TL;DR: Despite heavy infection with intestinal parasites, and marked hepatic tissue damage owing to severe capillariasis and strobilocercus larval infection, all rats appeared healthy and agile, suggestive of a well-established rat host-parasite relationship.
Abstract: Rattus spp trapped in wet markets in Quiapo, Manila and Balayan, Batangas had ectoparasites, Echinolaelaps echidnius (mite), and Polyplax spinulosa (louse). The endoparasites identified were Hymenolepis diminuta; the acanthocephalan Moniliformis moniliformis; Taenia taeniaeformis strobilocercus larvae and Capillaria hepatica in liver; Trichosomoides crassicauda of the urinary bladder; Sarcocystis sp of muscle tissue; and two different species of stronglyloid-looking intestinal nematodes. Rats had 100% infection with C. hepatica and T. taeniaeformis, exhibiting high parasitemia. The co-existence of rats with diverse parasitic species is reflective of the host's capability to support parasites' behavioral, physiological, and developmental needs. Despite heavy infection with intestinal parasites, and marked hepatic tissue damage owing to severe capillariasis and strobilocercus larval infection, all rats appeared healthy and agile, suggestive of a well-established rat host-parasite relationship. In view of the diversity and zoonotic nature of rat parasites, and the impoverished conditions prevailing in communities where Rattus spp survive and proliferate, they can readily facilitate parasite transmission to humans and other susceptible animal hosts.

TL;DR: Topical quinolone antibiotics can clear aural discharge better than no drug treatment or topical antiseptics; non-quinolone antibiotic effects (without steroids) versus no drug or antisePTics are less clear.
Abstract: Background
Chronic suppurative otitis media (CSOM) causes ear discharge and impairs hearing.
Objectives
Assess topical antibiotics (excluding steroids) for treating chronically discharging ears with underlying eardrum perforations (CSOM).
Search methods
The Cochrane Ear, Nose and Throat Disorders Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library Issue 1, 2005), MEDLINE (January 1951 to March 2005), EMBASE (January 1974 to March 2005), LILACS (January 1982 to March 2005), AMED (1985 to March 2005), CINAHL (January 1982 to March 2005), OLDMEDLINE (January 1958 to December 1965), PREMEDLINE, metaRegister of Controlled Trials (mRCT), and article references.
Selection criteria
Randomised controlled trials; any topical antibiotic without steroids, versus no drug treatment, aural toilet, topical antiseptics, or other topical antibiotics excluding steroids; participants with CSOM.
Data collection and analysis
One author assessed eligibility and quality, extracted data, entered data onto RevMan; two authors inputted where there was ambiguity. We contacted investigators for clarifications.
Main results
Fourteen trials (1,724 analysed participants or ears). CSOM definitions and severity varied; some included otitis externa, mastoid cavity infections and other diagnoses. Methodological quality varied; generally poorly reported, follow-up usually short, handling of bilateral disease inconsistent. Topical quinolone antibiotics were better than no drug treatment at clearing discharge at one week: relative risk (RR) was 0.45 (95% confidence interval (CI) 0.34 to 0.59) (two trials, N = 197). No statistically significant difference was found between quinolone and non-quinolone antibiotics (without steroids) at weeks one or three: pooled RR were 0.89 (95% CI 0.59 to 1.32) (three trials, N = 402), and 0.97 (0.54 to 1.72) (two trials, N = 77), respectively. A positive trend in favour of quinolones seen at two weeks was largely due to one trial and not significant after accounting for heterogeneity: pooled RR 0.65 (0.46 to 0.92) (four trials, N = 276) using the fixed-effect model, and 0.64 (95% CI 0.35 to 1.17) accounting for heterogeneity with the random-effects model. Topical quinolones were significantly better at curing CSOM than antiseptics: RR 0.52 (95% CI 0.41 to 0.67) at one week (three trials, N = 263), and 0.58 (0.47 to 0.72) at two to four weeks (four trials, N = 519). Meanwhile, non-quinolone antibiotics (without steroids) compared to antiseptics were more mixed, changing over time (four trials, N = 254). Evidence regarding safety was generally weak.
Authors' conclusions
Topical quinolone antibiotics can clear aural discharge better than no drug treatment or topical antiseptics; non-quinolone antibiotic effects (without steroids) versus no drug or antiseptics are less clear. Studies were also inconclusive regarding any differences between quinolone and non-quinolone antibiotics, although indirect comparisons suggest a benefit of topical quinolones cannot be ruled out. Further trials should clarify non-quinolone antibiotic effects, assess longer-term outcomes (for resolution, healing, hearing, or complications) and include further safety assessments, particularly to clarify the risks of ototoxicity and whether quinolones may result in fewer adverse events than other topical treatments.

TL;DR: Results showed that the bilingual students were more successful in understanding and solving word problems that were stated in their first language, and were more likely to experience failure in finding a solution to problems stating in their second language.
Abstract: Researchers have suggested that among bilinguals, solving word problems in mathematics is influenced by linguistic factors (K. Durkin & B. Shire, 1991; L. Verschaffel, B. Greer, & E. De Corte, 2000). Others have suggested that students exhibit a strong tendency to exclude real-world constraints in solving mathematics word problems (L. Verschaffel, E. De Corte, & S. Lasure, 1994). In the present study, the authors explored the effects of stating word problems in either Filipino or English on how Filipino-English bilingual students solved word problems in which the solution required the application of real-world knowledge. The authors asked bilingual students to solve word problems in either their first or second language. For some of the word problems, real-life constraints prevented straightforward application of mathematical procedures. The authors analyzed the students' solutions to determine whether the language of the word problems affected the tendency to apply real-life constraints in the solution. Results showed that the bilingual students (a) rarely considered real-life constraints in their solutions, (b) were more successful in understanding and solving word problems that were stated in their first language, and (c) were more likely to experience failure in finding a solution to problems stated in their second language. The results are discussed in terms of the relationship between linguistic and mathematical problem-solving processes among bilinguals.

TL;DR: In this paper, the authors argue that self-determination rights can be adequately exercised by people who have clearly defined their national identity and concept of a nation, but the Moro multi-ethnic national identity has yet to be crystallised while the idea of a Bangsamoro (Bangsa nation) remains weak.
Abstract: The continuing struggle of the Moro secessionist movement in the Philippines is one of Southeast Asia's longest armed conflicts. The tenacity of the conflict lies in two competing concerns: the assertion of self‐determination rights of the Moro separatist movement; and the affirmation of the Philippines’ sovereign right to territorial integrity. However, beneath these rights are crucial issues that remain unanswered both by the contending forces—problems where internecine violence and conflict emanate from. This article argues that self‐determination rights can be adequately exercised by people who have clearly defined their national identity and concept of a nation. Unfortunately, the Moro multi‐ethnic national identity has yet to be crystallised while the idea of a Bangsamoro (Bangsa Nation) remains weak. On the other hand, the state has yet to address the Moron’ legitimate demands of political autonomy, socio‐economic development, and social justice and discrimination. Without underestimating the ethni...

TL;DR: The results showed that both species can recruit and inhabit a similar coastal zone when appropriate strategies are expressed to minimize damage in response to the stress factor.
Abstract: Young sporophytes of Saccorhiza dermatodea and Alaria esculenta cultured from Spitsbergen isolates were exposed in the laboratory to either only photosynthetically active radiation (PAR) or to a spectrum including UV-radiation (PAR+UVA+UVB) by use of cutoff glass filters. The plants were grown at 8±2°C and 16:8 h light–dark cycles with 6 h additional UV exposure in the middle of the light period. Growth was measured every 10 min using growth chambers with online video measuring technique for 18–21 days. Tissue morphology and absorption spectra were measured in untreated young sporophytes while tissue chlorophyll-a content and DNA damage were measured from treated thalli at the end of the experiment. Under UVR, growth rates of S. dermatodea were significantly reduced while A. esculenta have a potential to acclimate. Tissue chlorophyll-a contents in both species were not significantly different between treatments suggesting that these algae may acclimate to moderate UVR fluence. Higher DNA damage in S. dermatodea effectively diverted photosynthetic products for repair constraining growth. Tissue optics (opacity and translucence) was correlated to the tissue absorbance in the UVR region characteristics of phlorotannin, an important UV-absorbing compound in brown macroalgae. Growth rates of sporophytes of both species exposed to PAR without UV was similar during day and night. The results showed that both species can recruit and inhabit a similar coastal zone when appropriate strategies are expressed to minimize damage in response to the stress factor.

TL;DR: This paper presents an alternative streamlined approach wherein heuristic rules are derived from a set of training data in the form of example alternatives ranked in order of preference by the expert, and lead to a decision consistent with the expert preferences embodied in the training data.
Abstract: Life cycle assessment (LCA) is a methodology for assessing environmental burdens of products or processes on a cradle-to-grave basis. The impact assessment phase necessitates use of decision analysis methods to account for multiple environmental criteria in the comparison of technological alternatives. Valuation or weighting of the impact criteria is usually accomplished by eliciting relative or absolute scores from an expert. This paper presents an alternative streamlined approach wherein heuristic rules are derived from a set of training data in the form of example alternatives ranked in order of preference by the expert. These decision rules are generated using an induction process based on rough set theory. The heuristic rules can subsequently be used to compare and rank new alternatives, and lead to a decision consistent with the expert preferences embodied in the training data.

TL;DR: In this paper, a photoconductive antenna fabricated on a single crystal zinc oxide (ZnO) is presented, where the power of the ZnO is saturated at bias voltages above 800V∕cm and the obtained spectrum extends up to 1 THz.
Abstract: Terahertz (THz) radiation generated from photoconductive antenna fabricated on a single crystal zinc oxide (ZnO) is presented. The THz-radiation power is saturated at bias voltages above 800V∕cm and the obtained spectrum extends up to 1 THz. Moreover, ZnO is found to be highly transparent in the visible, near-infrared, mid-infrared and THz frequency regions. The results depicted here will categorically unravel the prospects of using ZnO as a material for integrated active optics.

TL;DR: A system that is developed that performs automatic size and defect recording, and then consolidates schedules and defect lists of individual developers into a schedule and defect library for the developers' team.
Abstract: The personal software process (PSP) is a process and performance improvement method aimed at individual software engineers. The use of PSP has been shown to result in benefits such as improved estimation accuracy and reduced defect density of individuals. However, the experience of our institute and of several others is that recording various size and defect data can be onerous, which in, turn can lead to adoption and data quality problems. This paper describes a system that we have developed that performs automatic size and defect recording, aside from providing facilities for viewing and editing the usual PSP logs and reports. Moreover, the system automatically classifies and ranks defects, and then consolidates schedules and defect lists of individual developers into a schedule and defect library for the developers' team.
TL;DR: An alternative approach making use of Zimmermann's symmetric fuzzy linear programming method is proposed and illustrated with a simple case study, which effectively yields a single, optimal compromise solution in LCA.
Abstract: Life cycle assessment (LCA) is known to entail multiple objective decision-making in the analysis of tradeoffs between different environmental impacts. The work of Azapagic and Clift in the late 1990s illustrates the use of multiple objective linear programming (MOLP) in the context of LCA. However, it will be noted that their approach yields a range of Pareto optimal alternatives from which the decision-maker must ultimately select the final solution. An alternative approach making use of Zimmermann's symmetric fuzzy linear programming method is proposed and illustrated with a simple case study. The procedure effectively yields a single, optimal compromise solution.
TL;DR: The results of the present study showed that linguistic factors do not affect the more mathematically abstract components of word problem solving, although they may affect the other components such as those related to reading comprehension and understanding.
Abstract: The study was conducted to determine whether the language of math word problems would affect how Filipino-English bilingual problem solvers would model the structure of these word problems. Modeling the problem structure was studied using the problem-completion paradigm, which involves presenting problems without the question. The paradigm assumes that problem solvers can infer the appropriate question of a word problem if they correctly grasp its problem structure. Arithmetic word problems in Filipino and English were given to bilingual students, some of whom had Filipino as a first language and others who had English as a first language. The problem-completion data and solution data showed similar results. The language of the problem had no effect on problem-structure modeling. The results were discussed in relation to a more circumscribed view about the role of language in word problem solving among bilinguals. In particular, the results of the present study showed that linguistic factors do not affect the more mathematically abstract components of word problem solving, although they may affect the other components such as those related to reading comprehension and understanding.
TL;DR: In this paper, implicit trait and contextual theories encompass lay people's beliefs about the longitudinal stability (vs. instability) of traits; the cross-situational consistency (vs variability) of behavior; the ability to predict (vs not predict) individuals' behavior from their traits; and the importance of traits in understanding people.
Abstract: Implicit trait and contextual theories encompass lay people’s beliefs about the longitudinal stability (vs. instability) of traits; the cross-situational consistency (vs. variability) of behavior; the ability to predict (vs. not predict) individuals’ behavior from their traits; the ability to infer traits from few behavioral instances (vs. the difficulty of doing so); and the importance of traits in understanding people (vs. the greater importance of contextual factors such as roles and relationships). Implicit trait and contextual beliefs were investigated in two individualistic cultures, the United States and Australia, and two collectivistic cultures, Mexico and the Philippines. Hypotheses based on an integration of trait and cultural psychology perspectives were supported. The structure of implicit beliefs replicated well, and trait beliefs predicted judgments about cross-situational consistency of behavior in all four cultures. Implicit trait beliefs were stronger, and implicit contextual beliefs wea...

TL;DR: This work proposes a methodical and automatic SOM labeling procedure that does not require a set of prelabeled patterns and instead, nodes in the trained map are clustered and subsets of training patterns associated to each of the clustered nodes are identified.
Abstract: Learning in self-organizing maps (SOM) is considered unsupervised because training patterns do not need accompanying desired output information. Prior to its use in some real-world applications, however, a trained SOM often has to be labeled. This labeling phase is usually supervised in that labeled patterns need accompanying output information. Because such labeled patterns are not always available or may not even be possible to construct, the supervised nature of the labeling phase restricts the deployment of SOM from a wide range of potential domains of application. This work proposes a methodical and automatic SOM labeling procedure that does not require a set of prelabeled patterns. Instead, nodes in the trained map are clustered and subsets of training patterns associated to each of the clustered nodes are identified. Salient dimensions per node cluster that constitute the bases for labeling each node in the map are then identified. The effectiveness of the method is demonstrated on a SOM-based international market segmentation study.

TL;DR: The leaves of Lagerstroemia speciosa afforded a new natural product, 31-norlargerenol acetate, along with known compounds 24-methylenecycloartanol acetate and tinotufolins C, which was elucidated by 1D and 2D NMR and mass spectroscopy.
TL;DR: In this paper, the authors use a detailed economywide computable general equilibrium (CGE) model to run a series of policy experiments to find that poverty increases slightly with the implementation of the prospective Doha scenario.
Abstract: Since the early 1980s the Philippines has undertaken substantial trade reform. The current Doha Round of World Trade Organization (WTO) negotiations is now likely to bring further reform and shocks to world import prices and export demand. The impact of all these developments on the poor is not very clear and is the subject of intense debate. The authors use a detailed economywide computable general equilibrium (CGE) model to run a series of policy experiments. They find that poverty increases slightly with the implementation of the prospective Doha scenario. These effects are focused primarily among rural households in the wake of falling world prices and demand for the Philippines' agricultural exports. The authors find that the impacts of full liberalization-involving free world trade and complete domestic liberalization-depend strongly on the mechanism the government adopts to offset forgone tariff revenue. If an indirect tax is used, the incidence of poverty falls marginally, but the depth (poverty gap) and severity (squared poverty gap) increase substantially. If, instead, an income tax is used, all measures of poverty increase. In both cases, full liberalization favors urban households, as exports, which are primarily nonagricultural, expand. In separate simulations, the authors discover that free world trade is poverty reducing and favors rural households, whereas domestic liberalization is poverty increasing and favors urban households. Under free world trade, rural households benefit from increasing world agricultural demand. The anti-rural bias of domestic liberalization stems from the fact that import prices fall more for agricultural goods than for industrial goods, as initial import-weighted average tariff rates are higher for the former. In conclusion, the current Doha agreement appears likely to slightly increase poverty, especially in rural areas and among the unemployed, self-employed, and rural low-educated. The Philippines is found to have an interest in pushing for more ambitious world trade liberalization, as free world trade holds out promise for reducing poverty.
TL;DR: In this paper, the electronic and magnetic properties of single-walled carbon nanotubes (SWNTs) filled with Fe nanowires, based on the spin-polarized density functional theory, were investigated.
Abstract: We investigate the electronic and magnetic properties of single-walled carbon nanotubes (SWNTs) filled with Fe nanowires, based on the spin-polarized density functional theory. We find that in the stable structure, the Fe-filled (3,3) and (5,0) SWNTs exhibit semiconducting properties, and the magnetic moment of Fe nanowires inside disappears. On the other hand, the Fe-filled (4,4), (5,5), (6,6) and (6,0) SWNTs, having larger radii, are metallic and exhibit ferromagnetic properties. The corresponding magnetic moment increases with increasing nanotube diameter.
TL;DR: In this article, the authors carried out density functional theory-based calculations to investigate the dissociative adsorption on two platinum surfaces, viz., Pt(111) and Pt(001), and calculated the corresponding total energies, for varying center-of-mass distances from the Pt surface, and varying O-O interatomic distances.
Abstract: We carry out density functional theory-based calculations to investigate the oxygen $({\mathrm{O}}_{2})$ dissociative adsorption on two platinum (Pt) surfaces, viz., Pt(111) and Pt(001). We calculated the corresponding total energies, for varying ${\mathrm{O}}_{2}$ center-of-mass distances from the Pt surface, and varying O-O interatomic distances. Our calculation results show that the ${\mathrm{O}}_{2}$ dissociative adsorption progresses much more easily on Pt(001) than on Pt(111). These results are in good agreement with experimentally observed differences and trends in reactivities of Pt(001) and Pt(111).
TL;DR: In this paper, the authors reported results of a study on the interaction of hydrogen with thin Au films grown on an Ir surface at the cost of increasing the binding energy and activation barrier for desorption via lattice relaxation of the Au layer.
Abstract: We report results of a study on the interaction of hydrogen with thin Au films grown on an Ir{111} surface at $\ensuremath{\approx}100\phantom{\rule{0.3em}{0ex}}\mathrm{K}$, using nuclear reaction analysis and first-principles calculations. We found that H atoms can be confined at the interface between the bulk-Ir surface and the Au thin film, which is realized by increasing the binding energy and the activation barrier for desorption via lattice relaxation of the Au layer.
TL;DR: In this article, the electric and magnetic properties of a (3,3) single-walled carbon nanotube filled with a linear Co nanowire were investigated based on spin-polarized density functional theory.
Abstract: We investigate the electric and magnetic properties of a (3,3) single-walled carbon nanotube filled with a linear Co nanowire. We carry out first-principle calculations based on the spin-polarized density functional theory, and find that in the stable structure, it shows half metallic ferromagnetic behavior, i.e., the majority-spin electrons show metallic behavior while the minority-spin electrons have a semiconducting bandgap.
TL;DR: In this article, the authors reported results of their studies on the dissociative adsorption of hydrogen on Au thin films grown epitaxially on Ir{1,1, 1} surface, using nuclear reaction analysis.
TL;DR: In this paper, the potential energy surfaces (PESs) and potential energy curves (PECs) for H 2 at symmetric sites on a Li(100) surface within the density functional theory were investigated.
Abstract: We investigate the interaction of molecular/atomic hydrogen with the Li surface. We calculate the potential energy surfaces (PESs) for H 2 and the potential energy curves (PECs) for H at symmetric sites on a Li(100) surface within the density functional theory. The PESs results show the dependence of the energy barriers for H 2 dissociative adsorption and the stable adsorption sites for the dissociated H atoms on the H 2 center-of-mass (CM) position and the H 2 orientation relative to the surface. Also, reaction paths for the direct absorption of H 2 can be seen when the H 2 CM is directly above the bridge site of the Li(100) surface. Meanwhile, the PECs results indicate that the energy barriers for H absorption and the stable H adsorption sites depend on the H lateral position relative to the surface. A very low energy barrier was observed for H absorption on the bridge site of the surface. Finally, we present a practical explanation of the PESs' and PECs' dependence on the H 2 position and orientation r...
TL;DR: In this article, the authors proposed a model to explain the unexpected high reactivity of the thin Au{1, 1, 1} surface, where narrowing of the s-band is responsible.
Abstract: Dissociative adsorption of H 2 (D 2 ) on Au thin films grown on an Ir{1 1 1} surface has been studied with temperature-programmed desorption using a quadrupole mass spectrometer and nuclear reaction analysis. Thin Au{1 1 1} films are epitaxially grown on Ir{1 1 1}, as confirmed by low-energy electron diffraction and scanning tunneling microscopy. H 2 (D 2 ) was dissociatively adsorbed on these Au{1 1 1} films, although it is well known that Au surfaces are noble enough not to dissociate hydrogen molecules. We propose a model to explain the unexpected high reactivity of the thin Au{1 1 1} surface, where narrowing of the s-band is responsible. Moreover, we found that H (D) atoms can be confined into the interface between the Ir surface and the Au thin film. We demonstrate how reactive Au thin films grown on an Ir surface are, and also compare the Au films with Ag films grown on Ir in order to test the validity/generality of our proposed model.

TL;DR: In this article, a reactive ion etching (RIE) process was proposed for NiFe thin-film etching, considering the interaction between the magnetic metal surface NiFe and various gases.
Abstract: We propose a reactive ion etching (RIE) process design from first-principles calculations for implementation to NiFe thin-film etching. We consider the interaction between the magnetic metal surface NiFe and various gases. We found that the gases CO/NH3, or CH3OH/O2(/NH3,H2) enable the NiFe surface to be etched.
