    Heavy metals (Cr, Cu, Pb, and Zn) concentrations of road-deposited sediments within six public plazas in Iloilo City
    Caceres, Rizza Daphet E. (Department of Chemistry, College of Arts and Sciences, University of the Philippines Visayas, 2011-04)
    Contamination from overland transportation is an unavoidable result of urbanization. Cr, Cu, Pb, and Zn arc common heavy metals introduced to the environment by transportation. Road-deposited sediment (RDS) samples were collected from six public plazas (Villa Plaza, Molo Plaza, Mandurriao Plaza, Plaza Libertad, Lapaz Plaza and Jaro Plaza) in Iloilo City from March 2010 to May 2010. 0.5M HC1 was used as extractant and heavy metals (Cr, Cu, Pb, and Zn) concentrations were determined using Flame Atomic Absorption Spectrophotometer (FAAS). The mean concentrations of Cr, Cu, Pb, and Zn in road-deposited sediments from six plazas were 8.79 ± 1.93, 40.90 ± 24.21, 60.74 ± 22.32, and 164.25 ± 25.0 mg/kg, respectively. Metal enrichment of Cr, Cu, Pb and Zn were approximately xl, x8, x7 and x18 more than the background values respectively. There was no significant temporal variation in metals concentrations of RDS between sampling collections. Generally, RDS from Plaza Libertad has the highest metal concentrations. Cu and Pb metals were highly correlated (R2 = 0.891) indicating possible similar sources. A good correlation (R2 = 0.918) was observed between Pb concentration and the number of vehicles that pass along the plaza per hour. Heavy metal concentrations in sediments from plazas have low hazard quotients but bioaccumulation of metals in the body could cause health effects. Efficiency of digestion procedures varied depending on characteristics, texture and composition of road-deposited sediments. 0.5M HC1 digestion was used because it is simple, cost-effective, time-efficient and it leaches out meaningful amounts of bioavailable metals. Using HC1 as extractant simulates human digestion since human stomach contains HC1 that could leach out metals if road-deposited sediments were ingested.

    An analysis of the factors affecting women's decision to participate in the informal sector of Iloilo City
    Cabrera, Ma. Luz Sophia L.; Gonzaga, Lenny S. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2004-03)
    The study looked into the factors affecting women’s decision to participate in either the informal or the formal sector in the City Proper district of Iloilo City. The study has 126 respondents who were randomly chosen from the four barangays of Iloilo City proper namely; General Hughes, Ortiz, Rizal Pala-Pala I, and Rizal Pala- Pala II. Fifty percent of the respondents were women who are working in the informal sector as they are the focus of the study. The other half of the respondents is the women working in the formal sector of the economy. The dependent variable is a dichotomous variable assuming the value of 1 if the respondent prefers working in the informal sector and 0 if otherwise. The independent variable identified for the study are the: age of the respondent, number of years in school, number of children below 7 years of age in the household, civil status, household size, status in the household, household annual income, respondent’s other sources of income. The equation was estimated using binary logistic regression. Multivariate analysis revealed that age of respondent, number of years schooling, number of children below 7 years of age in the household and the status in household are significant within the 5% level of significance. Moreover, the chi- square value of 40.88 which is also significant at 5% level shows that the model is significant in determining the factors affecting the decision to participate in either the informal or the formal sector.

    Status of online selling in Iloilo City
    Blanco, Kathleen Kay T.; Nardo, Celina B. (Division of Humanities, College of Arts and Sciences, University of the Philippines Visayas, 2013-04)
    From the advent of the Internet now comes its commercialization. E-commerce has emerged under which online selling is classified. This is a descriptive study which used survey interviewing method in order to assess the status of online selling in Iloilo City. In the process of data gathering, the snowball sampling was used in determining the respondents. Supplemental data from Department of Trade and Industry (DTI) - Iloilo, Bureau of Internal Revenue (BIR.) - Iloilo and Business Licensing and Permit Office (BPLO) of Iloilo City were also gathered for reference. Major findings of the study show that the number of online sellers in Iloilo is growing since 2010 and these sellers use social networking sites and online classified ads site for online selling. The result of the study also shows that online sellers are not fully aware of the laws that affect online selling and the aforementioned government agencies lack regulation over the said form of business. The researchers discern the need for policy convergence just as digital convergence is occurring.

    Relationship between media exposure and attitude of Iloilo City Junior High School students towards indigenous peoples
    Amon, Abigail; Garzon, Ma. Mercedes (Division of Humanities, College of Arts and Sciences, University of the Philippines Visayas, 2017-05)
    This research discusses the relationship between media exposure and the attitude of selected Iloilo City public junior high school students towards the indigenous peoples. Three hundred junior high school students from Bo. Obrero National High School, Iloilo City National High School, Mandurriao National High School, Ramon Avanceña National High School, and SPED - Integrated School for Exceptional Children served as respondents to a five-part questionnaire that included demographics, exposure to media and IPs, attitude, additional questions regarding the relationship between their media exposure and their attitude towards IPs, and the information they received and wished to receive from media. The researchers found that students were most exposed to online media and that they had low exposure to mediated content on indigenous peoples on all media platforms. It was concluded that respondents had an overall positive attitude towards indigenous peoples. Moreover, both the media industry and the educational system should be more responsible in supporting the IPs through wider media coverage and introduction to more media platforms.
