The Influence of Veins on Mineral Liberation as Described by Random Masking Simulation. Minerals Engineering, 100: 109–114, January 2017.

Catchy title of research: Influence of veins on mineral liberation described by random masking simulation

The research describes the role of vein structures to better understand and interpret the origin of mineral liberation based on random masking simulation. Semicircular slabs from a copper porphyry deposit were selected and analysed in the MLA.  Classified MLA images were then subjected to image processing to identify and separate the veins from the disseminated grains. Random masking was applied on the images to simulate breakage and determine liberation of sulphides. The results provided an indication of the contribution of veins in the liberation of minerals at coarser size and the increased degree of liberation. The work also suggests cutting drill cores and using slabs for texture analysis provides more intact textural features of the ore both at micro and mesoscale thus providing a better understanding of the origin of mineral liberation.

A Two-Phase Segmentation Approach to the Impedance Tomography Problem. Inverse Problems, 33 (1): 015001, 24 pages, January 2017.

Catchy title of research: An Image Segmentation Approach to the Electrical Impedance Tomography Problem

Electrical Impedance Tomography (EIT) is a cheaper alternative imaging technique, similar to CT-scan or MRI, that uses the electrical potential and conductivity of a given body. Because of the difficulty of the problem, several approaches in solving EIT can be found in the literature. In this paper, the use of a multi-phase segmentation technique was studied in solving the EIT problem. The numerical simulations done show promising results.

Determinants of Mobile Consumers’ Perceived Value of Location-Based Advertising and User Responses. International Journal of Mobile Communications, 14 (2): 99-117, 2016.

Catchy title of research: Consumer Motivation and Responses to Location-Based Advertising

Little is known about the relationship between consumers and location-based advertising, the new and potentially high-profit frontier for the advertising industry. This study shows that privacy concerns have a stronger negative effect on perceived LBA value than perceived sacrifice, while perceived utility, utilization of contextual information and trust positively predict perceived LBA value. Moreover, perceived LBA value increases consumers’ responses to purchase advertised brands, followed by searching for brand information and passing LBA to others.
Data for this study were collected from a nationally representative web survey of 605 respondents who fit the demographic quotas of mobile consumers in Singapore. A parallel study in the Philippines can be conducted to examine cross-cultural differences in the relationship between consumers and LBAs.

Organizing and Reframing Technological Determinism. New Media & Society, 18 (8): 1528-1546, December 2016.

Catchy title of research: What is our relationship with technology?

New devices are the reason for supposedly shortening attention span of young people nowadays – a commonplace argument nowadays technological determinism (TD). However popular such arguments are, it remains that TD has been critiqued as reductionist, a historical, and simplistic.
This paper shows, however, that TD is complex and can be located across four typologies according to the axes of objective/subjective dimension and regulation/radical change sociologies, the axes of Burrell and Morgan’s Four paradigms for the analysis of social theory.
Through a survey of literature and theoretical arguments about new media and their possible consequences on political, economic, and cultural systems, the article shows how TD and social determinism constitute a continuum, rather than a dichotomy, of theories about the relationship of technology and society. It recommends the revisiting of Burrell and Morgan’s concepts and their utility in organizing other communicating theories.

Gains in child survival have been large, widespread, and in many places in the world, faster than what was anticipated based on improving levels of development. Yet some countries, particularly in sub-Saharan Africa, still had high rates of under-5 mortality in 2015. Unless these countries are able to accelerate reductions in child deaths at an extraordinary pace, their achievement of proposed SDG targets is unlikely. Improving the evidence base on drivers that might hasten the pace of progress for child survival, ranging from cost-effective intervention packages to innovative financing mechanisms, is vital to charting the pathways for ultimately ending preventable child deaths by 2030.

Fruit damage (dark holes) caused by EFSB in non-Bt eggplant fruits (Mara) compared to Bt eggplant counterpart fruits (M1) from plants in the same field block.

Eggplant is a popular vegetable grown throughout Asia. It is known to be heavily treated with insecticides to control the eggplant fruit and shoot borer (EFSB). This study is the first publicly available data on field performance in Asia of the eggplant engineered to produce the Bt Cry1Ac protein. It replicated field trials with five Bt eggplant open-pollinated (OP) lines from transformation event EE-1 and their non-Bt comparators in Pangasinan from 2010 to 2012.
The field trials documented levels of Bt protein expressed in plants and evaluated their efficacy against the primary target pest, EFSB. Cry1Ac concentrations ranged from 0.75 to 24.7 ppm dry weight with the highest in the terminal leaves (or shoots), and the lowest in the roots. Cry1Ac levels significantly increased from the vegetative to the reproductive stage. Bt eggplant lines demonstrated excellent control of EFSB. Bt eggplant lines and their non-Bt comparators were significantly different for all field efficacy parameters tested. Bt eggplant lines controlled EFSB shoot damage by 98.6–100%, and fruit damage by 98.1–99.7%. It also reduced EFSB larval infestation by 95.8–99.3% under the most severe pest pressure during Trial 2. Moths that emerged from larvae collected from Bt plants in the field and reared in their Bt eggplant hosts did not produce viable eggs or offsprings demonstrating that Bt eggplant lines provide outstanding control of EFSB and can dramatically reduce the need for conventional insecticides.

CO-Induced Pd Segregation and the Effect of Subsurface Pd on CO Adsorption on CuPd Surfaces. Journal of Physics: Condensed Matter, 29 (2): 025005, 8 pages, 18 January 2017.

In designing CuPd-based materials for hydrogen purification and storage, hydrocarbon production, and separation membranes, the interaction of CO with CuPd is an important consideration. The manner in which CO is adsorbed on the surface dictates the dynamics of movement, temperature dependence, and overall surface mobility, among others. There had also been reports that the adsorption of CO on CuPd has the tendency to modify the CuPd configuration. In this work, we performed a DFT (density functional theory) calculation using van der Waals density functional (vdW-DF2), implemented on Quantum Espresso to investigate the dynamics of the CO interaction with CuPd surface. To model comprehensively CO adsorption on CuPd we considered various surface configurations/stoichiometry such as (Cu3Pd, Cu2Pd2, CuPd3). In addition, we also investigate the Pd segregation in Cu-rich CuPd surface by considering nonstoichiometric Cu3Pd structure. Results show that the calculated adsorption sites and corresponding adsorption energies agree well with experimental findings. Among the different nonstoichiometric Cu3Pd(111), the surface with ordered structure of bulk Cu3Pd () is the energetically most stable. The adsorption of CO induces Pd segregation to surface layers due to stronger CO-Pd than CO-Cu interaction. Lastly, we found that the presence of Pd subsurface atoms enhances CO adsorption. We believe that our findings will provide helpful insights to future investigations on reactions involving CO and CuPd-based systems.

Coconut is one of the chief exports of the Philippines. Desiccated coconut is one of the food products derived from this commodity and is used in baking and confectionery. Unfortunately, cases of Salmonella contamination on exported Philippines desiccated coconut have been reported. The use of bactericidal UV (UV-C) in decontaminating Salmonella on desiccated coconut and its effect on the sensorial characteristics upon use as ingredient and in macaroon making has been explored in this study.

Fig.1. Comparison of sea level records of Paraoir, Currimao, Abrolhos Island and Tahiti.

Sea level change was reconstructed using shallow-water corals from Paraoir, western Luzon, Philippines. This was done to to document deglacial sea level rise of the western Pacific. The sea level records obtained were consistent with those of north western Luzon and the western Australia coast. Discrepancies exist with the sea level records reported for Tahiti. The difference in sea level between the Philippines and Tahiti result from spatial variations of glacial isostatic adjustment of the two sites.

Improving Predictive Accuracy of Logistic Regression Model using Ranked Set Samples. Communications in Statistics – Simulation and Computation, 46 (1): 78-90, 2017.

Catchy title of research: Ranked Set Sampling: A Tool for Better Predictive Ability of Fitted Logistic Regression Model

Many real-life scenarios produce binary data such as in health sciences when a person can be classified as “positive” or “negative” of a certain disease, in credit scoring when predicting a customer if he would pose high risk to creditors or not, and in market research wherein they are interested in determining if a consumer would choose Product A or its competitor, Product B. In these instances where the response variable is binary, Logistic Regression is most commonly used. This research proposes the use Ranked Set Sampling (RSS) in selecting observations to ensure that the predictive ability of the fitted logistic regression model is better and more reliable than using Simple Random Sampling, avoiding the occurrence of the separation of likelihood. Furthermore, the paper found that RSS also works well even when the event of interest is rare in the population.

Hydrologic Impact Evaluation of Land Use and Land Cover Change in Palico Watershed, Batangas, Philippines Using the SWAT Model. Journal of Environmental Science and Management, 19 (1): 96-107, June 2016. 

Catchy title of research: Effect of Land Use and Land Cover Change on Streamflow in Palico Watershed, Batangas, Philippines

Figure 1. The Palico Watershed Located in southern Luzon,
Philippines along the Verde Island Passage
Corridor.

This study was conducted to evaluate the impact of land use and land cover (LULC) change on the streamflow of Palico watershed in Batangas, Philippines using a mathematical model known as the Soil and Water Assessment Tool (SWAT) model. Results showed that reduction in forest cover and rangeland leads to increase in surface runoff and decreases in baseflow or dry season flow and groundwater recharge. LULC change affects the water quantity and timing of occurrence. Subbasin with 22% increase in both forest cover and rangeland increased the baseflow by 1% to 15% and reduced the streamflow by 1% to 17% during the rainy months. Another subbasin with 54% forest loss resulted to more pronounced rainfall-runoff response with 11% to 17% decrease in baseflow and 4% to 24% increase in streamflow during rainy months.  Results of this study may be used for devising sustainable watershed management schemes.

Effects of Consumption of Tilapia (Oreochromis niloticus) and Walking Catfish (Clarias batrachus) from Laguna de Bay On the Uterus of Ovariectomized ICR Mouse. Philippine Journal of Veterinary Medicine, 53 (1): 34-43, 2016.

Catchy title of research: Consumption of Tilapia and Walking Catfish from Laguna de Bay led to Changes in the Uterus of Ovariectomized Mouse

The effect of consumptionof tilapiaand walking catfish from Laguna de Bay was studied using female ICR mice. Ninety-five 6-week old ovariectomized mice were randomly distributed into the following groups: 1) distilled water (negative control); 2) 1% homogenized catfish meat; 3) 3% homogenized catfish meat; 4) 1% homogenized tilapia meat; 5) 3% homogenized tilapia meat; 6) 1% homogenized catfish roe; and 7) 1% homogenized tilapia roe. Treatment was given via stomach tube three times a week for 28 days. Tilapia meat (3%) and catfish roe (1%) significantly increased both uterine wet and relative weights whereas tilapia roe (1%) only increased uterine wet weight. Groups given the tilapia (3%) and catfish meat (3%) had greater uterine epithelial and myometrial thickness, respectively. Weight gain, feed consumption and uterine width were unaffected by the treatments. The results are suggestive of fish contamination with estrogenic chemicals in the lake. The observed estrogenic effects brought about by the consumption of contaminated fish could have potential health implications.

Myth and The Poetics of the Self: The Critical Corpus of Gémino H. Abad. Kritika Kultura, 26: 762-771, 2016.

The article unpacks the prolific body of critical writings of eminent Filipino writer and scholar Gemino H. Abad by identifying the humanist and romantic theories of poetic subjectivity that underlie them. It reconsiders the postfoundational critique of essentialist notions of the self through the prism of mythopoesis, and argues that in the case of Abad at least, the persistent championing of the sovereign imagination is historically explainable as necessary, precisely because it provides the impetus for the continued interrogation of literary and creative practices from the perspective of their interested natures as social constructions on one hand, and of the mythmaking imperative on the other, through which minoritized voices may be able to promote their own respective sociopolitical causes.

Global, Regional, and National Life Expectancy, All-Cause Mortality, and Cause-Specific Mortality for 249 Causes of Death, 1980–2015: A Systematic Analysis for the Global Burden of Disease Study 2015. Lancet, 388 (10053): 1459–1544, 8 October 2016.

Figure 1
Estimation of all-cause mortality by age and sex and HIV/AIDS incidence, prevalence, and mortality for GBD 2015.

Globally, the average life expectancy has risen from 61.7 years in 1980 to 71.8 years in 2015. These gains were largely attributed to reductions in HIV/AIDS and malaria deaths, as well as to reductions in neonatal birth complications and maternal disorders. Although global trends generally show reduced death rates from injuries, war and interpersonal conflict are taking more lives in certain regions like the Middle East. Currently, about 70% of deaths are now caused by non-communicable diseases. This is a category that includes basically any illness that is not infectious, such as heart disease, stroke, or diabetes. The fact that these outcomes have large lifestyle components is not a coincidence, especially since high blood pressure, smoking, and obesity were leading risk factors for early death or illness in 2015. When looking for causes of ill health—rather than death—the leading causes were lower back and neck pain, sight and/or hearing loss, depression, and iron deficiency. Consequences of drug use, especially cocaine or opioids, are also large contributors. On the plus side, levels of chronic obstructive pulmonary disease, cervical cancer, ischemic heart disease, and asthma are showing drops.

Figure 2
Map of health-related SDG index, by quintile, 2015.

The current study marks the first annual assessment of SDG health performance and will be launched at the UN General Assembly in New York on September 21. The Lancet's report shows that, overall, good progress has been made toward health-related SDGs. For instance, under-5 neonatal mortality, universal healthcare, and family planning have all shown improvement. On the other side of the coin, some areas beyond the MDGs have not shown such improvements. Areas such as hepatitis B rates, childhood overweight, intimate partner violence, and rates of harmful alcohol consumption have worsened. As the MDG era comes to a close, The Lancet's report aims to provide a tool for global accountability as we head toward the 2030 SDG targets. With some solid numbers in place, governments, aid organizations, and other official bodies will be better able to identify the wins and the gaps, allowing them to prioritize intelligently.

“The Greatest Workers of the World”: Philippine Labor Out-Migration and the Politics of Labeling in Gloria Macapagal-Arroyo’s Presidential Rhetoric. Philippine Political Science Journal, 37 (3): 207-227, 2016.

This paper initiates a critical analysis of the State of the Nation Addresses (SONA) and occasional speeches through which the presidency of Gloria Macapagal-Arroyo constructed figures of overseas Filipino workers (OFWs). First, it connects the former Philippine head of state’s banner vision of a “Strong Republic” to labor out-migration. Second, it surveys the labels Macapagal-Arroyo tapped to refer to or categorize migrant workers. And finally, it problematizes the politics behind state labeling and its participation in migrant discourses within and beyond the Philippine nation. Results show that Arroyo hailed migrant workers as the country’s “greatest export,” as its “investors, proprietors, stakeholders, and philanthropists,” and as its “full partners in developmental, demographic and democratic transformation.” By calling OFWs names based on market economies, the former president tried to rhetorically transform migrant identities and subjectivities usually immersed in sacrifice, hardship, and pity into something more appealing for the “modern” and “global” status to which the Philippine nation-state aspires. In this light, rhetorical enterprises such as presidential speeches may be seen as a crucial communicative technology of a political institution that perpetrates practices of control toward its exported human labor, and that employs discursive apparatuses to manage labor exportation.

Probiotics use has a very good potential in mitigating the global problem on antibiotic resistance.  Multiple studies have confirmed the beneficial effects of probiotic use in the health of both livestock and humans.  The use of probiotics in lieu of antibiotic therapy to address certain health conditions in both animals and humans may alleviate these antibiotic-mediated selective pressures which hasten the development of antibiotic resistance.  However, without proper regulation, probiotic strains are also capable in spreading antibiotic resistance genes.  As such, we underscore the need to screen probiotic strains that are used in both livestock and human applications to assure their safety and to mitigate their potential in significantly contributing to the spread of antibiotic resistance genes in our natural environments.

Aedes Dengue Vector Ovitrap Surveillance System: A Framework for Mosquito Density Prediction. Southeast Asian Journal Of Tropical Medicine And Public Health, 47 (4): 712-718, July 2016.

The Philippine Ovitrap Kit (De Las Llagas).

The Ovitrap Surveillance System Framework (De Las Llagas 2002, 2007, 2009, 2013, 2014).

Dengue has been a major global public health problem. The rising dengue cases especially among children makes it all the more imperative to find new methods to counter this vector-borne disease. Vector surveillance is a key component in prevention and control program for vector-borne diseases. Vector surveillance, when not done actively and regularly, can be unreliable as means of preventing dengue transmission. Meanwhile, implementing a successful vector control program calls for the understanding of the different factors that regulate mosquito population as well as mosquito reaction to control measures.
As of date, there is no single available instrument to monitor the mosquito population as means to predict dengue transmission and spread. 
Thus, the researchers proposes a framework for mosquito density prediction that would enable a clearer understanding of the advantages and merits of using the ovitrap system and its measurement, the ovitrap index (OI). The framework is empirically derived from past researches and is an integration of variables depicting the interrelationships of mosquito population growth and development. These interrelated indicators include the climate such as temperature and relative humidity; the ecologoical-sociological vector control such as the presence of containers; and the cycle of mosquito development.
These components, logically integrated into a framework, potentially arrives at a prediction of mosquito density. With recognition, the framework opens up the possibility of determining the risk of dengue transmission without having to do active surveillance.
