Waste electrical and electronic equipment (WEEE) is a continuously growing concern, with issues arising from intensive resource consumption and the environmental and human impacts being caused by inadequate practices. The purpose of this study is to evaluate the impacts of end-of-life management options generated by Information Technology (IT) and telecommunication equipment in Romania during the period of 2018–2021 from a sustainability point of view, including environmental aspects, such as greenhouse gas emissions (GHG) and energy consumption, economic aspects, considering workforce earnings and revenues collected for the public budget, and social impacts through job creation. To achieve the main objective, a two-step methodology is used, with one step to determine the relevant quantities of WEEE generated by the subcategories of IT and telecommunication equipment, using the European Union’s WEEE Calculation Tool based on two approaches, WEEE reported in Eurostat (Scenario 1) and apparent consumption (Scenario 2), and a second step to evaluate the environmental, economic, and social impacts of the WEEE management system by applying Waste Reduction Model (US EPA WARM). Regarding the six WEEE categories evaluated, in both scenarios, Flat-Panel Displays is the category with the lowest environmental impact and highest economic and social benefits, while, on the opposite side, the Cathode-Ray Tube (CRT) category displays the highest environmental impact and lowest economic and social benefits.

The preservation of natural heritage is a global concern nowadays, which is equally important for climate resilience and for sustainable resource use. The present research is focused on assessing the trends of natural landscape changes, such as forests, meadows, and pastures, and the preservation of locally kept traditional livestock, and plant varieties as indicators of biodiversity, in the countries of the European Union between 2012 and 2021, using secondary data. The research methodology was a panel analysis according to the Linear Mixed Model method. The results show that while larger areas allocated to agriculture generally enhance plant biodiversity, they have the opposite effect on the number of local livestock breeds. The spreading of organic farming enhances the preservation of local livestock breeds, while the spreading of forest areas is beneficial for plant biodiversity. The share of permanent meadows and pastures increases with increasing agricultural areas, and this also affects plant biodiversity positively. All biodiversity indicators increased during the analyzed period, as did well as the size of forest areas and, permanent meadows and pastures, which reflects the improvement in natural heritage and the enhancement of environmental protection awareness with time. The differences among countries show, that highly developed agriculture does not mean better preservation of natural heritage, nor the opposite, as ecological conditions and agricultural history may influence the natural vegetation and biodiversity. The protection of natural heritage in Europe differs from the rest of the world, as recent agricultural policy of the EU emphasizes the importance of environmental sustainability. The promotion of low-input use in agriculture, however, may be in conflict with the globally increasing demand for food. Full article

Background: Distal forearm fractures were defined as distal radius fractures with concomitant distal ulna fractures, except ulna styloid fractures. Distal forearm fractures are common among geriatric populations, particularly those with osteoporosis. Conventionally, distal forearm fractures are reduced by a double incision approach; however, malreduction and instability of the distal radioulnar joint were not uncommon. We introduced a modified volar dual window approach to treat the distal forearm fracture and evaluate the functional outcomes and complications. Methods: From January 2020 to June 2023, 13 patients with distal forearm fractures underwent open reduction by the modified dual window approach with locking plate fixation. After surgery, splints were applied for two weeks, and the patients underwent postoperative hand therapy for three months. The mean Quick Disabilities of the Arm, Shoulder, and Hand scores, range of motions, grip strength, postoperative radiographic parameters, and complications data were collected. Results: The mean follow-up period was 12.1 months, and the mean age was 52.3 years. Average wrist flexion was 67°, extension 69°, pronation 81°, and supination 79°. Grip strength was 28.3 ± 11.5 kg, which was 88% of the uninjured opposite side. The Visual Analog Scale score during activities was recorded as 0.5 ± 0.9. The mean Quick Disabilities of the Arm, Shoulder, and Hand score was 14 ± 11.5. The postoperative radiographic parameters were as follows: radial height: 10.8 ± 1.7 mm, radial inclination: 22.6 ± 3.7°, volar tilting: 4.0 ± 3.9°, and ulnar variance: −0.4 ± 1.4 mm. All the patients achieved bone union at the final follow-up. Two patients underwent ulnar implant removal due to irritation symptoms. Neither infection, nor neurovascular injury, nor malreduction developed in these patients. Conclusions: The modified volar dual window approach can achieve good wrist function and distal forearm fracture reduction without increasing neurovascular or wound healing complications. This method is an alternative approach for distal forearm fracture, especially in comminuted distal ulna fracture or distal radioulnar joint incongruity. Full article

This article aims to examine the hedging effect of green bonds in the US market, the European market, and the Chinese market on carbon price risk in the European Union Emission Trading System (EU ETS) from 2021 to 2023. By using daily datasets extracted from Bloomberg and the Vector Error Correction Model (VECM), the research provides evidence of the hedging effect of green bonds in all three markets on carbon price risk in the EU ETS. The paper concludes that the hedging ratio is positive for green bonds in the EU and China, while the figure for the US market is negative. Moreover, there is a positive effect of oil prices on carbon returns in EU ETS. Meanwhile, the opposite is found for stock prices. Full article

Today’s generations live in uncertain times. The inflation of violent and unpredictable events over the last two decades, such as the economic crisis or COVID-19 pandemic, has affected the functioning of regions and the daily lives of their residents. Therefore, the socioeconomic level has to be monitored. This article fills the research gap regarding the identification of the impact of recent turbulent events on the development of municipalities in southern Poland. The specific goal is to identify trends in socioeconomic changes in times of change and uncertainty from 2006 to 2021 in 450 municipalities in Małopolskie, Śląskie, and Świętokrzyskie Voivodeships. The research defined model and problem areas among the municipalities regarding the level of development. The analyses employ an original synthetic Level of SocioEconomic Development index (LSED) consisting of 18 diagnostic variables. The study mixed qualitative and quantitative approaches and considered the spatial dimension in statistical analyses. We identified general trends related to the ageing population and housing shortage. Moreover, in municipalities dominated by industry, socioeconomic development was generally constant. The opposite is true for municipalities focusing on tourism or agriculture. The conclusions demonstrate that Poland’s European Union membership was the key driver of the socioeconomic development of the regions and the country at large. The rule of law crisis in Poland and ensuing cuts in EU spending could slow the development down. The crisis brought about by the COVID-19 pandemic might be consequential as well. Full article

Despite the World Health Organization (WHO) advocating a healthy and balanced diet for consumers for many years, inadequate fruit and vegetable (FV) consumption remains a substantial issue with economic, social, environmental, and nutritional implications. This study aims to identify consumer profiles for sustainable fruit and vegetable consumption in the European Union, considering specific demographic and socio-economic factors. The analysis is based on data from the 2019 European Health Interview Survey (EHIS). This article provides a clear understanding of how gender, age, education level, income, and place of residence relate to sustainable FV consumption through a principal component analysis (PCA). By defining consumer profiles linked to sustainable and healthy FV consumption, the study aids in creating cohesive goals for promoting health within European society. The results of the PCA reveal four distinct consumer profiles and enhance our understanding of the factors influencing these profiles. These findings align with previous research, indicating that consumer profiles remain relatively consistent. According to the PCA classification, sustainable fruit and vegetable consumption is more prevalent among women, educated individuals, higher-income consumers, and those over 55 years old. In contrast, the opposite profile consists of consumers with lower income, younger and middle-aged individuals, men, and those with less than a high school education, highlighting the need for effective strategies to promote a healthier diet in this group. Countries with lower economic development, reflected in consumer incomes, deviate the most from the recommended “at least five portions of fruit and vegetables a day” consumption pattern, and do not exhibit a sustainable consumption model. Thus, continued monitoring of consumer profiles is essential, with a focus on both the quantity and frequency of fruit and vegetable consumption, as well as strategies aiming to increase their intake.

Medicinal plants grown in natural settings are exposed to different adverse environmental conditions that determine their growth and development as well as the composition and concentration of secondary metabolites in their organs. The objective of this study was to evaluate the effects of environmental conditions associated with localities and annual growth cycles on the contents of phenolic compounds and flavonoids, antioxidant activity and potentially bioactive phenolic acids in the roots of Eryngium montanum, a medicinal species from temperate Mexico. The samples for composition analysis were collected using a bifactorial design: Factor A consisted of the localities (Morelos and La Unión de San Martin Huamelulpam, Mexico) and Factor B was represented by the annual growth cycle (2020 and 2021). In each sample, the contents of polyphenols and equivalent flavonoids of quercetin and catechin and antioxidant activity were evaluated using spectrophotometry. Subsequently, chlorogenic, caffeic and rosmarinic acids were identified and quantified using high-performance liquid chromatography with diode-array detection (HPLC-DAD). The annual growth conditions and, to a lesser extent, the locality of origin of the samples significantly influenced the contents of phenolic compounds and antioxidant activity. The environmental conditions that occurred in 2021 favored an increase in the contents of phenolic compounds compared to those in 2020, and the same pattern was observed for chlorogenic acid; however, for caffeic and rosmarinic acids, the opposite pattern was observed. The content of phenolic acids in the roots of E. montanum follows different and independent patterns between cycles based on the interaction between the locality of origin and annual growth cycle. This study quantifies the magnitude of the total environmental effect on the phenolic compound concentrations in E. montanum roots, which was measured via sampling during two annual growth cycles, where the sampling locations factor had little influence. The bioactive compounds identified in E. montanum roots have the potential for use as alternative medicines, as mentioned by different families from Oaxaca, Mexico. Full article

Stein’s Freedom and Grace (Freiheit und Gnade) phenomenologically describes the experience of grace as the desire, communication, or acceptance of God’s Spirit of Love, accessed in the act of faith motivated by the soul’s otherwise unfulfilled desire for self-mastery. This article first discusses the affordances of Stein’s phenomenology which equip her to see grace as a fulfilment of the natural life of the soul, which is experienced as coming from beyond itself. It then addresses how the individual, personal I fails to satisfy its implicit desire for rational and free action in the natural life of the soul and how, in contrast, its opposite, the graced, liberated life of the soul, allows it to, but not on its own, only through union with God’s Spirit. It proceeds from this existential alternative to show how the treatise unfolds as an investigation of the various a priori possibilities for grace to be experienced and why it makes sense to acknowledge faith as a legitimate source of knowledge, as Stein does in work postdating Freedom and Grace. Finally, it is argued that the treatise is phenomenological in nature and that it does not presuppose either metaphysics or Christian doctrine but instead contributes to underpinning both. This argument simultaneously explains Stein’s own subsequent engagement as a Christian philosopher. Full article

The food industry produces an exorbitant amount of solid waste of petrochemical origin as a result of the increase in the development of new products. Natural polymers are an alternative to this theme; however, their development with adequate properties is a challenge. The union of different polymers in the synthesis of packaging is usually carried out to improve these properties. The combination of agar-agar and chitosan biopolymers show particular advantages through hydrogen bonds and electrostatic attraction between oppositely charged groups, presenting a promising source of studies for the synthesis of green packaging. When combined with natural extracts with active properties, these polymers allow an increase in the microbiological stability of foods associated with lower chemical preservative content and greater environmental sustainability.

In this manuscript, we have examined the CSD (Cambridge Structural Database) to investigate the relative ability of Te and I (in practice, the heaviest chalcogen and halogen atoms) in di- and tri-iododiorganyltellurium(IV) derivatives to establish σ-hole interactions. The geometry around the Te(IV) in this type of compound is trigonal bipyramidal where the stereoactive lone pair at Te(IV) occupies one of the equatorial positions. In the solid state, Te(IV) tends to form pseudo-octahedral coordination by establishing strong noncovalent interactions opposite to the two covalent bonds of the equatorial plane. Such contacts can also be classified as chalcogen bonds following the recommendation of the International Union of Pure and Applied Chemistry (IUPAC). Such contacts have been analyzed energetically in this work using density functional theory (DFT) calculations, rationalized using molecular electrostatic potential (MEP) surface analysis and characterized using a combination of the quantum theory of atoms in molecules (QTAIM) and noncovalent interaction plot (NCIplot) computational tools. Finally, the observation of halogen bonds and type I halogen···halogen contacts is also emphasized and compared to the chalcogen bonds. Energy decomposition analysis has also been performed to compare the physical nature of chalcogen, halogen and type I interactions. Full article

The chemoattractant protein chemerin is protective in experimental hepatocellular carcinoma (HCC), and high expression in HCC tissues of Asian patients was related to a favorable prognosis. Studies from Asia found reduced expression of chemerin in HCC compared to para-tumor tissues while our previous analysis observed the opposite. Aim of this study was to correlate chemerin expression in HCC tissues with disease severity of European patients Hepatocyte chemerin protein expression was assessed by immunohistochemistry in HCC tissue of 383 patients, and was low in 24%, moderate in 49% and high in 27%. High chemerin protein in the HCC tissues was related to the T stage, vessel invasion, histologic grade, Union for International Cancer Control (UICC) stage and tumor size. Chemokine-like receptor 1 (CMKLR1) is a functional chemerin receptor. CMKLR1 protein in hepatocytes was low expressed in HCC tissues of 36%, moderate in tissues of 32% and high in 32% of the HCCs. Tumor CMKLR1 was associated with the T stage, vessel invasion, histologic grade and UICC stage. Notably, sex-specific analysis revealed that associations of chemerin and CMKLR1 expression with HCC progression were significant in males but not in females. The tumor chemerin and CMKLR1 protein expression were not related to steatosis, inflammation and fibrosis grades. In summary, chemerin as well as CMKLR1 protein were related to disease severity of European HCC patients, and this was significant in males. This observation is in contrast to Asian patients where higher chemerin in the tumors was protective. Current analysis provides evidence for ethnicity and sex-related differences of tumor expressed chemerin and HCC severity. Full article

The energy crisis that emerged as a result of the reduction in gas supplies from Russia is very topical and very important. This crisis affects not only Europe but also other world economies. As a result of Russia’s attack on Ukraine and the sanctions imposed on Russia, there was a drastic drop in Russian gas supplies, which triggered an increase in fuel prices and an energy crisis. In order to reduce the risk of insufficient gas supplies, European countries have decided to reuse coal and fossil fuels. This is the opposite direction to decarbonization and a zero-carbon economy. The undertaken research is unique, because the issue of slowing down the direction of decarbonization and returning to fossil fuels has not yet been extensively studied. Therefore, the analysis and research results are new in this area. The European project of green energy production from renewable energy sources that has been implemented so far, which aims to accelerate the implementation of a zero-emission economy, may be slowed down. Moreover, the return to fossil fuels will have a negative impact on climate change. The sharp increase in energy prices and the unexpected growth in the profits of energy companies meant that the European Commission introduced a limit on the revenues of enterprises in the energy sector. Surplus income is to be transferred to other entities to offset the drastic increase in energy prices. The conducted analysis showed how the European Union will try to ensure energy security and what the current actions related to climate protection and moving toward an environmentally friendly economy will be.

Because of growing urbanization and lack of time to prepare meals at home, eating out or getting food delivered have become common trends for many people. The consumption of food from unknown sources may impose an increased chance of contamination with microbiological hazards, especially if sanitary conditions are not met. We evaluated data from health surveillance agencies and scientific articles on foodborne diseases (FBD) reported internationally according to the exposure sites. We observed that the data are influenced by cultural, political, and socioeconomic differences. For instance, in New Zealand, Australia, United States, Denmark and India, the occurrence of FBD outbreaks was greater from foods prepared in commercial establishments and street vendors than from households. Conversely, in China, countries of the European Union and Brazil, the results are the opposite. Additionally, the pandemic imposed new eating behavior patterns, increasing delivery services and foods prepared in so-called “Dark Kitchens”. The underreporting and heterogeneity of data among countries prevented a precise conclusion to the question of whether homemade foods are inherently safer than foods prepared out. Nevertheless, a lower level of development in a country influences its sanitation conditions, as well as the number of street food vendors, the search for cheaper foods, and insufficient knowledge of the population on good hygiene practices, which can all increase the chances of FBD cases.

Performance evaluation is commonly based on objective indicators which do not explicitly consider the role of perceptions. Especially when evaluating countries’ performance, citizens’ perceptions can influence public debate and socio-economic narratives. Since these may influence policy making and countries’ performance, perceptions should not be ignored. The objective of this article is to investigate the presence of discrepancies between objective performance and self-perception (subjective performance) among European Union countries. The aim is to raise awareness of the importance of recognizing biases in performance perception as factors that may hamper European debate, countries’ relations and, thus, the political and social sustainability of the European project. The article considers five spending areas that may influence the public opinion’s assessment about countries’ performance (education, environmental protection, health, public order and safety and social protection) and compares objective and subjective indicators for 28 EU countries from 2007 to 2017 using the distance-to-frontier score methodology. The results indicate that the discrepancies are significant, with a generalized tendency toward overestimation, especially among some Central and Northern European countries. The opposite occurred in Greece and some Eastern European countries. These results represent a starting point for grasping an undervalued aspect of the complexity of the European socio-economic environment. Full article

Nowadays, several real-world decision-making problems concerning falling economies, power crises, depleting resources, etc., require efficient decision-making. To solve such problems, researchers proposed several hybrid models by combining the spherical fuzzy sets with other theories, such as spherical fuzzy soft sets, which is an efficient tool to deal with the uncertainties concerning positive, neutral, and negative memberships in the soft environment. However, all the existing hybridizations of spherical fuzzy sets fail to deal with information symmetrically in a bipolar soft environment. Accordingly, this paper presents a novel hybrid model called spherical fuzzy bipolar soft sets (SFBSSs) by fusing spherical fuzzy sets and bipolar soft sets, considering the opposite sets of parameters in symmetry. An example considering the selection of a chief management officer (CMO) for a multi-national company illustrates the proposed model in detail. In addition, some symmetric properties and algebraic operations of the initiated model, including subset, complement, relative null SFBSSs, relative absolute SFBSSs, extended union, extended intersection, restricted union, restricted intersection, AND, and OR operations, are discussed and illustrated via numerical examples. Further, some fundamental results, namely, commutativity, associativity, distribution, and De Morgan’s laws are presented for SFBSSs. Moreover, by considering the massive impact of hydropower in combating the energy crisis and possible dangers to fish migration, a multi-attribute decision-making problem concerning the ranking of downstream fish passage designs for a hydroelectric project is modeled and solved under the developed algorithm based on SFBSSs. Finally, a comparative analysis discusses the supremacy of the initiated model over its building blocks. Full article
