Abstract
Purpose
This study aims to investigate the effect of leadership integrity on employees’ success. In this regard, the mediating role of ethical leadership and the moderating role of psychological capital and psychological empowerment were considered as well.
Design/methodology/approach
This study is an applied research and a descriptive-correlation survey that used quantitative data. Data were collected from 302 employees of a large factory in Iran who was selected randomly. The research questionnaire consisted of 54 statements and was distributed among the sample. Data was analyzed through confirmatory factor analysis and structural equation modeling.
Findings
The findings of this study show that leader integrity and ethical leadership have a positive effect on employees’ success and psychological capital and psychological empowerment moderate these effects. Moreover, leader integrity has an indirect effect on employees` success through employees’ perception of ethical leadership.
Originality/value
This study mainly contributes by explaining two sets of variables related to leaders’ behavior and employees’ cognitive competence which are complementary in improving employees’ potential success. The results highlight that leaders’ behavioral integrity can amplify ethical leadership which can ultimately leads to employees’ success if they have a high psychological empowerment and psychological capital.

Abstract
Purpose
The study investigates the effects of core self-evaluations on project managers' competencies. The study further examines the moderating effect of cultural intelligence between core self-evaluations and competencies.
Design/methodology/approach
In this study, with a descriptive-survey approach, necessary data were collected from a sample of project managers of Iran's Ministry of Communication and Information Technology through questionnaires. The conceptual framework of the study was tested according to structural equation modeling by PLS software.
Findings
Findings show that core self-evaluations have positive and significant effects on project managers' competencies among which psychological stability has the greatest effect. Furthermore, the moderating role of cultural intelligence in the relationship between core self-evaluations and project managers' competencies was confirmed. According to the calculated coefficient, motivational cultural intelligence had the greatest role.
Research limitations/implications
The data were collected using a questionnaire at a single point in time, and thus, not allowing cause–effect inferences. Also, the demographic variables were not controlled.
Practical implications
The results of this study provide some implications for HRM professionals and project managers interested in promoting a system of HR practices that contributes to enhancing project managers' competencies and effectiveness.
Originality/value
This study advances our understanding of the factors that have an effect on project managers' competencies, specifically on a list of main competencies necessary for project managers' performance. Moreover, it suggests that project managers' competencies will benefit from cultural intelligence, which will display a greater effect when embedded in highly diverse cultural contexts.

Abstract
Purpose
One of the recent applications of fabrics is to use them for sound insulation. Accordingly, due to their low production cost and low relative density, fabrics have drawn attention in some of the industries such as the automotive and aircraft industries. The present study is aimed to investigate the effects of the fiber cross-section, porosity, thickness of samples and fuzzing of the knitted fabric on the sound absorption coefficient.
Design/methodology/approach
In the present study, fabrics with three different stitch densities were knitted by yarns consist of three different forms of fiber cross-section shapes (circular, elliptical and plus-shaped). In this work, the sound absorption coefficient of knitted fabrics was investigated with regard to the different fiber cross-sections and structural parameters using an impedance tube.
Findings
As indicated by the obtained results, the cross-section, porosity, thickness and mass per unit area of the fabrics were the determinant factors for the sound absorption coefficient. In addition to, the sound absorption coefficient and porosity were shown to have an inverse relationship.
Originality/value
A section of the present paper has been allocated to the investigation of the effect of the fiber cross-section and fuzzing of fabric on the sound absorption of plain knitted fabrics.
