Authors: Cadet Fabienne , Gironda John T. , O'Leary Bay , Petrescu Maria 
Published: September 2024

AbstractThis paper develops the metaverse quality (MV‐Qual) scale and explores the various factors that may impact consumers' perceptions of quality and value when purchasing virtual products in a metaverse world. Utilizing Flow Theory and SERVQUAL as theoretical lenses to conduct our research, a framework was developed and tested, demonstrating how various factors are interconnected and impact consumers' shopping experiences in the metaverse. Data were collected from a national sample of 322 metaverse users in the United States and analyzed using partial least squares structural equation modeling in SmartPLS, complemented by a neural network causal analysis in Neusrel. The results demonstrated that several factors impact metaverse store quality and perceived virtual product value, including control, vividness, avatar design, rarity, and resale value. Subsequently, metaverse store quality and perceived virtual product value positively impact the intention to purchase virtual products in metaverse. This research contributes to the advancement of understanding consumer behavior in the metaverse and adds to the emerging marketing literature on the metaverse. Furthermore, the MV‐QUAL scale developed serves as a practical tool that both marketing researchers and practitioners can use to enhance understanding and discover new ways to improve the metaverse consumer experience.
The anti‐consumption journey: Unplugging for improved well‐being
Authors: Anderson Kelley Cours , Wallach Karen Anne , Grimes Magdiel 
Published: September 2024

AbstractConsumers are exploring ways to obtain control and limit their existing consumption levels in response to growing concerns about well‐being. This article introduces the anti‐consumption journey, which extends prior work on journey mapping, by evaluating the distinct journey when the goal is not to consume. Within the context of the “digital detox,” we use a hermeneutic approach to analyze qualitative data from blog posts by digital detox consumers, survey data from a digital detox retreat, and interviews with digital detox service providers. We highlight an emergent model of the facilitators and inhibitors consumers encounter throughout the anti‐consumption journey. This novel roadmap offers insights to further understand tensions between a consumer's subjective state of agency and culturally embedded assumptions of technology consumption. Theoretical and practitioner implications are discussed.

AbstractBackgroundData on shock severity and bleeding events in patients with temporary mechanical circulatory support (tMCS) are limited. We investigated the relationship between the Society for Cardiovascular Angiography and Interventions (SCAI) shock stage classification and bleeding events in patients with tMCS.MethodsWe evaluated the data of 285 consecutive patients with tMCS who were admitted to our institution between June 2019 and May 2022. At the time of tMCS initiation, 81 patients (28.4%) were in SCAI stage A, 38 (13.3%) in stage B, 69 (24.2%) in stage C, 33 (11.6%) in stage D, and 64 (22.5%) in stage E. Multivariable logistic regression modeling was used to assess the association between the SCAI shock stage and in‐hospital bleeding events.ResultsIn‐hospital bleeding occurred in 100 patients (35.1%). The bleeding event rate increased incrementally across the SCAI shock stages (stage A, 11.1%; stage B, 15.8%; stage C, 37.7%; stage D, 54.6%; stage E, 64.1%). In‐hospital bleeding was associated with the SCAI shock stage (p < 0.001). Compared with stage A, the adjusted odds ratios for in‐hospital bleeding were 1.48 (95% confidence interval [CI] 0.47–4.66), 6.47 (95% CI 2.61–10.66), 11.59 (95% CI 3.77–35.64), and 7.85 (95% CI 2.51–24.55) for stages B, C, D, and E, respectively.ConclusionsThe SCAI shock stage predicted subsequent bleeding events in patients with tMCS. This simple scheme may be useful for tailored risk‐based clinical assessment and management of patients with tMCS.
Autofluorescence for the Visualization of Microorganisms in Biodeteriorated Materials in the Context of Cultural Heritage
Authors: Stratigaki Maria 
Published: September 2024

AbstractMicroorganisms, including fungi, bacteria, cyanobacteria, and algae, frequently colonize the surfaces of cultural heritage materials. These biological agents can cause biodeterioration through various mechanisms, resulting in aesthetic alteration, physical disruption, or compromise of mechanical integrity. To assess the presence and diversity of microorganisms, a combination of microscopy techniques is commonly used in conjunction with results from both culture‐dependent and culture‐independent methods. However, microbial populations are often underestimated. To address this issue, microorganisms can be detected by their intrinsic fluorescence, which can be observed via fluorescence microscopy. This approach facilitates the mapping of the spatial arrangement of microorganisms and the understanding of colonization patterns, thereby complementing established imaging techniques and providing insight into the interactions of microbial communities with the substrate. Given the limited research in this area, we examine the potential of microorganism autofluorescence as a molecular tool for investigating biodeterioration in artistic and architectural heritage, with a particular focus on paper and stone materials. Identifying and understanding the diverse microbiota that may be present is crucial for developing tailored and effective preventive measures and conservation treatments, as some of the species discovered may pose significant risks to both artifacts and human health.
Development of a Facile and Green Synthesis Strategy for Brightly Fluorescent Carbon Dots from Various Waste Materials
Authors: Fernandes Sónia , Algarra Manuel , Gil Antonio , Esteves da Silva Joaquim , Pinto da Silva Luís 
Published: September 2024

AbstractCarbon dots (CDs) are fluorescent carbon‐based nanomaterials with remarkable properties, making them more attractive than traditional fluorophores. Consequently, researchers focused on their development and application in fields such as sensing and bioimaging. One potential advantage of employing CDs is using organic waste as carbon precursors in their synthesis, providing a pathway for waste upcycling for a circular economy. However, waste‐based CDs often have low fluorescence quantum yields (QYFL), limiting their practical applications. So, there is a need for a well‐defined strategy to consistently produce waste‐based CDs with appreciable QYFL, irrespective of the starting waste material. Herein, we developed a fabrication strategy based on the hydrothermal treatment of waste materials, using citric acid as a co‐carbon precursor and ethylenediamine as N‐dopant. This strategy was tested with various materials, including corn stover, spent coffee grounds, cork powder, and sawdust. The results showed consistently appreciable QYFL, reaching up to ~40 %. A Life Cycle Assessment (LCA) study demonstrated that producing these waste‐based CDs has lower environmental impacts compared to CDs made solely from commercial reagents. Thus, we have established a framework for the environmentally friendly production of CDs by upcycling different waste materials without significant sacrifices in performance (QYFL).

Authors: Anitha Raja , Murugan Mahalingam 
Published: September 2024

SummaryThe proliferation of network devices capable of gathering, transmitting, and receiving data over the Internet has spurred the widespread adoption of Internet of Things (IoT) devices, particularly in resource‐oriented applications. Integrating blockchain, IoT, homomorphic encryption, and federated learning requires a balance between computational requirements and real‐time performance. Secure key management is crucial to maintain data privacy and integrity. Compliance with privacy regulations requires careful implementation of privacy‐preserving mechanisms in blockchain‐enabled IoT environments, which can be subjected to various attacks. Addressing these challenges requires interdisciplinary expertise, research, and innovation to develop more efficient and effective privacy‐preserving techniques tailored to the unique characteristics of such environments. This research introduces the Modified Homomorphic Encryption Federated‐based Adaptive Hybrid Dandelion Search (MHEF‐AHDS) algorithm as an effective framework to enhance security in blockchain‐enabled IoT systems. The amalgamation of Modified Homomorphic Encryption (MHE) and Federated Learning (FL) constitutes a potent alliance that addresses privacy concerns within collaborative and decentralized machine learning environments. This facilitates secure and adaptable data collaboration, effectively mitigating privacy risks associated with sensitive information. The integration of quantum machine learning into security applications presents an exciting opportunity for distinctive progress and innovation. Within this work, the Adaptive Hybrid Dandelion optimization algorithm, featuring an Initial search strategy, is employed for hyperparameter optimization thereby elevating the performances of the proposed MHEF‐AHDS method. Furthermore, the integration of smart contracts and Blockchain‐based IoT enhances the overall security of the proposed method. MHEF‐AHDS comprehensively tackles privacy, security, and scalability challenges through robust security measures and privacy enhancements. The performance evaluation of the MHEF‐AHDS method encompasses a thorough analysis based on key metrics such as throughput, latency, scalability, energy consumption, accuracy, precision, recall, and f1‐score. Comparative assessments against existing methods are conducted to gauge the effectiveness of the proposed method in addressing security, privacy, and scalability concerns.
Scale‐dependent population drivers inform avian management in a declining saline lake ecosystem

Published: September 2024

AbstractShrinking saline lakes provide irreplaceable habitat for waterbird species globally. Disentangling the effects of wetland habitat loss from other drivers of waterbird population dynamics is critical for protecting these species in the face of unprecedented changes to saline lake ecosystems, ideally through decision‐making frameworks that identify effective management options and their potential outcomes. Here, we develop a framework to assess the effects of hypothesized population drivers and identify potential future outcomes of plausible management scenarios on a saline lake‐reliant waterbird species. We use 36 years of monitoring data to quantify the effects of environmental conditions on the population size of a regionally important breeding colony of American white pelicans (Pelecanus erythrorhynchos) at Great Salt Lake, Utah, US, then forecast colony abundance under various management scenarios. We found that low lake levels, which allow terrestrial predators access to the colony, are probable drivers of recent colony declines. Without local management efforts, we predicted colony abundance could likely decline approximately 37.3% by 2040, although recent colony observations suggest population declines may be more extreme than predicted. Results from our population projection scenarios suggested that proactive approaches to preventing predator colony access and reversing saline lake declines are crucial for the persistence of the Great Salt Lake pelican colony. Increasing wetland habitat and preventing predator access to the colony together provided the most effective protection, increasing abundance 145.4% above projections where no management actions are taken, according to our population projection scenarios. Given the importance of water levels to the persistence of island‐nesting colonial species, proactive approaches to reversing saline lake declines could likely benefit pelicans as well as other avian species reliant on these unique ecosystems.

Published: September 2024

ABSTRACTObjectiveIn cross‐sectional and retrospective research, parental binge eating is associated with their children's eating psychopathology. The current study extended the evidence by cross‐sectionally and longitudinally examining the relation between parental binge eating and binge eating and weight‐control behaviors in the next generation of their adolescent children and young adult children in a population‐based sample.MethodsAdolescents (Time 1: M = 14.5, SD = 2.0 years) (n = 2367), followed into adulthood (Time 2: M = 22.1, SD = 2.0 years), and their parents (n = 3664) were enrolled in EAT 2010–2018 and Project F‐EAT 2010. The current study examined parental binge eating, and child binge eating and weight‐control behaviors. Adjusted models covaried for child gender, age, and race/ethnicity.ResultsApproximately 7% of adolescents at Time 1 had at least one parent who reported binge eating with no differences by child's age, gender, or race/ethnicity. Having at least one parent experiencing binge eating at Time 1 (vs. not) was associated cross‐sectionally with adolescent children's use of extreme weight‐control behaviors (9.6% vs. 4.8%; Risk Difference [RD] = 4.9%) and associated longitudinally with binge eating during young adulthood (21.1% vs. 11.6%; RD = 9.5%). Other associations did not reach statistical significance.ConclusionsChildren of parents with binge eating appear to have elevated risk of extreme weight‐control behaviors during adolescence and binge eating in young adulthood. Clinicians should assess whether eating psychopathology extends to other family members, and offer additional support to parents with binge eating. Further research is needed to identify risk factors in the children of parents with binge eating and to assess strategies for prevention.
Potential drivers and implications of a balanced breeding sex ratio in a small population of an imperiled species with environmental sex determination
Authors: Silver‐Gorges Ian , Shamblin Brian M. , Ashford Mason , Bower Paityn , Fuentes Mariana M. P. B. 
Published: September 2024

AbstractSmall populations of imperiled species are susceptible to the negative consequences of skewed sex‐ratios. In imperiled species with environmental sex determination such as sea turtles, examining sex ratios across a range of environments and population abundance levels can provide insight into factors that influence population resilience, which can then be the foci of management plans for these species. Breeding sex ratios (the ratio of actively breeding males to females during a reproductive season; BSRs) extrapolated from genetic parentage analyses are a common approach for enumerating sex ratios in sea turtles. Such analyses also allow for the characterization of multiple paternity within sea turtle clutches, which should reflect BSRs and breeding behaviors. We characterized the first BSR for a breeding assemblage of loggerhead sea turtles (Caretta caretta) belonging to the temperate, low‐abundance Northern Gulf of Mexico Recovery Unit using genotypes of 16 microsatellite loci from nesting females and hatchlings. Unlike prior studies at both more‐tropical and more‐temperate, and higher‐abundance, Recovery Units in this region, we found a balanced BSR of 1.3:1 males:female and a low incidence (~17%) of multiple paternity. This suggests that there are relatively few males breeding at this assemblage and within this Recovery Unit. Beaches in this region are expected to produce substantial numbers of male hatchlings based on sand temperature data. The relative dearth of mature males may then be due to hydrologic disturbances that disproportionately affect the fitness and survival of male hatchlings, or due to demographic stochasticity. More work is needed to study the factors that might influence male hatchling production and fitness in this region, particularly as climate change is predicted to lead to feminization in global sea turtle populations. Our work demonstrates the broad utility of characterizing BSRs and other sex ratios across a range of populations in imperiled, environmentally sensitive species.
Analysis and evaluation of the usefulness of open data for research projects—The case of the BrineRIS project
Authors: Górniak‐Zimroz Justyna , Worsa‐Kozak Magdalena , Szostak Karolina 
Published: September 2024

AbstractOpen research data refer to publicly available scientific information that can be accessed free of charge, usually provided by public data sources. Users must comply with specific requirements set by the institutions providing the data and always acknowledge the source of the data when processing, transmitting, storing or publishing it. One of the tasks of the BrineRIS project is the mapping of brine resources, requiring reliable data on the location of exploration facilities, environmental characteristics, brine exploitation parameters and formal and legal information. These data come from a review of various archives, databases and survey results. Initially, information on the location of the sources should be obtained, which may be available in publicly accessible databases. Next, geological and hydrogeological parameters, which can be obtained from scientific papers and reports, are useful. An important part of the project is also the analysis of legal regulations concerning water extraction and environmental protection. Therefore, data should be obtained from various sources, such as public administration, state institutions or research units. These will serve to develop the database needed to perform further analyses within the BrineRIS research project. It is therefore crucial to carefully collect, analyse and assess the usefulness of the data.
Improving safety in complex systems: A review of integration of functional resonance analysis method with semi‐quantitative and quantitative approaches
Authors: Kumar Ashish , Upadhyay Rahul , Samanta Biswajit , Bhattacherjee Ashis 
Published: September 2024

AbstractFunctional resonance analysis method (FRAM) is extensively employed in analyzing and managing performance variabilities. Additionally, semi‐quantitative and quantitative methods have been increasingly integrated with the FRAM to analyze complex socio‐technical systems to improve safety levels. This review article presents a comprehensive and updated survey of current literature focused on semi‐quantitative and quantitative methods employed for quantifying performance variabilities and exploring aggregation/propagation rules. A total of 1659 studies published between 2012 and March 2024 from various scientific databases were systematically examined using preferred reporting items for systematic review and meta‐analysis, identifying 29 studies that met inclusion criteria. The identified studies were categorized into four groups based on the quantitative methods employed: Monte Carlo simulation, fuzzy logic, cognitive reliability and error analysis method, and miscellaneous approaches. While different methodologies had unique strengths, they commonly relied on expert judgment for data collection, whether for defining probability distributions in Monte Carlo simulations, membership functions, and fuzzy rule bases in fuzzy inference systems, or selecting common performance conditions, determining their interrelationships, and assigning scores. Addressing bias from expert judgment in assessing performance variabilities can be achieved by using suitable experts' opinions integration techniques, and leading safety indicators in the analysis.

Published: September 2024

AbstractIn the current numerical study, the viability and sustainability of a solar heat collector (SHC) have been rigorously analyzed through the lens of exergy analysis. The SHC with roughness in the form of symmetrical V‐rib gaps has been selected for detailed numerical investigation. The study focuses on deriving the dominant parameters affecting the performance of the SHC, including the relative gap width (), number of gaps () in the limbs of ribs, and fluid flow Reynolds number, which varied from 4000 to 18,000. The absorber plate with roughness was thoroughly examined to evaluate the losses and irreversibility that persist in the thermal system. The results of the numerical analysis revealed the maximum exergy efficiency to be 3.87%. Furthermore, the study examined the long‐term feasibility of the system, evaluating its sustainability index at a remarkable 1.0319 value, while the magnitude of the waste–energy ratio fetched an impressive score of 0.991. Additionally, the study found that the system has a significant improvement potential of 10.04. Overall, these findings provide critical insights into the performance and sustainability of SHCs, paving the way for future research and development in this crucial field.
Numerical and experimental investigations of thermohydraulic performance enhancement of triangular duct solar air heaters using circular wing vortex generators

Published: September 2024

AbstractThis study presents the thermohydraulic performance enhancement in a triangular duct solar air heater (TSAH) using circular wing vortex generators (CWVGs) on the absorber plate using computational fluid dynamics (CFD) methodology for the Reynolds number (Re) range of 6000–21,000. The use of wing vortex generators offers relatively lower interference with the core flow region, while the circular geometry offers a smooth curved edge, which reduces multiple vortex interactions in the wake region, thereby limiting the pressure drop. This study explores the impact of flow attack angle, longitudinal pitch, transverse pitch, and diameter of CWVG on the thermohydraulic performance of TSAH. The results reveal that a lower flow attack angle exhibits enhanced heat transfer with a lower friction factor penalty. The nondimensional diameter greater than d/Dh = 0.325 tends to limit heat transfer and exhibits an increased friction factor. The transverse pitch parameter also exhibits a similar trend where the threshold nondimensional pitch is found to be 1.5. The highest improvement in Nu is 4.37 times that of smooth duct for d/Dh = 0.433, Pl/d = 1, Pt/d = 1.5 and α = 20° at Re = 6000. The highest rise in friction factor is about 10.23 times that of smooth duct for d/Dh = 0.433, Pl/d = 1.0, Pt/d = 1.5, and α = 20° at Re = 21,000. The highest thermohydraulic performance parameter (THPP) value is about 2.23 at Re = 6000, with THPP values ranging from 1.69 to 2.23 across different CWVG configurations. Finally, mathematical correlations are developed for Nu and friction factors which are in close agreement with CFD results, with deviations averaging 5.03% and 3.69%, respectively.
