Authors: Li Jinze , Ma Tianhong , Liu Xin , Xi Jiawei , Deng Li , Sun Hao , Yang Yanxin , Li Xiang
Published: April 2024

With the in-depth study of solid-state batteries (SSBs), various in situ and ex situ characterization technologies have been widely used to study them. The performance and reliability of SSBs are limited by the formation and evolution of lithium dendrites at the interfaces between solid electrodes and solid electrolytes. We propose a new method based on optical coherence tomography (OCT) for in situ characterization of the internal state of solid-state batteries. OCT is a low-loss, high-resolution, non-invasive imaging technique that can provide real-time monitoring of cross-sectional images of internal structures of SSBs. The morphology, growth, and evolution of lithium dendrites at different stages of cycling under various conditions can be visualized and quantified by OCT. Furthermore, we validate and correlate the OCT results with scanning electron microscopy (SEM) and XPS, proving the accuracy and effectiveness of the OCT characterization method. We reveal the interfacial phenomena and challenges in SSBs and demonstrate the feasibility and advantages of OCT as a powerful tool for in situ and operando imaging of battery interfaces. This study provides new insights into the mechanisms and factors that affect SSB performance, safety, and lifetime, and suggests possible solutions for improvement and application in the field of applied energy.
Europeanization as Pragmatic Politics: Italy’s Civil Society Actors Operating in the Face of Right-Wing Populism
Authors: Mat Fazila , Chiodi Luisa , Schmidtke Oliver
Published: April 2024

This article examines how and under what conditions Italy’s civil society organizations (CSOs) have resorted to transnational activism and to what extent these efforts translate into impactful political advocacy. The analysis focuses on the action strategies of these civil society actors that have come under considerable pressure through the resurgence of populist–nationalist actors in the domestic arena. Developing an actor-centred perspective from below, this article draws on a series of 27 interviews conducted with these organizations’ representatives working primarily on issues related to migration and refugees in Italy. The empirical study examines some key initiatives that see domestic CSOs as protagonists in the transnational realm and explicates their motivations, approaches, and experiences. Conceptually, the article distinguishes between the vertical and horizontal Europeanization of CSOs. While there are notable opportunities for CSOs to engage in Brussels-centred governance and policy making, the effectiveness of horizontal Europeanization in the form of cross-border networking is—at first sight paradoxically—limited by the EU’s system of multi-level governance. The central argument about Europeanizing civil society activism is that these processes are primarily driven by a pragmatic pursuit of solutions to concrete political challenges that could not be properly addressed in an increasingly hostile domestic environment.

Published: April 2024

Soccer organizations generally adopt deterministic models within their talent pathways. In this framework, early ability and results are emphasized, leading to selection biases, such as birth advantages (i.e., relative age effects and birthplace effects), which research has shown affect both early developmental experiences and continued sporting involvement. Accordingly, this study aimed to (a) provide further test of birth advantages in Italian youth soccer by exploring the birth quarter (BQ) and birthplace (BP) distribution of 1050 male Italian players born between 1999 and 2001 who competed in the national U17 championship throughout the 2015–16 season and (b) investigate how birth advantages influenced selected players’ future career status. Chi-square goodness-of-fit tests revealed early born players, and players born in North Italy were overrepresented at the youth level (p-values < 0.0001). Successive prospective analysis revealed only 18% of players developed into professional-level soccer players. Chi-square tests of independence indicated that players’ BP was associated with their future career status (p < 0.0001), whereas their BQ was not (p = 0.459). Odds ratios showed players born in North Italy were five times more likely to complete the youth-to-senior transition than those born in South Italy. These findings highlighted environmental factors influence Italian players’ early developmental experiences and their future career status.

Spodoptera frugiperda (fall armyworm, FAW) is a significant economic pest of maize in Uganda. Many Ugandan maize farmers employ synthetic insecticides as their main form of control despite the negative impacts of these chemicals. We tested the effectiveness of Beauveria bassiana; General Biopesticide Cocktail (mixture of B. bassiana, M. anisopliae, Isaria fumosoroseus, Lecanicillium lecani and Purporeocillium lilacanus three strains of Metarhizium anisopliae, Nimbecidine® (azadirachtin 0.03%EC), and Roket® (cypermethrin 4% and profenofos 40%); and Amdocs® (emamectin benzoate 2% and abamectin 1%) on fall armyworm and parasitoids, respectively, in 2020 and 2021. The treatments with the greatest decrease in leaf damage and infestation were Amdocs® and Roket®, followed by Nimbecidine®. The biopesticides were not always more effective than the untreated control, though; their efficacy was often lower than that of the synthetic and botanical pesticides. We recovered one egg parasitoid, Telenomus remus, and seven egg and egg-larval parasitoids (Coccygidium luteum, Coccygidium sp., Cotesia icipe, Chelonus sp., Micranisa sp., Charops cf. diversipes, and an unidentified Tachinidae). Among these, C. cf diversipes, Chelonus sp., C. luteum, C. icipe and the Tachinidae were the most abundant. Parasitism was low, averaging 10% for egg masses and 5.3% for larvae. Application of synthetic pesticides and Nimbecidine® often resulted in higher yield when compared with the untreated control. In general, a low population of parasitoids was observed. Although the parasitoid population reduced in plots treated with Amdocs® and Roket®, the percentage of parasitism of FAW was not affected. In some instances, higher yields were realized in untreated control when compared with the treated plots. Pest management practices more compatible with biological control need to be considered for the management of fall armyworm.

Published: April 2024

Dubai, a popular vacation spot, has launched an initiative to reduce reliance on single-use plastic water bottles. Tourists in Dubai widely utilize PET (Polyethylene Terephthalate) water bottles, and significant quantities of greenhouse gases (GHG) are released during the production and disposal of PET bottles. In response to Dubai’s initiative, some hotels eliminated PET bottles and substituted them with environmentally favorable alternatives. These hotels are considered adopters of the initiative, while other hotels that might follow are imitators. Thus, innovation diffusion theory (IDT) is used in this work to forecast the transition of hotels to non-PET bottles. The diffusion of this new behavior is simulated using a system dynamic (SD) model, where factors pushing imitators to abolish PET bottles are found using the Delphi method and hotel surveying. Moreover, the importance of each identified factor is found using an analytical hierarchical process (AHP). Since hotels are divided into several categories based on their service quality, the analysis shows that hotels are affected by other hotels in their category or better categories. Using this conceptual understanding, Bass and generalized Bass modeling are used in the SD model to study how imitating hotels will follow the adopters. Best-, average-, and worst-case scenarios are studied to help decision-makers understand what to expect in the future. For the best- and average-case scenarios, the SD simulation shows that all hotels will potentially have abolished PET bottles in 25 years. However, only 16% of hotels will have cancelled PET bottles in 25 years if the worst-case scenario occurs; thus, decision-makers need to intervene to expedite the process.
Research on the Construction of a Composite Humanistic Forest Ecological Corridor in the Main Urban Area of Daqing City
Authors: Jing Zhongwei , Chen Peng
Published: April 2024

The essential significance of forest ecological corridors primarily revolves around their role in enhancing and maintaining balance in the ecological environment. However, an aspect that has not been adequately addressed is their potential in terms of recreational services. Focusing on the main urban area of Daqing City, this research investigates the integration of ecological and recreational objectives, adopting an “ecology-humanity” composite perspective. (1) Morphological Spatial Pattern Analysis (MSPA) and connectivity analyses were employed to identify ecological sources and construct an ecological resistance framework, and potential corridors were then delineated under ecological scenarios using the Minimum Cumulative Resistance (MCR) model; (2) then, the resistance system was refined using ArcGIS network analysis to identify potential corridors for recreational scenarios; (3) finally, this study examined the network layout of ecological and recreational routes, aiming to integrate an optimal humanistic configuration of forest ecological corridors that aligns with dual objectives. The spatial distribution of forest ecological corridors in Daqing City’s main urban area reveals a pattern where densely constructed areas predominantly feature recreational corridors and less-developed regions are characterized by ecological corridors. Ecological composite corridors serve as crucial links between these types of areas, mainly enhancing the urban layout and refining its structure.
Study of a New Photocatalytic Film Process Combined with a Constructed Wetland and an Analysis of Reoxygenation Pathways in a Water Body
Authors: Chen Shihao , Ye Ming , Chen Nuo , Pan Wenbin , Dai Wenxin
Published: April 2024

Pollution in water environments hinders both social progress and economic development. Wastewater treatment and the sustainable use of water resources are important factors in solving this problem. In a previous study, the authors proposed a process that used photocatalytic film as a back-end treatment in a composite iron–carbon constructed wetland (WIC&PF) to restore a mildly eutrophic water body. This method has strong reoxygenation effects, and can efficiently remove pollutants; these are qualities that have not been mentioned in previous studies regarding constructed wetlands. In this study, the authors further investigated the effectiveness of this process by using a photocatalytic film as a front-end treatment for a composite iron–carbon constructed wetland (PF&WIC) to restore a mildly eutrophic water body. The results showed NH4+-N, TN, TP, COD, and chlorophyll a removal rates using PF&WIC of 79.1 ± 6.6%, 76.8 ± 6.5%, 77.0 ± 5.4%, 77.3 ± 7.2%, and 91.7 ± 5.6%, respectively. The DO concentration of the water body increased compared with that of the effluent. The bacterial species and their abundance in the lake water also changed significantly, and photosynthetic autotrophic bacteria (Cyanobium PCC-6307) became the most dominant bacteria, and this played an important role in reoxygenating the water body. In comparing these results to those of our previous study, the removal of pollutants with PF&WIC was close to that with WIC&PF, but the reoxygenation effect of PF&WIC on the water body was significantly worse than that of WIC&PF; thus, WIC&PF is the more reasonable choice for treating eutrophic water bodies.

Published: April 2024

In order to ensure sustainability in the agricultural sector and to meet global food needs, a particularly important challenge for our time is to investigate the possibility of increasing agricultural production in areas with extreme hyper-arid environments. Warming air temperatures and sandy soils significantly influence tree root water uptake (RWU) dynamics, making accurate estimation of RWU depth distribution and magnitude crucial for effective resource management, particularly in the context of precision irrigation within agroecosystems. This study employed two non-invasive techniques, namely HYDRUS 1D and electrical resistivity tomography (ERT), to simulate RWU under controlled experimental conditions and under an extreme hyper-arid environment. The results revealed that the highest RWU rates occurred during the morning (08:00–11:00). RWU activity predominantly concentrated in the upper soil profile (0–30 cm), and the soil water content in this area was notably lower compared to the deeper soil layers. With increasing temperature, there was a tendency for the RWU zone to shift to lower depths within the soil profile. The findings of this study could have important implications for farmers, providing valuable insights to implement irrigation water management strategies.

Authors: Kontogianni Elli , Anthopoulos Leonidas
Published: April 2024

Metaverse has become an emerging trend for both academia and industry, and it seems to concern the next generation of the Internet. Although it is still in its grassroots, metaverse is estimated to bring disruption to people’s lives. One of the effects concerns the generation of new value opportunities that don’t exist in real life. These new types of value as well as their impact on people’s lives must be explored. In this respect, this paper utilizes literature evidence to define the value types of metaverse, which are circulated with experts from the focus group on metaverse of the International Telecommunications Union. Results uncover economic, public, and social values that metaverse generates, which can ensure its financial viability and the community’s social sustainability. The economic value sources come from both the industrial and the commercial sectors, while the public values concern citizen empowerment and government efficiency. The social values of metaverse concern employment growth, and the provision of immersive experiences in entertainment and education environments. Finally, this paper critically reviews their role for environmental, economic, and social sustainability. The literature review indicated that metaverse can on the one hand, enhance sustainability but on the other hand, it can cause environmental impact.
Asymmetric Cryptography Based on the Tropical Jones Matrix
Authors: Huang Huawei , Kong Weisha , Xu Ting
Published: April 2024

In recent years, the tropical polynomial factorization problem, the tropical matrix decomposition problem, and the tropical multivariate quadratic equation solving problem have been proved to be NP-hard. Some asymmetric cryptographic systems based on tropical semirings have been proposed, but most of them are insecure and have been successfully attacked. In this paper, a new key exchange protocol and a new encryption protocol are proposed based on the difficulty of finding the multiple exponentiation problem of the tropical Jones matrices. The analysis results indicate that our protocol can resist various existing attacks. The complexity of attacking an MEP by adversaries is raised due to the larger number of combinations in the tropical Jones matrices compared to regular matrix polynomials. Furthermore, the index semiring is the non-negative integer cyclic matrix semiring, leading to a higher efficiency in key generation.

Porcine Deltacoronavirus (PDCoV) is a newly identified coronavirus that causes severe intestinal lesions in piglets. However, the understanding of how PDCoV interacts with human hosts is limited. In this study, we aimed to investigate the interactions between PDCoV and human intestinal cells (HIEC-6) by analyzing the transcriptome at different time points post-infection (12 h, 24 h, 48 h). Differential gene analysis revealed a total of 3560, 5193, and 4147 differentially expressed genes (DEGs) at 12 h, 24 h, and 48 h, respectively. The common genes among the DEGs at all three time points were enriched in biological processes related to cytokine production, extracellular matrix, and cytokine activity. KEGG pathway analysis showed enrichment of genes involved in the p53 signaling pathway, PI3K-Akt signaling pathway, and TNF signaling pathway. Further analysis of highly expressed genes among the DEGs identified significant changes in the expression levels of BUB1, DDIT4, ATF3, GBP2, and IRF1. Comparison of transcriptome data at 24 h with other time points revealed 298 DEGs out of a total of 6276 genes. KEGG analysis of these DEGs showed significant enrichment of pathways related to viral infection, specifically the PI3K-Akt and P38 MAPK pathways. Furthermore, the genes EFNA1 and KITLG, which are associated with viral infection, were found in both enriched pathways, suggesting their potential as therapeutic or preventive targets for PDCoV infection. The enhancement of PDCoV infection in HIEC-6 was observed upon inhibition of the PI3K-Akt and P38 MAPK signaling pathways using sophoridine. Overall, these findings contribute to our understanding of the molecular mechanisms underlying PDCoV infection in HIEC-6 cells and provide insights for developing preventive and therapeutic strategies against PDCoV infection.

We aimed to assess the prevalence of nasopharyngeal pneumococcal carriage and to determine serotype distribution, antibiotic susceptibility patterns, and evolutionary dynamics of Streptococcus pneumoniae isolates in healthy under-five children. Nasopharyngeal swabs were collected from healthy children over three survey periods between 2020 and 2022. All pneumococcal isolates were serotyped and tested for antimicrobial susceptibility. A total of 309 S. pneumoniae isolates were collected, with an overall prevalence of nasopharyngeal pneumococcal carriage of 24.4% (CI95%: [22–26.8%]). These isolates were classified into 25 different serotypes. The most common serotypes were 14 (14.9%), 19F (12%), 6B (10.4%), and 23F (7.4%), which are covered by the PCV10 vaccine, as well as 19A (8.4%) and 6A (7.8%), which are covered by the PCV13 vaccine. A significant decrease in the proportion of serotype 19F (p = 0.001) and an increase in serotypes 19A (p = 0.034) and 6A (p = 0.029) were observed between the three survey periods. Multidrug resistance (MDR) was noted for 56.6% of the isolates. A significant association with antimicrobial resistance was observed for the most frequent serotypes, mainly serotype 19A. In conclusion, one-quarter of healthy under-five children in Tunisia carried S. pneumoniae in their nasopharynx. A dominance of vaccine serotypes significantly associated with antimicrobial resistance was recorded.

Insect venom is one of the most common triggers of anaphylaxis in the elderly population. Venom immunotherapy (VIT) remains the only treatment for Hymenoptera venom allergy (HVA). However, little is known about the differences in indication for VIT in the group of patients aged 60 years and older. The objective of this study was to assess the clinical and diagnostic differences of HVA in elderly patients. The study compared data from patients aged ≥ 60 (N = 132) to data from patients aged from 11 to 60 years (N = 750) in terms of HVA severity, comorbidities, and immunological parameters, namely, intradermal testing (IDT), specific IgE (sIgE) levels against extracts and major allergenic molecules, and serum tryptase level (sBT). The severity of systemic HVA (I–IV Müller scale) did not differ between adults and seniors. However, the severity of cardiovascular reactions (IV) increased with age, while the frequency of respiratory reactions (III) decreased. No differences were found in the immunological parameters of sensitization IDT, venom-specific IgE concentrations, or sIgE against Api m 1, 2, 4, 5, and 10 between patients below and above 60 or 65 years of age. Differences were noted for sIgE against Ves v1 and Ves v5; they were higher and lower, respectively, in seniors. In the seniors group, sBT levels were higher. Elevated tryptase levels, along with the aging process, can represent a risk factor within this age category. Nevertheless, advanced age does not influence the immunological parameters of immediate HVA reactions, nor does it impact the diagnosis of HVA.
Vaccines Induce Homeostatic Immunity, Generating Several Secondary Benefits
Authors: Arunachalam Arun B.
Published: April 2024

The optimal immune response eliminates invading pathogens, restoring immune equilibrium without inflicting undue harm to the host. However, when a cascade of immunological reactions is triggered, the immune response can sometimes go into overdrive, potentially leading to harmful long-term effects or even death. The immune system is triggered mostly by infections, allergens, or medical interventions such as vaccination. This review examines how these immune triggers differ and why certain infections may dysregulate immune homeostasis, leading to inflammatory or allergic pathology and exacerbation of pre-existing conditions. However, many vaccines generate an optimal immune response and protect against the consequences of pathogen-induced immunological aggressiveness, and from a small number of unrelated pathogens and autoimmune diseases. Here, we propose an “immuno-wave” model describing a vaccine-induced “Goldilocks immunity”, which leaves fine imprints of both pro-inflammatory and anti-inflammatory milieus, derived from both the innate and the adaptive arms of the immune system, in the body. The resulting balanced, ‘quiet alert’ state of the immune system may provide a jump-start in the defense against pathogens and any associated pathological inflammatory or allergic responses, allowing vaccines to go above and beyond their call of duty. In closing, we recommend formally investigating and reaping many of the secondary benefits of vaccines with appropriate clinical studies.
Canine Prostate Cancer: Current Treatments and the Role of Interventional Oncology
Authors: Gibson Erin A. , Culp William T. N.
Published: April 2024

Prostate carcinoma is one of the most common cancers worldwide in men, with over 3 million men currently living with prostate carcinoma. In men, routine screening and successful treatment schemes, including radiation, prostatectomy, or hormone therapy, have allowed for high survivability. Dogs are recognized as one of the only mammals to spontaneously develop prostate neoplasia and are an important translational model. Within veterinary medicine, treatment options have historically been limited in efficacy or paired with high morbidity. Recently, less invasive treatment modalities have been investigated in dogs and people and demonstrated promise. Below, current treatment options available in dogs and people are reviewed, as well as a discussion of current and future trends within interventional treatment for canine PC.

Published: April 2024

Concrete waste recycling processes involve multiple stages, equipment, and procedures which produce Fine Recycled Concrete Aggregates (FRCA) for use in construction. This research aims at performing a comprehensive overview of the recycling technologies, recycling processes, and normative requirements to produce high-quality FRCA and to investigate the influence of these processes on their physical properties. The properties investigated were the particle size distribution (PSD), water absorption, oven-dry density, and adhered paste. The correlations between these properties were also investigated. The results indicate that the recycling processes with the highest potential for producing high-quality aggregates demand jaw crusher and impact crusher combinations. These processes are better suited for achieving FRCA with the desired particle size distribution and oven-dry density. However, water absorption and adhered paste, which are critical factors for obtaining high-quality FRCA, seem to be more dependent on the original material than on the recycling process.
Elucidating Electrochemical Energy Storage Performance of Unary, Binary, and Ternary Transition Metal Phosphates and their Composites with Carbonaceous Materials for Supercapacitor Applications
Authors: Karim Muhammad Ramzan Abdul , Shehzad Waseem , Khan Khurram Imran , Haq Ehsan Ul , Haroon Yousaf
Published: April 2024

Transition metal compounds (TMCs) are being researched as promising electrode materials for electrochemical energy storage devices (supercapacitors). Among TMCs, transition metal phosphates (TMPs) have good, layered structures owing to open framework and protonic exchange capability among different layers, good surface area due to engrossed porosity, rich active redox reaction sites owing to octahedral structure and variable valance metallic ions. Hence TMPs become more ideal for supercapacitor electrode materials compared to other TMCs. However, TMPs have got some issues like low conductivity, rate performance, stability, energy, and power densities. But these problems can be addressed by making their composites with carbonaceous materials, e.g., carbon nanotubes (CNTs), graphene oxide (GO), graphitic carbon (GC), etc. A few factors like high surface area, excellent electrical conductivity of carbon materials and variable valence metal ions in TMPs caused great enhancement in their electrochemical performance. This article tries to discuss and compare the published data, majorly in last decade, regarding the electrochemical energy storage potential of pristine unary, binary, and ternary TMPs and their hybrid composites with carbonaceous materials (CNTs, GOs/rGOs, GC, etc.). The electrochemical performance of the hybrids has been reported to be higher than the pristine counterparts. It is hoped that the current review will open a new gateway to study and explore the high performance TMPs based supercapacitor materials.

Dziedzictwo konfliktu klasowego a lokalna polityka pamięci
Authors: Rek-Woźniak Magdalena
Published: April 2024

The conceptual framework of “difficult heritage” was developed in studies concerning various forms of collective violence. This article is grounded on the assumption that it can also be applied in the context of socio-economic inequalities, since under the hegemonic dominance of interpretations of the past that conform to the interests of the elite, the experiences of subordinated categories become “troublesome.” As such, stories of both oppression and emancipation are forgotten or neutralized. From this perspective, the mechanisms of obscuring and mainstreaming of collective interests and related conflicts as elements of “legitimate” history seem particularly interesting. Drawing on the notions of agonistic memory and museum as agonistic space, the author analyses the permanent exhibition at the Central Museum of Textiles in Łódź, reinterpreting the local history of industrial development. The paper aims to determine the place of industrial conflict in the narrative of the history of an industrial city. It is organized around three questions. First of all, what aspects of industrial relations are discussed in the museum narrative? Are they framed mostly by structural determinants or rather presented as individual and collective experience? Secondly, how are these relations contextualized? And thirdly, which modes of narrative are engaged? And is the conflict between workers and those in charge of the means of production a moral or rather a socio-political issue?

Published: April 2024

En este estudio se analizó la contaminación atmosférica por partículas suspendidas PM2.5 de la ciudad de Morelia, Michoacán México. Se realizaron análisis de varianza (ANOVA) no paramétrico y métodos de correlación y regresión, para evaluar la relación entre las PM2.5 con monóxido de carbono (CO), ozono (O3) y PM2.5 registrados en dos sitios de monitoreo en Morelia y 1 en la Zona Metropolitana de la ciudad de México. En términos generales, el centro de Morelia predominó con altas concentraciones de PM2.5 en comparación con los observados en la Enes-UNAM, campus Morelia y la estación Merced del centro de la ciudad de México. Asimismo, la contaminación por PM2.5 en Morelia, aumentó 53% del periodo 2015-2023; los meses con mayor incremento fueron enero, febrero y marzo 2023 con 84%, 65% y 106% respectivamente.
 
También, se reporta el incremento histórico de 46 días por encima de la norma oficial mexicana NOM-025-SSA1-2021, que establece como límite 41µg/m3 de PM2.5 como promedio diario, de los cuales 8 días fueron consecutivos, sobre todo en mayo 2023 debido en parte a las quemas agrícolas e incendios forestales ocurridos en la periferia de Morelia. Pero el número de días, se debió al cambio del valor anterior de 45µg/m3 reglamentado en la NOM-025-SSA1-2014.

Neste trabalho, foi avaliada a remoção de triclosan em solução aquosa através da aplicação de um sistema contendo biofilme em reator batelada. O suporte utilizado foi o carvão ativado de casca de coco na granulometria de 8-12 mesh. As concentrações de triclosan avaliadas foram: 5,62 ± 0,01, 9,34 ± 0,66 e 14,37 ± 0,88 mg L-1, com pH inicial na faixa de 6,7 – 7,07 e velocidade de agitação de 150 rpm. Os resultados demonstraram que a quantidade de biomassa aderida ao suporte foi de 8,29 mg gsuporte-1, chegando a 100% de remoção de Triclosan em 100 min de tempo de contato para a concentração de 14,37 ± 0,88 mg L-1 e 45 min para as demais concentrações estudadas. Com relação aos parâmetros cinéticos, obtidos através do modelo cinético de Michaelis-Menten, o valor da constante de meia saturação relativa ao triclosan (KA) indicou uma maior afinidade pelo efluente com maior concentração. A velocidade de degradação (avRma), foi maior para as menores concentrações. Os resultados indicam que o processo de biodegradação de triclosan em solução aquosa utilizando carvão ativado como suporte para biomassa é possível e pode ser aplicado para efluentes contendo este contaminante emergente.
DEVELOPMENT AND RECOVERY MANAGEMENT OF TOURIST DESTINATIONS USING THE EXAMPLE OF KYIV CITY: OVERCOMING CONSEQUENCES OF THE NEGATIVE IMPACTS

Published: April 2024

The development of tourism at the destination level is closely linked to its attractiveness, which determines the prospects and opportunities for attracting tourist flows. New trends in the development of modern tourism as a socio-economic, cultural, and communicative institution require regional tourism entities to take appropriate practical measures. Increasing tourist flows requires the creation of an appropriate infrastructure, including the expansion of the network of accommodation facilities, the development of transport links and other services necessary to meet the needs of tourists. Political instability and the lack of a comprehensive, systematic model of tourism management have led to the decline of this sector in Ukraine. The relevance of this topic is driven by the need to develop strategies and management measures to ensure the attractiveness of urban destinations for tourists and to restore the tourism sector in line with international management models and examples of major urban tourist destinations. The main purpose of this study is to analyze the aspects of management, development, and recovery of a tourist destination on the example of Kyiv as part of Ukraine’s economic system in the context of a pandemic and war. The study uses systemic analysis, structural and functional approaches, as well as comparison methods. The study examines the problems associated with a decrease in tourist flow and loss of revenue in the tourism industry due to ineffective management of the tourist destination (pandemic and military operations in the country) and insufficiently developed infrastructure. This made it possible to formulate recommendations for solving problems, namely: improving transport infrastructure and creating and maintaining tourist infrastructure, such as hotels, restaurants and other facilities that will form an open state tourism policy. The concept of spatial-economic management and practical functionality of tourist destinations on the example of Kyiv is developed, provided that modern technologies, approaches, and methods of tourist destinations formation are used, which are components of the model of management of tourist areas development. The results of the study can be used to manage tourist destinations at the international and regional levels.
GLOBAL VALUE CHAINS AS THE MAIN INSTITUTE OF CONTEMPORARY CREATIVE BUSINESS RELATIONSHIPS

Published: April 2024

Research into the creation and functioning of global value chains helps today's economists, business analysts, and policy makers make informed decisions to improve the global economic landscape and ensure sustainable development for all countries. The article examines the influence of global value chains on the world economy. The work uses the method of the unity of historical and logical analysis. Methods of comparative, causal and functional analysis, principles of system analysis, dialectical approach in the study of processes and phenomena are also used. The concept of the "smile curve" was analyzed to highlight the unevenness of the distribution of added value in different segments of the production chain. They point out that GVS often concentrate maximum value in research and development and post-production services. A study of the "sad smile" phenomenon highlighted that industries moving from mass production to personalization through artificial intelligence technologies may experience cost reduction in the initial and final stages of production. At the same time, companies located in the country of origin receive the greatest added value. The article focuses on the challenges that developing countries face in trying to get out of the "middle-income trap." Such challenges include tariff barriers, concentration of patents on knowledge and financing in these countries. The article argues that the GVS institute contributes to the appropriation of imperialist rent by the countries of the center at the expense of the countries of the periphery. Global chains enable the capital of the North to exploit the cheap labor of the South, keeping their incomes low and affecting their ecology. Recommendations are proposed for effective regulation and redistribution of added value to achieve sustainable global development.
