by Ma. Janice J. Gumasing
COVID 2025, 5(3), 38; https://doi.org/10.3390/covid5030038 (registering DOI) - 8 Mar 2025

This study examines the factors influencing the behavioral intention and compliance behavior of Transportation Network Vehicle Service (TNVS) drivers during the COVID-19 pandemic. Grounded in the Theory of Planned Behavior (TPB) and the Health Belief Model (HBM), the study integrates psychological, environmental, and organizational factors to explain TNVS drivers’ adherence to safety protocols. Data were collected from 342 TNVS drivers in the National Capital Region (NCR) and CALABARZON through a structured survey. Structural Equation Modeling (SEM) was employed to analyze the relationships among variables and assess the determinants of compliance behavior. The results indicate that attitude toward compliance (β = 0.453, p < 0.001), risk perception (β = 0.289, p = 0.001), availability of personal protective equipment (PPE) (β = 0.341, p < 0.001), passenger compliance (β = 0.293, p = 0.002), company policies (β = 0.336, p = 0.001), and organizational support systems (β = 0.433, p < 0.001) significantly influence behavioral intention. In turn, behavioral intention strongly predicts compliance behavior (β = 0.643, p < 0.001), confirming its mediating role in linking influencing factors to actual adherence. However, stress and fatigue (β = 0.131, p = 0.211), ride conditions (β = 0.198, p = 0.241), and communication and training (β = 0.211, p = 0.058) showed non-significant relationships, suggesting that their direct effects on behavioral intention are limited. The model explains 69.1% of the variance in compliance behavior, demonstrating its robustness. These findings highlight the importance of fostering positive attitudes, ensuring adequate resource availability, and reinforcing organizational support to improve TNVS drivers’ compliance with safety measures. Practical recommendations include implementing educational campaigns, ensuring PPE access, strengthening company policies, and promoting passenger adherence to safety protocols. The study contributes to the broader understanding of health behavior in the ride-hailing sector, offering actionable insights for policymakers, ride-hailing platforms, and public health authorities. Future research should explore additional contextual factors, gender-based differences, and regional variations, as well as assess long-term compliance behaviors beyond the pandemic context.

Research Objective: This study aims to examine the impact of religious-based family management (RBFM) on absolute poverty through two main factors: short-term vision and uncontrolled consumption among low-income families. Research Methods and Approach: This study analyzed 172 respondents (low-income families) using a quantitative approach with the Amos Structural Equation Modeling (SEM) method. A questionnaire was the main instrument in this study of six regions in South Sulawesi. Findings and Research Novelty: The findings reveal that, as an “agent of change”, RBFM has a significant negative effect on short-term vision, uncontrolled consumption, and absolute poverty. These results underscore the role of integrating religious values in family management to curb excessive consumption behavior and strengthen long-term financial planning, thereby potentially breaking the cycle of poverty. The novelty of this research lies in employing Human Capital Theory (HCT) and the Theory of Planned Behavior (TPB) to elucidate the role of religion in the economic dynamics of family life. Research Implications: This study provides important implications for poverty alleviation policies, particularly in developing value-based programs that integrate religious principles with financial literacy. Such interventions are expected to enhance financial management practices among low-income families and foster their economic sustainability. Full article

The shift to sustainable energy requires a thorough understanding of the elements affecting policy adoption, especially regarding political and economic dynamics. Current approaches, such as the technology acceptance model (TAM), theory of planned behavior (TPB), and unified theory of acceptance and use of technology (UTAUT), mainly emphasize individual behavioral aspects, often neglecting macro-level implications. This research uses the hybrid model for energy policy adoption (HMEPA) to bridge this gap, including economic and political factors with behavioral theories to evaluate energy policy acceptability. We propose that social impact, attitudes toward the policy, and financial and political considerations substantially affect stakeholders’ acceptance intentions. We gathered 421 valid answers from people in Taiwan using a questionnaire survey and analyzed the data using structural equation modeling (SEM). The findings demonstrate that whereas effort expectation and enabling circumstances have little impact, social influence and attitude are the most significant determinants of policy adoption intention. Moreover, political variables influence attitudes and social dynamics, while economic policy impacts performance expectations, perceived behavioral control, and enabling circumstances. These results underscore the need to synchronize policy plans with political and economic realities. Policymakers may use these findings to formulate stakeholder-oriented policies that promote sustainable energy transitions. Full article

Effective tunnel construction and demolition (C&D) waste management is a critical issue in the context of sustainable development, and C&D waste management measures guided by 3R principles (Reduce, Reuse, and Recycle) comply with the circular economy. In this study, an extended theory of planned behavior model based on the existing literature was proposed to identify the drivers of tunnel construction managers’ intention to implement effective waste management measures; then, the respondents were classified into four groups according to personality traits to explore the effects of personality profile on the heterogeneity in relationships between psychological drivers and C&D waste management intention and behaviors. The results show that all TPB constructs, policies, and environmental concern are significant predictors of managers’ intention to manage C&D waste properly. Then, considerable variance in the driving effects of various psychological drivers across different groups is witnessed. For the positive and temperate participants, subjective norms and policies are the most effective driving factors. However, PBC and environmental concern show a stronger relationship with the conservative and introverted participants’ intentions to adopt effective waste management measures. The findings are beneficial to developing corresponding management measures to promote effective C&D waste management. Full article

S. pupariae is a newly discovered species of parasitoid wasps. Research into its development, behavioral genetics, and molecular mechanisms provides valuable insights for improving integrated pest management strategies. Quantitative real-time PCR (qRT-PCR) is the most commonly used method for analyzing gene expression. This method requires the identification of stable reference genes to accurately evaluate transcriptional level variations. In this study, eight candidate reference genes (TUB, TBP, RPS18, GAPDH, 18S rRNA, RPL32, Actin, and EF1-α) were identified and evaluated for their suitability as reference genes. Gene expression levels across different developmental stages were analyzed using three software tools, GeNorm, NormFinder, and BestKeeper, and the online tool RefFinder. The overall ranking of reference gene stability was as follows: RPS18 > 18S rRNA > RPL32 > GAPDH > Actin > TUB > TPB > EF1-α. Ultimately, RPS18 was determined to be the most stable reference gene.

A covalent organic framework TPB-DMTP was physically coated onto the gully-like surface of stainless-steel fiber. The fabricated TPB-DMTP-coated stainless-steel fiber was used to extract five phthalic acid esters (PAEs) prior to the GC-FID separation and determination in bottled tea beverages. The developed SPME-GC-FID method gave limits of detection (S/N = 3) from 0.04 µg·L−1 (DBP) to 0.44 µg·L−1 (BBP), with the enrichment factors from 268 (DEHP) to 2657 (DPP). The relative standard deviations (RSDs) of the built method for inter-day and fiber-to-fiber were 4.1–11.8% and 2.3–9.9%, respectively. The prepared TPB-DMTP-coated stainless-steel fibers could stand at least 180 cycles without a significant loss of extraction efficiency. The developed method was successfully applied for the determination of trace PAEs in different bottled tea beverages, with recoveries from 85.5% to 115%. Full article

Low-carbon tourism (LCT) has emerged as a pivotal approach to mitigate the environmental impact of tourism, particularly its contribution to greenhouse gas emissions. This study develops a structural equation model (SEM) to investigate the factors influencing decision-making in selecting low-carbon tourism destinations. The research integrates key variables including destination characteristics, marketing strategies, and tourist perceptions, grounded in the Theory of Planned Behavior (TPB) and consumer behavior theory. Data were collected from 405 tourists visiting Khaoyai National Park, one of Thailand’s most popular nature-based destinations, utilizing structured questionnaires and a robust sampling strategy. Findings reveal significant interrelationships among destination characteristics, marketing strategies, and tourists’ perceptions of LCT, which collectively shape decision-making processes. Enhanced perceptions of LCT are mediated by innovative marketing communications and sustainable destination features, emphasizing the role of eco-friendly practices in fostering responsible tourism. The study underscores the importance of aligning policy, business strategies, and tourist education to promote sustainable travel behaviors. These insights provide practical guidelines for stakeholders to advance low-carbon tourism initiatives while preserving the integrity of tourist experiences and environmental stewardship.

With the escalating environmental issues, the imperatives to mitigate greenhouse gas emissions and advance energy products through innovation, energy production, and consumption frequently result in environmental externalities. Conventional markets frequently struggle to address these external factors, resulting in market failures. Consumers are more aware of the environmental repercussions, regulatory mandates, and potential economic benefits of new energy vehicles (NEVs). Consequently, there has been a substantial surge in the demand for NEVs as alternatives to conventional vehicles. This study analyses the method by which innovative technology moves from the stage of purchase intention dissemination toward market adoption and explores strategies to expedite this process. Moreover, it examines how the intentions of customers to purchase ecologically friendly energy goods and their receptiveness to such products affect the expansion of the market. Further analysis indicates that the factors influencing consumers’ attitudes towards NEVs include the adoption of ecological innovation, awareness of environmental product knowledge, and perceived value of innovative, environmentally friendly energy products. The purpose of this study is to expand upon the existing literature on consumer demand, examining the influential factors that extend the Theory of Planned Behaviour (TPB) to enhance consumer intention through internal mechanisms. It explicitly focuses on these aspects, as well as perceived risk (PR) and perceived value (PV), to identify gaps in the literature and contribute to intentions to purchase NEVs in China. This study presents a thorough research framework for efficiently examining customer demand for comparable eco-friendly energy products. It investigates the potential influence of attitudes, subjective norms, perceived behavioural control, and environmental perceptions, specifically those concerning environmental knowledge and concerns. Moreover, personal factors such as attitude, normative beliefs, and perceived control beliefs were found to impact consumer attitudes towards NEVs. The key factor influencing purchasing intention was the attitude towards NEVs. Simultaneously, subjective norms did not have a direct effect on purchase intentions. However, social influence played a significant role in the decision-making process, with perceived behavioural control and subjective norms exerting considerable influence. Full article

This paper explores the intersection of tourism and environmental theories, highlighting how sustainability serves as a critical bridge between the two disciplines. Tourism theories such as Butler’s Tourism Area Life Cycle (TALC) and the Theory of Planned Behavior (TPB) provide insights into destination development and tourist behavior but often lack an ecological perspective. The environmental framework, including Ecological Modernization Theory (EMT) and Common-Pool Resource (CPR) Theory, emphasizes sustainable resource management and the interconnectedness of human activities and natural systems. This paper examines common concepts such as carrying capacity, sustainable development, and behavioral insights while also identifying tensions between economic growth and environmental preservation. Case studies from Costa Rica, Hawaii, and Thailand illustrate practical applications of these theories in real-world settings, revealing how tourism can be both a threat and a tool for conservation. My paper concludes that integrating environmental impact assessment (EIA) and community-based tourism (CBT) models into tourism planning can lead to better long-term resource management. It recommends the adoption of stricter regulations on tourism development in fragile ecosystems, the implementation of eco-certifications, and the promotion of locally governed tourism initiatives. These strategies will ensure the sustainability of both tourism activities and the ecosystems on which they depend. Full article

The high seismic vulnerability of unreinforced masonry buildings urgently calls for researchers to develop sustainable reinforcing methods and materials. This paper presents an innovative lime-based mortar reinforced with randomly oriented basalt fibers for the reinforcement of masonry heritage. The main aim of this study is to understand the effect of the content and the length of basalt fibers on the mortar’s mechanical behavior. As a cementitious material made mostly out of lime, the mortar is chemically compatible with the historical substrate and therefore suitable in cases of restoration works on architectural heritage. Moreover, the chopped basalt fibers are randomly oriented, and this characteristic makes the overall layer effective in all directions, as the state of stress induced by seismic action is directionally undetermined. The newly proposed reinforcement system is characterized by a twofold aspect related to sustainability: 30% of the aggregates composing the mortar mix design is a recycled result of the ruins of the 2009 L’Aquila earthquake, and the chopped fibers are made out of basalt, widely known for its environmentally supportable peculiarity. The study consists of testing samples characterized by two fiber lengths and six fiber contents, along with one set of plain mortar samples. Specimens measuring 160 mm × 40 mm × 40 mm are first tested in a three-point bending (TPB) configuration, aiming to determine the flexural strength and the post-peak capacity through the calculation of the fracture energy. Then, the two broken pieces resulting from the TPB tests, each measuring 80 mm × 40 mm × 40 mm, are tested in splitting and compression, respectively, aiming to compute the tensile and compressive strengths. Finally, to provide a trend for the mortar’s mechanical properties, a regression analysis is performed by fitting the experimental data with simple linear, polynomial, and exponential regression models. Results show that: (i) both fiber content and fiber length are responsible for a linear increase of the flexural strength and the fracture energy; (ii) for both short- and long-fiber mortar samples, the tensile strength and the compressive strength parabolically increase with the fiber content; (iii) the increase in fiber content and fiber length always generates a reduction in the conglomerate workability. The fiber content (FC) optimization with respect to the mechanical properties leads to a basalt FC equal to 1.2% for long-fiber samples and an FC equal to 1.9% for short-fiber ones. Full article

The rising amount of electronic waste (e-waste) presents serious threats to the environment and public health. Addressing this challenge necessitates a focus on improving the e-waste recycling rate, which is facilitated by consumers’ spontaneous participation. This paper explores the factors influencing young consumers’ e-waste recycling behavior (EWRB) from a developing country’s perspective. Though existing literature has addressed various factors affecting EWRB, the role of individuals’ pro-environmental goals (PEG) remains underexplored. This paper provides an integrated theoretical model that incorporates PEG alongside factors drawn from the Theory of Planned Behavior (TPB), Norm Activation Model (NAM), and Behavioral Reasoning Theory (BRT). Data were collected through a survey and analyzed using structural equation modeling. The results reveal that young consumers’ intentions toward EWRB are significantly influenced by economic benefits, perceived behavioral control, moral norms, and PEG, while economic benefits emerge as the most influential factor. However, the impact of attitude and subjective norm on intention was found to be insignificant. Results indicate that despite having positive intentions, young consumers were often deterred from recycling e-waste due to perceived risks, indicating a negative moderating effect of perceived risk on the intention–behavior relationship. Conversely, PEG positively moderates the impact of intention on EWRB, reducing the intention–behavior gap. This paper contributes to the literature by enhancing our understanding of how PEG interacts with other factors affecting EWRB. Practically, the findings offer valuable recommendations for policymakers and practitioners aiming to promote EWRB among young consumers, particularly in Bangladesh. Full article

This paper addresses a research gap by examining how two groups of individuals with different personality traits (more entrepreneurial personalities versus less entrepreneurial personalities) react to changes in entrepreneurial intention after attending an entrepreneurship course. A key aspect of this study lies in its application of MEMORE; this tool was crucial in determining whether changes in entrepreneurial intention were driven by changes in the factors of the Theory of Planned Behavior (TPB) in each group of individuals. The survey employed a pre-test–post-test questionnaire design distributed before and after a university-level entrepreneurship course. The results indicated that individuals with more entrepreneurial personalities (characterized by high openness, conscientiousness, and extraversion and low neuroticism and risk aversion) had higher levels of entrepreneurial intention, attitude, subjective norms, and perceived behavioral control compared to less entrepreneurial personalities. After the course, more entrepreneurial personalities reported higher entrepreneurial intentions and perceived behavioral control. MEMORE indicated that changes in perceived behavioral control affected the increase in entrepreneurial intentions. Less entrepreneurial personalities demonstrated a decline in entrepreneurial intention but a positive change in perceived behavioral control; this change did not affect the decline in entrepreneurial intentions. This study provides essential insights into an underexplored area, advancing knowledge in this field. Full article

The driving range and replenishment problem of electric vehicles have become the main contradictions that interfere with consumers’ purchasing decisions. To alleviate these problems, battery-swap technology has been introduced into the public view. Existing research rarely explores the factors that affect consumers’ decision of purchasing electric vehicles. This article introduces the Technology Acceptance Model (TAM), as well as the Theory of Planned Behavior (TPB) with its extensions and the perceived risk, to construct the structural equation model (SEM) based on TAM and TPB, and studies the influence mechanism of the purchase intention of electric vehicles with a battery-swap mode. A total of 530 valid questionnaires were collected from participants in Beijing, providing a representative sample for the study. The results show that attitude, technological development, perceived behavior control, environmental awareness, and subjective norm have significant positive influences on the purchase intention, and the influences increase in turn; perceived risk has a significant negative effect; subjective norms and environmental awareness have an indirect positive effect.

(1) Background: With the growing severity of global environmental issues and increasing consumer health consciousness, green consumption has become a prominent focus in both research and practice. However, studies on the mechanisms of health consciousness and environmental awareness influencing the purchase intentions of sports enthusiasts toward sustainable sports products remain relatively limited. This study investigates how health consciousness and environmental awareness impact the green consumption behavior of sports enthusiasts through psychological pathways, including attitude, subjective norm, and perceived behavioral control, aiming to reveal their underlying mechanisms. (2) Methods: Based on the extended Theory of Planned Behavior (TPB), this study developed a theoretical model incorporating health consciousness and environmental awareness. Data were collected via a questionnaire survey, yielding 407 valid responses. The sample was gender-balanced (52.8% male, 47.2% female), predominantly consisting of young individuals aged 26–35 (44.7%) and 18–25 (28.0%), with primary occupations being company employees/managers (46.2%) and students/teachers (25.3%). The collected data were analyzed using SPSS and AMOS software to systematically evaluate the research hypotheses and the model’s applicability. (3) Results: The model exhibited excellent fit indices, with a χ2/df value of 2.129, an RMSEA value of 0.053, an RMR value of 0.029, and GFI, CFI, NFI, and NNFI values all exceeding 0.90, indicating that the model structure adequately explained the relationships among latent variables. All research hypotheses were significantly supported (p < 0.01), demonstrating that health consciousness and environmental awareness not only directly influence purchase intentions but also exert significant indirect effects through attitude, subjective norm, and perceived behavioral control. (4) Conclusions: Health consciousness and environmental awareness are critical drivers of sports enthusiasts’ purchasing behavior for sustainable sports products. This study deepens the understanding of the mechanisms underlying green consumption behavior and offers practical implications for related businesses. Companies should enhance product healthiness and environmental friendliness while optimizing consumer psychological perceptions to increase purchase intentions. Full article

Background/Objectives: Primary caregivers of children play a significant role in developing their dietary behaviors. Guided by the Theory of Planned Behavior (TPB), this integrative review aimed to synthesize studies examining how personal and household characteristics, caregivers’ dietary beliefs, intentions, and feeding practices influence the eating behaviors of preschool-aged children (2–5 years). Methods: PubMed, CINAHL, and PsycINFO databases were searched for peer-reviewed articles published between January 2014 and September 2024. The expanded PRISMA 2020 checklist was used to guide the literature search and report the results. The Johns Hopkins Nursing Evidence-Based Practice (JHNEBP) was also used to evaluate the quality of the selected articles. Results: A total of 10 studies were included in the final analysis. The studies revealed that preschoolers’ eating behaviors were significantly influenced by personal characteristics (e.g., caregivers’ BMI, and weight perceptions) and household factors (e.g., food availability). Additionally, caregivers’ feeding practices, such as restriction, modeling, and permissiveness, played a pivotal role in shaping children’s eating habits. Although caregivers expressed intentions to provide a healthy diet, they often faced barriers, including conflicting work schedules, financial constraints, and logistical challenges, which impeded their ability to consistently promote healthy eating behaviors. Conclusions: Caregivers’ beliefs, intentions, and feeding practices are pivotal in shaping preschoolers’ eating behaviors. However, the limited available literature and the underexplored mechanisms linking these factors make it challenging to draw solid conclusions. Future research should address these gaps and consider integrating caregiver-focused factors into tailored interventions to promote healthier eating habits in preschool-aged children. This can aid healthcare professionals in designing culturally and contextually sensitive strategies for improving childhood nutrition. Full article
