Translating a value-based framework for resilient e-learning impact in post COVID-19 times: Research-based Evidence from Higher Education in Kuwait
No full textThe covid-19 pandemic has changed people's daily lives and behaviors all across the world and has impacted practically every element of human existence. The introduction of remote education systems and the move toward online learning have had some of the most significant effects. The on-site operations of educational institutions, such as schools, colleges, and universities, have had to be suspended in order to stop the virus' spread. In order to effectively disseminate instructional material and guarantee the unbroken progression of students' academic endeavors, educators have been forced to look for novel approaches. The study used the Value-Based Adoption Model (VAM) as a conceptual framework to look into the factors that affected Kuwait's e-learning outcomes in the midst of the covid-19 pandemic. 382 students at Kuwaiti universities and colleges were the source of quantitative data collection. The findings revealed that peer interaction emerged as the most influential factor in shaping outcomes within the educational context of Kuwait, while instructors and course design factors were not significant. Using the VAM, this study investigated the impact of several factors on students' e-learning results during times of crisis. The research expands the existing knowledge base in the field on this subject and suggests developing a well-organized online learning crisis approach. The main contribution of this work is summarized on (i) An integrated framework for the quality of the e-learning experience in universities in post-covid-19 times and (ii) A resilient higher education institutional learning strategy model in post-covid-19 times. The findings of this paper can be generalizable to other Gulf Corporation Council (GCC) countries such as Kingdom of Saudi Arabia, Qatar, United Arab Emirates (UAE), Bahrain and Oman. This is due to the shared cultural traditions and values, along with similar educational systems among these nations
Once Upon A Time: A Framework for Developing Creative Writing in ESP and EAP
No full textCreativity is useful for enriching the quality of learning (Maley, 2015). Using English for creative learning purposes is essential for studying on various university degree courses. Writing is potentially considered as the most important skill although it is a difficult skill for Second Language (SL) learners to master (Nunan, 1999). One of the possible reasons for this is that it has not been well-emphasized and developed in English language materials (Alkhaldi, 2014; Tomlinson, 2015). This study focuses on writing, particularly, creative writing in English for Specific Purposes (ESP) and English for Academic Purposes (EAP) courses. The main purpose of an ESP course and EAP course is to improve traditional and technical writing skills for students, and this might be at the expense of creative writing. This study explores creative writing and its possible challenges. It also discusses the significance of creativity, creativity and the language learner, creativity and motivation, creative writing, and the role of creative writing in ESP/EAP. Finally, it elaborates and recommends a systematic, principled framework based on a review of the related literature for developing creative writing in ESP/EAP courses
An Analysis of English Language Theories: A Case Study
No full textLanguage is implicated in daily lives, and there are a large and open-ended number of activities (Cook, 2003), which involve language theories (Alkhaldi, 2011). This research analyses the language theories which are involved in the activities of Jordanian language materials. The researchers have chosen a sample from language materials used to teach English at Jordanian public high schools since 2015. An analysis checklist has been adapted and used, focusing on the analysis of language theories. The findings show that the students’ role is responsive rather than proactive. The dominant source of content is the materials, and the teachers’ role is overlooked in providing useful language content. Furthermore, the mental operations have not been taken to the deepest level to promote students’ creative and critical thinking skills. The findings also reveal that the materials have a sentence-based content, that is, the content provided as input to learners and content expected as output from the learners comprise individual words, phrases and sentences, and there are few opportunities for extended written and oral discourse. Consequently, it is recommended that teachers, researchers and materials developers should take into consideration such challenging findings to bridge the gap between theory and practice and to develop language materials effectively. In other words, the materials should continuously be analysed, evaluated, and developed in a systematic and rigorous way to have insights into the materials and the process of analysis for professional development purposes, and to help students improve their language learning process

Transformative leadership in Kuwait Direct Investment Promotion Authority: Investing in talent, innovation, and the next generation
No full textDigital transformation is becoming a necessity for all organizations all over the world. The importance of digital transformation is not only applicable to the private sector but also extends to the public sector. Kuwait boasts the Kuwait Direct Investment Promotion Authority (KDIPA), a pivotal entity entrusted with the mission of spearheading investment promotion across diverse sectors. More importantly, the focus has been recently on investing on digital transformation technologies where their statistics shows that 33% of their investment are in the emerging technologies. However, the success of KDIPA was not a mere chance or coincidence where it is really attributed to the transformative leadership that it has. It started to invest in projects that develop the talents and skills of Kuwaitis to create sustainable development and bring innovative technologies to the state of Kuwait. This chapter provides an overview of digital transformation and the role of KDIPA and its transformative leadership in attaining the Strategic Development Goals (SDGs) for a new Kuwait Vision of 2035
LANGUAGE MATERIALS OBSERVATION: PROFESSIONAL DEVELOPMENT TRAINING
No full textThe language classroom is an important site of research for investigations in the field of applied linguistics (Dörnyei, 2007), and the effectiveness of language theories and materials can be examined in a real-world setting in a systematic approach. Furthermore, materials development is the most effective way in field of linguistics and applied linguistics because the theories of language teaching and learning can be made meaningful and relevant by reference to practical procedures (Tomlinson, 2003). Observing the materials in the classrooms is one of the qualitative research methods for evaluating and developing language materials and reflecting on language theories which are explicitly or implicitly embedded in the activities of the materials (Alkhaldi, 2014). This study focuses on classroom observation of language materials which are rarely investigated in the field of applied linguistics taking into consideration that there is possibly a contradiction between what is one’s espoused theory and one’s theory-in-use, that is, what is done in reality. Therefore, this study analyzes the following aspects of observations of materials-in-use: reasons and purposes for materials observations, the environment, and the importance of materials observation study. It also discusses the methods and types of materials observation, observational schedules, the materials observer’s role, and a sample case study. Finally, it provides insights for teachers and researchers to reflect on language teaching and learning theories and develop their own practices towards effective language materials development and professional development training.

Intramedullary arteriovenous malformation with associated intranidal aneurysm: Case report and review of the literature
No full textBackground: Spinal arteriovenous malformations (AVMs) are rare vascular lesions presenting either with subtle progressive myelopathy or acute intramedullary/subarachnoid hemorrhage with associated neurological deficits. Far more uncommonly, AVMs are associated with intra-nidal aneurysms, which provide a further challenge in their management. Nevertheless, if untreated, these lesions lead to severe disability with a poor percentage of neurological recovery. Due to the lack of general guidelines, a neurosurgical and endovascular multidisciplinary approach is mandatory to achieve the best outcome in the management of such conditions. Case description: We provide a case of a 12-year-old girl presenting with a history of progressive lower limbs hyposthenia and sphincter dysfunction, presenting with acute excruciating back pain. Radiological assessments revealed a thoracic anterior intramedullary AVM associated with intranidal aneurysm, determining spinal cord compression. Discussion and conclusions: After a multidisciplinary evaluation, patient underwent a microsurgical resection of the lesion, with exclusion of the lesion from the spinal circulation and spinal cord decompression. On three-months neuroradiological follow-up, complete refilling of the spinal aneurysm was detected, and patient underwent a new microsurgical approach. Definitive exclusion of the vascular lesion was then achieved. Critical discussion of the choice of treatment along with a review of the pertinent literature is provided
Targeting PI3K/Akt/mTOR in AML: rationale and clinical evidence
No full textAcute myeloid leukemia (AML) is a highly heterogeneous hematopoietic malignancy characterized by excessive proliferation and accumulation of immature myeloid blasts in the bone marrow. AML has a very poor 5-year survival rate of just 16% in the UK; hence, more efficacious, tolerable, and targeted therapy is required. Persistent leukemia stem cell (LSC) populations underlie patient relapse and development of resistance to therapy. Identification of critical oncogenic signaling pathways in AML LSC may provide new avenues for novel therapeutic strategies. The phosphatidylinositol-3-kinase (PI3K)/Akt and the mammalian target of rapamycin (mTOR) signaling pathway, is often hyperactivated in AML, required to sustain the oncogenic potential of LSCs. Growing evidence suggests that targeting key components of this pathway may represent an effective treatment to kill AML LSCs. Despite this, accruing significant body of scientific knowledge, PI3K/Akt/mTOR inhibitors have not translated into clinical practice. In this article, we review the laboratory-based evidence of the critical role of PI3K/Akt/mTOR pathway in AML, and outcomes from current clinical studies using PI3K/Akt/mTOR inhibitors. Based on these results, we discuss the putative mechanisms of resistance to PI3K/Akt/mTOR inhibition, offering rationale for potential candidate combination therapies incorporating PI3K/Akt/mTOR inhibitors for precision medicine in AM
Global Health and Peace: The Elusive Path with a Focus on Palestine, Ukraine, and Venezuela

Peace and health outcomes reflect shared fundamental values related to the achievement of a balanced holistic condition on the individual and collective level. This causal relationship between social inequity and health requires special attention to be paid to the impact of political instability and structural violence on undermining health systems in conflict zones. The mutual dependency between peace and health means that peace cannot be achieved without the existence of physical, mental, social, and spiritual health, and holistic health cannot be sustained under violent conditions. The interrelationality of peace and health as mutual conditions shapes our understanding of global solidarity and advocacy in relation to health diplomacy and peace promotion if addressed equally across all conflict zones This commentary analyzes the unique interdisciplinary contextual factors that contribute to or undermine the realization of global health and peace in three active conflict zones: Palestine, Ukraine, and Venezuela. Contextual analysis, review of the evidence, and synthesis of the authors’ perspectives were used. The health-peace nexus remains a theoretical approach and lacks real application in most settings under crisis. Peace is a multifaceted phenomenon that necessitates the participation, dedication, and action of all sectors and stakeholders in the global societies, including health policymakers, scientists, professionals, and people. Both the “right to health” and the “right to peace” even at the minimum remains unfulfilled, particually in Palestine, and can be realized through two trajectories: (1) honest, responsible, and fair accountability, transparency, and political commitment empowered by reliable global health diplomacy for maintaining peace, eliminating the roots of injustice, and protecting health systems, and (2) equitable and real implementation of peace-health approaches, policies and actions driven by monitroing mechanims that promote health, well-being, health security and equity for all nations under conflicts.Plain Language Summary: Countries under conflict are facing multiple, (re)emerging and complex crises aggravated by increasing structural social, political, and economic pressures and inequities that mainly impact people’s health and health systems. Global health and politics integration is key for promoting health through building reliable and lasting peace in these countries.The existing global health governance and diplomacy structures of peacebuilding for health are powerless, ineffective, and still polarized, thus global health actors up for failure when it comes to addressing the root causes of the crisis and building/maintaining a reliable and lasting peace in countires under conflict.Crises including political pressures, historic suffering due to coloniality, protracted conflicts, lack of firm enforcement of international laws, including diplomatic, humanitarian, and human rights laws, hypocritical standards of intervention, health inequity and injustice, and absence of impactful and unfied global rights-based advocacy movements from civic, academic, labour, and professional societies, all impede the creation of peaceful societies that promote health and vice versa.Palestine, Ukraine, and Venezuela reflect diverse contexts where clear major disparities are present in terms of global solidarity and advocacy, levels and forms of interventions, global attention, magnitude of losses, and actors’ willingness to promote the health-peace approach and to change realities.Continued impunity, partiality, and injustice undermine health-peace promotion and scale up local and global health disruptions, and the common challenges of suboptimal health status should be sufficiently handled based on equal rights, equity, accountability, and transparency regardless of variations in geography, ethnicity, region, political context.Keywords: global health, peace-health nexus, Palestine, Ukraine, Venezuel
