Purpose The purpose of this paper is to investigate the perceptions of faculty members about the influence of family motivation on their self-efficacy and organizational citizenship behavior-individual (OCBI). Design/methodology/approach The proposed model was tested on a sample of 353 faculty members from different public and private universities of Pakistan. Partial least squares structural equation modeling was used to analyze data. Findings Surprisingly, results reveal that family motivation was not positively related to faculty members’ OCBI; instead, this relationship is fully mediated by self-efficacy. The findings suggest that it is employees’ self-efficacy belief through which their family motivation translates to their increased OCBI. This study also finds that supporting the family is a powerful source of motivation to work, offering meaningful practical and theoretical implications for policy-makers, leaders, managers and researchers on the new dynamics of work and family engagements. Originality/value The study contributes to human resource management (HRM) and organizational behavior (OB) literatures by providing some useful practical implications for managers and HRM and OB consultants who are interested in understanding the underlying psychological mechanisms (i.e. self-efficacy) through which employees’ family motivation results in the increased OCBI.

We have theoretically demonstrated an efficient way to improve the optical properties of an anti-reflection coating (ARC) and an intermediate reflective layer (IRL) to enhance tandem solar cell efficiency by localizing the incident photons’ energy on a suitable sub-cell. The optimum designed ARC from a one-dimensional ternary photonic crystal, consisting of a layer of silicon oxynitride (SiON), was immersed between two layers of (SiO2); thicknesses were chosen to be 98 nm, 48 nm, and 8 nm, respectively. The numerical results show the interesting transmission properties of the anti-reflection coating on the viable and near IR spectrum. The IRL was designed from one-dimensional binary photonic crystals and the constituent materials are Bi4Ge3O12 and μc-SiOx: H with refractive indexes was 2.05, and 2.8, respectively. The numbers of periods were set to 10. Thicknesses: d1 = 62 nm and d2 = 40 nm created a photonic bandgap (PBG) in the range of [420 nm: 540 nm]. By increasing the second material thickness to 55 nm, and 73 nm, the PBG shifted to longer wavelengths: [520 nm: 630 nm], and [620 nm: 730 nm], respectively. Thus, by stacking the three remaining structures, the PBG widened and extended from 400 nm to 730 nm. The current theoretical and simulation methods are based on the fundamentals of the transfer matrix method and finite difference time domain method.
