In Argentine ant-free sites, most of Myrmarachne exhibited all-blackish colouration. In Argentine ant-infested sites, on the other hand, blackish morph decreased, and bicoloured (i.e. partly bright-coloured) morphs increased in dominance. Invasive Argentine ant drives away native blackish ants. Disappearance of blackish model ants supposedly led to malfunction of Batesian mimicry of Myrmarachne.展开更多

The respondents of this research were the two sections comparable with each other who was enrolled in the subject Navigation 3. There were 60 student respondents composed of 30 in the experimental group and 30 in the control group. A validated three item teacher-made problem solving test with 10 points for each correct answer was used as an instrument. The dependent variable was the scores in Navigation 3 and independent variable was the PBL approach. The statistical tools used were mean, standard deviation, Mann-Whitney test, and Wilcoxon-Signed ranks test set at 0.05 level of significance. The effect size was computed to determine the effectiveness of the PBL approach in terms of students＇ performance in Navigation 3. Results showed that in the pretest, though the experimental group had a higher mean than the control group, the Mann-Whitney test showed that the mean scores of the two groups were comparable because the significant value was greater than 0.05. When the treatment was introduced, findings showed that there were significant differences in the Navigation 3 performance in the pretest and posttest of experimental and control groups as well as in the posttests of both groups. It could be inferred that the better performance of the experimental group could be attributed to the intervention where the students were actively involved in the learning process.展开更多

Angelex Arevalo Panes, an alumnus of the then, John B. Lacson Colleges Foundation （Arevalo）, Inc. of Batch 1995 now, John B. Lacson Foundation Maritime University-Arevalo. The story of Capt. Panes tells his family and educational background, career paths, driving force to work efficiently, hardwork, coping strategies, job encounters, edged as first Filipino captain of M/V SKS Tiete, skills as effective team leader, managerial techniques in resolving conflicts under watch, problems and solutions encountered on board, preparations for his sunset life, and his message to all aspiring seafarers. This paper gives glimpse to the life of Philippine＇s modem hero-a seafarer like Capt. Angelex A. Panes and lessons to those who would become seafarers.展开更多
