Health Risks Associated with Adopting New-Generation Disposable Products Among Young Adults Who Use E-Cigarettes.

New-generation disposable e-cigarettes have become increasingly popular among young adults in the USA since the FDA's partial flavor ban. This study aims to examine longitudinal changes in health risks among young adults who adopted these novel products, as well as the health effects of device types beyond the effects of other important e-cigarette characteristics. This study recruited e-cigarette users via voluntary response sampling from three college campuses in the USA to respond to four-wave online surveys conducted in four consecutive semesters. Among the participants who adopted disposables during the study, their health risks (dependence symptoms, respiratory symptoms, combustible tobacco use) and e-cigarette consumption characteristics (use frequency, nicotine concentration and flavors) before and after the adoption were compared using paired-sample t- or McNemar's tests. Generalized linear mixed models with a random intercept were conducted on data from the entire sample to investigate the effects of device type (tank, cartridge/pod, disposable) on health risks, controlling for other e-cigarette consumption characteristics. The study sample of 650 e-cigarette users were, on average, 20 years old, with 49% being male, 70% being White, and 13% being Hispanic. Adopting disposables may increase secondary dependence motives (t = 2.42, p < 0.05) and the use of higher levels of nicotine concentration (t = 2.09, p < 0.05) and sweet flavors (x2 = 22.53, p < 0.05) but decrease the number of times of vaping per day (t = -2.18, p < 0.05) and the use of menthol flavors (x2 = 4.57, p < 0.05). Tank use is associated with a higher level of primary dependence motives (b = 0.1998, p < 0.05) and a greater odds of using combustible tobacco (b = 0.4772, p < 0.05). Although disposable use is not associated with the likelihood of using combustible tobacco, it is associated with higher levels of both primary (b = 0.2158, p < 0.05) and secondary (b = 0.2533, p < 0.05) dependence motives. It is not the device type, but rather the frequency of vaping, that affects respiratory symptoms (b = 0.0602, p < 0.05). The findings indicate that when young adults switch to disposables, their e-cigarette dependence and use of sweet-flavored e-liquids increase. Even after controlling for use frequency, nicotine concentration and flavors, using disposables is related to not only instrumental motives that are influenced by psychological and environmental contexts but also heavy, automatic use that can operate without environmental cues. Given the health risks associated with disposable e-cigarettes, more comprehensive tobacco product regulations that consider the impact of device types may be needed.

Repeated presentation of visual threats drives innate fear habituation and is modulated by environmental and physiological factors.

To survive predation, animals must be able to detect and appropriately respond to predator threats in their environment. Such defensive behaviors are thought to utilize hard-wired neural circuits for threat detection, sensorimotor integration, and execution of ethologically relevant behaviors. Despite being hard-wired, defensive behaviors (i.e. fear responses) are not fixed, but rather show remarkable flexibility, suggesting that extrinsic factors such as threat history, environmental contexts, and physiological state may alter innate defensive behavioral responses. The goal of the present study was to examine how extrinsic and intrinsic factors influence innate defensive behaviors in response to visual threats. In the absence of a protective shelter, our results indicate that mice showed robust freezing behavior following both looming (proximal) and sweeping (distal) threats, with increased behavioral vigor in response to looming stimuli, which represent a higher threat imminence. Repeated presentation of looming or sweeping stimuli at short inter-trial intervals resulted in robust habituation of freezing, which was accelerated at longer inter-trial intervals, regardless of contextual cues. Finally, physiological factors such as acute stress further disrupted innate freezing habituation, resulting in a delayed habituation phenotype, consistent with a heightened fear state. Together, our results indicate that extrinsic factors such as threat history, environmental familiarity, and physiological stressors have robust and diverse effects on defensive behaviors, highlighting the behavioral flexibility in how mice respond to predator threats.

Understanding public acceptability of climate policies in Europe

ABSTRACT Urgent and decisive government action to mitigate greenhouse gas emissions is more likely when the proposed measures are popular among the public. This paper compares the drivers of European public support for three alternative policies to combat climate change: carbon taxation, renewable energy subsidies, and minimum energy efficiency standards that apply to household appliances. We combine survey data with regional socio-economic and environmental indicators to provide a comprehensive, comparative analysis of policy acceptance that accounts for the geographic context in which these policies would be implemented. By comparing the drivers among three climate policies, we identify a rural-urban gap in predicting public perception of carbon taxation, which does not exist in the other policies. We also found a positive relationship between regional exposure to fine particular matter (PM2.5) and public support for climate policy, providing novel insights into the influence of environmental factors on public perceptions. This research highlights the importance of environmental and socio-economic context in predicting climate policy acceptance and offers valuable implications for policymakers seeking to garner public support for effective climate change mitigation strategies.

Determinants of self-management behavior in gout: a scoping review.

This study aimed to identify modifiable determinants of self-management behavior in gout. Four databases (MEDLINE, Embase, PsycINFO and CINAHL) were searched using terms related to gout, self-management and determinants of behavior as described in the Theoretical Domains Framework (TDF). Two reviewers independently selected relevant studies via screening of title/abstract and full text. Thematic synthesis was performed for qualitative data; quantitative data was summarized using cross-tabulation displaying the investigated associations of determinants with self-management behavior. The TDF facilitated identification and grouping of determinants. From 2087 unique articles found, 56 studies were included in this review, of which 27 qualitative and 29 quantitative studies. Eight themes were identified: knowledge and skills for self-management, acceptance of disease, beliefs about necessity of self-management to improve gout-related health, resistance and reluctance for medication adherence and dietary alteration/changes, negative emotions influencing self-management, social support and interactions, environmental context, and self-regulation of behavior. Quantitative determinants associated with self-management behavior, predominantly medication adherence, were mapped to 12 of the 14 domains of the TDF. No determinants regarding skills and goals have been identified in quantitative research. Intervention targets for self-management behavior in gout mainly included determinants related to knowledge, implicit and explicit beliefs and attitudes, the environmental context and resources, (social) support and reinforcement.

Récits de vie d’adolescentes en conflit avec la loi à Dakar (Sénégal) : entre défis et ajustements méthodologiques, quelle réflexivité ?

This article addresses the methodological aspects of my doctoral research on the life course of adolescent girls in conflict with the law and their « delinquent » and judicial experience in the face of social control in the Senegalese context. The inherent challenges and adjustments of any ethnographically inspired qualitative research are examined in relation to the context of the study environment and the adopted posture. In accordance with the requirements of an ethnographic orientation, reflexivity during the immersion and distancing phases of the fieldwork made it possible to ensure a methodological critical feedback on these challenges and adjustments. Moreover, the analyses show that they are strongly linked to ethical considerations. To this end, recommendations are made in particular to research ethics boards.

Distinguishing Surface and Bulk Reactivity: Concentration-Dependent Kinetics of Iodide Oxidation by Ozone in Microdroplets.

Iodine oxidation reactions play an important role in environmental, biological, and industrial contexts. The multiphase reaction between aqueous iodide and ozone is of particular interest due to its prevalence in the marine atmosphere and unique reactivity at the air-water interface. Here, we explore the concentration dependence of the I- + O3 reaction in levitated microdroplets under both acidic and basic conditions. To interpret the experimental kinetics, molecular simulations are used to benchmark a kinetic model, which enables insight into the reactivity of the interface, the nanometer-scale subsurface region, and the bulk interior of the droplet. For all experiments, a kinetic description of gas- and liquid-phase diffusion is critical to interpreting the results. We find that the surface dominates the iodide oxidation kinetics under concentrated and acidic conditions, with the reactive uptake coefficient approaching an upper limit of 10-2 at pH 3. In contrast, reactions in the subsurface dominate under more dilute and alkaline conditions, with inhibition of the surface reaction at pH 12 and an uptake coefficient that is 10× smaller. The origin of a changing surface mechanism with pH is explored and compared to previous ozone-dependent measurements.

Unifying Coral Reef States Through Space and Time Reveals a Changing Ecosystem

ABSTRACTAimEcological state shifts that alter the structure and function of entire ecosystems are a concerning consequence of human impact. Yet, when, where and why discrete ecological states emerge remains difficult to predict and monitor, especially in high‐diversity systems. We sought to quantify state shifts and their drivers through space and time in the most ecologically complex marine ecosystem: tropical coral reefs.LocationWorldwide.Time Period1987–2019.Major Taxa StudiedCoral reef communities.MethodsUsing a global dataset of 3375 coral reef surveys, along with 13 time series datasets ranging between 1987 and 2019, we applied a novel double‐dichotomy approach to classify coral reefs into four simplified and discrete states based on the relative contributions of corals versus algae to benthic cover and small‐bodied versus large‐bodied fishes to fish standing stock. We then examined state shifts considering a range of spatial predictors and tested whether states have shifted directionally over time, and the nature of the most common transitions.ResultsWe show that geographic, environmental and anthropogenic context fundamentally shapes coral reef states at the local scale, which explains disparities among case studies, and stakes out critical baseline expectations for regional management efforts. We also reveal clear multi‐decadal state shifts on coral reefs: over time, systems dominated by reef‐building corals and small‐bodied, planktivorous fishes tend to have been replaced with reefs characterised by algae and larger‐bodied fishes.Main ConclusionsOur results suggest a previously unrecognised transition from systems that harness external subsidies through small‐bodied consumers associated with structurally complex live corals, to herbivore‐dominated systems with stronger bottom‐up dynamics. Overall, the partitioning of complex reef ecosystems into a small suite of discrete ecological states suggests that spatial context‐dependency, shifting baselines and changes in reef functioning are crucial considerations for coral reef management in the 21st century.

Computational Multiscale Study of the Interaction Between the PDMS Polymer and Sunscreen-Related Pollutant Molecules

Sunscreen molecules play a critical role in protecting skin from ultraviolet radiation, yet their efficient detection and separation pose challenges in environmental and analytical contexts. In this work, we employ a multilevel modeling approach to investigate the molecular interactions between representative sunscreen molecules and the polydimethylsiloxane (PDMS) polymer, a material widely recognized for its sorbent properties. Our goal is to explore how these interactions can be fine-tuned to facilitate the effective separation of sunscreen molecules in portable membrane inlet mass spectrometry (MIMS) systems, potentially leading to the development of new membrane materials. Using a combination of advanced computational techniques—force field molecular dynamics simulations, semiempirical GFN2-xTB, and density functional theory calculations—we assess the interaction strength and noncovalent interactions of sunscreen molecules, namely oxybenzone, naphthalene, benzo[a]anthracene, avobenzone, and 1,3,5-trichlorobenzene, with PDMS. Additionally, the effect of temperature on the interaction dynamics is evaluated, with the aim of extending the sorbent capacities of PDMS beyond light polar molecules to larger, polar sunscreen compounds. This study provides critical insights into the molecular-level interactions that may guide the design of novel membrane materials for efficient molecular separation.

The heat shock response of plants: new insights into modes of perception and signaling and how hormones contribute.

Plants have evolved specific temperature preferences, and shifts above this range cause heat stress with detrimental effects such as physiological disruptions, metabolic imbalances, and growth arrest. To reduce damage, plants utilize the heat shock response (HSR), signaling cascades that activate the heat shock factors (HSFs), transcription factors that control the heat stress-responsive transcriptome for activation of protective measures. While the core HSR is well-studied, we still know relatively little about heat stress perception and signal integration or cross-talk with other pathways. In the last few years, however, significant progress has been made in this area, which is summarized here. It has emerged that the plant hormones brassinosteroids (BRs) and abscisic acid (ABA) contribute to heat stress tolerance by impacting HSF modes of activity. Also, we began to understand that heat stress is sensed in different cellular compartments and that events in the nucleus, such as nuclear condensate formation via liquid-liquid phase separation, play a key role. In the future, it will be important to explore how these multilayered perception and signaling modes are utilized to understand how environmental context and developmental stage determine the outcome of heat stress effects on plant growth and development.

Barriers and facilitators of adherence to clinical practice guidelines in Germany-A systematic review.

Clinical Practice Guidelines (CPGs) represent evidence-based tools designed to assist healthcare practitioners and patients in decisions in clinical practice. Evidence supports the clinical benefits of adhering to CPGs. However, their successful implementation and adherence in clinical settings often encounter challenges. This systematic review aimed to explore barriers and facilitators influencing adherence to CPGs in Germany. The protocol of this study was registered in the Open Science Framework (OSF) registry (DOI: 10.17605/OSF. IO/GMFUB). In November 2022 we searched on PubMed and Embase for primary studies employing qualitative, quantitative and mixed-methods approaches that focus on barriers or facilitators to CPGs adherence in the Germany. Two reviewers independently screened articles, extracted data, and evaluated the quality of the studies. The collected data on barriers and facilitators of CPG adherence were systematically categorized and analyzed using the Theoretical Domains Framework (TDF). A total of 24 studies were included, mainly focusing on adherence to national CPGs. This review introduces a new domain, guideline characteristics, reflecting the need to address barriers and facilitators to CPG development, implementation, dissemination and format, which couldn't be encompassed within the existing 14 domains of TDF framework. Among healthcare professionals, the most frequently reported influencing factors were related to the environmental context and resources (encompassing aspects such as employer support for CPG utilization), the CPG development and dissemination process (including layout, wording, and interactive tools) and beliefs about consequences (such as contradictions with practical experience). Knowledge (knowledge about the content of CPGs, awareness about published CPGs), primarily as a barrier, and reinforcement facilitators (notably financial support), were also frequently reported. The findings revealed multilevel factors contributing to CPG adherence, with environmental context and resources emerging as the most frequently reported considerations. This systematic review offer holistic insights into the barriers and facilitators of CPG adherence in Germany. The results contribute to a better understanding of the topic and serve as a resource for developing targeted strategies to enhance CPG adherence and implementation within the German healthcare system.

On safety of swelled commercial lithium-ion batteries: A study on aging, swelling, and abuse tests

Lithium-ion battery technology has advanced significantly, making these power sources essential for portable electronic devices such as smartphones. In 2023, global smartphone shipments reached nearly 1.2 billion units, underscoring the widespread reliance on these batteries. However, as batteries age, they may swell and potentially pose explosion risks. To investigate the safety of swollen batteries, this study conducts accelerated aging and swelling tests on lithium-ion batteries from five leading brands, which together represent over half of the global smartphone market share. The research involves a series of comprehensive tests, including Accelerated Rate Calorimeters (ARC) test, mechanical, electrical, and thermal abuse tests in accordance with Chinese national standards, as well as gas composition and theoretical flammability analyses on both new and swollen batteries. The findings indicate that swollen batteries generally exhibit safer behavior under floating charging conditions, and both new and swollen batteries pass the abuse tests within the standard framework. This study suggests that the safety of swollen lithium-ion batteries cannot be categorically labeled as dangerous or safe and should be assessed within the context of specific environments.

Design and Art Tools Formation of Visual Context in Modern Anthropogenic Environment

The purpose of the article is to establish the design and artistic means of forming the cultural-artistic context of modern anthropogenic space. The research methodology involved the use of synthesis and analysis methods with the involvement of interdisciplinary connections (architecture, art history, cultural studies, psychology, design), which made it possible to develop the available theoretical and practical experience on the subject of the article; the method of theoretical generalisation was used to formulate conclusions regarding the outlined problem. The scientific novelty of the article lies in the fact that it actualises the issue of the role of the visual and plastic language of design in the formation of the communicative and cultural content of the anthropogenic environment. Conclusions. With the change of socio-cultural, political and economic conditions, people's requirements for their environment also change. Design and artistic techniques make it possible to dynamically adjust the visual context of the space, to modernise it. The visual plastic design language of the modern anthropogenic environment is presented in artistically decorated stationary and moving objects, their parts, which add character and individuality to it, cause certain emotions in people who interact with such a space. The presence of murals, graffiti, street stencils, sticker art, aerosol art, posters, photo wallpapers, knitted graffiti, mosaics, LED art, media facades, sculptures, video mapping contributes to the formation of a new visual context of the environment, 3D images. Unsystematic, chaotic formation of the visual context of the space can disrupt its artistic integrity. It is worth considering the location of the object, its role in the general structure of the environment, architectural, historical or ethnic context.

Principal Component Analysis for Aggregating Environmental Variables Affecting Electricity Distributors' Operations in Brazil

Theoretical Framework: The National Electric Energy Agency (NEEA) applies benchmarking, especially Data Envelopment Analysis (DEA), to establish distribution tariffs and calculate efficient operational costs. The environmental context of the areas where distributors operate impacts their efficiency, indicating the need to integrate environmental factors into benchmarking models to correct methodological biases and consider unmanageable aspects, ensuring a more accurate analysis of distributor efficiency. Objective: The study applied Principal Component Analysis (PCA) to the environmental variables of electricity distributors in Brazil, facilitating the evaluation of companies under similar operational conditions. Method: The research utilized PCA to condense environmental information from the utilities into a reduced set of variables, simplifying the understanding of impacts on the companies' operational costs. Research Implications: The 21 environmental variables were synthesized into four main components: Territoriality, Climate Factor, Wildfires, and Accessibility/Infrastructure, allowing their use in advanced models that consider environmental factors. Originality/Value: The application of PCA to the environmental variables of electricity distributors in Brazil enables a more homogeneous evaluation based on similar environmental conditions. This approach, still underexplored by ANEEL, assists in analyzing the particularities of the distributors.

Fine‐scale variation in the medium and large‐sized mammal assemblage composition in northeastern Amazon: Drivers of β‐diversity and species interactions

AbstractUnderstanding fine‐scale assemblage composition patterns of mammals is important to increase ecological knowledge and support conservation actions. We investigated whether β‐diversity of medium and large‐sized mammals and its components (replacement and richness difference) are related to distance to major rivers, height above the nearest drainage (HAND), and vegetation height; and whether species interactions shape their spatiotemporal distribution. We used camera traps to monitor the mammal assemblage of the Tumucumaque Mountains National Park, Northeastern Amazon. The difference (Δ) in distance to major rivers and geographic distance between sites affected positively the total β‐diversity and both its components. ΔVegetation height affected total β‐diversity and species replacement, while ΔHAND affected richness differences, and to a lower extent, species replacement. We found evidence that spotted pacas (Cuniculus paca) and ocelots (Leopardus pardalis) adjust their spatiotemporal dynamics to escape from predation and to overlap with abundant prey, respectively. However, we did not find evidence that competition affects the spatiotemporal distribution of any other species. Vegetation height, distance to rivers and HAND influenced mammal assemblages probably through shaping the quality and amount of resources. Predation risk seems to be important in shaping the use of time and space by prey, while the distribution of prey is important for the use of time and space for predators. Furthermore, other niche differentiation mechanisms may explain why competition did not affect the species' spatiotemporal dynamics. We highlight the need to include different environmental contexts within protected areas to promote mammal diversity and conservation.

MEXICAN INTEROCEANIC CORRIDOR: TOWARD A LIKELY SOCIALLY INCLUSIVE AND SUSTAINABLE REGION IN SOUTHWESTERN MEXICO

Mexican Interoceanic Corridor or Tehuantepec's Transisthmian Corridor (along with the Mayan Train) represents one the two largest iconic and challenging Mega Projects implemented in Southwestern Mexico, funded by Mexican Government, in the same so-called “Macrosouth region” or just Macrosouth, here on, (integrated by three economic subregions, namely, South-Pacific, Southern and South-western regions). Despite both projects ultimately aim to foster economic growth in such a region, the former aims to stimulate growth through an increased tourism flow from the wealthy Mayan Riviera zone toward the Gulf of Mexico's long-lagged region by railroad through the Mayan Train recently inaugurated by President Lopez Obrador,vid AMLO(Dec 22, 2023).Although the main focus of our attention here, namely, the Interoceanic Corridor, given its geoeconomic and geo strategic relevance for the country since it is expected to skyrocket Mexican exports and commercial activity through this facility and thus fostering economic growth throughout the Corridor stripe and spread it out throughout its neighboring regions such as those above referred in the coming years given its previlegious geographic location under the global context in which Mexico is currently immersed. Accordingly, the article aims to assess and highlight the socio economic relevance of the Mexican Corridor megaproject and its likelihood to achieve by this means simultaneously economic growth and people's well-being in this region as an expected consequence of the intensive commercial thorugh its operation and industrial activity generated by the production of ten industrial parks to be implemented along the Corridor (backed by a host of full-fledged refurbished and renewed productive infrastructure around it) such as railway itself and road transport and port facilities along the end lines of the Corridor stripe (and the entire Macroregion) focused on supporting the expected massive commercial flow of merchandise and concomitant export boom back and forth through the Atlantic and Pacific oceans, shortly. Furthermore, all these significant public investments, unlike prior neoliberal investment priorities in the past, these new investments are nurtured upon a framework of a socially inclusive and sustainable strategy tailored by the Mexican government for the Corridor zone to promote simultaneously economic growth and people’s well-being in the Transismithian stripe in the years to come. However, the challenge for the Mexican state, through its policymakers, is to achieve such an equilibrium between economic growth and population well-being in this region under a sustainable environmental context. Accordingly, in short, the purpose of this article is to explore the likelihood of Mexico attaining the above-referred equilibrium and implementing a socially inclusive strategy within a long-time deprived and lagged region from the rest of the country such as the Transisthmian Corridor stripe and its neighboring regions, such as the South-Pacific and Gulf of Mexico, in the foreseeable future along with its likely perspectives and socioeconomic and environmental implications.

Exploration of barriers to treatment for patients with eating disorders in Chile

BackgroundEating disorders (EDs) are associated with high morbidity and mortality, affecting predominantly young people and women. A delay in starting treatment is associated with chronic and more severe clinical courses; however, evidence on barriers and facilitators of access to care in Latin America is scarce. We aimed to identify barriers and facilitators of ED treatment in Chile from the perspective of patients, relatives, and health professionals.MethodsQualitative approach through semi-structured interviews with patients, their relatives, and health professionals. Participants were recruited from two ED centers in Santiago, Chile (one public and one private). Analysis was mainly based on Grounded Theory, using MAXQDA software.Results40 interviews were conducted (n = 22 patients, 10 relatives, and 8 health professionals). The mean age of patients was 21.8 years, while the mean duration of untreated ED was 91.4 months (median 70 months). Five categories emerged with intersections between them: patient (P), family and social environment (FSE), health professionals (HP), healthcare system (HCS), and social and cultural context (SCC). Relevant barriers appeared within these categories and their intersections, highlighting a lack of professional knowledge or expertise, cultural ignorance or misinformation regarding EDs, and patient’s ego-syntonic behaviors. The main facilitators were patients’ and relatives’ psychoeducation, recognition of symptoms by family members, and parents taking the initiative to seek treatment.ConclusionsThis study provides information regarding access to treatment for patients living with EDs in Chile. A practical public health approach should consider the multi-causality of delay in treatment and promoting early interventions.Plain English SummaryEating disorders (EDs) may severely affect the daily functioning of people enduring them. A delay in starting treatment is associated with a disease that is more difficult to treat. To our knowledge, there are no published studies carried out in Latin America exploring factors influencing treatment initiation in EDs patients. This study aimed to identify facilitators of and barriers to treating patients with EDs in Chile. We interviewed patients (n = 22), their relatives (n = 10), and health professionals (n = 8) from a private and a public center in Santiago, Chile. Our analysis showed that the main barriers to starting treatment were the lack of professional knowledge in ED, the monetary cost of illness, and cultural misinformation. Facilitators were related to the role of the family in recognizing and addressing the disease while being educated in EDs by professionals. This study helps to provide data about treatment access in developing countries. While facilitators and barriers were similar to others reported in the literature, the untreated ED’s duration was longer. It is essential to address these barriers to provide access to treatment more efficiently and prevent severe and enduring forms of disease.

Anthropometric indices growth references (length, Weight and Head Circumferences) of children aged 0–24 months in North-East of Iran by GAMLSS

BackgroundGrowth references play a crucial role in the screening, evaluation, and surveillance of children, aiding in the early identification of the requirement for diverse growth-promoting interventions. Variations in human growth across distinct ethnic cohorts arise from genetic disparities, lifestyle variances, nutritional diversity, and diverse social and environmental contexts. Consequently, the selection of growth references markedly influences the prevalence of developmental disorders and nutritional imbalances in children. The study aims to assess the growth percentile of children in the north-east of Iran and establish population-specific reference charts for length, weight, and head circumference spanning from birth to 24 months.MethodsThis cross-sectional population-based research conducted in the north-east of Iran, from 2016 to 2023. The Data extracted from the electronic health records of Mashhad University of Medical Sciences. All apparently healthy children aged from birth to 24 months who were measured at least once by health staff at the ages of birth,1,2,4,6,7,9,12,15,18,24 months were included. The target population of the study were 479,089 children (96.21%), encompassing 233,565 girls (48.75%) and 245,524 boys (51.25%). Gender-specific percentile curves for length, weight, and head circumference concerning age, as well as weight concerning length, were derived using the GAMLSS approach.ResultsFrom the anthropometric information of 479,089 children (245,524 boys and 233,565 girls), growth charts were constructed. In comparison to the standard WHO chart, Iranian neonates displayed lower weight across all percentiles during the first month after birth, exhibited decreased head circumference at the 3rd percentile, and boys showed reduced length across all percentiles. After this age, Iranian children demonstrated increased weight, length, and head circumference.ConclusionsThis research introduces the inaugural large-scale endeavor for indigenous reference charts. Through the noted distinctions from the international reference, the utilization of this novel resource offers the potential to enhance the surveillance of children’s growth within the area. Moreover, by accurately assessing growth anomalies such as underweight, stunting, and wasting, it expands the domain of impactful policies in this sphere. Simultaneously, it enables the exploration of the secular trend of children’s growth in the forthcoming years.

Co-creation as open innovation and its impact on environmental performance: Comparative insights from university and vocational students

This study addresses the urgent need for innovative solutions to environmental issues by focusing on youth development within educational institutions, which play a crucial role in fostering environmentally conscious behaviors. Despite increasing awareness, there is a gap in understanding how educational settings can effectively promote sustainability through collaborative approaches, such as co-creation as an open innovation model and user engagement strategies. This research investigates the mediating role of co-creation between environmental knowledge and environmental performance, comparing university and vocational students. Data were collected from 678 respondents in Thailand and analyzed using structural equation modeling and multigroup analysis. The findings reveal that environmental knowledge positively influences environmental performance and co-creation activities for both groups, with a more significant mediating effect of co-creation among vocational students. This suggests that vocational students respond more effectively to practical, collaborative approaches to digital innovation in the environmental context. The study also highlights the relevance of the Information Deficit Model, which posits that individuals often do not engage in sustainable behaviors due to insufficient knowledge or information. These results demonstrate the critical role of educational institutions in enhancing sustainability practices by leveraging co-creation and environmental knowledge. The insights from this study are valuable for educators and policymakers seeking to develop user engagement strategies tailored to different student groups, ultimately improving environmental performance and fostering innovation in sustainability practices.

Factors affecting coaching in higher education: a meta-synthesis approach

PurposeThe purpose of this study was to identify and investigate which factors affect coaching in higher education.Design/methodology/approachThe study employed a qualitative meta-synthesis method. Based on the seven-step method (Sandelowski and Barroso, 2006), articles related to coaching in higher education were searched in five databases between 2012 and 2022. After step-by-step reviews and implementation of the critical evaluation skills program, 34 articles were selected from 1,711 sources.FindingsFollowing the analysis of 58 obtained codes, seven sub-themes and three themes were extracted. The results showed that the key factors affecting coaching in higher education include individual (personal skills, personal attitudes, personal behaviors), structural (environmental contexts, organizational contexts), and managerial factors (planning actions, supporting actions).Practical implicationsThe present study provides a framework for policy-making, implementation, evaluation and development of coaching programs in universities and provides a great help and support for planners and administrators of higher education institutions who want to design and implement coaching for the first time.Originality/valueThe presented factors provide effective information to higher education institutions so that they can offer coaching intervention more efficiently and help them allocate resources in a more efficient and strategic manner.

MSDA-HLGCformer-based context-aware fusion network for underwater organism detection

Underwater organism detection is crucial for marine ecology research and resource management. However, underwater images often suffer from issues like blurring, noise, and color distortion, making it challenging to distinguish targets from complex backgrounds. Existing detection methods struggle to separate targets in such conditions. To address these problems, we propose a Cross-Context Fusion Transformer YOLO network (CCFT-YOLO) for underwater organism detection. Specifically, we propose an MSDA-HLGCformer backbone network that captures and integrates local features at different depths and distances through the Multi-Scale Dilated Attention (MSDA) block at the low level, while at the high level, a hierarchical local–global context former (HLGCformer) is developed to contextualize the information at each scale, allowing the model to focus on the global context of the underwater environment. A context-aware cross-level fusion module (CACLFM) is designed to balance the retention of salient target and background texture information by integrating local and global information. Quantitative and qualitative experimental results show that CCFT-YOLO is competitive and robust in underwater organism detection compared to other state-of-the-art detectors.
