Impact of Liquidity Risk on the Profitability of Jordanian Islamic Banks

The study aimed to identify the ratio of liquidity on the return on assets and the return on equity, and to identify the impact of the liquidity ratio to total deposits, the legal liquidity ratio to the return on assets on one hand and the return on equity of the Jordanian Islamic banks on the other hand depending on the bank's size and the rate of indebtedness. The two researchers used the descriptive analytical approach relying on quantitative data extracted from the annual reports and final accounting statements of two Jordanian Islamic banks namely Jordan Islamic Bank and the Islamic International Arab Bank during the period (2008 – 2014). The researchers produced several results, most importantly: There is statistically significant impact of liquidity risk (liquidity ratio, liquid assets to total deposits ratio, legal liquidity ratio) on the return on assets (ROA) and the return on equity (ROE) on one hand and in the Jordanian Islamic banks on the other hand. There is statistically significant impact of the liquidity risks jointly (liquidity ratio, liquid assets to total deposits ratio, legal liquidity ratio) on one hand on ROA and ROE of the Jordanian Islamic banks depending on the bank's size on the other hand. The study recommends the following: The Jordanian Islamic banks should not over preserve liquidity and should look for tools to employ the excess liquidity keeping a suitable and balanced combination of assets and obligations in addition to a clear and flexible plan to be able to deal with any urgent liquidity crisis, depending on diverse sources and employment of funds in terms of different sectors and terms, and depending on short – term employment. The bank should also put acceptable limits to liquidity risks according to its acceptable total risk volume

Characterization and Performance of Minimum Quantity Lubricants in Through-Tool Drilling

This study characterized airborne microdroplet diameters and size distribution from two commercially available lubricants A and B for internal minimum quantity lubrication (MQL). The effects of air pressure, oil channel size, physical properties of lubricants on the resultant microdroplets and through-tool MQL drilling performance were studied. Airborne microdroplet diameters were highly sensitive to the coolant channel sizes and air pressure. Cluster method was used to divide microdroplets into smaller clusters for comparison. Experimental data show that the average airborne microdroplet of lubricant B was larger than that of lubricant A at different air pressures and channel sizes. The contact angle of lubricant A was at least 10° less than that of lubricant B when depositing on glass or aluminium. High-speed imaging showed the tendency of more viscous lubricant B sticking to the drill tip, and higher pressure and longer time was required to atomize this viscous oil. Built-up-edges were less significant when drilling A380 aluminium with lubricant A. Due to high machinability of A380 aluminium, variation of hole diameter and hole cylindricity were minimal when drilling with different lubricants. Insignificant improvement in hole quality was observed when drilling with excessive amount of MQL lubricants or high concentration of lubricant C in flood coolant

The reality of polarizing professional human resources in the Jordanian higher education institutions

The study aimed to identify the reality of polarizing professional human resources from the point of view of academics in Jordanian higher education institutions (JHEI), following the variables: gender, educational qualification, academic qualifications, years of service, and type of institution. The study followed a descriptive-analytical approach. The study sample comprised 674 faculty members working in various institutions of the JHEI. The researcher used a questionnaire comprising 24 items as a study instrument. The study’s findings revealed that the JHEI for polarizing professional human resources were ordinary. and that academic institution administrations encourage personnel to submit distinguished ideas. Also, they seek to adopt a philosophy of change as needed, while the administrations do not care about measuring the job satisfaction of employees. Periodically, it was found that JHEI encourage feedback from students to improve the quality of services and adopt modern technological means to provide their services

Trends of antimicrobial resistance in Escherichia coli isolates from urine cultures of women in Jordan: A 10-year retrospective study

Background: Urinary tract infection (UTI) is a common medical condition among women. E.coli is the most common causative organism. Appropriate understanding of the development of antimicrobial resistance over the past helps to establish efficient treatment strategies in the future. The study aims to discover antimicrobial resistance trends exhibited by E.coli strains isolated from women urine cultures over the past 10 years. Methods: A total of 1874 affected urine samples over the years 2009 to 2018 were collectively reviewed and classified according to the response they showed to 24 different antimicrobial disks in the laboratory. Relations between time and resistance evolutionary profiles were calculated. Results: Gentamicin (p value =0.039), Augmentin (p value =0.017), Cefoxitin (p value =0.001), Cefixime (p value =0.026) fulfilled satisfactory figures in terms of average resistance, regression of resistance, speed of resistance evolution, steadiness of performance, side effects, spectrum range and cost with high significance. Conclusion: Drugs that showed satisfactory figures are recommended for future treatment protocols in Jordan. &nbsp

Radiographic evaluation of the quality of root canal obturation of single-matched cone Gutta-percha root canal filling versus hot lateral technique

Aim: The aim of this study is to evaluate radiographically the quality of root canal filling in mesiodistal and buccolingual view when comparing matched cone condensation and warm lateral Gutta-percha condensation using system B heating instrument in a low-heat warm lateral condensation technique in0 vitro. Materials and Methods: A total of 40 mandibular premolars with straight single canals were divided into two groups with 20 each. The root canals were shaped by hand file and Revo-S rotary files to size (25, 0.06) at the end point, then they filled by Gutta-percha cone and meta-seal sealer. In group A, a single matched cone technique was used to fill the root canals. In group B, a hot lateral condensation using system B instrument at 101°C was performed. Result: The result of this study showed no significant difference in density of Gutta-percha fill in apical and coronal two-third when comparing matched cone root canal filling and hot lateral technique (P > 0.05). The only significant difference (P < 0.05) was in matched cone between buccolingual and mesiodistal view in the coronal two-third. Conclusion: Within the limitation of this study, single matched cone technique has a good density in the apical one-third as that of the hot lateral technique so it may be used for filling narrow canals. In the coronal two-third of the root canal, single matched cone technique showed inferior density of root canal filling which can be improved by using accessory cones Gutta-percha in wide canal

The study investigated whether these difficulties were affected by gender (males-females). To achieve the objectives of the study, the researcher designed survey consisting of 36 items. The sample of the study consisted of 30 male and female students enrolled in the field training course in the first semester of the academic year 2020/22021. The results showed that field training difficulties associated with the subscale of the students and supervisors were high. However, the difficulties related to the training center were medium. The study also showed no statistically significant differences in the difficulties between students due to the gender variable

Hesitancy towards COVID-19 Vaccines: An Analytical Cross–Sectional Study

Vaccination is the most promising strategy to counter the spread of Coronavirus Disease 2019 (COVID-19). Vaccine hesitancy is a serious global phenomenon, and therefore the aim of this cross-sectional study was to explore the effect of educational background, work field, and social media on attitudes towards vaccination in Jordan. We compared between medical personnel who were in direct contact with patients and non-medical individuals at Jordan University Hospital in terms of demographics, knowledge about COVID-19 vaccines, rumors received via social media, their trust in these vaccines, and the encouraging factors for vaccination. 646 individuals were enrolled in this study, of which 287 (44.4%) were from medical field, and 359 (55.6%) from non-medical field. 226 (35%) were planning to take the vaccine once available, with a positive response from 131 (45.6%) medical field workers, compared to 94 (26.2%) non-medical individuals (p &lt; 0.001). The social media rumor that was believed the most was the unsafety of these vaccines (n = 283; 43.8%). Only 163 (56.8%) of medical persons did not believe any of the circulated rumors, compared to 126 (35.1%) of non-medical persons (p &lt; 0.001). The effect of medical personnel advice (OR = 0.83; 95% CI = 0.70 to 0.98; p = 0.026) and social media (OR = 1.21; 95% CI = 1.04 to 1.41; p = 0.012) were significantly associated with the willingness to take COVID-19 vaccine once available. In conclusion, medical personnel and social media play a crucial role in increasing the society’s inclination towards vaccination by providing the community with updated evidence-based information about COVID-19 vaccines as an efficient medical countermeasure and by correcting the previously spread misinformation
