Ownership structure’s effect on financial performance : an empirical analysis of Jordanian listed firms

This study aims to examine the impact of the ownership structure on firm performance in the Jordan. This study employed the multiple-regression model and fixed regression effect to analyse the data. The sample included all Jordanian first market firms listed on the Amman Stock Exchange (ASE) from 2012 to 2018. The paper’s findings reveal a positive and significant relationship between institutional ownership and both accounting measure Return on Assets (ROA) and market measure Tobin’s Q (TQ). Other ownership structure types, such as concentration of ownership, also affect ROA and TQ. While managerial ownership shows a negative relationship with ROA, but there is no association with TQ. This study has broad and comprehensive practical implications that are good for policymakers. On the one hand, it adds to the debate on agency theory from the ownership structure and firm’s performance relationship. On the other hand, it helps the Jordanian Government formulate policies and regulations to strengthen corporate governance (CG), which increases the interests of all stakeholders in the Jordanian market

The antimicrobial properties of copper surfaces against a range of important nosocomial pathogens

Hospital acquired infections (HAI) are a major problem worldwide and controlling the spread of these infections within a hospital is a constant challenge, Recent studies have highlighted the antimicrobial properties of copper and its alloys against a range of different bacteria. The objective of this study was to evaluate the antimicrobial properties of copper compared to stainless steel against a range of clinically important pathogens. These pathogens consisted of five isolates of each of the following organisms; meticillin resistant Staphylococcus aureus (MRSA), Pseudomonas aeruginosa, Escherichia coli, vancomycin-resistant Enterococci (VRE) and Panton-Valentine Leukocidin positive community acquired-MSSA (PVL positive CA-MSSA). MRSA, A aeruginosa, E. coli, and CA-MSSA isolates were not detectable after a median time of 60 minutes. No detectable levels for all VRE isolates were determined after a median time of 40 minutes. However, for all isolates tested the stainless steel had no effect on the survival of the bacteria and levels remained similar to the time zero count.. The results of this study demonstrate that copper has a strong antimicrobial effect against a range of clinically important pathogens compared to stainless steel and potentially could be employed to aid the control HAI
