Published: September 2023

Circularly polarized light (CPL) finds diverse applications in fields such as quantum communications, quantum computing, circular dichroism (CD) spectroscopy, polarization imaging, and sensing. However, conventional techniques for detecting CPL face challenges related to equipment miniaturization, system integration, and high-speed operation. In this study, we propose a novel design that addresses these limitations by employing a quarter waveplate constructed from a diamond metasurface, in combination with a linear polarizer crafted from metallic aluminum. The diamond array, with specific dimensions (a = 84 nm, b = 52 nm), effectively transforms left-handed and right-handed circularly polarized light into two orthogonally linearly polarized beams who have a polarization degree of approximately 0.9. The aluminum linear polarizer then selectively permits the transmission of these transformed linearly polarized beams.Our proposed design showcases remarkable circular dichroism performance at a wavelength of 280 nm, concurrently maintaining high transmittance and achieving a substantial extinction ratio of 25. Notably, the design attains an ultraviolet wavelength transmission efficiency surpassing 80%. Moreover, our design incorporates a rotation mechanism that enables the differentiation of linearly polarized light and singly circularly polarized light. In essence, this innovative design introduces a fresh paradigm for ultraviolet circularly polarized light detection, offering invaluable insights and references for applications in polarization detection, imaging, biomedical diagnostics, and circular dichroic spectroscopy.

Published: September 2023

Latar belakang. Leukemia merupakan keganasan yang sering terjadi pada anak dan kemoterapi merupakan terapi kuratif penting pada pasien leukemia limfablastik akut. Penggunaan kemoterapi pada awal diagnosis dapat memicu terbentuknya radikal bebas yang mengganggu homeostasis sel. Malondialdehid merupakan produk sekunder dari peroksida lipid yang dihasilkan oleh reaksi radikal bebas lemak tak jenuh dalam membran sel dan dapat digunakan sebagai penanda stress oksidatif. Protokol kemoterapi sebelumnya tidak konsisten. Protokol kemoterapi di Indonesia saat ini menggunakan protokol LLA 2018 yang berbeda dari protokol sebelumnya. Tujuan. Penelitian ini bertujuan mengetahui perbedaan kadar malondialdehid sebelum dan sesudah kemoterapi fase induksi pada anak dengan limfoblastik leukemia akut.Metode. Penelitian ini merupakan penelitian kohort prospektif dengan subjek penelitian anak berusia >1 bulan hingga 18 tahun dengan LLA yang mendapat pengobatan di Rumah Sakit Umum Pusat Prof. dr. IGN Gde Ngoerah dari bulan Juli 2021 hingga September 2022. Uji Wilcoxon digunakan untuk menilai perbedaan kadar malondialdehid sebelum dan sesudah kemoterapi fase induksi. Tingkat signifikansi ditentukan dengan nilai p <0,05.Hasil. Terdapat 30 subjek dalam penelitian ini. Median kadar malondialdehid serum sebelum kemoterapi fase induksi adalah 77,63 (20,45-578,66) dan menurun menjadi 66,63 (22,6-357,3) setelah kemoterapi fase induksi, tetapi tidak signifikan secara statistik (p=0,60). Pada kelompok sesudah kemoterapi fase induksi, terdapat peningkatan status gizi baik pada 22 subjek (73,4%), sedangkan sebelum kemoterapi hanya terdapat 15 subjek (50%), tetapi tidak signifikan secara statistik (p=0,464).Kesimpulan. Kadar malondialdehid menurun setelah kemoterapi fase induksi, terutama pada pasien dengan status gizi baik, meskipun tidak bermakna secara statistik.

Do Remittances and Terrorism Impact Each Other?
Authors: Kratou Hajer , Yogo Thierry
Published: September 2023

Current studies do not conclusively tell us whether there is a causal relationship between remittances and terrorism. Yet, this question is important because the answer has clear implications for the way remittances are monitored and handled. Hence, with this paper, we move a step closer to a definitive answer by studying the impact of remittances on specific terrorist events in 180 countries over the period 1970–2020. We also look in reverse at whether acts of terrorism attract remittances. From event-study analysis and a panel vector autoregression model, Granger causality tests, and a Cholesky decomposition to isolate shocks, we find that we can neither reject the hypothesis that remittances do not Granger-cause terrorism nor reject that terrorism does not Granger-cause remittances. We also find that terrorism response to remittances shock is negative. These findings do not support previous studies that show remittances could be used to fund terrorist attacks. Further, the response of remittance to terrorism shock is null, excepting for Latin America which shows a statistical negative effect. Remittances in Latin America do not appear to respond to conflict. Some of our findings are new, others contradict a large stream of literature (i.e. remittances as a potential source of financing). The insights should be useful to policymakers to facilitate the flow of remittances that result in more disposable income of recipient families and possibly help households to cope with the financial loss of terrorist activity.
miR-564 and miR-718 expressions are downregulated in colorectal cancer tissues
Authors: Mihcioglu Deniz , Elihan Erkan , Aytekin Alper , Gurer Turkan
Published: September 2023

Objectives

MicroRNAs (miRNAs) are small RNAs that are involved in regulating gene expression and have an important role in biological pathways such as differentiation, migration, cell proliferation, and other cellular processes. Previous studies have shown that miR-564 and miR-718 are either downregulated or upregulated in various cancers. The purpose of this study was to examine the levels of expression of miR-564 and miR-718 in colorectal cancer (CRC) patients’ tumor and non-tumor tissues.

Methods

The study group consisted of tumor and non-tumor tissues obtained from a total of 80 CRC patients. The expression levels of miRNAs were determined using quantitative Real-Time Polymerase Chain Reaction (RT-qPCR). Additionally, using bioinformatics analysis, the transcription factors (TFs) that are associated with miR-564 and miR-718 were identified as well as the GO (Gene Ontology) and KEGG (Kyoto Encyclopedia of Genes and Genomes) enrichment pathway analysis of these miRNAs.

Results

According to the findings of RT-qPCR, both miR-564 and miR-718 expression levels were significantly downregulated in CRC (p<0.001). There was a statistically significant correlation between the expression levels of miR-564 and miR-718 (p=0.006). Both miR-564 and miR-718 regulated TFs including E2F1, HIFIA, BRD4, KDM2B, ESR1, MYC, PHF8, RUNX1, TCF12 and YY1. According to KEGG analysis, miR-564 and miR-718 were associated with Hippo and FoxO signaling pathways, respectively (p<0.05).

Conclusions

miR-564 and miR-718 may have function as tumor suppressors and may be biomarkers for the diagnosis of CRC.

Homologous recombination (HR) is a prominent DNA repair pathway maintaining genome integrity. Mutations in many HR genes lead to cancer predisposition. Paradoxically, the implication of the pivotal HR factor RAD51 on cancer development remains puzzling. Particularly, no RAD51 mouse models are available to address the role of RAD51 in aging and carcinogenesis in vivo. We engineered a mouse model with an inducible dominant‐negative form of RAD51 (SMRad51) that suppresses RAD51‐mediated HR without stimulating alternative mutagenic repair pathways. We found that in vivo expression of SMRad51 led to replicative stress, systemic inflammation, progenitor exhaustion, premature aging and reduced lifespan, but did not trigger tumorigenesis. Expressing SMRAD51 in a breast cancer predisposition mouse model (PyMT) decreased the number and the size of tumors, revealing an anti‐tumor activity of SMRAD51. We propose that these in vivo phenotypes result from chronic endogenous replication stress caused by HR decrease, which preferentially targets progenitors and tumor cells. Our work underlines the importance of RAD51 activity for progenitor cell homeostasis, preventing aging and more generally for the balance between cancer and aging.

The centrosome is a cytoplasmic organelle with roles in microtubule organization that has also been proposed to act as a hub for cellular signaling. Some centrosomal components are required for full activation of the DNA damage response. However, whether the centrosome regulates specific DNA repair pathways is not known. Here, we show that centrosome presence is required to fully activate recombination, specifically to completely license its initial step, the so‐called DNA end resection. Furthermore, we identify a centriolar structure, the subdistal appendages, and a specific factor, CEP170, as the critical centrosomal component involved in the regulation of recombination and resection. Cells lacking centrosomes or depleted for CEP170 are, consequently, hypersensitive to DNA damaging agents. Moreover, low levels of CEP170 in multiple cancer types correlate with an increase of the mutation burden associated with specific mutational signatures and a better prognosis, suggesting that changes in CEP170 can act as a mutation driver but could also be targeted to improve current oncological treatments.

Yogurt, a widely consumed dairy product that undergoes fermentation, has garnered considerable interest due to its perceived capacity to promote health and well-being. The objective of this paper is to provide a thorough examination of the scholarly literature pertaining to the correlation between the consumption of yogurt and longevity. This study investigates the nutritional composition of yogurt, the significance of probiotics, potential mechanisms affecting lifespan, and the implications of yogurt consumption on chronic diseases and gastrointestinal well-being. Based on the existing body of evidence, it can be inferred that the consumption of yogurt potentially plays a role in extending the duration of one’s life by virtue of its positive impact on overall health and well-being.
Orthodox church building of the beginning of the 20th century in the territory of the present-day Lithuania
Authors: Bertash Alexander
Published: September 2023

The publication is devoted to a previously unexplored topic - the late Orthodox church building on the territory of modern Lithuania. It is based on unpublished materials from the Lithuanian State Historical Archives, as well as the Russian State Military Historical Archive, Kaunas Regional State Archives and local periodicals. The article contains a significant number of new attributions, the vast majority of churches and the names of architects were introduced into scientific circulation for the first time. The biographies of the largest builders of Lithuanian churches in the early 20th century are given – Diocesan architects M.M. Prozorov and A.A.Shpakovsky, the names of other architects of the Vilna diocese are established. The mechanisms of financing the construction of churches, mainly state-owned, with the support of the Peasant Land Bank, the composition of parishioners - in rural areas - Orthodox peasant settlers, in cities - Russian officials, military men, merchants, are considered. The special importance of resettlement (on the lands confiscated from Catholics), military, and station churches is considered. The style of temple building within Lithuania corresponded to the general imperial one: the dominance of the Russian style (Thon, Moscow-Yaroslavl, neo-Russian) and the presence of the Byzantine style. The long-term use of the style of K.A. Thones, the lack of local funds for construction, the proximity of the prerequisites for the construction of churches and their style in Lithuania and Belarus, and the difference from the situation in the territory of modern Latvia (except Latgale) and Estonia.
ARIadne – An Explanation Model for Digital Artefacts
Authors: Winkelnkemper Felix , Höper Lukas , Schulte Carsten
Published: September 2023

When it comes to mastering the digital world, the education system is more and more facing the task of making students competent and self-determined agents when interacting with digital artefacts. This task often falls to computing education. In the traditional fields of computing education, a plethora of models, guidelines, and principles exist, which help scholars and teachers identify what the relevant aspects are and which of them one should cover in the classroom. When it comes to explaining the world of digital artefacts, however, there is hardly any such guiding model. The ARIadne model introduced in this paper provides a means of explanation and exploration of digital artefacts which help teachers and students to do a subject analysis of digital artefacts by scrutinizing them from several perspectives. Instead of artificially separating aspects which target the same phenomena within different areas of education (like computing, ICT or media education), the model integrates technological aspects of digital artefacts and the relevant societal discourses of their usage, their impacts and the reasons behind their development into a coherent explanation model.

The main task of a modern school is the physical development and strengthening of the health of schoolchildren. However, the results of many studies indicate that, due to the intensification of the educational process and limited motor activity, the level of physical fitness of middle school students is insufficient. Scientists advise to increase the level of physical fitness to use additional sectional classes in various sports, in particular football. Therefore, the purpose of our work is to study the impact of sectional football classes on the level of physical fitness of schoolchildren aged 11-12. Material and methods: 30 boys aged 11-12 took part in the study. All subjects attended the soccer section 6 days a week. Standard tests were used to assess the physical fitness of schoolchildren. Results: The study lasted 16 weeks. During the period of the study, boys aged 11-12 years increased the results of the following tests: running 15 m from a standing position (by 2.55%, p<0.05), running 30 m (by 5.56%, p<0.05 ) and 60 m (by 5.71%, p<0.05) from a high start, long jumps (by 3.82%, p<0.05) and up (by 2.61%, p<0, 05) from standing, as well as triple (by 2.54%, p<0.05) and 5-fold (by 3.07%, p<0.05) jumps. Conclusions: The results of our research indicate that sectional football classes contribute to increasing the level of physical fitness of schoolchildren aged 11-12.
DECOMPOSITION OF PHOSPHORUS-CONTAINING COMPOUNDS IN AQUEOUS AND POLYSACCHARIDE SOLUTIONS OF ORGANIC ACIDS

Published: September 2023

The purpose was to study the patterns of dissolution (solubilization) of phosphorus-containing minerals in aqueous and polysaccharide solutions of organic acids in order to model the mechanism of mineral destruction by soil bacteria synthesizing organic acids and exopolysaccharides. Methods. Model, laboratory-analytical, microbiological, statistical. Results. The destructive effect of organic acids on minerals is manifested both in aqueous and polysaccharide solutions. The introduction of bacterial polysaccharide into an aqueous solution of acids increases the decomposition of phosphorus-containing minerals by 1.34̶ 4.96 times. The influence of the chemical structure of acid molecules on the intensity of mineral decomposition is mainly manifested in the presence of bacterial polysaccharide, while in an aqueous solution the effectiveness of acid action depends on the nature of the mineral being destroyed. To the maximum degree, polysaccharide increases the destruction of minerals in a solution of citric acid: molten magnesium phosphate ̶ 2.55 times, thermophosphate ̶ 2.11 times, phosphate flour ̶ 4.96 times. Decomposition of phosphorus compounds in solutions of ascorbic and oxalic acids enhances bacterial polysaccharide to a lesser extent than in citric acid solution. Modeling the destruction of phosphorus-containing minerals under non-sterile conditions (soil conditions) made it possible to establish that organic acids under non-sterile conditions are subject to consumption by soil microbiota, especially ascorbic and citric acids, and to a lesser extent - succinic. Aqueous solutions of organic acids after 18 hours of incubation in non-sterile conditions lose their leaching activity by 1.06 ̶12.1 times. The introduction of a polysaccharide into aqueous solutions of acids makes it possible to avoid their rapid consumption by microorganisms, because of which the efficiency of mineral leaching under non-sterile conditions decreasшes by only 5–20% compared to sterile ones. Conclusions. The introduction of a bacterial polysaccharide into a solution of organic acids enables the latter to be transferred to a sorbed state, as a result of which their susceptibility to consumption by microorganisms is sharply reduced. Thus, polysaccharide-forming bacteria not only destroy minerals more intensively than microorganisms synthesizing only low-molecular-weight metabolites, but also synthesize a more stable and long-term functioning leaching complex in the soil.

The article examines the economic aspects of the efficiency of power systems for mine loads, which include peak pumped-storage hydroelectric power plants that use reservoirs of the mine underground water drainage. The compari-son of power supply options was carried out according to the net present value (NPV) criterion, which was determined by changing the water inflow through the hydro turbine and power consumption. As a result of numerical experiments, it has been established that the greatest economic effect can be achieved by implementing a pumped-storage hydroelec-tric power plant consisting of four hydroturbines, two of which will be used during the half-peak price hours, and at other times, when the peak price is used, all facilities will be used to.

Colombia is a major biodiversity hotspot, having one of the richest orchid floras in the world. The country spans over a million square kilometers of land, hosting a multitude of different ecosystems thanks to the complexity of its mountainous systems and influences from neighboring countries in Central and South America, as well as the Atlantic and Pacific coastlines. Prior studies found an estimated 3591–4270 species of orchids occurring in Colombia, making it the most species-rich plant family in the country. About 35% of those orchids are members of the Pleurothallidinae subtribe, the largest group in the family and also that with the highest rate of species discovery. Here we record 1862 species of pleurothallids for the country, a significant increase from the 1286–1529 range estimated just a few years ago. We expect Pleurothallidinae to represent close to half the Colombian orchid flora. Colombia hosts roughly one third of all currently known taxa in the subtribe, and close to 60% of these species are found nowhere else in the world. These are clear indicators that the country is a highly important center of pleurothallid diversity and a key target for their conservation. The most species rich genera in the country are Stelis (521 species), Lepanthes (377 species), Pleurothallis (248 species) and Masdevallia (171 species). Country-level distribution is given for each accepted species. The closest floristic affinity is found with Ecuador, with which Colombia shares over 76% of the non-endemic Pleurothallidinae species, followed in the distance by Venezuela and Peru with just above one quarter of the non-endemics being shared. Numerous new country records are presented in the catalogue, many of which are illustrated with color photographs. We provide a full list of homotypic synonyms for each accepted taxon, as well as an annotated list of excluded taxa and newly proposed synonyms. Heterotypic synonyms are not listed, unless they are based on Colombian material. Typification for each accepted species is presented, with lectotypes, neotypes and epitypes being selected whenever necessary and available, as well as information regarding published illustrations.

Aim: To evaluate the spectrum of inflammatory features in foot joints which may be detected on routinely performed ultrasound (US) and magnetic resonance imaging (MRI) in children newly diagnosed with juvenile idiopathic arthritis (JIA). Material and methods: Two groups of children hospitalized in a reference center for rheumatology, newly diagnosed with JIA and suspected of foot involvement in the course of JIA were included in this retrospective study. In the first group of 47 patients aged 1–18 years, the imaging was restricted to US. The second group of 22 patients aged 5–18 years underwent only non-contrast MRI of the foot. Results: The most frequent pathologies seen on US included effusion and synovial thickening in the first metatarsophalangeal joint (MTP1), followed by the tibiotalar joint. Synovial hyperemia on color Doppler US images was present most frequently in the Chopart and midtarsal joints (64%; 7/11 cases), followed by the tibiotalar joint (45%; 5/11), and MTP2–5 joint synovitis (40%; 4/10). Grade 3 hyperemia was present only in four cases; grades 1 and 2 were detected in the majority of cases. On MRI, bone marrow edema was the most frequent pathology, found mostly in the calcaneus (45%; 10/22 cases), while alterations of the forefoot were rare. No cases of bursitis, enthesitis, cysts, erosions or ankylosis were diagnosed in either of the analyzed groups. Conclusions: Routine US of the foot is recommended for early detection of its involvement in JIA in daily clinical practice. Although MRI can identify features of various JIA stages, it is particularly useful for the detection of bone marrow alterations.

Plantar intrinsic muscles play a pivotal role in posture control and gait dynamics. They help maintain the longitudinal and transverse arches of the foot, and they regulate the degree and velocity of arch deformation during walking or running. Consequently, pathologies affecting the plantar intrinsic muscles (for instance, acquired and inherited neuropathies) lead to foot deformity, gait disorders, and painful syndromes. Intrinsic muscle malfunctioning is also associated with multifactorial overuse or degenerative conditions such as pes planus, hallux valgus, and plantar fasciitis. As the clinical examination of each intrinsic muscle is challenging, ultrasound is gaining a growing interest as an imaging tool to investigate the trophism of these muscular structures and the pattern of their alterations, and potentially to follow up on the effects of dedicated rehabilitation protocols. The ten plantar intrinsic muscles can be dived into three groups (medial, central and lateral) and four layers. Here, we propose a regional and landmark-based approach to the complex sonoanatomy of the plantar intrinsic muscles in order to facilitate the correct identification of each muscle from the superficial to the deepest layer. We also summarize the pathological ultrasound findings that can be encountered when scanning the plantar muscles, pointing out the patterns of alterations specific to certain conditions, such as plantar nerves mononeuropathies.

Para tanto, a pesquisa se debruça sobre 344 posts de Instagram, 57.309 tuítes e 444 trechos de discursos das deputadas federais Gleisi Hoffmann (PT), Jandira Feghali (PCdoB), Bia Kicis (PL) e Carla Zambelli (PL) que datam de março e maio de 2019, 2020 e 2021. A partir da análise do discurso crítica e da análise léxica automatizada, os resultados apontam a baixa tematização de discussões sobre gênero no corpus e uma atuação discursiva próxima às pautas gerais de seus partidos, divididos entre oposição e base governista.
Mulheres na Amazônia: lutas em defesa de seus corpos-territórios
Authors: Miranda Cynthia Mara , Barroso Milena Fernandes
Published: September 2023

Resumo: O artigo busca refletir sobre a organização das mulheres na Amazônia em defesa de seus corpos-territórios. A análise parte do pressuposto de que a exploração da Amazônia segue o mesmo projeto colonizador dos corpos-territórios e que as lutas contra a expropriação da natureza que impacta nas mudanças climáticas são vivenciadas de forma particular pelas mulheres que emergem como a principal força da resistência na atualidade. A partir de pesquisa teórica com análise bibliográfica e de narrativas, refletimos sobre o conceito de corpo-território, dando enfoque na mobilização das mulheres indígenas e quilombolas durante a COP 27. O estudo apontou que esse debate, numa perspectiva feminista, em que se considere o protagonismo dessas lideranças, pode mudar a compreensão das questões ambientais e gerar conscientização sobre a defesa dos corpos-territórios.
Feminismo Negro e Interseccionalidade em Periódicos Brasileiros (1992-2020)
Authors: Rodrigues Cristiano , Freitas Viviane Gonçalves
Published: September 2023

Resumo: Buscamos analisar a evolução da produção acadêmica brasileira sobre feminismo negro e interseccionalidade, no período de 1992 a 2020, por meio de uma análise bibliométrica e com raspagem de dados de artigos publicados em revistas das áreas de ciências sociais e humanas (A1, A2 e B1). Destacamos o impacto dos fluxos internacionais em difundir e adensar agendas de pesquisa sobre mulheres negras a partir dos anos 2000 e a importância de dossiês temáticos sobre gênero e raça em periódicos qualificados como mecanismo indutor para a ampliação da produção científica sobre as temáticas. Há um aumento contínuo de textos sobre tais questões a partir dos anos 2010, sugerindo que maior acesso de estudantes negros ao ensino superior e ampliação do debate público sobre interseccionalidade fora da academia possam estar gerando uma retroalimentação quanto ao interesse e à relevância do tema.
Transnacionalismo, interseccionalidade e ativismo na política de saúde para mulheres
Authors: Carvalho Layla Pedreira
Published: September 2023

Resumo: Propomos, neste artigo, a análise do desenho da Rede Cegonha e da resposta à epidemia do vírus Zika, desde a perspectiva das políticas de saúde para as mulheres no Brasil. Construímos essa análise à luz de uma tríade de fatores que influenciam o desenho das políticas públicas: a mobilização de narrativas transnacionais; a interseccionalidade dos determinantes sociais de saúde e a mobilização da sociedade civil, em particular os movimentos de mulheres e feministas. Por meio de pesquisa em documentos produzidos por autoridades de saúde pública e de entrevistas com mulheres ativistas em saúde, reconstruímos a trajetória das políticas de saúde para as mulheres e discutimos que a dimensão transnacional presente nessas ações e programas ainda é pouco considerada pela literatura quando analisamos o ciclo dessas políticas, sobretudo no que tange às narrativas apresentadas por governos e sociedade civil.
Itineraries and forms of management in the awarding of commendations by São Paulo municipal councillors: an exercise in researching with
Authors: Campos Pedro , Hoyler Telma
Published: September 2023

Abstract This article examines the awarding of commendations in the São Paulo municipal legislature. Seen at the interface between politicians and society, the granting of commendations is a highly ritualized practice, reflecting its importance in the management of social prestige and in political disputes over official history. However, the practice is little ritualized internally to the extent that one of its key stages, the collection of signatures, is performed by bureaucrats. This practice represents an organizational enactment of the agreement, an informal set of rules of conduct and institutions that operates in the legislature, producing predictability amid the competition over resources. In this arrangement, bureaucrats play a leading role in producing the boundaries between the dimensions of cooperation and political dispute, contributing to maintenance of the agreement. Inspired by the para-site methodology of George Marcus, which aims to afford the ethnographer better access to spaces of power, the study highlights what we call a method of researching with.
Disputes on abortion and sexual diversity in the Chamber of Deputies in the early years of the Bolsonaro government: the art of marking differences
Authors: Luna Naara
Published: September 2023

Abstract The present article explores the disputes in the Brazilian Chamber of Deputies about abortion and sexual diversity during the first two years of the Bolsonaro government (2019-2020). Focusing on the controversial moral themes of abortion and sexual diversity, the article examines legislative dynamics by analyzing statements made by congresspeople in the Chamber of Deputies s and the legislative proposals they submitted. This article is based on qualitative research, observing the discursive dynamic of mutual accusations and inversion of arguments. Particularly noteworthy in this context was the heavy engagement of religious actors in the defense of conservative positions.
Government institutions and cultural models: learning about civil service in the recruitment of a bureaucratic elite
Authors: Maia Bóris
Published: September 2023

Abstract This article examines the learning process of candidates in public selection exams for tax auditors in Brazil. Articulating cognitive theories of culture with anthropological studies of the state and its institutions, the author proposes the concept of a cultural model of civil service to explicate the standardized values and behaviours related to the bureaucratic-administrative practice that these institutions seek to instil in their agents. The aim is to show how the recruitment of a bureaucratic elite involves the incorporation of social representations concerning the role of state officials and the governmental legitimacy exercised in performing their function as auditors, even before the effective entry of these candidates into government institutions. The data is taken from ethnographic research conducted between 2015 and 2017 in Rio de Janeiro state, Brazil, which included participant observation in the classes of two preparatory courses for public selection exams.
Un abordaje del estado en/desde sus fronteras nacionales: el caso del lado argentino de la Triple Frontera del Paraná
Authors: Garcia Hernan Ezequiel
Published: September 2023

Resumen El presente artículo resulta de las discusiones sobre la perpetuada idea de estado y el empleo del método etnográfico en el estudio sobre los agentes y las instituciones estatales. Para ello se tomaron en cuenta las prácticas estatales de control fronterizo que formaron parte del proceso de cierre de fronteras llevado a cabo por agentes e instituciones que se encuentran nucleados en el Centro de Frontera Iguazú, ubicado en el lado argentino de la región transfronteriza de la Triple Frontera del Paraná. El escrito tiene un posicionamiento teórico que hace uso de la noción del estado nación como abstracción discursiva, pero, por otro lado, teniendo en cuenta que se (con)forma y se materializa por agentes e instituciones articulados entre sí, que presentan sus propias particularidades a su interior. Esto genera una ruptura con las nociones estáticas que llegan a considerar al estado como una entelequia omnipresente y homogénea.
Conflicts surrounding the “natural antidote against COVID-19”: Brazil sanitation governance in action
Authors: Ramos Lara , Marini Marisol , Corazza Rosana
Published: September 2023

Abstract As the COVID-19 pandemic sprawled across every continent, ‘hand-washing’ became the official guideline to prevent contagion. In this scenario, governmental and non-governmental actors mobilised to promote the provision of water supply and customer services to the largest number of people. With the imposed isolation, virtual events became the centre of the political debate, bringing to light strategies and challenges to guarantee basic needs, debated within the scope of the federal legislative and executive branches and civil society. The purpose of this article is to explore the discourses produced and the interventions proposed between April and May 2020. In the light of social studies of science and technology and discussions regarding the enactment and production of the state, mapped through the actions of key actors, this ethnography enables us to outline the conflicts of sanitation governance in Brazil.
Entre la teoría y el barrio. Etnografía caminante, política gubernamental y matriz académica en un programa de urbanización integral del hábitat en el Nordeste Argentino
Authors: Ojeda Valeria
Published: September 2023

Resumen En este trabajo me interesa marcar cómo se intersectan las matrices académicas y de gestión, cuando se trata de coordinar el diseño y la implementación de una política gubernamental de urbanización integral del hábitat. A partir de una experiencia de trabajo que me comprometió en tanto gestora proveniente del ámbito académico, busco describir con la mayor densidad posible, la incidencia de categorías del campo científico en la producción y puesta en marcha de proyectos impulsados desde el programa. Estas nuevas dimensiones significaron la emergencia de tensiones en los abordajes tradicionales de la cuestión social en el Programa de Mejoramiento de Barrios (PRO.ME.BA), tanto a nivel de las y los trabajadores del programa, como de los mismos ciudadanos (antes “población destinataria”), en una provincia del nordeste argentino.
Ethnographic Encounters: Using Ethnography to Study Brazil’s Participatory Governance Institutions
Authors: Cornwall Andrea , Cordeiro Silvia , Delgado Nelson Giordano
Published: September 2023

Abstract This article explores the contributions that ethnography and ethnographers can make to understanding governance institutions. Told through the story of a collaborative research project on participatory health governance in the municipality of Cabo de Santo Agostinho in north-east Brazil, we explore how the principles of ethnographic research intersected with other principles: of collaborative enquiry, participatory research and a methodological ethics grounded in the reversal of the conventional relationship between researcher and researched. Picking up on some of the core defining features of ethnography as a methodology, we examine how these came to inform our understanding of the dynamics of politics, power, and participation. In doing so, we reflect on how it is the pliable and improvisational nature of ethnography in practice that contrasts most substantially with the conventional tools of the political scientist and that makes ethnographic encounters so rich and valuable for the study of political institutions.
Gobernanza, reciprocidad y dinámicas políticas en Brasil: la auditoría como campo etnográfico
Authors: Lazaro João Paulo Pereira , Gonçalves Alicia Ferreira , Martín Juan Carlos Gimeno , Andrade Maristela Oliveira de , Melo Victoria Puntriano Zuniga de
Published: September 2023

Resumen La propuesta de este artículo es profundizar en la rutina de las instituciones de gobernanza, teniendo como espacio investigativo la gestión contratada de unidades de salud pública en un estado federativo de Brasil; fueron problematizadas las acciones de los agentes públicos enredados en las dinámicas de poder, construidas y mantenidas por las élites gubernativas y políticas. La investigación de campo tuvo como perspectiva metodológica la observación participante, que duró trece meses y exigió una mirada hacia el enfoque normativo, que dota al cotidiano administrativo de reglas formales; y otra mirada hacia las conductas informales y/o paralelas que atraviesan la rutina gubernativa, imponiendo sus reglas. Esta doble mirada fue una condición necesaria para aprehender cómo funciona el poder gubernativo al interior del movimiento de sus élites. Los resultados del estudio muestran las tramas que conducen hacia la apropiación de lo público con fines privados. Los análisis conclusivos afirman que el patrimonialismo sigue presente en el modo de gobernar las instituciones y conducir la política en Brasil.
