Twitter sentiment analysis to understand students\u27 perceptions about online learning during the Covid\u2719

In 2019, the Covid-19 pandemic led to emergency changes in the educational sector as a precautionary measure to limit the spread of the Covid-19 virus and protect the health and safety of students. Educational institutes couldn\u27t escape this havoc; by April 2020, 189 countries had suspended school, affecting 89 percent of the world\u27s students. Since the epidemic began, online learning has completely taken over the educational industry, leaving students with no choice but to adapt to the brand-new virtual learning environment. Consequently, people turned to social media, such as Twitter, to express their feelings, opinions, and concerns about online learning as an alternative to traditional physical classes. The new online learning platforms, associated technologies, and procedures have been widely discussed on Twitter. In the proposed study, we have presented a systematic approach to analyze the public opinions and perceptions about online learning using Twitter sentiment analysis (TSA) through Twitter\u27s API and term frequency-inverse document frequency (TF-IDF) technique. Further, we classified the sentiments into certain clusters, such as positive, negative, and neutral, using a text mining approach (i.e., lexicons). Moreover, we have uncovered these sentiments and visualized the clusters using visualization techniques such as word clouds and bar charts. Additionally, by using TF-IDF, we measured the strength of words that people use to express their opinions about online schooling and explored to what extent it affects the overall results of our analysis

Prescribing Antibiotics for pediatric dental patients in Jordan; knowledge and attitudes of dentists

Objective: The inappropriate use of antibiotic in treating children has been observedin the treatment of dental infections. Recent surveys reported that dentistsin several countries have modest knowledge about antibiotic prescribing. The aimof this study was to investigate the knowledge and attitude of a group of Jordaniandentists treating children towards antibiotic prescribing.Methods: A written questionnaire was distributed during a meeting of the JordanianSociety of Paediatric Dentistry. The questionnaire included questions aboutthe knowledge and attitudes of dentists toward dental antibiotic prescribing tochildren.Results: Amoxicillin was the most popular antibiotic (62.9%) to be prescribed bydentists treating children. A lesser percentage (29.7%) prescribe combination ofantibiotics, and around 37% prescribe antibiotics for duration longer than 5 days.Erythromycin was the most popular alternative to amoxicillin (77.8%) followed byclindamycin (22.2%). A number of antibiotics were prescribed for non-indicatedclinical conditions like pulpitis and gingivitis. More than 50% of the sample prescribedantibiotics for non-scientific reasons like the “need to delay treatment†and“sterilization not guaranteedâ€.Conclusion: There is a need to improve awareness of Jordanian dentists regardingantibiotic prescribing to children particularly in the aspects of type of antibiotic tobe used for patients allergic and non-allergic to penicillin, duration of prescribing,and clinical indications. Dentists also should be discouraged to prescribe antibioticsbased on non-scientific/social factors

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

Causes of death and survival analysis for patients with retinoblastoma in Jordan

PurposeTo analyze causes and prognostic factors for death among Retinoblastoma (Rb) patients treated at a single specialized tertiary cancer center in Jordan.MethodsWe reviewed the mortality causes for all Rb patients who have been treated at the King Hussein Cancer Center between 2003 and 2019 and were followed for at least 3 years after diagnosis. The main outcome measures included demographics, laterality, tumor stage, treatment modalities, metastasis, survival, and causes of death.ResultsTwenty-four (5%) of the 478 patients died from retinoblastoma and 5-year survival was 94%. The mean age at diagnosis was 15 months (median, 18 months; range, 4–38 months); eight (33%) received diagnoses within the first year of life. Eleven (46%) were boys, 16 (67%) had bilateral disease, and 3 (13%) had a positive family history. The stage for the worst eye was C for 1 (4%) patient, D in 6 (25%) patients, and E (T3) in 15 (63%) patients. Two patients had extraocular Rb at diagnosis, and four of the patients who had intraocular Rb at diagnosis refused treatment and then came back with extraocular Rb. In total, extraocular disease was encountered in six eyes (six patients). After a 120-month median follow-up period, 24 patients (5%) died of second neoplasms (n = 3) or metastases (n = 21). Significant predictive factors for metastasis and death included advanced IIRC tumor stage (p < 0.0001), the presence of high-risk pathological features in the enucleated eyes (p = 0.013), parental refusal of the recommended primary treatment plan (p < 0.0001), and extraocular extension (p < 0.0001).ConclusionThe 5-year survival rates of Rb patients in Jordan are as high as those in high-income countries. However, 5% are still dying from metastatic disease, prompting the need for awareness campaigns to educate the public about the high cure rates and to prevent treatment abandonment
