This corpus-driven study explores the linguistics phenomenon of mental verbs in English song lyrics from 1960s until 2000s. This study aims to identify the frequency distributions of lexical verbs, mental verbs, and to analyze the language uses of mental verbs in the Diachronic Corpus of English Song Lyrics (DCOESL). Quantitative and qualitative methods of analysis were applied. First, quantitative data covering frequency distributions of general verbs was produced via LancsBox. Top three mental verbs in song lyrics were selected for analysis and discussion. The frequency distributions of mental verbs and collocations were produced via LancsBox. Collocational patterns were illustrated through collocational graphs constructed via LancsBox. Frequency distributions of mental verbs were compared to reference corpus Contemporary Corpus of American English (COCA) for the purpose of generalizing the findings from this study as representative of English language. The statistical data were subm.....

As coronavirus disease 2019 (COVID-19) spreads across the world, the transfusion of efficient convalescent plasma (CP) to the most critical patients can be the primary approach to preventing the virus spread and treating the disease, and this strategy is considered as an intelligent computing concern. In providing an automated intelligent computing solution to select the appropriate CP for the most critical patients with COVID-19, two challenges aspects are bound to be faced: (1) distributed hospital management aspects (including scalability and management issues for prioritising COVID-19 patients and donors simultaneously), and (2) technical aspects (including the lack of COVID-19 dataset availability of patients and donors and an accurate matching process amongst them considering all blood types). Based on previous reports, no study has provided a solution for CP-transfusion-rescue intelligent framework during this pandemic that has addressed said challenges and issues. This study ai.....

This study analyzes the context-based tasks in mathematics textbooks for grade ten and eleven vocational high school students in Indonesia. A vertical analysis was done based on the types of context, types of information, and cognitive demand types. This study is a descriptive qualitative study involving an external coder to ensure its validity and reliability. The data collection was conducted through text analysis and literature study. Whereas the data analysis used is content analysis. Based on the data analysis, it can be concluded that there are still little tasks with the relevant and essential context in the mathematics textbooks (10% for grade ten and 30% for grade eleven). Regarding vocational high school expertise, the tasks are relevant to vocational high school's specific expertise. Regarding the types of information, tasks with matching categorized are dominant: 54% in grade ten and 88% in grade eleven. For the types of cognitive demand, grade ten is dominated with reprodu.....

Incidences of food contamination often lead to behavioral changes among consumers, and the long-term outcome may jeopardize economic returns to producers. Therefore, this study aims to examine the relationship between food safety concerns, price consciousness, perceived severity, and food repurchase intention in the context of the canned sardine contamination issue in Malaysia. Moreover, the moderating and the mediating impact of perceived severity on repurchase intention are also uncovered in this study. A self-administered survey was distributed to a total of 400 respondents among consumers of canned sardine who had prior knowledge regarding canned sardine contamination. Empirical finding supported that price consciousness is related to repurchase intention. Perceived severity positively moderates the relationship between these two variables. The study results also reveal that, perceived severity fully mediates the relationship between food safety concerns and consumers? repurchase i.....

Science, Technology, Engineering, and Mathematics (STEM) subjects refer to school education policies and curriculum options to increase competitiveness in science and technology for students. Geography connects STEM disciplines with the application of geographical technology and tools, which can better understand cross-disciplinary phenomena to address critical problems. This study was carried out to validate the construct of the knowledge and skills in a geography STEM education instrument among prospective teachers in Malaysia. The respondents consisted of 400 students of semesters one to eight from the Bachelor of Education in Geography program, Universiti Pendidikan Sultan Idris, Perak, Malaysia, who were selected using a simple random sampling technique. The constructs studied were the knowledge and skills in geography STEM education. The data were analyzed descriptively and inferentially using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) for item compo.....

The advantage of computational tools over human brains is the speed, but the initiative ability of human brains is not owned by computational tools. The perfect combination of thinking and computing lays the foundation of science and gives birth to a series of achievements in technology. The introduction of technology through the subjects of Information and Communication Technology (ICT) in schools nowadays is just limited to using the applications. Computational thinking gives knowledge that builds structural thinking, critical power, and creativity by learning the computing process itself. These are what people need to enhance digital literacy. The way to learn it could be in many strategies. CS Unplugged was used in this research to deliver computational thinking in a simple way related to minimum infrastructure in the remote area for the children at elementary schools. Some activities were done as kinaesthetic learning in certain topics of CS Unplugged. This kind of method does not.....

Rare-earth oxides microparticles doped tellurite-based glass have been studied extensively to improve the capability of optoelectronic devices. We report a detailed comparison between two sets of glass series containing samarium microparticles and nanoparticles denoted as ZBTSm-MPs and ZBTSm-NPs, respectively. The two sets of glass have been successfully fabricated via melt-quenching technique with chemical formula {[(TeO2)0.70 (B2O3)0.30]0.7 (ZnO)0.3}1?y (Sm2O3 (MPs/NPs))y with y = 0.005, 0.01, 0.02, 0.03, 0.04 and 0.05 mol fraction. The TEM analysis confirmed the existence and formation of nanoparticles in ZBTSm-NPs glasses. The density of ZBTSm-NPs glasses was found higher than ZBTSm-MPs glasses due to the distributions of nano-scale particles in tellurite glass network. There was a linear trend of increment in the refractive index in both sets of glass series along with the concentrations of dopants. The refractive index of ZBTSm-NPs glasses was found higher than ZBTSm-MPs glasses .....

Good indoor air quality in school environment is crucial for teaching and learning processes, as well as student development. This study aims to identify the composition of PM2.5 and the main sources of it which influence the indoor and outdoor school environment. The PM2.5 sampling was conducted using a portable low volume air sampler and took place at three different primary schools. The chemical composition of PM2.5 is comprised of water-soluble inorganic ions (WSII) and potentially toxic trace metals. WSII (Cl?, NO3?, SO42?, Na+, NH4+, K+, Mg2+, Ca2+) were analysed using ion chromatography (IC) and trace metals concentrations (Al, Fe, Zn, Cr, Cu, Mn, Pb, Ni, As, Co, Cd) using inductively coupled plasma-mass spectrometry (ICP-MS). The results showed that the highest average for PM2.5 concentrations in an indoor classroom was recorded at the school located in the industrial area (23.5 ?g/m3) followed by urban (18.6 ?g/m3) and suburban (9.58 ?g/m3). The indoor to outdoor (I/O) ratio v.....
