Impact of communication competencies, job requirements and Academic performance on students' career development at the University of Hail, Saudi Arabia

Among the strategic competencies that will provide value to university students over the course of their career development plan are those that are relevant to both the needs of employers and the success of students in the classroom. This study aims to examine how students' communication skills, job requirements, and academic performance at the University of Hail, Saudi Arabia, affect their professional career development. An online survey was used to obtain the data collected for this study, which was then analysed with SPSS version 25 using multiple linear regression, making it a quantitative study. 210 students from Saudi Arabia's University of Hail were randomly selected to participate in this study's sample. Findings indicate that two of the three independent variables significantly affect the dependent variable. Therefore, a student's career development is significantly impacted by both job requirements and students’ academic performance, while communication competencies are not

How entrepreneurial competencies influence the leadership style: A study of Saudi female entrepreneurs

AbstractThis study examines a group of women entrepreneurs of small and micro businesses in Hail, Riyadh and Eastern regions of Kingdom of Saudi Arabia. The study aims to identify the particular style of leadership displayed by these women entrepreneurs; and whether all their competencies have the same or different influence on their task-oriented or people-oriented leadership styles. The respondents were initially identified through various organizations such as Wa’ed (Aramco’s entrepreneurship centre), MISK Foundation and Monsha’at. Subsequently, we finalized female-owned small businesses that are operating for minimum two years in their respective business area as our target respondents. The survey questionnaire was sent to 310 women entrepreneurs after obtaining their approval. A total of 211 filled surveys were received. The responses having repetition or missing data were deleted which resulted in 174 surveys which were analyzed using SPSS. Surprisingly, the results indicate that our respondents exhibit a higher score of task-oriented leadership style. The female entrepreneurs who possess high degrees of business and management, relationship, entrepreneurial and human relation skills are found to incline towards task-oriented leadership style. The relationship and entrepreneurial competencies show a positive influence on the people-oriented leadership style. On the other hand, business and management, as well as entrepreneurial and human interactions, show a positive influence on task-oriented style of leadership

Tunable Multi-Band-Stop Filters Using Generalized Fibonacci Photonic Crystals for Optical Communication Applications

In this study, a numerical investigation of photonic quasi-periodic Generalized Fibonacci (GF) (m, n) sequences is carried out in the visible spectrum. The transfer matrix method is employed to study the behavior of wave propagation through the photonic structures. Firstly and to highlight the importance of the GF structure, its transmittance spectrum is compared to those of periodic and ordinary Fibonacci structures. It is shown that the GF structure permits one to obtain multi-photonic band gaps (PBGs) separated by several resonance modes. The variation in the parameter m of the GF (m, 1) structure allows for the tuning of the number, the position and the width of these bands. By changing the parameter m, the wavelengths (650, 850, 1300, and 1550 nm) of the plastic and glass optical fibers can be allowed or forbidden to transmit through the structure according to the value of this parameter. In contrast, the variation in the parameter n for GF (1, n) hides all PBGs and only permits the appearance of several Kiessig fringes. The proposed structures can find application as tunable multi-band-stop filters for optical fiber wavelengths

An Empirical Study of the Contribution of Total Quality Management to Occupational Safety and Health Performance in Saudi Organizations

Working to ensure a safe and secure work environment for workers and employees has become an essential component of achieving organizational excellence in modern organizations. Occupational safety and health (OSH) programs help in attracting and retaining the workforce and human competencies, thus improving the operational and organizational performance of these organizations. Total quality management (TQM) is a management philosophy adopted by successful organizations to achieve sustainable business performance. This study aims to assess the level of implementation of total quality management and occupational safety and health in Saudi organizations and investigates the relationship between total quality management practices and occupational safety and health performance. Data were collected from a number of random organizations during the period November to December 2021. Based on a sample of 99 valid responses, empirical results were obtained through descriptive and advanced statistical analysis, indicating that TQM practices and OHS are highly implemented in Saudi organizations. The statistical results also showed that TQM practices have a significant positive impact on OSH performance in the surveyed organizations. The seven TQM fundamental pillars and the five OSH program components can be considered as essential success factors and fundamental pillars for TQM implementation in organizations and for OSH performance improvement

Wave oscillations in thermal boundary layer of Darcy-Forchheimer nanofluid flow along buoyancy-driven porous plate under solar radiation region

The significant contribution of current mechanism is to explore the periodical and fluctuating results of heat and mass flux of Darcy-Forchheimer nanofluid flow along buoyancy-driven porous plate under solar radiation region. Flow through a Darcy-medium has a wide range of applications such as the use of oil in various hydrothermal transfer control, radioactive nuclear disposal systems, water improvement, and filtration of water. The dimensional model is transformed into non-dimension for scaling factors. The primitive-based transformation is applied on steady and oscillatory parts for smooth algorithm in FORTRAN language machine. The convenient model is again reduced into algebraic pattern by using implicit finite difference method. The numerical and graphical results of velocity, temperature and concentration are executed by Gaussian elimination method. To enhance the frequency and wavelength, the impact of solar radiations, thermophoresis, Brownian movement, Schmidt factor, Prandtl factor, porosity and buoyancy pressure is applied on periodic nanoparticles with Darcy Forchheimer relation. The novelty of this proposal to explore the wave oscillations, amplitude and phase angle of thermal and concentration boundary layer of Darcy-Forchheimer nanofluid flow along buoyancy-driven porous plate under solar radiation region. It is noticed that the prominent wavelength and frequency in thermal and concentration boundary layers is generated under porous and solar radiation region. The significance of temperature variation increases as solar radiation, Brownian motion and thermophoresis increases. It is noticed that heat and mass transport enhances as Darcy-Forchheimer and modified buoyancy force increases. In thermodynamic systems, the Darcy-porous materials is prominent assumption that is employed in many domains, especially clinical science, petrochemical and structural engineering, geography, biochemistry and biological physics, and material science. For energy storage and energy conservation, the Darcy-porous material is required for batteries, fuel cells and super capacitors
