Research Title: Rhetorical Analysis of King Abdullah's English Speeches during the Covid-19 Pandemic
Author: Hanan Ali Amaireh, Published Year: 2023
Dirasat, 50(1)
Faculty: Arts
Abstract: This paper analyses King Abdullah's II English speeches during the Covid-19 crisis in a
corpus-based study. It investigates the rhetorical techniques employed by the King to
convince the audience. The data include 14 English speeches (8,694 words) delivered by
King Abdullah II of Jordan during the Covid-19 crisis, from January 2020 to August
2021. The rhetorical analysis is based on the classical Aristotelian classification of
rhetoric. It examines one canon of rhetoric, invention. In the analyzing invention, the
speaker's ethical appeals (ethos), emotional appeals (pathos), and logical appeals (logos)
will be examined in detail in a corpus-based study. The analysis reveals that King
Abdullah II employs ethical appeals to identify himself with the audience and create a
rapport with them by using first-person pronouns and lexical items like "my friends". The
quantitative analysis shows that the inclusive pronoun we and the pronoun I am used for
rhetorical reasons to convince the audience. Direct and indirect emotional appeals are also
used to stir the audience's emotions to call them to action. King Abdullah II uses logical
arguments such as an argument from statistics, quoting from the Holy Quran, and an
argument from a dilemma, inter alia, to convince the audience of his viewpoints and
persuade them to do specific actions.
Keywords: Keywords: Covid-19, Ethos, King Abdullah II, logos, pathos, rhetoric.

Research Title: Enhancing Software Effort Estimation with Pre-Trained Word Embeddings: A Small-Dataset Solution for Accurate Story Point Prediction
Author: Issa Ali Falah Atoum, Published Year: 2024
Electronics, 23(13)
Faculty: Information Technology
Abstract: Traditional software effort estimation methods, such as term frequency–inverse document frequency (TF-IDF), are widely used due to their simplicity and interpretability. However, they struggle with limited datasets, fail to capture intricate semantics, and suffer from dimensionality, sparsity, and computational inefficiency. This study used pre-trained word embeddings, including FastText and GPT-2, to improve estimation accuracy in such cases. Seven pre-trained models were evaluated for their ability to effectively represent textual data, addressing the fundamental limitations of TF-IDF through contextualized embeddings. The results show that combining FastText embeddings with support vector machines (SVMs) consistently outperforms traditional approaches, reducing the mean absolute error (MAE) by 5–18% while achieving accuracy comparable to deep learning models like GPT-2. This approach demonstrated the adaptability of pre-trained embeddings for small datasets, balancing semantic richness with computational e

Research Title: Bidenian and Harrisian Metaphors: A Corpus-Based Analysis of Joe Biden and Kamala Harris’ Political Discourse
Author: Hanan Ali Amaireh, Published Year: 2024
Jordan Journal of Modern Languages and Literatures, 16 (3)
Faculty: Arts
Abstract: This research analyzes some political leaders’ discourse which aims to achieve the objective of
persuading their audience to align with their respective viewpoints and policies. Applying the Conceptual
Metaphor Theory by Lakoff and Johnson (1980) and guided by the principles of Critical Discourse
Analysis by Fairclough (1995), this study examines a corpus of 40 speeches delivered by each of US
President Joe Biden and Vice President Kamala Harris. The analysis uncovers a recurrent utilization of
metaphors grounded in the domain of life, such as "LIFE IS A BATTLEFIELD," "LIFE IS A
JOURNEY," and "LIFE IS A GAME" by Biden. Similarly, Harris frequently employs "LIFE IS A
BATTLEFIELD," which conveys attributes of resilience and fortitude, reflecting her capacity as Vice
President. Furthermore, the analysis identifies another prevailing conceptual metaphor, "AMERICA IS A
PERSON," by Harris. These metaphorical expressions operate as persuasive tools, facilitating the
transmission of their respective political ideologies.
Keywords: Conceptual metaphors, corpus analysis, Critical Discourse Analysis, Joe Biden, Kamala Harris.

Research Title: The genetic landscape of autism spectrum disorder in an ancestrally diverse cohort
Author: Raida W. Khalil, Published Year: 2024
npj Genomic medicine , 9
Faculty: Science
Abstract: Autism spectrum disorder (ASD) comprises neurodevelopmental disorders with wide variability in
genetic causes and phenotypes, making it challenging to pinpoint causal genes. We performed whole
exome sequencing on a modest, ancestrally diverse cohort of 195 families, including 754 individuals
(222 with ASD), and identified 38,834 novel private variants. In 68 individuals with ASD (~30%), we
identified 92 potentially pathogenic variants in 73 known genes, including BCORL1, CDKL5,
CHAMP1, KAT6A, MECP2, and SETD1B. Additionally, we identified 158 potentially pathogenic
variants in 120 candidate genes, including DLG3, GABRQ, KALRN, KCTD16, and SLC8A3. We also
found 34 copy number variants in 31 individuals overlapping known ASD loci. Our work expands the
catalog of ASD genetics by identifying hundreds of variants across diverse ancestral backgrounds,
highlighting convergence on nervous system development and signal transduction. These findings
provide insights into the genetic underpinnings of ASD and inform molecular diagnosis and potential
therapeutic targets.

Research Title: Cytotoxic, a ntioxidant and αlpha amylase inhibitory activities of wild and N abali olive leaf extracts from Jordan
Author: Hani Jameel Mohammad Hamad, Published Year: 2024
Faculty: Allied Medical Sciences
Abstract: Abstract
Olive leaf extracts contain several phytochemical and pharmacological properties. This study evaluated the cytotoxic, antioxidant, α amylase inhibitory activities of aqueous, ethanol and ethyl acetate extracts fro m the Nabali, Muhassan and wild olive leaves grown in Jordan. Total polyphenols, flavonoids and flavonols contents, chelating power activity, total antioxidant activity and DPPH free radical scavenging activity of each extract were evaluated. The α amylase inhibitory activity of each extract was evaluated using CNP G3 assay while cytotoxicity was assessed against viability of MCF7 and MB MDA 231 breast cancer cell lines by MTT. The results showed that total polyphenol content was the highest in the ethanoli c wild leaf extract (113.97 mg gallic acid equivalent/g of dry extract). At a concentration of 100 µg/ml, the extracts from ethanolic wild leaf, ethyl acetate of wild leaf, and ethanolic Nabali leaf exhibited the highest chelating activity for ferrous ions (52.4%, 50.5%, and 47.2%). A ll olive leaf extracts significantly reduced MCF7 cell growth, while ethyl acetate wild leaf extract decreased MB MDA 231 viability. The findings revealed a robust correlation between the antioxidant, cytotoxic, and α amylase in hibitory activities of various olive leaf extracts. Further investigations are needed to identify cytoprotective effects of olive leaf extracts and the evaluation of its efficacy in vivo.
