Abstract
Purpose
This paper aims to report on the experiments with the Contour Crafting Automated Construction process using sulfur concrete as the choice of construction material.
Design/methodology/approach
Several experiments have been performed at centimeter and meter scales. A finite element analysis simulation model for the behavior of sulfur concrete-based structures has been developed. Experimental results were compared with the results of simulation.
Findings
Sulfur concrete has numerous terrestrial applications and is potentially an ideal construction material for planetary construction.
Originality/value
Experimental samples of sulfur concrete were fabricated using a novel mixer/extrusion system. The mechanism was proven to be durable and stable after more than 500 h of work.

Abstract
Purpose
The purpose of this study is to evaluate the impact of psychological entitlement and perceived organizational justice on cyberloafing.
Design/methodology/approach
In this study, a cross-sectional research design based on a questionnaire method was used to collect the required data from a sample of 226 employees working at selected universities in the city of Isfahan, Iran. To test the research hypotheses, structural equation modeling was used.
Findings
According to the findings, psychological entitlement could have a significant impact on perceived organizational justice and consequently perceived organizational justice could significantly influence cyberloafing. Moreover, psychological entitlement could significantly influence cyberloafing and finally, psychological entitlement could have a significant effect on cyberloafing through perceived organizational justice.
Originality/value
This research provides valuable insight for studying the relationship among psychological entitlement, perceived organizational justice and cyberloafing.
