The Effect of Ethics-Oriented Leadership and Political Skills of Digital Organizational Developments on Accounting Students' Perceptions

Purpose: The purpose of this study was to investigate the effect of ethics-oriented leadership and political skills of digital organizational developments on accounting students' perceptions. Method: The study population in this study was accounting students in Shiraz. The statistical population of this study includes all accounting students in Shiraz, whose number is 850 people. The number of samples was 265 based on the Morgan table. 400 questionnaires were distributed electronically and randomly and 265 questionnaires were selected. After data collection, structural equations were analyzed using SPSS and SMART PLS software. Findings: Based on the results, ethical leadership has a positive and significant relationship with accounting students' perception of leadership effectiveness. Political skills have a negative and significant relationship with accounting students' perception of leadership effectiveness. Machiavellianism mediates the role of leadership in the relationship between ethical leadership and accounting students' perceptions of leadership effectiveness. Machiavellianism has an increasing mediating role in political skills and accounting students' perceptions of leadership effectiveness. Conclusion: This article is practical. Therefore, its main contribution is to clarify the discussion about the impact of digital transformation in the accounting sector and the importance of accounting ethics in the digital age. Nevertheless, the results can be interesting for researchers, policymakers, teachers, professional institutions, and accounting professionals

Neurologic complications in percutaneous nephrolithotomy

Percutaneous nephrolithotomy (PCNL) has been the preferred procedure for the removal of large renal stones in Iran since 1990. Recently, we encountered a series of devastating neurologic complications during PCNL, including paraplegia and hemiplegia. There are several reports of neurologic complications following PCNL owing to paradoxical air emboli, but there are no reports of paraplegia following PCNL. Materials and Methods: We retrospectively reviewed the medical records of patients who had undergone PCNL in 13 different endourologic centers and retrieved data related to neurologic complications after PCNL, including coma, paraplegia, hemiplegia, and quadriplegia. Results: The total number of PCNL procedures in these 13 centers was 30,666. Among these procedures, 11 cases were complicated by neurologic events, and four of these cases experienced paraplegia. All events happened with the patient in the prone position with the use of general anesthesia and in the presence of air injection. There were no reports of neurologic complications in PCNL procedures performed with the patient under general anesthesia and in the prone position and with contrast injection. Conclusions: It can be assumed that using room air to opacify the collecting system played a major role in the occurrence of these complications. Likewise, the prone position and general anesthesia may predispose to these events in the presence of air injectio

Ureteroscopic lithotripsy compared with extracorporeal shockwave lithotripsy in the treatment of urolithiasis

Introduction: Urolithiasis is a common and frequently occurring disease with high recurrence rate. Ureteroscopic lithotripsy (URSL) and extracorporeal shock wave lithotripsy (ESWL) are two most popular modalities in the treatment of urolithiasis. The efficacy of these two methods is reviewed on the treatment of ureteral stones in this systematic review. Method: PubMed was searched for the relevant randomized control trials (RCTs). Stone-free rate and retreatment rate were extracted from each article as the main outcomes, and Odds ratio was reported in each study.Result: Based on calculated odds ratio of each article, URSL has an odds ratio of 1 for the event of retreatment rate compared with ESWL.Discussion: Performing URSL in the treatment of urolithiasis could be associated with higher stone-free rate and lower retreatment rate; however duration of the surgery seems to be longer during URSL compared with ESWL.Conclusions: There was high discrepancy between included RCTs regarding the study design, stone location, types of ureteroscope, intracorporeal lithotripsy devices, time to follow-up, and surgeon experience, which might affect the decision regarding type of surgery

Spray Deposited Nanostructured CuO Thin Films: Influence of Substrate Temperature and Annealing Process

<div><p>In this study, CuO thin films were deposited on glass substrates at a wide range of temperatures from 450ºC to 550ºC with steps of 25ºC by chemical spray pyrolysis technique. Aiming to investigate the effect of annealing process, one of the resulting films was annealed at 450ºC for 3 hours under ambient air. Based on X-ray diffraction, all the resulting films are monoclinic with two prominent peaks at ~36º and ~39º. The crystallite size of the CuO film deposited at 450ºC was found to be the largest in comparison with the others. As the substrate temperature increased, a gradual change was observed for the CuO thin film surface morphology and in the case of annealed film, the grains and their boundaries became indistinguishable. The resistivity of the films was reduced by virtue of increasing the substrate temperature and also, both the mobility and carrier concentration of the annealed film were improved drastically after annealing. As expected, the CuO thin films absorption was considerable in the visible region and gradually declined after 800nm. The estimated band gap value of the CuO film deposited at 450ºC were fairly close to the optimum band gap for solar applications.</p></div

Keywords Extracorporeal shockwave lithotripsy Ureteroscopic surgery Urolithiasis Introduction: Urolithiasis is a common and frequently occurring disease with high recurrence rate. Ureteroscopic lithotripsy (URSL) and extracorporeal shock wave lithotripsy (ESWL) are two most popular modalities in the treatment of urolithiasis. The efficacy of these two methods is reviewed on the treatment of ureteral stones in this systematic review. Method: PubMed was searched for the relevant randomized control trials (RCTs). Stone-free rate and retreatment rate were extracted from each article as the main outcomes, and Odds ratio was reported in each study. Result: Based on calculated odds ratio of each article, URSL has an odds ratio of &lt;1 for the event of stone-free rate, and odds ratio of &gt;1 for the event of retreatment rate compared with ESWL. Discussion: Performing URSL in the treatment of urolithiasis could be associated with higher stone-free rate and lower retreatment rate; however duration of the surgery seems to be longer during URSL compared with ESWL. Conclusions: There was high discrepancy between included RCTs regarding the study design, stone location, types of ureteroscope, intracorporeal lithotripsy devices, time to follow-up, and surgeon experience, which might affect the decision regarding type of surgery.
