This paper aims to study, the effects of opening shape, size and position as well as the aspect (height-to-length) ratio on the shear capacity, stiffness, ductility and energy dissipation capacity of triple-skin profiled steel-concrete composite shear wall (TSCSW) and investigate and compare them to those of concrete-stiffened steel plate shear walls (CSPSW). Two kinds of opening, circular and square, with different sizes and positions and two aspect ratios of 1:1 and 3:1 are considered in the simulations.

This study presents a novel TSCSW and compares its behavior with the existing CSPSW under the effect of monotonic and cyclic loadings. TSCSW is composed of three corrugated steel plates filled with concrete. The two external side plates are connected to the concrete core by means of several intermediate fasteners and the third one is an inner steel plate embedded within the concrete panel. The internal plate is a buckling restrained plate surrounded by concrete. This is the main superiority of TSCSW over other kinds of existing composite shear walls.

The results show that the shear capacity and the energy dissipation capacity of the proposed composite wall, TSCSW, are respectively about 16 and 12% higher than those of CSPSW when there is no opening. If an opening is considered in the wall, as the size of the opening is increased, the shear capacity, stiffness, ductility and absorbed energy of the two walls are decreased similarly. The destructive effect of square openings on the performance of the walls is more than that of circular openings.

The purpose of this paper is to study the effect of emotional quotient (EQ) on the organizational citizenship behavior (OCB) of some Iranian hospital staff in 2015. For this purpose, all hospital staff in Zahedan city were studied as the statistical population.

A randomized sampling method was used, and according to the Morgan Table, the statistical population was calculated as 346. This was a descriptive survey with a correlational and causative nature. Two questionnaires, namely, Bradbury and Graves’ Emotional Quotient and Podsakoff’s Organizational Citizenship Behavior, were used to collect the required information; they were distributed among the respondents after testing their validity and reliability. The people in the studied population were classified into classes that were homogeneous in terms of their properties.

The results of testing the hypotheses indicate that all the dimensions of EQ have a direct and significant effect on the emergence of OCB among the hospital staff in Zahedan. Finally, the results indicate the effect of EQ on OCB of the hospital staff.

Hospitals should consider emotional capabilities of the staff at the beginning of the employment period, and increase their sociability by inducting an atmosphere of organizational culture based on cooperation and empathy. It is suggested that a guideline of emotional eligibility and OCB be codified, which can influence job promotion and the promotion system. On specific occasions, hospital managers can honor the staff who have made positive and effective relationships in their career, and have achieved the satisfaction of their patients and colleagues by demonstrating extra-role behaviors. Thus, employees will be encouraged to continue this behavior and also provide a model to the staff. Through pre-service or in-service training classes and job seminars on the control of negative emotions and stresses while acquiring the skills of EQ, hospitals and other organizations can create OCB in the staff. As a result, visitor satisfaction would be gained, leading to better performance of hospitals.

It is suggested that a guideline of emotional eligibility and organizational citizenship behavior has to be codified which can affect the job promotion and promotion system. In specific occasions, the hospital managers can honor and pay tribute to the people who have made positive and effective relationships in their career, and have achieved the satisfaction of their patients and colleagues by showing extra-role behaviors.

This study used Data Envelopment Analysis (DEA) to measure and evaluate the operational efficiency of 26 isolation hospitals in Egypt during the COVID-19 pandemic, as well as identifying the most important inputs affecting their efficiency.

To measure the operational efficiency of isolation hospitals, this paper combined three interrelated methodologies including DEA, sensitivity analysis and Tobit regression, as well as three inputs (number of physicians, number of nurses and number of beds) and three outputs (number of infections, number of recoveries and number of deaths). Available data were analyzed through R v.4.0.1 software to achieve the study purpose.

Based on DEA analysis, out of 26 isolation hospitals, only 4 were found efficient according to CCR model and 12 out of 26 hospitals achieved efficiency under the BCC model, Tobit regression results confirmed that the number of nurses and the number of beds are common factors impacted the operational efficiency of isolation hospitals, while the number of physicians had no significant effect on efficiency.

The limits of this study related to measuring the operational efficiency of isolation hospitals in Egypt considering the available data for the period from February to August 2020. DEA analysis can also be an important benchmarking tool for measuring the operational efficiency of isolation hospitals, for identifying their ability to utilize and allocate their resources in an optimal manner (Demand vs Capacity Dilemma), which in turn, encountering this pandemic and protect citizens' health.

Despite the intensity of studies that dealt with measuring hospital efficiency, this study to the best of our knowledge is one of the first attempts to measure the efficiency of hospitals in Egypt in times of health' crisis, especially, during the COVID-19 pandemic, to identify the best allocation of resources to achieve the highest level of efficiency during this pandemic.
