Beyond Nation and Empire? Questioning the Role of Religious Missions under Portuguese Colonial Rule at the Turn of the Twentieth Century
Authors: Dores Hugo Gonçalves
Published: February 2024

From the beginning of European overseas expansion in the fifteenth century, religious missions occupied an important place in the internal organisation of colonial empires. Their contribution to the ideological structuring of imperialism and the interaction with local populations is undeniable. With the emergence of the new imperialism and the scramble for Africa (after the 1870s), the missions, often anticipating the colonial political and administrative presence, enhanced their role as advocates of Europe’s “civilising mission”, above all through the education of the colonised peoples. For Portuguese decision-makers, the religious missions, with a multi-century tradition, had an important role in defending territorial claims overseas and promoting the empire’s nationalisation. However, the lack of national missionaries, Christianity’s inter-confessional competition in the nineteenth century and the emergence of international legal rules protecting missionary activities hindered Portugal’s strategies. Using sources from several archives (in Lisbon, the Vatican, and elsewhere) to emphasise the role of a transnational missionary staff and the international law of missions, this text intersects these aspects, examining their convergence in the controversial case of the exit and replacement of Jesuit missionaries in Mozambique in 1910–1911, to demonstrate the need to look at the missionary issues in the Portuguese overseas domains from perspectives that go beyond nation and empire.
Long-Term and Decadal Sea-Level Trends of the Baltic Sea Using Along-Track Satellite Altimetry
Authors: Mostafavi Majid , Ellmann Artu , Delpeche-Ellmann Nicole
Published: February 2024

One of the main effects of climate change is rising sea levels, which presents challenges due to its geographically heterogenous nature. Often, contradictory results arise from examining different sources of measurement and time spans. This study addresses these issues by analysing both long-term (1995–2022) and decadal (2000–2009 and 2010–2019) sea-level trends in the Baltic Sea. Two independent sources of data, which consist of 13 tide gauge (TG) stations and multi-mission along-track satellite altimetry (SA), are utilized to calculate sea-level trends using the ordinary least-squares method. Given that the Baltic Sea is influenced by geographically varying vertical land motion (VLM), both relative sea level (RSL) and absolute sea level (ASL) trends were examined for the long-term assessment. The results for the long-term ASL show estimates for TG and SA to be 3.3 mm/yr and 3.9 mm/yr, respectively, indicating agreement between sources. Additionally, the comparison of long-term RSL ranges from −2 to 4.5 mm/yr, while ASL varies between 2 and 5.4 mm/yr, as expected due to the VLM. Spatial variation in long-term ASL trends is observed, with higher rates in the northern and eastern regions. Decadal sea-level trends show higher rates, particularly the decade 2000–2009. Comparison with other available sea-level datasets (gridded models) yields comparable results. Therefore, this study evaluates the ability of SA as a reliable source for determining reginal sea-level trends in comparison with TG data.

Published: February 2024

The gravity wave (GW) potential energy (Ep) in the lower stratosphere (LS) of the altitude range between 20 and 30 km over the Indian region (60°E–100°E, 0°–30°N) is retrieved using the dry temperature profiles from the Constellation Observing System for Meteorology Ionosphere and Climate-2 (COSMIC-2) radio occultation (RO) mission from December 2019 to November 2021. Through correlation analysis and dominance analysis (DA) methods, the impacts of multiple influencing factors on the local LS GW activity are quantified and compared. The results demonstrate that in the central and northern part of Indian region, the three factors, including the convective activity (using outgoing long-wave radiation as the proxy) mainly caused by the Indian summer monsoon, the mean zonal wind speed between 15 and 17 km, the height range where the maximum tropical easterly jet (TEJ) wind speed appears, and the mean zonal wind speed between 20 and 30 km, have the greatest impacts on the LS GW activity. In the southern part of the Indian Peninsula and over the Indian Ocean, the mean zonal wind shear between 20 and 30 km plays a dominant role in the LS GW activity, which is due to the fact that the GW energy can be attenuated by large background wind shears. It can be concluded that the LS GW activity in the Indian region is mainly influenced by the Indian summer monsoon, the TEJ, and the wind activity in the LS, while over different local areas, differences exist in which factors are the dominant ones.
Multi-Scale Acoustic Velocity Inversion Based on a Convolutional Neural Network
Authors: Li Wenda , Wu Tianqi , Liu Hong
Published: February 2024

The full waveform inversion at this stage still has many problems in the recovery of deep background velocities. Velocity modeling based on end-to-end deep learning usually lacks a generalization capability. The proposed method is a multi-scale convolutional neural network velocity inversion (Ms-CNNVI) that incorporates a multi-scale strategy into the CNN-based velocity inversion algorithm for the first time. This approach improves the accuracy of the inversion by integrating a multi-scale strategy from low-frequency to high-frequency inversion and by incorporating a smoothing strategy in the multi-scale (MS) convolutional neural network (CNN) inversion process. Furthermore, using angle-domain reverse time migration (RTM) for dataset construction in Ms-CNNVI significantly improves the inversion efficiency. Numerical tests showcase the efficacy of the suggested approach.

Authors: Luo Haitao , Zhang Jinming , Liu Xiongfei , Zhang Lili , Liu Junyi
Published: February 2024

Three-dimensional reconstruction is a key technology employed to represent virtual reality in the real world, which is valuable in computer vision. Large-scale 3D models have broad application prospects in the fields of smart cities, navigation, virtual tourism, disaster warning, and search-and-rescue missions. Unfortunately, most image-based studies currently prioritize the speed and accuracy of 3D reconstruction in indoor scenes. While there are some studies that address large-scale scenes, there has been a lack of systematic comprehensive efforts to bring together the advancements made in the field of 3D reconstruction in large-scale scenes. Hence, this paper presents a comprehensive overview of a 3D reconstruction technique that utilizes multi-view imagery from large-scale scenes. In this article, a comprehensive summary and analysis of vision-based 3D reconstruction technology for large-scale scenes are presented. The 3D reconstruction algorithms are extensively categorized into traditional and learning-based methods. Furthermore, these methods can be categorized based on whether the sensor actively illuminates objects with light sources, resulting in two categories: active and passive methods. Two active methods, namely, structured light and laser scanning, are briefly introduced. The focus then shifts to structure from motion (SfM), stereo matching, and multi-view stereo (MVS), encompassing both traditional and learning-based approaches. Additionally, a novel approach of neural-radiance-field-based 3D reconstruction is introduced. The workflow and improvements in large-scale scenes are elaborated upon. Subsequently, some well-known datasets and evaluation metrics for various 3D reconstruction tasks are introduced. Lastly, a summary of the challenges encountered in the application of 3D reconstruction technology in large-scale outdoor scenes is provided, along with predictions for future trends in development.

Published: February 2024

In recent years, the application of machine learning for virtual sensing has revolutionized the monitoring and management of information. In particular, electrochemical sensors generate large amounts of data, allowing the application of complex machine learning/AI models able to (1) reproduce the measured data and (2) predict and manage faults in the measuring sensor. In this work, data-driven models based on an autoregressive model and an artificial neural network have been identified and used to (i) evaluate sensor redundancy and (ii) predict and manage faults in the context of electrochemical sensors for the measurement of ethanol. The approach shows encouraging results in terms of both performance and sensitivity analyses, allowing for the reconstruction of the values measured by two sensors in a series of six sensors with different dopant levels and to reproduce their values after a fault.

Authors: Wajnert Dawid , Tomczuk Bronisław
Published: February 2024

This paper presents the design of and transient time simulations for a four-pole magnetic bearing with permanent magnets. The usage of permanent magnets reduces the consumption of electric energy in comparison to a traditional active magnetic bearing. Permanent magnets are installed in the yoke of the stator core to limit the cross-coupling of the magnetic flux generated by the windings. The first part of this paper presents the design of the magnetic bearing and its finite-element model, while the second part describes the field-circuit indirectly coupled finite-element model for the transient time simulation. The presented simulation model was used to calculate the transient response for the rotor lifting from the starting position, the step change in the rotor position and the change in the rotor position under an external impact force applied along the y-axis.

Published: February 2024

In the exploration of ocean resources, the submarine electric field signal plays a crucial role through marine electromagnetic methods. However, due to the field signal’s low-frequency and weak characteristics, it often encounters interference from the instrument’s own 1/f noise during its acquisition. To address this issue, we developed a low-noise amplifier for the submarine electric field signal based on chopping amplification technology. This amplifier utilizes low-temperature electronic components to adapt to the cold submarine environment and enhances its independence by incorporating a square wave generator. Additionally, we conducted simulations and experimental tests on the designed chopper amplifier circuit, evaluating the equivalent input voltage noise spectrum (EIVNS) and the frequency response within 1 mHz~100 Hz. The experimental results indicate that the amplifier designed in this study achieves sufficiently low noise 2 nV/√Hz@1 mHz, effectively amplifying the submarine electric field signal measured with the electric field sensor.

Published: February 2024

The Bio-Radar is herein presented as a non-contact radar system able to capture vital signs remotely without requiring any physical contact with the subject. In this work, the ability to use the proposed system for emotion recognition is verified by comparing its performance on identifying fear, happiness and a neutral condition, with certified measuring equipment. For this purpose, machine learning algorithms were applied to the respiratory and cardiac signals captured simultaneously by the radar and the referenced contact-based system. Following a multiclass identification strategy, one could conclude that both systems present a comparable performance, where the radar might even outperform under specific conditions. Emotion recognition is possible using a radar system, with an accuracy equal to 99.7% and an F1-score of 99.9%. Thus, we demonstrated that it is perfectly possible to use the Bio-Radar system for this purpose, which is able to be operated remotely, avoiding the subject awareness of being monitored and thus providing more authentic reactions.

Published: February 2024

This paper presents the integration of a sensing layer over interdigitated electrodes and an electronic circuit on the same flexible printed circuit board. This integration provides an effective technique to use this design as a wearable gas measuring system in a target application, exhibiting high performance, low power consumption, and being lightweight for on-site monitoring. The wearable system proves the concept of using an NFC tag combined with a chemoresistive gas sensor as a cumulative gas sensor, having the possibility of holding the data for a working day, and completely capturing the exposure of a person to NO2 concentrations. Three different types of sensors were tested, depositing the sensing layers on gold electrodes over Kapton substrate: bare graphene, graphene decorated with 5 wt.% zinc oxide nanoflowers, or nanopillars. The deposited layers were characterized using FESEM, EDX, XRD, and Raman spectroscopy to determine their crystalline structure, morphological and chemical compositions. The gas sensing performance of the sensors was analyzed against NO2 (dry and humid conditions) and other interfering species (dry conditions) to check their sensitivity and selectivity. The resultant-built wearable NFC tag system accumulates the data in a non-volatile memory every minute and has an average low power consumption of 24.9 µW in dynamic operation. Also, it can be easily attached to a work vest.
Understanding Musculoskeletal Loadings among Supermarket Checkout Counter Cashiers: A Biomechanical Analysis
Authors: Silva Tânia T. , Sousa Catarina , Colim Ana , Rodrigues Matilde A.
Published: February 2024

Work-related musculoskeletal disorders (WMSD) are highly prevalent among supermarket cashiers. These disorders are frequently related to the adoption of awkward postures and manual materials handling. This study aimed to analyze musculoskeletal loadings in supermarket cashiers, considering the handling of different products and different checkout conditions. To accomplish this, we employed an inertial motion capture system to measure full-body kinematics while simulating 19 cashier tasks. The study included five female cashiers from a supermarket in Northern Portugal, ranging in age from 19 to 61 years old. Using joint angles, material load, and muscle function as input parameters, we conducted the musculoskeletal loadings assessment using the Rapid Upper Limb Assessment (RULA) and Rapid Entire Body Assessment (REBA) methods. Results showed that RULA scores were higher for the microtasks that involved product scanning. Regarding microstasks analyzed by REBA, the replacement of paper rolls for the receipt machine at the checkout counter yields the highest scores. Based on these findings, there is a compelling need to redesign supermarket checkout workstations to alleviate the physical demands placed on cashiers and to ensure organizational sustainability.

Published: February 2024

The aim of this study was the analysis of interpolyelectrolyte complexes (IPECs) based on Eudragit® EPO and Eudragit® L100 as prospective carriers for gastroretentive drug delivery systems (GRDDS) using two model drugs: metronidazole (MZ) and acyclovir (ACR). Eudragit® EPO/L100 IPECs with different pH concentrations were characterized by different degrees of swelling in mimicking fasted stomach medium (0.1 M HCl) and saved their shape for 6 h. The microenvironmental changes in IPEC structures in acidic medium were investigated using FT-IR spectroscopy, thermal and elemental analysis. IPEC samples showed bioadhesive properties that were not significantly different from the positive control (Carbopol) in the test with the mucin compacts. The release rate of metronidazole (class I BCS) from IPEC matrices increased with the increasing degree of swelling. IPEC 1 provided 49.62 ± 6.20% and IPEC 2 reached 87.69 ± 5.15% of metronidazole release after 6 h in mimicking fasted stomach medium (0.1 M HCl). The total amount of released acyclovir (class III BCS) from IPEC 1 was 25.76 ± 5.67% and from IPEC 2 was 21.48 ± 5.00%. Release of both drugs was controlled by relaxation of polymeric chains in matrices according to the Peppas–Sahlin model. According to the received results, investigated interpolymer complexes are prospects for further evaluation as carriers for gastroretentive bioadhesive systems.

Published: February 2024

Bioethanol, as a renewable energy source, has been widely used in the energy sector, particularly in replacing traditional petroleum energy, and holds great potential. This study involves a whole life cycle assessment of bioethanol production and the co-production of high-value by-products—xylose, lignin, and steam—using three types of waste biomass: corn cobs, corn straw, and wheat straw as feedstocks by chopping, pretreatment, hydrolysis, fermentation, and distillation methods. Secondly, the benefits of three raw materials are compared for preparing bioethanol, and their impact on the environment and energy production is analyzed. The comparison indicates that corn cobs offer the best overall benefits, with a net energy balance (NEB) of 6902 MJ/Mg of ethanol and a net energy ratio (NER) of 1.30. The global warming potential (GWP) is 1.75 × 10−2, acidification potential (AP) is 1.02 × 10−2, eutrophication potential (EP) is 2.63 × 10−4, photochemical ozone creation potential (POCP) is 3.19 × 10−8, and human toxicity potential (HTP) is 1.52 × 10−4. This paper can provide a theoretical reference and data supporting the green refining of bioethanol and the high-value utilization of by-products, and broaden its application prospects.
Quality of Life in Rural Areas: A Set of Indicators for Improving Wellbeing
Authors: Beltramo Riccardo , Peira Giovanni , Pasino Giacomo , Bonadonna Alessandro
Published: February 2024

Quality of life can be generally defined as people’s satisfaction with their lives and personal wellbeing. Contemporary literature agrees that dimensions such as health, education, employment, leisure, social relations, security, environment, landscape, and cultural heritage should be considered. Tourism serves as a stimulus for rural development, and assessing residents’ and tourists’ quality of life is relevant for local administrators of a tourist destination. Given the absence of quality-of-life models for individual municipalities, the research questions were aimed at the mapping of quality-of-life frameworks and the construction of a set of quality-of-life indicators for Alagna Valsesia. This research was conducted in 2023. The results of the research showed the possibility of constructing a modular model of indicator sets aimed particularly at decision making by territorial policymakers. The limitations of the research are related to the difficulty of finding different indicators in public platforms and, in the future, we would like to build a synthetic indicator replicable in other Piedmontese and Italian municipalities.
Tri-Objective Vehicle Routing Problem to Optimize the Distribution Process of Sustainable Local E-Commerce Platforms
Authors: Pilati Francesco , Tronconi Riccardo
Published: February 2024

The dramatic growth of online shopping worldwide in the last few years generated negative consequences for local small retailers who do not adopt information technologies. Furthermore, the e-commerce sector is considered a good opportunity to develop sustainable logistic processes. To reach this goal, the proposed paper presents a mathematical model and a metaheuristic algorithm to solve a multi-objective capacitated vehicle routing problem (CVRP) distinguished by economic, green, and ethical objective functions. The proposed algorithm is a multi-objective simulated annealing (MOSA) that is implemented in a software architecture and validated with real-world instances that differ for the product type delivered and the geographic distribution of customers. The main result of each test is a tri-dimensional Pareto front, i.e., a decision-support system for practitioners in selecting the best solution according to their needs. From these fronts, it can be observed that if the economic and environmental performances slightly deteriorate by 1.6% and 4.5%, respectively, the social one improves by 19.4%. Furthermore, the developed MOSA shows that the environmental and social objective functions depend on the product dimensions and the geographic distribution of customers. Regarding the former aspect, this paper reports that, counter-intuitively, the metabolic energy consumption per driver decreases with bigger products because the number of necessary vehicles (and drivers) increases, and, thus, the workload is divided among more employees. Regarding the geographic distribution, this manuscript illustrates that, despite similar traveled distances, highly variable altitudes cause more carbon emissions compared to flat distributions. Finally, this contribution shows that delivering small goods decreases the distance that vehicles travel empty by 59%, with a consequent cost reduction of 16%.
Urban Traffic Flow Prediction Based on Bayesian Deep Learning Considering Optimal Aggregation Time Interval
Authors: Fu Fengjie , Wang Dianhai , Sun Meng , Xie Rui , Cai Zhengyi
Published: February 2024

Predicting short-term urban traffic flow is a fundamental and cost-effective strategy in traffic signal control systems. However, due to the interrupted, periodic, and stochastic characteristics of urban traffic flow influenced by signal control, there are still unresolved issues related to the selection of the optimal aggregation time interval and the quantifiable uncertainties in prediction. To tackle these challenges, this research introduces a method for predicting urban interrupted traffic flow, which is based on Bayesian deep learning and considers the optimal aggregation time interval. Specifically, this method utilizes the cross-validation mean square error (CVMSE) method to obtain the optimal aggregation time interval and to establish the relationship between the optimal aggregation time interval and the signal cycle. A Bayesian LSTM-CNN prediction model, which extends the LSTM-CNN model under the Bayesian framework to a probabilistic model to better capture the stochasticity and variation in the data, is proposed. Experimental results derived from real-world data demonstrate gathering traffic flow data based on the optimal aggregation time interval significantly enhances the prediction accuracy of the urban interrupted traffic flow model. The optimal aggregation time interval for urban interrupted traffic flow data corresponds to a multiple of the traffic signal control cycle. Comparative experiments indicate that the Bayesian LSTM-CNN prediction model outperforms the state-of-the-art prediction models.

Authors: Rauf Fawad , Wang Wanqiu , Voinea Cosmina L.
Published: February 2024

This research delves into the intricate interplay between green innovation performance (GIP), firm performance (FP), and corporate social responsibility (CSR) reporting, leveraging enterprise life stage performance as a pivotal moderator. Analyzing a robust sample of 5450 firm-year observations spanning from 2015 to 2021, this study employs OLS regressions with panel data sourced from the CSMAR and HEXUN databases to validate prevailing research hypotheses. The findings underscore the pivotal role of CSR reporting in augmenting corporate value while concurrently mitigating inadequacies within the system. Moreover, this study uncovers a nuanced relationship between CSR reporting, GIP, and FP in the context of China, revealing a significant moderation effect attributed to the enterprise life cycle. These revelations carry profound implications for CSR reporting stakeholders, including academics, practitioners, and regulators. Notably, they provide valuable insights to authorities and boards of directors concerning the growth potential of enterprises and states. A distinctive facet of this study lies in its exploration of the moderating influence of an enterprise’s life stage on the relationship between CSR reporting and GIP or FP.

Published: February 2024

While the effects of chronic exposure to microplastic particles (MPs) are extensively studied, the outcomes of a single treatment have received relatively less attention. To investigate MPs’ potential acute toxicity, including their impact on general health status (victual consumption, sensorimotor deficits, and clinical toxicity signs) and serum biochemical parameters (markers of organ/tissue function and oxidative stress indicators), we administered thoroughly characterized MPs (1.4, 35, or 125 mg/kg), generated from polyethylene terephthalate (PET) bottles, to adult male Wistar rats via oral gavage. The MPs’ short-term effects were assessed with well-established tests and methods. The results point to the absence of sensorimotor deficits and clinical toxicity signs, while levels of markers of liver, heart, and kidney function were altered in all MP groups. Decreased victual consumption and increased levels of oxidative stress indicators were evident following treatment with the two higher MP doses. Presented data indicate that examined MPs are able to initiate the development of local changes in tissues and organs within a short time frame, potentially leading to their damage and dysfunction. This study may increase the awareness of the detrimental effects of plastic contamination, as even a single exposure to MPs may provoke adverse health outcomes.

Authors: Ciechelska Agnieszka , Matel Anna , Poskrobko Tomasz , Sidorczuk-Pietraszko Edyta
Published: February 2024

The purpose of this paper was to investigate whether consumer behaviour in the second-hand clothing market causes a rebound effect, and if so, what are the reasons behind it. The study examined two potential causes: the price effect and moral licensing. A survey technique was used for data collection to study the phenomenon quantitatively. Non-parametric tests, analysis of relationships between variables and hierarchical cluster analysis were used to analyse the results. The existence of a rebound effect in the used clothing market was confirmed. At the same time, the magnitude of the substitution rate between new clothing and used clothing was estimated at 1:1.23. It was also proved that the phenomenon under study is influenced by both the price effect and moral licensing.

Die Professionalisierung von Lehrpersonen aus praxeologischer Perspektive. Professionelles Handeln als Entscheiden
Authors: Bonnet Andreas , Bakels Elena , Hericks Uwe
Published: February 2024

Insbesondere rekonstruktive Untersuchungen haben die Bedeutsamkeit impliziter Wissensbestände für die Professionalisierung von Lehrpersonen herausgearbeitet. Diese Linie der Professionsforschung untersucht mit Hilfe soziologischer Theorien und rekonstruktiver Methoden, welchen Einfluss sozialisatorisch erworbene Wissensbestände und die Strukturen der Organisation Schule auf das Handeln von Lehrpersonen haben. Im Zentrum dieses Aufsatzes stehen die praxeologisch zentralen Begriffe Habitus und Norm sowie die systemtheoretische Konzeptualisierung von (organisationalem) Handeln als Umgang mit Kontingenz durch das Treffen von Entscheidungen. Die Ausführungen werden an ersten Daten aus dem Projekt Professionalisierung von Lehrpersonen der Fächer Mathematik und Englisch (ProME) illustriert. In diesem Projekt wird untersucht, wie Lehrpersonen der Fächer Mathematik und Englisch im Spannungsfeld von Habitus, Organisations- und Identitätsnormen zu ihren alltäglichen Handlungsentscheidungen kommen.

Peer Reviews in Schulnetzwerken im Spannungsfeld zwischen Pädagogischer Professionalität und Organisation

Published: February 2024

Das Verhältnis von Pädagogischer Professionalität und Organisation stellt in der Erziehungswissenschaft ein ‚altes‘ Thema dar. Einen deutlichen Schub hat dieses Thema mit dem in den 1990er Jahren einsetzenden Schulentwicklungsdiskurs erhalten, der Schulentwicklung als Entwicklung der Einzelschule versteht. Das Verdrängen pädagogischen Denkens und Handelns wird seitdem immer wieder moniert, obwohl die Kritik an der Organisationslastigkeit von Schulentwicklung inzwischen relativiert wurde. Der vorliegende Beitrag soll empirisch fundierte Erkenntnisse zur Verhältnisbestimmung von Pädagogischer Professionalität und Organisation an reformorientierten Schulen liefern. Datenbasis bilden Rückmeldegespräche von ‚kritischen Freund:innen‘ (Lehrpersonen), die im Rahmen von Peer Reviews zwischen Schulen aufgezeichnet und inhaltsanalytisch ausgewertet wurden. Die Ergebnisse zeigen, dass Themen und Art der Rückmeldungen den Professionsinteressen der Akteur:innen gerecht werden und pädagogisches Handeln darüber hinaus konsequent als Handeln in Organisationen gedacht wird.

Published: February 2024

Im Rahmen des Projektes „Partizipative Schulentwicklung – Unterricht mit Schülerinnen und Schülern gestalten“ arbeiten Schulen im Sinne des DesignBased-Research Ansatzes gemeinsam mit Forschenden an der Weiterentwicklung von Partizipation von Schüler:innen. In Gruppendiskussionen werden die Erfahrungen mit Partizipation diskutiert, wobei die Auswertung mit Hilfe der Dokumentarischen Methode unterschiedliche Orientierungen bei den Lehrpersonen zu Tage bringt. Die gefundenen Orientierungen werden vor dem Hintergrund des Professionalisierungsdiskurses eingeordnet und diskutiert, wobei auch reflektiert wird, welchen Beitrag die methodische Annäherung mit Hilfe der rekonstruktiven Methode zum Diskurs um Professionalisierung leistet.

Implementation of Principles of a Healthy Lifestyle by Contemporary Russians
from Different Socio-Demographic Groups
Authors: Pokida Andrei N. , Zybunovskaya Natalia V.
Published: February 2024

Introduction: Despite all significant efforts taken by the government, the issue of a healthy lifestyle remains highly relevant for the Russian population.
Objective: To assess changes in behavioral practices of Russian people from various socio-demographic groups in terms of commitment to a healthy lifestyle.
Methods: The main source of empirical information was the Russian sociological survey conducted on April 17–26, 2023 in 29 regions of the Russian Federation. The sample consisted of 1,516 people aged 18 years and older who were interviewed at their place of residence. The results were compared with the findings of previous surveys of the same design.
Result: The study has demonstrated a decrease in the proportion of Russians who believe that they lead a healthy lifestyle (from 63.7 % in 2021 to 56.2 % in 2023). At the same time, only 13 % of the respondents were found to adhere to basic principles of a healthy lifestyle. Male sex, having no higher education, and low income were associated with a poor commitment to the latter. We have noted a rising trend in the prevalence of smoking among young people. In the group of 18–24-year-olds, we observed a 1.5-fold increase in the proportion of smokers over the previous year related to the growing popularity of vaping. We have also established an increase in consumption of energy drinks (from 16.6 % in 2013 to 22.8 % in 2023), especially among young people aged 18–24 (53.2 %). Only 27.2 % of the respondents under 40 having children reported regular physical activity and/or sports compared to a similar group of citizens without children (40.2 %).
Conclusion: Recommendations given based on the survey results are related to the importance of improving directions in social policy that promote commitment to a healthy lifestyle taking into account the needs of representatives of different socio-demographic groups.
