Assessing interlanguage pragmatic competence on speech acts in a Filipino ESL context.
(Corpus Pragmatics, 2023-02-27) Budeng, Rinarose B.; Merza, Hartwell Norman M.
This study aims to assess the pragmatic competence of Filipino ESL learners along comprehension and production through pragmatic assessment tools that are contextualized to the local needs of Filipino ESL learners. The tools were developed in several steps such as generation of speech acts situations, likelihood investigation, organization of situations, checking for content validity, and checking for reliability. The developed research instruments were a multiple-choice tool for the pragmatic comprehension test and a WDCT for the pragmatic production test. The situations for the pragmatic tools were contextualized to Filipino ESL learners. The tools were administered to 70 AB English majors. The results revealed that the Filipino ESL learners’ level of pragmatic comprehension is high while their pragmatic production is slightly off but acceptable as rated by American English native speakers. The results imply that there is still a need to promote Filipino learners’ pragmatic competence as a crucial part of their communicative competence.
Lift yourself up or dust yourself down:
(The Asian EFL Journal, 2019) Lachica, John Mark
This phenomenological study explored and described the lived experiences of nine university students in their speech classes through video-recorded performances, survey, and semi- structured interview. This study yielded three manifestations of speaking anxiety namely physiological, cognitive, and linguistic manifestations. Among the causes and types of anxieties experienced by the participants are psychosocial anxiety, anxiety related to the use of the target language, and anxiety related to limited exposure to the target language. Moreover, reminiscence, relearning, and remediation were three of the coping mechanisms used by the student participants in dealing with their anxieties. Findings of this qualitative inquiry and observation may not only contribute to the existing literature on speaking anxiety but may also provide insights that probe on the practices, lived experiences and performances of university students when exposed to such phenomenon in acquiring a second language. Meanwhile, despite the fact that English speaking anxiety is a common phenomenon in the teaching of English, teachers do not always identify anxious students, and often attribute their unwillingness to participate in speaking tasks to factors such as lack of motivation or low performance.
Taxonomic evidences supporting the establishment of ‘sibujing', a traditional condiment crop from the Philippines, as Allium chinense G.Don
(Nordic Journal of Botany, 2023-10-06) Vera Cruz, Juan Rodrigo A.; Gentallan, Renerio P.; Bartolome, Michael Cedric B.; Calimpang, Ison A.; Quiñones, Kristine Joyce O.; Manting, Muhmin Michael E; Madayag, Roselle E.; Lalusin, Antonio G.; Hernandez, Jose E.; Manuel, Ma Carmina C; Endonela, Leah E.; Borromeo, Teresita H.
'Sibujing' is an emerging crop species in the Philippines with recorded traditional use as condiment in localized areas in Mindanao. However, its taxonomic identity is confused as it has been attributed to various taxa of Allium. We characterized the morphological, phytochemical and molecular characteristics of a ‘sibujing' accession to establish the taxonomic belonging and correct species name of the crop and elucidate its baseline characteristics for its continued utilization. Through next‐generation sequencing, we assembled the quadripartite genome of a ‘sibujing' accession from Zamboanga del Norte. The generated chloroplast genome revealed 100% similarity to the earlier established 152 525‐bp‐long A. chinense G.Don. plastome from China. Morphological characteristics also support this identification as both bears leaves with hollow 3–5‐angled cross‐sections, scapes that are terete and solid, and distinctly toothed filament base. Saponins were also detected from its methanolic extract. Phylogenetic reconstruction based on the sequenced ITS region, a nuclear barcode, suggested that the species was closest to taxa belonging to Allium sect. Sacculiferum subg. Cepa, further supporting its potential identity with A. chinense. Using a separate accession from a different locality in the Philippines, these findings were validated as the chloroplast genome assembled, phytochemical and morphological characteristics recorded were similarly established as close to A. chinense. This is the first definitive record of an Allium species from sect. Sacculiferum in the Philippines.
The sentiments of Philippines’ underground artist and technology intervention
(Institute of Physics Publishing, 2019-03) Ventayen, R. J. M.; Kupsch, S.; Palaoag, T. D.
Listening to music is a significant and essential part of the daily life of many citizens, it is not just a hobby, but it reflects one's personality. In the new age of technology, several ways of playing and producing music became a trend. Thus cultural and underground artist in the Philippines is still left behind. The objective of this study is to determine the current situation of the unsigned artist in the Philippines by means of interviewing unsigned artist, bands, and independent music practitioners. This study uses the descriptive method of study that answered the questions regarding the current situation and sentiment of the unsigned artist. The study also discussed the technological trends could be considered to address problems of the Unsigned artist based on the current situation, and the layout of the proposed portal and lastly the overview of the architectural model that shall be adopted in designing the proposed portal. Based on the result of the study, the Unsigned Artist are in need of a platform for proper distribution of music. In order to satisfy the needs, this paper also discusses the overview of the proposed portal.
Sensitivity analysis of dengue model with vector control
(International Journal of Mathematics and Computer Science, 2024-06) de Leon, Ronica M.
Dengue remains a threat to human health, and epidemics can still occur, especially in rainy seasons. Addressing the need to implement adequate preventive interventions requires a better understanding and assessment of the vector control strategies’ impact on host and vector populations. In this study, the sensitivity of state variables of a dengue model with vector control strategy was analyzed. Using the model and estimated parameters from a data set on dengue cases, sensitivities of state variables were solved. Relative sensitivities revealed that application of chemical control has a greater impact on decreasing the number of dengue cases than the non-chemical control but using both types can help mitigate the increase of cases.
