Functional response metrics explain and predict high but differing ecological impacts of juvenile and adult lionfish.

Recent accumulation of evidence across taxa indicates that the ecological impacts of invasive alien species are predictable from their functional response (FR; e.g. the maximum feeding rate) and functional response ratio (FRR; the FR attack rate divided by handling time). Here, we experimentally derive these metrics to predict the ecological impacts of both juvenile and adult lionfish (Pterois volitans), one of the world's most damaging invaders, across representative and likely future prey types. Potentially prey-population destabilizing Type II FRs were exhibited by both life stages of lionfish towards four prey species: Artemia salina, Gammarus oceanicus, Palaemonetes varians and Nephrops norvegicus. FR magnitudes revealed ontogenetic shifts in lionfish impacts where juvenile lionfish displayed similar if not higher consumption rates than adult lionfish towards prey, apart from N. norvegicus, where adult consumption rate was considerably higher. Additionally, lionfish FRR values were very substantially higher than mean FRR values across known damaging invasive taxa. Thus, both life stages of lionfish are predicted to contribute to differing but high ecological impacts across prey communities, including commercially important species. With lionfish invasion ranges currently expanding across multiple regions globally, efforts to reduce lionfish numbers and population size structure, with provision of prey refugia through habitat complexity, might curtail their impacts. Nevertheless, the present study indicates that management programmes to support early detection and complete eradication of lionfish individuals when discovered in new regions are advised.

Global impact of COVID-19 on food safety and environmental sustainability: Pathways to face the pandemic crisis.

The COVID-19 pandemic poses ongoing challenges to the sustainability of various socioeconomic sectors, including agriculture, the food supply chain, the food business, and environmental sustainability. This study employs data obtained from the World Health Organization (WHO), and Food and Agriculture Organization (FAO), as well as scientific and technical research publications, to evaluate the impacts of COVID-19 on agriculture and food security. This article seeks to highlight the profound influence of the COVID-19 pandemic on agriculture, the supply and demand of food, and the overall safety of food. The article also explores the several pathways by which COVID-19 can be transmitted in these areas and the various technologies employed for its detection. The ongoing and post-pandemic ramifications are substantial since they could decrease agricultural output due to limitations on migration, a downturn in international trade, less buying capacity, and disturbances in food production and processing. Therefore, based on this thorough investigation, recommendations are issued for mitigating and controlling the pandemic's effects.

Impact of floods on the environment: A review of indicators, influencing factors, and evaluation methods.

Floods have a wide range of environmental effects. However, owing to the complex composition of the environment and the numerous factors influencing environmental flood risk, few studies have systematically analyzed the impact of floods on the environment. After reviewing the various impacts of floods on the environment, we summarized them into four indicators (water pollution, erosion and deposition, biomass impact, and biodiversity impact) and analyzed the interrelationships between the four indicators. We then summarized 14 key factors affecting the degree of impact of floods on the environment (flood depth, velocity, duration, sediment concentration, timing of flood, temperature, point source and non-point source, height, age, waterlogging tolerance of plants, migration ability of animals, survival time of animals during floods, species richness, and biomass density) and analyzed their influence mechanisms on each indicator. We then compared the principles, scope of application, accuracy, and limitations of six environmental flood impact evaluation methods and found that the multi-factor evaluation method has great application prospects. Finally, we proposed two recommendations for future research to assess and reduce environmental flood impacts. This review provides a comprehensive understanding of the impact of floods on the environment and a basis for evaluating the impact and formulating measures to mitigate the degree of impact.

Impairment of inhibitory control due to repetitive subconcussions from indirect brain impacts: evidence from event-related potentials and resting-state EEG complexity in parachuters.

The present study aims to investigate the unknown relationship between inhibitory control and repetitive subconcussion induced by the indirect brain impacts. We enrolled 28 parachuters exposed to repetitive subconcussion (SC) and 27 matched health controls (HC). Parachuters who have completed at least 70 actual parachuting (71-112 times) and at least 1,500 simulated platform jumps (1500-4500 times) were included in the SC group. The SC group had a reduced accuracy rate in both the Stroop congruent and incongruent conditions. Larger N2 and N450 amplitudes were elicited in the frontal regions of the SC group, which indicate compensatory adaptations to the deficit in conflict monitoring. The reduced frontal resting-state EEG complexity in full-band (1-40Hz) may demonstrate the frontal structural damage following the indirect brain impacts of repetitive subconcussion. Pearson correlation analysis showed that in the SC group, the frontal beta-band sample entropy values are positively correlated with the accuracy rate of the Stroop incongruent condition, suggesting the frontal beta-band sample entropy values may serve as potential electrophysiological markers of impaired inhibitory control after indirectly repetitive brain impacts. This study provides the robust evidence that repetitive subconcussion resulting from indirect brain impacts may lead to impairment of inhibitory control.

The academic Great Gatsby Curve.

The Great Gatsby Curve measures the relationship between income inequality and intergenerational income persistence. By using genealogical data of over 245 000 mentor-mentee pairs and their academic publications from 22 different disciplines, this study demonstrates that an academic Great Gatsby Curve exists as well, in the form of a positive correlation between academic impact inequality and the persistence of impact across academic generations. We also provide a detailed breakdown of academic persistence, showing that the correlation between the impact of mentors and that of their mentees has increased over time, indicating an overall decrease in academic intergenerational mobility. We analyse such persistence across a variety of dimensions, including mentorship types, gender and institutional prestige.

Asserting the visibility of social work in science.

Scientific evidence has shown that Social Work has frequently been considered a second-level discipline in the traditional sexist hierarchy, because pioneers and most social workers are women. The twofold objective of this article is to analyze the dynamics that overcome this consideration and to put forward actions to go further in the near future. The factors that limit these actions and those that make them possible are studied. This article exposes the dynamics of the current transformation of Social Work, namely, the increase in the importance of social impact in social research, the increase in interdisciplinarity, and the impact of interdisciplinary research.

Exploring social media determinants in fostering pro-environmental behavior: insights from social impact theory and the theory of planned behavior.

Introduction: This study investigates the impact of social media on pro-environmental behavior (PEB) through the lenses of the Theory of Planned Behavior (TPB) and Social Impact Theory. The research aims to elucidate how social media influences Environmental Attitude (EA) and Subjective Norms (SN), and how these factors contribute to Behavioral Intentions (BI) that ultimately affect PEB. Additionally, it examines the moderating effect of Perceived Behavioral Control (PBC) on the relationship between BI and PEB. Methods: To explore these relationships, the study employs a dual methodological approach using Variance-Based Structural Equation Modeling (VBSEM) and Artificial Neural Networks (ANN). Data were collected from two distinct samples: 1200 participants from Taiwan for the SEM analysis and 602 respondents for the ANN study. SEM was utilized to explore causal relationships, while ANN was employed to enhance predictive accuracy. Results: The SEM analysis reveals that social media significantly affects both EA and SN, except for Social Networking Site Involvement (SNSI), which does not significantly impact EA. Additionally, the findings indicate that BI mediates the relationship between EA and PEB. However, BI does not mediate the SN-PEB relationship, and the link between SN and BI is found to be non-significant. Empirical evidence also suggests that PBC moderates the BI-PEB relationship, with a stronger influence observed under higher levels of PBC and a weaker influence under lower levels. Discussion: These results underscore the complex dynamics between social media factors and pro-environmental behavior. The study concludes that while social media plays a significant role in shaping EA and SN, its impact on EA is not mediated by SNSI. Furthermore, PBC significantly moderates the BI-PEB relationship, highlighting its critical role in PEB. The discussion addresses the implications of these findings, acknowledges the limitations encountered, and suggests potential avenues for future research.

Informing the public about chemical mixtures in the local environment: Currently applied indicators in the Netherlands and ways forward.

The current use of chemicals puts pressure on human and ecological health. Based on the Aarhus Convention, citizens have the right to have access to information on substances in their local environment. Providing this information is a major challenge, especially considering complex mixtures, as the current substance-by-substance risk assessment may not adequately address the risk of co-exposure to multiple substances. Here, we provide an overview of the currently available indicators in the Netherlands to explore current scientific possibilities to indicate the impacts of complex chemical mixtures in the environment on human health and ecology at the local scale. This is limited to impact estimates on freshwater species for 701 substances, impact estimates of four metals on soil organisms, and impacts on human health for particulate matter (PM10) and nitrogen dioxide (NO2) in air. The main limiting factors in developing and expanding these indicators to cover more compartments and substances are the availability of emission and concentration data of substances and dose-response relationships at the population (human health) or community (ecology) level. As ways forward, we propose; 1) developing cumulative assessment groups (CAGs) for substances on the European Pollutant Transfer and Release Register and Water Framework Directive substance lists, to enable the development of mixture indicators based on mixture risk assessment and concentration addition principles; 2) to gain insight into local mixtures by also applying these CAGs to emission data, which is available for soil and air for more substances than concentrations data; 3) the application of analytical non-target screening methods as well as effect-based methods for whole-mixture assessment.

Inhibitory effects of cold plasma-activated water on the generation of advanced glycation end products and methylimidazoles in cookies and mechanistic evaluation using electron paramagnetic resonance.

The inhibitory effects of cold plasma-activated water (PAW) on the formation of AGEs and methylimidazoles in cookies was examined. The results showed that different PAW (parameters: 50 W-50 s, 50 W-100 s, 50 W-150 s, 100 W-50 s, 100 W-100 s, and 100 W-150 s) reduced the contents of AGEs and methylimidazoles, in which the maximum inhibition rates were 47.38% and 40.17% for free and bound AGEs and 44.16% and 40.31% for free and bound methylimidazoles, respectively. Moreover, the mechanisms associated with the elimination of carbonyl intermediates and free radicals was determined by electron paramagnetic resonance (EPR) and high performance liquid chromatography-ultraviolet/visible absorption detector (HPLC-UV/Vis). The results showed the quenching of total free radicals, alkyl free radicals, and HO· by PAW, leading to the suppression of glyoxal and methylglyoxal intermediates. These findings support PAW as a promising agent to enhance the safety of cookies.

Improve the impact property in a novel butt joint of Ti/Al dissimilar metals.

The dissimilar metal welding joint is connected by the metallurgical bond of intermetallic compounds at the interface, which easily causes stress concentration at the interface and cracks continuously along the interface, resulting in low reliability in impact environments. A novel multi-layer plug and bolt connection for TC4/7A52 dissimilar metal butt joints is proposed in this manuscript and analyzes the influence mechanism of the structural design on impact toughness. The impact toughness of the Ti/Al composite butt joint is 30.3 J/cm2, which is 2.6 times that of the 7A52 BM. The layered toughening design significantly reduces stress concentrations for the butt joint at impact for the Ti/Al composite butt joint. Upon impact, the Ti/Al composite butt joint does not fracture continuously at the V-notch and exhibits significant macroscopic plastic deformation. For the microstructure of each TC4 and 7A52 layer in the impact fracture, more intragranular slip systems are activated and show a higher dislocation density. Therefore, this structural design can enable dissimilar metals to absorb more impact energy during the impact process.

Metals in sediment of the upper Great Lakes: Spatial distribution, temporal trends, anthropogenic enrichment, and risk assessments.

Thirteen elements including Al, Ag, As, Co, Cu, Cd, Cr, Fe, Mn, Ni, Se, Zn, and Pb were measured in 107 surface grab sediment samples and 175 segments of eight cores from Lakes Superior, Michigan, and Huron, using inductively coupled plasma mass spectrometry (ICP-MS). Concentrations in Ponar grabs vary considerably among metals and among locations, ranging from the highest median for Fe in Lake Superior (42,000 mg/kg) to the lowest median for Ag in the main Lake Huron (0.05 mg/kg). The inventory at coring sites ranged from 7 × 106 mg/m2 of Fe to 3 mg/m2 of Ag. The background concentrations were estimated from deeper core segments, and enrichment factors (EFs) were calculated with Fe or Al as the reference element. The results show that Al, Fe, Co, Cr, and Mn did not enrich, Ag, Cu, and Ni were present higher than expected from natural sources alone, while Pb, Cd, Se, Zn, and As have been enriched at most sites after European settlement in the region. EFs of most metals are higher for Lake Michigan than the other lakes. However, EF comparison among sampling sites revealed intrinsic problems of this approach for the assessment of human interference. Preliminary risk assessment, conducted by calculating risk quotients, revealed environmental risks of some metals in each lake; however, the results should be interpreted with caution because the approach used is considered to be conservative.

The influence of the addition of titanium oxide nanotubes on the properties of 3D printed denture base materials.

INTRODUCTION: In this study, the effects of adding titanium dioxide nanotubes (TiO2) to 3D-printed denture base resin on the mechanical and physical properties of denture bases were examined for the first time. METHODS: The specimens were digitally created using 3D builder software from Microsoft Corporation through computer-aided design. In accordance with the test specifications for transverse strength, impact strength, hardness, surface roughness, and color stability, specimens were designed and printed with certain dimensions following relevant standards. TiO2 nanotubes (diameter: 15-30 nm and length: 2-3 µm) were added to the 3D-printed denture base resin (DentaBase, Asiga, Australia) at 1.0% and 1.5% by weight. Flexural strength, impact strength (Charpy impact), hardness, surface roughness, and color stability were evaluated, and the collected data were analyzed with ANOVA followed by Tukey's post hoc test (α = 0.05). Field emission scanning electron microscopy (FESEM) and energy dispersive x-ray spectroscopy (EDX) mapping were used to evaluate the dispersion of the nanotubes. RESULTS: Compared with those of the control group (0.0 wt.% TiO2 nanotubes), the average flexural, impact, and hardness values of the 1.0 and 1.5 wt.% TiO2 nanotube reinforcement groups increased significantly. Both nanocomposite groups showed significant color changes compared to that of the pure resin, and there was a considerable reduction in the surface roughness of the nanocomposites compared to that of the control group. CONCLUSION: Adding TiO2 nanotubes to 3D-printed denture base materials at 1.0 and 1.5 wt.% could enhance the mechanical and physical properties of the material, leading to better clinical performance. CLINICAL SIGNIFICANCE: In terms of clinical applications, 3D-printed denture base material has been shown to be a viable substitute for traditional heat-cured materials. By combining this with nanotechnology, existing dentures could be significantly enhanced, promoting extended service life and patient satisfaction while addressing the shortcomings of the current standard materials.

An Instrumented Hammer to Detect the Rupture of the Pterygoid Plates.

PURPOSE: Craniofacial osteotomies involving pterygomaxillary disjunction are common procedures in maxillofacial surgery. Surgeons still rely on their proprioception to determine when to stop impacting the osteotome, which is important to avoid complications such as dental damage and bleeding. Our group has developed a technique consisting in using an instrumented hammer that can provide information on the mechanical properties of the tissue located around the osteotome tip. The aim of this study is to determine whether a mallet instrumented with a force sensor can be used to predict the crossing of the osteotome through the pterygoid plates. METHODS: 31 osteotomies were carried out in 16 lamb skulls. For each impact, the force signal obtained was analysed using a dedicated signal processing technique. A prediction algorithm based on an SVM classifier and a cost matrix was applied to the database. RESULTS: We showed that the device could always detect the crossing of the osteotome, sometimes before its occurrence. The prediction accuracy of the device was 94.7%. The method seemed to be sensitive to the thickness of the plate and to crack apparition and propagation. CONCLUSION: These results pave the way for the development of a per-operative decision support system in maxillofacial surgery.

Enhanced boxing punch impact with silicone cushioning.

Introduction: Elastic cushioning materials protect human tissue from injury by absorbing impact energy and delaying its transfer. However, the potential compromise in force delivery to the hitting target remains unknown. Methods: To examine if silicone cushioning compromises punch force delivery to a hitting target, a double-blind crossover trial with 12 elite boxers was conducted following material tests. Each boxer delivered five maximal punches under two conditions: silicone-hand wrapping and gauze-hand wrapping, in counterbalanced order, with a 3-day interval between sessions. Force distribution along the Z-axis indicated the punch's intended direction, while forces along the X and Y axes represented force dissipation toward unwanted direction. Results: The material tests (based on ASTM International, West Conshohocken, PA, USA) demonstrated substantially higher compression to disruption for silicone than gauze of similar thickness. During the punching trials, the silicon-based hand wrapping exhibited slightly higher total force production (436 ± 33 N vs. 372 ± 12 N, p < 0.001) than the gauze-based hand wrapping. Moreover, force wastage, calculated as the sum of forces along the X and Y axes vs. the total force produced in percentage, was notably lower for silicone material (2.0% wastage) compared to gauze (3.8% wastage) (p < 0.001). The use of silicone materials lengthened the contact time between the punching fist and the hitting target from 35 ms to 50 ms (p < 0.001). Conclusion: The elastic cushion does not compromise the force delivery of the boxing glove to the hitting target. Instead, it appears to allow for additional maneuvering time for alignment during the fist-target contact with higher impact.

Percentage ofpatients with access to treatment, acquisition cost of upadacitinib 30 mg andprevalence of MS-AD were the most influential parameters in the budget impactresults. At week 16, upadacitinib 30 mg was associated with the lowest numberneeded to treat and the lowest cost per responder for all outcomes. CONCLUSION: The introduction of upadacitinib in MS-AD treatment was associated with modestsavings for the social security and private payer budget in Argentina.

Exploring Greek Population Attitudes Towards Using Health-Related Websites for Managing Their Health.

The last few years the Internet has evolved into a prominent information source for many people worldwide. Latest research has shown that an ever increasing number of citizens and patients go online in order to access health information and seek support in managing their health, including understanding their condition, adopting life-saving lifestyle adjustments and keeping up with treatment or aftercare guidelines. Due to this rise on the demand of online health information, health-related sites have increased substantially, with each one of them striving to maintain the most comprehensive and reliable source of health and medical information on the Internet. This paper presents a survey conducted among Greek population aiming at exploring participants general attitudes towards using the Internet to access health information as well as their views regarding a specific Greek health-related website, namely Iatronet. To this end, an online Greek version of eHealth Impact Questionnaire has been used which was developed using RedCAP platform.

Aliphatic and polycyclic aromatic compounds in coal and coal-based solid wastes: Relationship with coal-forming paleoenvironment and implications for environmental pollution.

In this study, coal and coal-based solid wastes (coal gangue, fly ash, bottom ash, desulfurized gypsum and tar residue) were collected from major coal mines, power plants and coking plants in Lianghuai mining area (LH), China, and were analyzed for 76 polycyclic aromatic compounds (PACs), 27 n-alkanes and 2 isoprenoids (phytane and pristane). The total n-alkanes concentrations and ∑76 PACs in raw coals (640 ± 600 and 180 ± 87 µg/g) were higher than those in coal-based solid wastes (47 ± 40 and 24 ± 25 µg/g), but were lower than those in tar residue (3700 and 63,000 µg/g). It was discovered that the depositional paleoenvironment in LH was mostly a lacustrine and freshwater environment with oxidizing conditions and mixed organic matter input, but the Huainan coalfield had stronger oxidizing conditions and more input of terrestrial organic matter than that of the Huaibei coalfield. Alkylated PACs made up 56 ± 12 % of the ∑76PACs in raw coals, whereas solid wastes mainly consisted of 16 EPA PAHs (66 ± 16 %). Coal combustion and gangue weathering altered the structural properties of n-alkanes and PACs, resulting in a significant loss of n-alkanes and PACs, a higher proportion of parent PACs, and an increased abundance of short n-alkanes in the products (No apparent change of n-alkanes composition was observed through gangue weathering). The toxicity of PACs in raw coal and its solid wastes in LH from high to low was tar residue, raw coal, coal gangue, and coal-fired products. This investigation further confirmed that traditional diagnostic ratios may distort source information, and that they should not be used to assess PACs sources from raw coal particles or coal gangues, but rather to identify combustion sources near the point source. In addition, Retene/(Retene + Chrysene) < 0.03 may indicate direct contamination of raw coal particles.

Economic Evaluation of an Integrated Care Program Compared to Conventional Care for Patients With Chronic Kidney Disease in Rural Communities of Thailand.

Introduction: An integrated care program for chronic kidney disease (CKD) in Thailand has shown its effectiveness in delaying the decline in kidney function, as evidenced by the Effectiveness of Integrated Care on Delaying Progression of Stages 3 to 4 CKD in Rural Communities of Thailand (ESCORT-1) randomized control trial and the ESCORT-2 prospective cohort study. Designed for sustainability within the primary healthcare system, the program optimizes the use of the existing workforce by fostering collaboration among local multidisciplinary care teams (MDCTs) and community care networks (CCNs). Methods: A Markov model with a lifetime horizon was used to conduct a cost-utility analysis from a societal perspective. Individual participant level data from ESCORT studies, national registries, and relevant literature were used to estimate model parameters. A budget impact analysis from the payer's perspective was also assessed over a 5-year period. Results: The integrated care program yielded a dominant result with 1.84 quality-adjusted life years (QALYs) gained with "less" lifetime cost, resulting in a negative incremental cost-effectiveness ratio (ICER). Probabilistic analysis showed that the intervention being cost-effective almost 100% of the time at the local willingness-to-pay threshold. The intervention maximized cost-effectiveness when delivered as early as possible, both in terms of age and stage. The budget impact analysis estimated that the introduction of the intervention could save about 7% of the Thai government's total health expenditure or 205 billion Thai-Baht ($5.9 billion) over 5 years with cost savings beginning from the third year onwards. Conclusion: The integrated care program for CKD offers potential benefits and cost savings for patients, caregivers, and payers. Future efforts should focus on the screening and implementation processes across various regions and healthcare settings.

Psychosocial and Sexual Aspects of Female Genital Circumcision in a Sample of Kurdish Women in the Kurdistan Region of Iraq.

BACKGROUND AND AIM: Female genital circumcision (FGC), a prevalent practice in the Kurdistan Region of Iraq, has significant psychosocial and sexual implications for affected women. Therefore, this study aimed to investigate these impacts among circumcised and non-circumcised Kurdish women. METHOD: This comparative study was conducted from January 2 to June 27, 2023, at the Al Mesalla for Human Rights Improvement organization in Erbil, Iraq. Purposive sampling was used to collect data using a comprehensive questionnaire. The questionnaire included demographic information, the Depression, Anxiety, and Stress Scale (DASS-21), the Rosenberg Self-Esteem Scale (RSE), and the New Sexual Satisfaction Scale-Short Form (NSSS-S). Statistical analysis was performed using SPSS version 26 (IBM Corp., Armonk, NY), with frequency and percentage used for categorical variables and mean and standard deviation for quantitative variables. Independent sample t-tests and Chi-square tests were conducted to compare groups. A p-value of less than 0.05 was considered statistically significant. RESULTS: A total of 772 participants were enrolled in the study, including 382 circumcised and 390 non-circumcised women. The study found significant differences between the two groups in terms of depression, self-esteem, and sexual satisfaction. Circumcised women had higher mean scores for depression (12.19 ± 5.6 vs. 10.68 ± 5.3), lower mean scores for self-esteem (24.4 ± 12.1 vs. 30.3 ± 10.1), and lower mean scores for sexual satisfaction (52.4 ± 24.6 vs. 67.6 ± 20.4) compared to non-circumcised women (all p < 0.001). CONCLUSIONS: The study demonstrated that FGC is associated with higher levels of depression, lower self-esteem, and lower sexual satisfaction among Kurdish women. It is recommended for policymakers and healthcare providers to develop targeted interventions to address the psychosocial and sexual health needs of circumcised women in the Kurdistan Region of Iraq.
