Systematic review of flipped classroom in EFL reading teaching and learning / Yao Juan and Dr. Revathi Gopal
No full textIn the realm of English as a Foreign Language (EFL) reading instruction, the flipped classroom approach has recently become a prominent and widely examined subject in educational research. Nonetheless, despite the growing interest in this area, previous studies have not thoroughly analyzed the implementation of the flipped classroom method in EFL reading instruction and learning from a systematic review perspective. The aim of this study is to explore the current trends and significant findings related to the use of the flipped classroom method in EFL reading instruction and learning. To accomplish this, 34 articles concerning the flipped classroom approach in EFL reading instruction and learning, published from 2014 to 2024, were retrieved from databases including Scopus, Science Direct, and Wiley Online. A systematic review methodology was utilized, with the articles being analyzed through a content analysis approach. The findings suggest that interest in the flipped classroom method increased among researchers in EFL reading instruction and learning following 2015, particularly with a significant rise in studies from 2020 to 2022. Furthermore, the majority of studies utilized mixed and quantitative research methods. Further research is necessary to evaluate the effects of the flipped classroom method in vocational college EFL reading classrooms. Further analysis revealed both the challenges and benefits linked to the flipped classroom method in EFL reading instruction and learning. The studies examined particularly emphasized the advantages of this approach in terms of its effectiveness. Based on this review, several recommendations are offered for practitioners and future research initiatives

ASIP data-plane processor for multi-standard wireless protocol processing
No full textEvolving Multi-Protocol Multi-Band Software Defined Radio (SDR) devices aim at supporting multiple protocols seamlessly and efficiently. The design of such radios necessitates flexibility in physical layer processing, flexibility in routing packets through processing engines and flexibility in radio frequency reception/transmission. This dissertation addresses an efficient implementation of flexible physical layer processing (PHY) for Interleaving, De-Interleaving and linear Minimum Mean Square Error (MMSE) detection in Multiple Input Multiple Output (MIMO) receivers through Application Specific Instruction Set Processors (ASIPs). The thesis defines and develops a WINLAB cognitive radio (WiNC2R) compatible data-plane ASIP architecture along with suitable hardware-software partitioning of the Processing Engine unit. Given the requirement of very significant design time and the lack of the flexibility after design, dedicated ASIC for PHY may not be a viable option although it has the best performance among all available options. The software application running on general purpose processor cannot satisfy the throughput requirements of the wireless standards. ASIPs provide a better trade-off between flexibility and performance, with the advantage of considerably lower design time than ASICs. We design an efficient multi-standard (802.11a, 802.16e/m) supporting Interleaver/De-Interleaver ASIP, satisfying the throughput requirements for all the modulation-schemes/data-rates in both of the standards. It can be programmed to scale for supporting future wireless standards (that use Block Interleaving/De-Interleaving). We also study viability of a flexible MIMO MMSE detector ASIP supporting variable MR (Number of receiving antennas) * MT (Number of transmitting antennas) operations. We have analyzed the implementation of an hardware-centric algorithm for MIMO detection on an ASIP and also improved its performance with the help of techniques such as fixed point implementation, Single Instruction Multiple Data (SIMD) and Very Long Instruction Word (VLIW). Analysis of the design performance results for MIMO ASIP indicates the limitations of hardware-implementation-specific algorithms on ASIP. We also provide the account of design decisions such as custom ports, memory interfaces and registers that are added to the data-plane processor ASIPs in order to substitute them for dedicated hardware engines in the WiNC2R platform.M.S.Includes bibliographical referencesby Mohit Gopal Wan

Systems biology of breast cancer
No full textBreast cancer, with an alarming incidence rate throughout the globe, has attracted significant investigations to identify disease specific biomarkers. Among these, oestrogen receptor (ER) occupies a central role where overexpression is a prognostic indication for breast cancer. The cross-talk between the responsible contenders of ER-associated genes potentially play an important role in the disease aetiology. Investigation of such cross talk is the focus of this thesis. The development of high throughput technologies such as expression microarrays has paved the way for investigating thousands of genes at a time. Microarrays with their high data volume, multivariate nature and non-linearity pose challenges for analysing using conventional statistical approaches. To combat these challenges, computational researchers have developed machine learning approaches such as Artificial Neural Networks (ANNs). This thesis evaluates ANNs based methodologies and their application to the analysis of microarray data generated for breast cancer cases of differing oestrogen receptor status. Furthermore they are used for network inferencing to identify interactions between ER-associated markers and for the subsequent identification of putative pathway elements. The present thesis shows that it is possible to identify some ER-associated breast cancer relevant markers using ANNs. These have been subsequently validated on clinical breast tumour samples highlighting the promise of this approach
Reading With EDSAW Acronym at Tertiary Level
No full textThis study aims to explore the use of the EDSAW acronym, a reading strategy in locating contextual clues systematically among tertiary-level students. It takes a quantitative research design to answer the research question, ‘How effective is the use of the EDSAW acronym in comprehending a reading text?’ The sample was selected based on a purposive sampling technique that comprised 10 students from a public university who scored band 4 in the Malaysian University English Test (MUET). The data collection technique involves a pre-test and a post-test. A reading text was given during the pre-test where students were tasked to locate contextual clues without using the EDSAW acronym. Then, the same participants were taught to use the acronym in finding contextual clues in a reading text. The mean scores of the pre-test and post-test were compared. The findings revealed that there was a significant increase of 2.3 points in the mean score of the post-test. This study highlights the need for teachers and students to use the reading strategy EDSAW acronym during the teaching and learning of reading in ESL classrooms and fills a void in the area of reading comprehension by enabling students to read more independently
Exploring symbolism in Hu Ru Gui by Malaysian Chinese writer Dai Xiaohua among Chinese tertiary students
No full textThis article explores English literature teaching, particularly the application of symbolism in a literary work called Hu Ru Gui among Chinese tertiary students majoring in English. Hu Ru Gui is a novel written by a Malaysian Chinese writer, Dai Xiaohua, which then became one of the literature teaching materials used at the tertiary level for Chinese students. This paper discusses the spiritual bloodline themes in the form of symbolism which runs through the whole literature work. The themes range from attitudes towards life and death, the national ridge of defending the motherlands dignity, and the patriotic values internalized deeply from generation to generation beyond time, location, and culture. A qualitative method was employed in the current study. Purposive sampling was used to select five students to participate in the study. The students were at the advanced level of English language proficiency. An interview protocol was applied as an instrument to collect data from a semi-structured interview. The feedback from the tertiary students was analysed through thematic analysis in the forms of themes, sub-themes, and codes. The research results revealed that the traditional values and patriotic values in the form of symbolism in Hu Ru Gui, the novel rooted in culture are the seeds of the motherland. Wherever and whenever a person goes, the seeds will bloom and inherited. Future research can focus on exploring how the themes, motifs, and symbols within the text resonate with Chinese tertiary students in Malaysia
