The level of Employees\u27 Assessments of Psychological Well-Being and bullying at the Workplace and the extent of Inspiring leadership influence on them: Applied to government hospitals in Ma\u27rib governorate
No full textتوصلت الدراسات السابقة إلى أنَّ للتنمر آثارًا سلبية في مكان العمل، ومع أن هذه الدراسات قد حددت هذه الآثار، إلا أن كيفية التغلب على التنمر في مكان العمل لا تزال إحدى القضايا الهامة التي تحتاج إلى البحث والتحليل. لذلك واستنادًا إلى نظرية التعلم الاجتماعي نفترض في هذه الدراسة أنَّ القيادة الملهمة قد تحدّ من التنمر في مكان العمل.
كذلك سعت الدراسة إلى اختبار أثر القيادة الملهمة على الرفاهية النفسية. وتحليل الفروق في آراء وتقديرات مفردات عينة الدراسة حول التنمر في مكان العمل والرفاهية النفسية تبعًا لعدد من المتغيرات الشخصية والوظيفية.
جُمِعت البيانات باستخدام الاستقصاء من مجتمع الدراسة المتمثل في الأطباء والفنيين العاملين في أربعة مستشفيات حكومية بمحافظة مأرب، وبلغ عدد الاستمارات المستردة والصالحة للتحليل (229) من (254) استمارة.
توصلت الدراسة إلى أن القيادة الملهمة تؤثر سلبًا ومعنويًا على التنمر في مكان العمل، ولها تأثير إيجابي ومعنوي على الرفاهية النفسية، وتوصلت أيضًا إلى وجود اختلافات في تقديرات عينة الدراسة حول التنمر المرتبط بالعمل، والتنمر المرتبط بالشخص، والتنمر المرتبط بالترهيب الجسدي بناءً على بعض المتغيرات الشخصية والوظيفية.
قدمت الدراسة توصيات من أهمها: تعميم مفهوم القيادة الملهمة على مستوى مديري الإدارات، ورؤساء الأقسام، والتوعية بمخاطر ظاهرة التنمر، والاهتمام بمستوى رفاهية الأفراد النفسية عبر تزويدهم بالتدريب ذي الصلة على أساسٍ منتظم من أجل تقليل عواطفهم السلبية.Previous studies have concluded that workplace bullying has negative effects, and while these studies have identified these effects, overcoming workplace bullying remains an important issue requiring further research and analysis. Therefore, based on social learning theory, this study assumes that inspirational leadership may reduce workplace bullying.
The study also aimed to test the impact of inspirational leadership on psychological well-being. Analyzing differences in the opinions and assessments of the study sample regarding workplace bullying and psychological well-being, based on various personal and occupational variables.
Data were collected through a survey from the study community consisting of doctors and technicians working in four government hospitals in Ma\u27rib province. The number of retrieved and valid forms for analysis was 229 out of 254.
The study found that inspirational leadership has a negative and significant impact on workplace bullying, and it has a positive and significant effect on psychological well-being. The study also found differences in the study sample\u27s assessments of work-related bullying, person-related bullying, and physically intimidating bullying based on some personal and occupational variables.
The study provided recommendations, including generalizing the concept of inspirational leadership to the level of department managers and section heads, raising awareness about the risks of bullying, and addressing individuals\u27 psychological well-being by providing them with relevant training regularly to reduce their negative emotions

Resource Allocation in Fog Computing: A Systematic Review
Get PDFDespite the importance of resource allocation issues, there is no systematic, comprehensive and detailed survey on resource allocation approaches in the fog-computing context. In this article, we provide a Systematic Literature Review (SLR) on the resource allocation approaches in fog environments in the form of a classical taxonomy to recognize the state-of-the-art mechanisms on this important topic and provide open issues. The presented taxonomy is categorized into three main fields: centralized allocation, decentralized allocation, and integrated allocation (published between 2017 and March 2022). According to what is known in fog computing, load balancing and service placement are among the most important basic parameters that ensure service quality. These fields are classified into four methods, approximate, exact, fundamental, and hybrid. In addition, this article investigates resource allocation metrics with all advantages and limitations related to chosen resource allocation mechanisms in networks

Self-assessment of Internal Quality Assurance Mechanisms: An Empirical Investigation
Get PDFThis study examines the internal quality assurance mechanisms (IQAMs) at Mbarara University of Science and Technology (MUST) in Uganda through a self-assessment. A descriptive design and quantitative method are employed to investigate various quality aspects from all faculties and all units of MUST. The units of inquiry were (i) the internal stakeholders of MUST i.e. current staff and students, and (ii) the MUST Alumni. Participants were sampled using stratified simple random sampling where faculties and specific programs formed the various strata. The student samples were drawn from the admission lists while the alumni email contacts were drawn from the archived information in the Academic registrar’s office. Staff lists were drawn from the Human Resources office. The study utilized a structured questionnaire based on the Inter-University Council of East Africa (IUCEA) model. Based on the target population and samples, 384, 76, and 371 responses were received from students, staff and alumni respectively. The study revealed that IQAMs were implemented in various areas including teaching and learning, research and innovations, and community outreach, but gaps existed in policies for skills development and community engagement. While the university had established quality assurance policies, there were concerns regarding their awareness and implementation. Diverse opinions among students and staff emphasized the importance of considering multiple perspectives. Alumni feedback highlighted positive outcomes in employability and program satisfaction, but suggested improvements in integrating practical components and enhancing university-industry collaborations. Based on the findings, recommendations were made to MUST, including the development of specific policies, strengthening implementation strategies, enhancing student engagement, addressing staff viewpoints, fostering alumni involvement, and strengthening university-industry connections. These recommendations aim to enhance internal quality assurance mechanisms and overall education quality. The study provides valuable insights into quality assurance practices at MUST and emphasizes the need for continuous monitoring and improvement to sustain educational quality. Future work should conduct a qualitative study to gain a deeper understanding of the self-assessment study and also the underlying reasons, motivations, and experiences that could have influenced the aforementioned quantitative findings
