Background/Objectives: Improvements in depression and anxiety, associated with moderate increases in physical activity, might induce reductions in emotional eating, especially in women with obesity, where emotion-driven eating is highly problematic. This pilot, field-based study sought to assess whether physical activity increase, itself, primarily predicts improved mood (biochemical theories) or if psychosocial factors associated with cognitive–behavioral treatment are principal correlates (behavioral theories). An aim was to inform improved treatment processes. Methods: Women with obesity participated in 6-month community-based behavioral obesity treatments emphasizing either: (a) standard education in weight-reduction methods (n = 28), (b) eating-related self-regulation methods (n = 24), or (c) self-regulation + relaxation training (n = 24). They completed a series of behavioral and psychological self-reports at baseline and Months 3 and 6. Results: Findings confirmed no significant difference in 3-month increases in physical activity, by group. There were significantly greater overall improvements in depression, emotional eating, self-regulation, and self-efficacy across the two self-regulation-focused groups (ps < 0.02), with anxiety improvement not reaching significance (p = 0.055). Separate significant paths from 3-month changes in depression and anxiety → self-efficacy change → emotional eating change were found. The same significant path was detected emanating from 6-month anxiety change; however, the hypothesized path of 6-month changes in depression → self-regulation → self-efficacy → emotional eating was, rather, significant. Weight reduction was considerably greater in the two self-regulation-based groups (~6% reduction), with simultaneously entered changes in self-regulation and self-efficacy significant predictors of those weight changes. Conclusions: Findings suggested viability in behavioral theory-driven explanations of the physical activity-mood improvement relationship. Future treatment foci on self-regulatory skills development leading to improvements in eating-related self-efficacy, emotional eating, and weight were suggested to extend the findings of this pilot study.

More than 50 years ago, children were viewed as naturally resilient and often labeled invulnerable or invincible. Resilience is now understood to be the result of dynamic interactions between individual, familial, social, and environmental systems, decentralizing the focus from the individual to the global society. Experiences with adversity may emanate from the youth’s family environment, their community, the school system, and larger structural challenges related to poverty, discrimination, health disparities, and educational inequities. Youth experiences with adversity, trauma, and tragedy have the potential to negatively impact youth well-being, with consequences manifesting across the lifespan. Children and adolescents generally hold limited power to change their circumstances and are often ill-equipped to resolve the adverse or traumatic experiences occurring within their ecosystem. The value of social supports in the young person’s ability to be resilient has been affirmed. This understanding is particularly important for children growing up in poverty or in Low- and Middle-Income Countries (LMICs) where significant challenges occur as a result of economic and social disadvantage. Resilience at the individual level is unlikely to eliminate macrolevel issues. Developing and deploying strategies to enhance the ability of youth to rebound from adversity represents a positive step at the micro level, but the larger issues of economic and social disadvantage are unlikely to change without macro-level interventions. Glancing toward the future, traumatized youth may grow into traumatized adults without appropriate interventions and changes in social policies, programs, and protections. Full article

Monitoring soil moisture (SM) using permanently installed gamma radiation (GR) detectors is a promising non-invasive method based on the inverse relationship between SM and soil-emitted GR. In a previous study, we successfully estimated SM from environmental gamma radiation (EGR) measured by a low-cost counter-tube detector. Since this detector type provides a bulk GR response across a wide energy range, EGR signals are influenced by several confounding factors, e.g., soil radon emanation, biomass. To what extent these confounding factors deteriorate the accuracy of SM estimates obtained from EGR is not fully understood. Therefore, the aim of this study was to compare the accuracy of SM estimates from EGR with those from reference ⁴⁰K GR (1460 keV) measurements which are much less influenced by these factors. For this, a Geiger–Mueller counter (G–M), which is commonly used for EGR monitoring, and a gamma spectrometer were installed side by side in an agricultural field equipped with in situ sensors to measure reference SM and a meteorological station. The EGR_G–M and spectrometry-based ⁴⁰K measurements were related to reference SM using a functional relationship derived from theory. We found that daily SM can be predicted with an RMSE of 3.39 vol. % from ⁴⁰K using the theoretical value of α = 1.11 obtained from the effective ratio of GR mass attenuation coefficients for the water and solid phase. A lower accuracy was achieved for the EGR_G–M measurements (RMSE = 6.90 vol. %). Wavelet coherence analysis revealed that the EGR_G–M measurements were influenced by radon-induced noise in winter. Additionally, biomass shielding had a stronger impact on EGR_G–M than on ⁴⁰K GR estimates of SM during summer. In summary, our study provides a better understanding on the lower prediction accuracy of EGR_G–M and suggests that correcting for biomass can improve SM estimation from the bulk EGR data of operational radioactivity monitoring networks.

Araucaria araucana is one of the longest-living Chilean trees. Recently, Araucaria Leaf Damage disease, which causes damage to branches and crowns, was detected. Sinophloeus porteri, a bark beetle affecting A. araucana, could be associated with foliar damage. However, little is known about their ecological and chemical interactions. This study examined the olfactory response of S. porteri to volatiles emitted from A. araucana. Branches and weevils were collected from a national park, and volatiles were trapped from both healthy and unhealthy branches. Thirty terpenes were identified, some of which were reported for the first time in A. araucana. Healthy branches emitted large amounts of myrcene (>360 ng g⁻¹ day⁻¹), and unhealthy branches showed high hibaene emanations (>140 ng g⁻¹ day⁻¹). Olfactory assays verified that S. porteri was attracted to the volatile blends of branches, regardless of the health condition of the branches, but preferred the blend of unhealthy branches. Moreover, myrcene was repellent to these weevils, and hibaene acted as an attractant, suggesting that A. araucana might use myrcene for defense against S. porteri, and hibaene could stimulate host selection by beetles.

The study of neuronal electrical activity and spatial organization is essential for uncovering the mechanisms that regulate neuronal electrophysiology and function. Mathematical models have been utilized to analyze the structural properties of neuronal networks, predict connectivity patterns, and examine how morphological changes impact neural network function. In this study, we aimed to explore the role of the actin cytoskeleton in neuronal signaling via primary cilia and to elucidate the role of the actin network in conjunction with neuronal electrical activity in shaping spatial neuronal formation and organization, as demonstrated by relevant mathematical models. Our proposed model is based on the polygamma function, a mathematical application of ramification, and a geometrical definition of the actin cytoskeleton via complex numbers, ring polynomials, homogeneous polynomials, characteristic polynomials, gradients, the Dirac delta function, the vector Laplacian, the Goldman equation, and the Lie bracket of vector fields. We were able to reflect the effects of neuronal electrical activity, as modeled by the Van der Pol equation in combination with the actin cytoskeleton, on neuronal morphology in a 2D model. In the next step, we converted the 2D model into a 3D model of neuronal electrical activity, known as a core-shell model, in which our generated membrane potential is compatible with the neuronal membrane potential (in millivolts, mV). The generated neurons can grow and develop like an organoid brain based on the developed mathematical equations. Furthermore, we mathematically introduced the signal transduction of primary cilia in neurons. Additionally, we proposed a geometrical model of the neuronal branching pattern, which we described as ramification, that could serve as an alternative mathematical explanation for the branching pattern emanating from the neuronal soma. In conclusion, we highlighted the relationship between the actin cytoskeleton and the signaling processes of primary cilia. We also developed a 3D model that integrates the geometric organization unique to neurons, which contains soma and branches, such that the mathematical model represents the interaction between the actin cytoskeleton and neuronal electrical activity in generating action potentials. Next, we could generalize the model into a cluster of neurons, similar to an organoid brain model. This mathematical framework offers promising applications in artificial intelligence and advancements in neural networks. Full article

Burnout and work-related stress are extensively studied among mental health professionals (MHPs) in countries around the world, but there is a paucity of research emanating from Greece’s hybrid healthcare system. In Greece, MHPs may encounter unique challenges with economic obstacles and in putting ongoing community-oriented mental healthcare policies into practice. This study aims, first, to assess the prevalence of burnout, compassion fatigue, and compassion satisfaction among Greek MHPs; and second, to examine the sociodemographic and work-related factors influencing these dimensions of professional quality of life. A total of 287 Greek MHPs (25.4% male, 74.6% female; M = 39.85 years, SD = 9.52) completed the Maslach Burnout Inventory (MBI) and the Professional Quality of Life Scale-5 (ProQOL-5). Sociodemographic and occupational data were also collected. Findings revealed that 11.8% of participants reported high emotional exhaustion, 19.9% high depersonalization, and 35.9% a high risk of reduced personal accomplishment. Almost half of the participants (48.8%) reported high levels of compassion satisfaction, suggesting that many MHPs continue to find fulfillment in their work. Notably, none of the participants reported high levels of compassion fatigue. Sociodemographic characteristics, such as gender, ethnicity, and marital status, as well as work-related factors, including employment sector, specialization, and years of experience, were related to MHPs’ professional quality of life. These results highlight the need for targeted strategies to address burnout and promote positive professional experiences among MHPs in Greece. Interventions should support well-being and enhance the rewarding aspects of mental health practice. Full article

The creative city concept has gained global recognition, notably through the UNESCO Creative Cities Network (UCCN). In Japan, facing declining birth rates and economic stagnation, this framework was seen as a revitalization tool to increase the urban quality. Yet, while the creative city concept clearly appears on the theoretical level, its operationalization usually remains unclear. Additionally, previous research considers sustainability questions through economic, social, and cultural lenses but more rarely through environmental aspects. Thus, this paper aims to explore the implementation of the creative city in Japan, unveil the specific elements composing the policies of UNESCO Creative Cities, and question how environmental sustainability is addressed in these policies. The research method includes a qualitative analysis of the membership monitoring reports (MMRs) submitted by cities to UNESCO. Conducting a field survey in a creative facility and a hearing survey with the city government, the research also focuses on Kanazawa as a case study to explore in greater depth the interaction between creative city strategies and environmental sustainability. Among the research findings, economic perspectives—through support for creative industries and the promotion of tourism—and systematic actions targeting children dominate the MMRs, while socio-environmental aspects receive less attention. Most ambitious initiatives toward environmental sustainability were implemented in rural cities. In Kanazawa, it appears the creative city policy is independent of the local environmental policies, although some opportunities exist to connect them. The field survey indeed reveals that some spontaneous initiatives toward environmental sustainability might emanate from a creative facility. Therefore, the paper provides significance in unveiling the specific content of creative city policies in Japan and in re-examining the notion of creativity to integrate environmental sustainability into the creative city agenda.

Although lagoons are sites of water accumulation and runoff where a variety of animal species and plant varieties inhabit, they have also been positioned as spaces where rituals and religious practices take place, from which the transmission of knowledge emanates, and social activities are strengthened. The Laguna de Cajititlán (Cajititlán Lagoon) in the town of Tlajomulco de Zúñiga, Jalisco, México is a lacustrine landscape that faces a state of fragility due to incessant processes of urbanization along with basin desiccation and wastewater pollution. However, the community of Cajititlán has managed to protect its lacustrine landscape through the rescue of the religious tradition of the Procesión Los Santos Reyes (Procession of the Wise Men). Therefore, the objective of this article is to analyze how this tradition, as cultural heritage, has influenced the conservation of the lacustrine landscape. We conclude that cultural heritage and the lacustrine landscape are bidirectionally correlated because fostering Indigenous traditions like the Procesión in Cajititlán, as a manifestation of devotion and faith, enhances identity, promotes tourism, and supports conservation practices and the sustainability of the lacustrine landscape. At the same time, conservation of the lacustrine landscape enables the preservation of cultural heritage, generating an interdependent relationship between these elements. Full article

An integrated approach is sorely needed to treat biogas emanating from anaerobic digesters (AD) which is cost-effective, in terms of upgrade/purification to ~95–98% methane needed for pipeline injection. This is a very pressing environmental and waste-management problem. At present, biogas water-/solvent-washing operations require significant capital investment, with high operational and maintenance costs. In the present study, we deployed a facile and efficient novel nanobubble-formation approach using applied electric fields to boost biogas-enrichment operations: we achieve substantial methane enrichment via selective CO₂ and H₂S take-up in water in the form of nanobubbles. This enables an integrated waste-processing vision using cutting-edge engineering-science advances, and making anaerobic digestion a circular-economic and practical reality, that can be deployed at scale—initially developing at the small scale—and points the way for low-energy CO₂ capture in the form of nanobubbles by dint of the electric-field approach. In addition, we carried out nanobubble generation using various gases for water treatment for both up- and down-stream sludge-containing (waste)water, achieving meaningful operational successes in AD operations and organic-fertiliser production, respectively.

This study investigates, both experimentally and theoretically, the impact of incorporating window shutters on the thermal resistance of double-glazed window units, employing computational fluid dynamics (CFD) modelling. The integration of shutters, whether installed internally or externally, introduces an additional air layer that significantly influences heat transfer between indoor and outdoor environments. This effect on the thermal performance of the transparent structure was analysed through experimental measurements under real operating conditions and numerical simulations involving fluid dynamics and energy equations for the air gaps, alongside heat conduction equations for the solid components. Fourth-kind boundary conditions, considering both radiative and conductive components of the total heat flux emanating from the building’s interior, were applied at the solid–gas interfaces. The simulation results, comparing heat transfer through double-glazed windows with and without shutters, demonstrate a substantial increase in thermal resistance, ranging from 2 to 2.5 times, upon shutter implementation. These findings underscore the effectiveness of employing shutters as a strategy to enhance the energy efficiency of windows and, consequently, the overall energy performance of buildings. This research contributes to the advancement of sustainable materials for engineering applications by providing insights into the optimisation of thermal performance in building envelopes.

(1) Background: As the demand for ²¹²Pb for clinical theranostics rises, empirical studies that examine the radiation safety implications of different ²²⁴Ra sources are needed to facilitate discussions with local authorities for the translation of ^203/212Pb theranostics routine clinical practice. (2) Methods: Environmental ²²⁰Rn (Thoron) emanation was detected by a RAD7 detector in the vicinity of respective ²¹²Pb sources and additional alpha-dosimeters to detect ²²⁰Rn during generator elution, radiosynthesis, and quality control. Personnel gamma exposure was measured using whole-body and ring dosimeters. Generators included those based on wet-chemical-process- and emanation-based technology. (3) Results: During generator handling, varying levels of ²²⁰Rn were observed in the vicinity of generators. An additional monthly whole-body dose must be considered when handling different sources of ²¹²Pb generators, and this depends upon local shielding and the handling approaches toward use of the technology. (4) Conclusions: ²²⁴Ra in any form (including radionuclide generators) should always be handled within a fume hood to keep potential contamination and exposure to personnel as low as reasonably achievable. Following standard practices of radiation safety, generators of ²¹²Pb can be used safely for theranostic applications. Full article

In this article, I begin with the topic of “circulations”, conducting a comparative analysis of the similarities and differences in Emerson’s and Zhuangzi’s philosophies regarding “circulations” as the mode of cosmic generation and operation, as well as the relationship between “circulations” and self-transcendence. Furthermore, I explore the practical paths to achieve self-transcendence via circulations based on these two aspects. Specifically, both Emerson and Zhuangzi regard “circulations” as the fundamental way of cosmic generation and operation. However, Emerson emphasizes the directionality of “circulations”, where God generates all things through “emanation”, and all things return to God through “ascent”. In contrast, Zhuangzi emphasizes the characteristics of the Dao in generating all things, including its “cyclic repetition” (xun huan wang fu 循环往复) and “creating myriad forms” (zhi qi wan shu 制器万殊). The “Dao” that generates these “circulations” itself does not possess morality or divinity. Both of them believe that individuals can achieve self-transcendence by aligning with “circulations”. Regarding the specific practical paths, Emerson suggests that we can return to God through revelation, specifically via nature, poets, art, and vocation. On the other hand, Zhuangzi believes that we can achieve unity with the Dao by “following the Dao”, specifically through the life-nurturing method of “following the Du as a principle” (yuan du yi wei jing 缘督以为经) and the spiritual cultivation methods of “emptiness of mind-heart and selflessness” (xinzhai 心斋) and “sitting in oblivion” (zuowang 坐忘).

The underreporting of gender-based violence (GBV) in institutions of higher learning can be attributed to a range of causes and has an impact on students’ physical and mental health. Institutions of higher learning have made efforts to eradicate the problem, yet incidences are still on the rise, calling for urgent attention. This paper focuses on the causes of the underreporting of GBV in higher education institutions (HEIs) as a point of reference to understanding the root magnitude of the pandemic in order to devise problem-specific interventions to eradicate GBV in institutions of higher learning. The rational choice theory and cultural acceptance of violence theory guided the analysis of the findings discussed in this paper. The rational choice theory provides insights into why victims choose not to report their victimization. The cultural acceptance of violence theory highlights how cultural norms can normalize and perpetuate GBV, creating barriers for victims to come forward. The findings discussed in this paper emanate from a qualitative study that gathered data using 22 one-on-one interviews with students and one focus group comprising seven supporting staff members from the University of Umvoti. Data were thematically analyzed to address the research objectives. The findings indicate that intimidation and distrust in law enforcement agents and institutions are the main reasons why GBV is underreported. Other factors that may be at play include fear of the perpetrator taking revenge, fear of not being believed, stigma and shame, the patriarchy, reliance on money, and a lack of awareness about GBV. To address these issues, this paper recommends that higher education institutions should uphold the principles of justice, fairness, and transparency in handling GBV cases. Moreover, there should be ongoing facilitation of awareness campaigns on GBV covering issues of consent, gender equality, safety, and reporting and support. When victims of GBV feel supported, they are more likely to trust the institution and report any victimization. Full article

The interaction of the Almone River with groundwater in the Caffarella area (Rome, Italy) was investigated using a multi-method approach based on hydrogeological and radon analyses. Eleven measurement stations were established along the river at distances of approximately 270 m from one another. Stream discharge, water physicochemical properties, and radon levels were measured from June 2024 to March 2025. The contribution of two tributaries of the Almone was evaluated, but it was found to be negligible in terms of radon contribution. Except for an average increase of 40 L/s between stations 1A and 2A, the Almone’s discharge (corrected for the streams input) was constant (around 150 L/s) in June and slightly increasing from 6A to 11A in March due to heavier rainfalls. The increased discharge between stations 1A and 2A was interpreted as groundwater overflow from the volcanic aquifer into the alluvial body and in turn into the river due to a change in geometry and volume of the volcanic aquifer. In that part of the river, radon concentration increased only in March, due to the fast transition of the groundwater from a high to a lower radon emanation unit. Radon decreased along the valley due to atmospheric evasion, as confirmed by pH growth due to CO₂ degassing. Full article

Shockwaves induce considerable flow separation loss; it is essential to reduce this using the flow control method. In this manuscript, a method for suppressing flow separation in turbomachinery through a constant adverse-pressure gradient was investigated. The first-passage shock was split into a compression wave system of the vane suction surface. The aim of this was to reduce loss from shockwave/boundary layer interactions (SWBLIs). This method promotes the performance parameters of the supersonic compressor cascade. The investigation targets were a baseline cascade and the improved system. Both cascades were numerically studied with the aid of the Reynolds-averaged Navier–Stokes (RANS) method. The simulation results of the baseline cascade were also validated through experimentation, and a further physical flow analysis of the two cascades was conducted. The results show that the first-passage shockwave was a foot above the initial suction surface, with a weaker incident shock along with a clustering of the compression wave corresponding to the modified cascade. It was also concluded that the first-passage shockwave foot of the baseline cascade was replaced with a weak incident shock, and a series of compression waves emanated from the adopted negative-curvature profile. The shock-induced boundary layer separation bubble disappeared, and much smaller boundary layer shape factors over the SWBLI region were obtained for the improved cascade compared to the baseline cascade. This improvement led to a high level of stability in the boundary layer state. Sensitivity analyses were performed through different simulations on both cascades, unveiling that the loss in total pressure was lower in the case of the updated cascade as compared to the baseline.
