The determinants of customer internet banking resistance and the role of mediating variables in Yemeni Universities

Although internet banking has been widely adopted in developed countries, there is still a low percentage of internet banking adoption in Yemen, indicating a probable high resistance to internet banking. Hence, the objective of this research was to determine the direct predictors (attitude, subjective norm, perceived behavior control (PBC), credibility, trust, compatibility, self-efficacy and government support) of customer resistance, attitude, subjective norm, PBC and credibility towards internet banking. Additionally, this study examined the mediating effects of attitude, subjective norm, PBC, and credibility on the relationship between predictors and customer resistance to internet-banking behavior using Decomposed Theory of Planned Behavior (DTPB). A quantitative research survey was used whereby 900 questionnaires were distributed randomly to University employees. 451questionnaires were returned, representing a 50% response rate. After screening, 372 useable data sets were analyzed using the Structural Equation Modeling (SEM). The study found five significant predictors of customer resistance (attitude, credibility, compatibility, selfefficacy, and government support); three significant factors predicting attitude (government support, subjective norm and PBC); two significant predictors of SN (government support and self-efficacy); two significant predictors of PBC (compatibility and self-efficacy); and three predictors of credibility (trust, government support and PBC). It was also found that attitude fully mediated the relationship between subjective norm and customer resistance as well as between PBC and customer resistance. Contrastingly, attitude was a partial mediator between the relationship of government support and customer resistance. Likewise, credibility is a full mediator on the relationship between trust and customer resistance; PBC and customer resistance. Credibility also partially mediated the relationship between government support and customer resistance. Finally, the study contributes empirically by validating DTBP as an effective underpinning theory in explaining the internet banking resistance and that government should enact more stringent laws and policies to control the internet banking in Yemen

Comprehensive Performance Analysis of RPL Objective Functions in IoT Networks

As the movement for a vast implementation of IoT networks is rapidly accelerating, so many researchers are working to analyze the performance of RPL, the widely-used routing protocol for wireless sensor networks. The analysis usually involves a small number of metrics studied under a limited number of scenarios. In this paper however, we provide a comprehensive study for the performance of the two objective functions used in RPL; MRHOF and OF0, using the Cooja simulator in Contiki operating system. Using static-grid and mobile-random topologies with 25, 49, and 81 sender nodes including one sink node. Each topology was tested with three transmission ranges of 11, 20, and 50 meters to simulate sparse, moderate and dense networks. The selected metrics are convergence time, changes in DoDAG tree structures, average churn in the network, Average Power Consumption, Average Listen Duty Cycle, Average Transmit Duty Cycle, Average received packets, average lost packets, average duplicate packets, and average hop count. In fixed networks, the results show that OF0 usually perform better than MRHOF in terms of Energy Consumption, Convergence Time in the Static-Grid Topology, Listen Duty Cycle, and Transmit Duty Cycle

The Impact of the Faculty of Medicine, University of Gezira, Innovative Programme on its Graduates

Introduction: Programme evaluation is the collection and interpretation, through systemic and formal means, of relevant information which serves as a basis for rational judgment in decision situations. This study was conducted as part of the third programme development of the Faculty of Medicine, Gezira University 2010 – 2011. Objectives: The general objective is to study the impact of the Faculty of Medicine, Gezira University, innovative programme, on its graduates. The specific objectives include the evaluation of graduates' competences in the three main areas of domain of learning, i.e. Knowledge, skills and attitude. Materials and Methods: This is a Cross-sectional Study conducted in the period from13th. of January to 12th. of February 2011. The study population includes 146 consultants who have Gezira graduates training with them including house officers, medical officers and registrars. Excluded from the study all consultants who are academic staff members in the FMUG, who are Gezira graduates or who are involved in student training. A questionnaire was designed to answer the questions that address the objectives of the study covered in 32 questions, using a grading scales; 1 to 5: where 1= poor; 2= less than average, 3= average; 4= good; 5= excellent. Results: the response rate for the questionnaire was 73% (146/210), representing 146 consultants working in 23 hospitals in 12 cities. In the overall evaluation of graduates΄ knowledge and cognitive abilities, graduates were rated as good to excellent in (68.3%), average in (25.12%) and poor to below average in only a minority of the graduates. In the overall evaluation of graduates΄ skills and competences, graduates were rated as good to excellent in (72.33%), average in (20.81%) and poor to below average in only a minority of the graduates. In the overall evaluation of attitudes and ethical standards, graduates were rated as good to excellent in the majority (84.06%). In the overall classification, graduates were rated as good to excellent in the vast majority (82.6%), average in the minority (14.5%) and poor to below average in only a few cases. Conclusion The evaluation of graduates' competences is an important element in the educational programme evaluation. These results provide evidence in favour for the innovative educational programme and can encourage other medical schools to adopt it. Further studies are needed to cover other aspects of graduates' evaluations

Primary Tuberculosis of the Maxillary Sinus: A case report

Tuberculosis is up-to-date a leading cause of human suffering and loss of life. Although tuberculosis is a systemic disease, primary tuberculosis of the paranasal sinuses is rare. It should be kept in mind in any undiagnosed or atypical clinical infection or inflammation in this region. We present here a case of primary paranasal sinuses tuberculosis in an elderly Sudanese woman. Although Sudan is one of the highest three countries in the incidence of tuberculosis, this is the first case to be reported in Suda

Anatomical variations of nasal and paranasal sinuses among Sudanese patients undergoing CT scan evaluation at Antalya Diagnostic Center – Khartoum – Sudan, 2017

Introduction: The anatomical variations of the paranasal sinus are common among populations. These variations are asymptomatic most of the time, yet it may be associated with some inflammatory or allergic conditions. Knowledge of these anatomic variations helps in choosing the operative techniques, reducing the surgical complication rates and explains recurrence of disease. Objective: The aim of this study was to investigate the incidence and type of the anatomical variations of the paranasal sinus among adult Sudanese population by using CT scan. Patients and Method: This is a retrospective descriptive and health facility-based study, conducted at Antalya Diagnostic Center, Khartoum, during the period from July to September 2017. Included in the study all patients referred to the center for CT scan of the sinuses (n=151). A simple random technique was used for anatomical variations; with a sample size of 76 patients. Data collection sheet was used included demographic data and the anatomical variations. Data was analyzed using SPSS version 22. Results: The total number of patients diagnosed with variations was 76, which constituted of 50.3% of all patients included in the study. The age of patients ranged between 16 to 65 years, with a mean age of 36.46 (±11.12SD) years. The most frequent age groups were (16 to 25) and (26 to 35) years which constituted (52.63%) of the patients. Males were 34 (44.7%) and females were 42 (55.3%), with a male to female ratio 1:1.23. Relationship between age and gender with anatomical variants was found not statistically significant. Ninety variations were detected among the study sample. Nasal septal deviation was the commonest variation observed in (26.7%), followed by Concha bullosa in (20%), Onodi Cells in (11.1%), Agger nasi in  (10%), frontal sinus hypoplasia in  (10%) and other variations in ( 22.2%) of cases. Most of the variants were unilateral (81.6%) and were more on the left side in (46.1%) of cases. Conclusions and recommendations: the commonest variation was Nasal septal deviation, variations were common among the age group 16 to 35 years with slight female predominance. The study emphasizes the importance of CT scan for the detection of anatomical variations of the paranasal sinus in every patients planned for nasal or sinus surgery
