Have COVID-19 and the War in Ukraine Caused a Decline in the Value Relevance of Accounting Information? Evidence from Poland
Authors: Pilch Bartłomiej
Published: December 2024

Research background

Within the research area of value relevance (VR), the impact of macroeconomic changes is usually analysed. The influence of economic crises, such as the Asian financial crisis, global financial crisis, and COVID-19, on VR was, however, inconclusive. Moreover, it differs between individual markets.

Purpose

The aim of the paper was to analyse the impact of COVID-19 and the war in Ukraine on the value relevance with the example of Polish listed companies. VR of earnings, book values, and cash flows was taken into account in this regard.

Research methodology

Panel data models (fixed effects) were used. The focus was especially on interactions between earnings per share (EPS), book values per share (BVPS), cash flows per share (CFO), and binary variables referring to periods of COVID-19 and the war in Ukraine.

Results

VR of earnings, book values, and cash flows noted the positive impact of COVID-19. However, the war affected book values and cash flows negatively. The results obtained highlight the specificity of different crises and various markets, with the findings being only partially in line with the results of previous studies.

Novelty

So far, the impact of the war in Ukraine on VR has not been analysed. Moreover, the influence of COVID-19 on VR on the Polish market has also not been studied.
Investigating the Effects of Advancements in Information and Communication Technology and Financial Development on Tourism Growth: A Case of South Africa
Authors: Ssekitoleko Patrick , Manaliyo Jean Claude
Published: December 2024

Research background

South Africa’s tourism industry has been experiencing unstable growth in the past few decades due to different factors. Studies in different countries have documented the significance of information and communications technology (ICT), and financial development towards a country’s tourism growth. ICT and financial development may stimulate the growth of South Africa’s tourism industry.

Purpose

To investigate the extent to which ICT advancements and financial development influence tourism growth in South Africa, given that the country has relatively strong financial and ICT sectors.

Research methodology

The study used annual time-series data for the period 1989 to 2019, and the variables are financial development, ICT, and tourism growth. The data were analysed using the Autoregressive Distributed Lag (ARDL) model.

Results

The findings indicate the existence of a long-run relationship among the variables. Results for the long-run estimates show that only ICT has a positive and statistically significant effect on tourism growth. In the short-run, financial development has a positive significant effect on tourism growth, while ICT only registers a significant effect on tourism growth in the fourth lag, albeit negative. The policy implication of these results is that the South African government ought to promote financial development to ensure that money is available and accessible for investment in tourism businesses and for tourist spending. Furthermore, ICT upgrades are required by the government and tourism service providers to enhance tourism products and service accessibility for tourists from wider geographical locations.

Novelty

This study expanded the existing literature by assessing the effects of ICT and financial development on South Africa’s tourism.

Authors: Serap Vurur N. , Özdemir Letife , Özen Ercan , Grima Simon
Published: December 2024

Research background

The link between the price of polluting energy supplies and the renewable energy stock index may be intricate and subtle. Investors need to conduct thorough inquiries and analyses to completely understand the correlation between these industries.

Purpose

This study aims to explore the intricate dynamics between renewable energy stocks and conventional fossil fuel-based resources.

Research methodology

Our analysis encompasses daily data spanning from June 9, 2012, to March 31, 2023, extracted from the WilderHill New Energy Global Innovation Index (NEX), Crude Oil (WTI OIL), Coal (COAL), and Natural Gas (NGAS). Key statistical tests include the Johansen co-integration test, the fully modified ordinary least squares (FMOLS) test, and the Granger causality test.

Results

The study shows a long-term co-integration relationship between renewable energy stocks and polluting energy sources. Oil prices positively impact the renewable stock index, while coal prices negatively affect it. Natural gas prices also positively correlate with the index, and short-term relationships exist with oil prices.

Novelty

The study provides valuable insights for investors, state authorities, and policymakers on optimising ESG portfolio diversification and sustainable development policies in energy, environment, and climate. It helps stakeholders understand investor behaviour, market trends, and policy impacts, enabling effective long-term investment strategies.
The Ephemeral Term “Sustainable Development” in Current EU Policies
Authors: Zavřelová Veronika , Pelikánová Radka MacGregor
Published: December 2024

Research background

The term “sustainable development” is an omnipresent expression reaching the dimension of a command in the EU under the leadership of Ursula von der Leyen. However, this is an ephemeral term with ambiguous and contradictory meanings which is employed in a particular manner by current EU policies.

Purpose

The purpose of this study is to reconcile various approaches and consolidate the understanding of sustainable development as advanced by current EU policies.

Research methodology

A historical and conceptual review creates a foundation to prepare comparative review tables to be filled with information about current EU policies and their quotes regarding “sustainable development”, as extracted from the EU Commission Websites and EurLex. This allows for a holistic, thematic and critical analysis about the teleological meaning as well as glossing and Socratic questioning.

Results

The juxtaposition of these findings suggests that the term “sustainable development” is a semantic puzzle which is perceived by current EU policies as a call for multispectral and inherently conflicting changes to be imposed by all stakeholders in the utilitarian context.

Novelty

Six pioneering propositions with controversial features emerge and are to be verified by further multidisciplinary longitudinal studies.
Harnessing Open European Data for a Data-Driven Approach to Enhancing Decarbonization Measurement in the Built Environment
Authors: Beltrán-Velamazán Carlos , Gómez-Gil Marta , Monzón-Chavarrías Marta , Espinosa-Fernández Almudena , López-Mesa Belinda
Published: December 2024

To achieve climate neutrality by 2050, decarbonizing the building sector is crucial, as it currently contributes 36 % of greenhouse gas emissions in Europe. Monitoring decarbonization progress is essential for evaluating our trajectory towards long-term goals, facilitating informed decision-making. However, monitoring this issue is currently unfeasible due to a lack of real data. Despite challenges in data gathering, directives like Infrastructure for Spatial Information in Europe (INSPIRE) and the Energy Performance of Buildings Directive (EPBD) promote open data accessibility. To overcome this barrier, this paper suggests using georeferencing and automated cross-referencing of open building data to obtain data to monitor progress towards decarbonization effectively. This approach materializes in the proposal of a national-scale Urban Building Energy Model (UBEM) for Spain, which leverages data from Energy Performance Certificates (EPC) and potentially Digital Building Logbooks (DBL) to enhance it. The study demonstrates the considerable potential of this approach, not only in characterizing the energy performance of Spanish buildings based on location, type, and age but also in estimating energy consumption, carbon dioxide emissions, monitoring renovation progress, assessing energy savings, and identifying energy-inefficient building segments. Finally, this study compares the information obtained using the proposed model with the set of progress indicators of the EPBD recast for the new national building renovation plans, concluding that the UBEM model manages to provide data to collect 29 of the progress indicators and, when combined with a DBL, it would be able to provide 59. This framework holds promise for replication in other MS, offering valuable insights into the decarbonization of the European building stock.
La revue Hochland : un exemple de Kulturkatholizismus au fil du temps
Authors: Grand Sylvie Le
Published: December 2024

Der Begriff Kulturkatholizismus ist weniger bekannt als seine Entsprechung für den Protestantismus. Am Beispiel der Zeitschrift Hochland, die in diesem Zusammenhang oft erwähnt wird, werden die Merkmale jenes Begriffs sowie die wichtigsten Aspekte seines Entstehungskontextes untersucht. Zeitschriftsgeschichte und Begriffsentwicklung miteinander in Beziehung setzen, hat den Vorteil, die Sinnpluralität des Begriffs und die bemerkenswerte Kontinuität der Zeitschrift, die von Carl Muth 1903 gegründet und bis 1941 geleitet wurde, deutlich zu machen. Schließlich wird anhand zweier signifikanter Beispiele geprüft, inwieweit der Begriff Kulturkatholizismus und das Erbe von Hochland nach 1945 noch relevant waren: welches war einerseits der Stellenwert der Kunstbilder in der Publikation und welche Rolle spielte andererseits die Zeitschrift für einen ihrer Autoren, E.-W. Böckenförde?

La notion de Kulturkatholizismus est moins bien connue que son équivalent protestant. En s’appuyant sur le cas fourni par la revue Hochland, souvent citée en exemple à ce propos, on étudiera les traits distinctifs de cette notion et les éléments les plus déterminants de son contexte d’apparition. Croiser l’histoire de la revue et celle de la notion permettra de mettre en évidence le sens pluriel de cette dernière et la remarquable continuité de la première, fondée et dirigée par Carl Muth de 1903 à 1941. On éprouvera enfin la pertinence du terme de Kulturkatholizismus et la permanence de l’héritage de Hochland après 1945 à travers deux exemples privilégiés : la place de l’image d’art dans la publication et le rôle joué par la revue pour l’un de ses auteurs, E.-W. Böckenförde.

The concept of Kulturkatholizismus is less well known than its Protestant equivalent. Based on the case provided by the magazine Hochland, often cited as an example in this respect, we will study the distinctive features of this word and the most decisive factors in its emergence. Combining the history of the journal with that of the concept highlights the plural meaning of the latter and the remarkable continuity of the former, founded and directed by Carl Muth from 1903 to 1941. Finally, we will test the relevance of the term Kulturkatholizismus and the permanence of Hochland’s legacy after 1945 through two key examples: the place of the art image in the publication and the role played by the journal for one of its authors, E.-W. Böckenförde.

Yield Curve Estimation Based on Government Security Prices in the Croatian Financial Market
Authors: Orlović Zrinka , Zoričić Davor , Golubić Zrinka Lovretin
Published: December 2024

This article investigates the estimation of the yield curve based on government security prices using the Nelson-Siegel model in the Croatian financial market. The yield curve was estimated for samples of government securities with and without currency clauses. Since the Croatian financial market is less developed characterized by limited trading activity in government bonds, Treasury bills were also included in the analysis. To examine the difference in the estimation of yield curve parameters between a less developed and a developed market, the U.S. sample was considered. The yield curve was estimated for the full US sample and for artificially created U.S. samples corresponding to the Croatian samples of government bonds with and without currency clauses. Despite the less developed Croatian financial market, it is possible to estimate the yield curve and derive meaningful economic interpretations from the estimates.
Does Trade Facilitation Matter for Human Development in Lower-Middle-Income Countries?
Authors: Khaldi Khalifa , Abdelaoui Okba , Mekhzoumi Lotfi
Published: December 2024

This study aims to examine the impact of trade facilitation measures on human development in lower-middle-income countries. For this purpose, we employ panel data analysis for the 2007-2019. We estimate the relationship using four models: feasible generalized least squares, incorrect generalized least squares, panel-corrected standard errors, and Driscoll-Kraay. Our findings demonstrate that trade facilitation measures, particularly those related to port infrastructure quality and maritime transport efficiency, significantly contribute to human development in lower-middle-income countries. Based on these results, we recommend that the governments of these countries should prioritize implementing these measures, particularly those that enhance the port and maritime transport sector as a promising strategy to achieve human development.
Individual Values and Job Satisfaction as Work Engagement Predictors: Example from Croatia
Authors: Bakotić Danica , Alvir Antonela
Published: December 2024

This paper examines the relationship between work engagement, employees’ individual values, and job satisfaction. Specifically, it explores if job satisfaction and individual values can be considered as predictors of employees’ engagement at work. The empirical research was carried out in 2023, involving a sample of 277 Croatian employees. The research hypotheses were tested using hierarchical regression analysis. Statistical analysis revealed that job satisfaction is the most significant predictor of work engagement. The findings suggested that individual values influence employee work engagement, but not all values contribute equally. Among the ten observed individual values, universalism, power, benevolence, and achievement were confirmed as statistically significant predictors of work engagement. Research results suggested that management should prioritize job satisfaction to improve employee engagement. In their attempts to enhance work engagement, management should also pay attention to employees’ individual values since some have been confirmed as the determinant of work engagement.
Brief commentaries on disciplinary sanctions, with emphasis on the written warning. elements of comparative law
Authors: MARICA Mihaela Emilia
Published: December 2024

Since the field of work discipline is complex both in terms of legislation and case law, this article reviews the disciplinary sanctions provided for in the Labour Code, with a focus on the doctrinal and case law issues identified in the case of written warnings, as the simplest of the disciplinary measures that may be imposed by the employer. In addition, in order to provide a clearer technical and legislative overview of the institutions relating to disciplinary sanctions, the regulations of other countries are also relevant to this objective, and comparative law elements will be closely examined. Thus, the legal systems of Bulgaria, the United Kingdom, Israel, Switzerland, and Belgium are considered. Most of the legal systems analysed divide disciplinary sanctions into different types, which highlights quite different patterns of disciplinary sanctioning even if the determining factors of employee disciplinary liability are similar.

Authors: Alsafwani Afnan , Almarzooq Doha , Alsafwani Eman , Doumani Mazen
Published: December 2024

Background: Caries lesions had a tremendous impact on the global clinical burden. It can have deleterious effects on the patient's general wellbeing and oral care. Accordingly, appropriate diagnosis and management of caries lesions can improve clinical outcomes. These clinical outcomes depend mainly on the timing and rationale of the dentist's decision on the patient's treatment. This study aims to assess Saudi dentists' restorative treatment decisions on approximal caries lesions, including treatment threshold and restorative methods and materials.
Methods: This is a cross-sectional survey study that included dentists of different specialists working in Saudi Arabia. We collected demographic and professional information about the dentists, in addition to a case simulation to evaluate their decisions on diagnosis and management of patients. Descriptive and comparative analysis was done using Statistical Package for the Social Sciences version 26.
Results: A total of 104 Saudi dentists participated in this survey, 69.2% male, and 42.3% were aged between 26 and 30 years old. As for professional information, 76.9% of the dentists received education inside Saudi Arabia, and only 2.9% were restorative specialists. Also, 47.1% had between 2 and 5 years of experience, 81.7% worked in the governmental sector, and 69.2% practiced in an urban area. As for diagnosis and management decisions, 61.5% would use fluoride, 61.5% decided that the inner half of dentin would require immediate restorative treatment, 80.8% would use Bitewing X-ray for the detection of interproximal caries, 34.6% decided to use tunnel preparation for the smallest lesion, 55.8% would use Tofflemire band to achieve tight proximal contact, and 60.6% would use composite restorative material for the smallest approximal lesion. Also, dentists aging between 20 and 25 (p-value < 0.001), education inside Saudi Arabia (p-value = 0.002), having a restorative specialty (p-value = 0.04), more years of experience (p-value = 0.018), and working in private sector (p-value = 0.002) significantly preferred the use of fluoride for management of caries lesions.
Conclusion: Saudi dentists showed appropriate decision-making attitude toward restorative treatment for approximal caries lesions. However, decision making is influenced by some professional and demographic factors.

Authors: Asiri Mohammed , Alzahrani Mohammed , Alzahrani Haya , Alghamdi Raghad , Alqurashi Jana , Alghmdi Rana , Shamah Hisham , Mohsen Alaa
Published: December 2024

Background: Rhinoplasty is the combination of functional and aesthetic characteristics used in patients with congenital defects, traumatic nasal abnormalities, and changes in the patient's aesthetic appearance. In order to enhance long-term cosmetic outcomes without compromising nasal function, cosmetic rhinoplasty, a common but complex plastic surgery treatment, is continually being improved.
Aim: This study aimed to investigate the perceptions of rhinoplasty in Saudi Arabia, encompassing the understanding of public beauty standards, knowledge, and attitudes.
Methods: A cross-sectional study involved 673 out of 875 participants across Saudi Arabia, between October 2023 and September 2024. The questionnaire was distributed randomly through an online platform, and participants were recruited via popular social media from the general population of Saudi Arabia both male and female participants who are 18 years old and who have not necessarily undergone rhinoplasty. All statistical analyses were performed using the Statistical Package for Social Sciences, version 28.
Results: A majority preferred a straight nose (90.9%) with an upward tip (74.6%), a sharp tip shape (85.3%), narrow nostrils (75.2%), small size (87.5%), and long nose (57.1%). Most study participants, 94.4% have heard of rhinoplasty, with 31.0% knowing its purpose, 24.7% recognizing its functional correction capabilities, and 39.4% understanding it enhances both aesthetics and function. Only 40.6% possess adequate knowledge of rhinoplasty. A slight minority (18.4%) express a desire for rhinoplasty, primarily to improve the appearance of their nose (85.5%). A significant proportion (89.6%) believe it is very important for rhinoplasty patients to be aware of potential complications.
Conclusion: The study revealed notable preferences among participants for specific nasal features, highlighting a societal inclination towards a particular standard of beauty. However, with a moderate awareness of rhinoplasty, there remains a substantial gap in understanding its purpose and potential benefits. This highlights the need for educational campaigns to boost public awareness and understanding of rhinoplasty.

Authors: Aljohnei Reham , Alarabi Rida , Banjer Nuha , Qasim Danya
Published: December 2024

Objective: This study aimed to analyze the demographic, clinical, and ventilatory variables associated with extubation failure in pediatric intensive care patients.
Methods: A retrospective observational study was conducted at King Salman Medical City Hospital, Medina, Saudi Arabia, involving 35 pediatric patients (aged 1 month to 14 years) who underwent extubation after mechanical ventilation. Data collection relied on reviewing paper-based and electronic medical records, using standardized forms to extract relevant information. Data were collected on patient demographics, medical history, cause of pediatric intensive care admission, ventilatory parameters, and post-extubation outcomes.
Results: The majority of patients were infants (n = 21, 60.0%), where most had hemoglobin levels below 10 g/ dl (n = 26, 74.3%). Pre-existing syndromic/genetic disorders were present in 15 patients (42.9%), neurological conditions in 13 patients (37.1%), and pre-existing respiratory conditions in three patients (8.6%). Despite thorough pre-extubation preparation, all patients experienced extubation failure (n = 35, 100.0%). Respiratory insufficiency was the primary cause of reintubation (n = 26, 74.3%), followed by neurological causes (n = 6, 17.1%). Nearly all patients were ventilated with tidal volumes of 5-10 ml/kg and positive end-expiratory pressure of 5-10 cm H2O (n = 34, 97.1%). The average time for reintubation was 45.29 hours.
Conclusion: Respiratory insufficiency and neurological factors were significant contributors to extubation failure in pediatric patients. Optimizing ventilatory settings and conducting thorough pre-extubation evaluations, especially in high-risk populations, are crucial. Future research should focus on multi-center studies to explore additional risk factors and potential interventions like non-invasive respiratory support to improve extubation success and reduce reintubation rates in pediatric ICUs.

Authors: Alfahhad Lara , Assiri Raghad , Alajlan Lama , Alshahrani Aljawharah , Aljarbou Alanoud
Published: December 2024

Objective: This study aimed to assess the prevalence of functional constipation (FC) among children and adolescents and to evaluate associated risk factors in Saudi Arabia.
Methods: A cross-sectional study was conducted using a validated online questionnaire that was distributed among participants recruited from the different regions of Saudi Arabia. Children and adolescents aged 4-17 years were included. The Rome IV diagnostic questionnaire for pediatrics functional gastrointestinal disorders was used to collect data. The Arabic version, provided and lingually approved by the foundation committee, was used in the current study.
Results: The overall prevalence of FC was 38.6% (95% CI 35.44%-41.84%). The prevalence of FC was associated with factors such as nationality, living setting, parental education, and maternal age, but not with average monthly income. Mothers of children with FC had a lower average age (30.3 years) compared to those without FC (35.2 years, p < 0.001). FC prevalence was higher in non-Saudi children (56.7% vs. 35.7%, p < 0.001) and in rural areas (54.6% vs. 34.6%, p < 0.001). Children of mothers and fathers with college and post-graduate degrees had a significantly lower prevalence of FC (p < 0.001).
Conclusion: The study revealed a relatively high prevalence of FC among children and adolescents in Saudi Arabia and identified several associated risk factors. Further research is encouraged to investigate the complex interactions between these variables and to develop targeted interventions to reduce FC prevalence and improve the overall well-being of children and adolescents in Saudi Arabia.

Authors: Alsahli Fahad , Alfraih Feras , Alkhuyauli Saad , Malki Hussam , Ibnjlkhaf Fawaz
Published: December 2024

One of the main causes of disability in the globe is stroke. Better clinical outcomes from stroke therapy and diagnosis depend on timely intervention. It is crucial to diagnose stroke subtypes quickly and accurately. In addition to the clinical evaluation of stroke severity using the National Institute of Health Stroke Scale, the current gold-standard method for stroke assessment calls for brain and neurovascular imaging. However, each imaging modality has its advantages and disadvantages. Therefore, this review focused on overviewing stroke diagnostic imaging modalities. This review was established by searching the databases for relevant articles. Physicians make their decision to preserve the patient's life based on the nature and complexity of the stroke. However, some disabilities persist after surgery and proper management. To diagnose a stroke, the most suitable and accessible modality must be used. Computed tomography scans are the primary choice for imaging acute stroke patients as they are readily available, quick to obtain, and have a higher diagnostic sensitivity for intracerebral bleeding. Certain hospitals adopt a fast magnetic resonance imaging stroke protocol during the limited window of time for thrombolytic therapy.

Design and Implementation of Solar-Powered Pumping System in IKN Nusantara Area
Authors: Hebert Arthur Sigiro  , Prabowo  , Burhanuddin Halimi
Published: December 2024

Solar-powered pumping systems are an alternative to providing a sustainable and independent water source. This system declines the dependency on fossil fuels, which generate no greenhouse gas emissions while operating. This paper presents the design, implementation, and performance testing of a solar-powered submersible water pump in Bumi Harapan and Bukit Raya Village to provide a supplementary water source for residents. To meet the daily water supply requirement of 10 m3 in two identical water towers, a 1.1 kW rated power water pump and a 2.2 kW photovoltaic system are chosen. A solar pump controller with the ability to switch power sources from photovoltaic to grid is used in the system to maintain a consistent water supply if needed. Based on performance simulations using PVSyst software, the designed systems cannot fulfill daily water requirements. However, they are expected to fill both water towers with a daily average supply of 5.78 m3 for the Bumi Harapan site and 9.23 m3 for the Bukit Raya site. These inabilities occurred because the pumps must operate with an elevation head that is more remarkable than the specifications. Performance tests using a solar power meter (SPM) and power quality analyzer (PQA) showed that the electric submersible pump (ESP) will supply water with a flow rate that depends on solar irradiance. Based on the data collection, the ESP successfully operates near its rated capacity during the peak sun hour.

Technological developments and the increase in internet users, estimated to reach 185 million in early 2024, have driven the need for reliable communication network services, especially for underdeveloped, frontier, and outermost (3T) areas in Indonesia, where internet coverage is still minimal. Based on these problems, telecommunications service providers need to prepare appropriate designs to provide optimal service to customers by providing a quality network. Telkomsat offers solutions through satellite-based services, especially very small aperture terminals (VSAT). Quality of service (QoS) testing is carried out by measuring throughput, packet loss, delay, and jitter using transmission control protocol (TCP) and user datagram protocol (UDP) data to compare the performance of VSAT IP and VSAT Star. The results show that VSAT Star is superior in throughput and delay, with an average throughput of 8.79 Mbps and an average delay of 12.32 ms. This is better than VSAT IP which only produces 6.43 Mbps and 83.94 ms. Both services have the same average packet loss of 0%. However, VSAT IP is more stable in terms of jitter with an average value of 0.36 ms compared to VSAT Star which produces 1.05 ms. In the ping test to the public domain (Google.com), VSAT Star showed an excellent average value of 38.55 ms compared to 584.05 ms for VSAT IP. Overall, VSAT Star has greater potential because of its advantages such as auto point, larger bandwidth, and lower delay.

In response to the issues of air pollution, temperature, and noise, this project attempts to create an air quality, temperature, and noise monitoring system using Internet of Things (IoT) technology. This system will comprise physical components and a web platform that delivers real-time environmental reports. Users can readily obtain information regarding air quality, temperature, and noise levels via this platform, which takes advantage of the internet's accessibility. This Internet of Things-based device monitors environmental quality in six high-traffic areas in Malang, Indonesia. The system uses various sensors to monitor air quality, temperature, humidity, dust levels, carbon monoxide (CO), carbon dioxide (CO2), and noise pollution in real-time. Data was collected during peak traffic hours, demonstrating the direct influence of car emissions on air quality.  The findings show that some regions' CO and particulate matter levels surpass safe criteria, notably during peak traffic periods, but CO2, humidity, and noise levels are below acceptable norms. These findings highlight the necessity for urban air pollution reduction initiatives. Additional sensor calibration and communication modifications are recommended to increase system accuracy and dependability. This study gives significant insights for local authorities to manage urban environmental quality and safeguard human health.

Linguistic and cultural landscapes in interdisciplinary interaction: modern approaches to research
Authors: Ragulina Milana Vladimirovna
Published: December 2024

The article is devoted to the analysis of modern approaches to the study of linguistic and cultural landscapes in the context of interdisciplinary research. Linguistic landscape, as a scientific concept and approach, took shape in the 1990s. Initially focused on visible linguistic signs, it rapidly assimilates polymodal aspects of linguistic space. Such space expands from the physical to the social, symbolic and virtual. The study of the cultural landscape began with morphological and scientist branches. They developed over the course of a century, and by the end of the XXth century were enriched by the inclusion of spatial symbols, semantics, narratives and competing sociospatial discourses. The subject of the study is the analysis of interpretations of linguistic and cultural landscapes, approaches and methods formulated under the influence of worldview paradigms. The methodological basis is a comparative analysis of subject areas based on new cultural geography, sociology and linguistics. The novelty of the study lies in comparing key metaphors and trends in the theoretical evolution of the concepts of linguistic and cultural landscape, finding potential points of contact and mutual integration. The trajectories of theorizing linguistic and cultural landscapes reveal a substantive similarity with different rates of development of new research domains. As a result, the evolution of linguistic and cultural landscapes studies, the expansion of their subject area, the formation of fields of attraction and new opportunities in the study of personality, society and space were revealed. The potential for interdisciplinary interaction of the concepts of linguistic and cultural landscapes with related disciplines is considered: ethnogeography, cultural geography, philosophy and cultural studies. It is shown that the integration of linguolandscape and cultural-landscape approaches can help resolve methodological difficulties encountered in the study of local communities and thair ethnocultural landscapes.
