Assessing vocabulary size in Malaysian preschoolers: insights from the Malaysian English cross-linguistic lexical task and parents of multilingual children questionnaire
No full textThis paper introduces the first freely available Malaysian English vocabulary size assessment for 4- to 6-year-old Malaysian children: the newly developed Malaysian English Cross-linguistic Lexical Task (MECLT). Using MECLT scores to measure vocabulary development, the study further explores the efficiency of two approaches: the sum of the number of home languages versus a language exposure composite score, in classifying children’s language profiles (monolingual, bilingual, or multilingual). Sixty children who predominantly speak English at home were assessed on their comprehension and production of nouns and verbs. Significant age effects in MECLT scores were observed between 4- and 5-year-olds, as well as between 4- and 6-year-olds, suggesting that the MECLT is a valuable tool for capturing vocabulary growth among Malaysian preschoolers. Furthermore, in analysing predictors of MECLT scores, the study found that the home language model, which includes age and the number of home languages, was the most accurate predictor of vocabulary size. In contrast, the language exposure composite score model, while detailed, did not significantly enhance predictive accuracy and proved to be more complex and time-consuming
Evaluating grease trap management practices: a case study from Seri Kembangan, Malaysia
No full textSewerage blockages due to oil and grease deposition discharged from food premises remain a persistent issue globally. This study evaluates the degree of compliance of food premises in Seri Kembangan, Selangor, Malaysia with grease trap guideline, and investigates the factors affecting restaurants' compliance performance. Data were collected from 36 restaurants through a questionnaire-based interview consisting of questions about grease trap installation, operation, maintenance and waste disposal, followed by a walkthrough of the kitchen. Results show that 72.22% of food premises' compliance levels were good, 5.56% were excellent, 13.89% were moderate and 8.83% were poor. Food premises equipped with appropriate facilities and financial resources execute grease trap practices more diligently. A significant association was observed between location with compliance level (p < 0.05) determined via Fisher's Exact Test. This study revealed the grease trap practice gaps and provided a basis for improving regulations and enforcement
Green electrosynthesis strategies of SnO catalysts for enhanced photodegradation of 2,4-dichlorophenol
No full textThe electrogeneration of SnO using an environmentally friendly approach was assessed by utilizing three different electrolytes: N,N-dimethylformamide (DMF), plant extract (PE), and a combination of PE with a deep eutectic solvent (PE-DES). The catalysts were characterized through FTIR, XRD, BET surface area analysis, and UV–Vis DRS to determine their structural and optical properties. The photocatalytic degradation of 2,4-dichlorophenol (2,4-DCP) was then evaluated for each catalyst under visible light exposure. At pH 3, SnO-PE-DES exhibited the highest degradation rate of 99.22%, making it the most efficient catalyst. SnO-DMF showed a degradation efficiency of 93.81%, while commercial SnO achieved 86.60%. The degradation efficiency of SnO-PE alone was only 23.46%, but incorporating DES significantly improved its performance. This enhancement is attributed to DES's ability to promote a more organized SnO structure, increasing the surface area and improving interactions with 2,4-DCP molecules. Due to its environmentally friendly synthesis and outstanding photocatalytic activity, SnO-PE-DES was selected for further optimization studies. This catalyst demonstrates great potential for photocatalytic applications in wastewater treatment. Its impressive performance under visible light, coupled with its eco-friendly synthesis, makes it a promising candidate for large-scale environmental remediation projects powered by solar energy
