Perceived stress, social support and coping strategies on retired teachers' psychological well-being
Barcelona, 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.
Homosexual organization networking strategies and abilities in a participatory democracy: A case study of butterfly brigade's advocacy campaign on STI/RTI HIV/AIDS prevention in Aklan province
Barluado, Bonifar A., Jr. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2008-03)
This is a study about Butterfly Brigade, a homosexual organization in Aklan Province. It explains how Butterfly Brigade interacts with the local government within the venues and spaces provided for it. It describes how Butterfly Brigade forms linkages and networks of support with local government units and other organizations in formulating strategies and in mobilizing for their goal under various cooperative frameworks.
The mode of data collection was through personal interviews and also includes the information from written materials and organizational files of the Butterfly Brigade. The study was conducted in Boracay Island, Municipality of Malay where Butterfly Brigade has a considerable number of activities related to its AIDS Awareness program.
Butterfly Brigade interacts with the local government by being a member of the Provincial AIDS Council (PAC). The Local Government of Aklan provides Butterfly Brigade a legitimate role in policy-making through PAC. Butterfly Brigade creates a network of linkages with the Provincial Government of Aklan, UNFPA, DKT-Philippines, school administrations, and other civic organizations by conducting information dissemination activities under various AIDS and STD related campaigns. Conservative institutions like the Catholic Church have opposed Butterfly Brigade activity.
Gonadal maturation Stages of Pinkfingered Vinegar Crab Episesarma chengtongense (Serene and Soh 1967) from Capiz, Philippines
Barredo, Elilyn Farrah Belle B. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2015-06)
The pink-fingered vinegar crab Episesarma chengtongense is a growing fishery resource in the mangrove areas of the Philippines and may have potential for aquaculture and stock enhancement. To determine the gonadal maturation stages for both male and female for this species, a study was conducted from February to May 2015 of the pink-fingered crab from Capiz, Philippines. The determination of the gonadal maturation stages was based on the gross morphology and histological characteristics of the male and female gonads. In both sexes, gonad activity occurred throughout the study duration but for females, the peak egg bearing month was in May (87%). Body sizes of ovierous females were from 31.9 - 42.3 mm (CW). The greatest prevalence of ovigerous females was in the size range of 35-39 mm CW; the lowest percentage at 40-44 mm CW. Male crabs with mature testes were consistently high (70- 100%) in the four months duration of the study. The smallest female carrying eggs was 31.9 mm CW. Four stages of ovarian maturation were identified namely: developing (Stage II) with a yellow colored gonad, ripe (Stage III) with orange colored gonad, mature (Stage IV) with brown colored gonad and spent (Stage V) with light brown colored gonad. Two stages of male gondal maturation were identified namely immature (Stage I) with translucent to off white testes and mature.(Stage II) with creamy white testes.
A community study of mangroves in Brgy. Caliling, Cauayan, Negros Occidental
Barredo, Sherry Marie P. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2000-03)
The species distribution of the mangrove community in Brgy. Caliling, Cauayanz Negros Occidental was studied using the transect line plot method with three plots for each of four stations established. Both stations 1 and 4 were located landward, while stations 2 and 3 were located seaward. Community structure Is described in terms of the following parameters; basal area, number of trees per hectare, importance value, relative density, relative frequency, frequency of species and relative dominance. Variations in these parameters are correlated with physico-chemical factors such as the air, water and soil temperature, water depth, salinity and pH.
Ten true species were found In the mangals of the coastal environment of Brgy. Caliling, Cauayan, Negros Occidental. They were Avicennia aiba, Avicennia Janata, Avicennia manna, Campostemon phiiHpinensis, Excoecaria agallocha, Osbomia octodonta, Nipa fruticans, Brugeria cylindrica, Rhizophora apiculata and R. mucronata.
Standard Basal Area was highest in Station 3 with 7.54 m/ha. In terms of zonation, the landward zone was found to have the highest Stand Basal Area with 11.15 m/ha. Station 2 had the highest density value of 33.92 %, whereas in terms of zonation, both the middle and seaward zone had the density value of 36.20 %.
Avicennia marina was found to be the most dominant species and was observed to occupy sites with hypersaline conditions, in silty clay to muddy substratum, which may or may not be inundated by tidal flow most of the time.
Bacteriological survey and detection of Escherichia coli, Salmonella spp., Streptococcus spp., and Vibrio spp. in bottom sediments from two sites in Iloilo River
Barrera, Christopher (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2010-04)
Bacterial contamination in the Iloilo river occurs because of various human activities. The assessment of the river was done using microbiological parameters (HPC, TC, FC, and FS) for 7 months in Sooc Bridge and Carpenter’s Bridge using bottom sediments for samples. Sediment was used because bacteria accumulate over time in the sediment due to high amounts of organic and inorganic matter in the substrate and this leads to better survivability of bacteria. The values obtained from microbiological parameters investigated are generally higher in Sooc Bridge. HPC results show that the higher mean value was in Sooc Bridge(7.43 x 108 CFU/lOOg). The levels of TC on both sampling sites ranged from 9.5 x 102to 2.40 x 104 CFU/100g. For TC, Sooc has the higher mean (1.76 x 104 CFU/lOOg) for 7 months. FC values ranged from 3.0 x 101 to 2.4 x 104 CFU/lOOg. Sooc bridge has the higher mean(1.17 x 104 CFU/lOOg) between the 2 sites. Lastly, the FS value range from 2.9 x 103 to 2.4 x 104 CFU/lOOg. Also, Sooc Bridge has the higher mean value (1.58 x 104 CFU/lOOg). There are no significant differences on the microbiological parameters used in each site. The FC/FS ratio revealed that mixed fecal materials contaminate the river. Among the four pathogenic bacteria detected, Salmonella spp. was the most abundant for 7 months (63-65%) and E. coli was the least abundant(>l%). Based on the criteria on sediment quality evaluation, there is little to moderate loading of organic and inorganic matter.
