Infedeltà nel trasferimento delle collocazioni nella traduzione dei romanzi di Michel Houellebecq dal francese all’italiano
Authors:   Uniwersytet Śląski w Katowicach/Université Sorbonne Paris Nord, Polonia / Francia, Golda Paweł
Published: September 2024

Building on my PhD project, this paper explores fidelity challenges in the transfer of verb-nominal collocations (VNC) in the Italian translations of seven of Michel Houellebecq’s novels. I examine various kinds of infidelity, such as omissions, errors, incongruence in constituent transmission, incoherence in recurrent VNC transmission, and infidelity at the level of phraseological coverage. The accurate transfer of collocations is crucial for preserving the style and the vibrancy of the source text. Errors, omissions, and unjustified transformations in the target language speak to the complexity of the translation process. My analysis explains the multifaceted nature of collocations and contributes to a nuanced understanding of their role in literary translation.

Resumen: El objetivo del estudio fue estimar la prevalencia de malnutrición por indicadores antropométricos agrupados y describir los factores sociodemográficos, alimentarios y condiciones de salud determinantes de malnutrición en personas mayores colombianas. Se realizó un análisis secundario del estudio Salud, Bienestar y Envejecimiento (SABE) Colombia, 2015. Incluyó 23.694 personas ≥ 60 años. La malnutrición por exceso se definió agrupando dos indicadores: índice de masa corporal (IMC) y circunferencia de cintura; el déficit de peso se definió agrupando el IMC y las circunferencias de brazo y pantorrilla. Para asociar la malnutrición con variables sociodemográficas, alimentarias y condiciones de salud se usó la prueba chi-cuadrado y para determinar la heterogeneidad de la malnutrición se realizó un análisis de clases latentes. El exceso de peso fue 31,9%; mientras que el déficit de peso según IMC y circunferencia de pantorrilla fue 7,9%, e incrementó a 18,8%, al tener en cuenta además la circunferencia del brazo. Se generaron cinco clases latentes para malnutrición, clase 1: sin exceso de peso y con deterioro en condiciones de salud; clase 2: sin déficit de peso y con deterioro en condiciones de salud; clase 3: sin malnutrición ni deterioro en condiciones de salud; clase 4: exceso de peso y multimorbilidad, y clase 5: bajo consumo de alimentos proteicos sin déficit ni exceso de peso. Se concluye que existe una prevalencia de malnutrición elevada en las personas mayores, representando más el exceso que el déficit. Tanto los factores sociodemográficos, alimentarios y condiciones de salud, se asocian de forma diferente al exceso que al déficit de peso.

Objetivo: descrever as curvas epidêmicas e analisar o perfil epidemiológico dos pacientes hospitalizados pela COVID-19 em um município de tríplice fronteira. Método: descritivo-quantitativo. A população configurou-se de casos de COVID-19 que necessitaram de hospitalização, analisando variáveis como: idade, sexo, raça/cor, município de residência, ocupação, gestante, paciente institucionalizado e evolução. Utilizou-se a análise estatística descritiva e os testes análise de variância e qui-quadrado. Resultados: identificaram-se quatro curvas epidêmicas no período estudado. Dentre os casos hospitalizados, predominou o sexo masculino (55%). A cura foi o desfecho mais frequente nas curvas 1, 2 e 4, porém sem diferença estatística (p = 0,2916). A curva 3 apresentou uma maior frequência de óbitos (41,70%) em relação à cura (38,77%). As médias de idade foram significativamente diferentes entre as curvas, sendo que a curva 4 apresentou a menor média de idade. Conclusão: concluiu-se que as curvas epidêmicas foram influenciadas por diferentes situações; população não vacinada, flexibilização das medidas restritivas, reabertura da fronteira Brasil-Paraguai, interrupção das ações de controle, aglomeração de pessoas e circulação de novas variantes. Por meio do perfil epidemiológico dos doentes hospitalizados, concluiu-se que ser do sexo masculino, de raça/cor parda, na faixa etária de 61 a 85 anos, estar privado de liberdade se associaram com a hospitalização e ocorrência de óbito.

Objective: to map the competencies of aerospace nurses in disaster situations. Method: a scoping review following the steps recommended by the JBI and the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist. The review was conducted in three phases by two independent reviewers, with blinding, and supported by a third reviewer to resolve disagreements. Selection was based on the analysis of titles, descriptors, and abstracts, with specific eligibility criteria, followed by the full-text reading. At the end of the selection phase, 37 publications were included. Results: the results highlighted the need for the development of technical skills, knowledge of flight physiology, familiarity with aeronautical emergency procedures, communication skills, leadership, and responsibilities in aircraft preparation. During transport, nurses perform patient history taking (anamnesis), physical examinations, patient monitoring, clinical procedures, and manage in-flight complications. After the flight, they conduct documentation, develop procedures, sanitize clinical equipment, and replenish consumable materials. Conclusion: given the complexity of aerospace nursing practices in disaster situations, it is essential for professionals to develop competencies to ensure safe and effective care. There is a need to develop technologies, regulatory frameworks, and legal provisions for legal support, as well as future studies to validate and deepen the mapped competencies.

Abstract Euphorbia resinifera O. Berg is a prickly, leafless and succulent, Moroccan endemic shrub. Field data indicate that the plant faces many challenges related to its natural regeneration and its gradual decline that can lead to a probability of extinction, at least in some areas. Successful seed germination and survival of E. resinifera seedlings during the dry period is one of the main obstacles encountered in establishing natural seedlings. With this in mind, 3080 seeds of two morphotypes of E. resinifera (M1 and M2) were harvested in the Atlas of Beni Mellal to study their germinative potential and determine suitable conditions for growth and development of the seedlings. In the laboratory, five temperatures (10 °, 15 °C, 18 °C, 25 °C, and 35 °C) and two photoperiods (12 h light/12 h dark and 24 h dark) were tested. Whereas in field research, two factors were considered: the availability of water and the type of substrate (clay, peat, and limestone). Results show a maximum germination rate of around 52% for M2 at 15 °C and 48% for M1 at 18 °C. The Monitoring of plant seedling establishment and growth revealed a high vulnerability to prolonged periods of drought. However, consolidated soil is more conducive to seedling establishment. For this species, it is therefore essential to conserve the habitat within the karst geosystem. Furthermore, the variability of this species' morphotypes and their growth form architecture shows a tendency to favor the dwarf, cushion-shaped morphotype, which is the most widespread in the study area.
Understanding the habitat selection and natural history of the spider Deinopis cf. cylindracea (Deinopidae)
Authors: Villanueva-Bonilla G. A. , Stefani V. , Ponte R. P. da , Vasconcellos-Neto J.
Published: September 2024

Abstract Habitat choice is fundamental for an animal foraging, defense, and reproduction. Ogre-faced spiders are known for their unusual morphology, natural history, and rarity. They are sit-and-wait predators that build net-like webs that are manipulated by spiders and thrown at their prey. Hunting behavior includes selecting microhabitats for web construction that reduces the likelihood of damage or entanglement in the substrate during prey capture. Therefore, we expect that Deinopis cf. cylindracea selects smooth surfaces to forage on. We observed D. cf. cylindracea associated with smooth trunks of Plinia cauliflora (Myrtaceae) in the natural environment and actively selecting smooth trunks over rough trunks or litter in controlled experiments. Such selection is likely to maximize the foraging strategy of launching the web towards the substrate. Aggregations had occurred more often in the 50 cm trunk closest to the ground, where the prey community is largest. During the day, this spider appears to choose sites where it can adopt a stick-like posture upon the vegetation near the ground. Hunting at night and resting cryptically during the day appears to be shaped by natural selection for the survival and reproduction of this spider species.

Published: September 2024

O presente artigo visa dar uma resposta à seguinte questão: por que algumas Terras Indígenas são demarcadas enquanto outras não? Primeiramente, arrolamos as variáveis institucionais e não institucionais sugeridas pela literatura especializada que podem influenciar o processo demarcatório. Em seguida, aplicamos a técnica de Qualitative Comparative Analysis (QCA) sobre um crisp set composto por 40 casos de Terras Indígenas em diversas regiões do país. Demonstramos que: 1) a coesão intragrupal das lideranças indígenas, em conjunção com atos de mobilização e protesto indígena, respondem pela maioria dos casos de demarcação verificados; e 2) possibilidade de obtenção da demarcação por uma via composta por fatores puramente burocráticos. Concluímos apontando para a importância de que o Estado brasileiro, no tratamento com os distintos grupos indígenas do país, não atue para agravar suas possíveis divisões internas, sob pena de neutralizar um fator crucial para a garantia dos direitos territoriais desse segmento populacional.
Evaluating momentum in Brazil using quantile regressions
Authors: Silva Rodrigo Abbade da , Costa Jr. Newton da , Armada Manuel J. da Rocha
Published: September 2024

Abstract The purpose of this study was to measure the relationship between expected returns and capital gains overhang (CGO) (a proxy for the disposition effect) in the Brazilian financial market. It also investigated the ability of the disposition effect to induce momentum. Quantile regression allows the study of the importance of extreme values in the regression. In this way, it is possible to study the relationship between the disposition effect and the expected return between losing and winning stocks using data for the Brazilian financial market. This may help explain the conflicting results found in the literature when studying this relationship in other countries. This study contributes to the development of the topic of the relationship between the disposition effect and unrealized capital gains in the financial market. For this, we apply Fama-MacBeth regression and quantile regression models. Initially, we study the relationship between CGO and expected return. Subsequently, we investigate the ability of the disposition effect to generate the momentum effect at extreme quantiles of expected return (0.05th - losing stocks and 0.95th - winning stocks). We used a sample of 227 shares of companies listed on the Brazilian stock exchange (B3) and monthly historical series from January 2000 to October 2018. We found a significant and positive relationship between CGO and expected return across different levels of expected return, decreasing from the lowest to the highest quantile of expected return. This indicates that Brazilian investors, who are prone to the disposition effect, operate at the extreme quantiles of expected return.

Published: September 2024

Abstract Hypostomus khimaera, described from the upper rio Paraguai basin in Brazil, was reported to present some morphological variations in its original description, which allied to its relatively wide geographical distribution reinforced the need for a new assessment of its taxonomic status. Here, we analyzed a new robust set of material, composed by 636 specimens from several localities within the upper rio Paraguai basin, besides the material listed in the original description. From this, it was possible to better understand the limits of the species providing a more accurate diagnosis and a redescription for H. khimaera, which also brought some light to the limits of the H. cochliodon group itself. The species can be distinguished from its congeners by having the following features: (I) absence of a notch between the metapterygoid and hyomandibula, (II) acutely angled dentaries, with up to about 90°, (III) teeth with medial cusp ranging from villiform to shovel-shaped, (IV) opercle completely surrounded by a thick layer of skin, (V) a longitudinal dark stripe along middle portion of flanks, which is variably diffuse, and (VI) dark spots on at least one part of the body. Although morphological and color pattern differences have been found in different populations along the upper rio Paraguai basin, all examined specimens are herein considered to belong to H. khimaera, a decision based on both morphologic and molecular analyses. Additionally, an updated identification key for the Hypostomus species in the Brazilian portion of the upper rio Paraguai basin is also provided.

Published: September 2024

ABSTRACT Objective: The aim of this study was to investigate the contextual factors associated with the quality of life (QOL) of Brazilian children aged 0–12 years during the strict period of social isolation. Methods: This observational cross-sectional study was conducted between July and September 2020 using an online questionnaire on QOL-related family factors and the Pediatric Quality of Life Inventory (PedsQL™). Results were analyzed by multinomial logistic regression analysis. Results: The sample had 849 children, mostly from the South Region of Brazil (75%), white (83%), with typical development (79%), sedentary (68%), using screen (85%) for >3 h/day (44%). Their mothers were their main caregivers (90%). The following variables were significantly associated with high scores of QOL: typical health status (OR 2.38; 95%CI 1.60–3.55; screen time ≤2 h/day (OR 1.62; 95%CI 1.17–2.24); social distancing considered as “easy” (OR 1.67; 95%CI 1.20–2.32), and stimulation of the child by the family (OR 1.93; 95%CI 1.08–3.45). Conclusions: This study indicates that the family context can influence children’s QOL, especially during the COVID-19 pandemic and home environment reorganization.
A partilha do sensível em contextos de exclusão: reflexões sobre a escrita afrofeminina na contemporaneidade
Authors: de Oliveira Valdício Almeida , Mineiro Imara Bemfica
Published: September 2024

Resumo O artigo propõe-se a refletir sobre a escrita afrofeminina com base na noção de partilha do sensível (Rancière, 1995; 2005) e avaliar seu papel como arte simbólica de resistência em contextos marcados pela colonialidade (Quijano, 2005; Lugones, 2008; Mignolo, 2017) e suas teias de hierarquias e exclusões (Grosfoguel, 2009). Lançamos mão do diálogo com autoras como Lélia Gonzalez (1982), Glória Anzaldúa (2000), Vera Soares (2000), Conceição Evaristo (2005), Angela Davis (2016), Patricia Hill Collins (2016), Grada Kilomba (2019) e Sueli Carneiro (2019), a fim de responder a seguinte questão: de que forma a escrita afrofeminina incide sobre a partilha do sensível e qual o potencial insurgente dessa incisão? Para isso, após uma introdução sobre a relações entre escrita e política propostas no conceito de partilha do sensível, organizamos a discussão em torno de cinco temas: 1. Colonialidade, hétero-hierarquia e interseccionalidade; 2. Sonhar a diferença; 3. Escrita e insurgência; 4. Incisões na partilha; e 5. Habitar as ausências. Ao final das reflexões desenvolvidas, consideramos que tal potencial descanse sobre o caráter imperativo e definitivo de reconfiguração que a escrita afrofeminina provoca na dimensão sensível da comunidade.

RESUMO Este artigo teve como objetivo analisar como os discursos oriundos da extrema-direita sobre educação são compreendidos pelos eleitores conservadores. Por meio de minigrupos focais com professores, mães e pais de estudantes da rede pública classificados como conservadores moderados, buscou-se compreender: até que ponto esses discursos são conhecidos; e qual é o grau de aderência a esses temas de um eleitor médio. Os tópicos abordados incluíram: homeschooling, militarização das escolas, entre outros. Concluiu-se que há pouca familiaridade e baixo conhecimento sobre os temas abordados, com algumas exceções. Apesar de a linguagem e de o pensamento conservador permearem os discursos de forma geral, é possível identificar nuanças e contradições nas crenças e opiniões desse público.
Artificial neural network models to support urban waste management: A technological resource that drives the achievement of Sustainable Development Goals
Authors: Thomaz Igor Pinhal Luqueci , Mahler Claudio Fernando
Published: September 2024

ABSTRACT Waste management is crucial to achieving the Sustainable Development Goals (SDGs) established by the United Nations. However, traditional on-site waste characterization techniques require specialized professionals, who are exposed to biological, chemical, and physical risks. In this sense, the use of artificial neural networks (ANN) in models for characterizing municipal solid waste has been discussed, especially after the advent of the COVID-19 pandemic. Predictions made by ANN can be carried out with little or no handling of waste, making the process faster, cleaner, and safer. However, ANN models rely on datasets often provided by third parties, so they require diligent monitoring to ensure that an updated dataset is available at the appropriate regularity. This study presented two standard ANN models that were not available due to a lack of up-to-date datasets and demonstrated that dataset interchangeability may be critical for the long-term use of ANN developed to achieve SDG. Furthermore, interchangeability led to the formulation of a hypothesis about the relevance of the variable associated with basic sanitation in the greater assertiveness of one of the models during the pandemic period, resulting in the identification of abnormal patterns relating to the disposal of textiles and sanitary papers in the years 2020 and 2021. Additionally, this study can be the starting point for the development of more sophisticated interchangeable models developed with alternative datasets, meticulously chosen to reduce the effective error of the desired predictions by reducing the amplitude of the intersection set formed by different models.
Dual-chamber microbial fuel cell with denitrifying biocathode for the treatment of cassava processing wastewater

Published: September 2024

ABSTRACT The aim of this study was to assess the feasibility of using cassava wastewater as a substrate for dual-chamber microbial fuel cells (MFCs) operating with denitrifying biocathodes. Two configurations related to the ion exchange membrane used were evaluated: one with an anion exchange membrane (MFC-A) and the other with a cation exchange membrane (MFC-C). Both bioreactors were operated in sequential batch mode. Furthermore, a low-cost platform based on Arduino technology was also proposed to enable continuous measurement and recording of voltage data from the MFCs. The highest voltage values were observed in the first days of MFC operation, with readings reaching approximately 350 mV (0.41 W·m 3) and gradually decreasing after 100 days of operation to 243 mV (0.20 W·m 3) and 125 mV (0.05 W·m 3) for the MFC-A and MFC-C, respectively (mean values for the last 20 days of operation). In both MFCs, the chemical oxygen demand reduction and nitrogen removal were over 98% after reactor stabilization, with no noticeable nitrite accumulation. The experimental results indicated superior performance when MFC was equipped with an anion exchange membrane. The results presented here demonstrate the feasibility of using cassava wastewater as a viable substrate for MFCs equipped with a denitrifying biocathode, allowing for efficient wastewater treatment and simultaneous electricity generation.
Using fruit and vegetable waste to generate hydrogen through dark fermentation

Published: September 2024

ABSTRACT Fruit and vegetable waste (FVW) are sugar-rich substrates that can result in hydrogen through dark fermentation. The success of dark fermentation depends on changing operation parameters, which vary based on the characteristics of the substrate. This study aimed to determine how FVW from a central horticultural wholesaler should be fermented to produce the maximum amount of hydrogen. The following goals were listed as determining the pre-treatment method (chemical, thermic, and acid) for brewery sludge and evaluating the fermentation of the liquid fraction of FVW in an anaerobic structured bed reactor (AnSTBR). The AnSTBR operation started with sucrose as substrate at a hydraulic retention time (HRT) of 6 h. Then, the sucrose was gradually replaced by FVW at the HRT of 6 h. The FVW was fed as the sole carbon source (5 g COD/L) at HRTs of 6, 12, and 3 h for at least 20 days on each condition. The heat treatment resulted in the highest cumulative hydrogen production and hydrogen production rate (HPR) (90 mL H2 and 6.6 mL H2/h). In the AnSTBR operation, the highest values of HPR were observed at 6 h (2094 L H2/m3 reactor.d). The attempt to decrease the HRT to 3 h caused a reduction in the HPR to 216 L H2/m3 reactor.d. It is highly encouraging the increase of the organic loading rate and the use of co-fermentation, aiming to reduce the size of the reactor and water expended on dilution by increasing substrate concentration in future studies.

ABSTRACT The reverse logistics of organic solid waste (OSW) aim to return these to the economy, seeking the recovery of organic matter and reintroduction into other productive cycles, aiming for an ecologically correct outcome. However, to achieve such results, barriers between the involved stakeholders must be overcome. In this context, this study aims to answer the following research question: What is the relative importance of barriers to the implementation of OSW reverse logistics for individual waste generators in a given territory? Therefore, the objective of this research is to verify if the barriers related to the implementation of reverse logistics of OSW for the generator stakeholder (individuals), identified in the literature, are confirmed for the reality of the city of Castanhal, Pará, as well as to rank them according to their determination for the topic using the TOPSIS tool. To do so, a survey of seven barriers in the literature was conducted, followed by a survey to confirm which barriers found in the literature are reinforced for individual waste generators in Castanhal, Pará. The results indicate that for individual waste generators, only the barrier related to the difficulty in waste separation was validated in the context of the city of Castanhal, Pará. In contrast, the affirmation regarding this barrier ranked ninth in the ranking generated from the TOPSIS method. The contributions of this study are practical and theoretical, as it reinforces the existence and importance of the tested barriers empirically, adding to the collection of studies in the area and expanding discussions on the topic. In the practical field, it validates and ranks the barriers to OSW reverse logistics, assisting in identifying difficulties and opportunities for improvement, both for public and private managers.
Effects of kaolinite and montmorillonite calcined clays on the sulfate balance, early hydration, and artificial pore solution of limestone calcined clay cements (LC3)
Authors: da Silva Micael Rubens Cardoso , Andrade Neto Jose da Silva , Walkley Brant , Kirchheim Ana Paula
Published: September 2024

This study investigated the physicochemical effects of kaolinite (CK) and montmorillonite (CM) calcined clays on the sulfate balance, early hydration, and artificial pore solution of limestone calcined clay cement (LC3). The effects of fineness, clay dissolution, and ion-adsorption capacity were evaluated by isothermal calorimetry, compressive strength, ICP-OES, and zeta potential within 72 h, respectively. Increasing the fineness of both calcined clays did not significantly affect the sulfate depletion kinetics or the compressive strength and the adsorption of Ca2+ ions onto the calcined clay’s surface is not the main factor responsible for differences in sulfate demand. The higher dissolution of ions Al in CK provided an intensified and accelerated formation of ettringite that competes for the available sulfate. We demonstrate that the chemical effects have a significant impact on the sulfate balance of LC3, revealing the lesser impact of alternative clays like montmorillonite compared to metakaolin (MK) which can minimize the problem of accelerated sulfate depletion of LC3 mixes with MK.
An investigation of the behaviour of polymer fluids in the American Petroleum Institute filter press
Authors: Mcnamara Daniel P. , Sheil Brian B. , Jefferis Stephan A. , Barker Chris , Nicholson Duncan
Published: September 2024

The American Petroleum Institute (API) filter press test has been used for decades in the construction industry as part of the quality control regime for bentonite-based excavation support fluids. The industry has carried over the use of this test to polymer fluids despite the lack of published evidence of its suitability for these fluids and the very different mechanisms by which polymer fluids and bentonite slurries achieve excavation support. This paper presents the first systematic investigation of this issue through a combination of laboratory testing and theoretical analysis. The investigation demonstrates the very different behaviours of bentonite slurries and polymer fluids. In contrast to the results for bentonite slurries, API filter press results for polymers are shown to be highly sensitive to the filter paper used. In particular, repeatability testing revealed a substantial variation in the polymer fluid loss rates attributable to three primary factors: (a) the filter paper pore size; (b) filter paper damage resulting from the applied test pressure; (c) apparent ‘clogging’ of the filter paper pore space. Furthermore, the study demonstrates the poor repeatability of the API filter press test for polymer fluids even when filter papers of the same type are used. Interestingly, analysis of polymer flow with respect to filter paper pore size and the applied pressure showed that the filter papers were behaving as porous media rather than a simple bundle of capillaries; their behaviour could not be modelled using a simple capillary bundle model. Importantly, this finding shows that the filter press may provide a rapid method of assessing the apparent viscosity of polymer fluids in porous media at high shear rates – data that cannot be obtained by rotational viscometry, and would otherwise require resort to permeameter testing of coarse soils. The investigation demonstrates that the filter press test is not useful for the on-site quality control of polymer fluids but, given the theory presented in the paper, it can be a useful laboratory tool that provides valuable insight into polymer fluid flow behaviour in soils of high hydraulic conductivity, the most challenging soils for polymer fluid support.

Drawing on the composition of shells and the microstructure of cross-laminated sheets, laser sintering technology was used to prepare laser-sintered fabrications of veined red snail powder as an inorganic material and polylactic acid (PLA) as an organic material. The process was optimized using the response surface method based on one-way experiments by adding veined red snail powder. At a 13.27 W laser power, 1.2 m/s scanning rate, 0.17 mm scanning spacing, and 0.23 mm delamination thickness, the bending strength of the veined red conch powder/PLA composite powder parts reached 8.53 ± 0.15 MPa, with an error of only 1.7% from the model’s predicted value. Under these process conditions, the characterization of laser-sintered parts with 0, 5, 10, 15, 20, and 25 wt% veined red snail powder revealed that parts with 15 wt% exhibited optimal mechanical properties, showing a 155.9% improvement over pure PLA parts.

Strategic cooperation of high tech companies of China and Russia
Authors: Alimuradov M. K. , Chen Z.
Published: September 2024

The sanctions imposed on the Russian economics in 2022 by a number of countries created an external shock for many industries in Russia with the strongest impact on the enterprises of high tech industries. At the same time, there is an emerging potential for cooperation between Russian and Chinese manufacturers which is forming new strategies of development of Russian high tech enterprises. In order to evaluate the prospects and trends of development of Chinese high tech industry in this context, the authors applied methods of economic analysis including the correlation analysis. Factors, determining potential of cooperation between Russia and China in this sphere, were systematized on the basis of the methodology of strategizing by Professor Vladimir L. Kvint.

It has been stated that Chinese manufacturers are able to replace either partially or completely European and American suppliers in a number of high tech industries: innovative components and equipment for engineering, semiconductors and chips, telecommunications equipment and components. It has been discovered that the number of registered patents and the number of researchers involved in RD in China have a significant correlation with the growth of export of high tech products of China. Further growth will be able to ensure the expansion of technology and knowledge exports from China to Russia.

Thus, it can be stated for sure that there are perspective industries and fields of Russia-China cooperation in high tech industry. The sphere of cooperation which can become the basis for the strategy of development of Russian high tech manufacturers is scientific and patent cooperation with Chinese organizations. The authors have also discovered limitations in this cooperation: there is a threat of imposing international sanctions on Chinese manufacturers; Chinese enterprises are working at a high level of workload in the context of the global economic recovery after the coronavirus pandemic; decrease of competitiveness of Russian high tech industry has a negative impact on the expected benefits from the cooperation between the countries. These strategic threats can be overcome with the help of a well-grounded foreign economic strategy developed by Russian and Chinese authorities.
The sectoral aspect of staffing for strategic development of the sphere of artificial intelligence

Published: September 2024

The resource support of any developed strategy according to the chosen priorities is one of the most important stages of its formation and implementation. The solution of this task affects the dynamics of development of the economy’s high technology industries as the objects of strategizing in the emerging digital economy. One of the priority technological vectors of development of Russia is the sphere of artificial intelligence (AI), and so there arises the problem of the resource support of this direction. The purpose of the article is to study staffing as one of the key factors of strategic development of the Russian AI sphere in the industry context. The analysis is based on the methodology of strategizing by Professor V.L. Kvint and the concept of strategic human resources management by Doctor I.V. Novikova. The calculations are based on the Russian universities’ data on the number of graduates by educational programs in the AI sphere in 2023 and their employment. During the research the authors found out the number of graduates in the AI sphere by the industry specialization of educational programs; defined the sectoral specifics of employment of the graduates specializing in the AI sphere; identified the key employment organizations and jobs. The authors made conclusions about resource support of the AI development strategy in the industry context. The results will be useful for correcting the developed strategies in the AI sphere and for predicting staffing provision with the consideration of the time lag in the staff training.
Fluvoxamine Administration Attenuates Lipopolysaccharide-Induced Pancreatic Damage
Authors: Topsakal Şenay , Özmen Özlem
Published: September 2024

Objective: Certain types of bacteria contain lipopolysaccharide (LPS), which can cause widespread inflammation in the body, including the pancreas. Fluvoxamine (FLV), a selective serotonin reuptake inhibitor (SSRI) commonly prescribed for psychiatric disorders, has been shown to possess anti-inflammatory properties and may be beneficial in conditions involving tissue damage and inflammation. This study aims to evaluate the potential protective effects of FLV against experimentally induced pancreatic disease in rats using LPS.
Material and Method: In this experiment, a total of 32 Wistar albino male rats were randomly divided into four groups: control, LPS (5 mg/kg, intraperitoneally (i.p.)), LPS + FLV (50 mg/kg FLV, i.p.) and FLV. The rats were euthanatized 6 hours after the administration of LPS, and serum and pancreas tissue samples were collected during the necropsy for biochemical, histopathological, and immunohistochemical evaluations.
Results: According to the study findings, LPS lowered blood glucose levels. Histological examination showed that LPS caused edema, mild infiltration of inflammatory cells, increased vacuolization in the cells of the Langerhans islet, and severe hyperemia. Immunohistochemical investigations revealed a reduction in the expression of insulin and amylin. The biochemical, histopathological, and immunohistochemical outcomes were improved by FLV.
Conclusion: The results of this experimental rat model study indicated that LPS causes damage to the endocrine pancreas. However, FLV demonstrated significant ameliorative effects on the pancreas in rats with LPS-induced pancreatitis.
Effects of School-Based Interventions Implemented by Nurses for Children Aged 3-6 Years: A Systematic Review of Experimental Evidence
Authors: Algül Gökçe , Kılıçarslan Ebru
Published: September 2024

Objectives: The 3-6 age period, which includes the pre-school, is when the child acquires essential habits, develops skills, and socializes. This systematic review was planned to examine the available evidence on the effectiveness of school-based interventions implemented by nurses and administered to preschool children.
Material and Method: The systematic review used a search to identify studies published between 2015 and 2024 from PubMed, Medline, Cochrane Library, ProQuest, Science Direct, and Web of Science databases.
Results: When the findings were examined, fifteen studies, including six randomized controlled trials and nine quasi-experimental studies, met the inclusion criteria. In the studies conducted, it was determined that the duration of the interventions applied only to children was between 2 and 16 sessions, the intervention periods of the studies that included parents along with children were between 8 and 30 sessions, and only 4 studies used theory or models. It was determined that the programs applied by nurses to children between the ages of 3-6 in the school environment provided children with knowledge and skills and had positive effects on the development of their physical, social, and emotional health.
Conclusions: Nurses are responsible for increasing children's knowledge and skills in schools and promoting healthy lifestyles. Nurses must collaborate with parents to ensure that children's health education at home and school complement each other. The results of the studies included in the systematic review should be cautiously interpreted due to the limited number of studies and small sample size. To obtain the best evidence on the effectiveness of interventions, randomised controlled trials aiming to improve social and emotional competencies are needed to evaluate comprehensive, high-quality, and long-term effects.
