ENTRE MIASMAS E O ANOPHELES: UMA BREVE HISTÓRIA DA MALÁRIA NO ALVORECER DA REPÚBLICA EM MANAUS (1898-1904)
Authors: Silva Márcio de Carvalho e , Barbosa Keith Valéria de Oliveira
Published: July 2021

Os primeiros anos de República em Manaus foram movimentados devido às alterações significativas na paisagem da cidade, como a construção e o nivelamento de ruas e o aterro de igarapés. Esses acontecimentos foram propiciados graças ao acúmulo de capital advindo da comercialização do látex, a ponto de a cidade ficar conhecida como a “Paris dos Trópicos”, dada o cosmopolitismo que a cidade assumira com a economia da borracha. Ao mesmo tempo em que se expandiu enquanto cidade, Manaus também assistiu a expansão de doenças como a malária, esta que protagonizou sucessivas epidemias no período da Belle Époque. No presente artigo iremos  abordar como a doença ganhou uma visibilidade diferenciada em relação à época provincial, destacando-se nos relatórios de autoridades sanitárias e dos governantes no alvorecer da República em Manaus. Para tanto utilizaremos a técnica da análise de discursos de modo a verificar as mudanças e permanências no entendimento sobre a doença entre 1898 e 1904. Ao mesmo tempo, iremos verificar como o recrudescimento da doença na cidade traz, à reboque, novos embates entre os médicos amazonenses em relação à etiologia e à transmissão da moléstia, isto é, a partir da ideia do mosquito enquanto vetor nos primeiros anos do século XX.

The gender identity effect in hypothetical transgressions: a mixed approach exploring undergraduates' attitudes toward transgender individuals
Authors: Maftei Alexandra , Cojocariu Narcisa-Anamaria , Holman Andrei Corneliu
Published: July 2021

The present study explored the relationship between attitudes toward transgender individuals and the judgments people make in transgression scenarios involving transgender and cisgender individuals of different ages in a sample of 184 Romanian students. We used a mixed-method approach (quantitative and qualitative) and tested the effect of gender identity (cisgender or transgender) on participants' punishments in a hypothetical transgression (i.e., theft). In hypothetical transgressions involving preadolescent transgender and cisgender agents, results suggested no differences in participants' theft punishments. However, adult cisgender transgressors received significantly harsher punishments compared to transgender transgressors. Our qualitative analyses (N=736) suggested that the most frequent categories of responses justifying the punishments confirmed the importance of the agent's age. Our findings suggested no significant associations between participants' gender and reported the previous contact with an LGBTQ member and the punishments they chose for child and adult transgressors. Results are discussed in light of their implication in the contemporary, highly LGBTQ intolerant Romanian context.
Freedom or Arbitrariness: A Social and Philosophic Analysis
Authors: STEZHKO Zoia , HRYSHCHENKO Nina , KULTENKO Valentyna , SAVYTSKA Inna , SUPRUN Alina , RUSKO Nadiia
Published: July 2021

The freedom theme has always been in the centre of life and philosophical and political discourse. Freedom is one of the magic words causing many positive emotions in everyday life. Certain social and philosophical studies highlight the ways of replacing traditional and, sometimes, spontaneous absolutization of human freedom at an empirical level of social consciousness. It lies in achieving desired results and being entitled to choose what to achieve. The difference between these “formulas” is obvious. In the second case, one can observe one's acceptance of certain restrictions of freedom due to social reality and understanding that it can only be fully realized through self-restraint. However, one needs to come to such conclusions on one’s own. Practice shows that the categorical power of authorities in terms of citizens’ duties mostly leads to opposite results. Therefore, more than ever, it is essential to develop a permanent, well-developed, multi-level humanitarian programme for working with the population based on social and philosophical studies. The state needs to build the “net” of permanent special state-owned institutions since it will improve the quality of public administration, pave the way for tolerance and successful compromises. The ultimate goal of this article is to form a conscious (rational) civic position and self-determination as a result of one’s full awareness of responsibility for one’s decisions.

Published: July 2021

The centrifugal compressor design involves the use of approximate engineering techniques based on mathematical modeling. One of such techniques is the universal modeling method, which proves to be practically applicable. Having generalized a series of CFD calculations, we used a mathematical model in the latest version of the compressor model to calculate flow parameters in vaneless diffusers. The diffuser model was identified based on the results of experimental studies of average-flow model stages carried out at SPbPU. The model is also used to calculate Clark low-flow centrifugal compressor stages with narrow diffusers with a relative width in the range of 0.5--2.0 %. For these stages, the developed mathematical model showed insufficient efficiency, since the dimensions of the diffusers go beyond the limits of its applicability. To solve this problem, we calculated a series of vaneless diffusers with a relative width in the range of 0.6--1.2 % in the ANSYS CFX software package. Relying on the results of CFD calculations, we plotted the gas dynamic characteristics of the loss coefficients and changes in the flow angle depending on the flow angle at the inlet to the vaneless diffuser. To process the calculated data, the method of regression analysis was applied, with the help of which a system of algebraic equations was developed that connects geometric, gas-dynamic parameters and similarity criteria. The obtained equations are included in a new mathematical model of the universal modeling method for calculating the flow parameters of vaneless diffusers. Comparison of the calculated gas-dynamic characteristics according to the new model with experimental data showed the average error of modeling the calculated (maximum) efficiency equal to 1.08 %
Numerical Solution to the Contact Interaction Problem of Nuclear Fuel Element Components Using the Mortar Method and the Domain Decomposition Method
Authors: Aronov P.S. , Galanin M.P. , Rodin A.S.
Published: July 2021

The paper presents algorithms for solving axisymmetric contact interaction problems for several thermoelastic bodies using unmatched meshes. We employed the finite element method to obtain numerical solutions to problems of thermal conductivity and the theory of elasticity. We took contact interaction into account by applying the mortar method and the method of domain decomposition. The mortar method requires solving an ill-conditioned system of linear algebraic equations with a zero block at the main diagonal. To solve it numerically, we used a modified method of successive over-relaxation (MSSOR), which makes it possible to reduce solving the system of equations for all contacting bodies to sequentially solving systems of equations for each body separately. We showcase our algorithm results by solving an example problem simulating thermomechanical processes in a nuclear fuel element. We analyse the features of the stress-strain state in the structure and compare the results obtained using the mortar method and the domain decomposition method. The computational domain in the problem considered consisted of 10 nuclear fuel pellets and a cladding section. The analysis results showed that the quantitative stress-strain state properties in a system of bodies obtained by the two methods are quite close to each other. This confirms the fact that these algorithms may be correctly applied to solving similar problems
Approximating Damped Vibrations of Large Space Structures
Authors: Stets A.A.
Published: July 2021

It is possible to use data recorded by onboard acceleration sensors to verify mathematical models of large modular space structures in terms of simulating dynamic processes. The paper investigates an approach to approximating damped oscillations caused by dynamic impacts during operation. Initially, we approximate the response of the structure by summing damped harmonics derived from analysing the frequency spectrum of the dynamic process; then we use the Levenberg --- Marquardt algorithm in the parameter space of the harmonic set to find the best match between the real dynamic process and its approximation. We propose a modification of the approach considered which involves employing single harmonics to perform successive approximations of the function of time to be fitted. We show that it is possible to apply the approach proposed to identifying the frequency and dissipative parameters of the structure under consideration. The paper presents the results of testing the approach proposed via artificially generated noisy acceleration functions of time with known parameters, which were reconstructed with a sufficient degree of accuracy. A real-world example provided comprises the results of analysing the ISS accelerometer readings recorded against the background of damped vibrations in its structure that were caused by burns of its attitude control engines

Authors: Ohja P N , Singh Abhishek , Singh Brijesh
Published: July 2021

The constant decrease in the availability of good quality natural sand across the globe has led to increasing investigations on the possibility of utilizing by-products obtained from different industries as a replacement for natural sand. Copper slag and blast furnace slag are by-products of metallurgical processes occurring during copper and pig iron production, respectively. The substitution of natural sand using copper slag and blast furnace slag in plain and reinforced concrete has been permitted in Indian Standard IS: 383-2016 up to a certain percentage as replacing natural sand in concrete. In the present study, investigations were carried out to check the feasibility of increasing copper slag and blast furnace slag as a substitution of natural sand in concrete. Conventional (Natural) sand was replaced (by volume) with copper slag (0%, 25%, 50% & 75%), Granulated Blast Furnace Slag (GBFS) (0%, 30%, 60% & 100%) and Air-Cooled Blast Furnace Slag (ACBFS) (0%, 30%, 60% & 100%). Concrete mixes were examined by substituting conventional sand with copper and blast furnace slag in different proportions and were evaluated for different mechanical properties and durabil-ity-related parameters. Leaching studies were also carried out on selected concrete samples.
Ritual Domestikasi Padi Lokal dalam Budaya Sasak-Lombok
Authors: Saharudin Saharudin
Published: July 2021

The rice plant for Indonesia, especially in Lombok, is considered unique, not only as a production crop but also as a sacred plant. From the process of planting to harvesting, this plant is treated specially with rituals with religious nuances. This study aims to describe the socio-cultural symptoms of local rice domestication rituals among traditional farmers in Lombok. Based on this description, it is hoped that the views, knowledge, values, and rules will become the reference for the behavior of the rural Sasak people as growers of local rice types. The approach used to achieve this goal is a phenomenological approach. Primary data of this study were obtained through in-depth interviews (structured and non-structured to informants) and participatory observation. The results showed that the local rice domestication ritual is a form of awareness of the cultural-religious views of the local community by combining local knowledge and religious knowledge (Sufistic teachings, as represented in the mantra of planting rice and the concept of pare anak iwoq or orphan rice in pare pemol  or rice starter/marker) as a manifestation of the awareness of the Supreme Being and the cosmos. This awareness of the Supreme Being and the universe becomes a reference for local farmers in their behavior, especially in agriculture. With these two types of consciousness, they are guided and directed toward safety, security, and balance.

Political Economy of the Oil Palm Value Chain in Ghana
Authors: Asante Kofi Takyi
Published: July 2021

Oil palm (Elaeis guineensis) is of strategic importance to the Ghanaian economy. It is the second most important industrial crop after cocoa and is used widely in local food preparation as well as in industrial processing. In spite of its importance, however, oil palm has consistently underperformed since the early twentieth century. This paper conducts a value chain analysis of the crop, foregrounding the political economy factors that shape the performance of the sector. It draws on a combination of in-depth interviews conducted in March 2020 with a variety of value chain actors and a review of the secondary literature. Additionally, between late May and early June 2020, twelve further interviews were conducted as part of a rapid market survey to assess the impact of the COVID-19 pandemic on the value chain.
The Covid-19 Pandemic and Household Rice Consumption Patterns in Ethiopia: The Case of Addis Ababa
Authors: Alemu Dawit , Abate Gashaw T.
Published: July 2021

The outbreak of COVID-19 also resulted in moderate changes to the operation of the domestic rice value chain in Ethiopia. These were caused by changing responses of value chain actors (domestic and others engaged in rice imports) to the COVID-19 prevention measures put in place by the government. These changes increased the price of rice, which favoured rice producers and adversely affected urban consumers. This research note assesses household rice consumption patterns in Addis Ababa by comparing the situation before and during the COVID-19 pandemic, using a representative sample of households.
Freedom of Religious Belief and People with Disabilities: Evidence from India
Authors: Thompson Stephen , Rohwerder Brigitte , Arockiasamy Clement
Published: July 2021

Around the world, people with disabilities can be the most marginalised in society. Having a disability and being a member of a religious minority or an excluded social group can compound the reasons why some people find themselves on the outskirts of social systems which normally provide financial and moral support and a sense of identity and belonging. A recent study from India found that identity markers such as religion, caste and gender can exacerbate the exclusion already experienced by people with disabilities. Taking deliberate steps to strengthen the social inclusion of people with disabilities who also come from minority religious groups and socioeconomically marginalised backgrounds can help them fulfil their potential to fully and effectively participle in society on an equal basis with others, and strengthen community ties, making the society in which they live more inclusive.
Role of Faith and Belief in Environmental Engagement and Action in MENA Region
Authors: Avis William
Published: July 2021

This helpdesk report provides a critical review of the literature on the role of faith and religious values in environmental engagement and action. Contemporary studies have examined the relationship between religion and climate change including the ongoing “greening” process of religions. The review focuses on the responses of the Islamic faith in the MENA region to climate-related issues. MENA is considered one of the region’s most vulnerable to the impacts of climate change. The rapid review drawing from empirical findings notes that religious organizations have great potential in the protection of the environment. Religious organizations possess resources and infrastructure to positively impact the conversation on climate change. While the review acknowledges the important role that religion plays in environmental engagement, there is still no unified perception of climate change among members of the Islamic faith. There are those who believe that there are other more urgent issues such as radicalism, terrorism, democracy, and human rights. The review notes that the shared challenge of climate change can provide a mechanism to bring together faiths to discuss, share teachings, and agree on common action.

Social and Professional Adaptation: From Conceptualization To Measurement
Authors: Pinchuk Antonina
Published: July 2021

The article deals with the need to analyze social and professional adaptation under digital transformation in the labour market and the renewal of various professional activities resulted in developing new technology. The first part of the article considers the conceptual approaches to understanding the features of social and professional adaptation as an independent phenomenon, which have required the integration of conceptual developments in various branches of socio-humanitarian knowledge: sociology of adaptation, sociology of professions and social psychology. Based on the conceptual ideas presented, there defined social and professional adaptation, which is the inclusion of an actor in his profession through the formation of professional identity within the development of a professional role. This definition contains references to reconciling the internal needs of an actor in his professional self-realization and requiring the professional environment, which enunciates the interaction among the parties of adaptive relations in their professional sphere. Taking into account the adaptation situation, the features of social and professional adaptation are locally and globally analyzed and a clarification is made in the interpretation of «labour adaptation», which is similar in its content. The second part of the work enunciates the subjective and objective indicators of social and professional adaptation in the context of structural operationalization, which allows us to empirically study this phenomenon. The subjective indicators of social and professional adaptation are distinguished on the basis of an interpretive approach, according to which the effectiveness of adaptation should be studied through the self-assessment of an adaptor’s satisfaction with various aspects of his professional self-realization. The objective criteria of social and professional adaptation indentify the behavioural performance of an adaptation actor, which can acquire active and passive forms. The article introduces the general characteristics of methodological approaches to the analysis of social and professional adaptation in quantitative and qualitative research. The results are planned to be used in the future for a sociological study based on the developed conceptual and methodological framework.

DOES RELIGIOSITY AFFECT THE INTENTION TO PURCHASE HALAL FAST FOOD FROM NON-MUSLIM COUNTRIES OF ORIGIN?
Authors: Gunawan Arie Indra , Gaffar Vanessa
Published: July 2021

This paper aims to increase knowledge about the buying intention of halal fast food products. This study examines the influence of the country of origin of halal fast-food providers on purchase intentions. This study also measures the role of religiosity in mediating the relationship between country of origin and purchase intention of halal fast food. This knowledge will be very meaningful because the condition of Indonesia is the largest halal ecosystem, but in the fast-food category, it is dominated by providers from non-Muslim foreign countries. This research is a descriptive study, questionnaires were distributed randomly online via social media, finally getting 245 data from millennial Muslim consumers who could become research respondents. SEM-PLS with the help of statistical software WarpPLS 7.0 is used to explain the research model. This study shows that country of origin affects the purchase intention of halal fast food products, besides this research shows that religiosity is able to moderate country of origin towards the purchase intention of halal fast food. The results of this study reinforce the assumption that country of origin has a significant effect on purchase intention. Especially in fast food products, millennial consumers in Indonesia show that they already have a point of view and perception about the country of origin of halal fast food in Indonesia. Another finding in the study is that religiosity influences the purchase intention of halal fast-food, and has a moderating effect on the country of origin on purchase intention.

This result shows the investment behavior by investor where the inflation rate becomes a consideration whether to put their fund in investment, especially sharia mutual fund or more concern on their consumption. On the other side, the value of BI7DRR and the Jakarta Composite Index does not become investor’s consideration to investing in sharia mutual fund. For simultaneous effect, inflation, BI7DRR, and Jakarta Composite Index have a significant effect on the net asset value of sharia mutual fund for 66%, which shows that the combined economic situation consisting of these factors can affect the movement of the net asset value of sharia mutual fund with a possibility of 66%, while 34% of the possibility left can be affected by variables outside this research.
Megaleques das bacias sedimentares do Chaco e Pantanal: uma revisão comparada
Authors: Kuerten Sidney , Stevaux José Cândido
Published: July 2021

NaAmérica do Sul são encontrados os maiores sistemas fluviais distributáriosespalhados pelo planeta e correspondem às bacias sedimentares do Chaco e Pantanal. Este estudo apresenta uma revisão comparada dos morfométricos e hidrossedimentares desses megaleques publicados desde 1977. Esta revisão inclui dados paleoambientais, paleoclimáticos, estratigráficos e geomofológicos. Dentre as semelhanças e disparidades reconhecidas, as avulsões fluviais são responsáveis pelas maiores e constantes alterações nas superfícies quaternárias. Estes sistemas são grandes produtores de sedimentos, mas destaca-se o fato de que a maior quantidade permanece retida em ambas as bacias sedimentares, cujos valores atingem 68% no Chaco e 91% no Pantanal. Os megaleques analisados abrangem imensas áreas remotas e de difícil acesso o que pode ser constatado pela relativamente baixa produção científica. Por outro lado, as recentes mudanças ambientais e rápidas alterações de uso e ocupação podem gerar alterações desconhecidas dos processos naturais. Os limites teóricos dos megaleques foram revistos e ajustados com base nas características morfológicas observadas no modelo digital de elevação em comparação com os trabalhos produzidos.

Esse trabalho teve como objetivo apresentar um modelo evolutivo para encosta em unidade de relevo de baixa ordem na Superfície de cimeira de Pinhão/Guarapuava, com base na reconstrução morfoestratigráfica e pedossedimentar das formações superficiais. Para tanto, foi descrito seção estratigráfica que, em conjunto com análises laboratoriais, permitiramestabelecer os processos morfogenéticos e evolutivos ao longo do Quaternário Superior. Os resultados indicam sequência estratigráfica constituída por paleossolo enterrado na base, sobreposto por três sequências coluviais e uma sequência colúvio-aluvial. As descrições pedoestratigráficas dos níveis sedimentares indicaram a presença de nove horizontes pedoestratigráficos, cuja gênese e evolução é função da dinâmica entre pedogênese e morfogênese ocorrida no final do Pleistoceno e ao longo do Holoceno. Os dados obtidos pela descrição micromorfológica sugerema atuação de escoamento superficial e fluxos gravitacionais no retrabalhamento dos materiais ao longo da encosta. Tais fenômenos foram correlacionados aos resultados encontrados para a Superfície de Palmas/Caçador, setor guia de sinais paleoambientais regionais das superfícies de cimeira do Planalto Vulcânico na região sul. As idades obtidas por meio de 14C e LOE sugerem que a morfogênese atuou desde o final do Último Máximo Glacial até o Holoceno, materializados sob depósitos de colúvio e colúvio-alúvio. No Holoceno Médio registra-se incisão erosiva linear (voçorocas), cuja colmatação ocorreu ao longo do Holoceno Superior (MIS 1). A pedogênese progressiva atuou principalmente no Último Máximo Glacial, e entre os episódios de sedimentação das unidades coluviais. Em conjunto, a atuação da morfogênese e pedogênese regressiva provocaram parcial inversão do relevo, decorrente da erosão dos materiais da alta/média encosta e sedimentação na média/baixa encosta.

Is the Grass Greener in a Post-Pandemic World? (Re)Connecting Humanity with Nature for a Just Recovery
Authors: Blitzer Hannah
Published: July 2021

This article assesses the potential for reconnecting human and non- human nature in global post-COVID-19 recovery plans. The article utilises a critical perspective on the neoliberalisation of nature as a framing, as well as the case of sustainability and deforestation in forest risk commodity supply chains, to assess whether sustainable development initiatives and neoliberal environmental governance adequately protect the interests of vulnerable human and non- human nature. It finds that existing approaches to sustainable development in international governance prioritise liberalised global markets and the neoliberalisation of nature through commodification, privatisation and marketisation, thus furthering an unjust human-nature dichotomy by placing humans separate from nature and removing the intrinsic value of non-human materiality. It identifies a synergy between the global campaign to ‘build back better’ after COVID-19, environmental regulation and principles of Wild Law. The article concludes by recommending that a just post- pandemic economic recovery must realign the human experience as a part of the wider whole of the non-human natural world.

The devastating COVID-19 pandemic forced academia to go virtual. Educational institutions around the world have stressed online learning programs in the aftermath of the pandemic. However, because of insufficient access to ICT, a substantial number of students failed to harness the opportunity of online learning. This study explores the latent digital divide exhibited during the COVID-19 pandemic while online learning activities are emphasized among Bangladeshi students. It also investigates the digital divide exposure and the significant underlying drivers of the divide. A cross-sectional survey was employed to collect quantitative data mixed with open-ended questions to collect qualitative information from the student community. The findings revealed that despite the majority of students have physical access to ICT but only 32.5% of students could attend online classes seamlessly, 34.1% of the students reported the data prices as the critical barrier, and 39.8% of students identified the poor network infrastructure is the significant barrier for them to participate in online learning activities. Although most students possess physical access to the device and the Internet, they face the first-level digital divide due to the quality of access and maintaining subscriptions. Consequently, they fail to take advantage of physical access, resulting in the third-level digital divide (Utility Gap) and submerging them into a digital divide cycle. This paper aimed to explore the underlying issues of the digital divide among Bangladeshi students to assist relevant stakeholders (e.g., the Bangladesh government, Educational Institutions, Researchers) in providing the necessary insights and theoretical understanding to arrange adequate support for students to undertake conducive online learning activities.

Published: July 2021

The aim of this work was to study age-related changes in the behaviour of adult Wistar rats using the open field (OF) and elevated plus maze (EPM) tests. Behavioural changes related to motor activity and anxiety were of particular interest. Results showed that as male and female rats progressed from 2 to 5 months of age there was a decrease in the level of motor and exploratory activities, and an increase in the level of anxiety. Age-related changes were dependent upon initial individual characteristics of behaviour. For example, animals that demonstrated high motor activity at 2 months become significantly less active by 5 months, and animals that showed a low level of anxiety at 2 months become more anxious by 5 months. Low-activity and high-anxiety rats did not show any significant age-related changes in OF and EPM tests from 2 to 5 months of age, except for a decrease in the number of rearings in EPM. Significant individual differences in the behaviour of rats in OF and EPM tests observed at 2 months were not apparent by 5 months.
