Faculty: Science
Abstract: This cross-sectional study investigates Toxoplasma gondii and Neospora caninum among 445 recently spontaneously aborted (RSA) Jordanian women using ELISA and indirect fluorescent antibody (at a cut-off value of 1/200) tests, respectively. The type of hospital, age, cat and dog contacts, raw and barbecued meat and wild plant consumption, number of abortions, and stillbirths were tested as independent variables using univariate and multivariate logistic regression analyses. The true seroprevalences were 22.1% for T. gondii-IgG, 22.7% for N. caninum-IgG, 2.6% for T. gondii-IgM, 10.6% for N. caninum-IgM, 0% for T. gondii-IgG and IgM, 6.7% for N. caninum-IgG and IgM, and 4.6% and 0% for both parasite IgG and IgM, respectively. T. gondii-IgM-seropositivity was associated with the number of abortions with odds ratios (OR) of 2.4 and eating barbecued meat (OR = 0.12). N. caninum-IgG-seropositivity was associated with having a dog in the house (OR = 2.6), and with stillbirth (OR = 0.1). N. caninum-IgM was associated with visiting a private-hospital (OR = 2.7). RSA Jordanian women are equally exposed to both parasites with significantly (p < 0.05) higher seroprevalence of N. caninum-IgM compared to T. gondii-IgM suggestive of active infections among RSA women in Jordan.

Research Title: Earnings management, ownership structure and the firm value: An empirical analysis
Author: Hassan Hamad Aldboush, Published Year: 2021
Journal of Management Information and Decision Sciences, Research Article: 20
Faculty: Business
Abstract: There are always conflicts of interest between managers (agents) and owners (leaders), but not necessarily the degree of disagreement. This is due to a conflict of interest or a division of responsibility. The purpose of this research is to look at the effects of earnings management and ownership structure on business value. The public firms included for this research were listed on the Amman Stock Exchange between 2015 and 2019. The purposive sampling strategy is used in this research to examine the sample, providing seven businesses as the test sample. In the regression analysis, multiple regression and descriptive statistics were applied. According to the conclusions of this research, earning management, managerial ownership, and institutional ownership have minimal effect on business value. Aside from that, the findings suggest that family ownership has a significant favorable influence on business worth. To maximize the firm's valuation, it is recommended that these firms strictly adhere to the CG mechanism as a requirement. The function of CG as an independent or moderating variable, on the other hand, is still debatable.
Keywords: Earnings management (EM); Firm value (FV); Ownership structure (OS).

Abstract: The study aimed to shed light on an important mechanism for the construction of the text in the Cordovan Maqama, one of the Andalusian Maqamat in the 6th century AH, that is the mechanism of intertextuality. The study starts with introducing this Maqama and the context of its production besides a summary of its plot, and then the definition and importance of intertextuality are introduced before explaining the main intertextual forms that are found in this Maqama via a statistical process which highlights the role of intertextuality in constructing the Maqama text on both the aesthetic and the thematic aspects. The main forms of intertextuality in the Maqama are the religious intertextuality, especially the Quranic one, and the literary intertextuality, such as poetic and proverbial intertextuality, in addition to references to traditional figures. The research method used was the statistical one in combination with the descriptive and formalist methods. The study ends with several conclusions, the most important of which is that literary intertextuality, particularly poetry, is the most common in the Maqama, while the rest of the forms are present almost equally, and the style of intertextuality in most of them takes the form of direct quotation.

Research Title: Phytochemical and Biological Investigation of Aristolochia maurorum L
Author: Soha Telfah, Published Year: 2006
Verlag der Zeitschrift für Naturforschung, 61
Faculty: Pharmacy
Abstract: Aristolochia maurorum L. of Jordanian origin has been investigated phytochemically, quantitatively, and biologically. Three atypical alkaloids, namely aristolochic acid I (1), aristolochic acid II (2) and aristolochic acid IIIa (3), have been isolated and identified. Of these known 1-phenanthrenecarboxylic acids, 2 and 3 are reported for the first time from this species. The identified compounds 1-3 were first evaluated biologically as cytotoxic agents against the brine shrimp lethality test (BST), in which compound 1 was found to be the most potent (LC50, 4.9 microg/mL). The antiplatelet activity of the methanolic extracts, the acidic fractions of aerial and root parts, and the identified compounds 1-3 were evaluated using an automatic platelet aggregometer and coagulation tracer (APACT 2). Using external reference standards, and a reverse-phase isocratic method, the distribution of aristolochic acid I and aristolochic acid II in different plant parts of Aristolochia maurorum L. during flowering stage was analyzed by PDA-HPLC. A quantitative comparison between two previously reported extraction methods was also made. Roots were found to be the main storage of aristolochic acid I and aristolochic acid II during flowering stage with about 0.22 and 0.108% (w/w), respectively.

Research Title: A Holystic Self-adaptive systems model
Author: Said Ahmad Ammar Ghoul, Published Year: 2021

Faculty: Information Technology
Abstract: The recent self-adaptive software systematic literature reviews stated clearly the following insufficiencies: (1) the need for a holistic self-adaptive software model to integrate its different aspects (2) The limitation of adaptations to context changes (3) The absence of a general and complete adaptations’ picture allowing its understandability, maintainability, evaluation, reuse, and variability. (4) The need for an explicit and a detailed link with resources, and (5) a usual limitation to known events.
In order to metigate these insufficiencies, this paper is proposing a holistic model that integrates the operating, adaptations, and adaptations’ manager aspects. The proposed model covers all possible adaptations: operating (dealing with software functions failures), lifecycle (handling adaptations required by some software lifecycle steps), and context (facing context changes events). The presented work introduces the concept of software adaptations process integrating the specifications of all the above kind of adaptations. In fact, this work shows an explicit trace to its pure bio-inspired origin.
An application of the proposed approach on a “car industry case study” demonstrated its feasibility in comparison with similar works that proved its meaningful added value and its promising research perspectives.

Faculty: Information Technology
Abstract: Most of Self-Adaptive Systems (SAS) use Feature Models (FMs) to represent their complex architecture and benefit from reusing commonalities and variability information. However triggering SAS reconfiguration process, each time a system needs to be adapted, continues to cost time and effort. Current FM techniques have modelled SAS concepts, focusing on representing and reusing elementary features without taking into consideration modelling and reusing configurations. This work presents an extension to the FM in order to remedy this important problem by introducing and managing the configuration feature. Evaluation shows that the reuse of configuration feature reduces reconfiguration process effort and time during the run time in order to meet the required scenario according to the context.

Research Title: Investigating the efficiency of financial markets: Empirical evidence from MENA countries
Author: Izzeddien Naef Ananzeh, Published Year: 2021
Investment management and financial innovations, Volume 18, Issue 1,
Faculty: Business
Abstract: The market efficiency hypothesis has become an important concept for all investors
looking to own internationally diversified portfolios, which coincides with an increase
in investment flows between all countries, both developed and undeveloped. This
study was aimed at investigating the efficiency of a group of Arab stock markets located
in the Middle East and North Africa (MENA) region according to the Random Walk
Hypotheses (RWH) at weak form. The study covered the markets of Jordan, Egypt,
Saudi Arabia, UAE, Bahrain, and Oman.
The empirical results of all tests used in this study rejected the RWH at a weak form for
all markets through all tests applied – Unit root test, Variance Ratio Test, and Run Test.
The result of this study contradicts the results of many studies conducted on developed
and emerging markets. This can be a good indication of the ineffectiveness of the reforms that have been adopted by responsible bodies on these markets.
Based on this result, all efforts made to expand and deepen these markets should be intensified by improving liquidity, transparency, enhancing investment culture in these
countries; supporting legislative and regulatory reforms to attract investment, and developing the financial sector in these markets as a whole.
Keywords: MENA markets, market efficiency, financial markets, unit root tests, run test, variance ratio test

Research Title: Expanding the phenotypic spectrum of FINCA (fibrosis, neurodegeneration, and cerebral angiomatosis) syndrome beyond infancy

Abstract: Fibrosis, neurodegeneration, and cerebral angiomatosis (FINCA, MIM#618278) is a
rare clinical condition caused by bi-allelic variants in NHL repeat containing protein 2
(NHLRC2, MIM*618277). Pulmonary disease may be the presenting sign and the few
patients reported so far, all deceased in early infancy. Exome sequencing was performed
on patients with childhood interstitial lung disease (chILD) and additional neurological
features. The chILD-EU register database and an in-house database were
searched for patients with NHLRC2 variants and clinical features overlapping FINCA
syndrome. Six patients from three families were identified with bi-allelic variants in
NHLRC2. Two of these children died before the age of two while four others survived
until childhood. Interstitial lung disease was pronounced in almost all patients during
infancy and stabilized over the course of the disease with neurodevelopmental delay
(NDD) evolving as the key clinical finding. We expand the phenotype of FINCA syndrome to a multisystem disorder with variable severity. FINCA syndrome should
also be considered in patients beyond infancy with NDD and a history of distinct
interstitial lung disease. Managing patients in registers for rare diseases helps identifying
new diagnostic entities and advancing care for these patients.
