Canonical JSON (keys sorted, no spaces, UTF-8). Its SHA-256 is the hash on chain. The abstract here is gemini shortened, not the author's own text.
{"abstract":"This study used a descriptive method and simple random sampling to determine the economic impacts of Lupac Beach on coastal tourism development in Gumaca, Quezon, based on the perceptions of 100 selected residents. The respondents' profile showed that 32% were aged 21-25 years old, and 51% were male. An even number of respondents from different barangays participated. The study found that respondents generally agreed on the economic impacts of Lupac Beach on coastal tourism development. Specifically, the average mean for the development of local business was 4.11, for infrastructure was 4.08, and for employment opportunities was 4.09, all interpreted as \"Agree.\" The Kruskal Wallis H-Test revealed no significant difference in perceptions based on age and sex. However, when grouped by address, there was a significant difference in respondents' perceptions of the economic impacts of Lupac Beach on coastal tourism development. Recommendations included prioritizing local residents for jobs, improving public facilities, and active youth participation in promoting the beach.","abstract_source":"gemini_shortened","authors":["Michelle Angulo","Maria Celerina Oreta","Melchor Espiritu","Gil Segui"],"date":"2025-08-14","doi":"10.70838/pemj.450110","id":6150,"issue":1,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"8e201385a50231a120c7412b4b5b728cddb0099304f4a8e1620747cdf7034ed2","schema":"scimatic-article/1","title":"Assessing the Economic Impacts of Lupac Beach on Coastal Tourism Development in Gumaca, Quezon","volume":45}
