Published: August 2023

Introduction. One of the important and unresolved issues of pediatric gastroenterology remains study of inflammation mechanisms of the stomach’s mucosa, as well as factors that regulate inflammatory reactions. Nowadays, there are many studies devoted to the research of the nuclear role of factor kappa B (NF-kB) in the regulation of the level of gene expression that control proliferation, cell apoptosis, angiogenesis, and determine the nature and expressiveness of the inflammatory process in adults. However, there are no conclusion regardless the role of NF-kB in the regulation of the mechanisms of inflammation development in the stomach’s mucosa of chronic gastritis (CG) in children. Purpose - to study the level of NF-κB activity depending on the degree of gastric mucosa inflammation of chronic gastritis in children. Materials and methods. We observed 76 children aged 8-16 years with verified chronic gastritis. To verify the diagnosis, all children underwent a morphological examination of the stomach’s mucosa in the fundal and antral departments of the stomach. An indirect streptavidin-peroxidase method of protection using polyclonal antibodies to NF-kB was used for immunohistochemical research. Results. On the basis of the morphological study of gastric biopsies, we discovered inflammatory changes based of lymphocytic infiltration, microcirculatory disorders of the stomach’s mucosa with the subsequent development of stroma lamina propria fibrosis. During the immunohistochemical study of gastric biopsies, a high level of NF-kB expression was noted in the cytoplasm with a pronounced degree of inflammation, atrophy, and lymphocytic infiltration of the stomach’s mucosa. Conclusions. The results of the study indicate the morphological signs of the formation of an early chronic inflammatory process in gastritis in children. The transcription factor NF-kB determines the level of inflammatory activity and plays a leading role in the mechanism of development of chronic gastritis in children. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of the participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interests was declared by the author.

Purpose - to determine the frequency and prevalence of rhinogenic orbital complications (RОC) in children with acute rhinosinusitis (ARS) depending on their gender and age, with an analysis of the treatment performed in the pediatric ENT department. Materials and methods. A retrospective analysis of 61 patients with ROС at АRS in children who were treated in the otorhinolaryngology department of the City Children’s Hospital No. 1 in Kyiv from 2016 to 2020 was conducted. The diagnosis was established on the basis of the anamnesis, general clinical examination, endoscopic examination and radiological methods of diagnosis (X-rays or CT of paranasal sinuses). All patients received complex treatment with a parenteral antibiotic and were examined by related specialists: an ophthalmologist, a pediatrician, a neurologist or a neurosurgeon as needed. Results. The average age of the patients was 5 years and 2 months. There were 34 (55.7%) boys, 27 (44.3%) girls. In 38 (62.3%) sick children, reactive swelling of the eyelids of the right eye was diagnosed, in 22 (36.1%) reactive swelling of the eyelids of the left eye, in one (1.6%) case, periostitis of the right orbit was diagnosed. All patients with ROС on the background of АRS received parenteral antibacterial therapy with one or two drugs, among which ceftriaxone was prescribed in 98.3%, metrogyl in 41%, macrolide in 21.3%, and amoxicillin in 1.6% of cases. 3 (5%) patients underwent surgical treatment - puncture and drainage of the maxillary sinus, 2 (3.7%) sick children underwent frontotomy with sinus drainage. Complex conservative treatment without surgical intervention was effective in 56 (91.3%) patients. The average length of hospital stay was 7.7 days. Conclusions. In children with АRS, ROС occurs most often at the age of 3 to 7 years (49.2%) and manifests itself in the form of reactive swelling of the eyelids of the right eye in 62.3% and in 36.3% of the left eye. Timely antibiotic therapy in patients with АRS of children with ROС makes it possible to effectively treat this pathology without the use of surgical methods. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of the participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interests was declared by the authors.

Quorum sensing (QS) is the interaction of bacteria cell-to-cell to regulate various bacterial functions, including bacterial virulence. It has been suggested that QS interruption is an anti-infective strategy to combat diseases in aquaculture. This research was conducted to isolate the potential probiotics bacteria as QS degrader from the fish gut and investigate its efficiency in reducing Aeromonas hydrophila pathogenicity by in vitro and in vivo assay. In this study, three isolates from the fish gut were able to degrade N-acyl homoserine lactone (AHL), one of the QS signals of A. hydrophila. Based on 16S rDNA sequence analysis, isolate CPi12 was identified as Klebsiella sp., CBa5 and CBa7 were identified as Enterobacter tabaci. These isolates were co-cultured with A.hydrophila for five days. Results revealed that all isolates could decrease the AHL production of A. hydrophila but did not affect the growth of the pathogen. In vivo assay results showed that isolate CPi12 reduced the pathogenicity of A.hydrophila against tilapia with a significantly higher survival rate (p<0.05) of fish in the CPi12-fed group than the control group. Meanwhile, isolate CBa7 was significant (p<0.05) for growth performance, including specific growth rate (SGR), weight gain (WG), feed conversion ratio (FCR), mean weight gain (MWG), and average daily growth (ADG) among whole treatment and control group. These results displayed that the probiotics bacteria as QS degrader isolated from the fish gut could control the pathogenicity of Aeromonas hydrophila. It has been proposed that QS degrader bacteria might be an alternative solution for disease control.
Astronism and the Astronic Religious Tradition
Authors: Cometan  , York Michael
Published: August 2023

A new religion was founded in 2013 that goes by the name of Astronism while its community of followers are known as Astronists. This article gives a rigorous account of the eschatology, soteriology and worldview of this new space religion while contextualizing its emergence as part of a broader Astronic religious tradition. This proposed tradition may itself possess prehistoric roots in the Upper Palaeolithic in the earliest human observations of the night sky. Human beings in turn came to establish a relationship with celestial phenomena, one of both spiritual and secular utility that has since produced systems of astrotheism and astrology. In the contemporary, the projection of the Astronist theory of history onto the Astronic tradition has meant that Astronism’s salvific doctrine of transcension is established as a grand narrative and universal ethic that unites the Astronic tradition. In essence, this article considers how Astronism, as a new religious movement, is working to revive astronomical religion, albeit in ways relevant in an age of space exploration and appropriate to modern scientific knowledge about humanity’s true place in the universe.

War is Not Over
Authors: Westbrook Donald A
Published: August 2023

This article offers a brief introduction to the institutional history of the Church of Scientology in France (1959–present) before turning attention to the current state of Scientology in relation to state-sponsored anti-cultism and laïcité. In France, groups regarded as “sectes” (cults) are monitored by the French government’s MIVILUDES (Mission interministérielle de vigilance et de lutte contre les dérives sectaires, the Interministerial Mission of Vigilance and Combat against Cultic Deviances). As of late 2022, MIVILUDES is overseen within the French government by Sonia Backès, Secretary of State (Deputy Minister) for Citizenship. Backès, a former Scientologist, was raised in the Church of Scientology, completed Scientology courses, and attended a “Study Tech” school that made use of the educational methods of L. Ron Hubbard, among other aspects of participation, before ceasing activity in the group as a teenager. Backès has become a vocal opponent of Scientology, claiming she escaped from the group in an exit narrative that is disputed by family members. Backès’s apparent transformation from an “ordinary leave-taker,” “defector,” or “invisible former member” to a highly vocal “apostate” serves as a case study of a new expression of Scientology ex-member identity that is not well examined in the NRM literature on apostasy and disaffiliation—that of a second-generation (former) member in a position of political power. In a country like France, this form of political power can be operationalized and weaponized against new or minority religions such as Scientology, all with the backing of the state.
ONE-CLASS FUSION-BASED LEARNING MODEL FOR ANOMALY DETECTION
Authors: Bui Cong Thanh , Cao Van Loi , Hoang Minh , Nguyen Quang Uy
Published: August 2023

The Dempster-Shafer (DS) theory of evidence is frequently used to combine multipe supervised machine learning models into a robust fusion-based model. However, using the DS theory to create a fusion model from multiple one-class classifications (OCCs) for network anomaly detection is a challenging task. First, the lack of attack data leads to the difficulty in estimating an appropriate threshold for the OCC models to distinguish between normal and abnormal samples. Second, it is also very challenging to find the weight of OCCs that corresponds to the contribution of each OCC model in the fusion model. In this paper, we attempt to solve the above issues in order to make the DS theory applicable for constructing OCC-based fusion models. Specifically, we propose two novel methods for automatically choosing the appropriate threshold of OCCs and for estimating the weight of individual OCCs in fusion-based models. Thanks to that, we develop an One-class Fusion-based Anomaly Detection model (OFuseAD) from multiple single OCCs. The proposed model is evaluated on ten well-known network anomaly detection problems. The experimental results show that the performance of OFuseAD is improved on almost all tested datasets using two metrics: accuray and F1-score. The visualization results provides the insight into the characteristics of OFuseAD.

The study was carried out to investigate lipid and protein oxidation of herring (Sardinella gibbosa) that was treated with (2.5% w/v) sodium acetate at 4oC. After 3, 6, 9, and 12 days, lipid and protein oxidation were evaluated by indications such as pH value, peroxide (PV), thiobarbituric acid-reactive substances (TBARS), protease enzyme activity and sulfhydryl. The results showed that, pH was from 6.33 ± 0.005 to 7.42 ± 0.005 (p < 0.05); PV was 1.73 ± 0.31 to 7.13 ± 0.5 (mEq/kg) (p < 0.05), and TBA was from 53.3 ± 0.28 μmol MDA/kg to 207.4± 0.47 μmol MDA/kg (p < 0.05). Protease enzyme activity reduced from 0.323–0.175 U/mg protein (p < 0.05), and sulfhydryl was from 14.39–7.198 µmol/g protein (p < 0.05). Consequently, sodium acetate effectively prevents lipid and protein oxidation, extending herring meat’s life.
Species composition of Ostracoda in the Okinawa islands, and geographical distribution of the two genera \(\textit{Loxoconcha}\) and \(\textit{Xestoleberis}\) (Arthropoda: Crustacea) around Japan
Authors: Le Doan Dung , Tsukagoshi Akira
Published: August 2023

This study was conducted in the period of 2012 to 2015 in some locations of Japan. At each location, samplings were carried out on reef slopes using SCUBA diving, on reef flats, tidal beaches and river mouths during low tide. The specimens then were treated using a differential interference contrast microscope with a camera lucida (BX-50, OLYMPUS), a quick auto-coater (JFC-1500, Ion Sputtering Device), a scanning electron microscope (SEM) in the laboratory of Shizuoka University,… The result shows that total 139 species of recent ostracoda belonging to 28 families, 70 genera recorded in the Okinawa Islands, southern Japan are found. Most diversified families include Loxoconchidae (26 species - 18.7%), Xestoleberididae (17 species - 12.2%), Bairdiidae (13 species - 9.4%), Hemicytheridae (13 species - 9.4%), Leptocytheridae (8 species - 5.8%). Based on the distributional pattern of pore systems located below the eye tubercle of Loxoconcha and the types of pores on carapaces of Xestoleberis, the species groups of the two genera were divided into three groups, i.e., Groups A, B and C. Geographical distribution of three species groups was shown for each location in the present report. The geographical distribution of three species phylogenetic groups (i.e. Groups A, B and C) of the two genera Loxoconcha and Xestoleberis suggests that the fauna of two genera in the Okinawa islands are more similar to southern faunas (e.g., Vietnam, Philippines, Australia,…) than Japanese Island Arc fauna. Hence, the origin of two genera Loxoconcha and Xestoleberis in the Okinawa islands, southern Japan may be from the South.

This study is to evaluate the precision of some new global Earth Gravitational Models in the East Vietnam Sea, selecting the best model. The method and the program for calculating Free air gravity anomaly from the global earth gravitational model have been researched and developed. Evaluation of the precision of the models is done by comparing the models with ship-derived gravity anomalies. Data with anomalous signs are detected and removed when the deviation exceeds three times the root mean square deviation. The six global earth gravitational models were evaluated in the experimental section: EGM2008, EIGEN6-C4, GECO, SGG-UGM-1, XGM2019E, and SGG-UGM-2. The evaluation results show that: in the East Vietnam Sea, when compared with 35855 points of shipborne data, the above models respectively have standard deviations of: ±6.046 mGal, ±7.559 mGal, ±5.781 mGal, ±5.832 mGal, ±5.448 mGal, and ±5.236 mGal; all models have mean deviations from shipborne gravity anomalies of about +5 mGal; The correlation between the models and the shipborne data is quite good; The model SGG-UGM-2 has the highest precision. The Free air gravity anomalies from this model have also been calculated over the territorial waters of Vietnam in the form of a grid with a mesh size of 1' × 1'.

Published: August 2023

The fall of Communism in the Central and Eastern European countries in the year 1989, was a historical change had occurred after the demise of communism. The decline of the Berlin Wall in November 1989 was one of the most important proceedings of the period: the conclusive end of the Cold War and the Iron Curtain. After the disintegration of the former USSR, the Eastern bloc had started the modernisation of institutions and adopted the norms of democracy. The third wave of democratisation of Samuel P. Huntington’s theory would apply the democratic changes in Central and Eastern Europe and Romania as well. It traces the discussions and opinions of institutional and political development in Romania with special attention to the events around 1989 Post-communism and Eastern enlargement of the European Union. The paper assesses the role of the European Union to promote democratization through Eastern neighbour policy. The paper broadly discusses the institutional and political development in Romania and the role of Copenhagen criteria and the country’s accession to the EU in early 2007. The result of this article is that Romania has successfully integrated into the European Union but that democratization is declining in the country.

Published: August 2023

The article considers the problem of specificity of cultural memory shared by different generations of the Kaliningrad region's residents. The article is based on the results of the sociological survey of the residents carried out in 2022. Identification of specific features of perception of subjects of national (country-wide) and regional history allows to draw a conclusion about the typicality (or atypicality) of historical representations of young people and other age groups. The authors analyze the respondents' answers to the questions concerning significant historical events, the collapse of the USSR, attitude to current problems of the region's past, etc. The researchers come to a conclusion about the closeness of Kaliningrad residents' historical perceptions to those typical of Russian society as a whole, as well as about the specificity of the cultural memory of young people.

Published: August 2023

I tried to analyze ethnonational stories as important components of the modernization of post-traditional, in particular, post-Soviet societies. In the course of the study, a direct connection was established between the content of these narratives and the tasks of modernization. It is proved that the main factor in the construction of ethnically oriented stories about the past is not an individual author, but a corporation that is in complex internal and external relations of subordination and redistribution of resources. The question was raised about the "corporate" identity, which for an ethnocentric author is more important than the national identity expected of him. Qualitative differences between scientific and ethnooriented (but positioned "academic") texts are revealed. The result of the study was an attempt to develop a methodology for studying the narratives of ethnonational stories.
Laboratory and field studies to ensure the regulatory framework development and the transport facilities’ safety in the wave effect conditions
Authors: Tlyavlina Galina
Published: August 2023

This article is part of the author’s dissertation research in the field of scientific substantiation of the development and improvement of the regulatory framework for ensuring the safety of transport facilities in conditions of wave effect.

The article deals with such transport structure elements as bridge piers and railway roadbeds, which are located on the shores of the seas and are exposed to wave effects, and, as a result, need to be protected.

The relevance of the issue is due to the fact that an insufficient justification degree of design solutions for engineering protection structures can lead to environmental disasters and large financial losses. Usually, competent and strict regulation of the design process and survey work allows for avoiding large financial losses. Regulatory framework development will improve the reliability of transport facilities located in the wave effect zone. At the same time, technical regulations requirements must be substantiated by scientific research.

The article presents some results of scientific research carried out by the author to ensure the regulatory framework development and the safety of transport facilities in wave effect conditions. The following methods of scientific research were used in the work: field observations and surveys of the coastal zone and engineering protection structures of transport facilities from wave effect and physical (hydraulic) modeling.

The results of long-term field observations and surveys of the coastal zone and engineering protection structures of the railway roadbed are used: sea wall, protective wave-damping strips, groins, breakwaters, etc. at the Tuapse-Adler sections of the North Caucasian Railway and Korsakov-Nogliki of the Far Eastern Railway.

The author presents laboratory studies results of the wave protection structures operation (protective slopes, wave-damping strips with retaining structures, etc.), which were carried out by the physical (hydraulic) modeling method in wave pools and flumes.

Provides information about the regulations developed with the author’s participation based on the research. The expected efficiency from the practical application of the developed normative documents is described.

ABSTRACT BACKGROUND: Weight regain in the postoperative period after bariatric surgery is directly related to the relapse of preoperative comorbidities and a negative impact on the patients’ biochemical profile. AIMS: To assess the metabolic impact of weight regain on preoperative comorbidities and on patients’ biochemical profiles, in order to show the impact of the complications on the metabolic outcomes of bariatric surgery. METHODS: A retrospective study was carried out with 75 women in the late postoperative period of bariatric surgery who presented pathological weight regain (≥20% of the maximum weight loss). Data of interest consisted of glycemic, lipid, and inflammatory profile measurements at three different moments of evaluation: preoperative period, at the weight nadir (minimum weight), and after weight regain. A multivariate analysis was performed. RESULTS: The mean age was 46.39±12.09 years. Preoperative body mass index was 40.10±4.11 kg/m2. There was an overall increase of 3.36 points in the mean body mass index between the nadir and after regain: from 26.30±3.9 kg/m2 to 29.66±4.66 kg/m2. The mean time to reach the nadir was 18±7.6 months, with an average percentage of excess weight loss of 91.08±11.8%. The median time for pathological weight regain was 48 months, and the mean regain amongst the sample was 8.85±5.65 kg. There was a significant correlation between pathological weight regain and levels of insulin (r=0.351; p<0.011), C-peptide (r=0.303; p<0.011), C-reactive protein (r=0.402; p<0.001), and vitamin D (r=-0.435; p<0.001), the last two being the most influenced by the percentage of weight regained. CONCLUSIONS: The pathological weight regain in the postoperative period of bariatric surgery results in losses in the patients’ metabolic and inflammatory profiles. However, the biochemical benefits are sustained up to the preoperative levels of the parameters analyzed.

Abstract The present study aimed to adapt the Learned Helplessness Scale (LHS) to Brazilian Portuguese and assess its psychometric properties and nomological network in a Brazilian sample. Participants completed an online survey that consisted of the LHS, Rosenberg’s Self-Esteem Scale, and the Perceived Stress Scale. 429 people participated, aged 18-79, mostly women, from multiple regions of Brazil and socioeconomic status. Exploratory and Confirmatory Factor Analysis suggested a unidimensional solution with 18 items as appropriate. Correlations between the LHS and the other instruments also provided evidence of the expected nomological relationships. And we assessed the differences in LHS scores by sociodemographic data. These findings are favorable to the use of this instrument in Brazilian samples.

Abstract Logging and agricultural exploitation have led to the degradation of Araucaria Forest remnants and the alteration of its last preserved patches. This forest typology contains many endangered plant species, as is the case of the tree Oreopanax fulvus Marchal. To support conservation of this species and understand how different landscape matrices can influence its populations, we evaluated the demographic structure and spatial distribution of O. fulvus in two Araucaria Forest remnants in Paraná state. We delimited two plots (urban and rural population), each with 1 ha, subdivided them into 100 subplots (10 x 10 m), and recorded diameter at ground level (DGL), height, and coordinates of two post-germinative developmental stage of individuals. In each subplot, we measured slope, luminosity, and canopy height. We used Ripley’s K function analysis to describe distribution patterns of the species and the spatial relationship between mature and juvenile trees. We performed correlations between abundance and environmental and structural variables of the O. fulvus populations. Abundance varied between remnants, from 183 individuals/ha (12 mature and 171 juvenile) to 1306 individuals/ha (10 and 1296). The remnants varied in abundance and plant frequency. The species showed an investment in seedling banks. Most juvenile had DGL up to 3.0 cm and height up to 1.0 m and presented aggregated spatial distribution, while adults had random distribution. In the rural population juvenile abundance were correlated with canopy height (positively) and distance to mature trees (negatively). The slope was correlated for both sites, but oppositely, indicating that other factors might have interfered in the regeneration abundance. The urban remnant showed a high abundance of this endangered species, calling attention for potential studies in urban arborization, management and conservation of these remnants.

Published: August 2023

Abstract Rice (Oryza L.) is an essential food for more than 50 percent of the world's population and is the world's second-largest grain crop. Pigmented rice comes in various colors, such as black, red, brown, and green. Anthocyanins, like cyanidin-3-O-glucoside and peonidin-3-O-glucoside, are the primary color pigments in colored rice, whereas proanthocyanidins and flavan-3-ol oligosaccharides, with catechins as the central synthesis unit, are found in brown rice. This review article's aim is to give information and a summary of rice activities, research methods, also mechanisms of action (Oryza L.). Intake of pigmented rice was already associated with a number of health benefits, including antioxidant activity, anticancer, antitumor, antidiabetic activity, and a reduced risk of cardiovascular disease. Rice contains several bioactive compounds, such as γ-oryzanol, phenolic acid, anthocyanins, proanthocyanidins, flavonoids, carotenoids, and phytosterols, which have been widely studied and shown to have several pharmacological activities. The use of current herbal compounds is rapidly increasing, including the practice of pharmacological disease prevention and treatment. Herbal remedies have entered the international market as a result of research into plant biopharmaceuticals and nutraceuticals. Through a variety of pharmacological activities, it is clear that Oryza L. is a popular herb. As a result, additional research on Oryza L. can be conducted to investigate more recent and comprehensive pharmacological effectiveness, to provide information and an overview of Rice (Oryza L.) activities, research methods, and mechanisms of action. Several natural substances are characterized by low water solubility, low stability, and sensitivity to light and oxygen, and the potential for poor absorption of the active substances requires modification of the formulation. To improve the effectiveness of pharmacologically active substances originating from natural ingredients, drug delivery systems that use lipid-based formulations can be considered innovations.

Abstract Aquatic macroinvertebrates are integral parts of functioning wetlands, inhabiting a diversity of aquatic ecosystems where communities are spatially structured. Macroinvertebrates of some Mediterranean regions such as North Africa are still not well studied. Here, we study the community structure of benthic macroinvertebrates in four different types of lotic and lentic wetlands in the semiarid Haut Plateaux of Northeast Algeria. Macroinvertebrates and 06 physicochemical parameters were sampled in 12 sites belonging to four types of habitats (lotic river, lentic river, dams, and sebkha [saline lentic water body]) during January-December 2021. Eventually, the character lentic-lotic was the most important variable affecting the affecting invertebrate communities in the Mediterranean region. The results revealed that sebkha and dams had a lower Shannon index than lentic and lotic rivers. Non-metric multidimensional scaling analysis showed a strong overlap between the community composition in lotic and lentic sites . Howeverin the three types of aquatic groups lentic river, dam and lotic habitats showed a strong overlap between the community whereas sebkha was markedly separated. Redundancy analysis showed that water velocity and pH, were the main drivers of community structure of macroinvertebrates, revealed a strong effect with pH (F1,8=4.15, P = 0.001) and water velocity (F1,8= 3.22, P = 0.002) , separating lotic communities from those that inhabited dams, lentic rivers, and sebkhas. As conclusion, this study contributes to the better understanding of the community structure of macroinvertebrates in semiarid North Africa where wetlands have been experiencing high anthropogenic disturbance.

Abstract An experiment was performed to investigate the effect of mycorrhizal symbiosis and foliar application of salicylic acid on quantitative and qualitative traits of maize during 2018 and 2019 in the research farm of Islamic Azad University, Chalous Branch. Split plot in a randomized complete block design with three replications was used. Experimental factors included mycorrhiza species of (G. mosseae), (G. geosporum) and (G. intraradices) at two levels (no consumption and consumption of mycorrhiza) and salicylic acid at two levels (no consumption and consumption of 1 mμ of salicylic acid). Results of interaction effects of mycorrhiza and salicylic acid on the measured traits revealed that the maximum 1000-grain weight, grain yield, biological yield, phosphorus, potassium, nitrogen percentage and yield of maize grain protein were observed in G. mosseae treatment under foliar application of salicylic acid. Foliar application of salicylic acid increases the root length and provides the necessary conditions for increasing water and nutrient uptake alongwith increase in photosynthesis and thus allocates more photosynthetic substance for development of reproductive organs. Hence, it increases maize grain weight and accordingly grain yield. In general, the results revealed that mycorrhiza and foliar application of salicylic acid increase growth indicators, yield and yield components. It also improved the quality traits of the maize plant. Based on results, the interaction effect of G. mosseae treatment and foliar application of salicylic acid yielded better results than other treatments. Mycorrhiza increases the number of grain in the ear, the number of rows in the ear, increases the plant's ability to absorb phosphorus, and the increase of mycorrhiza along with salicylic acid shows the maximum grain yield in maize. Finally, it can be concluded that the use of mycorrhiza and salicylic acid can be effective in increasing grain in the plant.

RESUMO Objetivo: Esta pesquisa objetivou delinear os perfis de comprometimento organizacional (PCO) de diferentes trabalhadores do serviço público, em duas universidades federais, tomando como base o modelo tridimensional de Meyer e Allen (1991), e discutir características socio-demográficas e ocupacionais associadas a tais perfis. Originalidade/valor: Os resultados permitiram a emergência de novos PCO no cenário de pesquisa brasileiro sobre comprometimento organizacional (CO), assim como discussões que abordam as implicações de tais perfis, considerando o cenário do setor público e das instituições de ensino superior (IES) públicas. Design/metodologia/abordagem: Trata-se de uma pesquisa quantitativa, descritiva e de campo. O campo de pesquisa foi constituído por 470 respondentes de três categorias ocupacionais distintas: servidores técnicos, gestores e terceirizados, atuantes em áreas administrativas de duas universidades federais do Nordeste. Utilizaram-se as seguintes técnicas: análise fatorial exploratória e análise de perfis latentes. Resultados: Considerando a estrutura fatorial da escala de CO (dimensões afetiva, normativa e de continuação), foram delineados quatro PCO: descomprometidos; comprometidos de combinação afetivo-continuação; moderados; e comprometidos afetivamente. Os trabalhadores com menor tempo de serviço e do gênero masculino predominaram entre os descomprometidos. Os servidores técnicos e os terceirizados predominaram entre os comprometidos de combinação afetivo-continuação e os comprometidos afetivamente, enquanto os gestores concentraram-se entre os comprometidos de combinação afetivo-continuação.

ABSTRACT Objective: The aim of this study was to assess the prevalence of COVID-19 misinformation among migrants aged 50 or older residing in Brazil and Portugal. Method: This was a cross-sectional analytical study conducted among migrants from Portuguese-speaking countries living in Brazil and Portugal, who were 50 years of age or older. The prevalence ratios (PR) were estimated using the Poisson regression model. Results: Out of the 304 participants included in the study, 188 (61.8%) agreed with at least one piece of misinformation. Factors such as having a religious affiliation (aPR: 1.24), higher educational attainment (aPR: 1.17), knowing someone who died from COVID-19 (aPR: 1.78), and having no intention to get vaccinated (aPR: 1.36) were associated with a higher likelihood of agreeing with COVID-19 misinformation. Conclusion: The findings suggest that access to misinformation was influenced by social, economic, and religious factors among elderly migrants with low digital literacy, thus contributing to the dissemination of false content within this population.

RESUMO Objetivo: Avaliar os conteúdos de desinformação relacionados a COVID-19 entre migrantes com 50 ou mais anos de idade residentes no Brasil e em Portugal. Método: Estudo transversal e analítico, com migrantes de países falantes do português residentes no Brasil e em Portugal que possuíam 50 anos ou mais de idade. O modelo de regressão de Poisson foi utilizado para estimar as razões de prevalência (RP). Resultados: Dos 304 participantes deste estudo, 188 (61,8%) concordaram com ao menos um conteúdo de desinformação. Ter uma religião (aPR:1,24), maior escolaridade (aPR:1,17), conhecer alguém que morreu decorrente da COVID-19 (aPR:1,78) e não pretender se vacinar (aPR:1,36) influenciaram a concordância com a desinformação da COVID-19. Conclusão: O acesso às desinformações esteve relacionado com aspectos sociais, econômicos e religiosos dos envolvidos e contribuíram para que a população idosa migratória de baixo letramento digital, pulverizasse conteúdos falsos entre outras pessoas.

Resumo Reflexos do Império na educação portuguesa (1906 a 1951). Desbravando um campo pouco explorado aborda a questão da imagem das colónias e do colonizado no contexto da educação portuguesa (1906 a 1951), através de manuais escolares portugueses, em que um manual foi editado para ensinar crianças angolanas indígenas. Este último foi editado em dois momentos – supõe-se que no início da República, e em sucessivas reedições, durante a Ditadura. Recorrereu-se a materiais referentes à 1ª exposição colonial de 1934 e à exposição do Mundo Português 1940. O trabalho situa-se na perspetiva dos estudos pós-coloniais, no que procura fazer uma releitura do colonialismo na educação portuguesa. Foram usadas fontes heterogéneas, e o trabalho representa apenas um levantar de questões a apontar o muito que há a estudar.

Published: August 2023

Resumo Este artigo trata dos impactos que a nova forma de organização do processo de produção, com utilização das novas tecnologias, tem sobre o tempo de trabalho, particularmente os impactos no tempo de trabalho dos trabalhadores em plataformas digitais. Para tanto, discorre rapidamente sobre as antigas formas de organização do processo de produção e analisa a composição do tempo do trabalhador. Em seguida, analisa os impactos que a nova gestão da força de trabalho com o controle algorítmico e a gameficação tem sobre as três dimensões do tempo de trabalho: extensão, intensidade e distribuição. O estudo conclui que as novas técnicas de gestão têm forte impacto sobre as três dimensões do tempo de trabalho: aumentam a extensão do tempo de trabalho, intensificam o ritmo e alteram a distribuição, tornando a força de trabalho disponível durante sete dias na semana e 24 horas por dia.

Authors: Cavinato Nayara Regina , Capitani Daniel Henrique Dario
Published: August 2023

Resumo Este trabalho objetiva analisar a eficiência social das cooperativas de crédito rural no Brasil. Especificamente, propõe-se avaliar a influência de fatores regionais sobre a eficiência destas instituições. A análise é conduzida a partir de um modelo de programação linear não paramétrico da análise envoltória de dados (DEA) com retornos variáveis de escala e orientado a output, aplicado a 261 cooperativas de crédito rural no período de 2012 a 2017. Em geral, observa-se uma baixa frequência de cooperativas socialmente eficientes, entre 30% a 35%, predominantes nas regiões Sul e Nordeste. No Nordeste, observa-se uma prevalência de cooperativas de porte micro, mostrando o potencial contributivo destas instituições para o desenvolvimento regional. Na região Sul, as cooperativas socialmente eficientes são de maior porte e tendem a se localizar em áreas com maior concorrência e cuja atividade agropecuária é mais dinâmica e tradicionalmente presente, evidenciando seu importante papel no desenvolvimento da agropecuária local.
Inteligência Artificial, ChatGPT e Estudos Organizacionais

Resumo O avanço da utilização das Inteligências Artificiais (IAs) no campo científico, a exemplo de Connected Papers e ChatGPT, tem nos possibilitado refletir sobre como ferramentas tecnológicas se tornaram mediadores e participantes no contexto da educação e da academia. No campo das teorias organizacionais, a despeito das diferentes perspectivas de compreensão da incorporação das IAs na prática acadêmica, destacamos dois desafios em nosso cotidiano acadêmico. O primeiro desafio refere-se ao enfrentamento do colonialismo digital que as IAs nos impõem, considerando que elas se constituem por meio da reprodução de modelos de linguagem programados em países do “Norte global”. O segundo desafio diz respeito aos seus desdobramentos no processo de automatização da escrita acadêmica em administração. Consideramos a necessidade de se refletir como os usos das IAs podem reproduzir contemporaneamente nosso lugar no campo da ciência como o de extrativismo de dados científicos, a limitação do ensino da escrita acadêmica em administração como sendo a reprodução de uma “programação assistida” de modelos de linguagens hegemônicos e as possibilidades de desenquadrar como forma de contrapor essa dinâmica de automatização da escrita de artigos em administração.
