This study seeks to ascertain whether publicly listed Jordanian corporations (listed on the Amman Stock Exchange (ASE)) exhibit accounting conservatism and whether such companies distribute dividends to stockholders. Furthermore, this study delves into the implications of accounting conservatism on dividend policy in the context of the quality of financial statements of publicly listed Jordanian companies listed on the ASE. To accomplish the aims of this study, the Quality of financial reporting is treated as a moderator for the relationship between accounting conservatism and dividend distribution. Hence, a panel data approach was utilized, which encompasses cross-sectional data for 95 industrial and service establishments for the period (2013–2017). The study found that accounting conservatism has a negative impact on dividends and that there is no difference in the impact of accounting conservatism on dividends based on the quality of financial reports. The study concluded with a number of recommendations, the most salient of which is the need for companies to enhance their concentration on accounting conservatism and adopt a suitable policy for dividends. Thus, this research provides an insights into the financial practices of Jordanian publicly listed corporations and highlights the need for a more informed decision-making process concerning dividends and accounting practices.

In this article, the flexural and shear capacity of ultra-high-performance fiber-reinforced concrete beams (UHPFRC) using two kinds of rebars, including GFRP and steel rebars, are experimentally investigated. For this purpose, six UHPFRC beams (250 × 300 × 1650 mm) with three reinforcement ratios (ρ) of 0.64, 1.05, and 1.45 were constructed using 2% steel fibers by volume. Half of the specimens were made of UHPFRC reinforced with GFRP rebars, while the other half were reinforced with conventional steel rebars. All specimens were tested to failure in four-point bending. Both the load-deformation at mid-span and the failure pattern were studied. The results showed that utilizing GFRP bars increases the flexural strength of UHPFRC beams in comparison to those made of steel bars, but at the same time, it reduces the post-cracking strain hardening. Furthermore, by increasing the percentage of longitudinal bars, both the post-cracking strain hardening and load-bearing capacity increase. Comparing the experiment results with some of the available equations and provisions cited in the valid design codes reveals that some of the equations to predict the flexural strength of UHPFRC beams reinforced with conventional steel and GFRP bars are reasonably conservative, while Khalil and Tayfur model is un-conservative. This issue makes it essential to modify the presented equations in this research for predicting the flexural strength of UHPFRC beams using GFRP bars.

Objectives: Vesicular stomatitis virus (VSV) is under development as an oncolytic virus due to its preferential replication in cancer cells and oncolytic activity, however the viral components responsible have not yet been determined. In this study the effects of VSV wild-type (wt) and M51R-mutant matrix proteins (M51R-mMP) on apoptosis, pyroptosis, necroptosis, and autophagy pathways, in an esophagus cancer cell line (KYSE-30) were investigated. Methods: The KYSE-30 cells were transfected with pcDNA3.1 plasmids encoding wt or M51R-mMP, and apoptosis, pyroptosis, necroptosis, and autophagy were evaluated 48 and 72 hours after transfection. Results: KYSE-30 cells transfected with VSV wt and M51R-mMPs significantly reduced cell viability to < 50% at 72 hours post-transfection. M51R-MP significantly increased the concentration of caspase-8 and caspase-9 at 48 and 72 hours post-transfection, respectively (p < 0.05). In contrast, no significant changes were detected following transfection with the VSV wt plasmid. Moreover, VSV wt and M51RmMP transfected cells did not change the expression of caspase-3. VSV wt and M51R-mMPs did not change caspase-1 expression (a marker of pyroptosis) at 48 and 72 hours post-transfection. However, M51R-mMP and VSV wt transfected cells significantly increased RIP-1 (a marker of necroptosis) expression at 72 hours post-infection (p < 0.05). Beclin-1, a biomarker of autophagy, was also induced by transfection with VSV wt or M51R-mMPs at 48 hours post-transfection. Conclusion: The results in this study indicated that VSV exerts oncolytic activity in KYSE-30 tumor cells through different cell death pathways, suggesting that M51R-mMP may potentially be used to enhance oncolysis.

The structural behaviors of cylindrical barns as a specific engineering structure have been considered as a complicated computing process. The structure design against the earthquake load, to protect by using the code, is an urgency avoiding unexpected damages. The situation has been subjected to the applied design method if there would be no failure across the construction procedures. The purpose of the current study is to clarify the behaviors of cylindrical reinforced concrete barns through the analytic methods across the mass and Lagrangian approaches through the whole outcomes comparison indicating that the isoparametric element obtained from the Lagrangian approach has been successfully applied in the barns earthquake analysis when the slosh effects have been discarded. The form of stress distributions is equal with <i>s<sub>z</sub></i> closed distributions to one another.

Since the implementation of the disengagement plan in 2005, Israel has alleged that it no longer occupies the Gaza Strip and claimed its right to legitimate self-defence based on Article 51 of the United Nations Charter, including the suffocating blockade imposed there as well as the ‘Cast Lead’ military Operation and others. This paper analyzes Israeli’s claim in light of international law and the objective facts taking place in the Gaza Strip resulting from the implementation of the disengagement plan.

Evidence of the association between 25-hydroxyvitamin D (25(OH)D) and metabolic syndrome (MeS) remains uncertain and incongruent. This study aimed to determine the association between 25(OH)D and MeS among Jordanian adults. A complex multistage sampling technique was used to select a national population-based household sample. The present report deals exclusively with adults aged > 18 years who had complete information on all components of MeS (n = 3,234). A structured questionnaire was used to collect all relevant information. Anthropometric, clinical, and laboratory measurements were obtained. MeS was defined according to the International Diabetes Federation (IDF) definition. Of the total, 42.0% had MeS and 31.7% had 25(OH)D < 30 ng/ml. In a stratified analysis, the prevalence of MeS did not differ significantly between subjects with low and normal 25(OH)D levels for men and women in all age groups. In the multivariate analysis, the odds of MeS were not significantly different between subjects with low and normal 25(OH)D levels (OR = 0.85, 95% CI: 0.70, 1.05, P-value = 0.133). The association between 25(OH)D and MeS remained non-significant when 25(OH)D was analyzed as a continuous variable (OR = 1.004, 95% CI; 1.000, 1.008, P = 0.057) and when analyzed based on quartiles. None of the individual components of MeS were significantly associated with 25(OH)D level. This study does not provide evidence to support the association between 25(OH)D level and MeS or its individual components. Prospective studies are necessary to better determine the roles of 25(OH)D levels in the etiology of MeS.

Objective The aim of this systematic review and meta-analysis study was to determine the pooled estimate of the effect of antenatal magnesium sulfate (MgSO<sub>4</sub>) on intraventricular hemorrhage (IVH) in premature infants. Methods Two review authors independently searched all randomized clinical trials from international databases, including Medline (PubMed), Web of Sciences, Scopus, Cochrane Central Register of Controlled Trials (CENTRAL), and Research Registers of ongoing trials (ClinicalTrials.gov), from January 1989 to August 2017. Two independent review authors were responsible for data collection. After extracting the necessary information from the evaluated articles, metaanalysis of the data was performed using Stata version 14. Also, sources of heterogeneity among studies were determined by Meta regression. Results In this study, among 126 articles that were extracted from primary studies, 7 papers that evaluated the effect of MgSO<sub>4</sub> on IVH were eligible for inclusion in the meta-analysis. The results of the meta-analysis showed that pooled relative risk (95% confidence interval [CI]) was 0.80 (95% CI, 0.63 to 1.03) for the effect of MgSO<sub>4</sub> on IVH. Conclusion Results of this study showed that although MgSO<sub>4</sub> had a protective effect on IVH in premature infants, this effect was not statistically significant. Further studies are needed to determine the best dosage, timing, and gestational age to achieve the optimum effect of MgSO<sub>4</sub> on IVH.
Human Resource Management Practices and Employee Performance: The Role of Job Satisfaction
Yousef ALSAFADI,Shadi ALTAHAT 한국유통과학회 2021 The Journal of Asian Finance, Economics and Busine Vol.8 No.1
This study aims to investigate the impact of Human Resource Management Practices (HRMP) on improving Employee Performance (EP). The study is accomplished by hypothesizing the impact of HRMP on EP, additionally, this impact is theorized to be mediated through job satisfaction. Employee engagement is also taken into account because of the potential moderating effect it has within the theorized model. Data was collected from 480 questionnaires which were distributed among commercial banks’ workers in Jordan and were analyzed using structural equation modeling techniques (SEM), path analysis, and confirmatory factor analysis (CFA). Analysis of a moment structures (AMOS) software version 24 was applied to complete our analysis. The results show that HRMP had a positive impact on EP, as well as job satisfaction and its components (job stability and job enrichment). The mediating role of job satisfaction (enrichment and stability) was discovered. Finally, employee engagement emerged as a moderating variable linking HRMP and EP. The findings of this study show the importance of the role played by job satisfaction and employee engagement in achieving human resources performance goals. Future analysis is recommended to gain deeper insight into the relationship between HRMP, job satisfaction, worker training, and performance appraisal.
