The impact of usability, social and organisational factors on students' use of learning management systems in Saudi tertiary education

Advances in e-learning have reshaped universities worldwide. Universities place great emphasis on technology-enhanced learning development and are investing significantly in information technology infrastructure. However, in spite of this effort and investment, it seems that instructors and students do not fully benefit from learning technology, and more often Learning Management Systems (LMSs) remain underutilized. This is evident in Saudi higher education where LMSs have recently been introduced. Understanding the factors affecting the use of LMSs and prompting their engagement are therefore crucial to the success of such platforms. This study aims to fill this gap by examining usability, and organisational and social factors affecting the students’ intentions and use of LMSs in Saudi tertiary education. To this end, a theoretical framework was proposed that combined perceived usability attributes with the Unified Theory of Acceptance and Use of Technology (UTAUT) variables to identify the impact on students’ intention and use of the LMS. Furthermore, the study examined the moderating effect of demographic characteristics (gender, age, experience, and training) on the model’s proposed relationships. This study used a quantitative approach to validate the proposed model and test the research hypotheses. A cross-sectional survey method was adopted to collect the data. Using the probability multi-stage cluster-sampling technique, the empirical data were collected from five state universities in different regions of Saudi Arabia. The data were coded, cleaned, and preliminarily analysed using the Statistical Package for Social Science (SPSS) package. In total, 605 responses were usable for testing the measurement and structural model, employing partial least squares structural equation modelling (PLS-SEM) technique and SmartPLS software. The results reveal the significant drivers of student use of LMS and the moderating effect of demographics on the proposed relationships. The results confirm that the study model is valid and reliable to indicate the key factors that influence the use of LMS. The dimension of social influence emerged to significantly influence the students’ usage behaviour. The performance expectancy was affected by information quality and the system interactivity whereas the effort expectancy was influenced by system navigation, system learnability and instructional assessment. The statistical analysis reveals that six associations were moderated by the four proposed personal characteristics. In the light of the findings of this study, recommendations were put forward to universities to gain insights into the best way to promote e-learning system popularity and acceptance among students

Why do Saudi Nurses Leave Bedside Nursing: Findings from a Pilot Study

Aim: To explore the salient factors that account for Saudi nurses leaving bedside nursing to work in other fields of nursing.   Method: A non-experimental descriptive quantitative design was used to answer the research question of this pilot study. A valid and reliable questionnaire was used as an instrument for data collection. A snowball / purposive sample was used to collect the data from 46 Saudi nurses who had left bedside nursing in three hospitals in the Aseer region in southwest of Saudi Arabia. Data were analyzed by a professional statistician using descriptive statistics.   Findings: The salient factors for Saudi nurses’ decision to leave bedside nursing that were identified included: income (including allowances and financial incentives), administrative regulations, job satisfaction, and other miscellaneous factors   Conclusion: Although this pilot study has several limitations, the findings indicate that health care planners and policy staff, and nursing leaders in the Kingdom of Saudi Arabia need to develop strategies to address the issues expressed by Saudi nurses in regard to bedside nursing, particularly the need to improve (a) financial allowances and incentive systems, (b) the bedside work environment (e.g., by decreasing weekly working hours), and (c) the image of bedside Saudi nurses in the eyes of Saudi society.   Keywords: Saudi Nurses, Pilot Study, Bedside Nursing &nbsp

A comparative study between X-chromosome mapping of Sudanese and Egyptian Anopheles pharoensis theobald (Diptera: Culicidae) strains

Background: Current literature lacks information regarding Anopheles pharoensis malaria transmission patterns. Anopheles pharoensis succeeded in transmitting Malaria in Egypt. However, it was unsuccessful in doing the same in Sudan. From here arises these important questions: Why does it transmit malaria in Egypt but not in the Sudan or other Countries? Is it a Sibling species or a Sub-species? This investigation aimed to answer these questions by studying the genetics of Anopheles pharoensis collected from Egypt and Sudan.Methods: A comparative study was conducted in Egypt and Sudan to determine the population genetic structure of Anopheles pharoensis species based on chromosomal inversion of karyotypes. Fourth-stage larvae of Anopheles pharoensis were collected from Egypt (Faiyoum government) and from Sudan (Khartoum, Gezira and Sennar states).Result: Significant levels of differentiation were observed among the species studied.Conclusion: Investigations suggest that Anopheles pharoensis species collected from Egypt can transmit malaria due to the presence of an inversion in the X-chromosome. The lack of the aforementioned inversion probably prevented the transmission of malaria by Anopheles pharoensis in Sudan. The results above provide insight into malaria transmission patterns by Anopheles pharoensis. However, more needs to be done and hence it is recommended to undergo further research on genetics and morphological studies using molecular biological tool son Anopheles pharoensis in Sudan

IoT-Driven Visual Surveillance: Temporal Masking for Adaptive Motion Compensation in Imaging Technology

Global security is a matter of critical concern that requires adoption of advanced monitoring technologies. Efficient surveillance systems comprise extensive camera networks across large areas to ensure comprehensive coverage. However, the large volume of data generated by these networks poses challenges for traditional storage and computational resources. This paper presents an innovative video compression technique that focuses on optimizing data management in visual surveillance systems by selectively masking temporal information between frames. This technique introduces a specially designed adaptive masking filter, which hides the undetectable motion in video sequences and enhances video compression. The introduced masking technique uses an adaptive masking parameter ’q’ to improve frame prediction or to compensate for the masked temporal activity during decoding and achieves over 30% bit-rate reduction compared to the standard video encoding schemes, such as H.264/AVC. Moreover, the introduced technique also reduces the computational demands while keeping the quality of the output. This can be evidenced by a Peak Signal to Noise Ratio (PSNR) of 33.67 dB and a Structural Similarity Index (SSIM) of 92.7 in a traffic video sequence. The proposed technique holds the potential to be used in efficient IoT-driven video surveillance systems to process video frames efficiently without compromising quality

Perceived Risk of falls among Acute Care Patients

Purpose: In an effort to lower the number of falls that occur among hospitalized patients, several facilities have begun introducing various fall prevention programs. However, the efficacy of fall prevention programs is diminished if patients do not consider themselves to be at risk for falls and do not follow recommended procedures. The goal of this study was to characterize how patients in four different acute care specialist services felt about their risk of falling while in the hospital. Methods: One hundred patients admitted to the study hospital with a Morse Fall Scale score of 45 or higher were given the Patient Perception Questionnaire, a tool designed to assess a patient's perception of their own fall risk, fear of falling, and motivation to take part in fall prevention efforts. Scores on the Morse Fall Scale were gathered through a historical assessment of medical records. Descriptive statistics, Pearson's correlation coefficients, and independent sample t tests were used to examine the data. Results: The average age was 65, and around half (52%) were men and half (48%) were women. Based on their ratings on the Morse Fall Scale, all 100 participants were classified as being at high risk for falls. However, only 55.5% of the individuals agreed with this assessment. The likelihood that a patient would seek assistance and the degree to which they feared falling both declined as their faith in their mobility improved. Patients hospitalized after a fall exhibited considerably lower confidence scores and greater fear scores than patients who had not been injured in a fall. Conclusions: Patients who have a high fall risk assessment score may not believe they are at risk for falls and may not take any steps to reduce their risk. The prevalence of falls in hospitals might be mitigated by the creation of a fall risk assessment technique that takes into account both objective and subjective factors
