As part of the New Nets Project, new insecticide-treated net (ITN) types, Interceptor® G2 (BASF) (IG2) and PermaNet® 3.0 (Vestergaard SA) (PBO), were included in a select number of districts during the 2019 universal coverage campaign in Burkina Faso. This manuscript describes the results of the observational study that accompanied the IG2 and PBO distributions, designed to evaluate their effectiveness and incremental cost-effectiveness compared to standard pyrethroid-only ITNs (Interceptor®) in the unique Burkinabe context.
Methods
The observational study design used enhanced surveillance within the study districts of Gaoua, Banfora, and Orodara. Activities included annual cross-sectional surveys during peak transmission seasons, monthly entomological surveillance, monthly passive case detection using routine surveillance systems, and qualitative studies on human behavior and ITN use patterns. Collected data compared changes in malaria transmission, disease burden, and vector behavior in districts receiving one of the new net types to the district receiving standard pyrethroid-only ITNs from 2019 to 2022.
Results
The ITN distribution campaign increased net ownership and use across all study districts. Two years after mass campaigns, ITN ownership (above 90%) and use (above 85%) in IG2 and PBO districts remained high, though use was under 40% in the standard ITN district. The entomological data showed that total biting rates declined in Gaoua (standard ITNs) and Banfora (IG2s). In Orodara, the PBO district, mosquito biting rates increased slightly. However, prevalence among children under 5 years old fell by a greater magnitude in Orodara—from 28.4% in 2019 to 3.7% in 2020. The overall reductions in malaria case incidence rates were significant for both types of next generation ITNs (19% greater reductions associated with IG2 and 25% greater reductions associated with PBO), and in each case the improved effect relative to standard ITNs was well sustained for the duration of the study.
Conclusions
Changes in under 5 prevalence and all-age incidence from baseline to Year 1–3 clearly showed that ITN distribution campaigns were associated with reductions in malaria transmission, independent of ITN type; but the reductions were more effective and sustained in the PBO and IG2 ITN districts compared to the standard ITN district.

Published: August 2023

The miniaturization of microfluidic systems plays a pivotal role in achieving portability and compactness. However, conventional microfluidic systems heavily rely on external bulky facilities, such as syringe pumps and compressed air supplies, for continuous flow, which restricts their dissemination across various applications. To address this limitation, micropumps have emerged as a potential solution for portable power supply in microfluidic systems, with piezoelectric micropumps being widely adopted. Nonetheless, the inherent pulsatile mechanism of piezoelectric micropumps leads to unstable flow, necessitating appropriate mitigation for applications requiring flow stability. This research introduces an innovative hybrid pumping system that integrates a wirelessly controlled micropump with a 3D-printed modular microfluidic low-pass-filter. The primary objective of this system is to offer a portable and stable flow source for microfluidic applications. The system design and characterization are based on a three-element circuit model. Experimental results demonstrate a highly stabilized flowrate of 657 ± 7 µL/min. Furthermore, the versatility of the system is showcased by successfully forming droplets with a polydispersity ranging from 1.5–4%, comparable to that of bulky commercial pumping systems. This hybrid pumping system offers a promising solution for applications necessitating portable and stable flow sources, and its reconfigurability suggests potential integration into multifunctional microfluidic platforms.

Published: August 2023

Background
This study was conducted to investigate the expression patterns and biological roles of urinary long non-coding RNAs (lncRNAs) and messenger RNAs (mRNAs) in individuals diagnosed with lupus nephritis (LN).
Methods
The study cohort comprised six participants: three with systemic lupus erythematosus (SLE) involving LN, three with SLE without LN, and three healthy controls (CON). Microarray technology was employed to analyze urinary mRNAs and lncRNAs, thereby exploring alterations in overall RNA expression. Functional insights into dysregulated differentially expressed mRNAs (DEMs) associated with LN were derived through gene ontology (GO) enrichment analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, and gene set enrichment analysis (GSEA). Furthermore, the construction of a protein-protein interaction (PPI) network was accomplished using the Search Tool for the Retrieval of Interacting Genes/Proteins (STRING). The identification of immune-related cell types was facilitated by Single-sample Gene Set Enrichment Analysis (ssGSEA). To predict potential drug candidates based on differentially expressed genes (DEGs), Connectivity Map (CMap) analysis was conducted.
Results
Within the urine samples of SLE patients, a total of 247 mRNAs and 602 lncRNAs exhibited differential expression relative to the control group. Among these, 83 down-regulated and 141 up-regulated DEMs were specifically discerned in patients with LN. GO analysis of the network highlighted enrichment in processes such as transcriptional regulation, intrinsic apoptotic signaling pathways in response to DNA damage, and the regulation of mitophagy. KEGG pathway analysis primarily revealed enrichment in protein processing within the endoplasmic reticulum, apoptosis, and the P53 signaling pathway. Co-expression and PPI network analysis suggested that nodes with higher degrees of connectivity were concentrated in pathways related to apoptosis and autophagy. An assessment of immune infiltration unveiled a correlation between activated B cells and CD56dim natural killer (NK) cells with LN pathogenesis. The prediction of drugs implicated inhibition of mechanistic Aurora kinase A (AURKA) as a primary targeted intervention. The molecular docking process confirmed the robust binding activity of hub genes' components.
Conclusion
This study has illuminated the distinct expression profiles of urinary long non-coding RNAs (lncRNAs) and messenger RNAs (mRNAs) in lupus nephritis (LN) patients. These profiles, particularly in the context of apoptosis, autophagy, and immune cell involvement, provide valuable insights into LN's underlying mechanisms. The identification of potential therapeutic targets, such as mechanistic AURKA, offers promising directions for future interventions in LN management.

Authors: Ma Chao , Zhang Yixia , Li Zhiguang , Zhou Change , Li Rong
Published: August 2023

A novel halogen-free, formaldehyde-free, phosphorus-nitrogen-based flame retardant (FR), ammonium salt of erythritol phosphoric ester acid (AEPEA), was synthesized and coated onto cotton fabrics to increase the flame resistance of cotton. The structure of AEPEA was characterized by hydrogen nuclear magnetic resonance (1H NMR). Fourier-transform infrared(FTIR) and X-ray photoelectric spectrometer (XPS) results proved that AEPEA was chemical grafted on the cotton through P-O-C bond. The limiting oxygen index (LOI) of cotton treated with 300 g/L AEPEA reached 40.1% and the carbon length was 4.2 cm. After 50 laundering cycles (LCs), the LOI value could still reach 27.8%. Thermo-gravimetric (TG) and cone calorimetry test (CCT) were used to further investigate the flame retardancy and thermal stability of cotton fabric, and the results proved that the thermal stability of treated cotton was greatly improved. Scanning electron microscopy (SEM) showed that there was no significant change on the surface of treated cotton. The results of X-ray diffraction (XRD) showed that the crystalline morphology of cotton fabric was almost unchanged after flame-retardant finishing. Besides, the mechanical properties of the treated cotton only decreased slightly.

Out-of-equilibrium dynamics of two interacting optically-trapped particles
Authors: Dotsenko Victor S , Imparato Alberto , Viot Pascal , Oshanin Gleb
Published: August 2023

We present a theoretical analysis of a non-equilibrium dynamics in a model system consisting of two particles which move randomly on a plane. The two particles interact via a harmonic potential, experience their own (independent from each other) noises characterized by two different temperatures T_1T1 and T_2T2, and each particle is being held by its own optical tweezer. Such a system with two particles coupled by hydrodynamic interactions was previously realised experimentally in Bérut et al. [EPL 107, 60004 (2014)], and the difference between two temperatures has been achieved by exerting an additional noise on either of the tweezers. Framing the dynamics in terms of two coupled over-damped Langevin equations, we show that the system reaches a non-equilibrium steady-state with non-zero (for T_1 \neq T_2T1≠T2) probability currents that possess non-zero curls. As a consequence, in this system the particles are continuously spinning around their centers of mass in a completely synchronized way - the curls of currents at the instantaneous positions of two particles have the same magnitude and sign. Moreover, we demonstrate that the components of currents of two particles are strongly correlated and undergo a rotational motion along closed elliptic orbits.
Effects of aerosol emission changes on sea ice concentration and thickness in the Russian Arctic during the 2020 lockdown
Authors: Panicker Dency V. , Vachharajani Bhasha H. , Srivastava Rohit
Published: August 2023

During the COVID-19 lockdown, large industries in the Russian Arctic region were closed for two months, leading to a significant reduction in anthropogenic aerosol emissions. This decline in aerosols resulted in a decrease in the human-made aerosol cooling effect. The strict lockdown measures implemented after 18 March 2020 caused a drastic downward fall in considered aerosols. Consequently, there was an impact on air temperature, with temperature differences exceeding 3 K in November and February, while clear-sky top net solar flux values were greater than 13 W m−2. Throughout the lockdown period, the Russian Arctic's annual area average sea ice concentration was 7.72% in 2019 and 7.64% in 2020. The decrease in radiation-scattering pollutants contributed to an increase in global warming. Some pollutants, like sulfur, carbon dioxide, and methane, produced a cooling effect by mitigating greenhouse gases, which could affect the speed of sea ice melt. However, due to the short duration of the pandemic, it remains challenging to determine whether the aerosol changes accelerated or decelerated the sea ice melting process.
MiRNAs: Emerging Agents for Therapeutic Effects of Polyphenols on
Ovarian Cancer
Authors: Badehnoosh Bita , Rajabpoor Nikoo Nesa , Asemi Reza , Shafabakhsh Rana , Asemi Zatollah
Published: August 2023

In terms of female reproductive tract cancers, ovarian cancer remains the principal reason
for mortality globally and is notably difficult to identify in its early stages. This fact highlights the
critical need to establish prevention strategies for patients with ovarian cancer, look for new robust
diagnostic and prognostic markers, and identify potential targets of response to treatment. MicroRNAs
(miRNAs) are one of the novel treatment targets in cancer treatment. Thus, understanding the part of
miRNAs in the pathogenesis and metastasis of ovarian cancer is at the center of researchers' attention.
MiRNAs are suggested to play a role in modulating many essential cancer processes, like cell proliferation,
apoptosis, differentiation, adhesion, epithelial-mesenchymal transition (EMT), and invasion.
In two recent decades, natural polyphenols' anti-cancer features have been a focal point of research.
Meanwhile, polyphenols are good research subjects for developing new cancer treatments. Polyphenols
can modify miRNA expression and impact the function of transcription factors when used as dietary
supplements. Multiple works have indicated the impact of polyphenols, including quercetin,
genistein, curcumin, and resveratrol, on miRNA expression in vitro and in vivo. Here, we provide an
in-depth description of four polyphenols used as dietary supplements: quercetin, genistein, curcumin,
and resveratrol, and we summarize what is currently known about their regulatory abilities on influencing
the miRNA functions in ovarian tumors to achieve therapeutic approaches.

Published: August 2023

Background:

In developing countries, pulmonary infections are one of the major causes of death because the incidence and prevalence of pulmonary diseases have increased dramatically. Several species of protozoa can be found in the respiratory system. Pulmonary protozoan infections are increasingly identified in clinical settings. Protozoans within the genus Lophomonas are endo-commensals of the hindgut of arthropods. Recently the trophozoite forms of Lophomonas have been observed in human tissues. Little is known about the occurrence of these protozoa in the Iranian population.

Objective:

This study was designed to determine the prevalence of Lophomonas in bronchoalveolar lavage specimens from the patients with respiratory diseases referred in Kerman province, southeast of Iran.

Methods:

A total of 200 patients were selected by simple random sampling. BAL samples were transferred to the Parasitology lab, direct smears were prepared for each specimen and two staining methods, Giemsa and Trichrome were performed for Lophomonas microscopical identification. The data were analyzed using descriptive statistics and Chi-square test.

Results:

Lophomonas trophozoites were found in 48 (24%) patients, at least in one of the methods. The mean age of the patients was 58.3 years (58.1 in men, 58.4 in women). Out of 200 samples, 45 (22.5%), 30 (15%), and 11(5.5%) were positive by wet mount microscopy, Giemsa, and Trichrome staining, respectively.

Conclusion:

This study presented the first finding of Lophomonas infection in patients with pulmo-nary symptoms in southeast Iran.
Intrapancreatic Accessory Spleen Diagnosed by Size Reduction after
Immunosuppressive Therapy: A Case Report
Authors: Tursem Tokmak Turgut , Burak Lacin Mahmut , Gencer Humeyra
Published: August 2023

Background:

Intrapancreatic accessory spleen (IPAS) is a congenital entity that can be confused with malignant distal pancreatic masses. Radiologic imaging and radionuclide imaging have an important place in the diagnosis of IPAS.

Case report:

Blood tests were performed on a 36-year-old female patient who presented with tachypnea, tachycardia, pain in the joints, and pain in the left abdominal quadrant. Laboratory test results were as follows: hemoglobin value 6.0 mg/dl, sedimentation 120, aspartate transaminase (AST) 150U/L, and alanine transaminase level (ALT) 110U/ L. Additional laboratory tests and ultrasonography were performed. The anti-double-stranded DNA (dsDNA) level was 800 IU/ml. C3 and C4 values were both 0.64 IU/ml, with anti-Ro-52 +++(three positive) and anti-Ro-60 ++ (two positive). A clinical diagnosis of systemic lupus erythematosus (SLE) was made. Ultrasonography and dynamic contrast-enhanced upper abdominal MRI showed lesions suggestive of multiple hemangiomas in the liver and a 29x18 mm lesion in the tail of the pancreas with a similar appearance as the spleen. SLE treatment was started. Scintigraphy was recommended for the diagnosis of IPAS. Scintigraphy was performed in the third week of the treatment. Uptake was not observed. In the second month of the treatment, a control upper abdominal MRI was performed, and a decrease in the size of the lesion was observed.

Conclusion:

IPAS can be confused with pancreatic masses. Lack of uptake in scintigraphy may be due to treatment protocols that produce low phagocytic activity. If radiological imaging findings are compatible, a reduction in lesion size after immunosuppressive therapy can be accepted as evidence for the diagnosis of IPAS.

Authors: Wang Bonnie , Nagaraja Vivek
Published: August 2023

Background:

Fibrotic interstitial lung disease is an important driver of morbidity and mortality in patients with connective tissue diseases (CTD). Due to the lack of prospective randomized trial data in this population, practice pattern variation exists in the management of patients with CTD.

Case Presentation:

This case series describes three patients, each with a different background of autoimmunity complicated by fibrotic interstitial lung disease (ILD). We review their initial presentations, follow their disease trajectories on currently available treatments, and reference forthcoming clinical trials.

Conclusion:

Clinical impact or potential implications. Response to immunosuppression and antifibrotic therapy is variable in patients with connective tissue disease-related fibrosing interstitial lung disease. Data from prospective clinical trials and longitudinal registry studies will conceivably provide additional insight into improving care for these patients.

Published: August 2023

Among the different strategies applied in recent years for the development
of green extraction techniques in food analysis, the design and use of deep eutectic
solvents (DESs) have aroused the utmost attention due to the advantages provided by
these materials in terms of sustainability and versatility. Different types of DESs have
been applied in this field including hydrophilic and hydrophobic mixtures, natural
DESs, or polymeric-DESs. In this sense, the great availability of components and the
wide range of possible combinations constitute potential tools to increase the selectivity
and enhance the extraction capacity of the procedures, which is an important concern
when complex food samples are tackled. This broad spectrum of possibilities has
allowed the extraction of diverse compounds including not only contaminants such as
pesticides, plastic migrants, heavy metals, or pharmaceuticals, among others, but also
the extraction of biomolecules from food and food by-products. However, despite the
advantages of these materials, there are important drawbacks like their high viscosity
and low volatility that limit their application. In this context, an important effort has
been carried out by the study of different combinations and the development of
numerous approaches. In this chapter, the most relevant applications of DESs in the last
five years in food analysis have been compiled and discussed in order to provide a
global view of the advantages and limitations of the application of these green
extraction solvents in the field. Additionally, the current trends and future perspectives
in the use of DESs in food analysis are also pointed out.

Se ejemplifica el término de Mímesis analógica como recurso literario, y marca la diferencia con respecto a la conceptualización platónica como copia. Asimismo, la Mímesis analógica se apoya en la Mímesis que Paul Ricœur desarrolla en su trabajo teórico. El concepto por tratar conlleva el pensamiento del autor a manera de doxografía y encierra una verdad metafórica.  Lo anterior se expone en relieve con la cuentística de Juan José Arreola, donde el autor elabora una recreación de su pensamiento y lo manifiesta dentro de su narrativa. El método que se utiliza en la aplicación es la Hermenéutica analógica de Mauricio Beuchot.

Authors: Lee Hyeonhoon
Published: August 2023

Background

ChatGPT (Open AI) is a state-of-the-art artificial intelligence model with potential applications in the medical fields of clinical practice, research, and education.

Objective

This study aimed to evaluate the potential of ChatGPT as an educational tool in college acupuncture programs, focusing on its ability to support students in learning acupuncture point selection, treatment planning, and decision-making.

Methods

We collected case studies published in Acupuncture in Medicine between June 2022 and May 2023. Both ChatGPT-3.5 and ChatGPT-4 were used to generate suggestions for acupuncture points based on case presentations. A Wilcoxon signed-rank test was conducted to compare the number of acupuncture points generated by ChatGPT-3.5 and ChatGPT-4, and the overlapping ratio of acupuncture points was calculated.

Results

Among the 21 case studies, 14 studies were included for analysis. ChatGPT-4 generated significantly more acupuncture points (9.0, SD 1.1) compared to ChatGPT-3.5 (5.6, SD 0.6; P<.001). The overlapping ratios of acupuncture points for ChatGPT-3.5 (0.40, SD 0.28) and ChatGPT-4 (0.34, SD 0.27; P=.67) were not significantly different.

Conclusions

ChatGPT may be a useful educational tool for acupuncture students, providing valuable insights into personalized treatment plans. However, it cannot fully replace traditional diagnostic methods, and further studies are needed to ensure its safe and effective implementation in acupuncture education.
Study Work on Parabolic Solar through Water Heating system with Various Type of Coating on Reflectors with or without Glass
Authors: Singh Dashrath
Published: August 2023

Abstract: Solar energy serves as the wellspring of all forms of energy present on Earth, establishing its role as a significant contributor. The contemporary surge in global energy demand exerts pressure on traditional energy reservoirs, including coal, petroleum, natural gas, and fossil fuels. These resources, limited in nature, face potential depletion in the absence of recourse to alternative sources. Solar energy emerges as a viable substitute for diverse energy production processes due to its renewable attributes, devoid of any contribution to the emission of greenhouse gases or environmental contaminants. Furthermore, its enduring nature safeguards against imminent depletion. This study delves into the prospect of harnessing solar energy for hot water generation through a thermal system. The research involves the construction of a solar radiation tracking system operated manually. A comparative evaluation ensues, featuring parabolic trough solar water heaters utilizing distinct reflector materials, both with and without the incorporation of glass covers. The reflective component materializes as a stainless steel sheet-formed trough, skillfully cut and welded, integrated with aluminum foil and mirror strips for reflective enhancement. Functioning as the absorber, a copper tube boasting an 18mm diameter and 240mm focal length is adopted. The experimental protocol spans four phases, each involving varying reflector configurations, including instances with and without a glass cover affixed to the trough's surface to mitigate wind-induced losses below. Performance metrics are meticulously documented, subsequently subjected to comparison against three alternative scenarios. The experimentation transpired within the precincts of SRCEM College, Banmore, during the summer season of May 2023, situated in the region of Madhya Pradesh, India. The study's culmination sheds light on the potential of solar thermal systems for hot water generation. The insights gained from the comprehensive evaluation of parabolic trough solar water heaters, encompassing diverse reflector configurations and the influence of glass cover presence, lay the groundwork for a potential revolution in sustainable energy utilization. Amidst the contemporary energy conundrum, this research unveils innovative avenues that harness the abundant offerings of solar energy, promising a cleaner and enduring energy landscape.

Authors: Li Hu , Su Lingjie , Wang Jichen , Song Wenying , Tu Huaiyang , Huang Shiqi
Published: August 2023

Focusing on gender role theory and the queen bee phenomenon, this study explored the differentiated exchange relationships between leaders and subordinates with different gender composition, and their influence on leader empowering behavior. We collected data from 1,211 subordinates
of 286 teams at a Fortune 500 company in China through the questionnaire method. The empirical analysis results showed that the leader-member exchange relationship of the woman leader-woman subordinate composition was lower than that of the man leader-man subordinate composition, which further
reduced leader empowering behavior. This study further used man leader-woman subordinate and woman leader-man subordinate compositions as control groups to verify the effectiveness of the queen bee phenomenon. We concluded that the queen bee phenomenon alone does not significantly affect leader
empowering behavior, but that the combination of gender stereotypes and queen bee phenomenon has a significant effect.

Authors: Mascarenhas Higor Alexandre Duarte , Magela Thiago
Published: August 2023

Introdução: O êxodo de indivíduos por diversos motivos ou circunstâncias vem ao longo dos últimos anos aumentando de forma significativa no cenário brasileiro e mundial. Um dos motivos identificados para esse fluxo migratório é a formação acadêmica desses indivíduos, que buscam se capacitar em instituições de ensino de melhor qualidade. Objetivos: este trabalho tem como objetivo analisar dados sobre a produção científica e formação acadêmica dos doutores brasileiros, visando entender o quão a mobilidade acadêmica afeta na produção científica dos doutores brasileiros. Metodologia: Para tanto foi necessária a extração dos dados de formação acadêmica, a partir dos currículos de indivíduos cadastrados na Plataforma Lattes. Assim sendo, selecionou-se todos os indivíduos com doutorado concluído, agregando 381.463 currículos. Resultados: Como resultados, foi possível efetuar uma análise da mobilidade acadêmica dos doutores brasileiros e correlacionar com os dados sobre a produção científica destes indivíduos, com o intuito de explorar como evolui a produção científica dos doutores brasileiros ao longo de seu processo de formação acadêmica, e ainda, mensurar como a mobilidade influencia as suas pesquisas. Conclusão: Doutores brasileiros têm uma maior produção científica após a migração, com predileção por periódicos de alto impacto (qualis A1 e A2). Além disso, preferem publicar em inglês, português e espanhol.
Colaboração Científica Internacional em Genética: um estudo sobre a divisão de tarefas entre pesquisadores do Sul e do Norte Global
Authors: Costa Michelli Pereira da , Gomes Graziela Barros
Published: August 2023

Introdução: Este artigo examina a questão da colaboração científica entre pesquisadores de diferentes países no campo da genética. Especificamente, ele se concentra na divisão de tarefas e na influência da origem dos pesquisadores nos processos de coleta, análise e teorização de dados científicos. Metodologia: A metodologia de pesquisa utilizou uma combinação de métodos qualitativos e quantitativos, incluindo pesquisa documental e de levantamento. O estudo analisou o campo de contribuição de autoria nas publicações científicas da área para verificar as atribuições de tarefas de cunho teórico e operacional realizando, complementarmente, a identificação da origem geográfica dos autores. Resultados: O estudo constatou que, em geral, não houve viés significativo na atribuição de tarefas aos autores com base em sua origem. No entanto, o estudo revelou que países centrais tendiam a dominar a execução das tarefas científicas. Esse resultado indica um possível desequilíbrio de poder no processo de colaboração científica, com os pesquisadores do Sul global potencialmente sendo marginalizados no processo. Conclusão: O artigo destaca os potenciais benefícios do movimento de acesso aberto na promoção da participação equitativa de autores do Sul global. Ainda assim, também ressalta a necessidade de democratização de outras estruturas no processo de colaboração científica para garantir a democratização da ciência. Portanto, a pesquisa sugere que, embora possa não haver uma tendência significativa na atribuição de tarefas aos autores com base em sua origem, o desequilíbrio de poder na colaboração científica ainda existe.

Authors: Cristovão Henrique Monteiro , Vale Lucas dos Santos do
Published: August 2023

Introdução: o Workshop de Informação, Dados e Tecnologia (WIDaT) está em sua sexta edição em 2023. As cinco edições anteriores somam 151 artigos publicados nos anais, com a participação de 267 autores vinculados a 49 instituições em 5 países. O objetivo da pesquisa é revelar clusters entre autores e entre instituições. Metodologia: pesquisa qualitativa de natureza aplicada que se utiliza, sobretudo, de técnicas de visualização de informação com o apoio de métodos de análise de redes sociais. Resultados: redes de informação monopartidas entre autores e entre instituições com a indicação de clusters por meio de palavras chave dos artigos. Conclusão: as redes de autores e de instituições por meio de palavras chave ampliou a densidade de conexões comparativamente com as mesmas redes por meio da coautoria. A formação de clusters de autores e de instituições sinalizou possibilidades potenciais de aproximação entre autores com intuito de parcerias conforme suas áreas de atuação representadas por palavras chaves de suas publicações.

Published: August 2023

Introdução: Trabalho decorrente de projeto em andamento desde 2022 na temática violência contra mulher, em suas vertentes de atendimento e de proteção, e em seus módulos de informação cadastral, bibliográfica e estatística, com vistas a futuro desenvolvimento de um sistema de informação do tipo Current Research Information Systems (CRIS) temático, reunindo ciclo de vida da pesquisa e ciência de dados. Na fase inicial, explora o módulo projetos de pesquisa. Metodologia: Levantamento manual de registros de projetos no Diretório dos Grupos de Pesquisa no Brasil (DGP), seguido de emprego de metodologias e técnicas no âmbito das ciências dos dados, com levantamento parametrizado por linha de pesquisa na temática “mulheres em situação de vulnerabilidade”, orientado por palavras-chave que a qualificam. Resultados: 302 grupos de pesquisa em 114 Instituições de Ensino Superior dão origem a múltiplas análises, desde sua distribuição geográfica (34% no Nordeste e 32% no Sudeste), seguidos de análise temporal cumulativa, ao longo de 40 anos (1983-2022), dos quais 90% deles ganham proeminência no século XXI com a escalada do feminicídio e da violência contra mulheres, constatação referendada pelas principais linhas de pesquisa, intercambiando termos intimamente conectados, mobilizando cerca de 6.100 colaboradores (35% doutores e 19% mestres). A futura agregação de módulo de visualização de dados suscita discussão sobre dificuldade e atualidade de dados estatísticos no campo da violência contra mulher, inserida em uma complexa e intrincada rede de relações. Considerações Finais: O futuro desenvolvimento de um sistema CRIS sinaliza para o caráter inovador de políticas públicas ancoradas em pesquisa de intervenção recomendada pela Organização Mundial da Saúde.
