This study analyzed participatory governance in Local Tourism Councils across Central Luzon, Philippines. Employing a mixed-methods research design, the study gathered data from respondents comprising tourism stakeholders through surveys, interviews, and document analysis to assess the current state of tourism governance in selected Local Government Units (LGUs). Findings revealed that local communities actively participate in tourism activities through inclusive decision-making processes facilitated by Local Tourism Councils. Regular stakeholder meetings and consultations ensure effective coordination, while digital platforms and local networks promote transparency and accessibility of tourism information. Evidence-based deliberations involving multiple stakeholders reflect high-quality governance practices, resulting in strong stakeholder satisfaction driven by community participation and visible economic benefits. Tourism performance indicators demonstrate exceptional results across key metrics. Tourist arrivals (M=3.93), economic contribution (M=3.96), tourist experience (M=3.95), and residents' perception (M=3.93) were all categorized as Very Good, while employment generation (M=3.78) and tourism infrastructure (M=3.62) also achieved Very Good ratings. Tourism sustainability (M=3.49) was rated Good, indicating opportunities for further enhancement. LGUs successfully implemented diverse tourism initiatives including surfing, heritage, eco, and event tourism, leveraging local assets and fostering community engagement. The study identifies areas for development, including digital infrastructure enhancement, improved accessibility for persons with disabilities, carrying capacity management, climate preparedness strengthening, and waste management system upgrades. Corresponding solutions are proposed: establishing digital corridors, implementing PWD-inclusive initiatives, developing visitor management systems, creating climate adaptation councils, and launching zero-waste programs. The research concludes that effective governance structures, legal frameworks, and community-centered approaches support sustainable tourism development in Central Luzon. Recommendations emphasize strengthening participatory mechanisms, enhancing infrastructure, expanding best practices, and addressing identified areas for improvement to ensure long-term tourism sustainability and maximizing economic, social, and cultural benefits for local communities.

Abstract: India frequently faces natural disasters, including floods, cyclones, and earthquakes, where timely and reliable reporting is crucial for public safety. AI-generated videos are increasingly employed in journalism to deliver rapid updates, visualize events, and aid in fact-checking. While AI improves reporting efficiency, it also poses risks of misinformation through deepfakes and manipulated visuals. This study explores the dual impact of AI-generated videos in Indian crisis journalism using surveys, expert interviews, and case analyses of events like the Kerala floods (2018) and Cyclone Fani (2019). Findings reveal that while AI videos are helpful, trust issues and regional-language detection challenges remain. Recommendations include ethical guidelines, journalist training, and public awareness campaigns.

The Self-Compacting Concrete (SCC) is that which gets compacted due to its self-weight and is deaerated (no entrapped air) almost completely while flowing in the form work. In recent times self-compacting concrete has been accepted as a quality product and are widely used. The addition of fly ash and silica fumes to concrete imparts superior mechanical properties to Self Compacting Concrete. The aim of this project work is to study the strength behavior of SCC partial replacement of cement with fly ash and silica fumes. Fly ash silica fume Self Compacting Concrete (FASF SCC) has been cast with volume fractions of 00%, 05%, 10% and 15% of silica fumes based on "Nan Su et.al" method and tested after 28 days of normal curing. This work also comprises the study of the effect of steel fibers on workability in fresh state and the compressive strength of cubes (150mmx150mmx150mm), split tensile strength of cylinders (diameter 150 mm and height 300mm), modulus of rupture of beams (100mmx100mmx500mm) in hardened state after 7,14, and 28 days of normal water curing. The results showed that the ultimate strength has increased marginally. The optimum volume fraction of silica fumes for better performance in terms of strength and ductility has been found to be 10%. Based on the results obtained from the investigations and after rational discussion, the conclusions have been developed on the fresh state properties of FASF SCC, hardened properties of FASF SCC, and the optimum dosage of silica fume.

Malpositioned dental implants present significant functional, esthetic, and biomechanical challenges, arising from inaccuracies in three-dimensional positioning related to spatial, angular, and rotational deviations. These errors may result from anatomical limitations, planning deficiencies, surgical inexperience, or inadequate use of digital guidance, leading to complications such as peri-implantitis, soft-tissue recession, prosthetic misfit, and compromised load distribution. This review summarizes the classification of implant malpositions and critically evaluates available corrective strategies, including prosthetic compensation, implantoplasty, ridge and soft-tissue augmentation, segmental osteotomy, and definitive explantation with re-implantation. Additionally, the role of digital workflows AI-enhanced diagnostics, CBCT-based planning, dynamic navigation, and 3D-printed guides--is highlighted for both prevention and correction. Treatment selection depends on the severity and clinical impact of the malposition, with multidisciplinary planning essential for predictable functional and esthetic outcomes. A comprehensive understanding of these corrective options supports safer, more precise, and patient-centered implant rehabilitation.

This work investigates the performance of Steel Fibre Reinforced Concrete (SFRC) prepared with M30 grade concrete incorporating different fibre volume fractions (0%, 0.5%, 1.0% and 1.5%). The primary aim of the investigation was to assess how the addition of steel fibres affects the workability and mechanical behaviour of concrete, including compressive, split tensile, and flexural strengths. The concrete mix design followed the guidelines of IS 10262:2019, and tests were conducted on specimens after 7, 14, and 28 days of curing.The inclusion of steel fibres led to notable improvement in tensile and flexural performance, whereas compressive strength showed only moderate enhancement. The maximum improvement in overall mechanical behaviour was observed at 1.0% fibre content. The results demonstrate that SFRC exhibits superior structural efficiency, toughness, and energy absorption capacity due to its enhanced post-cracking response, improved ductility, and effective crack-bridging mechanism. In comparison to conventional concrete, SFRC achieved substantially higher tensile and flexural strengths with only marginal gains in compressive strength. Therefore, the study confirms the suitability of SFRC for structural applications where improved toughness, ductility, and energy dissipation characteristics are required.

There is a growing awareness among people all over the world regarding the requirement of green marketing, environmental marketing, and ecological marketing, all of which share the same significance for the study sector. Green marketing is a marketing strategy that is made up of environmentally friendly practices. Despite the fact that environmental issues have an effect on almost every activity that consumer participate in their lives today, they still continue to engage in these many activities. For the Indian business discipline, the fast-moving consumer goods (FMCG) industry is a very large sector in the economy that has to learn more about being environmentally friendly. This is especially true from the perspective of the Indian business discipline. Given that the natural environment is growing more complicated as a consequence of environmental degradation and unethical commercial practices, consumers and business organisations are now becoming increasingly concerned about the natural environment. This is because of the fact that the natural environment is becoming more complicated. In an effort to address the "new" concerns that contemporary society has, businesses have begun to make modifications to the manner in which they conduct themselves. The fast-moving consumer goods (FMCG) industry is one of the growing businesses that is concerned about the issues that come with green marketing. Environmentally friendly components are being used as effective marketing strategies by the vast majority of marketing professionals nowadays. As a result of this, the objective of this study is to investigate the perspectives of consumers in the fast-moving consumer goods business about products that are favourable to the environment.

The rapid evolution of digital technologies has transformed the foundations of contemporary marketing, reshaping how firms create value, engage consumers, and compete in increasingly dynamic environments. Marketing in the Age of Digitalization: Critical Problems and Integrated Solution Pathways examines the multifaceted challenges posed by digital transformation and proposes holistic strategies to navigate these complexities. This article synthesizes current academic and industry perspectives to highlight four major problem domains: data proliferation and privacy concerns, algorithmic bias and ethical dilemmas in AI-driven decision-making, digital customer experience fragmentation, and the pressures of platform-dominated markets. First, the unprecedented volume of consumer data enables highly personalized marketing but simultaneously introduces significant privacy, security, and regulatory challenges. Conflicts between personalization and consumer autonomy, along with varying global data protection frameworks, create operational uncertainties for firms. Second, the rising reliance on artificial intelligence and machine learning generates new layers of opacity and potential bias. While AI enhances targeting accuracy and automation efficiency, it also risks reinforcing unfair practices or eroding trust when decision-making processes lack transparency. Addressing these issues requires governance models that balance performance with accountability. Third, digitalization has fragmented the customer journey across multiple touchpoints--including social media, mobile applications, e-commerce platforms, and emerging interfaces like voice assistants--making it increasingly difficult for firms to deliver coherent, seamless experiences. This fragmentation often results in inconsistent branding, message dilution, and weakened customer loyalty. Developing integrated omnichannel strategies supported by real-time analytics is essential to bridge these gaps. Fourth, the dominance of digital platforms such as search engines, social media networks, and online marketplaces introduces structural challenges, including heightened competition, dependency risks, and reduced control over consumer data. Firms must adopt platform-aware strategies and explore alternative digital ecosystems to mitigate these vulnerabilities. To address these interconnected issues, the article proposes an integrated solution framework built around four pillars: ethical data stewardship, human-centered AI governance, omnichannel experience orchestration, and platform diversification. Ethical data stewardship emphasizes transparent data practices, informed consent, and secure infrastructure. Human-centered AI governance promotes fairness, explainability, and the integration of human oversight in algorithmic systems. Omnichannel orchestration leverages unified data architectures and experience design principles to ensure consistency across touchpoints. Finally, platform diversification encourages firms to build collaborative ecosystems, strengthen owned digital assets, and reduce overreliance on dominant intermediaries. By synthesizing emerging evidence and offering actionable pathways, this study contributes to ongoing debates on how marketing can remain effective, responsible, and resilient in an era defined by digital transformation. The article provides scholars with a conceptual framework for future research and offers practitioners practical guidance for navigating the challenges and opportunities of digital-era marketing.

The present investigation describes the synthesis of a novel macrocyclic ligand obtained through the condensation of benzyl and oxalyldihydrazide in a methanolic medium under reflux conditions. The reaction yields a stable, crystalline macrocycle containing both nitrogen and oxygen donor centers capable of coordinating with transition metal ions. The ligand was subsequently allowed to react with divalent cobalt, nickel, and copper salts in the presence of chloride, nitrate, and acetate anions, resulting in a series of metal complexes of the general formula [M(C??H??N?O?)X?], where M = Co(II), Ni(II), Cu(II) and X = Cl?, NO??, or OAc?. Comprehensive analytical and physicochemical studies were carried out to confirm the composition and structural features of the synthesized ligand and its complexes. Elemental analysis and molecular weight determination verified the proposed stochiometry, while molar conductance measurements indicated their non-electrolytic or weakly electrolytic nature depending on the coordinating anion. The magnetic susceptibility data, together with electronic spectral transitions, provided valuable insight into the electronic environment of the metal ions and strongly suggested the formation of six-coordinate octahedral complexes. Spectroscopic investigations--including infrared, far-infrared, UV-Visible, and proton NMR studies--revealed significant shifts in characteristic vibrational and electronic bands, confirming the coordination of metal ions through azomethine nitrogen and carbonyl oxygen atoms of the macrocyclic framework. Infrared spectra displayed lowering of C=N and C=O stretching frequencies upon complexation, supporting metal-ligand bond formation, while far-IR spectra provided additional evidence through metal-nitrogen and metal-oxygen vibrational bands. The UV-Vis spectra exhibited characteristic d-d transitions consistent with octahedral geometry for Co(II), Ni(II), and Cu(II) complexes. Overall, the combined spectral, magnetic, and analytical data conclusively establish the formation of stable, six-coordinate octahedral complexes of the synthesized macrocyclic ligand with Co(II), Ni(II), and Cu(II) ions. The study highlights the strong chelating ability of the ligand, the influence of anions on coordination behavior, and the potential applications of such macrocyclic complexes in catalysis, bioinorganic modelling, and material science.
