its blade was varied from 2 to 6 blades. The governing equations, which include continuity and momentum, were discretized using the Finite Volume method. The result shows that an increase in blade total surface area, as a result of an increase in blade length or blade number, increases the power output of the Kaplan hydro turbine.

Marketing Communication Strategies: A Study in a Civil Construction Company in Gurupi - To

The constant changes in customers' wants and needs require companies to take a more aggressive position in the market to face competitors. For this, companies need to adopt marketing strategies that enable adding value to their products and / or services, since, competition is more fierce, the desire for leadership in the market is the new trophy and staying alive within that market is not more a matter of luck, it is a question of knowledge and attitude. Marketing communication planning is important for the company to understand the market in which it operates and (or) intends to operate, the target audience it intends to reach and what message it wishes to convey. In view of this, the focus of this work was to analyze the marketing communication strategies of a company in the civil construction sector of the Gurupi - TO trade. The research was characterized as descriptive, exploratory and as a case study. The data were collected through an interview with the manager of the studied company and it was concluded that the organization uses few communication marketing strategies, as the company communicates with customers only by telephone (always), e-mail ( always), television (sometimes) and Instagram (always), does not have an annual value directed to the communication area and there is no specific person to prepare the plan and evaluate the return (feedback) of the marketing strategies implemented in the organization.

Depression in the Pandemic: The Impacts on Mental Health During the COVID-19 Contagion in Brazil

The aim of this study was to investigate the symptoms of depression resulting from social distancing and its impacts on the Brazilian population during the COVID-19 pandemic. Methodologically, this is a qualitative-quantitative, cross-sectional survey, carried out online. Data were collected through a questionnaire that initially contained sociodemographic information, followed by information about depressive symptoms. The questions were constructed considering the concept of â€œmental health wavesâ€, depicting the mental health demands presented at the respective moments of the pandemic. The sample consisted of 632 participants, and the prevalence of depression in the present study sample was 44.9%, with no statistically significant differences between genders. Regarding education, the postdoctoral degree was presented as a protective factor of depressive symptoms (OR=0.03, 95% CI=0.01-0.8). Factors significantly associated with anxiety were age between 50 and 54 years (OR=2.573, 95% CI=0.9-6.9), fear of dying (OR=1.86, 95% CI=1.19-2.89), loneliness (OR=5.32, 95% CI=3.40-8.31), irritability (OR=3.47, 95% CI=2.25-5.34), an infodemic (OR=1.70 95% CI=1.09-2.67), financial difficulties (OR=2.22, 95% CI=1.40-3.54), and boredom (OR=1.66, 95% CI=1.03-2.66). The results of the present study highlight the need for public health interventions aimed at reducing the psychological consequences related to the COVID-19 pandemic and social isolation measures, including increasing social support and strengthening social connections.

Environmental Racism has Colour: A Look at the Fishing Territory

Artisanal fishing, considered a millenary activity, suffers with deep transformations in the face of coastal developments. Factors that constitute the environmental vulnerability of artisanal fishermen from the "economic development". This being said, this study aims to understand environmental racism in fishing territory, especially the Ilha de MarÃ©, located in Salvador - BA/BR. The resistance and the defense of a Healthy and Sustainable Territory (TSS) for the preservation of its natural resources were important elements brought about in this process. The method was based on action research and popular education. The methodological path was based on meetings between researchers from the Oswaldo Cruz Foundation (Fiocruz) and the community, in order to capture the perception of the residents of the Island about health, environment and work, given the impact of the Industrial Complex and the Port of Aratu. As a result, it was observed that environmental racism affects not only the natural environment, but also the living, health and working conditions of the fishing population. Thus, the need for organization and mobilization of the people involved in the search for social rights, improvement of health and work conditions, preservation, demarcation of fishing territories and the fight against environmental racism.

Drought Diagnosis in the Municipality of Itaberaba-Ba and the Potential Impacts for Pineapple Growing

This work presents a diagnosis of the incidence of drought in the municipality of Itaberaba-BA, with a view to evaluating the behavior of rainfall for the last 40 years (analyzing the possible consequences for the cultivation of pineapple in the region), and for the changes that the projections future climate points. Daily historical data of precipitation (mm), maximum and minimum temperatures (ÂºC) were used. To characterize drought situations, the Standardized Precipitation Index (SPI) was used, which quantifies the deficiency of precipitation in different time scales, and future data came from the PROJETA Platform using the climate scenario: RCP 8.5, continental, HADGEM2-ES. The treatment of rainfall data showed that the wettest period lasted from November to March, which is the best period to plan pineapple planting. As inferences: a) There is an increase of approximately 530 ha of harvested area, when the SPI18_May transcends its classification of incipient humidity to moderately humid, in more than 95% of the years; b) At each unit increment of SPI18_May, pineapple yield tends to increase quantitatively by 6,952 kg/ha, in the rainfed system for the municipality of Itaberaba; and c) For future projections, from 2020 to 2060, it is believed that there will be no expressive change in the responses of harvested area and yield, as the climatic behaviors of drought for the present climate and future climate, when confronted, do not undergo substantial variations.

Chinese Studentsâ€™ Dilemmas of Neoliberal Storm in Ivory Tower: A Top-down Reasoning and Bottom-up Solutionsâ€™ Proposal

MA Yiran

With rapidly developing globalization and modernization, Chinese university studentsâ€™ values and competencies have been discursively shaped in the prevailing neoliberal Ivory Tower. Also, influenced by Confucian values, Chinese university students regard higher education as the most significant chance of promoting their social class. Firstly, with the economic history approach, this study illustrates the cultural-acceptance process of neoliberalism in China. Secondly, with the top-down reasoning, this study critically analyses Chinese university studentsâ€™ dilemmas like heavy competitive pressure, weak socio-emotional skills, limited critical analysis and inadequate creativity in examination-oriented and teacher-centered higher education resulting from social stratification pressure of low socio-economic status families for social stratification, the World Class University movement, and broader political, economic contexts. Furthermore, in terms of â€œgloncal agency heuristicâ€ (Marginson & Rhoades, 2002), and a multi-level stakeholder analysis about the micro, meso, and macro-level educational challenges in the Chinese higher education system, this paper develops a bottom-up solutionsâ€™ proposal about student-centered and self-learning constructivism strategy. Moreover, the proposed social-emotional skills and transversal competencies for Chinese university students involve critical thinking, self-efficacy, interpersonal, intrapersonal, cognitive, intercultural communicative competence, empathy, cosmopolitanism as global citizens, and a common identity. In conclusion, the proposed bottom-up solutions are as follows: (1) SDGs-based liberal arts curriculum for the public value construction; (2) student-centered pedagogy for Chinese studentsâ€™ autonomy formation; (3) civic-life engagement for â€œwhole personâ€ cultivation. This constructive proposal aims at facilitating students to overcome competitive status anxiety independently with inner motivation, global employability, and finally realize social mobility through transformative higher education.

A Case Study of Teachersâ€™ Identity in Chinese Online Shadow Education Institutions

MA Yiran

Dating back to 2021, thanks to information and communications technology (ICT), most educational institutions have accumulated the experience of sustainable operation under the coronavirus pandemic. In particular, K-12 shadow education has quickly responded to the digital transformation of online teaching scenes to continue teaching plans and realized a compelling connection between online and offline courses. Even when facing a crisis again in the future, it would be possible for students are to deal with it calmly by continuing to utilize the online platform and technical tools built by educational informatization in this pandemic. However, it is also notable that although online shadow education has embraced its peak development and the rapid penetration of the sinking market under the catalysis of the coronavirus pandemic, it has also exposed many defects of itself. For instance, the improvement of online interaction for ideal teaching effects, and the guarantee of stable transmission of the platform, are still the directions that online shadow education urgently needs to explore and constantly polish. Therefore, this research, paying attention to the status quo and influencing factors of online teacher identity, will facilitate ICT teacher education, boost teaching quality, enhance evaluative standards for selecting online shadow education, and provide more guarantee for students and parents. Through semi-structured in-depth interviews and case analysis of two teachers in online shadow educational institutions, this paper analyzes the current situation and influencing factors of online shadow education teachersâ€™ identity from the macro, meso, and micro dimensions, in terms of four significant levels of vocational identity, professional identity, environmental identity, and personal identity. The findings of this study would empower online teachersâ€™ professionalism and career development for post-pandemic shadow education, which will also facilitate the studentsâ€™ engagement in distance private schooling at the same time.
