Background: Despite the significant global disease burden associated with HPV infection, the vaccination coverage among female college students in China remains suboptimal. This study aimed to examine HPV vaccination coverage, knowledge levels, and determinants influencing vaccination behavior among female college students in northern China, utilizing the Health Belief Model (HBM) as a theoretical framework. Methods: A cross-sectional online survey was conducted from December 2024 to January 2025, involving 4076 female students from six universities in Jinan, China. The participants were categorized into three groups: vaccinated (VG), willing-to-vaccinate (WTG), and unwilling-to-vaccinate (UTG). Data on sociodemographic characteristics, HPV knowledge, health beliefs, and vaccination behavior were analyzed using ANOVA, chi-square tests, correlation analysis, and multivariate logistic regression. Results: The vaccination rate was 18.11%, with 40.19% expressing willingness to vaccinate and 41.71% expressing unwillingness. Vaccinated students demonstrated higher levels of HPV knowledge (6.66 ± 2.67 compared to 4.76 ± 3.10 in the UTG, p < 0.001) and were predominantly from urban areas (OR = 0.64, p < 0.001). The key determinants of vaccination uptake included perceived benefits (OR = 1.54, p < 0.001), perceived barriers (OR = 3.34, p < 0.001), self-decision-making ability (OR = 1.80, p < 0.001), and social motivation (OR = 0.21, p < 0.001). Notably, increased knowledge was associated with vaccine hesitancy in the WTG group (OR = 0.45, p < 0.001), indicating that information overload may adversely affect decision-making processes. Structural barriers, such as cost (42.63%), safety concerns (46.59%), and misconceptions (e.g., 57.76% cited “no sexual activity” as a reason for refusal), significantly impeded vaccine uptake. Conclusions: The low coverage of HPV vaccination is indicative of deficiencies in knowledge, socioeconomic disparities, and cultural perceptions. Tailored interventions should focus on educational efforts to correct misconceptions, provide subsidized access to vaccines, and implement empowerment strategies that enhance self-efficacy and informed decision-making. Policymakers should incorporate these findings into national cervical cancer prevention programs to address the gap between vaccination intention and behavior among young women in China. Full article

Objective: Malnutrition remains a global challenge to child development, with urban slums in India experiencing high rates of protein deficiency. This study aimed to evaluate the effectiveness of a low-cost, fish bycatch-derived protein supplement in supporting catch-up growth among malnourished children. Methods: Using the Sustainable Community Partnership and Empowerment (SCOPE) model, we implemented a 90-day intervention with daily 10 g of Advanced Protein Powder (APP), produced from underutilized fish bycatch. Forty-six malnourished children (aged 3–6) from Bengaluru slums were randomized into a Control group receiving caloric support or an APP supplement group. Growth indicators, cognition, and caregiver perspectives were assessed. Results: Children receiving the APP supplement showed a significant increase in the weight-for-age percentile (underweight), rising by 7.59%, compared to 0.59% in the Control group (p = 0.02185). Muscle growth, measured by mid-upper arm circumference, also improved significantly in the APP Group (p < 0.05). In the first month, APP supplementation led to a significant height gain of 1.86 cm (p < 0.001), whereas the Control group showed no change (p > 0.05). Additionally, APP supplementation enhanced cognitive function, visual processing, short-term memory, and planning ability, with sustained effects at six months (p < 0.05). Caregivers reported noticeable improvements in children’s vitality, appetite, focus, and engagement in social and learning activities. Conclusions: Bycatch-derived protein supplementation, implemented through the SCOPE model, enhanced physical growth, behavior, and cognition in malnourished children in urban slums. Future studies should investigate the long-term effects, scalability, and adaptability of this sustainable solution for addressing child malnutrition. Full article

The Industry–Finance Collaboration Pilot (IFCP) integrates governmental green guidance with digital collaboration platforms to promote non-equity-based cooperation between industrial and financial sectors. Using a Difference-in-Differences (DID) approach and a sample of A-share listed industrial firms on the Shanghai and Shenzhen Stock Exchanges from 2011 to 2023, this study examines the IFCP’s impact on corporate green innovation (GI). Results show that the IFCP increases the number of green patent applications by 7.5% on average, indicating its effect in stimulating GI. This effect operates through two main mechanisms. First, under governmental green guidance, the IFCP encourages local green fiscal subsidies, increases green investor participation, improves environmental information disclosure, and lowers agency costs. Second, through digital finance empowerment, it mitigates information asymmetry and transaction costs in financial activities, thereby reducing credit costs and enhancing firms’ access to green credit. The effect of the IFCP on GI is more pronounced in regions with stricter environmental regulation, in pollution-intensive industries, and among firms with smaller asset sizes. Further analysis indicates that the IFCP primarily stimulates tactical, low-value GI driven by compliance or opportunistic motives, rather than promoting substantive, high-quality innovation. This study provides empirical evidence and policy insights into how governmental green guidance and digital finance empowerment can jointly promote green industrial development. Full article

Since COVID-19, there has been an increase in the utilization of food banks owing to a number of factors, including a reduction in household income due to job losses and an increase in the cost of living, which has affected people on low incomes. In this paper, we explain how people that are in need of assistance and have limited knowledge of service provision can be remotivated through regaining their self-esteem. This is achieved through various forms of intervention. By adopting a metaphorical approach, we conceptually explore how intervention provided by a social inclusion community center stimulates recipients to re-ignite their desire for self-improvement. This is achieved through an analogy made, comparing a Formula 1 motor racing team servicing a car during a pit-stop and a person (recipient) in need of food visiting a food bank to collect a food parcel. Based on a conceptual analysis, we propose a framework outlining the interactional process involving the social inclusion community center staff and a recipient, whereby the recipient becomes, through empowerment, an external operant actor and resource integrator for the social inclusion community center. This is achieved through a circular value co-creation process. Through the circular motion of the value co-creation, an external operant actor regains self-confidence due to gaining a sense of belonging and feeling inspired to contribute to the community they are associated with.

The “County-to-City Upgrading” policy represents a typical tool for central and local governments to promote the urbanization process through administrative empowerment. Do local governments’ policies promote innovation-driven high-quality and sustainable development? Under the context of the high-quality development of China’s economy, this paper examines the quantitative impact of the local governments’ “County-to-City Upgrading” policy on enterprises’ innovation. Using a staggered-DID model and the data from the Chinese Patent Database and the Industrial Enterprise Database from 2000 to 2013, the baseline results indicate that the policy not only increases the quantity of innovation but also improves the quality of innovation. The key findings of the research are the following: (1) The policy primarily promotes innovation activities among local enterprises through the cost reduction effect and resource accumulation effect. (2) The policy has a more significant impact on boosting innovation in the eastern regions as well as areas with stronger intellectual property protection. (3) The policy not only can advance technological and practical innovation but can also help enterprises overcome the problem of technological containment. (4) The policy has a prominent impact on green and low-carbon patents, which implies that it has become a significant drive pushing forward local green and sustainable development. Full article

This paper introduces a groundbreaking approach to demand response management, aiming to empower consumers through innovative strategies. The key contribution is the concept of “acquiring flexibility rights”, wherein consumers engage with power aggregators to curtail energy usage during peak-load periods, receiving incentives in return. A flexibility right coefficient is introduced, allowing consumers to tailor their participation in demand response programs, ensuring their well-being. Additionally, a lighting intensity control system is developed to enhance residential lighting network efficiency. The study demonstrates that high-energy consumers, adopting a satisfaction factor of 10, can achieve over 61% in electricity cost savings by combining the lighting control system and active participation in demand response programs. This not only reduces expenses but also generates income through the sale of flexibility rights. Conversely, low-energy consumers can fully offset their expenses and accumulate over USD 33 in earnings through the installation of solar panels. This paper formulates an optimization problem considering flexibility rights, lighting control, and time-of-use tariff rates. An algorithm is proposed for a distributed solution, and a sensitivity analysis is conducted for evaluation. The proposed method showcases significant benefits, including cost savings and income generation for consumers, while contributing to grid stability and reduced blackout occurrences. Real data from a residential district in Tehran validates the method’s effectiveness. This study concludes that this approach holds promise for demand response management in smart grids, emphasizing the importance of consumer empowerment and sustainable energy practices. Full article

Incorrect postural habits developed already at an early age are predictors of low back pain and functional limitations in adult life. Postural education programs (PEPs) are activities developed in Physical Education classes with the aim of promoting healthy habits. One tool used by PEPs is comics. The objective of this study was to develop comics and apply them as a teaching tool in PEPs for students aged seven to ten years. The procedures were based on individual empowerment principles, including creation activities, reading, painting, crosswords, and discussion of comics. The activities strengthened the students’ interactions, gaining new knowledge that required cognitive and expressive resources to interpret, associate, and conceptualize themes of correct body posture. During six weeks of intervention, knowledge about body posture, anatomy, and health promotion exercises increased significantly in relation to the beginning of activities. The comic book proved to be an effective, attractive, and low-cost didactic resource. Full article

Background: Complementary and alternative medicine (CAM) is widely used for multiple reasons such as treatment of diseases and their symptoms, empowerment, self-care, disease prevention, dissatisfaction, adverse effects or cost of conventional medicine, perception of compatibility with beliefs, and idiosyncrasy. This study investigated CAM use in patients with chronic kidney disease (CKD) undergoing peritoneal dialysis (PD). Methods: A cross-sectional survey study was conducted with 240 eligible patients with CKD in the PD program. By applying the I-CAM-Q-questionnaire, the frequency, level of satisfaction, and reasons for CAM use were explored, and the demographic and clinical data of users and non-users were analyzed. Data analysis included descriptive analysis, Student’s t-test, Mann-Whitney U, chi-square, and Fisher tests. Results: The main types of CAM used were herbal medicine, and chamomile was the most commonly used. To improve the state of well-being was the main reason for use, the attributable benefit of CAM was high, and only a low percentage of users reported side effects. Only 31.8% of the users informed their physicians. Conclusion: The use of CAM is popular among renal patients, and physicians are not adequately informed; in particular, the CAM type ingested represents a risk for drug interactions and toxicity.

Approximately 160 million children work as child laborers globally, 39% of whom are female. Ghana is one of the countries with the highest rates of child labor. Child labor has serious health, mental health, and educational consequences, and those who migrate independently for child labor are even at higher risk. Yet, evidence-based efforts to prevent unaccompanied child migration are limited. In this study, we examined the acceptability of a family-level intervention, called ANZANSI (resilience in local language) combining two evidence-based interventions, a family economic empowerment intervention and a multiple family group family strengthening intervention, to reduce the risk factors associated with the independent migration of adolescent girls from the Northern region to big cities in Ghana. We conducted semi-structured interviews separately with 20 adolescent girls and their caregivers who participated in ANZANSI. Interviews were conducted in the local language and transcribed and translated verbatim. Informed by the theoretical framework of acceptability, the data were analyzed using thematic analysis. The results showed high intervention acceptability among both adolescent girls and their caregivers, including low burden, positive affective attitude, high perceived effectiveness, low opportunity costs, and high self-efficacy. The study findings underline the high need for such interventions in low-resource contexts in Ghana and provide the foundation for testing this intervention in a larger randomized trial. Full article

Based on the digital transformation practice of Chinese manufacturing enterprises, this paper sorts out the intrinsic mechanism of digital transformation affecting the performance of manufacturing enterprises systematically, based on the perspective of digital investment, and empirically tests the theoretical hypothesis using an unbalanced panel of China’s A-share listed manufacturing companies in Shanghai and Shenzhen from 2007 to 2020. The findings show that digital transformation enhances manufacturing firm performance significantly, and the conclusions still hold after using dynamic panel models, the instrumental variables approach, and a series of robustness tests; further analysis reveals that this effect is more significant in state-owned enterprises and manufacturing enterprises in regions with a higher degree of marketization. The results of the mediating effect model show that low-cost empowerment and innovation empowerment are important channels to improve the performance of manufacturing enterprises. Accordingly, this paper argues that accelerating the deep integration of digital technology and enterprise development is the key to achieving high-quality development and improving enterprise performance in the context of an uncertain business environment.

The GLOBE Program’s GLOBE Observer Mosquito Habitat Mapper is a no-cost citizen scientist data collection tool compatible with Android and iOS devices. Available in 14 languages and 126 countries, it supports mosquito vector surveillance, mitigation, and education by interested individuals and as part of participatory community surveillance programs. For low-resource communities where mosquito control services are inadequate, the Mosquito Habitat Mapper supports local health action, empowerment, and environmental justice. The tangible benefits to human health supported by the Mosquito Habitat Mapper have encouraged its wide adoption, with more than 32,000 observations submitted from 84 countries. The Mosquito Habitat Mapper surveillance and data collection tool is complemented by an open database, a map visualization interface, data processing and analysis tools, and a supporting education and outreach campaign. The mobile app tool and associated research and education assets can be rapidly deployed in the event of a pandemic or local disease outbreak, contributing to global readiness and resilience in the face of mosquito-borne disease. Here, we describe the app, the Mosquito Habitat Mapper information system, examples of Mosquito Habitat Mapper deployment in scientific research, and the outreach campaign that supports volunteer training and STEM education of students worldwide.

Perinatal depression is highly prevalent in low- and middle-income countries (LMICs) and is associated with adverse maternal and child health consequences. Task-shared psychological and psychosocial interventions for perinatal depression have demonstrated clinical and cost-effectiveness when delivered on a large scale. However, task-sharing approaches, especially in LMICs, require an effective mechanism, whereby clients who are not likely to benefit from such interventions are identified from the outset so that they can benefit from higher intensity treatments. Such a stratified approach can ensure that limited resources are utilized appropriately and effectively. The use of standardized and easy-to-implement algorithmic devices (e.g., nomograms) could help with such targeted dissemination of interventions. The present investigation posits a prognostic model and a nomogram to predict the prognosis of perinatal depression among women in rural Pakistan. The nomogram was developed to deliver stratified model of care in primary care settings by identifying those women who respond well to a non-specialist delivered intervention and those requiring specialist care. This secondary analysis utilized data from 903 pregnant women with depression who participated in a cluster randomized, controlled trial that tested the effectiveness of the Thinking Healthy Program in rural Rawalpindi, Pakistan. The participants were recruited from 40 union councils in two sub-districts of Rawalpindi and randomly assigned to intervention and enhanced usual care. Sixteen sessions of the THP intervention were delivered by trained community health workers to women with depression over pregnancy and the postnatal period. A trained assessment team used the Structured Clinical Interview for DSM-IV current major depressive episode module to diagnose major depressive disorder at baseline and post-intervention. The intervention received by the participants emerged as the most significant predictor in the prognostic model. Among clinical factors, baseline severity of core-emotional symptoms emerged as an essential predictor, followed by atypical symptoms and insomnia. Higher severity of these symptoms was associated with a poorer prognosis. Other important predictors of a favorable prognosis included support from one’s mother or mother-in-law, financial empowerment, higher socioeconomic class, and living in a joint family system. This prognostic model yielded acceptable discrimination (c-statistic = 0.75) and calibration to aid in personalized delivery of the intervention. Full article

PM2.5 is an air contaminant that has been widely associated with adverse respiratory and cardiovascular health, leading to increased hospital admissions and mortality. Following concerns reported by workers at an industrial facility located in Santa Ana, California, workers and community leaders collaborated with experts in the development of an air monitoring pilot study to measure PM2.5 concentrations to which employees and local residents are exposed during factory operating hours. To detect PM2.5, participants wore government-validated AtmoTube Pro personal air monitoring devices during three separate workdays (5 AM–1:30 PM) in August 2021. Results demonstrated a mean PM2.5 level inside the facility of 112.3 µg/m3, nearly seven-times greater than outdoors (17.3 µg/m3). Of the eight workers who wore personal indoor sampling devices, five showed measurements over 100 μg/m3. Welding-related activity inside the facility resulted in the greatest PM2.5 concentrations. This study demonstrates the utility of using low-cost air quality sensors combined with employee knowledge and participation for the investigation of workplace air pollution exposure as well as facilitation of greater health-related awareness, education, and empowerment among workers and community members. Results also underscore the need for basic measures of indoor air pollution control paired with ongoing air monitoring within the Santa Ana facility, and the importance of future air monitoring studies aimed at industrial facilities.

PM2.5 is an air pollutant that is widely associated with adverse health effects, and which tends to be disproportionately located near low-income communities and communities of color. We applied a community-engaged research approach to assess the distribution of PM2.5 concentrations in the context of community concerns and urban features within and around the city of Santa Ana, CA. Approximately 183 h of one-minute average PM2.5 measurements, along with high-resolution geographic coordinate measurements, were collected by volunteer community participants using roughly two dozen low-cost AtmoTube Pro air pollution sensors paired with real-time GPS tracking devices. PM2.5 varied by region, time of day, and month. In general, concentrations were higher near the city’s industrial corridor, which is an area of concern to local community members. While the freeway systems were shown to correlate with some degree of elevated air pollution, two of four sampling days demonstrated little to no visible association with freeway traffic. Concentrations tended to be higher within socioeconomically disadvantaged communities compared to other areas. This pilot study demonstrates the utility of using low-cost air pollution sensors for the application of community-engaged study designs that leverage community knowledge, enable high-density air monitoring, and facilitate greater health-related awareness, education, and empowerment among communities. The mobile air-monitoring approach used in this study, and its application to characterize the ambient air quality within a defined geographic region, is in contrast to other community-engaged studies, which employ fixed-site monitoring and/or focus on personal exposure. The findings from this study underscore the existence of environmental health inequities that persist in urban areas today, which can help to inform policy decisions related to health equity, future urban planning, and community access to resources.

In Colombia, most commercial drying processes are frequently performed through the burning of wood and fossil fuels with high costs and environmental damage. Nevertheless, solar drying is a technique that could also be used to reduce many of the problems present in traditional drying techniques. Finding low-cost technology to install a solar dryer in a vulnerable community of women is an appropriate alternative; the transfer of knowledge on this technique could lead to greater empowerment of women and prevent gender inequality. This study evaluated the color and water activity of the mango (Mangifera indica L.) after a drying process in a greenhouse dryer. Furthermore, this study showed the relevance of implementing this technique in a community of women affected by the military conflict in Colombia. Results showed that a solar dryer achieved drying times of around 23–26 h, reaching water activity values below the 0.5 threshold which, according to international standards, has been considered as a food safety value. In addition, the color of the dry mango is slightly affected through this drying technique, providing a more acceptable consumer product. The application of the solar dryer has proven to be an easy-to-use and environmentally friendly method. On the other hand, it is also an opportunity to improve, with a low-cost investment, the living conditions of vulnerable communities. Full article
