Abstract
Purpose
The purpose of this paper is to conceive a new surface texture incorporating a tiny shape among the micro-pockets (with circular, rectangular, trapezoidal and triangular cross-sections) and dimples (cylindrical, hemispherical and ellipsoidal) for exploring to enhance the maximum possible performance behaviors of sector shape pad thrust bearing.
Design/methodology/approach
Numerical simulation of hydrodynamically lubricated sector shape textured pad thrust bearing has been presented incorporating thermal and cavitation effects. The coupled solution of governing equations (Reynolds equation, film thickness expression, viscosity–temperature relation, energy equation and Laplace equation) has been achieved using finite difference method and Gauss–Seidel iterative scheme.
Findings
With new textured pads, higher load-carrying capacity and lower coefficient of friction are obtained in comparison to plain sector shape pad. Texture pattern comprising square cross-sectional pockets yields higher load-carrying capacity and lower coefficient of friction in comparison to other cross-sectional shapes (circular, trapezoidal and triangular) of pockets considered herein.
Originality/value
This study reports a new texture, which involves micro-pockets of square cross-sectional shapes to improve the performance behavior of sector shape pad thrust bearing. About 75 per cent increase in load carrying capacity and 42 per cent reduction in coefficient of friction have been achieved with pad having new texture in comparison to conventional pad.

Abstract
Purpose
The purpose of this paper is to understand the effect of store messiness and human crowding on shoppers' competitive behaviours, in-store hoarding and in-store hiding, through the mediating effect of perceived scarcity and perceived competition.
Design/methodology/approach
2 (store messiness: messy × tidy) × 2 (human crowding: high × low) between-subject factorial experiment was conducted online to manipulate retail store atmospheric factors. A total of 154 responses were collected through Amazon MTurk. The hypotheses were analysed using ANOVA and PROCESS (Hayes, 2013) procedure.
Findings
Results suggest that store messiness and human crowding within a fast-fashion store lead to perception of scarcity and competition that further affects competitive behaviours. When consumers experience store messiness, they are likely to hide merchandise in store, thus making it inaccessible for other consumers. Further, when they experience human crowding in the store, they feel that the products will be gone immediately so they have a tendency to hoard them.
Research limitations/implications
This study examined the effects of scarcity perception by studying the case of fast-fashion retailers; generalizability needs to be established across different contexts.
Practical implications
Retailers by manipulating human crowding and store messiness can create a perception of scarcity in their stores, thus enhancing sales. However, they should also pay attention to deviant behaviours such as in-store hoarding and in-store hiding as these behaviours may decrease the store sales.
Originality/value
This research contributed to the retailing literature by finding a significant relationship between human crowding, store messiness and competitive behaviours through perceived scarcity and competition.

Abstract
Purpose
The paper tries to investigate the impact of applications of the resource-based view (RBV) theory in the management field to improve the firm’s profitability. Global firms are innovating and adopting new technology, paving the way to improve their performance.
Design/methodology/approach
We have adopted RBV in management practices such as marketing, strategy, finance, and human resources.
Findings
RBV has gained researchers' attention with the growing competitive world and new challenges to retaining customers and achieving their pre-defined targets. We attempt to identify the issues related to the usage of RBV in management.
Originality/value
Using RBV in management may help researchers create a competitive mindset and be prepared for uncertain challenges in the business world.

Abstract
Since the spread of mass education around the world in the mid- to late-twentieth century, teacher quality has been heralded as the key factor to improve education quality nationwide. National education systems worldwide are also engaged in ongoing and often high stakes cross-national comparisons. As a result, policy-makers and educators in most national education systems are looking at and implementing new ways to improve education overall by raising teacher quality levels, and India is no exception. In India, teacher quality is publicly blamed for both perceived low education quality and demonstrated low average student performance, especially following Indian students’ performance on the 2009 Programme for International Student Assessment. Indian education policy-makers are, therefore, looking at teacher quality as a key factor to improve student performance. Little is known about the impact or implementation of Indian policy frameworks on teacher quality and associated student outcomes in India. This introductory chapter identifies and analyzes various measures of teacher quality and how teacher quality varies in India both in response to and in spite of national policies related to teacher quality. It begins by providing evidence regarding the global importance of teacher quality on student outcomes and then addresses the ambiguity of the term “teacher quality.” This chapter then briefly discussed national education policy in India and the role teacher quality has played in these national policies, especially in the early twenty-first century, including NCF 2005, NCFTE 2009, Draft NPE 2016, Draft NPE 2019, and NPE 2020.
