    Parenting styles (authoritarian and authoritative) and childhood traumatic experiences as predictors of emotion regulation among young adults in Malaysia

    Get PDF
    The insufficient ability of emotional regulation is a rising concern among Malaysian young adults. This has led them to a level of vulnerability when facing stressful events, where they struggle with mental health issues and suicidal attempts. Therefore, the present study examines the predictive role of parenting styles (authoritative and authoritarian) and childhood traumatic experiences on emotion regulation among young adults in Malaysia. A quantitative, cross-sectional design was employed to study 145 Malaysian participants, aged 18-29, recruited for the study. Parenting Style Questionnaire, Childhood Trauma Questionnaire-Short Form (CTQ-SF), and Difficulties in Emotion Regulation Scale-16 (DERS-16) were utilised to measure the variables of the study. Multiple linear regression analysis revealed that authoritarian parenting (β = −.220, p < .001) and childhood trauma (β = −.271, p = .012) significantly predicted poorer emotion regulation. However, authoritative parenting (β = −.051, p = .586) was not significantly associated with emotional regulation. The findings align with Social Cognitive Theory, emphasising how early environmental influences shape emotional self-regulation. To take note, authoritarian parenting's negative impact may also be exacerbated in Malaysia's collectivist culture, where emotional suppression is reinforced. Understanding these factors may be beneficial for developing effective interventions, including parenting workshops to reduce punitive practices and school-based programs to enhance emotional awareness. Limitations of the study include gender and ethnic imbalances in the sample (95.5% Chinese; 68.3% female) and reliance on cross-sectional data. Recommendations for future studies were suggested to improve generalizability and avoid possible bias

    Fertilizer types on corn yields (zea mays l.) in Kampar, Perak

    The global population is increasing, and optimizing food production has become a crucial way to address this challenge. Sweet corn (Zea mays L.) is a staple crop because it is both nutritious and affordable. However, in Malaysia, sweet corn production has not been self-sufficiency due to a paucity of knowledge in fertilizer management. This study investigated the effects of NPK 12:12:17, calcium boron (Ca/B), and biostimulant on the yield and anthesis timing of different sweet corn varieties commonly grown in Kampar, Perak, Malaysia. A split-plot design was done in UTAR Agriculture Park B, with two varieties, which were King Corn F1 316 and Sweetcorn King Raja SC 9001, and five different treatments: control (no fertilizer), NPK 12:12:17, NPK 12:12:17 + Ca/B, NPK 12:12:17 + biostimulant, and NPK 12:12:17 + Ca/B + biostimulant. The corn variety of F1 316 performed statistically significantly better than SC 9001 for cob’s fresh weight (g), cob length (cm), cob girth (cm), and the number of kernels per column. Both varieties showed statistically insignificant in 100-kernel weight (g). For fertilizer treatment, NPK 12:12:17 was statistically significant than control in producing a heavier 100-kernels weight (g). Moreover, a significant interaction effect was observed between variety and fertilizer type for 100-kernel weight (g), with the combination of variety F1 316 and NPK 12:12:17 yielding the heaviest kernels (g). These highlights the importance of distinguishing between apparent yield (whole cob) and actual yield (only kernels), suggesting that farmers should prioritize the corn varieties and types of fertilizer that may lead to a higher actual yield. NPK 12:12:17 can improve corn yield, while Ca/B supplementation is essential when deficiency is detected, and glycine-based biostimulants are beneficial when plants experience drought stress. Future studies should investigate how different fertilizer types affect the quality traits (i.e., shelf-life, physicochemical properties and nutrient content) of sweet corn

    Association between ultra-processed food consumption and sleep quality among students in Universiti Tunku Abdul Rahman (UTAR)

    Get PDF
    This cross-sectional study investigated the association between ultra-processed food (UPF) consumption and sleep quality among 324 undergraduate students at Universiti Tunku Abdul Rahman (UTAR) using the NOVA food classification system. NOVA categorizes foods into four groups based on processing level: unprocessed or minimally processed foods (UMPF), processed culinary ingredients (PCI), processed foods (PF), and ultra-processed foods (UPF). UPF are industrial formulations containing multiple artificial additives and minimal whole foods, typically high in refined sugars, unhealthy fats, and sodium including items like instant noodles, packaged snacks, and sugar-sweetened beverages. Using the NOVA classification system and the Pittsburgh Sleep Quality Index (PSQI), we assessed dietary patterns and sleep quality. Results revealed that UPF contributed a median of 521.84 kcal (27.87%) in daily caloric intake, which is the second largest contributor. A significant majority (n=221, 68.2%) of students exhibited poor sleep quality (PSQI > 5). Spearman’s correlation analysis demonstrated a moderate positive association between UPF consumption and poorer sleep quality (ρ = 0.48, p < 0.001), with female students reporting significantly worse sleep than males (p = 0.044, <0.05). Key mechanisms linking UPF to sleep disturbances included gut-brain axis dysregulation, systemic inflammation, and neurotoxic additives. Despite limitations such as self-reporting bias and a predominantly Chinese sample, this study highlights UPF as a modifiable risk factor for sleep disorders in Malaysian university students. Interventions targeting dietary habits and sleep hygiene are recommended to improve student well-being

    Financial distress detection using ensemble learning

    Get PDF
    Financial distress prediction is a crucial role, as an “early warning” for a company to address with the financial risk including restructuring the financial strategies and managing the operating costs effectively. Over time, several approaches have been developed for financial distress predictions, which are methods based on the financial ratios, single classification model and ensemble learning. However, few challenges have been found out from the previous approaches such as the imbalance datasets, limitations on the financial ratios and the auditor biases on selecting financial ratios. In this thesis focuses on ensemble learning are known to capture large and complex datasets and provide more robust result. The aim of the project is to identify the optimal ensemble learning technique in detecting financial distress risk

    Use AI to detect defect pin in electrical connector

    Get PDF
    This project aims to develop an intelligent inspection model capable of detecting defects in small electrical connector pins, which are critical components in many electronic systems. The work is structured into two primary components: data preparation and model development. In the data preparation phase, a custom dataset will be generated, featuring images of electrical connectors with three common types of pin defects: missing, shifted, and rotated pins. High-quality image data is essential for accurate model training and reliable detection outcomes. The model development phase leverages the YOLOv8 object detection algorithm, selected for its balance of speed and accuracy in real-time applications. Image processing techniques are employed to enhance dataset quality, and the dataset is annotated manually to ensure precision in model training. Performance evaluation will be conducted using several key metrics—accuracy, recall, precision, and F1 score—to assess the model's capability in identifying defective pins effectively. This project ultimately seeks to offer a practical and automated solution for improving quality control in electrical connector manufacturing processes, reducing the need for manual inspection and minimizing human error
