The mechanism of mammalian mitochondrial quality control system
Get PDF The mitochondria perform an essential role in cellular metabolism by acting as a cellular energy powerhouse. It is also involved in several biological processes such as cell metabolism, stress signaling, calcium homeostasis, and reactive oxygen species(ROS) and apoptosis. Maintaining cellular physiological function is strongly dependent on mitochondrial quality control. mitochondrial malfunction will lead to various disorders. For this review, we evaluate the current understanding of the molecular mechanism of mitochondria quality control, which might also serve as an asset for organisms' health and the prevention of diseas
Reasons Behind Mis/Understanding English Conversational Implicatures by University Learners in Yemen
Get PDFEnglish, as a communication tool, plays an extremely significant role in cross-cultural communication. While it is true that language users can mean exactly what they mean in their utterances, it is also true that they can have their utterances mean much more than what they say. Speakers of English speak indirectly, and using conversational implicatures is a way to be indirect. And as sentences often express messages above and beyond their literal meanings, it is not surprising that pragmatic errors are found in language learning process of EFL learners' communication. Therefore, this study aims at investigating the factors beyond misunderstanding or understanding of English conversational implicatures among Yemeni EFL university learners. It follows an empirical analytical-descriptive method consisting of a test and an interview. Randomly, 50% of the study population was selected as the study sample. They were 62 Yemeni EFL university learners. A multiple-choice discourse completion test ( MCDCT ) and a semi structure interview were used for collecting the study data. The test contained eleven types of conversational implicature The collected data was analyzed quantitatively and qualitatively. The results reveal that different factors caused misinterpretation of conversational implicatures among Yemeni EFL learners. However, the differences in socio-cultural knowledge and indirectness are instrumental in the misunderstanding of conversational contexts in the study. While the familiarity of some conversational implicatures and formulaic pattern of others pose no challenge for the study subjects to interpret some of the test conversational implicatures. The study test conversational implicatures that are formulaic or familiar to the subjects are easy to grasp. Therefore, this study provides some recommendations that are expected to enable EFL university learners to develop their pragmatic competence regarding English conversational implicature and suggests a reconsideration of the existing methodologies on teaching English as a foreign language. Hence, this would ease the concern of EFL students about English conversational implicature, build up their confidence and enhance language learning
Social Responsibility and its Impact on Competitive Advantage of Service Business Organisations : A field study on mobile phone companies in Yemen.
Get PDFThis present study aims to investigate the effect of social responsibility (SR) on achieving the competitive advantage of service business organizations. The study is conducted on mobile phone companies in Yemen. The study uses a sample of 99 employees working in the main offices of these companies in Sana’a. The data of the study was collected through a self-administered Likert questionnaire survey. As being the most appropriate method to implement this study, descriptive statistical method was adopted to analyze the results. The findings indicate a positive role of the application of social responsibility in achieving the competitive advantage in mobile phone companies in Yemen. The study recommends that policymakers, regulators and companies should put strict disciplines and adopt different strategies to enhance the role of social responsibility. The study contributes to the strand literature of social responsibility. It addresses the issue of corporate social responsibility in a low-income country which opens an insight for regulators, policymakers, analysts, academicians and managers into the role of corporate social responsibility
Some fixed point results of F-Contraction mapping in D-metric spaces by Samet’s method
Get PDFThe aim of this paper is to study the F-contraction mapping introduced by Wardowski to obtain fixed point results by method of Samet in generalized complete metric spaces. Our findings extend the results announced by Samet methods and some other works in generalized metric spaces
The Level of Community of Inquiry (CoI) Presences in Online Classes among MSU BTESL Students
Get PDFCommunity of Inquiry (CoI) is a framework that acknowledges the importance of the environment in shaping the educational experience. According to this framework, teaching, social, and cognitive presences are essential for an optimal online learning experience. The purpose of this study is to identify the level of each of these presences in online classes among Management and Science University (MSU) Bachelor in Education – TESL (Hons). The instrument used for the research tool was adapted from the original CoI framework survey, (Arbaugh et al, 2008). The questionnaire consists of 20 items; six items for teaching presence, another six items for social presence and eight items for the cognitive presence. 263 students who are currently doing the programme participated in the study. The findings concluded that, all three presences are present in high or strong level in online classes among MSU BTESL students with the most substantial presence in online classes among MSU BTESL students being the cognitive presence, followed by the teaching presence and lastly the social presence
English Language Teachers’ Attitudes Towards Critical Thinking within Moroccan High Schools
Get PDFThis study addresses the restricted attention of critical thinking in the Teaching of English as a Foreign Language (TEFL) in Moroccan high schools, which is one of the new issues investigated in recent times. Many students could not think critically since their instructors could not implement critical thinking into their instructional practices every day. The primary bjective of this inquiry is to examine teachers’ attitude towards the use of critical thinking in the classroom. In this paper, the questionnaire was used to address only English language high school teachers. Descriptive statistical analysis of means, standard deviations, and percentages were used. The results showed that teachers held a positive attitude towards the use of critical thinking in the classroom. Therefore, they need not hesitate to introduce it in their teaching. Our findings strongly indicate that having an understanding of what really happened in the classroom will surely help shape the development of critical thinking in education. This suggests that further study could be carried to determine teachers’ level of use of critical thinking in Moroccan high schools
Building Information Modelling (BIM) and Energy Performance of Building - A Review
Get PDFNowadays, the advancement of technologies in the building industry may give a significant impact to the environment. The building sector contributes to the greenhouse gas emissions which may harm the environment and the high consumption of energy required high demand in burning the fossil fuel. These may effects the environment where, the carbon dioxide (CO2) has been significantly released to the atmosphere and harm the environment which may lead to global warming. In order to reduce the impact of greenhouse gas emissions and energy consumption, there is a need to develop a solution which may account these environmental problems. Conserving the energy of the building is one of the strategies to reduce the impact of greenhouse gas emissions to the environment. Recently, linking the building information modelling (BIM) to analyse the energy performance of the building has been spread widely. BIM has been recognized as a suitable tool to perform a building analysis in the early design stage which helps to model the energy use, flow of thermal, patterns of lighting and many more sustainable measures. BIM is believed able to help a designer to choose the best building design due to its concept of parametric change that assist the AEC industry to implement the sustainable design in an effective way and significantly improve the energy efficiency of building
