Circular Economy on Construction and Demolition Waste: A Literature Review on Material Recovery and Production.

Construction and demolition waste (CDW) accounts for at least 30% of the total solid waste produced around the world. At around 924 million tons in the European Union in 2016 and 2.36 billion tons in China in 2018, the amount is expected to increase over the next few years.

Nutrient concentration in sediments accumulated in pre-treatment basins of urban LID technologies.

In this study, the contribution of pre-treatment basins of low impact development (LID) technologies to nutrient reduction performance was evaluated by understanding the distribution of nutrient in sediments accumulated in each system. The captured sediments were mostly silt to medium sand ranging from 9% to 92% of the sediments collected. Greater average N and P concentrations were found in silt particles amounting to 345 mg/kg and 696 mg/kg, respectively compared to sand and gravel.

An AHP-based evaluation method for teacher training workshop on information and communication technology.

The emergence of information and communication technology (ICT) has created opportunities for enhancing the learning process at different educational levels. However, its potential benefits can only be fully realized if teachers are properly trained to utilize such tools. The rapid evolution of ICT also necessitates rigorous assessment of training programs by participants.

PTSD factor structure and relationship with self-construal among internally displaced persons.

The present study examined the factor structure of six competing posttraumatic stress disorder (PTSD) models based on the recent changes in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) in a sample that, while highly vulnerable to PTSD, very few studies have focused on-Asians, particularly Filipino internally displaced persons (IDPs). In recognition of the role of culture in PTSD factor structure, we also investigated the associations of the factors of the best-fitting model with self-construal. A sample of 460 IDPs in government resettlement communities participated in the study.

Coral benchmarks in the center of biodiversity.

There is an urgent need to quantify coral reef benchmarks that assess changes and recovery rates through time and serve as goals for management. Yet, few studies have identified benchmarks for hard coral cover and diversity in the center of marine diversity. In this study, we estimated coral cover and generic diversity benchmarks on the Tubbataha reefs, the largest and best-enforced no-take marine protected area in the Philippines.

PTSD's Underlying Dimensions in Typhoon Haiyan Survivors: Assessing DSM-5 Symptomatology-Based PTSD Models and Their Relation to Posttraumatic Cognition.

The recent changes in posttraumatic stress disorder (PTSD) symptomatology in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) call for a re-examination of PTSD's latent factor structure. The present study assessed six competing models of PTSD based on DSM-5 symptomatology using confirmatory factor analysis in a sample of young adult Filipino survivors of typhoon Haiyan, one of the strongest typhoons in the world ever recorded at the time of its landfall (N = 632). Furthermore, the differential relationships of the factors of the best-fitting model with posttraumatic cognitions were also investigated.

Degradation of polychlorinated biphenyls in aqueous solutions after UV-peroxide treatment: focus on toxicity of effluent to primary producers.

The combination of UV irradiation and hydrogen peroxide (UV-H(2)O(2)) was shown to be effective in treating water spiked with 2,2',4,4',5,5'-hexachlorobipheny (PCB 153), reducing its concentration by as much as 98%. To test the toxicity of the effluent, bioassays involving three species of primary producers were performed. Results showed the effluent exerting an adverse effect on the algae Scenedesmus bijugatus and the duckweed Lemna paucicostata.

Designing late-transition metal catalysts for olefin insertion polymerization and copolymerization.

The innovation of polyolefin with unique architecture, composition and topology continues to inspire polymer chemists. An exciting recent direction in the polyolefin field is the design of new catalysts based on late-transition metals. In this review, we highlight recent developments in rationally designing late-transition metal catalysts for olefin polymerization.

Individual and social dimensions of Filipino students' achievement goals.

Achievement goal theory assumes that self-instrumental (mastery) achievement goals are associated with academic achievement, whereas social-instrumental (performance) goals are not. However, research on Asian students shows that both mastery and performance-approach goals are positively related to achievement; possibly because achievement motivation in Asian cultures is socially oriented and not individually oriented. The current study explored the structure of the social and individual achievement motivation orientations, and how these achievement orientations and achievement goals were related to achievement of Filipino university students.

Exploring noun bias in Filipino-English bilingual children.

Researchers have suggested that there is a noun bias in children's early vocabularies brought about by features of adults' child-directed utterances, which may vary across languages (E. V. Bates et al.

A new rearranged dolabellane diterpene from the soft coral Clavularia inflata.

A new dolabellane type diterpene 1 has been isolated through its acetate 1a. The structure of 1a was elucidated by extensive 1D and 2D NMR spectroscopy and confirmed by mass spectrometry. The structure of 1 was deduced by comparison of its NMR spectral data with those of 1a, while its relative stereochemistry was deduced by NOESY.

Delivering maternal health care services in an internal conflict setting in Maguindanao, Philippines.

To improve access to maternal health care and family planning services in conflict-stricken Maguindanao province, southern Philippines, several non-governmental organisations have begun collaborating with local public health services. This exploratory study describes the experiences of local government service providers and two NGOs in a context of long-standing internal armed conflict, how and to what extent provision has been affected by the conflict and what has been done to overcome its effects. It is based on interviews with six health service coordinators and providers.

Exploring epistemological beliefs of bilingual Filipino preservice teachers in the Filipino and English languages.

In this study, the author investigated the epistemological beliefs of 864 bilingual Filipino preservice teachers using Filipino and English versions of the Schommer Epistemological Questionnaire (M. Schommer, 1998). The author conducted confirmatory factor analyses to determine the dimensions and structure of the epistemological beliefs.

Gene flow between species of Lake Victoria haplochromine fishes.

The haplochromine cichlid fishes of Lake Victoria (LV), East Africa, are a textbook example of adaptive radiation-a rapid divergence of multiple morphologically distinguishable forms from a few founding lineages. The forms are generally believed to constitute a "flock" of several hundred reproductively isolated species in a dozen or so genera. This belief has, until now, not been subjected to a test, however.

Filipino experience of ritual male circumcision: knowledge and insights for anti-circumcision advocacy.

Male circumcision is a well-publicised phenomenon, but much of what is known at the international level concerns neonatal medical circumcision in some Western countries and ritual circumcision among young men entering into adulthood in certain countries in Africa. This paper aims to add to this understanding by focusing on Filipino men's experience of ritual circumcision. Data were derived from a 2002 Philippine circumcision study-a component in a Southeast Asian research study of genital enhancement practices with an advocacy purpose.

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.

Language and modeling word problems in mathematics among bilinguals.

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.

Toxoplasma gondii antigens GRA1 (p24) and SAG1 (p30): a comparison of their stimulatory influence on T-cell activation and cytokine expression in in vitro cultures.

The influence of recombinant cell surface SAG1 (rp30) and secretory GRA1 (rp24) antigens (Ag) on T-cell activation and cytokine induction in vitro was compared. T-cell activity and the level of IFN-gamma, IL-10 and IL-12 expression in rp30-immunized T cells were considerably increased in the presence of rp30 Ags. IgG2a and IgG1 antibodies (Ab) were detected in sera of rp24- and rp30-immunized mice, with the secretory rp24 Ag having induced significantly higher titer of IgG1 Ab.

The effects of stating problems in bilingual students' first and second languages on solving mathematical word problems.

Approaches to learning and academic achievement of Filipino students.

Research has shown that a critical variable in determining academic achievement in different cultures and educational systems is approaches to learning. In this study, the author sought to determine whether this variable influences academic achievement among Filipino college students. The Learning Process Questionnaire (LPQ; J.

Language and mathematical problem solving among bilinguals.

Does using a bilingual's 1st or 2nd language have an effect on problem solving in semantically rich domains like school mathematics? The author conducted a study to determine whether Filipino-English bilingual students' understanding and solving of word problems in arithmetic differed when the problems were in the students' 1st and 2nd languages. Two groups participated-students whose 1st language was Filipino and students whose 1st language was English-and easy and difficult arithmetic problems were used. The author used a recall paradigm to assess how students understood the word problems and coded the solution accuracy to assess problem solving.
