Item A comparative study on the perceived work stress, work-related stressors, and coping strategies of fish vendors in AntiqueCabigunda, 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.Item The nature of communication and relationship between migrant parents and left-behind childrenCabigunda, Gael J.; Corpus, Hazel Jade L. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2016-05)This study is qualitative in nature which sought to describe the nature of communication between migrant parents and left-behind children and to describe how their communication influenced their relationship and the balance of the family unit despite the physical separation and the distance. The family system’s theory was used as a framework in this study, to better explain the nature of communication and the relationship between migrant parents and left-behind children among transnational families. Twenty-two (22) left-behind children were conveniently sampled to participate in focus group discussions conducted by the researchers. Experiences of left-behind children on migration were captured through the use of an interview guide which included questions pertaining to: (1) the methods used in communication, (2) the problems encountered in communication, (3) the content of the communication and (4) the parent-child relationship. Data was then analysed using thematic analysis. Results showed that the nature of communication and relationship between migrant parents and left-behind children are dependent on: the characteristics of the parent and the child, the methods used in communication, the existing relationship before migration occurred, and the guardian’s role in the triangle relationship. In conclusion, the frequency of communication served as an affirmation of the existing relationship between parent and child. Furthermore, when the parent and child have an open relationship they enjoy a better quality of communication. Communication was also used by parent and child to fulfil their roles and affirm their membership in the family despite physical separation and the distance.Item Antidiarrheal activity of Pterocarpus indicus bark extracts using castor oil-induced diarrhea model on miceCabatea, Norberto C. (Department of Chemistry, College of Arts and Sciences, University of the Philippines Visayas, 2010-04)This study evaluated the antidiarrheal activity of the bark of Pterocarpus indicus (Narra). The crude methanolic extract of the bark was subjected to sequential extraction using hexane, DCM, and ethyl acetate. These extracts were tested for antidiarrheal activity in vitro using the castor oil induced diarrhea model in mice employing charcoal tracing method. Thin Layer Chromatography (TLC) was used in determining the chemical constituents present in every extracts using spraying reagents to aid in the visualization of spots. Crude methanolic extract dosage 200 mg/kg body weight is the comparable dosage to the reference drug loperamide (2 mg/kg body weight). The hexane extract was the most active fraction and 200 mg/kg dosage was more effective than with the positive control loperamide (2 mg/kg). No antidiarrheal activity found in the fraction of DCM and ethyl acetate extracts. Phytochemical screening revealed positive tests for tannins, phenolics, terpenes, cardiac glycosides, saponins and reducing sugars in all fractions. Tests for flavonoids and alkaloids, however, were negative.Item Comparative analysis of the best practices in ecosystem-based watershed planning and management in the Philippines and CanadaCabios, John Paul G.; Untaran, Paul Joseph N. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2015-06)The Philippines is one of the many examples of a developing state vulnerable to natural disaster that erodes soil and water quality. With the continuous evolution of watershed management practices and the growing importance of climate change mitigation, there is a need to reassess the structure, function, and policy approach of the different stakeholders. And due to climate change and anthropogenic impacts, the environment especially watershed and agricultural farms in Canada are greatly affected. Because of this, there is a need to create environmental management practices to mitigate and minimize the effects of climate change and human interventions. The objectives of this paper is (1) to provide an analysis of the best watershed management practices in Canada and Philippines, (2) to identify governance structures and inter-governmental coordination, and (3) to determine planning approaches and community and stakeholder engagement. This paper will discuss generic models of governance in environmental policy and the different approaches to water management in both countries. This paper will also compare the differences between the models and approaches used in the two countries. And lastly, this paper will evaluate the use of watershed management practices in Canada and Philippines in order to find out the most compatible and reliable method or approach of watershed management.Item In vitro antibacterial activity of Hibiscus rosa sinensis leaf extracts against some pathogens associated with urinary tract infectionsCabayao, Coney B. (Department of Chemistry, College of Arts and Sciences, University of the Philippines Visayas, 2011-04)The in vitro antibacterial activity of Hibiscus rosa sinensis leaf ( methanolic, dichloromethane, ethyl acetate, n-hexane, and aqueous ) extracts were studied against Gram-negative (Escherichia coli and Pseudomonas aeruginosa ) and Gram-positive ( Streptococcus faecalis) bacteria. The methanolic extract was subjected to sequential liquid-liquid extraction using solvents of varying polarity and concentrations. Out of the 5 extracts, methanolic and dichloromethane extracts exhibited the highest antibacterial activity as measured using the zone of inhibition. This was followed by ethyl acetate and n-hexane extracts. At 200 mg/ml concentration, all extracts were considered active when tested with E. coli and S. faecalis, and were partially active against P. aeruginosa. The aqueous extract was inactive towards the three bacteria. The 200 mg/ml concentration showed no significant difference when compared with the positive control, amoxicillin (12.51μg/ml). This shows that Hibiscus rosa sinensis exhibits a promising antibacterial activity. Phytochemical analysis of the active fraction- the methanolic extract- showed the presence of alkaloids, tannins, glycosides, saponins, steroids, flavonoids, terpenoids, and anthraquinones. These bioactive components could be responsible for the antibacterial activity of Hibiscus rosa sinensis leaf extracts.Item Alcohol use among out-of-school youth in Iloilo CityCabaluna, Vanessa P.; Eler, Paul Candice Ellen M.; Gazo, Ella Catherine T.; Marla, Mary Ellen J.; Train, Christine Q. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2002-03)The out-of-school youth, 13-22 years old, appears to have one of the greatest risks for alcohol use. This study was conducted to determine alcohol use among out-of-school youth in the City of Iloilo. The subjects of the study were 150 out-of-school youths, randomly selected from 15 barangays of the 6 districts of Iloilo City. Data for this research was gathered using an interview schedule. Results show that one hundred thirty-one (87.33%) out of 150 out-of-school youth respondents had been initiated to alcoholic drinks. Their mean age at alcohol initiation was 15.81. Majority of these respondents usually drink beer (58.78%), followed by gin (13.74%), and tuba/lambanog (12.22%). Other choices include rum and brandy. Factors that influenced the respondents to drink alcohol included friends (67.94%), relatives (12.98%), father (9.16%). Other factors included personal decision, mass media, and mood/problems. Reasons for drinking alcoholic beverages include celebrations of special occasions (30.53%), leisure (18.32%), curiosity (15.27%), and sense of belongingness (12.98%). Other reasons include peer pressure, personal choice and personal problems. Reasons for not drinking include personal choice (47.37%), health reasons (31.58%), family prohibits (15.79%), and religion prohibits (5.26%). Alcohol use is significantly associated with respondents' sex, involvement in organisations or community activities, smoking, and use of prohibited drugs. There is no significant difference between alcohol use and family drinking status & with whom they are staying.Item Microbiological assessment and detection of potentially pathogenic bacteria on three areas along the Iloilo RiverCaballo, John Carlo P. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2011-04)The Iloilo River, which traverses the whole length of Iloilo City, serves as a water source for different human activities hence, subjecting it to a variety of pollutants. Microbial and physico-chemical parameters of the three areas along the Iloilo River (Carpenter’s Bridge, IBRD Bridge, and Dungon Creek) were assessed to in order to provide a quantifiable evaluation of the river’s water quality. The presence of Salmonella spp., Eschericia coli, Streptococcus spp. and Vibrio spp., was also determined. HPC counts indicate very-high to extremely-high levels of bacterial loading (5.31 x 105-l .60 x 106 CFU/lOOmL) among the three sampling areas. Total coliform levels indicated contamination of the river from outside sources, potentially from domestic sewage discharges and run-offs from nearby establishments. The FC: FS ratio suggests contamination mostly came from mixed origins, with the noted exception of Carpenter’s Bridge, which is dominated by human fecal contamination. Minimal variations in physico-chemical parameters were observed for all areas. Significant correlations were found among salinity (p=0.002) and temperature (p=0.042) with TC; between FS with dissolved oxygen (p=0.00), and between FC and temperature (p=0.005). Contamination of the river by organic and fecal matter from animal and human sources provided a suitable habitat for pathogenic bacteria. A considerable quantity of potentially pathogenic bacteria such as; E.coli, Salmonella spp., Streptococcus spp. and Vibrio spp., were isolated from each sampling area. Exposure to these pathogens in drinking and recreational waters poses health risks to local inhabitants and to any individual who would consume water from the riverItem Children of fathers behind bars: Evaluating their perceived social stigma in relation to their levels of self-esteem and social interactionCabarles, Maria L.; Muyco, Rich Girl S. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2008-03)The study aimed to describe the relationship of social stigma experienced or perceived to self-esteem and level of social interaction of children with incarcerated father. Respondents consisted of thirty-two high school student ages 13-17 years old, either currently studying or out of school residing in the rural or urban areas of Iloilo. They were selected using a quota sampling method. Gathering of data was in the form of interview and questionnaire which was answered by the respondents. The study hypothesized that there is a relation between the self-esteem and level of social interaction, there is a relation between self-esteem and social stigma experienced or perceived by the children and there is a relation between the level of social interaction and social stigma experienced or perceived of the children with incarcerated father. Spearman-Rank Correlation (Rs) was used to analyze data. The results showed that only the self-esteem and the level of social interaction of children with incarcerated father has a relationship.Item The relationship of children's concern and the couple's empty-nest stress experiences with their relationship purposeCabarles, Irene Grace S.; Tan, Cesa, Jr. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2006-03)This correlational study aimed to find out whether the degree of children’s concern for their parents and the empty-nest stress experiences of these parents have an effect on their relationship purpose. A total of 40 couples participated in the study. The Children’s Concern Scale, the Perceived Stress Scale and the Relationship Purpose Scale were utilized for the data gathering. Generally, the results revealed that the higher the concern showed by the children to their empty-nest parents, the more likely that the empty-nest couple will focus on their marital relationship. However, the average amount of stress experienced by the empty-nest couples does not have a significant relationship with their relationship purpose.Item Growing up in culture of gambling: Explaining adolescent students' academic performance using the Theory of Planned BehaviorBurgos, Jaclyn Gay S. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2017-06)Integrating lcek Ajzen’s Theory of Planned Behavior, this study seeks to explain the factors that influence the academic performance of adolescent students. In assessing the academic performance: questionnaires for attitudes towards behavior, subjective norm, perceived behavioral control, and intention were administered to adolescent students (n=88) in rural areas of Iloilo. A Pearson-product moment correlation was used to examine the correlation between the factors and academic performance. There were five participants who joined the focused group discussion and their answers provided an indepth connection of the variables. Results of the quantitative analysis stated that attitude towards behavior, subjective norm, and perceived behavioral control are individually correlated with intention but only attitude towards behavior is significantly correlated with academic performance. The results from this study can be used in schools and related government agencies in shaping students to have a more positive outlook with regards to academic performance.
