Indium Gallium Nitride Based Light Emitting Diode Using Pre-Roughened Backside (N-Face) Gallium Nitride Substrate
No full textThis project attempts to improve the performance of InGaN LEDs grown on GaN substrates. To achieve this goal, three frameworks were proposed. Firstly, by introducing GaN cap layer in multiquantum wells (MQWs). Secondly, by roughening backside (N-face) of GaN substrate using new etching solution and annealing the substrate before roughening. Thirdly, by roughening GaN substrate prior to LED growth
Agency Conflicts And Their Relationships To Firms Performance In Jordan
No full textThere are four main objectives of this study. First, to examine the direct relationship between earnings quality, corporate governance and firm performance. Second, to examine the relationship between earnings quality, corporate governance, and investment efficiency. Third, to examine the relationship between investment efficiency and firm performance. Fourth, to examine the indirect relationship between earnings quality, corporate governance and firm performance; with investment efficiency as a mediator
The Roles Of Open Innovation As A Moderator And Corporate Sustainability As A Mediator In The Relationship Between Risk Management Factors And Financial Performance
No full textCrisis management is based on a combination of open innovation and corporate sustainability. The literature on crisis management confirms that investigation of such a strategy is often limited. With the uncertainty that risk management factors (crisis proneness, risk-taking, knowledge of the crisis, decision making and crisis management) are active in corporate sustainability and financial performance. Many challenges and open issues facing the achievement of crisis management have not been observed yet. This study aims to explore the impact of risk management factors on financial performance through the mediating variable, corporate sustainability. In addition, The study explores the strength of the relationship between risk management factors and corporate sustainability through the interaction of open innovation. To this end, this study supplements the academic literature with an integration of partial least squares structural equation modeling (PLS-SEM)
Communication Strategies Framework In Wildlife Trafficking Using Social Media: A Netnography Study
No full textIn Malaysia, online wildlife trade is prevalent whereby social media sites such as Facebook (FB) and Instagram (IG) are used to advertise endangered animals. Even though online wildlife trade is a threat, not much studies have been conducted in the field of communication in Malaysia. Thus, this present study aims to examine the communication process between the sellers and buyers of wildlife on social media sites (FB and IG)
Nafkah Tertunggak: Pelaksanaan Dan Penguatkuasaan Undang-Undang Di Mahkamah Syariah Di Malaysia
No full textObjektif daripada kajian ini adalah menyelidik penguatkuasaan berdasarkan syariat Islam, kemudian proses undang-undang oleh pihak Bahagian Sokongan Keluarga (BSK) bermula daripada mediasi terlebih dahulu bagi menyiasat kemampuan terhadap penghutang, penguatkuasaan untuk dilaksanakan berdasarkan peruntukan undang-undang di Malaysia dan seterusnya cadangan menambahbaik kelemahan dalam pelaksanaan dan penguatkuasaan undang-undang
Crispr/Cas9-Mediated Suppression Of Dual-Specificity Phosphatase 6 (Dusp6) Inhibits Cell Viability, Growth, Survival And Adhesion In Ht-29 Human Colorectal Cancer Cell Line
No full textGlobally, human colorectal adenocarcinoma (CRC) was ranked third and second for the cancer incidence and mortality rate, while in Malaysia, it was ranked second and third for the cancer incidence and mortality rate. Despite its efficacy, the currently available CRC treatment has side effects and complications that compromise the patients’ well-being. Dual-specificity phosphatase 6 (DUSP6), a member of the MAPK phosphatase family, has been identified as pro-oncogenic, tumour-suppressive, or both in many cancers. Nevertheless, its role and significance in the human CRC are poorly studied. Therefore, this research aims to investigate the role and significance of the DUSP6 gene in CRC through modification of its gene expression
The Effects Of Collaborative Knowledge Building And Analytics-Supported Reflective Assessment On Learners’ Interaction, Collaboration, Conceptual Understanding And Learning Approach
No full textPremised on socio-constructivism, knowledge building and assessment theories, this study attempts to: (1) design a knowledge building environment, informed by knowledge building principles and analytics-supported reflective assessments, and evaluates its effects on learners’ conceptual understanding, approaches to learning, and conceptions of collaboration; (2) investigate the patterns of interaction in Knowledge Forum; (3) examine the role and process of reflective assessment in improving knowledge building; (4) characterize the dynamics of collaborative knowledge building, and (5) examine the role of interaction in Knowledge Forum (KF) on learners’ conceptual understanding. A mixed method (QUAN + QUAL) approach was adopted in this study involving 24 postgraduate students
Penang Young Viewers’ Interest And Perception Toward Local Mesomorphic Superhero Design (LMSD)
No full textThe purpose of this study is to understand and analyse how Penang's young viewers perceive and interest in local mesomorphic superhero designs (LMSD). The study begins by looking into the origins of local young people and superheroes, followed by several local professionals were interviewed to further support the idea and significance of the study
The Impact Of Neighbourhood Characteristics On Sense Of Belonging And Attachment In Residential Areas In Penang, Malaysia
No full textThe aim of the current study is to investigate how economic, physical, and social factors affect a person's sense of belonging and neighbourhood attachment. Understanding the people' level of neighbourhood attachment is the first objective. Other objectives of this study include examining the relationship between neighbourhood attachment and economic, physical, and social factors and the mediating role that sense of belonging plays in this relationship, particularly for residents of Penang Island
Hybrid modelling using decision tree and ordered regression: an application to health sciences research
Get PDFWith the increasing complexity of healthcare data, there is a need for more advanced and integrative predictive modelling techniques. This thesis presents a novel hybrid methodology integrating Decision Trees and Ordinal Regression using the R-syntax. The study objectives include the development of the hybrid method, measuring its efficacy and efficiency, validating its performance through predictive classification analysis, and optimising parameter estimates for optimised statistical inferences. The hybrid methodology uses decision trees, facilitated by visualisation tools, to identify influential factors that shape the model’s predictions. The bootstrap resampling method boosts the data set’s resilience and facilitates the development of an ordinal regression model. The introduction of the hybrid accuracy index enhances interpretability. The hybrid methodology is employed in two health sciences scenarios. In Case I, it predicts the frequency of toothbrushing among students, and in Case II, it predicts diabetic status using oral health indicators. This study introduces a hybrid method that generates numerical results along with graphical visualisation, enhancing the accuracy and efficiency of the parameter estimates. The findings of this study contribute to the development of an innovative approach to transforming predictive modelling in healthcare, contributing to future research methodologies for more precise decision-making
