A Study of Genderlization and Critical Thinking in Buddhism
No full textThis study, which explores the relevance of critical thinking in religious literature on gender issues and the relevance of critical thinking in contemporary society, discovers the importance of critical thinking in religious teachings by providing space for open dialogues on religious ideas based on multifaceted social experiences. The results, and discussion of the results are based on thematic data collection and correlation analysis. Michael Thomaszewski says that critical thinking among learning skills consists of eight steps. Almost all of the Buddha's sermons are directed to be followed equally by both men and women. The study reveals that according to the Tripitaka, the Buddha's teachings treated equally in the granting of positions and the establishment of lay societies. The protection of gender equality in both domestic and social affairs is evident from the Sigalovada Sutta, the Dhithu Sutta, the Kundala Kesatheri Apadana and the Theratheri Gatha. Anguttara Nikaya 111 asserts that not only the father, but also the mother is the primary teacher of the children. Both father and mother are valued in as persons with the four types of Brahman qualities in Buddhism. The Mangala Sutta states that one who respects one's parents will prosper, while the Parabhava Sutta states that one who disrespects them will perish. According to the Tripitaka, positive comments on gender equality have been made in the teachings of Buddhism. In various aspects of society, men and women have been given equal rights, respect and recognition. Buddhism has looked critically at society and has shown the way towards the improvement by identifying the lessons and teachings of and in life. It can be critically concluded that Buddhist teachings have granted life and Dhamma to all who live, without violating human rights in order to preserve gender equality
Production of High-Energy-Density Biomass Material Utilizing Bagasse and Waste Oil Derived from the Service Center Operations
Get PDFBagasse is produced through the milling process of cane sugar manufacturing. These fibrous residue products are used for energy production. Waste crankcase oil (WCO) is a significant waste of a vehicle service center. This waste is generated through the motor engine oil changing procedure. Already, this waste product is polluting the environment. Densification is a promising technology for producing renewable fuels by compressing and reducing biomass volume, which is crucial for storing, handling, and transporting biomass. This study focuses on the production of high-energy- density briquettes utilizing sugarcane bagasse and WCO, with briquettes produced in various ratios ranging from 1:3 to 1:8 bagasse to WCO. The manual hydraulic press briquette machine is used for the production of briquettes. The physical properties of the briquettes are analyzed using calorific value (CV) and compressive strength. These physical properties are measured using an automatic calorimeter and a universal testing machine. FTIR was used to determine the chemical composition of the briquettes. The average CV of dry bagasse is approximately 21000 kJ/kg. The 1:8 briquettes observed the highest CV at 41141 kJ/kg, while the 1:3 ratio sample displayed the lowest at 26465 kJ/kg. The standard deviation of 7338 for the briquetted CV is significant. The findings show that an increased CV positively correlates with the amount of WCO. Compressive strength values are 6 MPa (1:3) and 6.1 MPa (1:8) ratio. The standard deviation of strength was 0.05. Based on the standard deviation, adding WCO did not significantly enhance the compressive strength of the briquettes. Chemical compositions are obtained by FTIR analysis, which shows that the 1:3 ratio has a phenolic, amide, and C-O component compared to the 1:8 sample. The 1:3 ratio is less harmful to the environment; however, the 1:8 ratio is useful to obtain a higher CV. Considering these findings, industries can develop high-energy-density briquettes to enhance energy efficiency and reduce environmental impact
Quantitative Estimation of Residual Stresses in Quenched Steel through Ultrasonic Parameters
Get PDFGenerally, residual stresses are present in the metal specimens after manufacturing and heat treatment processes. Quenching is a heat treatment process that forms residual stress in metals. Two testing methods are used to find residual stresses in the industry, which are Destructive and Non-Destructive. This research is focused on estimating residual stresses in quenched AISI 1045 Medium carbon steel using the Ultrasonic testing method as a non-destructive method. Water, Saltwater, and oil were used as three different quenching media to perform the quenching process. Ultrasound attenuation was used to measure the residual stresses in quenched steel, considering the difference in the attenuation coefficient before and after quenching. 12 mm thick AISI 1045 type steel sample was used to give the tensile stress, and the ultrasonic attenuation coefficient difference in stressed and zero-stressed conditions was measured. The obtained data were used to correlate the variation of stresses with the attenuation coefficient difference. Using this correlation and attenuation coefficient difference before and after quenching, we can estimate the residual stress of quenched steel samples. ABAQUS modeling software was used to simulate residual stresses. The Von Mises stress criterion was considered to be the simulation residual stress result. Those experimental and simulation values were compared for an identical correlation for residual stresses. The specimen's Centre Plane Von Mises stress criteria were considered to obtain the simulation stress values for comparison as maximum residual stresses occur in the Centre plane of the specimen. According to the experimental and simulation residual stress values, there is a Similarity between those values. Therefore, this methodology can be used to measure the internal residual stresses in quenched steel samples

Editorial Note
Get PDFThe Editorial Board of the Asian Journal of Marketing Management (AJMM), affiliated with the Department of Marketing Management, Faculty of Management Studies and Commerce, University of Sri Jayewardenepura, Sri Lanka, is pleased to present Volume 4, Issue 1 of the journal. This issue reflects the journal’s ongoing commitment to fostering scholarly excellence and addressing the evolving challenges in marketing, consumer behaviour, and digital transformation through theoretically grounded research and empirical insights.
This issue features seven research articles that explore a diverse range of topics, including consumer decision-making, omnichannel integration, digital marketing, social media marketing, sustainability in business transformation, and experiential branding. Collectively, these contributions enhance the understanding of contemporary marketing challenges while providing practical implications for scholars and industry practitioners.
The first article investigates the impact of user-generated content (UGC) on purchase intention among young Sri Lankan consumers in the clothing sector, underpinned by the Uses and Gratifications Theory (UGT). The study finds that different forms of UGC, such as content gratification, social relation gratification, and self-presentation, significantly influence consumer decisions, reinforcing the idea that brands must foster authentic digital engagement to maintain relevance. Future research could extend this framework by incorporating algorithm-driven content personalization and examining how AI-generated recommendations affect trust in UGC.
The second study examines the role of omnichannel integration in fostering positive word-of-mouth (WOM) among supermarket consumers, drawing from Service-Dominant Logic and Consumer Engagement Theory. The study demonstrates that relational integration, transactional coherence, and consistent informational presence enhance consumer advocacy. Given the rapid adoption of AI-driven chatbots and predictive analytics in retail, future studies could explore how automation moderates consumer perceptions of omnichannel service quality.
The third paper examines the impact of immersion on the travel behavioural intentions of Gen Z tourists, highlighting the mediating role of happiness. Grounded in Experience Economy Theory and Positive Psychology, the study emphasizes the importance of deep emotional engagement in wildlife tourism experiences. The findings stress the need for immersive tourism providers to create experiences that promote happiness-driven behavioural intentions. Future directions may include neuroscientific methods for analysing immersive travel experiences, as well as applications in virtual reality (VR) tourism.
The fourth article investigates intelligent transformation in Sri Lankan SMEs, with corporate social responsibility (CSR) as a moderating factor. It positions itself within the Innovation Diffusion Theory. The study finds that external factors such as technological readiness and regulatory support play a more significant role than internal firm characteristics in driving transformation. The discussion calls for policy interventions that encourage responsible AI adoption and sustainable digitalization. Future research may assess the interplay between digital transformation and social impact metrics.
The fifth study investigates experiential marketing strategies in Sri Lanka’s fast-food sector, examining the mediating role of experiential emotional value in revisit intention. Inspired by Experiential Marketing Framework, the study affirms that multi-sensory engagement, emotional resonance, and interactive customer experiences are pivotal in fostering repeat patronage. Given the evolving metaverse-based brand experiences, future research could explore augmented reality (AR) and virtual environments in experiential dining settings.
The sixth article investigates the role of celebrity endorsements in shaping consumer purchase intention in the Sri Lankan hair care industry, analyzing gender as a moderating factor. The findings align with the Source Credibility Model, confirming that trustworthiness, expertise, and attractiveness significantly influence consumer behavior. The study sparks further exploration into cultural variations in celebrity influence.
The final paper assesses the mediating role of perceived authenticity in the relationship between social media influencers (SMIs) and domestic tourist travel decisions in Sri Lanka. Drawing from Source Credibility Theory and Electronic Word-of-Mouth (eWOM) Theory, the study demonstrates that authenticity perception significantly enhances influencer-driven travel choices. This research opens new avenues for examining the risks of deepfake influencers and AI-generated content in digital tourism marketing.
As the marketing discipline continues to evolve in response to technological advancements, shifting consumer expectations, and regulatory transformations, future research should emphasize interdisciplinary approaches that integrate data science, behavioral psychology, and ethical marketing practices. Scholars and practitioners must consider the ethical implications of AI in marketing, the role of digital privacy in consumer trust, and the sustainability of immersive brand experiences.
We extend our deepest gratitude to the authors for their rigorous contributions, as well as to our esteemed reviewers for their invaluable insights, which have strengthened the quality of these publications. Our appreciation also goes to the language editors and the editorial team for their unwavering commitment to ensuring a seamless publication process. We hope this issue inspires further academic exploration and serves as a valuable resource for scholars and marketing practitioners worldwide
Development of Sustainable and Cost-effective Housing Designs for low-income communities in Sri Lanka; An Analysis of Materials and Construction Costs
Get PDFAccess to adequate housing is a fundamental human need and essential for individual and community well-being, much like food and water. Global housing developments, however, have made serious problems with the economy, society, and environment worse. Since sustainable housing can address these issues, it has become a major concern for governments, academic institutions, and business leaders. To succeed, sustainable housing must be technically feasible, socially acceptable, environmentally responsible, and economically viable. This study focuses on developing sustainable and cost-effective housing designs that focus on the specific needs of low-income communities in Sri Lanka. The approach begins with a comprehensive review of previous literature to identify key principles of sustainable construction. Based on these findings, the study proposes a housing design that integrates environmentally friendly materials for the foundation, flooring, walls, and roof. Multiple design scenarios will be evaluated based on the existing studies, and the associated costs calculated to determine the most viable and cost-effective option. The results of the study introduced sustainable and cost-effective building designs intergerning cost effective while environment-friendly materials for the foundation, external and internal walls, floor and roof to utilized. The estimated total cost of the most sustainable and cost-effective housing design across all the scenarios found that its around Rs 417,610. The outcomes of this research will offer valuable insights and guide recommendations for launching low-income housing projects. These solutions aim to address the housing crisis by promoting affordable and sustainable living environments within vulnerable communities in Sri Lanka
Understanding Investor Attitudes and Green Investment Behaviour – Evidence from Sri Lankan Green Investors
Get PDFGreen investment is now a buzzword that is strongly associated with sustainable development, yet investor engagement in green investment is seen as relatively poor, particularly in developing countries such as Sri Lanka. While there is burgeoning research on green consumerism and its antecedents, there appears to be little research on understanding green investment behaviour and its drivers. The present study thus investigates investor attitudes and green investment behaviour by drawing on green consumerism related antecedents by focusing on four key dimensions of investor attitudes: environmental consciousness, environmental responsibility, health consciousness, and social influence. The study collected quantitative data through a structured questionnaire from 399 current and prospective green investors across Sri Lanka. Findings revealed a strong positive correlation between these attitudinal drivers and the willingness to invest in green projects. Social influence emerged as the most significant variable, suggesting a herd mentality as well as social pressure with regard to green investments. Moreover, a gender-based difference was also observed, with male investors exhibiting a greater inclination toward green investments, often driven by potential financial benefits rather than purely environmental concerns. The findings also corroborate with ongoing global challenges related to green investments, such as insufficient returns, lack of risk mitigation tools, and weak market participation. Such findings thus underscore the need for innovative policy solutions such as green credit guarantees, community trust funds, and expanded roles for financial institutions to improve investor confidence. This research adds originality by examining individual investor behaviour in a developing market context, offering valuable insights for financial institutions and policymakers aiming to foster green investment through targeted strategies
Self-Management, Personal Management, Individual Management, and Personnel Management: A Simplified Introduction and Differentiation
Get PDFThis theoretical and foundational paper explores four interrelated yet distinct concepts, i.e., Self-Management (SM), Personal Management (PM), Individual Management (IM), and Personnel Management (PMgt) which are highly relevant to the field of Human Resource Management (HRM) but are often used interchangeably. Despite their significance, clear distinctions and well-defined meanings for each term remain underdeveloped, particularly within local academic and practical contexts. This paper aims to address this gap. Nominal definitions were developed for all four terms, establishing their potential as independent constructs. Using eight conceptual bases, the terms were carefully differentiated with a high degree of definitional precision and conceptual clarity. The resulting framework prevents confusion in teaching and practice, supports the design of HR policies and personal development programs, and reinforces both internal discipline (through self-regulation) and external managerial support. It is believed that this paper offers an original contribution to Sri Lankan HRM literature and will stimulate local academic discourse and teaching applications.

In-vitro Antioxidant, Sun Protection, Anti-inflammatory and Antibacterial Properties of F. leucopyrus, O. octandra and H. speciosa
Get PDFRich biodiversity and strong ethnopharmacological traditional knowledge in Sri Lanka provide an opportunity to utilize highly potential medicinal plant resources for sustainable products extending from pharmacological, food/beverages to cosmetic innovation. Flueggea leucopyrus, Osbeckia octandra, and Hellenia speciosa have been a research focus due to their medicinal benefits according to ethnopharmacology. The current study investigates the beneficial bioactivities of F. leucopyrus, O. octandra, and H. speciosa in terms of their antioxidant, in-vitro sun protection, and anti-inflammatory capacities, followed by antimicrobial activity in a range of extractions. The plant leaf water, glycerine, and ethanol extracts were subjected to antioxidant assays: Total Phenol Content (TPC) as Gallic Acid Equivalent (GAE), Total Flavonoid Content (TFC) as Rutin Equivalent (RE), and DPPH free-radical scavenging percentage (DPPHfrs%) followed by in-vitro Sun Protection Factor (SPF) and egg-albumin anti-coagulation effect for in-vitro Anti-Inflammatory percentage (AI%). The antibacterial activities against Staphylococcus aureus and Pseudomonas aureoginosa strains were tested for water and ethanol extracts of the medicinal plants using disk diffusion and Resazurin assays. The TPC, TFC, and DPPHfrs% of F. leucopyrus ranged from 0.154 g/L to 0.852 g/L, 0.009 g/L to 0.455 g/L and 84.349% to 91.713%, while O. octandra ranging from 0.131 g/L to 1.113 g/L, 0.008 g/L to 0.160 g/L and 79.607% to 92.387% respectively. H. speciosa showed TPC, TFC, and DPPHfrs% ranging from 0.010 g/L to 3.024 g/L, 0.002 g/L to 0.410 g/L and 26.388% to 57.716% respectively. The SPF of F. leucopyrus, O. octandra, and H. speciosa, ranged from 33 to 40, 19 to 40, and 6 to 34 respectively. AI% of F. leucopyrus, O. octandra, and H. speciosa followed 9.037% and 11.940%, 8.418% and 11.852%, 12.515% and 12.000% respectively (water and ethanol extracts respectively). Crude ethanolic leaf extracts of F. leucopyrus and H. speciosa in a higher concentration of 50 mg/mL showed antibacterial activity against S. aureus. Thus, the current plant selection of F. leucopyrus, O. octandra, and H. speciosa can be considered as high potential resources for sustainable products with consideration on the extraction protocols as they can brighten, heal, and hydrate skin and body.
