Gaze Collaboration Patterns Of Successful And Unsuccessful Programming Pairs Using Cross-Recurrence Quantification Analysis, Maureen Villamor, Ma. Mercedes T. Rodrigo

Department of Information Systems & Computer Science Faculty Publications

A dual eye tracking experiment was performed on pairs of novice programmers as they traced and debugged fragments of code. These programming pairs were categorized into successful and unsuccessful pairs based on their debugging scores. Cross-recurrence quantification analysis (CRQA), an analysis using cross-recurrence plots (CRP), was used to determine whether there are significant differences in the gaze collaboration patterns between these pair categories. Results showed that successful and unsuccessful pairs can be characterized distinctively based on their CRPs and CRQA metrics. This study also attempted to interpret the CRQA metrics in relation to how the pairs collaborated in order to …

Skillful Disposition And Responsiveness In Mental Imagery, Christopher Joseph G. An

Philosophy Department Faculty Publications

This paper aims to explore and expand on Wittgenstein’s remarks on the nature of mental imagery. Despite some rather cryptic passages and obvious objections, his notion of mental imagery as possessing a constitutive (and not merely added) element of expressive thought and conceptuality offers critical insights linking perceptual capacities with our shared practices. In particular I seek to further develop Wittgenstein’s claim that perceptual impressions presuppose a “mastery of a technique.” I argue that this sense of technique, understood as acquired conceptual capacities, can explain and capture the rich and varied spectrum of expressive visual content that can be accessed …

The Biosorption Of Lead From Aqueous Solutions By A Wood-Immobilized Fungal Biosorbent, Zomesh A N Maini, Niña Therese B. Flores, Enrico P. Muñoz

Biology Faculty Publications

Lead [Pb(II)] biosorption capacities of immobilized Talaromyces macrosporus on Moringa oleifera L. wood were compared against pure fungal and pure M. oleifera biomass. A Pb(II) contact test of 1000 ug/mL show similar Pb(II) removal of non-immobilized fungal biomass (F) and powdered wood colonized with fungi (WP+F), with WP+F producing more biomass. Powdered sorbents had higher Pb(II) uptake compared to whole sorbents analyzed through ICP-AES, possibly due to increased surface area for Pb(II) binding. FTIR analysis of the F, WP, and WP+F identified hydroxyl, amino, carbonyl, and sulfhydryl functional groups which constitute probable Pb(II)-affinitive binding sites. The biosorbents tested in a …

Assessment Of Cytotoxic Activity Of Five Common Philippine Medicinal Plants Using Brine Shrimp Lethality Assay, Lloyd O. Balinado, Merab A. Chan

Biology Faculty Publications

A wide variety of plants in the Philippines are used to address several medical ailments; however, many of which have not yet undergone thorough pharmacological studies. The problem on the possible side effects caused by these medicinal preparations has, therefore, increased the interest in validating their safety for human use. The present study was conducted to determine the cytotoxicity of five common local medicinal plants. Annona muricata L., Cymbopogon citratus DC., Graptophyllum pictum (L.) Griff, Jatropha curcas L., and Piper betle L. were selected and subjected to crude aqueous leaf extraction. Extracts were then investigated for cytotoxicity potential using brine …

Filipino Postmodernity: Quo Vadis?, Romualdo E. Abulad

Philosophy Department Faculty Publications

In this paper, Romualdo Abulad initially presents variations of postmodernity as distinct historical breaks which feature paradigmatic shifts that lead us to a new beginning. Postmodernity, as Abulad shows, is characterized by a radical openness; this leads him to argue that postmodernity as an event occurred in different moments in the history of thought, from ancient to contemporary. In what seems to be a dialectical description of history, he maintains that an opportunity for a break occurs when the inherent limitations and deficiencies of the prevailing status quo emerge, and as a result, ignite the tensions between the preservation of …

Pilosopiyang Pinoy: Uso Pa Ba? (The Relevance Of Filipino Philosophy In Social Renewal), Romualdo E. Abulad

Philosophy Department Faculty Publications

This paper evaluates the titular question and features a summative evaluation and critique of the works and contributions of Leonardo Mercado, Dionisio Miranda, Albert Alejo, Rolando Gripaldo (1947-2017), and Florentino Timbreza to the anthropological and cultural approaches that form a significant part of the discourses on Filipino philosophy. In this piece, Abulad maintains, as in his other writings, that any strict emphasis with regard to methodology restricts the true potential of Filipino philosophy. He buttresses this assertion by invoking postmodernism's 'incredulity towards metanarratives' We should be skeptical about the metanarrative of Filipino identity for it is precisely our rootlessness that …

Reader Response Theory: Students’ Encounter And Challenges With E- Literature, Ma. Junithesmer D. Rosales, John Paolo Sarce

English Faculty Publications

This paper investigated the overall experience of learners with e-literature (e-lit). E-lit as a new form of economy in the field of literature and humanities prompted authors and scholars to create newborn sites of learning — videograph fiction, kinetic poetry, text tula (hyperpoem), and hyperfiction. Thus, the digitization of resource materials in literature led the researchers to investigate the outer circle of some of these new born sites by focusing on the following: readers and their experiences on understanding and learning through e-lit; textual which is concerned with performance and complexities of using this new form of literature; and cultural …

Characterizing Instructional Leader Interactions In A Social Learning Management System Using Social Network Analysis, Orven E. Llantos, Ma. Regina Justina E. Estuar

Department of Information Systems & Computer Science Faculty Publications

Online learning environments are designed with specific users and respective roles in mind. However, for social systems that thrive on the interaction between and among users, important features are developed based on relationships that evolve over time. Typical learning management systems are designed with the teacher and the student as primary users of the system. my.eskwela is a social learning management system that has been designed for use in public schools in the Philippines with the inclusion of an additional user, the school administrator. Although administrators influence on student learning through mediated effects of instructional leadership, pieces of literature are …

On Finding Two Posets That Cover Given Linear Orders, Ivy Ordanel, Proceso L. Fernandez Jr, Henry Adorna

Department of Information Systems & Computer Science Faculty Publications

The Poset Cover Problem is an optimization problem where the goal is to determine a minimum set of posets that covers a given set of linear orders. This problem is relevant in the field of data mining, specifically in determining directed networks or models that explain the ordering of objects in a large sequential dataset. It is already known that the decision version of the problem is NP-Hard while its variation where the goal is to determine only a single poset that covers the input is in P. In this study, we investigate the variation, which we call the 2-Poset …

Aerosol Particle And Black Carbon Emission Factors Of Vehicular Fleet In Manila, Philippines, Leizel Madueño, Simonas Kecorius, Wolfram Birmili, Thomas Müller, James Bernard Simpas, Edgar Vallar, Maria Cecilia Galvez, Mylene Cayetano, Alfred Wiedensohler

Physics Faculty Publications

Poor air quality has been identified as one of the main risks to human health, especially in developing regions, where the information on physical chemical properties of air pollutants is lacking. To bridge this gap, we conducted an intensive measurement campaign in Manila, Philippines to determine the emission factors (EFs) of particle number (PN) and equivalent black carbon (BC). The focus was on public utility jeepneys (PUJ), equipped with old technology diesel engines, widely used for public transportation. The EFs were determined by aerosol physical measurements, fleet information, and modeled dilution using the Operational Street Pollution Model (OSPM). The results …

Making Sense Of The City: Public Spaces In The Philippines, Remmon E. Barbaza

Philosophy Department Faculty Publications

Making sense of the City is a collection of essays from scholars in the humanities and the social sciences examining the city within the Philippine context. With Metro Manila bursting at the seams, as tensions continue to intensify and more intractable problems arise than those that are being solved, it becomes a matter of survival for all stakeholders to come together and shape the future of the city.

Mapping 123 Million Neonatal, Infant And Child Deaths Between 2000 And 2017, Roy Burstein, Simon I. Hay, Veincent Christian F. Pepito, 556 Co-Authors

Ateneo School of Medicine and Public Health Publications

Since 2000, many countries have achieved considerable success in improving child survival, but localized progress remains unclear. To inform efforts towards United Nations Sustainable Development Goal 3.2—to end preventable child deaths by 2030—we need consistently estimated data at the subnational level regarding child mortality rates and trends. Here we quantified, for the period 2000–2017, the subnational variation in mortality rates and number of deaths of neonates, infants and children under 5 years of age within 99 low- and middle-income countries using a geostatistical survival model. We estimated that 32% of children under 5 in these countries lived in districts that …

The City As Illusion And Promise, Remmon E. Barbaza

Philosophy Department Faculty Publications

In The City as Illusion and Promise, the author examines the claim (by Henri Lefebvre, and later David Harvey) that the city no longer exists, at least as we know it. What we have instead is merely an illusion, something that Martin Heidegger also implies in some of his later writings, notably his seminal work on the essence of technology. In confronting such an extreme proposition, the author first raises a conceptual problem: Is the city a city insofar as it is not a province? And vice versa? But the conceptual problematic of course is also manifested in actual material …

As Aschenbach ('Who Setting Out To Voyage Must Have Imagined Which Shores To Avoid'), Mark Anthony Cayanan

English Faculty Publications

The poem is part of a manuscript I am currently working on, which is my attempt to project a mode of disclosure, even as the method of composition, involving the liberal extraction and combination of passages from several urtexts, works against this seeming tonality. The poem loosely channels the consciousness of Gustav von Aschenbach. Among the intertexts I've used are Death in Venice by Thomas Mann, translated by Stanley Appelbaum

Laser Irradiation Of Mung Bean (Vigna Radiata L.) At Two Wavelengths For Enhanced Seedling Development, Rayno Vic B. Janayon, Raphael A. Guerrero

Physics Faculty Publications

Two laser sources operating at wavelengths of 632.8 nm (He-Ne) and 488 nm (Ar+

) are used in examining the effects of coherent, low-power, continuous wave exposure on the development of Vigna radiata L. Presowing laser irradiation of seeds leads to an improvement of mung bean seedling characteristics, with increased values of hypocotyl length (an increase of up to 22.5%), root length (an increase of up to 28.8%), and seedling mass (a maximum increase of 29.2%). Measured parameters between seedlings from laser-irradiated seeds and from control samples are statistically different at a level of significance equal to 0.05. For both …

Materials Selection Of 3d Printing Filament And Utilization Of Recycled Polyethylene Terephthalate (Pet) In A Redesigned Breadboard, Mark Keanu James E. Exconde, Julie Anne A. Co, Jill Z. Manapat, Eduardo R. Magdaluyo Jr.

Goal 12: Responsible Consumption and Production

The demand for a novel and sustainable alternative materials for 3D printer filaments has been knowingly increasing. One alternative source for the filament is to reuse and recycle post-consumer plastic products, which is also a compelling approach to conserve energy and sustain the environment. Thus, this study is focused on the materials selection of virgin polymer resins and recycled post-consumer plastics for use in 3D printer filaments. A multi-criteria decision method of Elimination and Choice Expressing the Reality (ELECTRE) was utilized to determine the best materials for 3D printer filaments. The study has shown that the virgin low-density polyethylene (LDPE) …

Reoptimization Of The Consensus Pattern Problem Under Pattern Length Modification, Jhoirene B. Clemente, Proceso L. Fernandez Jr, Richelle Ann B. Juayong, Jasmine A. Malinao, Ivy Ordanel, Henry N. Adorna

Department of Information Systems & Computer Science Faculty Publications

In Bioinformatics, finding conserved regions in genomic sequences remains to be a challenge not just because of the increasing size of genomic data collected but because of the hardness of the combinatorial model of the problem. One problem formulation is called the Consensus Pattern Problem (CPP). Given a set of t n-length strings S = {S₁,..., S_t} defined over some constant size alphabet Σ and an integer l, where l ≤ n, the objective of CPP is to find an l-length string v and a set of l-length substrings si of each Si in S such …

Local And Global Color Symmetries Of A Symmetrical Pattern, Ma. Louise Antonette N. De Las Peñas, Agatha Kristel Abila, Eduard C. Taganap

Mathematics Faculty Publications

This study addresses the problem of arriving at transitive perfect colorings of a symmetrical pattern P consisting of disjoint congruent symmetric motifs. The pattern P has local symmetries that are not necessarily contained in its global symmetry group G. The usual approach in color symmetry theory is to arrive at perfect colorings of P ignoring local symmetries and considering only elements of G. A framework is presented to systematically arrive at what Roth [Geom. Dedicata (1984), 17, 99–108] defined as a coordinated coloring of P, a coloring that is perfect and transitive under G, satisfying the condition that the coloring …

The Philippines In 2018: A Year Of Disruption And Consolidation, Arjan P. Aguirre

Political Science Department Faculty Publications

2018 is a year of so much uneasiness and tension in Philippine politics. It saw one of the greatest crises in the Supreme Court, the bloodiest period in local politics of late, and successive attempts to silence critics of the president and the government. This year also witnessed major political alignments in the Duterte administration: a change in the leadership of the Senate, the election of Gloria Macapagal Arroyo as Speaker of the House, the rivalry between Hugpong ng Pagbabago and Partido Demokratiko ng Pilipinas-Lakas ng Bayan, and the eventual termination of the alliance with the radical left. This review …

A Zero-Suppressed Binary Decision Diagram Approach For Constrained Path Enumeration, Renzo Roel P. Tan, Jun Kawahara, Agnes Garciano, Immanuel Sin

Mathematics Faculty Publications

Combinatorial optimization over graphs has been the subject of research. Recently, the solution of such problems by enumeration using a compact data structure called the zero-suppressed binary decision diagram was proposed and studied. The paper augments the existing frontier-based search method of construction and puts forth a technique for accommodating additional constraints during computation. The shortest and longest path problems for the Osaka Metro transit network are simultaneously solved as demonstration. Furthermore, a comparison of the approach with a conventional integer programming method is presented towards justifying the effectiveness of the algorithm.

Fragile X- Associated Neuropsychiatric Disorders: A Case Report, Maria Melinda Tan, Jeanne Barbara Dy, Maria Jimena Salcedo-Arellano, Flora Tassone, Randi J. Hagerman

Ateneo School of Medicine and Public Health Publications

Mutations in the Fragile X Mental Retardation 1 (FMR1) gene create a spectrum of developmental disorders in children in addition to neurodegenerative problems in older populations. Two types of mutations are recognized in the FMR1 gene. The full mutation (>200 CGG repeats) in the FMR1 gene leads to Fragile X Syndrome which is the most common inherited cause of intellectual disability and autism, while the premutation (55 to 200 CGG repeats) identified among carriers leads to a range of problems linked to elevated levels of the FMR1 mRNA leading to mRNA toxicity and occasionally mildly deficient FMRP …
