Framing Twitter Public Sentiment on Nigerian Government COVID-19 Palliatives Distribution Using Machine Learning

Sustainable development plays a vital role in information and communication technology. In times of pandemics such as COVID-19, vulnerable people need help to survive. This help includes the distribution of relief packages and materials by the government with the primary objective of lessening the economic and psychological effects on the citizens affected by disasters such as the COVID-19 pandemic. However, there has not been an efficient way to monitor public funds’ accountability and transparency, especially in developing countries such as Nigeria. The understanding of public emotions by the government on distributed palliatives is important as it would indicate the reach and impact of the distribution exercise. Although several studies on English emotion classification have been conducted, these studies are not portable to a wider inclusive Nigerian case. This is because Informal Nigerian English (Pidgin), which Nigerians widely speak, has quite a different vocabulary from Standard English, thus limiting the applicability of the emotion classification of Standard English machine learning models. An Informal Nigerian English (Pidgin English) emotions dataset is constructed, pre-processed, and annotated. The dataset is then used to classify five emotion classes (anger, sadness, joy, fear, and disgust) on the COVID-19 palliatives and relief aid distribution in Nigeria using standard machine learning (ML) algorithms. Six ML algorithms are used in this study, and a comparative analysis of their performance is conducted. The algorithms are Multinomial Naïve Bayes (MNB), Support Vector Machine (SVM), Random Forest (RF), Logistics Regression (LR), K-Nearest Neighbor (KNN), and Decision Tree (DT). The conducted experiments reveal that Support Vector Machine outperforms the remaining classifiers with the highest accuracy of 88%. The “disgust” emotion class surpassed other emotion classes, i.e., sadness, joy, fear, and anger, with the highest number of counts from the classification conducted on the constructed dataset. Additionally, the conducted correlation analysis shows a significant relationship between the emotion classes of “Joy” and “Fear”, which implies that the public is excited about the palliatives’ distribution but afraid of inequality and transparency in the distribution process due to reasons such as corruption. Conclusively, the results from this experiment clearly show that the public emotions on COVID-19 support and relief aid packages’ distribution in Nigeria were not satisfactory, considering that the negative emotions from the public outnumbered the public happiness

The impact of empowering internal auditors on the quality of electronic internal audits: A case of Jordanian listed services companies

This study emphases on the top management empowerments to internal auditors, namely, general qualification, electronic qualification and independence, affecting quality of electronic internal audits in the Jordanian Listed Service Companies. This paper used 144 usable questionnaires from internal auditors in the Jordanian listed service companies. The gathered data were analysed utilizing ``Statistical Package for Social Sciences (SPSS)''. The results reveal that general qualification, electronic qualification and independence have a significant effect on the quality of electronic internal audits, as supported by the resource-based view. Due to the importance of the service companies’ sector in the context of Jordan, the results are helpful for the internal audit profession and decision makers in offering new legislation for the internal audit profession. Future research may consider other factors that may hinder the quality of electronic internal audits, such as audit task complexity or organizational culture

Comparison of Oral, Tympanic and Fresh Urine Temperature in Healthy Young Adult Males in Kingdom Suadi Arabia

Background: Core body temperature (CBT) is commonly evaluated by measuring oral (OT) and tympanic membrane (TT) temperatures; however, there are considerable debates on which of these methods is the most appropriate.Objective: To evaluate concordance of OT and TT with CBT.Material and Methods: OT, TT and fresh urine temperature (FUT) were measuredsimultaneously in 45 apparently healthy young adult males from Buraydah, Qassim, KSA during July 2015. All readings were obtained between 7:00 and 10:00 pm according to the standard methods. FUT was used as indicator of CBT.Results: OT (36.35±0.41° C) was significantly higher compared with TT (35.99±0.81° C, P = 0.013) as well as FUT (35.55±0.76° C, P < 0.001). TT was significantly higher compared with FUT (P = 0.003). Using one sample t-test, the difference between OT and TT (0.36±0.92° C, P = 0.011), OT and FUT (0.80±0.90° C, P < 0.001) and TT and FUT (0.44±0.80° C, P = 0.001) were significantly above zero. Disconcordance of the OT, TT and FUT measurements are further illustrated by Bland-Altman plots. There were no significant correlations between OT and TT as well as between OT and FUT. However, TT correlated positively with FUT (r = 0.48, P = 0.001).Conclusions: OT and TT are inappropriate measures for CBT. CBT has influence on TT, but not OT.Key words: Core body temperature, oral, tympanic, urine
