The Ateneo de Davao University is a private teaching, service and research university run by the Society of Jesus in Davao City in the Philippines. It is also known by the acronym AdDU. It was established in 1948, and is the seventh Ateneo opened by the Jesuits in the Philippines. The university has five undergraduate schools, namely the School of Arts and science, School of Business and Governance, School of Engineering and Architecture, School of Education and the School of Nursing. The graduate programs are under these units as well. The College of Law is a separate unit within the university. The university also runs a grade school and high school.The University was granted "Institutional Accreditation" by the Philippine Accrediting Association of Schools, Colleges and Universities in which only six universities in the country were given such recognition, and was also granted Autonomous Status by the Commission on Higher Education . In terms of university rankings, Ateneo de Davao University placed 201st in years 2009 and 2010 and belonged to the 301+ bracket and 251-300 bracket in 2012 and 2014 respectively according to the rankings done by Quacquarelli Symonds on top universities in Asia. Also, the Ateneo de Davao joined the roster of world universities in the 2012 QS World University Subject Ranking for English Language and Literature joining Oxford and Harvard, wherein it landed on the 101-150 bracket.In the national rankings done by the Commission on Higher Education and the Professional Regulation Commission based on cumulative data from 1991 to 2001 of average passing rates in all courses of all Philippine colleges and universities in licensure examinations, Ateneo de Davao University was proclaimed as the 5th top university in the country. Locally, AdDU emerged as the top school in Davao City according to the ranking published by Davao Reader and also in another ranking by Davao Eagle Online which was based on the number of PRC board topnotchers in 2013.

A transient micellar phase extractor using CTAB was described for the online sample concentration of various anionic analytes (drugs and herbicides) in CE. Stacking and separation was performed at neutral pH in coelectroosmotic flow in a hexadimethrine bromide coated fused-silica capillary. A micellar plug (e.g. 10 mM CTAB) was injected prior to hydrodynamic injection of the analytes prepared in aqueous organic solvent (e.g. with 30% ACN). In the presence of an electric field, the micelles interacted with the anions inside the capillary. This was followed by selective analyte focusing via the mechanism of micelle to solvent stacking. The micelles acted as transient extractor because the stacking ends when the injected micelles completely migrated through the boundary between the sample and micellar plug. Fundamental studies were performed (effect of surfactant concentration, etc.) and the technique yielded 13-to 30-fold improvements in peak height. A stacking CE method in conjunction with liquid-liquid extraction was also tested for the detection of the herbicides fenoprop and mecoprop in fortified drinking water at analyte concentration levels relevant to Australian Drinking Water Guidelines. © 2012 WILEY-VCH Verlag GmbH & Co.

Injection of a sodium dodecyl sulfate micellar plug prior to the sample solution induced transient micellar phase extraction of cationic drugs in capillary electrophoresis. Micelle to solvent stacking mechanism was utilized by preparing the sample in aqueous organic solvent. Synergism was achieved with field enhanced sample injection that allowed larger sample loads. Micelle to solvent stacking occurred concurrently with the enhanced injection after the fast moving analytes electrophoretically migrated into the micellar plug. This was different from stacking combinations with field enhancement where the electric field strength difference was involved in analyte focusing. Using a sample diluent that had one-tenth the conductivity of the background solution, the strategy afforded thousands-fold improvements in peak height and LODs (S/. N= 3) of as low as 1.1. ng/mL. The results were repeatable and linear. Adaptability to real sample analysis was evaluated using spiked urine sample after minimal sample clean-up. © 2012.

Objective: To investigate the antimicrobial properties of Ficus pseudopalma (F. pseudopalma) leaf extracts. Methods: The antibacterial properties of F. pseudopalma Blanco crude ethanolic leaf extract, and its solvent fractions chloroform (CF), ethylacetate (EF) and water fractions were evaluated through antibacterial agar disc diffusion method and the minimum inhibitory concentration (MIC) was determined. Five Gram-positive and five Gram-negative bacteria were used for the study. Results: The zone of inhibitions obtained from the antibacterial agar diffusion disc method showed that CF, and EF exhibited active (14-19 mm) antibacterial activity against Bacillus subtilis UST CMS 1011, and partially active (10-13 mm) antibacterial properties against both Staphylococcus aureus ATCC 25923 and Staphylococcus epidermidis ATCC 12228. Water exhibited no antibacterial properties against all microorgranisms tested. The MIC values observed for all Gram-positive bacteria tested were >5 mg/mL, except for Bacillus subtilis whose MIC value was 5 mg/mL for CF and EF fractions. All extracts exhibited no antibacterial activity against Gram-negative bacteria. Conclusions: From this study, it can be concluded that F. pseudopalma extracts may be a potential antibacterial agent against Gram-positive bacteria. The antibacterial property may be attributed to flavonoids and terpenoids present in the crude ethanolic extract, CF and EF. © 2014 Asian Pacific Tropical Medicine Press.

This study examines the effects of institutions emanating from the social environment on ecologically sustainable consumer behaviour in a developing country context. Drawing on the behavioural perspective model of consumer choice and institutional theory, this study argues that the regulative, normative and cognitive dimensions of the institutional environment play critical roles in shaping the pro-environmental attitudes called eco-attitudes of consumers. In turn, eco-attitudes positively influence the eco-behaviour of consumers. The structural equation modelling of data from a survey of 1045 consumers from the Philippines shows the significant and positive effects of the regulatory, normative and cognitive dimensions of the institutional environment on the eco-attitudes of consumers, which in turn have strong positive influence on eco-behaviour. The findings about the partial mediating role of eco-attitudes offer a more nuanced explanation on how institutions explain the eco-behaviour of consumers which is a topic that is less understood especially in a developing country context. The study highlights the theoretical, methodological, policy and future research implications of the findings. © 2015 John Wiley & Sons Ltd.

In this paper, by injecting a SDS micellar plug before the sample prepared in aqueous organic solvents, we show the on-line sample preconcentration of cations via micelle to solvent stacking (MSS) using solvents of as low as 30%. This extends the choice of stacking techniques to include moderate amounts of organic solvent in the sample. The approach is akin to in-line solid phase extraction where the micellar plug acted as a transient micellar phase extractor. Basic studies were conducted (e.g. type and amount of organic solvent in the sample). The calculated sensitivity enhancement factors based on LOD obtained for the six test antipsychotic drugs were from 41 to 68. The peak signals were linear (R2 > 0.99) from 0.2 to 10.0 μg/mL. The intraday and interday reproducibility (n = 10) for migration time, peak height, and corrected peak area were from 0.2 to 13.6%. The technique was also tested on spiked wastewater sample with minimal sample treatment (i.e. dilution and centrifugation). © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
