Conceptual Model of Permafrost Degradation in an Inuit Archaeological Context (Dog Island, Labrador): A Geophysical Approach

Characterizing permafrost is crucial for understanding the fate of arctic and subarctic archaeological archives under climate change. The loss of bio-physical integrity of archaeological sites in northern regions is still poorly documented, even though discontinuous permafrost is particularly vulnerable to global warming. In this study, we documented the spatial distribution of the permafrost-supported Inuit archaeological site Oakes Bay 1 on Dog Island (Labrador, Canada) while employing a novel approach in northern geoarchaeology based on non-invasive geophysical methods. ERT and GPR were successfully used to estimate active layer thickness and image permafrost spatial variability and characteristics. The results made it possible to reconstruct a conceptual model of the current geocryological context of the subsurface in relation to the site topography, hydrology, and geomorphology. The peripherical walls of Inuit semi-subterranean sod houses were found to contain ice-rich permafrost, whereas their central depressions were identified as sources of vertical permafrost degradation. The geophysical investigations were used to classify the permafrost at Oakes Bay 1 as climate-driven, ecosystem-protected permafrost that cannot regenerate under current climate conditions. This work highlights how the permafrost at Oakes Bay 1 is currently affected by multi-point thermal degradation by both conduction and advection, which makes it highly sensitive to climate warming.

Addressing Ethical Concerns in Implementing Mindfulness-Based Interventions in Educational Setting

AbstractThe burgeoning interest in mindfulness and the way it has been stripped from its Buddhist ontological roots and popularized in the West has recently raised ethical concerns regarding its application in various domains, and more specifically in the educational field. We will address in this article three main ethical concerns regarding implementing mindfulness-based interventions (MBIs) in the educational field. Firstly, how do we help educators and students cultivate personal awareness while at the same time being conscious of the needs of others and promote a pro-social orientation? Secondly, how do we ethically implement MBIs in the current neoliberal social, cultural, and political context? Thirdly, how do we implement MBIs in a culturally sensitive manner respecting the ethics of other ethnic groups and other societies? We will attempt to offer solutions to those issues by exemplifying how MBIs are integrated with compassion-based interventions (e.g., mindful self-compassion (MSC)) and social-emotional learning (understanding and managing emotions, building positive relationships, and making responsible decisions) among educators and students in Jewish and Arab schools in Israel. We will discuss three MBI programs that incorporate strategies addressing social ailments such as stereotyping and prejudicial attitudes and promote pro-social behavior as well as share research findings regarding their efficacy. Additionally, we will outline ways in which these mindfulness-based programs were adapted to suit different populations. Finally, we will conclude by pointing to future means to address these issues.

Telemedicine for patients with facial palsy : Current developments and options in otorhinolaryngologic treatment

Digitalization is also becoming increasingly important in medicine. The COVID-19 pandemic has further accelerated this process and politicians are trying to create aframework for successful knowledge transfer and better digital medical care. This article describes the role of telemedicine in the treatment of patients suffering from facial nerve palsy. Facial nerve palsy has awide range of effects, from limitations in facial mobility to psychological sequelae. While many of the acute, idiopathic facial nerve palsies improve after afew weeks, around athird of those affected develop synkinesis, involuntary movements that have lifelong functional and psychological consequences. Treatment includes various modalities, from medication and surgery to movement training. Telemedicine offers innovative solutions in cases of regional underuse, but also in the treatment of chronic facial nerve palsies. The article defines the term "telemedicine" in the current context and presents different types of application. Adetailed analysis of the application scenarios of telemedicine in facial nerve palsy patients shows that despite alack of evidence, many potentially useful concepts exist.

ROOTS AND WINGS - CULTURAL AWARENESS AND PERSONAL DEVELOPMENT PROGRAM FOR CHILDREN

In the current context, cultural education plays an essential role in the integral development of children, especially in rural communities where access to cultural resources may be limited. This article examines the "Roots and Wings" program, an innovative project designed to enrich the cultural education of rural children through direct and experiential activities. Through storytelling and folklore workshops, cultural preservation projects, local art and history sessions, children's festivals and partnerships with schools, the program aims to strengthen children's ties with the cultural heritage of their community. The study uses mixed methods, including participatory observations and questionnaires, to assess the impact of the program on children's knowledge, appreciation and application of cultural values in everyday life. Preliminary results suggest a significant improvement in understanding and appreciation of local culture, as well as an increase in confidence in one's own creative and social skills. The article argues that such programs can serve as valuable models for integrating culture into the educational curriculum, having the potential to transform children's perspective on cultural heritage and positively influence their behavior.

Blood lead levels in an endangered vulture decline following changes in hunting activity

Lead ammunition stands out as one of the most pervasive pollutants affecting wildlife. Its impact on bird populations have spurred efforts for the phase-out of leaded gunshot in several countries, although with varying scopes and applications. Ongoing and future policy changes require data to assess the effectiveness of adopted measures, particularly in the current context of biodiversity loss. Here, we assessed the long-term changes in blood lead (Pb) levels of Egyptian vultures from the Canary Islands, Spain, which have been severely affected by Pb poisoning over the past two decades. During this period, the reduction in hunting pressure and changes in legislation regarding firearms usage for small game hunting likely contributed to a decrease in environmental Pb availability. As anticipated, our results show a reduction in Pb levels, especially after the ban on wild rabbit hunting with shotgun since 2010. This effect was stronger in the preadult fraction of the vulture population. However, we still observed elevated blood Pb levels above the background and clinical thresholds in 5.6% and 1.5% of individuals, respectively. Our results highlight the positive impact of reducing the availability of Pb from ammunition sources on individual health. Nonetheless, the continued use of Pb gunshot remains an important source of poisoning, even lethal, mainly affecting adult individuals. This poses a particular concern for long-lived birds, compounding by potential chronic effects associated with Pb bioaccumulation. Our findings align with recent studies indicating insufficient reductions in Pb levels among European birds of prey, attributed to limited policy changes and their uneven implementation. We anticipated further reductions in Pb levels among Egyptian vultures with expanded restrictions on hunting practices, including a blanket ban on Pb shot usage across all small game species.

IMPROVING SOCIAL COMPETENCES THROUGH SPORT: AN EXPLORATION OF THE EDUCATIONAL ROLE OF PHYSICAL ACTIVITY IN ADOLESCENT DEVELOPMENT

The current context of society underlines the need to develop robust social skills among adolescents, essential for social integration and professional success. This research examines the impact of physical activity and sports on the development of social skills, such as empathy, effective communication and teamwork, among adolescents. Through a mixed methodology, combining quantitative analysis of data collected from surveys applied to a sample of 500 adolescents and qualitative analysis of detailed interviews with selected participants, the study provides a comprehensive perspective on how involvement in sports activities contributes to improving social skills. The results indicate a significant positive correlation between regular participation in sports and higher levels of social skills mentioned. These findings suggest that sport, as an integral part of the educational curriculum, can play a vital role in promoting adolescent social development. The conclusions of the study recommend the systematic incorporation of physical education programs focused on the development of social competences, highlighting the importance of a holistic educational framework that values the physical, cognitive and social dimensions of youth development. This abstract effectively summarizes the purpose, methodology, main results, and conclusions of the research, giving the reader a clear and concise overview of the study. The next step would be to develop the introduction section, which will detail the context of the research and objectives in more detail. If you have any further details or adjustments to make to the abstract, or if you would like us to proceed with the introduction, please let me know.

What if there is no further south to go: Assessing the vulnerability of Nacella species to climate change

In the current context of climate change, southern South America and the Southern Ocean are undergoing profound environmental transformations that impose challenges to marine species. Shifts in species distribution ranges will occur through expansions or contractions of the range edges. Invertebrates such as Nacella spp., that being template-cold water species, will be more vulnerable to increasing temperature and will therefore suffer range contraction as temperatures increase southward. To understand the future of this sensitive group of gastropods, the potential impact of future climate on the distribution ranges of six species of the genus Nacella was studied using ensemble ecological niche models and representative concentration pathway 8.5 scenarios for the years 2050 and 2100. The results indicate that all the species studied will undergo a shift in their distribution in response to the projected changes in climate with a decline in habitat suitability. Particularly, the species will lose suitable areas mainly in the northern edge of their current distribution. Nevertheless, the species may not change their distribution equally. Our study suggests that N. magellanica, N. clypeater, and N. concinna appear to exhibit vulnerability, albeit with potentially lesser impact. Nacella magellanica is the limpet that shows the least distribution change in 2100. Both species, N. clypeater and N. concinna, will move southward while the Antarctic species will expand their distribution to other Antarctic areas. The most significant impact is expected for three Magellanic species (N. deaurata, N. flammea, and N. mytilina), currently distributed across the southern tip of South America. With restricted geographical ranges, these species face increased vulnerability to habitat loss as they cannot migrate southward. This comprehensive analysis offers invaluable insights into how Nacella species could tackle the challenges of climate change. The emphasis on specific species' vulnerabilities and the differential impacts on their distribution enhances our understanding of the potential consequences of climate change in the studied region. Furthermore, it will aid in formulating effective conservation and management strategies to protect Antarctic and sub-Antarctic ecosystems.

Stimulation of secondary metabolism in grape berry exocarps by a nature-based strategy of foliar application of polyols

In grapes under drought stress, polyols accumulate through tight coordination at the molecular level between increased membrane transport of polyols and inhibition of polyol oxidation. Here, the effects on grape metabolism of an exogenous foliar application of polyols as a potential sustainable viticultural practice to increase grapevine performance and berry quality were thoroughly assessed. Grapevines were pulverised with a polyol solution containing 2 mM mannitol and 2 mM sorbitol, and the metabolome of grape berry exocarps and important metabolic pathways associated with berry quality and polyol metabolism were analysed at véraison and mature stages. By combining metabolomics analysis using UPLC-MS, enzyme activity assays and targeted transcriptional analyses, it was demonstrated that foliar application of polyols stimulated by 3.5-fold and 6-fold abscisic acid (ABA) biosynthesis at véraison and mature grape berries, respectively. It also stimulated the concentration of anthocyanins, stilbenes and total phenolics in exocarps through the upregulation of phenylpropanoid, stilbenoid and anthocyanin biosynthetic pathways shown by increases in phenylalanine-ammonia lyase (PAL) activity (3-fold) and VviPAL1 expression, stilbene synthase 1 (VviSTS1) transcripts (ca. 5-fold), UDP-glucose:flavonoid 3-O-glucosyltransferase (UFGT) activity and VviUFGT1 expression, among other results, at the mature stage, when these changes were most noticeable. Many secondary metabolites synthesised in these pathways identified by UPLC-MS analysis were present at higher quantities in exocarps from polyol-treated plants such as fertaric acid, E-resveratrol, E-piceatannol, piceid, pallidol, E-ε-viniferin, myricetin-hexoside 1, cyanidin-3-O-glucoside and malvidin-3-O-(6-p-coumaroyl)-glucoside. Foliar application of low-concentration polyols is, therefore, a promising biostimulant-based strategy to improve grape berry quality and nutritional value in the current context of climate change.

Goal-Guided Graph Attention Network with Interactive State Refinement for Multi-Agent Trajectory Prediction.

The accurate prediction of the future trajectories of traffic participants is crucial for enhancing the safety and decision-making capabilities of autonomous vehicles. Modeling social interactions among agents and revealing the inherent relationships is crucial for accurate trajectory prediction. In this context, we propose a goal-guided and interaction-aware state refinement graph attention network (SRGAT) for multi-agent trajectory prediction. This model effectively integrates high-precision map data and dynamic traffic states and captures long-term temporal dependencies through the Transformer network. Based on these dependencies, it generates multiple potential goals and Points of Interest (POIs). Through its dual-branch, multimodal prediction approach, the model not only proposes various plausible future trajectories associated with these POIs, but also rigorously assesses the confidence levels of each trajectory. This goal-oriented strategy enables SRGAT to accurately predict the future movement trajectories of other vehicles in complex traffic scenarios. Tested on the Argoverse and nuScenes datasets, SRGAT surpasses existing algorithms in key performance metrics by adeptly integrating past trajectories and current context. This goal-guided approach not only enhances long-term prediction accuracy, but also ensures its reliability, demonstrating a significant advancement in trajectory forecasting.

‘Connective Alignment’ as the Educational Approach for Higher Education in the Digital Age

Most students in higher education at present are ‘digital natives.’ They use technology in every facet of their life, including their education. They learn from formally organised courses as well as from informal learning. Hence, informal learning has been identified as crucial for the sustainability of higher education in the current global context. Technology facilitates informal learning and, thus, has made substantial changes in how learning occurs in modern age learners. These changes that occurred in the learning process due to the influence of technology should be addressed by the educational approaches used in higher education to achieve the best outcomes in relation to the academic performance of students and students’ satisfaction. This commentary presents an educational approach: ‘Connective Alignment’ for higher education in the digital age, which can fulfil the learning needs of the learners in this digital age.

Dual generators and dual discriminators generative adversarial network for video anomaly detection

Video anomaly detection (VAD) has garnered substantial attention from researchers due to its broad applications, including fire detection, drop detection, and vibration detection. In the current context of VAD, existing methods prioritize detection efficiency but overlook the impact of motion and appearance information. Additionally, achieving accurate predictions while retaining motion and appearance information poses a significant challenge. This paper proposes a novel semi-supervised method for VAD based on Generative Adversarial Network (GAN) structures with dual generators and dual discriminators, namely Dual-GAN. The future frame generator utilizes an improved encoder-decoder network to preserve more spatial information. Motion information for the future flow generator is obtained by estimating optical flow between reconstruction frames, complementing the optical flow between prediction frames. The introduction of a frame discriminator and a motion discriminator against the frame generator enhances the realism of prediction frames, which facilitates the identification of unexpected abnormal events. This method significantly outperforms comparative approaches in synthesizing video frames and predicting future flows, showcasing its effectiveness in handling diverse video data. Extensive experiments are performed on four publicly available datasets to ensure a comprehensive evaluation of the model performance. Further exploration could include refining the model architecture, exploring additional datasets, and adapting the methodology to specific application domains.

A New Co(II)-coordination Polymer: Fluorescence Performances, Loaded with Paclitaxel-hydrogel on Breast Cancer and Molecular Docking Study.

In the current context of the increasing incidence of breast cancer, we aim to develop an efficient drug carrier for breast cancer by constructing an innovative complex consisting of a metal-organic framework (MOF) and a hydrogel. The aim of this initiative is to provide new ideas and tools for breast cancer treatment strategies through scientific research, so as to address the current challenges in breast cancer treatment. In the present study, by employment of a new Co(II)-based coordination polymer with the chemical formula of [Co(H2O)(CH3OH)L]n (1) (H2L = 5-(1H-tetrazol-5-yl)nicotinic acid) was solvothermally synthesized by reaction of Co(NO3)2·6H2O a mixed solvent of MeOH and water. The characteristics of ligand-based absorption and emission, as unveiled by ultraviolet and fluorescence spectroscopy tests, offer insights into the distinctive electronic transitions and structural features originating from the ligand in compound 1. Using natural polysaccharide hyaluronic acid (HA) and carboxymethyl chitosan (CMCS) as raw materials, HA/CMCS hydrogels were successfully prepared by chemical method and their internal morphology was studied by scanning electron microscopy. Using paclitaxel as a drug model, we further designed and synthesized a novel metal gel particle-loaded paclitaxel drug and evaluated its inhibitory effect on breast cancer cells. Finally, the hypothesized interactions between the complex and the receptor have been confirmed through molecular docking simulation, and multiple polar interactions have been verified, which further proves the potential anti-cancer capability and excellent bioactivity. Based on this, this composite material prepared from a novel Co(II)-coordinated polymer with paclitaxel hydrogel could provide a useful pathway for the identification and treatment of breast cancer.

Toward the Adaptive Reuse of Vernacular Architecture: Practices from the School of Porto

Strategies for the adaptive reuse of vernacular architecture are of utmost importance in the current context of social, economic, and environmental vulnerability. This article examines the design strategies of adaptive reuse in three cases of renowned architects of the so-called School of Porto developed across the second half of the 20th century, specifically between 1956 and 1991. The paper aims to introduce a new and deeper knowledge of the selected practices by critically documenting the whole process of the intervention (before, during, after) and not only the final result, as is common practice in specialized publications. The research methodology combines the bibliographical and archival research and interpretation of diverse graphic, photographic, and textual documentation with the production of analytical drawings. The demolitions/additions color code (black/yellow/red) is applied to plans, sections, and elevations as an essential tool for understanding and communicating the transformations undertaken. The selected case studies are Além House (1956–1967) by Fernando Távora, Alcino Cardoso House (1971–1973; 1988–1991) by Álvaro Siza, and the House in Gerês (1980–1982) by Eduardo Souto de Moura. These projects show different strategies of intervention in built heritage, providing lessons on the reactivation of obsolete or abandoned rural constructions with new functions that are compatible with the preservation of their values (historical, landscape, constructive, social, and aesthetic) and guidelines for sustainable reuse.

Relational Egalitarianism and Intergenerational Justice: Reply to Sommers

AbstractIt is often argued that relational egalitarianism has a fundamental problem with intergenerational justice when compared to other theories of justice such as utilitarianism, prioritarianism, and luck egalitarianism. Recently, Timothy Sommers argued that there is no such comparative disadvantage for relational egalitarianism. His argument is quite modest: it merely aims to reject the claim that there could be no way to extend relational egalitarianism to intergenerational justice. This may be called the ‘No Comparative Disadvantage Thesis’. The present article challenges Sommers’s argument in two ways. First, I show that Sommers fails to provide a reasonable constraint on causal efficacy, which is crucial to his argument for our relation (not relationship) to future generations. Second, I show that the chain-relatedness problem casts a shadow over Sommers’s argument for the No Comparative Disadvantage Thesis. More specifically, compared to the other theories of justice, relational egalitarianism (as it stands) can less easily justify that present persons have duties to future others. This is because relational egalitarianism cannot appeal to a specific principle in regard to the duties in question, because its principle is sensitive to current context and practice. I conclude that the No Comparative Disadvantage Thesis does not hold much promise.

Factors Affecting Sustainable Fashion Consumption: A Systematic Review and Research Orientations

Fashion is the second-largest environmental polluter globally, prompting governments, businesses, and consumers to pay more attention to sustainable fashion. Sustainable fashion is considered an environmentally friendly solution and is gradually becoming an essential trend for the future. In the current context, to promote the consumption of sustainable fashion products, governments and businesses need to delve deeper into the factors influencing consumer shopping behavior. This study analyzed 112 relevant research documents, which were selected and organized systematically. The research employed evaluation methods and synthesized materials from various continents worldwide, with a focus on Asia and Europe. Most of the collected research articles were conducted using both quantitative and qualitative methods. Additionally, the authors synthesized and observed, selecting articles that were central to the topic to provide accurate statistics and evaluations. Furthermore, this article identified gaps in the research context and proposed new directions for future studies. The primary focus of this research lies in the factors influencing sustainable fashion consumption, aiming to provide multidimensional perspectives for researchers, businesses, and governments. After analyzing the 112 research papers, several frequently mentioned factors impacting sustainable fashion consumption include product quality, environmental concern, environmental awareness, and brand image. Moreover, these factors positively correlate with purchasing sustainable fashion products. This study contributes to the theory, practice and adds value to potential future research directions.

A comparative study of mono-exponential and advanced diffusion-weighted imaging in differentiating stage IA endometrial carcinoma from benign endometrial lesions

PurposeThe purpose of the current investigation is to compare the efficacy of different diffusion models and diffusion kurtosis imaging (DKI) in differentiating stage IA endometrial carcinoma (IAEC) from benign endometrial lesions (BELs).MethodsPatients with IAEC, endometrial hyperplasia (EH), or a thickened endometrium confirmed between May 2016 and August 2022 were retrospectively enrolled. All of the patients underwent a preoperative pelvic magnetic resonance imaging (MRI) examination. The apparent diffusion coefficient (ADC) from the mono-exponential model, pure diffusion coefficient (D), pseudo-diffusion coefficient (D*), perfusion fraction (f) from the bi-exponential model, distributed diffusion coefficient (DDC), water molecular diffusion heterogeneity index from the stretched-exponential model, diffusion coefficient (Dk) and diffusion kurtosis (K) from the DKI model were calculated. Receiver operating characteristic (ROC) analysis was used to evaluate the diagnostic efficiency.ResultsA total of 90 patients with IAEC and 91 patients with BELs were enrolled. The values of ADC, D, DDC and Dk were significantly lower and D* and K were significantly higher in cases of IAEC (p < 0.05). Multivariate analysis showed that K was the only predictor. The area under the ROC curve of K was 0.864, significantly higher compared with the ADC (0.601), D (0.811), D* (0.638), DDC (0.743) and Dk (0.675). The sensitivity, specificity and accuracy of K were 78.89%, 85.71% and 80.66%, respectively.ConclusionAdvanced diffusion-weighted imaging models have good performance for differentiating IAEC from EH and endometrial thickening. Among all of the diffusion parameters, K showed the best performance and was the only independent predictor. Diffusion kurtosis imaging was defined as the most valuable model in the current context.

Commodified State Feminism: The Entanglements of Feminist Commodity Activism and Feminist Politics in a Nordic Welfare State

Abstract This article analyzes the entanglements of feminist commodity activism and state feminism. Feminist commodity activism refers to consumption and commodified communication as modes of feminist political participation. Earlier research on these topics has focused on the business sector and on media and popular culture, largely sidelining the state as a site of feminism. This article addresses the increasingly close relations between consumerism and state politics and asks how feminist commodity activism interacts with state feminism. It draws on two empirical cases in the Nordic welfare state of Finland. The first is Uhana Design, a small-scale fashion business, and its Girl Gang campaign that leans on state feminism. The second is Finland's former leading female politicians’ engagements with feminist fashion. By analyzing these cases via three theoretical lenses, business, popular, and state feminism, this article develops the notion of commodified state feminism, paying attention to economic, cultural, and political dimensions of feminist commodity activism and state feminism. It also argues that commodified state feminism is emblematic of the current political context, in which the boundaries between market and politics have become blurred.

Associations Between Psychopathological Symptom Severity Amid the Pandemic and the Childhood Sociodemographic Environment.

It is well-documented that childhood socioeconomic status (SES) is associated with various health conditions in adulthood. Here, we examine the extent to which childhood SES is associated with COVID-19 pandemic anxiety and depression. Participants (n = 212), recruited from Amazon Mechanical Turk, were assessed for depression and anxiety in February 2022 for both the current context and retrospective self-perceived early pandemic depression and anxiety (April 2020). Participants also reported childhood SES and current demographics. Consistent with predated findings, we show a strong, positive correlation between depression and anxiety under both conditions. Paternal unemployment in childhood was associated with increased anxiety, while maternal occupation was not. High household education in childhood was generally associated with greater anxiety and depression, similar to past studies examining education levels and depression. However, the shift from high school to post-secondary degrees (trade school and associate's) was associated with decreased anxiety and depression, which may reflect "essential work" careers, therefore indicating a dualism. Growing up in crowded, de-individualized spaces was associated with lower anxiety and depression, suggesting better conditioning for the imposition of COVID-19 quarantines. Pandemic-related unemployment was associated with an increase in anxiety and depression. Strong political views, regardless of ideology, were associated with increased anxiety. Finally, participants in our cohort perceived their mental health to be worse in the early pandemic for anxiety and depression, up 6.6% and 7.9%, respectively. Our work suggests a complex relationship between SES, demographics, and anxiety and depression during the pandemic. These findings emphasize the importance of exploring the dynamics between early SES and mental health in adulthood, particularly during extended societal stressors.

Post-COVID breathlessness: a mathematical model of respiratory processing in the brain.

Breathlessness is among the most common post-COVID symptoms. In a considerable number of patients, severe breathlessness cannot be explained by peripheral organ impairment. Recent concepts have described how such persistent breathlessness could arise from dysfunctional processing of respiratory information in the brain. In this paper, we present a first quantitative and testable mathematical model of how processing of respiratory-related signals could lead to breathlessness perception. The model is based on recent theories that the brain holds an adaptive and dynamic internal representation of a respiratory state that is based on previous experiences and comprises gas exchange between environment, lung and tissue cells. Perceived breathlessness reflects the brain's estimate of this respiratory state signaling a potentially hazardous disequilibrium in gas exchange. The internal respiratory state evolves from the respiratory state of the last breath, is updated by a sensory measurement of CO2 concentration, and is dependent on the current activity context. To evaluate our model and thus test the assumed mechanism, we used data from an ongoing rebreathing experiment investigating breathlessness in patients with post-COVID without peripheral organ dysfunction (N = 5) and healthy control participants without complaints after COVID-19 (N = 5). Although the observed breathlessness patterns varied extensively between individual participants in the rebreathing experiment, our model shows good performance in replicating these individual, heterogeneous time courses. The model assumes the same underlying processes in the central nervous system in all individuals, i.e., also between patients and healthy control participants, and we hypothesize that differences in breathlessness are explained by different weighting and thus influence of these processes on the final percept. Our model could thus be applied in future studies to provide insight into where in the processing cascade of respiratory signals a deficit is located that leads to (post-COVID) breathlessness. A potential clinical application could be, e.g., the monitoring of effects of pulmonary rehabilitation on respiratory processing in the brain to improve the therapeutic strategies.

Examining tourists' risk-related hesitation and confidence effects on developing distress and associated behavioral responses during COVID-19

PurposeUtilizing the theoretical foundation of the stimulus-organism-response framework, the present work developed and investigated a conceptual model. The work explores the effects of perceived risk of COVID-19 on tourists' choice hesitation and choice confidence. Furthermore, it examines the impacts of choice hesitation and choice confidence on psychological distress, which, in turn, influences purchase intentions and risk-protective behavior. Additionally, the study assesses the boundary effects of vulnerability on the association between choice hesitation, choice confidence, and psychological distress.Design/methodology/approachAn online survey was administered in China during COVID-19 to assess the postulated hypotheses. We collected 491 responses using purposive sampling, and covariance-based structural equation modeling (CB-SEM) was performed to investigate the relationships.FindingsResults show that the perceived risk of COVID-19 positively influences the choice hesitation and negatively impact choice confidence. It was also found that choice hesitation and choice confidence positively developed psychological distress, which, in turn, negatively triggered purchase intentions and positively developed risk-protective behavior. Additionally, perceived vulnerability had a significant moderating impact on the proposed relationships, strengthening psychological distress.Originality/valueIn the current context, this study measures bipolar behavioral outcomes using the S-O-R model. Because cognitive processes influence participation in health preventative behavior during the spread of diseases, we highlighted how the perception of risk and vulnerability to a pandemic serves as a reliable indicator of certain behaviors. This study advances understanding of how the psychological mindset of tourists copes with such circumstances. Due to the pandemic, tourists face limitations in their choices and are placing greater emphasis on adopting protective measures to mitigate associated risks.
