Memory and experience with children and young people living with HIV/AIDS: an autoethnographic essay
Authors: Darmont Mariana de Queiroz Rocha , Moreira Martha Cristina Nunes
Published: March 2023

ABSTRACT We submitted a theoretical essay supporting the proposal of autoethnography as a method of dialogue with the anthropology of emotions. From the autoethnographic-based narrative practice, we highlight the importance of the bond and the place of one of the investigators in the lives of these youngsters. The autoethnographic accounts of the investigators are found at the base, emerging from a 20-year work experience with children and adolescents, now young adults living with HIV/AIDS. The memories, experiences, feelings, and messages recently received by WhatsApp underpin the exercise of reflexiveness. Autoethnography is, most of all, an ethical option based on ethnographic reflexiveness, which allows us to revisit care, relationships, and practice from a critical and reflexive perspective.
Freud e a hermenêutica de Darwin
Authors: Ferretti Marcelo Galletti
Published: March 2023

Este artigo pretende mostrar em que medida Darwin inaugurou uma hermenêutica e como ela pautou a posição epistemológica de Freud. Para tanto, busca-se afastar, antes de mais nada, certa concepção corrente, mesmo entre biólogos, segundo a qual o darwinismo se resumiria à ideia da seleção natural. Visto que boa parte dos leitores de psicanálise e psicopatologia desconhecem essa espécie de discussão, o artigo procura dar atenção especial a ela. Em seguida, busca-se mostrar como Freud insere sua contribuição à ciência na esteira da de Darwin. Ambos revelaram - cada um à sua maneira e com propósitos distintos - ser possível uma investigação materialista da psique amparada numa hermenêutica naturalista. Por fim, retoma-se a crítica feita pela filosofia da psicanálise às interpretações de Habermas e Ricoeur com o intuito de ressaltar, com a ajuda de aspectos enfatizados por Lacan, o quanto as posições teórica e clínica vinculadas a tais interpretações se distanciam das posições de Freud.

Published: March 2023

Resumo Desenvolver habilidades para coordenar grupos é requisito importante do trabalho desenvolvido por psicólogos, especialmente quando vinculados a instituições de saúde pública. Este estudo foi uma pesquisa-ação amparada no enfoque clínico-qualitativo e desenvolvida a partir do dispositivo dos grupos operativos. O objetivo geral foi compreender como psicólogos percebem o trabalho grupal que oferecem em suas práticas laborais, a partir de vivências em grupos operativos de aprendizagem. Participaram 10 psicólogos atuantes em uma Unidade Ambulatorial de Atendimento Psicossocial - equipamento secundário da Rede de Atenção Psicossocial - de um município do interior de Minas Gerais. A ordenação de dados ocorreu a partir de emergentes grupais surgidos durante três sessões, e foram analisados a partir do diálogo com a literatura sobre grupos, em especial grupos em cenários institucionais. O processo grupal vivido fomentou recursos profissionais para lidar com a grupalidade. Expressões sobre dificuldades profissionais enfrentadas na coordenação de intervenções grupais apareceram e foram discutidas. O dispositivo “grupo” foi pensado como ferramenta possível de ser empregada para facilitar transformações e fomentar potenciais encontros humanos. Estudos futuros poderão ser direcionados a novas formas de compreender o trabalho grupal desenvolvido por esses e outros psicólogos, de realidades distintas da retratada.

Published: March 2023

Resumo O presente artigo objetiva realizar uma revisão de escopo da literatura, com o intuito de compreender as experiências formais de participação social que tem sido desenvolvidas no contexto da Atenção Primária em Saúde (APS) no Brasil, desde a criação do Sistema Único de Saúde (SUS) até novembro de 2020. Foram realizadas pesquisas nas bases Lilacs, PubMed, PsycINFO e Sociological Abstracts, sendo achados 20 artigos abordando a participação social e a APS. Os resultados encontrados foram discutidos no que se refere ao perfil dos participantes e à competência para participar, ao processo de participar e à construção de ações participativas, além da centralidade da educação permanente como forma de fortalecer a participação social em saúde. A pesquisa revelou distintas experiências de participação social desenvolvidas nos territórios onde atua a APS, destacando-se as dificuldades enfrentadas no processo de implementação dos Conselhos Locais de Saúde (CLS). Sendo assim, discute-se que o fortalecimento da APS, principalmente do modelo Estratégia Saúde da Família (ESF), envolve, de modo dialético, a construção e qualificação dos espaços participativos, o que resultaria em uma estratégia central de defesa do SUS em um momento de recrudescimento das relações democráticas no país.
Partially grouted concrete masonry shear walls subject to in-plane shear load: a critical review
Authors: Zhu Jianyixian , Shrive Nigel
Published: March 2023

abstract: Although structures have been built from masonry for many years, little is still known about the behaviour of a wall subject to in-plane shear. This is particularly true of partially grouted concrete masonry. The factors that are known to affect the strength of this type of masonry are discussed with the varying results and interpretations highlighted. There is consensus that increasing axial stress increases the shear strength and reduces the ductility of the masonry. However, whether reinforcement (both horizontal and vertical) contributes to strength remains an issue of debate, as is the effect of aspect ratio. Most codes and standards do not differentiate fully grouted from partially grouted masonry, often over predicting the shear strength of the latter. Wall versus panel failure is not considered. Much work needs to be done to improve our understanding of this material subject to in-plane shear.

Published: March 2023

Abstract: Aim Man-made reservoirs lead to several changes in their downstream rivers that depend on the hydraulic characteristics of the reservoirs. However, their multiple uses can also provide facilities that influence the ecosystem services that they provide. This study addressed the potential ability of a Neotropical reservoir to trap chemical species aiming to assess the role of these ecosystems to mitigate pollution. Methods Retention capability modeling was examined for a small subtropical reservoir with high hydraulic retention time (> 100 days). The temporal ranges of 9 physical and chemical water variables over a five-year period were used to calculate the mass balance and to determine the retentive capability (alpha parameter) of the Itupararanga Reservoir (São Paulo State, Brazil). To explain the long-term mass balance of these variables, it was assumed that the reservoir is a completely mixed system with a step input. Results The highest values of parametrized alpha (high retention capability) occurred in wet months (up to 500 mm) for all variables. High reaction rate constants (k) and low hydraulic flushing suggested that sink processes prevail over the export ones, mainly for total phosphorus. The rainfall pattern showed minor importance for trapping elements. Conclusions In the Neotropics, hydraulic characteristics of the ecosystem (e.g., low area:volume ratio) are a tool for pollution management in man-made reservoirs.

Rapid technological changes have radically changed the expectations of employers from the current generation of engineering graduates, necessitating educators to focus on the development of core subject comprehension and required skills among the students in their engineering programs. Research has shown that project-based learning (PBL) is an effective pedagogy to address this dual requirement of core technical knowledge and skills to effectively utilize this knowledge to solve problems. PBL is a pedagogical approach wherein students work to address real- world problems and challenges through the application of knowledge acquired in the class, unlike the traditional classroom approach involving lectures, studying, and taking tests. The core of every PBL course involves effective cooperation, collaboration, and communication among students and between students and faculty. It is believed that this hands-on learning through problem- solving, combined with the development of soft skills, helps enhance learning outcomes and elevates learning to higher cognitive levels. An innovative course titled “Engineering Exploration”, taught and co-designed by a multidisciplinary faculty is offered at the authors’ institution. The course is a core component of the first-year undergraduate engineering curriculum. During this course, students learn about and apply the full range of engineering design tasks, from the development of need statements and problem definition to virtual and physical prototyping, to solve real-world problems. A continuing outcome of this course is interdisciplinary problem-solving, engineering design process, and teamwork. Effective assessment of student learning is a challenge in PBL courses. To address this constant challenge, the authors have developed a comprehensive assessment strategy, incorporating summative, formative, and diagnostic assessments, to assess student learning throughout the course. This paper presents a discussion of these strategies, our experiences and observations, and strategies to incorporate the same into PBL courses.

Published: March 2023

The Institute for Policy & Social Research (IPSR) at the University of Kansas received funding from the Economic Development Administration at the U.S. Department of Commerce under the CARES Act to study broadband access in the state of Kansas. To conduct this study, IPSR examined existing data, fielded our own survey of broadband speeds and access, conducted focus groups, and commissioned a chapter on the digital divide within the state of Kansas. The report discusses available data sources and introduces the speed test data collected by IPSR in order to map the broadband access landscape in Kansas. Along with speed tests, the Kansas broadband survey collected information regarding broadband access, adequacy, affordability and satisfaction. The survey data were enhanced by interviews and focus groups that allowed Kansans to share their struggles with internet access in their own words. The report also investigates digital equity using surveys and interviews conducted at public libraries that revealed the challenges faced by library patrons, including lack of digital access and literacy. The report that is summarized below indicates a rural-urban digital divide in terms of access, affordability, and satisfaction with broadband services. The data in this report indicate that up to 1,000,000 Kansans live in regions that lack access to highspeed broadband services, now considered to be 100 megabits per second (Mbps) download and 20 Mbps upload (100/20). Close to half of survey respondents (46%) report dissatisfaction with broadband services.

Introduction. Additive technologies make it possible to curb material expenses by reducing allowances for the final dimensional machining of workpieces. For such expensive materials as copper and copper alloys, this method is considerably attractive from a perspective of increasing resource efficiency in production. The operational properties of the C65500 alloy manufactured using additive technologies have not been fully studied and require additional research. The aim of the work is to study the structural and phase state, mechanical and operational properties of C65500 bronze specimens printed using electron beam additive manufacturing technology. In the work, specimens made of C65500 wire with different heat input values are studied, some of which were subjected to thermal treatment and mechanical processing, as well as specimens, manufactured using multi-wire technology. The work uses such research methods as the study of corrosion resistance of bronze specimens using a potentiostat, confocal laser scanning microscopy, friction tests and X-ray phase analysis. Results and discussion. Processing of specimens by plastic deformation (compression) and subsequent annealing leads to the most serious structural changes. Based on X-ray phase analysis, it is found that higher silicon content is observed in the case of the addition of silumins to bronze. The study of mechanical properties shows that the specimens, printed using multi-wire technology, have the highest strength properties. During tribological testing, fluctuations in the value of the friction coefficient are revealed, due to the scheme of the experiment and the combined adhesive-oxidative mechanism of specimens’ wear. The addition of 10 wt.% aluminum filament to bronze in the additive manufacturing process is an effective means for increasing the resistance of the material to electrochemical corrosion and increasing its wear resistance.

Authors: Tumati Raja , Yousfi Moayad Dawood Al
Published: March 2023

Purpose- The study's aim is to determine the intrinsic rewards that Omani hotels use to inspire their employees and to analyse the extrinsic rewards that Omani hotels use to motivate their employees. The study also intends to investigate the association between incentive types and job satisfaction among hotel employees in Oman.
Methodology- The study employed a descriptive research design. The study's population was comprised of employees from five different four-star hotels in Oman. A systematic questionnaire was created and distributed to all participants. Rewards (both intrinsic and extrinsic) served as the study's independent variable, and job satisfaction served as the study's dependent variable. The data was gathered on a five-point scale and interpreted using averages, percentages, and correction analyses.
Findings- The study noticed that the intrinsic rewards employed by hotels in Oman included recognition and appreciation, an excellent working partnership with the manager, management trust and belief, training and professional development, and work freedom and autonomy. On the other hand, extrinsic rewards are used by hotels in Oman, such as praise and appreciation for a job well done, excellent working environments, attractive salaries, annual bonuses, and insurance for me and my family. Spearman's coefficient of 0.885 indicated a positive and significant relationship between intrinsic rewards and work satisfaction among Oman hotel employees. Similarly, a Spearman's coefficient of 0.899 demonstrated a very strong positive and significant association between extrinsic rewards and work satisfaction among Oman hotel employees.
Conclusion- The findings suggest that the level of employee job satisfaction in the organisation is reliant on rewards.

How do socially responsible investment and macroeconomic indicators interact with each other The case of selected developing countries
Authors: Tuncay Merve , Dorjnaran Bayarmaa
Published: March 2023

Purpose- Sustainability is a multidimensional concept that expresses not only sensitivity to environmental policies, biodiversity and climate change, but also corporate governance principles and human rights. Accordingly, socially responsible investment is a kind of investment considering not only financial criteria but also environmental, social and corporate governance factors as well. In today's world, both the increase in social chaos, disasters and epidemics all over the world reveal the importance of addressing the issue of sustainability at the institutional and even governmental level and taking urgent action.
In this context, sustainability indices have been created in many international stock markets since the end of the 1990s, which are created according to various criteria. These indices follow the companies that comply with the concept of sustainability. Today, many developing country stock markets also have sustainability indices.
In this study, the interaction between the change in the sustainability index and macroeconomic indicators in developing countries was examined in order to be able to set forth the significance of the impact level of sustainability on the economy in the developing countries.
Methodology- Within the scope of the subject, the importance of adapting to sustainability in the developing countries and the activities carried out are also discussed. Within the analysis, the annual percentage change in the sustainability index in seven selected developing countries and macroeconomic indicators such as change in consumer price index and change in dollar-based exchange rates were examined for the period of 2015-2022 by the panel data methodology.
Findings- According to the findings, the impacts of changes in exchange rates and consumer price index on the sustainability indices are statistically significant. While exchange rates have negative effect, consumer price indices have positive effect on the sustainability indices.
Conclusion- Findings are expected to reveal the supportability and importance of sustainability in the developing countries and shed light for future research that this issue needs and worth to be investigated more deeply.

Keywords: Sustainability, socially responsible investment, macroeconomic indicators, developing countries, panel data.

LEGAL REGULATION OF PAYMENT SERVICE IN UKRAINE
Authors:   aras Shevchenko National University of Kyiv, Lysenko Nadiia
Published: March 2023

The payment market of Ukraine has undergone significant changes in regulation in accordance with the Law of Ukraine "On Payment Services", which came into effect on August 1, 2022. As a result, instead of one payment service, the relevant law provides for ten payment services. Due to new types of services, the activities of payment service provider are going to vary and lead to different business models of activities. Consequently, there is a need to investigate the payment service in accordance with the Law of Ukraine "On Payment Services" as a separate object of legal regulation. The article examines the approaches to determining the nature of the term "service", and establishes which of the approaches is used in the payment service regulation. This article considers and systematizes payment services by different features. On the basis of features of the payment service, they could be categorized and can be identified as a separate object of legal regulation. These 10 new payment services are classified by the legislator according to different criteria, but at the same time they have one common feature: each payment service is directly or indirectly related to actions related to the transfer of money. Depending on the type of payment service, different requirements are applied to their provision in order to ensure the safety of the funds of clients of payment service providers. Payment service providers may also have different activity requirements that are proportionate to the risks inherent in a particular type of activity. With the help of a comparative analysis of scientific achievements and the legislation of Ukraine, as well as on the basis of isolated features of the payment service, it has been established whether it is possible to assert a separate regulation of the payment service. A definition of the term payment service is proposed, which can be used both in practical and academic areas.

Bu çalışmada helisel kanatlı borulu bir ısı değiştiricisinin Ansys-Fluent hesaplamalı akışkanlar dinamiği (HAD) paket programında sayısal çözümlemesi yapılmıştır. Sayısal çözümlemede akışkan giriş sıcaklığı ve boru dış yüzey sıcaklığı sabit tanımlanmış, akışkan olarak da dış ortam havası kullanılmıştır. Analizlerde kanat yüksekliği, boru çapı, kanat kalınlığı ve kanat adımı değiştirilerek 5000-20000 Re sayısı aralığında hesaplanan giriş hızlarıyla, elde edilen çıkış sıcaklıkları ve basınç düşümüne göre Nusselt sayısı ve sürtünme faktörü incelenmiştir. Değişken parametrelerden boru çapı ve kanat adımının artması ısı transfer etkisini artırırken, kanat yüksekliğinin ve kanat kalınlığının artması ise ısı transfer etkisinin azalttığı görülmüştür. Ayrıca, kanat kalınlığı ve kanat adımının artması sürtünme etkisini artırırken, boru çapı ve kanat yüksekliğinin artması ise sürtünme etkisinin azaldığı görülmüştür. Sayısal analizin doğrulaması literatürdeki deneysel sonuçlar ile karşılaştırılarak yapılmış ve sonuçlar arasında iyi bir uyum olduğu görülmüştür.

The 1995 Kobe, Japan, earthquake: A long-delayed aftershock of the offshore 1944 Tonankai and 1946 Nankaido earthquakes
Authors: Pollitz Fred F. , Selwyn Sacks I.
Published: March 2023

The 1995 Kobe earthquake produced predominantly right-lateral slip along the northeast-southwest-trending Nojima fault approximately 200 km landward of the Nankai trough, southwest Japan. The last major earthquakes along the Nankai trough, the M8.0 1944 Tonanakai and M8.2 1946 Nankaido earthquakes, involved about 4 m of interplate slip, each releasing about 100 years of accumulated stress from the northwest-southeast convergence of the Philippine Sea (PHS) plate. By calculating the change in Coulomb failure stress on the Nojima fault due to 1944/46 to 1995 postseismic relaxation of a thin low-viscosity channel beneath southwest Japan, we show that stress diffusion from the 1940s interplate earthquakes increased the likelihood of future failure on the Nojima fault by slowly but progressively unloading the normal stress on the fault over a 50-yr period.
Boundary shape waveform inversion for two-dimensional basin structure using three-component array data of plane incident wave with an arbitrary azimuth
Authors: Aoi Shin , Iwata Tomotaka , Fujiwara Hiroyuki , Irikura Kojiro
Published: March 2023

We extend a new waveform inversion scheme (Aoi et al., 1995) for estimating underground structure with an irregular-shaped basement as a target to cases where plane waves with an arbitrary azimuth impinge on the structure, i.e., from a direction not necessarily perpendicular to the major axis of the structure. We proved the validity of this scheme by numerical experiments. We had already achieved the formulation and numerical experiments for the cases where an SH wave impinges on a 2D basin structure and had shown that we could estimate the entire basin structure with seismic waveforms from only a few surface stations by using whole waveforms that include the surface waves. However, when the epicenter is located out of the plane including the observation stations, even the cases of 2D structure cannot be treated as a simple 2D (SH or P-SV) problem because of the wave with an azimuth that is not 0°. Therefore, by dealing with 3D wave fields in the present study, we extend the inversion scheme in order to apply it to incident waves with an arbitrary azimuth. The differential seismograms, which represent the sensitivity of change in the waveform, show different patterns in three components, and we demonstrate that inversion with three components, compared with the inversion with only one of them, leads to a linearized equation system with a smaller condition number and a more stable computation. Furthermore, we detect certain parts that are estimated with much less difficulty than others, depending on the direction from which the incident wave impinged. In the latter case, we can estimate the entire structure by employing simultaneously several data from incident waves arriving from different directions. We thus demonstrate by numerical experiments that the extension of our inversion method to cases where the incident wave with an arbitrary azimuth impinges on the structure enables us to estimate with increased accuracy an underground structure under more general conditions of the epicenter locations.
A free-surface boundary condition for including 3D topography in the finite-difference method
Authors: Ohminato Takao , Chouet Bernard A.
Published: March 2023

A flexible and simple way of introducing stress-free boundary conditions for including three-dimensional (3D) topography in the finite-difference method is presented. The 3D topography is discretized in a staircase by stacking unit material cells in a staggered-grid scheme. The shear stresses are distributed on the 12 edges of the unit material cell so that only shear stresses appear on the free surface and normal stresses always remain embedded within the solid region. This configuration makes it possible to implement stress-free boundary conditions at the free surface by setting the Lamé coefficients λ and μ to zero without generating any physically unjustified condition. Arbitrary 3D topographies are realized by changing the distribution of λ and μ in the computational domain. Our method uses a parsimonious staggered-grid scheme that requires only 3/4 of the memory used in the conventional staggered-grid scheme in which six stress components and three velocity components need to be stored. Numerical tests indicate that 25 grids per wavelength are required for stable calculation. The finite-difference results are compared with those of the boundary-element method for the two-dimensional (2D) semi-circular canyon model. We also present the responses of a segment of semi-circular canyon and hemispherical cavity to vertically incident plane P, SV, and SH waves and discuss the response of a Gaussian hill to an isotropic point source embedded in the hill. In the segment of semi-circular canyon, the later portions of the synthetics are characterized by phases scattered from the two vertical side walls. The hemispherical cavity and 2D semi-circular canyon both show focusing of energy at the bottom of the cavity, although the focusing effect is stronger in the former geometry. Focusing and defocusing effects due to the strong topography of the Gaussian hill produce a strong amplification of displacements at a spot located on the flank opposite to the source. Backscattering from the top of the hill is also clearly seen.
Italia di mezzo

The Italian debate concerning the relationship between cities and inner areas polarized around a few dichotomous - and somehow simplifying - positions. On the one hand exists the rhetoric addressing the ``villages'', intended as remote places to re-inhabit, escaping from the pandemic. On the other hand is the narrative of the metropolis, envisioned as a place-fulcrum from which to start again -- following the already-known patterns of growth and concentration -- despite the fragilities made explicit by Covid. In order to overcome these juxtaposed approaches, our work wants to shed light on the importance of ``intermediate territories'' intended as priority places to rethink within a new geography of marginality. In Italy, such intermediate territories, named \emph{Italia di mezzo}, occupy half of the national surface and host more than half of the population. Moreover, they embody extremely articulated geography: they include portions of twentieth-century urbanization (such as coastal settlements, industrial districts, various traits of ``città diffusa''), medium-sized cities with different administrative and functional centrality levels, sectors of metropolitan belts and a substantial share of rural areas in plains and hills. Faced with the radical risks and uncertainties that characterize the contemporary condition, it is essential to take care of these territories not only because they urgently need investments aimed at solving forgotten critical issues (from the necessary reconversion of production chains to the impact of climate change). These territories can also play a strategic positive role in the face of crisis phenomena thanks to their characteristics of elasticity and plasticity. If we look at them from a relational point of view - and not only from a topological one - these intermediate territories can play the role of two-sided ``intermediaries'' and ``hinges.'' On the one hand, they can be prepared to provide assistance and support to the inner and less densely populated areas; on the other hand, by taking advantage of their infrastructural and social capital, they can offer decongesting opportunities for most polluted metropolitan areas and more accessible living and working conditions.
The BRICS in the sustainable agenda: Performance analysis of ESG indices in the financial markets in Brazil, China, India and South Africa
Authors: Neto Joao Jose de Melo , Fontgalland Isabel Lausanne
Published: March 2023

The term ESG emerged in the report of the Global Compact (UN) in partnership with the World Bank, entitled Who Cares Wins: Connecting Financial Markets to a Changing World. However, the concept and measurement associated with ESG is not a fixed concept and there is no consensus on the exact list of issues and their materiality, but it is certain that it affects the value creation of a company. In 2006, a grouping was created, incorporating the foreign policy of Brazil, Russia, India and China, the bloc focuses on solving socioeconomic problems and using its competitive advantages, the BRICS has a proposal for sustainable development and consequently ESG. This study is justified by the fact that several empirical evidences show the benefits of the ESG agenda in the market, however, there is a gap when considering developing countries. In this article, a comparison was made between returns and performances through the average return, then the risk measurement measures are presented, namely variance, standard deviation, volatility and value at risk, in addition to the calculation of covariance, correlation, beta and drawdown, with data from the MSCI ESG Leaders index. We confirm the theory of long-term gains since in the period studied the average profitability of the ESG indices were higher in all countries compared to the broad index. As for volatility risk measures, our study confirmed the hypothesis that the risks of larger companies are greater than those of ESG companies.

The purpose of this work is to study the influence of four-magnon (4M) parametric instability on spin pumping by dipole-exchange magnetostatic surface waves (MSSW) with the help of the inverse spin Hall effect (ISHE) in structures based on yttrium-iron garnet (YIG) and platinum (Pt). Methods. The experiments were carried out using the delay line structures based on YIG(900 nm)/Pt(9 nm) where electromotive force (EMF) induced by ISHE demonstrates a growth at the frequencies of the resonant interaction between MSSW and volume exchange modes. The frequency dependencies of the amplitude and phase for the delay line structure and EMF (𝑈(𝑓)) from the platinum layer were studied as a function of the MSSW power. Results. It was shown that the resonant EMF growth at the frequencies of dipole-exchange resonances is caused by the presence of Van Hove singularities in the density of states for spin waves at such frequencies that leads to an increase in the efficiency of electron-magnon scattering at the YIG–Pt interface. A growth in MSSW power beyond the threshold of 4M instability development results in a “smoothing” of resonant particularities in the EMF frequency dependence 𝑈(𝑓) that can be explained by decreasing efficiency of spin pumping due to destruction of dipole-exchange resonances and related singularities in the density of states of spin waves. Conclusion. Obtained results may be of interest for the development of highly sensitive spin current detectors, as well as for the implementation of spintronic devices.
