Human resource (HR) disclosures are voluntary in nature in most countries including India. The voluntary nature of HR disclosures results in discrepancy in the HR disclosure practices across companies and industries. The purpose of this paper is to examine the extent of HR disclosures in annual reports of Indian listed companies and to identify their determinants in a three stage analysis.

In the first stage a 16 item human resource disclosure index (HRDI) has been constructed for the set of CNX 200 companies listed on National Stock Exchange. Thereafter the effect of various independent variables on HRDI is analysed descriptively. Finally in the third stage HRDI has been regressed against the independent variables using regression analysis technique to identify key determinants of HRDI.

The research reveals that there is high variation among sample companies as regard HRDI. The results of descriptive analysis, correlation analysis and multivariate regression analysis establish that government’s participation in ownership and market capitalisation has positive significant effect on HRDI at 1 per cent, presence of separate HR directors committee, presence of more independent directors on board at 5 per cent and cross-list America and profit after tax at 10 per cent level. Implicitly HRDI is positively affected by size of company as measured by market capitalisation. Though contrary to expectations, other variables leverage, number of employees, assets, ownership concentration, type of auditor, age, complexity of business structure, employee expense to total operating expense ratio, industry affiliation, foreign investment and proportion of non-executive directors on board are found to have moderate though insignificant influence on HRDI.

Cross-sectional design, dependence on annual reports as a primary document for disclosure and subjectivity in HRDI construction are the main limitations of the research. A longitudinal study may be carried to study the pattern of HR disclosures in future. Weighted ranking of different items of disclosures may be studied to improve the understanding of extent of disclosures.

The HRDI as constructed in the research may be used as a benchmark by companies to improve their HR disclosures. It can also be used by accounting bodies and company regulators while deciding about standards regarding HR disclosures. Investors can also use HR disclosures made by a company as a basis to understand its financial standing and future potentials.

The study adds to the existing literature by developing 16 item HRDI to measure the extent of disclosures by listed companies in India and thereafter by including some new propositions in the determinants of HRDI have never been tested in the existing studies. These propositions are government’s participation in ownership, separate HR committee of directors, board composition and foreign activity. These propositions have been empirically validated in this research except for foreign activity.

The United Nations has demonstrated a commitment to preserving the ecosystem through its 2030 sustainable development goals agenda. One crucial objective of these goals is to promote a healthy ecosystem and discourage practices that harm it. Building materials production significantly contributes to the emissions of greenhouse gases. This poses a threat to the ecosystem and prompts a growing demand for sustainable building materials (SBMs). The purpose of this study is to investigate SBMs to determine their utilization in construction operations and the potential impact their application could have on construction productivity.

A systematic review of the existing literature in the field of SBMs was conducted for the study. The search strings used were “sustainable” AND (“building” OR “construction”) AND “materials” AND “productivity”. A total of 146 articles were obtained from the Scopus database and reviewed.

Bio-based, cementitious and phase change materials were the main categories of SBMs. Materials in these categories have the potential to substantially contribute to sustainability in the construction sector. However, challenges such as availability, cost, expertise, awareness, social acceptance and resistance to innovation must be addressed to promote the increased utilization of SBMs and enhance construction productivity.

Many studies have explored SBMs, but there is a dearth of studies that address productivity in the context of SBMs, which leaves a gap in understanding. This study addresses this gap by drawing on existing studies to determine the potential implications that using SBMs could have on construction productivity.

The purpose of this paper is to design a low-cost stress bimorph RF-MEMS switch which is the desired transmission area application.

The bimorph structure of the low-temperature plasma-enhanced chemical vapor deposition (PECVD) of thermal oxide and gold are utilized to create the vibrating membrane. The effects of process conditions of low-temperature oxide deposited using the PECVD technique enable stress-free deposition of the key structural layer.

Scanning electron microscope images of the RF micro-switch confirms negligible stress in the released structure. The RF performances of this device exhibit isolation around 43 dB of up to 50 GHz in the OFF-state position and an insertion loss of less than 0.18 dB in the ON-state.

The finite element method results show good isolation of 43 dB and less insertion loss of 0.18 dB.
