The Resilience Factor: Examining its Potential to Alleviate Shame and Guilt in School Bullying.

School violence, in particular bullying by peers, has become a problem on the public agenda. In the context of bullying, children exposed report high levels of shame and guilt which increase victimization since involves a humiliating experience associated with the lack of acceptance by the peer group and can negatively affect mental health. Both emotions have been previously studied in peer violence context. Now we aim to examine resilience as a potential factor to alleviate shame and guilt in school bullying. We conducted a study to test if resilience mediates the feeling of shame and guilt effect of being exposed to bullying; that is, if resilience entails protective behaviors that favour the dissipation of the risk of feeling shame and guilt when exposed to direct violence in school. First, we adapted to Mexican Spanish the research instrument Short Version of the State Shame and Guilt Scale (SSGS-8, Cavalera et al., 2017)-; then we conducted a quantitative, explanatory, cross-sectional approach study; both were carried out in two different non-urban high schools near the city of Monterrey, Mexico, randomizing groups. We found through a moderated mediation analysis that resilience is a key piece to transform shame and practically alleviate negative school violence consequences the indirect effect of resilience on the relationship between direct violence in school and shame was moderated by gender, better for boys than for girls. As its presence restrain shame in those who have been exposed to direct violence in school, it is important to strengthen resilience in adolescents. Promoting the development of shame resilience in adolescents is crucial to prevent them from questioning whether something is wrong with them when exposed to violence. We must continue making efforts to eradicate violence in schools through prevention programs and public policies.

Foot care behaviours and associated factors among patients with type 2 diabetes: A cross-sectional study.

As numerous studies highlighted the importance of maintaining proper foot care (FC) behaviours among individuals with diabetes to prevent complications, we sought to assess FC behaviours among patients with diabetes and to identify the factors associated with the practice of diabetic FC. We used a cross-sectional design and collected data through self-reported questionnaires administered to a sample of 586 patients from five medical centres. We conducted descriptive and inferential analyses to explore the relationships between potential risk and protective factors and FC behaviours. Overall, 429 individuals (73.2%) had good FC behaviours, while 157 (26.8%) displayed poor FC behaviours. Furthermore, we identified eight influencing factors on FC behaviours, including smoking status, the availability of a caregiver, the presence of diabetic foot ulcers, amputation history, FC knowledge, subjective norms in diabetes self-care behaviour, diabetes-related stress, and quality of life index values. The logistic regression analysis showed that current smokers were 60% less likely to practice good FC compared to non-smokers (odds ratio (OR) = 0.40; 95%; confidence interval (CI) = 0.22-0.73). Having a caregiver decreased the likelihood of practicing good FC by 50% (OR = 0.52; 95% CI = 0.33-0.84), while having diabetic foot ulcers doubled it (OR = 2.65; 95% CI = 1.26-5.54). Additionally, more FC knowledge increased the likelihood by 20% (OR = 1.21; 95% CI = 1.10-1.33), and higher diabetes-related stress increased it by 1.03 times (OR = 1.03; 95% CI = 1.02-1.05). Our findings underscore the interplay of various factors influencing FC behaviours among individuals with diabetes and call for targeted interventions and tailored strategies to improve FC practices in this vulnerable population.

Biologically Synthesized Gold Nanoparticles with Enhanced Antioxidant and Catalytic Properties.

Increasing levels of reactive oxygen species generate oxidative stress in the human body that can lead to various medical conditions. The use of nanomaterials exhibiting antioxidant properties may prevent these effects. The biological synthesis of metallic nanoparticles using plant extracts with antioxidant properties can offer benefits due to their active compounds. The used extracts contained reducing and stabilizing agents, which were shown to be transferred onto the gold nanoparticles, functionalizing them. Herin, we report a gold nanoparticle synthesis by eco-friendly biological methods (b-AuNPs) using extracts of sea buckthorn, lavender, walnuts, and grapes, obtained through ultrasound-assisted extraction and pressure-enhanced extraction. The obtained b-AuNPs were characterized by UV-Vis and FTIR spectroscopies and visualized using transmission electron microscopy. The catalytic and scavenging effect of the b-AuNPs towards H2O2 (as reactive oxygen species) was evaluated electrochemically, highlighting the protective behavior of b-AuNPs towards lipid peroxidation. All experiments demonstrated the stability and reproducibility of prepared b-AuNPs with enhanced antioxidant and catalytic properties, opening a new perspective for their use in biomedical applications.

The “Cycle” of HIV: Limits of Personal Responsibility in HIV Vulnerability Among Transgender Adolescents and Young Women in Lima, Peru

Globally, transgender women (TW) face a high burden of the HIV epidemic. In Peru, HIV prevalence among TW rises at age 25, indicating a need to understand HIV vulnerability as adolescents reach adulthood. The life course of TW is often marked by abuse, discrimination and poverty fueled by transphobic stigma. Approaches to the HIV epidemic among TW and adolescents emphasize problem behaviors such as unprotected sex and substance. However, there has been a call for HIV research and interventions to understand and leverage community strengths. This qualitative study utilized a transgender-oriented, strength-based, intersectional and feminist approach to understand the strengths and protective health behaviors among 17 transgender adolescents and young women (TAYW) age 16–24 in Lima, Peru. Most participants re-located to Lima from the Amazon due to familial rejection, and engaged in obligatory sex work. TAYW demonstrated self-knowledge, motivation for education, efforts to secure employment, strong community networks, legal advocacy, avoiding problem substance use, HIV knowledge and condom use. However, strengths were impeded by multi-level barriers such as familial physical abuse, educational discrimination, and sexual assault which led to increased HIV vulnerability. We created a conceptual model of the “cycle” of HIV to describe the limits of personal responsibility within a vulnerable community denied access to family, education, employment and human rights. We recommend researchers, clinicians and public health workers follow the lead of TAYW at the frontlines of the HIV epidemic, and support beloved communities and enabling environments which may permit protective behaviors to mitigate HIV vulnerability.

People with long-term conditions are more adherent to protective behaviours against infectious disease

ObjectivesTo investigate the relationship between long-term condition (LTC) status and adherence to protective behaviours against infectious disease (face covering, physical distancing, hand hygiene). Study designRepresentative cross-sectional observational survey in summer 2020 in Scotland. MethodsIndependent variable is LTC status (LTC, disability, no LTC); dependent variable is adherence to protective behaviours (face covering, hand hygiene, social distancing); moderator variables are age, gender and area deprivation; mediator variables are perceived threat and psychological distress. P values of p < 0.05 were taken as statistically significant. Results3972 participants of whom 2696 (67.9 %) indicated not having a LTC. People with no LTC had lowest adherence to protective behaviours, perceived threat and psychological distress. Age did not moderate the relationship between LTC status and adherence; females were more adherent than males and this gender difference was greater in people with disability compared to people with no LTC; adherence was greater for people with a LTC in the more deprived areas compared to the least deprived areas whereas adherence in those with no LTC was not related to area deprivation; threat appraisal partially mediated the relationship between having a LTC or disability and adherence; psychological distress did not mediate the relationship between LTC status and adherence. ConclusionsThis study addresses a gap in evidence about protective behaviours of people with LTCs. Perceptions of threat may be useful intervention targets against winter flu and during future pandemics in order to protect people with LTCs who are one of the most vulnerable groups of the population.

Performance Under Fire: Older Adult Cognitive Risks and Protections Under Heat Strain.

Although extreme heat events disproportionately affect older adults and the importance of cognition is known, research examining older adult cognition under heat stress is limited. This study examines the relationship between risk/protective factors and heat strain on older adult cognition, employing a social-ecological model. Retrieved from the 1996-2016 waves of the Health and Retirement Study, our study used older adults aged 50 and older and their spouses residing in the United States. Individual-fixed effects models estimated changes in cognition as measured by fluid and crystallized intelligence scores in response to extreme heat days. This study further estimated interactions of extreme heat with protective/risk factors for cognition (i.e., education, physical activity, social engagement, and genetic risk for Alzheimer's disease). Our results demonstrated that extreme heat days were associated with fluid but not crystallized intelligence scores. Educational attainment, mild physical activity, and social contacts with children moderated this relationship. Furthermore, Alzheimer's disease polygenic scores moderated the correlation between extreme heat days and crystallized intelligence scores. An increasing frequency of extreme heat events and an aging population globally highlight the need for policies and interventions building resiliency in older adults. Actions promoting the protective modifiable behaviors to older adult cognition identified by our study can lead to healthier individuals and communities.

Implicit attitudes toward obesity-related cues and their relation to body mass index, psychosocial functioning, and health behavior.

Differences in automatic cognitive processes exist among individuals with overweight and obesity, thus there is a need to expand our conceptualization of overweight and obesity to emphasize the predictive utility of these automatic processes, rather than focusing solely on behavioral outputs. Implicit association tests (IATs) may afford a noninvasive method of examining automatic preferences that might contribute to overweight and obesity; namely, preferences for unhealthy foods and sedentary behavior versus healthy foods and physical activity. The purpose of the current study was to examine whether implicit attitudes toward foods and physical activity differed based on body mass index (BMI) status. The relationships between implicit attitudes and key psychosocial factors and health behaviors were also examined. Participants (N = 127) included undergraduate students with an average age of 19.05 years old (SD = 1.52). Average BMI of the sample was 24.20 (SD = 4.93); 33.8% met criteria for overweight or obesity. Participants completed an IAT and questionnaires. There were no differences in implicit preferences based on BMI or BMI status. Overall, the sample demonstrated implicit preferences for healthy foods and active words, and preferences were not linked to the corresponding behavioral outputs, though preferences were linked to various indices of emotion and emotion regulation. Future research should explore an extended model to examine how implicit preferences might impact intentions to engage in protective versus risky obesity-related health behaviors, and the various psychosocial factors that might impact the translation of those preferences and intentions in actual behavioral outputs.

The driving effect of experience: How perceived frequency of floods and feeling of loss of control are linked to household-level adaptation

This study examines how perceived and remembered flood experiences, measured as frequent flood experience (FFE) and loss of control experience (LCE) during the last flood, are related to individual protection motivation. Protection Motivation Theory (PMT) builds the theoretical basis of this study, describing protection motivation as a result of threat and coping appraisals. To evaluate the relationship between flood experience and protective behavior, we applied structural equation modeling using survey data from 2020 conducted in Saxony, Germany (n = 1,884). Four main conclusions can be drawn: first, both applied measures of experience, FFE and LCE, are positively associated with threat appraisal, leading to a positive link to protection motivation. Second, FFE and LCE negatively relate to coping appraisal, culminating in an overall negative relationship with protection motivation. Third, FFE has a stronger direct link to protection motivation, and LCE has a stronger indirect link via threat and coping appraisals. Fourth, the relationship between LCE and threat appraisals decreases over time, while the relationship between FFE and threat appraisals does not diminish. The study underscores the importance of considering individual flood experience to understand protective behavior in the context of increasing flood frequencies. Moreover, including affective measures of experience, such as LCE, can improve our understanding of why some flood-prone people undertake protective measures whereas others do not.

Social Vulnerability and Compliance With World Health Organization Advice on Protective Behaviors Against COVID-19 in African and Asia Pacific Countries: Factor Analysis to Develop a Social Vulnerability Index.

COVID-19 protective behaviors are key interventions advised by the World Health Organization (WHO) to prevent COVID-19 transmission. However, achieving compliance with this advice is often challenging, particularly among socially vulnerable groups. We developed a social vulnerability index (SVI) to predict individuals' propensity to adhere to the WHO advice on protective behaviors against COVID-19 and identify changes in social vulnerability as Omicron evolved in African countries between January 2022 and August 2022 and Asia Pacific countries between August 2021 and June 2022. In African countries, baseline data were collected from 14 countries (n=15,375) during the first Omicron wave, and follow-up data were collected from 7 countries (n=7179) after the wave. In Asia Pacific countries, baseline data were collected from 14 countries (n=12,866) before the first Omicron wave, and follow-up data were collected from 9 countries (n=8737) after the wave. Countries' socioeconomic and health profiles were retrieved from relevant databases. To construct the SVI for each of the 4 data sets, variables associated with COVID-19 protective behaviors were included in a factor analysis using polychoric correlation with varimax rotation. Influential factors were adjusted for cardinality, summed, and min-max normalized from 0 to 1 (most to least vulnerable). Scores for compliance with the WHO advice were calculated using individuals' self-reported protective behaviors against COVID-19. Multiple linear regression analyses were used to assess the associations between the SVI and scores for compliance to WHO advice to validate the index. In Africa, factors contributing to social vulnerability included literacy and media use, trust in health care workers and government, and country income and infrastructure. In Asia Pacific, social vulnerability was determined by literacy, country income and infrastructure, and population density. The index was associated with compliance with the WHO advice in both time points in African countries but only during the follow-up period in Asia Pacific countries. At baseline, the index values in African countries ranged from 0.00 to 0.31 in 13 countries, with 1 country having an index value of 1.00. The index values in Asia Pacific countries ranged from 0.00 to 0.23 in 12 countries, with 2 countries having index values of 0.79 and 1.00. During the follow-up phase, the index values decreased in 6 of 7 African countries and the 2 most vulnerable Asia Pacific countries. The index values of the least vulnerable countries remained unchanged in both regions. In both regions, significant inequalities in social vulnerability to compliance with WHO advice were observed at baseline, and the gaps became larger after the first Omicron wave. Understanding the dimensions that influence social vulnerability to protective behaviors against COVID-19 may underpin targeted interventions to enhance compliance with WHO recommendations and mitigate the impact of future pandemics among vulnerable groups.

Operando facet control of hydrophobic iron nitride nano-coral for surface protection via field-modulated plasma strategy

A facile facet reconfiguration has been considered as an essential issue for nitride coating in promoting surface protection behaviour. Compared to physical-chemical methods to achieve heterogeneous coating, plasma nitridation strategy is regarded as a favourable technique to in-situ deliver nitride protecting layer, but it is difficult to precisely control surface framework through plasma technique due to complicated interaction environment. To simply achieve nitride coating with favourable surface protection behaviour, we design a novel auxiliary insulator-confined plasma system to directly achieve hydrophobic iron nitride nano-coral (hFeNC) with desirable corrosion- and wear-resistant properties by controlling surface heating process during plasma nitridation. The resultant hFeNC nano-framework delivers corrosion rate of 1.2 mpy, 4- and 9-times lower than that of solid iron nitride film (sFeN) via normal plasma and initial Fe in NaCl condition, respectively. Operando plasma diagnostics along with numerical simulation further confirm the effect of surface heating on typical plasma parameters as well as the iron nitride nano-frameworks, indicating surface heating as the key factor responsible for the favourable surface protection coating.

Investigating the Impacts of Different Warning Modalities on Individual’s Risk Perception and Response Behaviors Through a Virtual Reality Experiment

With the impacts of global climate change, natural hazards are growing in, number and intensity, affecting American communities. Effective risk, communications have been identified as one of the best ways to prepare, for and mitigate natural hazards. Current natural hazard warning systems, remain inadequate since they are generalized and abstract. To address, this issue, this study explores how different modalities—specifically, haptics, audio, and text affect individuals’ risk perceptions and their, subsequent protective behaviors. This study developed a virtual reality, system and conducted a human-subject experiment with 24 participants, related to tornado risk communication. Task performance was measured, based on the time in the shelter, level of trust, expectations, and, intention to shelter. Risk perception and cognitive load data were, collected using well-established questionnaires. The research results, found that haptic-enhanced warnings were more effective in prompting, risk perceptions and protective actions compared to audio and static text, messages.

Analysis of residents’ health and willingness to pay for environmental protection in China

Health and environmental issues have become pressing global problems that affect human society's sustainable development. Residents are not only practitioners but also direct beneficiaries of ecological protection and play a crucial role in maintaining ecological and environmental health. Health, as the basis of residents' behavioral choices, influences residents' behavior toward ecological and environmental protection. This study aims to investigate how health factors profoundly affect residents' willingness to pay (WTP) for environmental protection and reveal the intrinsic connection between health and environmental protection behavior. The 2017 China Household Finance Survey (CHFS) data and the ordered probit model were used to determine that improving residents' health greatly increases their willingness to protect the environment and passes a number of tough tests. In addition, the promotion effect of health on residents' WTP for ecological protection is markedly heterogeneous, especially in younger residents who do not have children. Therefore, we suggest to policymakers and national governments a range of countermeasures and suggestions to enhance health education, safeguard public health, and promote ecological protection education.

Fennel (Foeniculum vulgare Mill.) essential oil: The chemical profile, biological activity, and utilization of the commercial products

Laboratory-isolated essential oils are commonly used in experiments regarding their utilization as natural antioxidant and antimicrobial agents. This study analyzed commercially available essential oils (Serbian-FSR and Russian-FRU) of fennel (Foeniculum vulgare Mill.) and added to the pork patties to investigate their possible role as natural antioxidant and antimicrobial agents. Chemical analysis of the samples showed significant differences in profiles caused by geographical origin and other environmental factors. The main compound in both samples was trans-Anethole, but it had a much higher content in Serbian oils. On the contrary, Russian oil had a high portion of anisaldehyde and linalool. These diversities are the main reason for thermal behavior and biological activity differences. The thermal analysis has shown that FSR had a crystalline form in the solid state, while FRU had an amorphous form. During heating, in FSR, a single-step weight loss was detected, while in FRU, a two-step weight loss was observed, indicating that, in addition to evaporation, components in FRU interacted with each other, forming lesser volatile molecules. After adding pork patties, Russian oil showed higher potency and better protective behavior than Serbian oil. Moreover, mixtures of these oils were added to the patties samples, and results showed higher potency when compared to individual oil samples. This indicated that minor compounds from both oils interacted and synergistically acted to prolong the shelf life of the meat samples. Commercial essential oils could be successfully utilized to prolong shelf life and provide additional intake of natural compounds significant for the human diet.

Predicting households’ attitudes and product adoption intentions

PurposeThe present study aims to examine the households’ attitudes and intentions to adopt an indoor air purifier against the smog crisis in India by using a comprehensive theoretical framework based on the combination of the Protective Action Decision Model (PADM) and the Theory of Planned Behavior (TPB). The United Nations Sustainable Development Goals (SDGs) 2030 also emphasized ensuring a healthy and safe life, especially by achieving SDG-3, SDG-11 and SDG-13.Design/methodology/approachUsing purposive sampling, the data were collected through a survey questionnaire distributed to 382 households, and study hypotheses were assessed by using partial least squares structural equation modeling employing SmartPLS.FindingsThe results revealed that mental health risk perception (MHRP) was the most influential determinant of households’ attitudes toward adopting air purifiers, followed by smog knowledge, physical health risk perception (PHRP), information seeking and product knowledge. Notably, results revealed that households’ attitude is a leading determinant of their adoption intention toward the air purifier compared to subjective norms (SN) and perceived behavioral control (PBC).Originality/valueTo the best of the authors’ knowledge, the present study is the first to provide new insights into an individual’s protective behavior response toward ecological hazards by examining the households’ adoption intention toward the air purifier against the smog crisis using PADM and TPB model inclusively. In addition, the present study analyzes the impact of both PHRP and MHRP on individuals’ protective behavior separately. Also, this study provides theoretical contributions and important practical implications for the government, manufacturers and air purifier sellers.

Tripartite Evolutionary Game Analysis of Product Quality Supervision in Live-Streaming E-Commerce

With the rapid development of information technology, live-streaming e-commerce has risen rapidly as a new business model. However, product quality problems that exist in the development of live-streaming e-commerce continue to emerge. The influence of strategic interactions between social media influencers, live-streaming e-commerce platforms, and consumers on product quality deserves to be studied. Therefore, this paper constructs a tripartite game model of “social media influencers–the live-streaming e-commerce platform–consumers” and analyzes the dynamic evolution process of the strategy selection among subjects and influencing factors by using evolutionary game theory. This study shows that products with high functional value are more likely to stimulate consumer rights protection behavior, prompting social media influencers to shift from lax to strict quality control. But when the emotional value is high, consumers are more inclined to give up on defending their rights, which leads to the maintenance of lax quality control, and the platform supervision will be weakened accordingly. Moreover, less quality differences motivate social media influencers to choose lax quality control. An increase in quality differences will promote a shift from an equilibrium strategy to strict quality control. However, if the penalty of the platforms is not strong enough, this strategic shift will not happen. In addition, a high percentage of platform commissions can encourage influencers to implement strict quality control, while platforms can maintain weak supervision. This study’s findings provide valuable guidance for understanding and managing product quality issues in live-streaming e-commerce. In the future, the government will be considered a new player in the game in studying the impact of its policies on product quality in live-streaming e-commerce.

The radiation protection behavior of medical workers: A scoping review protocol.

Radiation exposure in medical settings stands as the primary source of artificial radiation, compounded by the yearly rise in healthcare worker numbers. Ensuring radiation protection is crucial for safeguarding their occupational health. Nevertheless, existing studies on radiation protection behavior exhibit considerable heterogeneity due to various factors. This scoping review aims to explore the current status of research on radiation protection behavior and identify research gaps, intending to guide future research directions. The scoping review will follow the Arksey and O'Malley framework and the Joanna Briggs Institute methodology. A systematic search will be conducted across English databases including PubMed, Web of Science, Embase, and Medline, as well as Chinese databases such as CNKI, Wanfang, VIP, and China Biomedical Literature Database. Two independent reviewers will screen the studies based on predefined eligibility criteria and extract the data. Any disagreements will be resolved through discussion by a third reviewer. The review will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews. A stakeholder consultation will provide an opportunity to validate the findings and address any potential gaps in the article. In this scoping review, all types of studies will be considered. The effectiveness of the methodological quality of the included studies will not be reported, which may lead to some studies of poor quality being included. Only studies published in English or Chinese after 2010 will be considered in this review, potentially leading to the omission of relevant papers.

Unveiling the nexus! Understanding knowledge issues, animal contact patterns and interaction of health care providers in the context of monkeypox and COVID-19 during monkeypox outbreak 2022

Background A monkeypox (MPOX) outbreak occurred in May 2022. On June 3, 2022, the WHO Blueprint organized a consultation on MPOX research knowledge gaps and priority research questions because the engagement of health care providers (HCPs) in providing accurate information and the public's motivation to adapt protective behaviour were crucial. Thus, we conducted this study to explore the knowledge issues, animal patterns, and interactions of HCPs in the context of MPOX and COVID-19 during the MPOX outbreak. Methods We conducted a cross-sectional web-based survey among 816 HCPs working in governmental health facilities from many countries, mainly Syria, Egypt, Saudi Arabia, and Cameroon, in September 2022. Results Four hundred and sixty (56.37%) were aged between 18 and less than 35 years old. About 34.44% were physicians, while only 37.25% worked on the frontlines with patients. 37.99% and 5.88% received vaccinations against chickenpox and MPOX, respectively. In the meantime, 55.39% had taken courses or training programmes regarding COVID-19. Regarding knowledge-seeking behaviours (KSBs) about COVID-19, 38.73% were through passive attention, while only 28.8% got their information through active search. Most of the participants (56.86%) had a moderate level of knowledge regarding COVID-19. Only 8.82% had courses or training programmes regarding MPOX. Regarding KSB about MPOX, 50.86% were obtained through passive attention, while only 18.01% and 23.04% got their information through active and passive search, respectively. Most of the participants (57.60%) had a poor level of knowledge regarding MPOX. The regression analysis of the MPOX knowledge score revealed that individuals working on the frontlines with patients and those who had training programmes or courses were shown to have a higher score by 1.25 and 3.18 points, respectively. Conclusions The studied HCPs had poorer knowledge about the MPOX virus than they did about the SARS-CoV-2 virus. Training programmes and education courses had an impact on their knowledge.

The effect of phosphorous content on the microstructure and localised corrosion of electroless nickel-coated copper

A detailed microstructural and electrochemical analysis of electroless nickel phosphorous (NiP) coatings with P contents of 13.2 ± 1.2 wt%, 12.9 ± 0.7 wt%, and 8.3 ± 0.8 wt% on a copper substrate was performed to study the corrosion behaviour of electroless NiP/Cu systems. The P content of the electroless NiP coatings plays an essential role in the microstructure of the coatings in terms of crystallinity. The crystallinity variations, representing the extent of crystalline and amorphous phases within the material, with P content, affect the local electrochemical characteristics and, hence, the corrosion protection behaviour of electroless NiP coatings. The coatings with the highest P content showed the best corrosion performance in a 3.5 wt-% NaCl solution. In contrast, the surface of the electroless NiP coatings with low P content is more susceptible to corrosion due to the presence of locations with heterogeneous electronic properties that initiate localised corrosion. Microgalvanic interactions with a high cathode-to-anode surface ratio govern the localised corrosion kinetics of the low P-content samples. A high concentration of nodule boundaries and/or other existing structural defects on the surface serve as anodic sites, whereas the remainder of the surface serves as cathodic sites.
