    Cost and return analysis of milkfish operations in different farm sizes in Barotac Nuevo, Iloilo
    Belgira, Gay Nanette (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1996-07)
    Milkfish (Chanos chanos) is the most important pond cultured fish specie in the Philippines. Barotac Nuevo, where the study was conducted, is among the most productive in the province of Iloilo in terms of milkfish culture. Cost and Return Analysis of Milkfish Production evaluates the economic performance of 30 milkfish farms in Barotac Nuevo, Iloilo. The economic performance of milkfish farms were assessed using profit, revenue, return on investment, rate of return on operating cost, and payback period. Investment and cost structure were also presented. Comparative analysis was done by farm size namely; small farms (less than 5ha), medium farms (5.01 to 20ha) and large farms (above 20ha). Farm investment increased as farm size increased. The highest yield per hectare per crop was obtained by medium farms (708.86kg) followed by large farms (566.76kg) and small farms (394.16kg). For all farms, economic profit decreased as fann size increased on a per farm basis. Small farms had an economic profit of P7,525.25. Medium farms had P55,157.66 while large farms had P131,575.59. Results showed that variable cost of medium farms(21,056.97) on a per hectare basis was higher than that of the large farms(20,298.67) while fixed cost of all farms on a per hectare basis decreased as farms size increased. Opportunity cost of farms on a per hectare basis decreased as farm size increased. Small farms had the lowest return on investment (14.30%) followed by medium farms (30.68%) and large farms (42.31%). Rate of return on operating cost for small farms was 56.03% while medium farms had 26.53% and large farms had 13.14%. Payback period of all farms decreased as farms size increased. Small farms had 6.99 years, medium farms had 3.29 years and large farms had 2.36 years. From all economic indicators presented, milkfish pond culture remains a profitable business venture in Barotac Nuevo, Iloilo. Small farms were found to be productive due to the close farm supervision devoted by owners themselves, but medium farms were found to be most profitable farm size to operate in milkfish pond culture in Barotac Nuevo, Iloilo. Large farms has lower yield because of the large area it occupies that an operator can hardly check all areas.

    Attributions on the development of homosexuality and factors that lead to non-disclosure of sexual orientation among male covert homosexuals
    Bansuelo, Florence S. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1996-03)
    The study aims to know the attributions on the development of homosexuality by male covert homosexuals, their reasons for keeping their sexual orientation hidden, and whether there are common personality characteristics among them. The researcher used in-depth interviews and the test Panukat sa Ugali at Pagkatao of Enriquez et al. to measure respondents’ personality characteristics. The respondents of this study consist of ten male covert homosexuals. The findings showed that the major attributions on the development of homosexuality are; early childhood sexual experience with older males, friends were mostly girls during childhood and adolescence, “it just happened”, a feeling within themselves that they are attracted to males. According to the respondents, fear of parental and societal rejection are the dominant reasons of their covert homosexuality. The personality test results showed that they are; faithfill, responsible, unreasonably obstinate, and have initiative. These were not classified as the traditional female or male stereotypes. Their attributions on the development of homosexuality are more of the interaction of biological and learned factors. Fear of rejection leads them to hide their sexuality.

    Group study vs. individual study: A comparison of effective study technique
    Bang-as, Erlie P.; Toles, Elohai N. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1998-03-31)
    This study was an attempt to find out which of the two study techniques is effective: group study or individual study. It also sought to know which of the two academic groups performed better in a group study or in an individual study. The respondents were 60 students from the Biological and Social Sciences Divisions. Subjects were selected using the simple random sampling. The design was a 2 (Group study and Individual study) x 2 (Biological Sciences and Social Sciences) factorial design and this tested three hypotheses; (1) To find out if students perform better when they study in groups than when they study alone; (2) To find out if Biology students perform better than Social Science students; (3) To know if Biology students perform better than Social Science students when they study in groups than when they study alone The researchers used the 2x2 Analysis of Variance in the analysis of the data. The results were obtained by using the ANOVA and F test was used to test the hypotheses. The results revealed that (1) students who studied in groups performed better than those who studied individually, (2) Biology students performed better than Social Science students and (3) there was an interaction between study techniques and the academic groups.

    The relationship between Mathematics anxiety and test performance in Mathematics of secondary school students
    Atienza, Quintin G., II; Elisterio, Diogel (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1998-03-13)
    The math anxiety and math test performance of 192 secondary school students from Palaca-Damilisan National High School were assessed using a math anxiety questionnaire and a math test. This was done to find out the effects of math anxiety on high school students’ math test performance. Sex and year level differences on math anxiety and math test performance were also investigated using the analysis of variance. Findings reveal that math anxiety affects math test performance negatively. No statistically significant sex differences were found in both math anxiety and math test performance. No statistically significant year level differences were found in math anxiety. Year-level differences were found to be statistically significant in math test performance. Year level math test performance means showed a decreasing pattern from first year to third year but the means went up in the third year. Tukeys HSD showed that significant differences were coming from the differences in the means of the first and second year levels and the first and third year levels.

    Effect of positive mood on the children's impression-formation judgement
    Agrazada, Divine Grace (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1996-04)
    The study was conducted to determine if positive mood enables children to form positive judgments rather than negative judgments. The study was based on a two—randomized group design. Experimental group was induced in a positive mood and the control group was manipulated with a neutral mood. Neutral mood was also induced to a group of participants to provide a control condition for aid in interpretation of the results. The researcher induced mood through film showing. This method appeared to be the most suitable mood—manipulation technique in the present circumstances. With children , In particular as subjects, videotaped films represent a most suitable and familiar medium for influencing mood. After mood manipulation was completed, the subjects were shown pictures of different persons. These persons served as stimulus characters. Each of the stimulus characters was rated on a IO—centimeter scale as being more closely related to one or the other pair of opposite traits. Thus, participants were asked to write a small vertical line on the 10—centimeter scale to indicate their rating. Results did not show enough evidence for the researcher to conclude that a significant difference in impression—formation judgment will come differentially from positive mood and neutral mood. Based on the findings, children with positive mood and neutral mood both have positive judgments rather than negative judgments. Therefore the researcher concludes that transient mood has no pronounced effect on impression—formation judgment on this study .
