    A comparative study on the perceived work stress, work-related stressors, and coping strategies of fish vendors in Antique
    Cabigunda, Greshanne J.; Moquera, Mabelle M. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2024-07)
    Fish vending is a common source of income in Antique, Philippines. Fish vendors are classified into two vendor groups: formal vendors who sell inside public markets and informal vendors who sell their products on the streets. Research shows that these groups encounter varied work experiences given their differing working conditions. However, existing research is not enough to describe their stressful work experiences as well as their coping strategies. Thus, this research study aimed to describe and compare the work-related stress of fish vendor groups in Antique and how they cope with it. To address these, a convergent parallel mixed methods design was used. A total of 40 fish vendors with a mean age of 44.70 years, classified as formal (20) and informal (20), served as respondents. Data were gathered using a one-on-one interview with a question guide and a modified survey instrument for levels of perceived work stress (LPWS). Mann-Whitney U analysis revealed no significant difference between the overall LPWS of both groups (W= 4272.50, p>0.05). However, per dimension analysis of results showed a significant difference in the physical work environment dimension (W= 85.50, p<0.001). Conceptual content analysis also indicated that work-related stressors and coping strategies are relatively different between vendor groups and across dimensions. The findings of this research suggest that the physical work environment is a significant dimension that differentiates fish vendor groups’ levels and sources of work stress. Moreover, findings imply that social resources, especially among co-vendors, reduce LPWS.

    Economic analysis of tilapia pond culture in Iloilo
    Arellado, Emily A. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines in the Visayas, 1997-03)
    This paper analyzed the factors affecting production of tilapia pond culture in Iloilo using the production function approach. The study used primary and secondary data. Primary data were gathered from a survey of actual operations of 30 tilapia farmers in Iloilo. Secondary data were taken from the Department of Agriculture in Sta. Barbara, Iloilo, the SEAFDEC and UPV libraries. The production function was specified using the Cobb-Douglas function to identify and explain the factors affecting variations in the output of tilapia. The explanatory variables included in the analysis were: fingerlings stocked (X1), inorganic fertilizers (X2), organic fertilizer (X3), supplementary feeds (X4), farm size (X5), hired labor (X6), miscellaneous operating costs (X7), number of years in tilapia farming (X8) and age of pond (X9). There were six variables found significant in explaining tilapia 'production namely; fingerlings stocked, inorganic' fertilizer, organic fertilizer, farm size, hired labor and age of pond. The F—statistic rejected the null hypothesis which states that no explanatory variables help to explain variations in the dependent variable. Therefore, the alternative hypothesis was accepted that at least one or more of the independent variables affect production. The R2 showed that 92 percent of the variations of the explanatory variables explained the variations in the independent variables. This implies that there exists a relationship between the independent and dependent variables. Fingerlings stocked, inorganic fertilizer and hired labor were used inefficiently by the tilapia farmers. The use of fingerlings stocked should be increased while the use of inorganic fertilizer, organic fertilizer and hired labor should be reduced, if the maximum net returns are to be realized.
