Item Sources of stress, coping strategies and social support among seafarers of Leon, IloiloBatin, Hazel C.; Torilla, Hanna Mae C. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2009-03)The study sought to determine the sources of stress, coping strategies, and sources of social support of seafarers while they are on board. Twenty-three (23) male seafarers served as respondents, they were chosen using the convenience sampling. Questionnaires were utilized to study the variables under investigation. Results showed that seafarers faced problems on board related to their work, emotions, family and their work environmental adjustment. When it comes to managing stress on board, respondents used emotion-focused coping rather than problem-focused. They revealed that they received support from their friends and significant others, but their families were their primary social support.Item Perceived stress, social support and coping strategies on retired teachers' psychological well-beingBarcelona, Mary Racelyn T. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2015-05)Retirement poses significant changes in the lives of the old age population. Along with this are changes in social networks, activities and life outcomes. To examine perceived stress, social support, coping strategies and psychological well-being among retired teachers in Tigbauan, Iloilo, qualitative and quantitative measures were conducted to 41 retired teachers. In general, retired teachers perceive low levels of stress. Factors that contribute to perceived stress are health conditions, financial concerns, family problems and current activities. Social support, which is provided primarily by family and friends, is experienced in high levels. In terms of coping, emotion-focused coping is engaged in by the majority. The leading specific coping strategy they employ is praying or going to church. The majority experience positive levels of psychological well-being, which can be predicted using the variable of social support, as revealed by regression analysis.Item Road widening: The story of role, place attachment, appraisal, coping, and stressAbogado, Maria Liezl Joy; Caños, Mary Jane (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2016-05)This study wanted to determine if social roles, place attachment, appraisal and coping influence the level of stress of those affected by the road widening program using the Transactional Theory of Stress. Respondents (n= 123) were administered various composite measures and key informants were interviewed. Results indicate that those with affirmative place attachment had greater stress levels, as well as when the situation is appraised as threatening. The study lend partial support to predictions of the framework used. Recommendation of the study points to greater efforts from the government in conducting major social impact assessment (SIA) regarding the construction of road projects and providing assistive programs, not only limited to financial compensation but also attends to peoples' wellbeing and lifestyles.Item Assessment of induced stress as schemes for selectively removing fish with opercular deformities in hatchery produced milkfish (Chanos chanos) seedsCordero, Christian P. (College of Fisheries and Ocean Sciences, University of the Philippines Visayas, 2015-06)The effects of different types of induced stress were tested as schemes for the elimination of fish with opercular deformities in hatchery produced milkfish seeds. Salinity and pH were used as the main stressors for milkfish larvae of different ages. Induced salinity stress was initially tested on larvae at 15 days post-hatch (dph) by directly transferring the larvae from its rearing water salinity of 32 ppt to salinities of 10 ppt, 25 ppt, 35 ppt and 45 ppt. Almost all of the larvae subjected to salinity stress dies, hence, it was deemed necessary to examine the influence of handling stress and to determine the age of larvae that could tolerate handling. Larvae of different ages (from 10 dph to 22 dph) were thus subjected to handling stress by collecting them from the mass rearing tank and transferring them to 1000 ml beakers where survival was monitored. Results showed that milkfish larvae were able to withstand handling stress beginning 21 dph. Considering that milkfish fry (21 dph) are already known to tolerate direct transfers to various salinities, the next experiments were focused on pH stress. The suitability reduced or increased pH as stressors were initially tested by directly transferring larvae from normal seawater (pH 7.50) to acidic water (pH 6.5-7.0) and basic seawater (pH 8.0-8.5). Results revealed several advantages of reducing pH levels over increasing pH levels, which included the comparably higher larval survival, the lesser amount of chemicals required to change pH levels and the corresponding cost of these chemicals. A range finding test was then conducted to determine the optimum pH that could selectively remove fry with opercular deformities by directly transferring fry reared in normal seawater (pH 7.50) to seawater with reduced pH: Trt 1-pH 6.5; Trt 2-pH 6.6; Trt 3-pH 6.7; and Trt 4-6.8. Larval mortalities were recorded after 1 h, then 25% water change was done for all treatments which were monitored further for mortalities after 2h, 3h, 5h, and 24h. The surviving larvae from all the treatments were reared further for 18 days (until 40 dph) in order to monitor opercular deformities which can observed only when the larvae have metamorphosed into juveniles. Results showed that a sudden drop in pH of normal seawater to pH 6.5-6.7 selectively removed all the fish with opercular deformities in hatchery produced milkfish seeds; at such pH range, more than 90% survival of milkfish fry was obtained with this batch of larvae and all the surviving fish had no opercular deformities.
