Published: July 2023

ZnO is an effective photocatalyst applied to the degradation of organic dyes in aqueous media. In this study, the UV-light and sunlight-driven photocatalytic activities of ZnO nanoparticles are evaluated. A handheld Lovibond photometer was purposefully calibrated in order to monitor the dye removal in outdoor conditions. The effect of ZnO defect states, i.e., the presence of zinc and oxygen defects on the photocatalytic activity was probed for two types of dyes: fuchsin and methylene blue. Three morphologies of ZnO nanoparticles were deliberately selected, i.e., spherical, facetted and a mix of spherical and facetted, ascertained via transmission electron microscopy. Aqueous and non-aqueous sol-gel routes were applied to their synthesis in order to tailor their size, morphology and defect states. Raman spectroscopy demonstrated that the spherical nanoparticles contained a high amount of oxygen vacancies and zinc interstitials. Photoluminescence spectroscopy revealed that the facetted nanoparticles harbored zinc vacancies in addition to oxygen vacancies. A mechanism for dye degradation based on the possible surface defects in facetted nanoparticles is proposed in this work. The reusability of these nanoparticles for five cycles of dye degradation was also analyzed. More specifically, facetted ZnO nanoparticles tend to exhibit higher efficiencies and reusability than spherical nanoparticles.

Published: July 2023

Polylactic acid (PLA) is a biodegradable polymer made from natural sources, and its electrospinning (e-spinning) nanofiber membrane doped with antibacterial ingredients is widely used in the field of medical dressings. In this research, 9 wt% of rosmarinic acid (RosA) and 0.04 wt% of graphite oxide (GO) with synergistic antibacterial activity were introduced into the e-spinning PLA precursor solution, and the obtained PLA nanofiber membrane showed good antibacterial properties and wound healing effects. At the same time, a nonionic amphiphilic polymer, polyethylene glycol (PEG), was also introduced into this system to improve the hydrophilicity of the e-spinning membrane for wound healing application. The morphological characterization showed the RosA/GO and PEG did not affect the e-spinning of PLA. The tests of mechanical performance and wettability demonstrated that PEG and RosA/GO incorporated in PLA have migrated easily to the surface of the fiber. The e-spun PLA/PEG/RosA/GO membrane showed good antibacterial activity and promoted initial wound healing quickly, which would be a promising application in wound dressing.

Infection with Fasciola hepatica (liver fluke) causes fasciolosis (or fascioliasis) and poses a considerable economic as well as welfare burden to both the agricultural and animal health sectors. Here, we explore the ex vivo anthelmintic potential of synthetic derivatives of hederagenin, isolated in bulk from Hedera helix. Thirty-six compounds were initially screened against F. hepatica newly excysted juveniles (NEJs) of the Italian strain. Eleven of these compounds were active against NEJs and were selected for further study, using adult F. hepatica derived from a local abattoir (provenance unknown). From these eleven compounds, six demonstrated activity and were further assessed against immature liver flukes of the Italian strain. Subsequently, the most active compounds (n = 5) were further evaluated in ex vivo dose response experiments against adult Italian strain liver flukes. Overall, MC042 was identified as the most active molecule and the EC50 obtained from immature and adult liver fluke assays (at 24 h post co-culture) are estimated as 1.07 μM and 13.02 μM, respectively. When compared to the in vitro cytotoxicity of MDBK bovine cell line, MC042 demonstrated the highest anthelmintic selectivity (44.37 for immature and 3.64 for adult flukes). These data indicate that modified hederagenins display properties suitable for further investigations as candidate flukicides.
Curiosity and Democracy: A Neglected Connection
Authors: Papastephanou Marianna
Published: July 2023

Curiosity’s connection with democracy remains neglected and unexplored. Various disciplines have mostly treated curiosity as an epistemic trait of the individual. Beyond epistemology, curiosity is studied as a moral virtue or vice of the self. Beyond epistemic and moral frameworks, curiosity is examined politically and decolonially. However, all frameworks remain focused on the individual and rarely imply a relevance of curiosity to democracy. The present article departs from such explorative frameworks philosophically to expand the research scope on curiosity in the direction of democratic theory. It highlights the complex politics of curiosity as a collective, rather than merely individual, desire for knowledge. I argue that curiosity should become a key analytical category for studying democracy as a political attitude and as a way of life. Investigations of the multifaceted curiosity of the demos may enhance the visibility of ethico-political issues that often escape the curious eye of citizens and researchers.

Rice is one of the most important crops in the world and is considered a strategic crop for food security. Furthermore, the excessive use of chemical fertilizers to obtain high yields causes environmental problems. A sustainable alternative includes taking advantage of beneficial bacteria that promote plant growth. Here, we investigate the effect of five bacterial biofertilizers from halophytes on growth, and we investigate photosynthetic efficiency in rice plants grown under saline conditions (0 and 85 mmol L−1 NaCl) and future climate change scenarios, including increased CO2 concentrations and temperature (400/700 ppm and 25/+4 °C, respectively). Biofertilizers 1–4 increased growth by 9–64% in plants grown with and without salt in both CO2- temperature combinations, although there was no significant positive effect on the net photosynthetic rate of rice plants. In general, biofertilizer 1 was the most effective at 400 ppm CO2 and at 700 ppm CO2 +4 °C in the absence of salt. Inocula 1–5 also stimulated plant length at high CO2 levels without salt. Finally, the positive effect of biofertilization was attenuated in the plants grown under the interaction between salt and high CO2. This highlights the significance of studying biofertilization under stress interaction to establish the real potential of biofertilizers in the context of climate change conditions.
Comparative Cytogenetics and Fluorescent Chromosome Banding in Five Indian Species of Dipcadi Medik
Authors: Samanta Tundra , Jha Timir B. , Ray Sudipta , Jha Sumita
Published: July 2023

The genus Dipcadi Medik. (Subfamily: Scilloideae) has a narrow distribution in India and several overlapping morphological traits make the genus taxonomically challenging at the species level. Cytogenetic characterization can provide additional taxonomic data and can be used to evaluate genetic diversity at the species level. We have accomplished comparative karyotype analysis and fluorescence banding patterns using 4′-6-Diamidino-2-phenylindole (DAPI) and Chromomycin A3 (CMA) in five Indian species for the first time. The karyotypes of D. concanense and D. goaense exhibited similar fluorochrome banding profiles. However, D. montanum, D. ursulae and D. erythraeum differ distinctly in their karyotypes. In all taxa, CMA+ve/DAPI−ve or DAPI0 (GC-rich) constitutive heterochromatin was located at the constriction region or terminal satellite of the nucleolar chromosome. DAPI+ve/CMA−ve or CMA0 (AT-rich) heterochromatin dominates in D. montanum, D. ursulae and D. erythraeum. However, D. erythraeum shows a distinct variation in fluorochrome banding pattern from all other species. The distribution of CMA and DAPI bands is a reflection of heterochromatin composition and variations acquired by different species. This characterization can be used to assess phylogenetic relationships in the understudied genus Dipcadi and may serve as a basis for other genomic analyses and evolutionary studies.

Published: July 2023

Wearable electronic sensors have attracted considerable interest in hand motion monitoring because of their small size, flexibility, and biocompatibility. However, the range of motion and sensitivity of many sensors are inadequate for complex and precise finger motion capture. Here, organic and inorganic materials were incorporated to fabricate a hybrid electronic sensor and optimized and woven into fabric for hand motion detection. The sensor was made from flexible porous polydimethylsiloxane (PDMS) filled with multiwalled carbon nanotubes (MWCNTs). The weight ratios of MWCNTs and geometric characteristics were optimized to improve the hybrid electronic sensor, which showed a high elongation at the breaking point (i.e., more than 100%) and a good sensitivity of 1.44. The strain-related deformation of the PDMS/MWCNT composite network resulted in a variation in the sensor resistance; thus, the strain level that corresponds to different finger motions is be calculated. Finally, the fabricated and optimized electronic sensor in filiform structure with a 6% MWCNT ratio was integrated with smart fabric to create a finger sleeve for real-time motion capture. In conclusion, a novel hybrid E-fiber sensor based on PDMS and MWCNTs was successfully fabricated in the current study with an optimal M/P ratio and structure, and textile techniques were adopted as new packaging approaches for such soft electronic sensors to create smart fabric for wearable and precise detection with highly enhanced sensing performance. The successful results in the current study demonstrate the great potential of such hybrid soft sensors in smart wearable healthcare management, including motion detection.

Published: July 2023

Remaining Useful Life (RUL) prediction is an important component of failure prediction and health management (PHM). Current life prediction studies require large amounts of tagged training data assuming that the training data and the test data follow a similar distribution. However, the RUL-prediction data of the planetary gearbox, which works in different conditions, will lead to statistical differences in the data distribution. In addition, the RUL-prediction accuracy will be affected seriously. In this paper, a planetary transmission test system was built, and the domain adaptive model was used to Implement the transfer learning (TL) between the planetary transmission system in different working conditions. LSTM-DNN network was used in the data feature extraction and regression analysis. Finally, a domain-adaptive LSTM-DNN-based method for remaining useful life prediction of Planetary Transmission was proposed. The experimental results show that not only the impact of different operating conditions on statistical data was reduced effectively, but also the efficiency and accuracy of RUL prediction improved.
Reconstructing the Paleoenvironmental Evolution of Lake Kolon (Hungary) through Integrated Geochemical and Sedimentological Analyses of Quaternary Sediments
Authors: Vári Tamás Zsolt , Gulyás Sándor , Sümegi Pál
Published: July 2023

Lake Kolon (Hungary), situated in the middle of the Turjánvidék area between the saline lakes of the Danube valley and the Homokhátság, is one of the most significant natural aquatic habitats in the Danube–Tisza Interfluve region. The central question of this study is how the lake changed, and how environmental factors and human activities have influenced these paleoenvironmental changes in Lake Kolon. A multiproxy analysis of a core sequence (loss on ignition, grain size, magnetic susceptibility, and geochemistry) provided crucial insights. Notably, correlations are observed in the following relationships: (1) clay, organic matter, and elements derived from organic sources, such as Na, K, and Zn; (2) MS, sand, inorganic matter, and elements originating from inorganic sources, such as Fe, Al, Ti, Na, K, and P; and (3) carbonate content and elements originating from carbonate sources, such as Ca and Mg. The lake’s paleoenvironment underwent significant changes in the past 27,000 years. Late-Pleistocene wind-blown sand provided the bottom for an oligotrophic lake (17,700 BP), followed by a calcareous mesotrophic Chara-lake phase (13,800 BP). Peat accumulation, along with the eutrophic lake phase, began at the Pleistocene–Holocene boundary around 11,700 BP. From 10,300 BP, with the emergence of an extended peatland phase, the percentage of organic matter (peat) increased significantly. Anthropogenic changes occurred from around 9000–8000 BP due to the different emerging cultures in the Carpathian basin, and from 942–579 BP due to the Hungarian settlements and activity nearby, respectively.
A Transition Period Ritual of the Karay Turks: Death
Authors: Atmaca Emine , Gözdaş Reshide , Kaynak Iltar Ekin , Akçoru Rabia , Tağman Süleyman Ertan
Published: July 2023

Karaism is a Jewish sect that emerged in the Middle Ages and became the name of a Turkish tribe in time. Its name is derived from “kara- (K-R-A)”, meaning “the ones who can read the sacred scripture” in Aramaic–Hebrew. The Karaites are members of the Jewish Karai sect, which only accepts the Torah. This feature naturally causes many differences. One of the main differences observed is the rituals for an individual in the death transition period, an important phase of human life. In this study, the death-themed core beliefs of the Karaites, which are brought from the roots of the Turkish genealogical tree, and the rituals that are combined with Judaism are analyzed. The differences stemming from geography and contacts with diverse cultures (such as Russian, Lithuanian, Polish, Belarussian, etc.) and the similarities in the rituals at the time of death and afterward stand out, especially funerals, which comprise the mourning traditions performed during and after the funerals belonging to the Karaites living in Crimea and Lithuania. Texts and words compiled from the Karay Turks living in Trakai, Lithuania, and the data acquired via observations are used to determine this information. In particular, the studies of Yuriy Aleksandroviç Polkanov, the head of the Crimean Karaites Association, are used for the data related to Crimean Karaites.
Sad Cases and Success Stories: Representations of Multiple Sclerosis in Direct-to-Consumer Pharmaceutical Advertising
Authors: Houston Ella
Published: July 2023

This article examines representations of multiple sclerosis in direct-to-consumer pharmaceutical advertisements televised during 2021 in the United States. Drawing on and developing Cultural Disability Studies theory, it highlights how advertising produced by pharmaceutical companies influences mass understandings, as well as personal experiences of, multiple sclerosis. The application of textual analysis to a small-sample of direct-to-consumer advertisements that promote drug therapies for multiple sclerosis (n. 4) uncovers the prevalence of profit-driven, rather than person-driven, medical neoliberal ideologies. On first impressions, the advertisements appear to challenge the metanarrative of multiple sclerosis as a life-limiting tragedy. However, the research findings reveal that multiple sclerosis is framed as the “hidden enemy” of the American dream, supposedly threatening individuals’ abilities to live productive and meaningful lives, while the consumption of pharmaceutical “wonder” drugs is treated as an act of self-empowerment.

Authors: Rodrigues Cristina I. Dias , Brito Luís Miguel , Nunes Leonel J. R.
Published: July 2023

This review article aims to acknowledge the multifaceted functions of soil, and given its status as the largest terrestrial carbon store, to reaffirm its previously established importance in carbon sequestration. The article outlines the key variables that affect soil’s ability to trap carbon and highlights the significance of soil in halting climate change. A bibliometric study of seven sets of keywords relating to the significance of soil in carbon sequestration for climate change mitigation laid the foundation for this review. The literature review that followed, which was based on the bibliometric analysis, concentrated on carbon sequestration and the impact of the key factors that affect the amount of organic carbon in soil, including (1) climatic conditions; (2) topography; (3) parent material; (4) organisms; and (5) soil qualities. The goal of this review article is to recognize the diverse roles of soil, while reasserting its well-documented significance in carbon sequestration. This is particularly important considering soil’s position as the largest terrestrial storehouse of carbon.

Digital breast tomosynthesis (DBT) reconstructions introduce out-of-plane artifacts and false-tissue boundaries impacting the dense/adipose and breast outline (convex hull) segmentations. A virtual clinical trial method was proposed to segment both the breast tissues and the breast outline in DBT reconstructions. The DBT images of a representative population were simulated using three acquisition geometries: a left–right scan (conventional, I), a two-directional scan in the shape of a “T” (II), and an extra-wide range (XWR, III) left–right scan at a six-times higher dose than I. The nnU-Net was modified including two losses for segmentation: (1) tissues and (2) breast outline. The impact of loss (1) and the combination of loss (1) and (2) was evaluated using models trained with data simulating geometry I. The impact of the geometry was evaluated using the combined loss (1&2). The loss (1&2) improved the convex hull estimates, resolving 22.2% of the false classification of air voxels. Geometry II was superior to I and III, resolving 99.1% and 96.8% of the false classification of air voxels. Geometry III (Dice = (0.98, 0.94)) was superior to I (0.92, 0.78) and II (0.93, 0.74) for the tissue segmentation (adipose, dense, respectively). Thus, the loss (1&2) provided better segmentation, and geometries T and XWR improved the dense/adipose and breast outline segmentations relative to the conventional scan.

Published: July 2023

Background: To investigate the repeatability in vessel caliber measurements by optical coherence tomography angiography (OCTA). Methods: In this prospective study, 28 patients (47 eyes) underwent sequential OCTA imaging of the optic nerve head and macula. Two independent masked graders measured vessel caliber for sequential images of the optic nerve head and macula. The average vessel width was determined and variability between graders and images. Results: A total of 8400 measurements of 420 vessels from 84 OCTA images were included in the analysis. Overall, inter-grader agreement was excellent (ICC 0.90). The coefficient of variation (CoV) for all repeated OCTA images was 0.10. Greater glaucoma severity, older age, macular location, and diagnosis of diabetes were associated with thinner vessels (p < 0.05). CoV was higher in the peripapillary region (0.07) as compared to the macula (0.15). ICC was high for all subgroups except for the macula (ICC = 0.72). Conclusions: Overall, the repeatability of vessel caliber measurements by OCTA was high and variability low. There was greater variability in the measurement of macular vessels, possibly due to technical limitations in acquiring accurate vessel widths for smaller macular vessels.

Postoperative meningitis is quite rare in the practice of a spine surgeon and, as a rule, is associated with unintentional damage to the dura mater or necessary durotomy. According to a number of researchers, emergency interventions, severe spinal cord injury, prolonged preoperative stay in intensive care, diabetes mellitus, obesity, smoking, and age over 65 are risk factors for the development of postoperative meningitis in spinal injury surgery. The development of postoperative meningitis lengthens the time of hospitalization, requires prolonged antibacterial therapy, and significantly deteriorates the outcome of surgical treatment, which determines the relevance and significance of studying this issue. The article presents our own experience of 12 cases of patients with meningitis after spinal injury surgery, which accounted for 0.6 % of all interventions.

The article is devoted to evaluating the effectiveness of transcranial magnetic stimulation in the complex therapy of treatment-resistant depressions complicated by residual organic insufficiency of the central nervous system. For this purpose, a sample of 109 patients with this pathology was randomly divided into a main group (55 people) and a control group (54 people). The patients of the main group received a combination of antidepressants and 12 sessions of transcranial magnetic stimulation according to the iTBS protocol. The patients of the control group received only psychopharmacotherapy with a combination of antidepressants. The patients of both groups were examined at 2 and 4 weeks from the start of treatment, as well as in the catamnesis after 1 month and 6 months after the end of treatment, using BDI, BAI, CGI-S, and CGI–I questionnaires. It has been proved that the complex therapy of treatment-resistant depressions complicated by residual organic insufficiency of the central nervous system with the use of TMS sessions and psychopharmacotherapy is more effective than with isolated psychopharmacotherapy, which was confirmed by a statistically significant more pronounced reduction in the severity of depression and anxiety according to psychometric questionnaires and an improvement of the clinical condition on the CGI–I scale.

The article analyzes the existing approaches to the implementation of personalized application of corrective actions. In relation to the factors of combined physiotherapy, the information value of the search and selection of predictor biomarkers from among the parameters reflecting the initial hormonal, metabolic, and hemodynamic characteristics of patients is considered. It has been found that a cluster of variables, including body mass index, catalase activity, vegetative balance index, and tissue microcirculation index, has a predictive information value in relation to the combined use of transcranial magnetic therapy and a pulsed low-frequency electrostatic field. The performed verification of the obtained information model of multiple regression convincingly proves its adequacy and objectively confirms compliance with the specified requirements.

Authors: Mula Ayat , Abdulwahid Mohammed
Published: July 2023

This study investigated the performance of symmetric airfoils of type NACA0012 numerically under different operating conditions. It has been assumed that the study involves steady state, non-compressive, and turbulent flows. The operating fluid was air. The effect of Reynolds number and angle of attack on lift and drag coefficients, pressure distribution, and velocity distribution was investigated. ANSYS FLUENT has been used to solve the numerical model by using continuity equations, Navier-Stokes equations, and the appropriate K-ω SST perturbation model. This study shows a clear difference between the pressure coefficient of the lower and upper surfaces of the airfoil at high Reynolds numbers, indicating higher lift at high Reynolds numbers. As the maximum stall angle of the airfoil NACA0012 is 14° after which it decreases significantly, a direct relationship was observed between lift and drag coefficients and angle of attack.

The shear panels of plate girder made from corrugated in the web is investigated in this research. A corrugated web beam of plate is attached in the shear zone of the web as part of an experimental and theoretical investigation into plate girders. In experiments, seven plate girder specimens were tested under two points of load. Six of them were made of different shape of corrugated plate in the web, the last specimen was tested without corrugation as a reference specimen called control. In this study investigated the effected of (corrugation plate, thickness of corrugation with number layers of corrugated and the shape of corrugated plate) on (buckling and ultimate loads also on lateral and vertical deflection) and compared with reference specimen, these specimens have the same dimensions, the main variable was the thickness of the corrugated plate in the web (0.5, 1, and 2) mm, the depth was constant (300 mm). According to results of the experiment, the corrugated plates primarily increase the plate girder's stability. A corrugation of plate increases the buckling load and ultimate load significantly through the contribution of the corrugation to delay buckling of the plate girder in the web. In addition, it was found that increasing the plate-girder thickness leads to increased buckling and ultimate loads, because the stiffness will increase and delay the buckling. Also, the trapezoidal corrugation and the diagonal corrugate that placed perpendicular on the tension field action, give higher buckling and ultimate load than control beam. Ansys (version 17.0) computer program was used in this research represent the steel and nonlinear large structural shell was used to represent the corrugated web beam of the plate in the finite element analysis model.

Published: July 2023

Today, with the continuous increase in the use of computer networks and the rapid evolution of information technologies. The secure transmission of data over the Internet has become an urgent necessity to preserve the privacy of users and protect sensitive information from theft and distortion. images are most of this transferred data, so it was necessary to protect it by encrypting them using algorithms that ensure the protection of information access to the receiver. Color images contain sensitive information and details that must be secured and protected. This paper produces a comprehensive review of image encryption methods and classifies them based on various concepts such as chaotic maps, DNA, etc. with comparisons between existing approaches to accessing different security parameters. Additionally, the types of encryption keys were reviewed along with some common types of attacks and the most important methods for measuring encryption efficiency.
SURFACES OF DIAGONAL TRANSLATION OF VELAROIDAL TYPE ON A RHOMBIC PLANE
Authors:   Engineering Academy of the Peoples' Friendship University of Russia, KRIVOSHAPKO S.N.
Published: July 2023

The paper illustrates the application of the formulae of general type derived by the author earlier for the definition of surfaces of diagonal translation of superellipses of variable curvature on a rhombic plane. Explicit and parametric equations were derived additionally for the large group of surfaces of diagonal translation of congruent superellipses. For the both cases, the surfaces of velaroidal type are examined on rhombic plane. All of presented surfaces were visualized with the help of methods of computer graphics. Due to availability of arbitrary exponents of powers in explicit equations of generatrix superellipses of the main frame of a translation surface, design of surfaces of diagonal translation was broadened for the case of using plane algebraic curves instead of superellipses in the process of choice of main frame of projected surface of diagonal translation. The presented surfaces can find the application in architecture, civili engineering, and in machine building.

Authors: Winn Elizabeth , Kissane Madeleine , Merriel Samuel WD , Brain Thomas , Silverwood Victoria A , Whitehead Ishbel Orla , Howe Laura D , Payne Rupert A , Duncan Polly
Published: July 2023

Background

Older housebound people are an under-researched group for whom achieving good primary health care can be resource intensive.

Aims

To describe the characteristics and healthcare use of older (≥65 years) housebound people; explore clinician views on delivery of care to housebound people; and assess the feasibility of using a new network of healthcare professionals to deliver high quality research.

Design & setting

Retrospective observational study of electronic GP records and clinician survey in England.

Method

Clinical members of a new UK research network called the Primary care Academic CollaboraTive (PACT) will collect the data. For part A, around 20 GP practices will be recruited and clinicians will identify 20 housebound and 20 non-housebound people, matched by age and gender (around 400 total in each group). Anonymised data will be collected on characteristics (age, gender, ethnicity, deprivation decile), long-term conditions, prescribed medicines, quality of healthcare (via Quality Outcomes Framework targets), and continuity of care. Reports with benchmarked practice-level data will be provided to practices to identify areas for quality improvement and to enhance engagement. For part B, 2–4 clinicians will be recruited from around 50 practices in England (around 150 clinicians) to complete a survey about delivery of healthcare for housebound people. For part C, data will be collected to assess the feasibility of using the PACT network to deliver primary care research.

Conclusion

Older housebound people are a neglected group both in terms of research and clinical care. Understanding the characteristics and use of primary healthcare of housebound people will help identify how to improve their care.
IMPLEMENTING THE CONSTRUCTIVIST APPROACH OF THE FACE TO FACE TUTORIAL PROGRAM IN THE ACADEMIC WRITING COURSE
Authors: Pribadi Benny Agus
Published: July 2023

This study aims to elaborate on using a prospective approach to improve the effectiveness of students learning achievement in the Academic Writing tutorial : program. Thirty participants were involved in a series of face-to-face tutorial programs. The objective of this program –Academic Writing - is to help teachers who enroll in a distance learning program to be able to write adequate academic papers. Since the writing process is considered a mental constructive activity, the tutors must design and implement the constructivist learning perspectives in this course. To attain the course objective, the participants had to involve in several learning assignments that employed constructivist learning design. Six elements of the constructivist learning design - Situation, Groupings, Bridge, Questions, Exhibit, and Reflections - were applied in this research. The pre-test and post-test research designs were implemented in this study. Besides, the portfolio assessment was also used to assess the participants’ learning outcomes in completing their assignments - writing their academic papers. The study results show that implementing the constructivist approach significantly increases the motivation and the ability of the students to write academic papers in the Academic Writing course of the Teacher Education Program of Universitas Terbuka
O matriarcado africano na diáspora brasileira e suas contribuições para interpretação do espaço urbano
Authors: Antunes Ferreira Simone
Published: July 2023

Entendendo que o processo de colonização intensificou não só o racismo, mas também práticas patriarcais como elemento estruturante das sociedades modernas, o sentido (significado e direção) que a diferenciação e hierarquização de gênero feita pelas populações europeias desencadeou no fortalecimento do patriarcado exercido como dominação. Entretanto, as diferentes formas de matriarcado existentes e praticadas no continente africano foram recriadas na diáspora brasileira através de relações econômicas, políticas, culturais e religiosas a partir de ações comunitárias agenciadas por mulheres pretas. Nesse sentido, o objetivo deste estudo é trazer os valores Afro-civilizatórios sintetizados por Azoilda Loretto da Trindade somados a elementos básicos do pensamento afrocentrado de Cheikh Anta Diop, Molefi Kete Asante, Ama Mazama e Marimba Ani e do matriarcado africano sob a ótica de Ifi Amadiume e Oyèrónké Oyewùmí para compreendermos a centralidade, não homogênea, da figura feminina no continente africano e como essa forma de ser, estar, agir e pensar no mundo está ainda hoje inscrita nas paisagens urbanas brasileiras. Para isso se faz necessário despir-se de preconceitos normalizados dentro das ciências modernas e compreender a relevância das diferentes formas pelas quais as mulheres, usaram, se apropriaram do espaço urbano e forjaram cidades ao longo dos séculos XVIII, XIX e XX.
Presentación Dossier "Geografías, género y diversidades"
Authors: Ricci Carolina Paula , Lamego Mariana
Published: July 2023

Este dossier, como todo trabajo colectivo, tiene una historia de encuentros. Nos conocimos a raíz de la organización del XVIII Encuentro de Geografías de América Latina (EGAL) y VIII Congreso Nacional de Geografía de Universidades Públicas de la República Argentina realizado en Córdoba en el año 2021. Algunxs de quienes participamos en la comisión académica comenzamos a plantear la necesidad de pensar determinadas mesas temáticas que mostraran “otros” campos del saber o, mejor dicho, “otras formas de pensar y abordar” diversas tradiciones disciplinares. Allí surgió la idea de armar, dentro del eje teórico-metodológico, una mesa orientada al abordaje de la (r)existencia de “otras trayectorias geográficas” que mostraran diversos aspectos de la historia de la Geografía –sus sujetxs, saberes y contextos– por fuera del dogma disciplinar. En conversaciones con la Dra. Perla Zusman sugirió un trabajo articulado entre nosotras junto con el Dr. Paulo Albuquerque de Bomfin y la Esp. Rita Maldonado. Esa mesa –denominada “Otras trayectorias geográficas: historias y aportes conceptuales de las geografías silenciadas”– reunió diversos trabajos que desafiaron las formas tradicionales de abordar las temáticas, problemas e historias de las geografías y se constituyó el puntapié para el comienzo de un trabajo de cooperación entre ambas.

Authors: Silveira Mariana , Oliveira de Andrade Mauricio
Published: July 2023

O reduzido número de viagens por bicicleta realizadas por mulheres nas cidades do Brasil atrela-se normalmente à insegurança do trânsito e pública e à carência de infraestruturas cicloviárias. No entanto, fica cada vez mais evidente que o número de mulheres que usam a bicicleta vem aumentando aos poucos. Este artigo tem o objetivo de apresentar fatores que influenciam o uso da bicicleta por mulheres, considerando o uso do solo, a segurança do trânsito e a infraestrutura cicloviária da cidade do Recife. Usa da comparação de contagens de viagens de bicicleta em diferentes anos e tenta por testes estatísticos inferir sobre associações com fatores influentes ao uso da bicicleta. Traz em seus resultados que a variedade de uso do solo e a presença ou ausência de infraestrutura cicloviária interferem estatisticamente sobre as viagens de bicicleta feitas por mulheres.
Una lucha que alumbró un movimiento social
Authors: Coriat Silvia , Joly Eduardo
Published: July 2023

Este relato narra cómo una lucha por resguardar el derecho a la movilidad dio lugar a un movimiento social en defensa de los derechos de las personas en situación de discapacidad. Se trató del rechazo a la generación de barreras arquitectónicas en el ingreso a ascensores existentes en la Ciudad de Buenos Aires, resultado de una normativa que pretendía garantizar la seguridad en su uso. En esta lucha se enfrentaron, por un lado, organizaciones de y para personas en situación de discapacidad, reclamando accesibilidad y, por otro lado, un lobby conformado por fabricantes de ascensores y el gremio de encargados de edificios de propiedad horizontal, supuestamente abogando por la seguridad de los usuarios (en particular, la de los niños), pero en los hechos defendiendo una trama de intereses económicos. El enfrentamiento se desplegó en los tres poderes del Estado (ejecutivo, legislativo y judicial), en el Instituto Argentino de Normalización y Certificación (IRAM) y en los medios de comunicación. En el transcurso de esta lucha se conformó la Red por los Derechos de las Personas con Discapacidad (REDI).

Background: Hookah, as a traditional method of smoking, is widely used in Iran, especially in Bushehr province. It is essential to identify the most important determinants of modifying hookah smoking behavior. This study aimed to investigate the predictors of the stages of change in quitting hookah smoking in 15-60-year-old individuals in Bushehr province, southern Iran, based on the transtheoretical model (TTM). Methods: This descriptive-analytical study was conducted on 1173 Hookah smokers in Bushehr province. The samples were selected by two-stage random sampling from 10 cities. Data were collected using a valid and reliable questionnaire consisting of 5 sections (demographic characteristics, stages of change, processes of change, decisional balance, and self-efficacy). Data were analyzed by R version.3.3.1 using analysis of variance and ordinal logistic regression at a significant level of 0.05. Findings: The data revealed 82% of the participants were in the preparatory phase (55.3% in pre-contemplation and 26.7% in contemplation stages). Marital status, family members smoking hookah, cigarette smoking, level of education, number of family members, number of quitting attempts, self-efficacy, self-reevaluation, counter-conditioning, reinforcement management, and stimulus control were predictors of quitting hookah smoking. Conclusion: Given that most study participants were in the inactive stages of quitting hookah smoking, it seems necessary to design and implement behavioral interventions based on the predictive TTM constructs in this population.
