Humility: An Emerging Construct in Moral Psychology

The virtue of humility is lauded by most authorities but opinions of what it is, what it includes and what it does not are multifarious. Religious and philosophical traditions in India stress its role in emancipating the ego and providing an understanding for one’s perspective as contrasted against the magnanimity of the Almighty, the Supernatural or the Universe. Most academicians within the scientific psychological realm also look upon humility as a virtue. Accredited as a powerful tool for personal, social and organisational well-being, humility, as a moral construct, deserves a thorough and detailed exploration to reveal what it entails, what its corollaries are and how it can be measured. It is particularly useful in Indian context, as indigenous traditions have always emphasised humility. However, such efforts have remained relatively neglected till recent years. Of course, a few researchers with emphasis on moral and positive psychology have probed and prodded this concept to lay bare its comprising elements and to build tools to measure it. These attempts have been discussed here. Information was culled from surveying the scientific literature of the past four decades from psychological and philosophical journals and handbooks. Its overlap with Indian concept of humility has been discussed, and the unresolved questions about its nuances are put forward for future research endeavour.     

Subordinate Performance, Leader-Subordinate Compatibility, and Exchange Quality in Leader-Member Dyads: A Field Study

A model examining factors related to quality of exchange in leader-member dyads was developed and tested. Subordinates and supervisors in 223 dyads in a manufacturing setting provided demographic data and completed measures of performance and attitude towards work. Results found organization citizenship behaviors, leader-member attitude similarity, and similarity of education to be related to quality of leader-member exchange.     

Enhanced embodied response following ambiguous emotional processing

It has generally been assumed that high-level cognitive and emotional processes are based on amodal conceptual information. In contrast, however, "embodied simulation" theory states that the perception of an emotional signal can trigger a simulation of the related state in the motor, somatosensory, and affective systems. To study the effect of social context on the mimicry effect predicted by the "embodied simulation" theory, we recorded the electromyographic (EMG) activity of participants when looking at emotional facial expressions. We observed an increase in embodied responses when the participants were exposed to a context involving social valence before seeing the emotional facial expressions. An examination of the dynamic EMG activity induced by two socially relevant emotional expressions (namely joy and anger) revealed enhanced EMG responses of the facial muscles associated with the related social prime (either positive or negative). These results are discussed within the general framework of embodiment theory.

On the synthesis and characterisation of novel composite-structured high-entropy alloys

A study of novel composite-structured CoCrFeNi₃Si, CoCrFe₂Ni₂Si and Co₂CrFeNi₂Si high-entropy alloys, synthesised by vacuum arc melting, is presented. The designing criteria for the formation of such alloys were based on the enthalpy of mixing and the valence electron concentration. X-ray diffraction analysis revealed that all the alloys were composed of face-centered cubic and intermetallic phases. Scanning electron microscopy, along with elemental analysis, indicated that the face-centered cubic phase mainly contains Co, Cr, Fe and Ni, whereas, the intermetallic compound is Ni-Si rich. All the synthesised high-entropy alloys in the present investigation possess excellent compressive strength along with ductility at room temperature, suggesting significant potential application in the engineering field. Furthermore, enhanced hardness, wear resistance and corrosion resistance were achieved in all the designed high-entropy alloys. The previously given design parameters for the composite-structured high-entropy alloys are in good accord with the current research work.     

Marital Quality and Gender Role Stereotype

The study explored the relation of marital quality with gender role stereotype. A cohort of 350 couples aged 30–50 years were assessed for marital quality, gender role identity and gender role attitude. Results revealed a preference for traditional pattern, as masculinity for men and femininity for women were associated with better marital quality. Modern gender role attitude was significantly associated with marital quality in case of non-working women, but not with other categories. The results have been discussed in the context of cultural notions of gender.
