Scrub typhus is caused by intracellular bacteria belonging to the genus Orientia. Until 2010, the endemic region was thought to be restricted to the Asia–Pacific region. Orientia species have recently been discovered in South America, Africa, Europe, and North America. In accordance with these circumstances, we tried to find new or novel bacterial strains in the Republic of Korea (ROK). We found that a new strain of O. tsutsugamushi formed a unique clade based on a 56-kDa type-specific antigen gene and showed 63.2–77.8% similarity to other strains of the same species. Additionally, we identified another sequence with 99.8% similarity to the O3 strain, which has not been recorded in the ROK and whose pathogenicity remains unknown. These findings confirm the diversity of O. tsutsugamushi strains in the ROK, and highlight the need for continued surveillance and further studies to characterize the pathogenicity of this novel bacterial strain.

Building employee loyalty is a prerequisite for a company to achieve a competitive advantage, high organizational performance, and sustainability. The lack of voluntary leaves does not result in recruitment costs or reduced efficiency during the adaptation period of a new employee. It helps retain knowledge and experience within the organization. The article aims to explore employees’ loyalty in terms of voluntary employment continuity during the pandemic slowdown of COVID-19, when employee loyalty was put to an exceptional test, and identify the factors that have had the most significant impact. This empirical study was carried out for Germany, mainly due to the strength and position of the German economy in Europe and the availability of a large, detailed micro dataset necessary for in-depth econometric analyses. The dataset used in the survey is the fifth wave of the German Linked Personnel Panel—LPP in 2020/21 (N = 7397). A multinomial logit model was used as a research tool. Loyalty appears as an explained variable in four ordered logit models that differ in the set of explanatory variables. The explanatory variables include demographics, job title, working conditions, compensation and rewards, job content, training and career development, teamwork, and relationships with colleagues and superiors. The results confirm the influence of extra-organizational factors, such as age and living in a four- or five-person household, on employee loyalty. However, age seems to be a factor of decreasing importance. Too much complexity of work, manifested by great task variety, working in multiple teams, and the requirement to perform work remotely, harmed employee loyalty during the pandemic. Findings justify building loyalty based on sustainable human resource policies to increase income satisfaction, reasonable workload, competence development, and greater autonomy at work. It is also clear that leadership issues (fairness in contact with superiors and recognition for work) mattered during this challenging time and have a high potential to improve employee loyalty in the future.

The Ohrid trout, Salmo letnica, is an endemic species of Lake Ohrid, one of Europe’s oldest lakes, located on the Albania-North Macedonia border. This species exhibits distinct morphotypes—Salmo letnica typicus, Salmo letnica aestivalis, Salmo letnica balcanicus, and Salmo letnica lumi—that differ in morphology and spawning behaviour. However, the extent of their genetic differentiation remains unclear. This study aimed to investigate the genetic variability and population structure of Salmo letnica morphotypes using the mitochondrial Control Region as molecular marker. We obtained 127 sequences from Salmo letnica morphotypes and compared them with sequences from other species within the genus Salmo. Phylogenetic and clustering analyses revealed no significant genetic structuring among the four morphotypes, suggesting an ecological differentiation not (yet) fixed at mitochondrial level. Additionally, our findings suggest that the modern Salmo letnica population likely originated in Lake Ohrid from Salmo farioides founders through evolutionary differentiation, potentially driven by environmental changes. Future studies incorporating a larger number of samples from both Salmo letnica and Salmo farioides are essential to fully understand the evolutionary and ecological dynamics of Salmo letnica morphotypes.

In recent years, businesses have faced growing pressures from stakeholders, including investors, customers, and regulators, to adopt sustainable practices. These pressures stem from the global focus on environmental, social, and governance (ESG) criteria and their association with risk management and corporate resilience. As a result, understanding the connection between sustainability and performance indicators, such as return on equity (ROE) and return on assets (ROA), is crucial to determine whether sustainable practices positively influence financial outcomes or primarily serve to address external expectations. This study seeks to bridge the gap between theoretical frameworks and empirical evidence by employing a rigorous methodological approach—Structural Equation Modeling (SEM)—to assess the impact of sustainability practices on key performance measures. The inclusion of a diverse range of industries from the US and Europe enhances the relevance of the findings, as it facilitates their generalization across developed economies where sustainability initiatives are highly prioritized. Our results are consistent with prior research demonstrating a positive relationship between sustainability and financial performance, particularly in high-development contexts over a medium-term period. These findings carry important implications for managers and policymakers, emphasizing that sustainability is not a compromise but a catalyst for economic and financial profitability. This study contributes to the literature by illustrating how sustainability can simultaneously advance ethical objectives and enhance financial performance, establishing it as a critical area of focus for both academics and practitioners.

Background/Objectives: Cardiovascular diseases are a leading cause of death, and psychosocial stress is considered a contributing factor to these issues. With the rising number of heart surgeries, proper rehabilitation post-surgery is essential. Previous studies have demonstrated the positive impact of yoga and transcendental meditation on the cardiovascular system. This pilot study aimed to investigate the effects of yoga and transcendental meditation on retinal microcirculation in cardiac patients before (admission), after (discharge), and following (3 weeks after discharge) rehabilitation. Methods: This study examined changes in retinal microcirculation in three rehabilitation groups of patients after heart surgery. The control group received standard exercise therapy, while the meditation group incorporated 20 min of meditation, and the yoga group incorporated 20 min of yoga practice, twice per day for the duration of four weeks of rehabilitation. Retinal images were captured using a non-mydriatic digital retinal camera (Canon CR-2, Canon Medical Systems Europe B.V., Netherlands), and the microcirculation parameters central retinal artery equivalent, central retinal vein equivalent, and artery-to-vein ratio were analyzed using MONA REVA software ((version 2.1.1), VITO, Mol, Belgium). Repeated measures ANOVA was performed to evaluate differences between the three groups in the course of rehabilitation. Results: None of the parameters revealed significant differences in retinal microcirculation between the three rehabilitation groups. Conclusions: The study evaluating changes in retinal microcirculation, as an indicator of central circulation in cardiac patients undergoing rehabilitation, did not observe any significant changes. As yoga and meditation are underestimated approaches in cardiac rehabilitation, this pilot study acts as a basis for providing preliminary information for future studies to encourage the research community to fill the gap in this area.

Modern economies are progressively acknowledging the need to assess environmental, social, and corporate governance (ESG) elements to identify possible risks and possibilities. The financial sector, exerting significant influence over the economy, is essential for sustaining economic stability via the lending mechanism. Our study focuses on examining the influence of ESG factors on the financial stability of European financial institutions. To attain this goal, we utilized fixed-effects and random-effects dynamic panel models, analyzing 352 financial institutions across many European nations from 2019 to 2021. The study’s findings reveal a complex scenario. The findings indicate that ethical and corporate responsibility practices significantly impact the financial performance of European financial institutions. Nonetheless, the execution of policies pertaining to ESG ethics seems markedly inadequate. Our research reveals substantial evidence of a direct correlation between ethical practices and profit stability, diverging from other studies. This newly established group directly influences the financial performance of financial institutions in Europe. These findings enhance the comprehension of the interaction between ESG variables and financial stability, illuminating both the beneficial effects and the current deficiencies in ethical behaviors within the European banking sector.

The QBS-ar, based on the study of microarthropod community structure, is well known as a quick and low-cost indicator to monitor soil biological quality at the farm scale. Temperature fluctuations and other climate factors in European countries may indirectly influence soil microarthropod communities by altering resource availability and microhabitat conditions. In the context of the climate crisis, along with drought and erosion threats, especially in southern Europe, it is essential to define the limits and advantages of the QBS-ar index. We applied the QBS-ar index along a warm temperature gradient at three long-term experimental sites. Our results underlined that the QBS-ar is very sensitive for detecting soil quality and treatment effects. The results suggest that the choice of sampling season is a particularly vulnerable phase, especially for southern Mediterranean sites. Air temperature and cumulative precipitation, even in the months prior to sampling, are critical factors to consider when applying the QBS-ar index in European countries. Drought periods can negatively influence the results for soil microarthropod relative abundance; however, the presence of biological forms seems to provide useful information about the effects of treatments on soil quality. This paper lays the groundwork for scaled-up QBS-ar applications considering soils and several environmental characteristics of agroecosystems in Europe. The work can contribute to the development of applications of the index, facilitating and improving the monitoring of soil biology at the field scale. Furthermore, this study can open future perspectives for the application of QBS-ar on a larger scale thanks to the implementation and updating of an open-source database. Full article

In the 1980s, Poland was a medium-endemic country, with one of the highest incidences of hepatitis B in Europe (45/105 inhabitants). Pursuant to the WHO guidelines, obligatory vaccination was introduced in 1994–1996 (as a part of hepatitis B prophylaxis for newborns), and in 2000–2011, all 14-year-olds were vaccinated. To prevent transfusion-transmitted HBV infection (TT-HBV), since the 1970s, each donation has been tested for HBsAg and, since 2005, additionally for the presence of HBV DNA. Based on the data from the Blood Transfusion Centers, changes in HBV detection in Polish blood donors were analyzed, starting from the introduction of mandatory NAT screening until 2019. During the period under analysis, a total of 11,625 HBV-infected donors were identified: 97.95% were seropositive (confirmed HBsAg) and 2.05% were seronegative (NAT yields). The detection frequency for both categories of infections was significantly (p = 0.05) higher for men than for women (Residual Risk RR = 1.4 and RR = 2.63, respectively). Seropositive infections were detected more frequently (p < 0.05) in first-time donors than in repeat donors (RR = 360), while no significant differences were observed in the category of seronegative infections. A downward trend in HBsAg detection was observed in both first-time and repeat donors (Spearman’s coefficient R = −0.98 and R = −0.90, respectively). The frequency of HBsAg in first-time donors decreased 5-fold, and, in repeat donors, 30-fold. In both subpopulations, the largest decrease occurred in the age group ≤ 20 years (i.e., donors born between 1985 and 2001). The incidence of window period (WP) infections in the repeat donor group demonstrated a downward trend (R = −0.54, p < 0.05), and in the first-time donor group, no significant trend was recorded. For occult hepatitis B infection (OBI), no significant trend was observed in either donor subpopulation. WP infections were detected significantly more often in donors aged 21–50 years than in donors ≤20 years, most often in the 41–50 age group. The frequency of OBI increased with donor age and was the highest in the 51–60 age group. A spectacular decrease in the frequency of HBsAg(+) infections was observed in current study, indicating the effectiveness of the hepatitis prevention strategy applied in Poland. We expect that the improvement in the epidemiological situation among blood donors causes a reduction in the risk of TT-HBV. Confirmation of this hypothesis by the analysis of residual risk should be a subject of further studies. Full article

Pedunculate oak (Quercus robur L.) is widely distributed across Europe and serves critical ecological, economic, and recreational functions. Investigating its responses to stressors such as drought, extreme temperatures, pests, and pathogens provides valuable insights into its capacity to adapt to climate change. Genetic and dendrochronological studies offer complementary perspectives on this adaptability. Tree-ring analysis (dendrochronology) reveals how Q. robur has historically responded to environmental stressors, linking growth patterns to specific conditions such as drought or temperature extremes. By examining tree-ring width, density, and dynamics, researchers can identify periods of growth suppression or enhancement and predict forest responses to future climatic events. Genetic studies further complement this by uncovering adaptive genetic diversity and inheritance patterns. Identifying genetic markers associated with stress tolerance enables forest managers to prioritize the conservation of populations with higher adaptive potential. These insights can guide reforestation efforts and support the development of climate-resilient oak populations. By integrating genetic and dendrochronological data, researchers gain a holistic understanding of Q. robur’s mechanisms of resilience. This knowledge is vital for adaptive forest management and sustainable planning in the face of environmental challenges, ultimately helping to ensure the long-term viability of oak populations and their ecosystems. The topics covered in this review are very broad. We tried to include the most relevant, important, and significant studies, but focused mainly on the relatively recent Eastern European studies because they include the most of the species’ area. However, although more than 270 published works have been cited in this review, we have, of course, missed some published studies. We apologize in advance to authors of those relevant works that have not been cited. Full article

Stand-alone carbon pricing is still predominantly advanced as the policy instrument of choice for abating greenhouse gas emissions, although it has enjoyed limited support in practice. Against this background, the current paper investigates whether combinations of climate policy measures constitute a promising avenue for reaching zero emissions in the power, transport, buildings, and industry sectors. Adopting a sectoral approach, we review the international literature on instrument mixes and consolidate previous findings according to four widely employed evaluation criteria, namely environmental effectiveness, economic efficiency, social equity, and political feasibility. The performance of mixes along these dimensions is critically assessed by studying the inter-relationships between decarbonisation levers, decarbonisation barriers, and policy instrument characteristics. Our analysis suggests that carefully designed combinations of measures may perform better than stand-alone instruments in many instances, although trade-offs between policy objectives are inevitable. We show evidence that desirable instrument mixes should be tailored to the characteristics of targeted agents and technologies, but argue that some level of carbon pricing typically offers high potential for synergies with complementary measures in all sectors. The study focuses on Switzerland for illustrative purposes, yet the policy implications are far-reaching and drawn from experiences across Europe and North America. Full article

The Internet of Things (IoT) is expanding rapidly, but the security of IoT devices remains a noteworthy concern due to resource limitations and existing security conventions. This research investigates and proposes the use of a Light certificate with the Constrained Application Protocol (CoAP) instead of the X509 certificate based on traditional PKI/CA. We start by analyzing the impediments of current CoAP security over DTLS with the certificate mode based on CA root in the constrained IoT device and suggest the implementation of LightCert4IoT for CoAP over DTLS. The paper also describes a new modified handshake protocol in DTLS applied for IoT devices and Application server certificate authentication verification by relying on a blockchain without the complication of the signed certificate and certificate chain. This approach streamlines the DTLS handshake process and reduces cryptographic overhead, making it particularly suitable for resource-constrained environments. Our proposed solution leverages blockchain to reinforce IoT gadget security through immutable device characters, secure device registration, and data integrity. The LightCert4IoT is smaller in size and requires less power consumption. Continuous research and advancement are pivotal to balancing security and effectiveness. This paper examines security challenges and demonstrates the effectiveness of giving potential solutions, guaranteeing the security of IoT networks by applying LightCert4IoT and using the CoAP over DTLS with a new security mode based on blockchain.

Canning extends the shelf life of seafood products while preserving their quality. It is increasingly considered a more sustainable food processing method due to the primary fishing methods used for key species and the lower energy costs compared to the production of fresh and frozen fish. However, canning can change key components, allow some contaminants to persist, and generate undesirable compounds. This review revisits the effects of canning on product quality and highlights the potential hazards that may compromise safety. It also examines emerging trends in product development, particularly novel formulations aimed at optimizing nutritional value while maintaining safety standards without compromising sustainability. Overall, the quality of most canned seafood meets industry requirements, for example, with improvements in processing strategies and strict safety protocols, leading to reduced histamine levels. However, data on marine biotoxins and microplastics in canned seafood remain limited, calling for more research and monitoring. Environmental contaminants, along with those generated during processing, are generally found to be within acceptable limits. Product recalls related to these contaminants in Europe are scarce, but continuous monitoring and regulatory enforcement remain essential. While new formulations of canned fish show promise, they require thorough evaluation to ensure both nutritional value and safety. Full article

Understanding the past dynamics of vegetation in response to climate change is crucial for predicting future ecological outcomes. This study has two primary objectives: (1) to reconstruct the vegetation history of the coastal region around Lake Lilaste in Central Latvia during the Holocene and (2) to assess the impacts of climate change on forest composition through the analysis of pollen data and radiocarbon dating. The results indicate that dominant tree species, particularly pine (Pinus), have shown remarkable resilience despite significant climate fluctuations. Pine’s adaptation to the sandy, mineral-poor soils surrounding the lake likely underpins its sustained dominance, while the influence of climate change on overall tree biomass is more notable. Our results suggest that vegetation may be more susceptible to future climate variability, yet the region’s geological and soil conditions continue to favor pine, birch (Betula), and alder (Alnus) populations. While human activities have influenced the region during the last millennia, their impact has been more pronounced in areas further from the lake. This study underlines the importance of long-term forest dynamics and emphasizes that the soil and geological and geographical setting must be considered for climate change assessments. Full article

Food security in Europe remains assured, but at too high an environmental cost. The old agro-chemical model has proven inadequate to meet the multi-faceted challenges of the 21st century. The most promising model must be sustainable and simultaneously improve economic performance, environmental protection, and social impact. Agro-ecology meets those goals, but its implementation would require a complete rethinking of EU policies for agriculture and food. The Common Agricultural Policy must radically change from quantitative to qualitative support and favour a demand-led rather than a supply-led approach to reflect consumer needs, not only in food pricing terms but also in nutritional and health aspects.

Background/Objectives: Studies on executive functions in child sex offenders relate their findings to the presence of pedophilia, but they are not able to distinguish between paraphilia and abuse. It is therefore this lack of a distinction that leads us to complement the existing information. Thus, the purpose of this review is to find all available evidence on the neurocognitive and neuroanatomical differences in executive functions among pedophilic and non-pedophilic child sex offenders, and non-offender pedophiles. Methods: The present review, in accordance with the PRISMA statement, ran a systematic search of three databases (Web of Science, Scopus and ProQuest). This search identified 5697 potential articles, but only 16 studies met all the inclusion criteria. Most of the studies were conducted in Europe, using a cross-sectional design with a convenience sample. Results: The results showed alterations in frontal, temporal and parietal structures related to executive functions (e.g., response inhibition) in child sexual offenders, regardless of the presence of pedophilia. Conclusions: In summary, there are differences in brain structure underlying executive functions related to child sexual abuse, but not to pedophilia as such. Full article
