Abstract

Purpose

The purpose of this paper is to comprehensively analyze the corporate social responsibility (CSR) and sustainability reporting (SR) practices of Indian companies in terms of disclosure quantity and quality, and to investigate the differences in SR practices by SR dimension, industry, ownership structure, firm size and profitability.

Design/methodology/approach

Data are collected from annual reports/business responsibility reports (BRR)/CSR/sustainability reports of 60 top-listed companies in India. A comprehensive sustainability reporting index is developed. Content analysis technique is used. Inter-coder reliability is established.

Findings

Altogether, 18 items of the index are not disclosed by the majority of companies in India. SR quality is found significantly lower than the SR quantity. Moreover, SR practices significantly differ by dimension/category, industry-type and firm-size but are not influenced by ownership structure. However, the study fails to establish any conclusive relationship between SR and profitability.

Practical implications

The present study has several implications for corporates, practitioners, policymakers and stakeholders. The findings underscore the need for amendments in the Global Reporting Initiative guidelines and BRR framework of the Securities and Exchange Board of India to avoid patchy disclosures and ensure complete reporting by companies.

Originality/value

This study is among the foremost studies in India evaluating SR practices of top-listed companies in the wake of the mandatory BRR requirement from a quantitative as well as qualitative perspective using a multidimensional index.

Abstract

Purpose

This paper aims to investigate the eco-friendly neodymium tartrate (NdTar) inhibitor for mild steel in sodium chloride (NaCl) solution.

Design/methodology/approach

The mild steel 1010 coupon was considered for the current study. Weight loss and the electrochemical methods were used to evaluate the inhibitory effects of neodymium chloride (NdCl3) and NdTar on mild steel in NaCl solution. Scanning electron microscopy, energy-dispersive X-ray analysis and attenuated total reflectance-Fourier transform infrared spectroscopy measurements were carried out to study the morphology and composition of the film, nature of deposits and corrosion products formed in test media on the corroded steel, with the objective of further analyzing the observed behavior of the two inhibitors.

Findings

Of the two, NdTar performs better than NdCl3 because it shields mild steel surfaces for longer. According to the results, when NdCl3 is present in a corrosive solution, the protective film only comprises Nd/Fe oxide/hydroxide/carbonate. However, when neodymium is coupled with the tartrate group (an organic group) and then added to the NaCl solution, the inhibitor film comprises both bimetallic complexes (Fe-Tar-Nd) and metal oxide/hydroxide/carbonate, which results in a more compact film and has higher inhibition efficiency.

Originality/value

This study evaluated the combined effects of inorganic and organic inhibitors with those of an inorganic inhibitor used alone for mild steel in NaCl solution.

Abstract

Purpose

This study aims to develop a compact analytical models for undoped symmetric double-gate MOSFET based on carrier approach. Double-Gate (DG) MOSFET is a newly emerging device that can potentially further scale down CMOS technology owing to its excellent control of short channel effects, ideal subthreshold slope and free dopant-associated fluctuation effects. DG MOSFET is of two types: the symmetric DG MOSFET with two gates of identical work functions and asymmetric DG MOSFET with two gates of different work functions. To fully exploit the benefits of DG MOSFETs, the body of DG MOSFETs is usually undoped because the undoped body greatly reduces source and drain junction capacitances, which enhances the switching speed. Highly accurate and compact models, which are at the same time computationally efficient, are required for proper modeling of DG MOSFETs.

Design/methodology/approach

This paper presents a carrier-based approach to develop a compact analytical model for the channel potential, threshold voltage and drain current of a long channel undoped symmetric DG MOSFETs. The formulation starts from a solution of the 2-D Poisson’s equation in which mobile charge term has been included. The 2-D Poisson’s equation in rectangular coordinate system has been solved by splitting the total potential into long-channel (1-D Poisson’s equation) and short-channel components (remnant 2-D differential equation) in accordance to the device physics. The analytical model of the channel potential has been derived using Boltzmann’s statistics and carrier-based approach.

Findings

It is shown that the metal gate suppresses the center potential more than the poly gate. The threshold voltage increases with increasing metal work function. The results of the proposed models have been validated against the Technology Computer Aided Design simulation results with close agreement.

Originality/value

Compact Analytical models for undoped symmetric double gate MOSFETs.

Abstract

Purpose

The purpose of this study is to investigate microbial influenced corrosion of steel because of iron oxidizing bacteria (IOB).

Design/methodology/approach

Carbon steel was selected for this study. Winogradsky media was used for isolation of IOB and as test solution for corrosion measurements. Electrochemical tests and immersion test were conducted to estimate the corrosion rate and extent of pitting. The corroded surface was analysed by SEM and corrosion products formed over the metal surface were identified by XRD and Fourier transformed infrared. Biofilm formed over the corroded metal was analysed by UV-visible spectroscopy for its extracellular polymeric substances (EPS) constituents.

Findings

Presence of IOB in Winogradsky medium enhances corrosion. Uniform and localized corrosion increases with increased bacterial concentration and EPS constituents of the biofilm. Iron sulphite formation as one of the corrosion products has been suggested to be responsible for increased corrosion attack in the inoculated media in comparison to control media where corrosion product observed is iron hydrogen phosphate which is protective in nature.

Originality/value

This work correlates increased corrosion of steel in the presence of bacteria with the nature of corrosion products formed over it in case of IOB. Formation of corrosion products is governed by various electrochemical reactions; hence, inhibition of such reactions may lead to reduce or stop the formation of such products which enhances corrosion and thereby may reduce the extent of microbial induced corrosion.

Abstract

Purpose

Low power static‐random access memories (SRAM) has become a critical component in modern VLSI systems. In cells, the bit‐lines are the most power consuming components because of larger power dissipation in driving long bit‐line with large capacitance. The cache write consumes considerable large power due to full voltage swing on the bit‐line. The aim of the paper is to propose a new SRAM cell architecture to reduce the power consumption during write 0 and write 1 operation.

Design/methodology/approach

The proposed circuit includes two tail transistors in the pull‐down path of inv‐A and inv‐B. The simulated results of the proposed cell is compared with Conventional 6T SRAM cell and zero‐asymmetric SRAM cell.

Findings

The proposed SRAM cell consumes less power than the conventional SRAM cell during write operation. The write access delay is reported to be lower than conventional and ZA SRAMs in the proposed circuit. The read operation is similar to Conventional SRAM cell but due to tail transistors the read access delay and stability is poor in the present circuit which can be improved by careful transistors sizing.

Originality/value

The paper proposes a SRAM cell to reduce the power in write “0” as well as write “1”operation by introducing two tail transistors.

Abstract

Purpose

The purpose of this paper is to identify the impact of organizational stressors on organizational citizenship behaviour (OCB) and how perceived organizational support (POS) will moderate in the relationship between stressors and citizenship behavior.

Design/methodology/approach

The sample for this research involves operators from call center organizations located around the national capital of India. A questionnaire survey was carried out involving 402 operator level employees from five different organizations.

Findings

The results highlight a significant negative relationship between organizational stressors and OCB, a significant positive relationship between POS and OCB, and confirmation that POS moderates in the relationship between organizational stressors and OCB.

Research limitations/implications

This research has been carried out in an emerging economy and in a sector which is seen as an attractive area of work. However, as this study is limited to the BPO sector in India, these results may not be generalized to other areas such as the public and manufacturing sectors and in other national contexts. Future research in this area should also consider using different data collection approaches to maximize participation and enrich findings.

Practical implications

The analysis suggests that change management initiatives in organizations may not be implemented as effectively as they can under high stressor conditions because employee extra‐role work behavior and commitment may not be at full capacity.

Originality/value

There is limited research examining the relationship between organizational stressors and OCB in the presence of POS, especially within high demand environments such as the Indian BPO sector.
