The Readiness of Government Schools to Deal with the Emergency and Crisis Situations from School Administrators View Point

The study aimed to identify the readiness of government schools to deal with emergency situations and crises from the viewpoint of their administrators. Totaling (326) male and female administrators, the sample was randomly chosen during the first semester (2018/2019), and a tool was developed consisting of (26) items distributed in three domains. The results showed that the estimates of the sample members on all domains came with a high degree of readiness, and showed that there are statistically significant differences attributable to the variable of the school gender and in favor of males, and the presence of statistically significant differences attributable to variable years of experience and in favor (from 10-5 years, and more than 10 years), and the absence of statistically significant differences attributable to the variable of the academic qualification with the exception of the domain of preparedness and prevention and in favor of postgraduate, and the presence of statistical differences due to the variable of the school level and in favor of the (secondary) schools. The study recommends employing early warning devices to detect any emergency occurring in educational institutions

An Indexed Approach for Expectation-Confirmation Theory: A Trust-based model

The present study utilised the Expectation-Confirmation Theory (ECT) as a theoretical framework to examine the temporal development of customer trust, satisfaction, and repurchase intent. In subsequent phases of the ECT, the significance of expectations in influencing customers’ attitudes towards confirmed trust and satisfaction was emphasised. The Trust-based Expectation-Confirmation model was therefore proposed to study trust at the appropriate level of abstraction to capture and analyse the relationships between Expected Trust, Perceived Trust, and the Confirmation of Expected Trust. The evaluation of the proposed ECT Trust-based model was conducted through a web-based survey with 559 participants, aiming to examine the direct and indirect approaches of measuring the Confirmation phase. Both approaches were found to be problematic in terms of the gap between the Perceived and Expected construct measured, which cannot be adjusted by the middle point on the Likert scale when using the direct approach either. This research article proposes the Indexed Approach as a new relevant assessment approach to transform data gathered from participants, which were measured throughout the Expectation and Perceived Performance stages, into a common format that could be used to determine each participant’s Confirmation. In order to validate the Indexed Approach, PLS path modelling evaluation and comparison for each approach were conducted; the results indicated that the Indexed Approach was the superior alternative to the direct and indirect approaches for transformation confirmation data to be used in the ECT model

Iatrogenic vesicovaginal fistula repair-experience at Prince Hussein Urology and Organ Transplant Center

Background: Despite the advances in technology in urology practice, and the surgical approach in dealing with iatrogenic vesicovaginal fistula repair, the most important is to achieve continent rate with minimum morbidity.Methods: From January 2006 to December 2017, the medical records and operative notes of 52 female (mean age 37 year) who had undergone transabdominal transvesical operative repair of their vesicovaginal fistula (VVF) at this institution were reviewed retrospectively. CT urography and diagnostic cystourethroscopy were the modalities of diagnostic tools. Trans-abdominal, transvesical repair with omental flap interposition were performed within 4-6 months in all cases. Patients were evaluated at two to three weeks initially, then at three months interval and later annually.Results: In present study, the most common presentation of VVF was urine leakage through vagina. In two third of the patients the etiology was due to hysterectomy procedure, regarding the location of the fistula, 94.2% of the fistulas located high in the posterior wall of the urinary bladder (supratrigonal), with the mean size of 2.2cm (range 5-25mm). 49 patients had single fistula (94.2%). The mean operative time was 110 minutes (range 60-130 minutes) and the mean post-operative urethral catheterization was 21 days (range 17-24 days). Almost all patients were continent after a mean of five months.Conclusions: Iatrogenic VVF is one of the distressing complications of gynecological procedure; delayed transabdominal transvesical approach with omental flap interposition is associated with excellent and durable results with minor morbidity. Standardization of the technique is a key success in the outcome of the repair

Angle of Incidence Effects in Reflectarray Antenna Design: Making gain increases possible by including incidence angle effects

The subject of whether or not it is necessary to include a feed field incidence angle in the design of main reflectarrays and subreflectarrays is discussed quantitatively in this article. The performance of reflectarray designs done with and without such incidence angle effects included are compared. The additional gain is achieved if the incidence angle is indeed included in the design process. The immunity of subwavelength elements to incidence angle effects is confirmed and illustrated using individual element patterns. Subreflectarrays designed with such subwavelength elements are shown to exhibit superior performance compared to those using half-wavelength ones

New observations related to the use of a dielectric substrate and an actual feed, in obtaining the interference pattern used in the synthesis of planar holographic antennas, are provided. It is demonstrated that the inclusion of the dielectric substrate, and actual feed effects, in holographic antenna realization, improves the antenna performance

Go Cashless! : Mobile Payment Apps Acceptance in Developing Countries : The Jordanian Context Perspective

Despite the expanding global usage of mobile phones in money transactions, the adoption of mobile payment systems in Jordan remains slow. This study employed the technology acceptance model (TAM) to identify the factors with a potential impact on mobile payment systems acceptance. The impact of perceived privacy (PP) and the mediating function of perceived certainty (PC) on the behavioral intention (BI) of mobile payment systems among Jordanian ministries were examined. Data obtained from 270 respondents were analyzed using partial least-squares structural equation modeling (PLS-SEM). The empirical findings show a positive link between perceived usefulness (PU) and PC on the BI of mobile payment systems. The mediation analysis demonstrated that PC partially mediated the association of PP with the BI of mobile payment systems. The final section concluded the paper by presenting the key theoretical and practical ramifications, as well as the research’s limitations and future directions.peerReviewe

Robust deep learning-based detection and classification system for chipless Arabic RFID letters

This work demonstrates a novel approach for reliable and robust identification and detection of realized chipless RFID Arabic alphabets using deep learning (DL) method. The undertaken classification problem of Arabic RFID tags of various fonts and sizes requires a classification technique that can learn long-term dependencies. Hence, a Bi-Long Short-Term Memory (BiLSTM) model is developed to classify 28 chipless Arabic RFID letters of different font types and sizes using their back scattered dual-polarized radar cross section (RCS) characteristics. The RCS frequency response of each Arabic letter tag reflects its signature electromagnetic characteristics that vary with the change in its shape (variations in font type and size). Firstly, an RCS dataset of 28 Arabic alphabet tags with three different font types (Arial, Calibri, and Times New Roman) and 13 different font sizes (16 mm–28 mm with a step size of 1 mm) are generated using Finite-Difference Time-Domain (FDTD) method in the frequency range of 1–12 GHz (1001 steps). The dimensions of the resulting dataset are [28 (letters) × 13 (font sizes) × 1001 (frequency steps) × 2 (polarizations)] × 3 (font types). Multi-class classification of the frequency-series data of all realized 28 alphabet tags of various font types and sizes makes the problem challenging and novel. The developed BiLSTM model can accurately classify the particular letter tag with specific font type and size based on the optimized network with employed Leave-One-Out Cross-Validation (LOOCV). The achieved accuracy with only Arial ([(28 × 13 × 1001 × 2)]), Calibri ([(28 × 13 × 1001 × 2)]), Times New Roman ([(28 × 13 × 1001 × 2)]), and combined data set ([(28 × 13 × 1001 × 2)] × 3) is 75%, 74%, 75%, and 89% respectively. The proposed Bi-LSTM model is shown superior when compared to other methods such as SVM, decision trees, and KNN, as it classifies the data with much higher accuracy for the considered multi-class data. The obtained accuracies of the compared models are 6.4% (SVM), 17.30% (tree) and 27.4% (KNN) respectively, while the developed Bi-LSTM model with optimized hyperparameters achieved an accuracy of 96%
