Purpose – The purpose of this paper is to investigate the vital determinants on the extent of corporate social responsibility (CSR) disclosure in a US context. The selected variables are CEO duality, the presence of women in the board, greenhouse gas (GHG) emissions, emission reduction initiatives, company's risk premium, financial leverage and industry's profile. Design/methodology/approach – The environmental, social and governance (ESG) disclosure score is used as a proxy for the extent of CSR disclosure calculated by Bloomberg. The influence of plausible variables on the ESG disclosure score and its sub-categories was examined by using the least squares dummy variable model (LSDV) incorporating 100 companies listed on Standard & Poor's 500 Index for the period 2009-2012. Findings – The results show that the emission reduction initiatives and GHG emissions influence positively the extent of ESG score. In addition, slight differences exist concerning the determinants of different types of disclosures. Furthermore, it is illustrated that a company's industrial profile seems to have differences among the extent of the different types of disclosure. Research limitations/implications – The sample of companies is based on the US companies incorporating only large-sized ones. Originality/value – The study extends previous studies with the inclusion of both traditional and innovative determinants of the CSR disclosure in USA taking into account four years of corporate data. A third party rating approach was adopted in order to calculate the extent of CSR disclosure. Finally, both the shareholders’ and the investors’ attitudes in relation to CSR disclosure are presented.

Purpose The purpose of this study is to investigate the effect of environmental performance on the environmental disclosure level. Design/methodology/approach Carbon disclosure leadership index score is considered as a proxy of carbon disclosure level, while greenhouse gas (GHG) emissions as a proxy of environmental performance. In addition, six control variables are used: return on assets, financial leverage, company’s size, CEO duality, board size and percentage of independent directors on board. The sample comprises 102 companies from a population of Standard & Poor’s 500 (S&P 500) companies over a five-year period, 2009-2013. Findings Results revealed that higher pollution levels in terms of GHG emissions affect negatively the dissemination of carbon disclosure information, suggesting a positive relationship between environmental performance and environmental disclosure level. In addition, companies with good environmental performance in relation to their average environmental performance disseminate more carbon information in their disclosures. Thus, the carbon disclosure level is indicative of environmental performance consistent with the voluntary disclosure theory. Practical implications The managerial behavior regarding the relation of environmental disclosure and environmental performance is explained. In addition, the findings should be of use to those investors interested in finding carbon emission information so that they assess investments and evaluate their current portfolios in terms of environmental sustainability. Originality/value It is intended to ascertain the reliability level of carbon disclosure regarding carbon emission information by incorporating the carbon disclosure leadership index score and GHG emissions.

This study investigates whether corporate social responsibility (CSR) affects the financial performance of the United States (US) companies. In particular, the impact of CSR on financial performance is investigated in terms of involvement in socially responsible initiatives instead of outcome. The Environmental, Social and Governance disclosure score as calculated by Bloomberg is used as a proxy for corporate involvement in socially responsible initiatives. Fixed effects regression is employed to estimate the relationship between the extent of corporate social disclosure (CSD) and financial performance using the data of listed companies on the Standard & Poor's 500 during the period 2009-2013. The results suggest that the involvement in socially responsible initiatives has a significantly positive effect on financial performance. In addition, the control variables, such as total compensation to directors, CEO duality and women presence on board are statistically significant to financial performance. It is important to incorporate a longer period in order to validate the positive relationship between CSR and financial performance, whilst the sample is focused on large in size US companies. This study chose to approach the topic from a different angle in order to provide an alternate perspective on this issue taking into account the involvement of socially responsible initiatives via CSD.

The COVID-19 pandemic led universities to transform the traditional teaching methodologies into distance education. Therefore, social media has become progressively prominent as teaching and learning resources in universities. Several studies have been conducted for the development of social media as a learning tool. However, there is limited empirical evidence supporting this claim. The present study bridges the gap in the literature concerning the value of the use of social media in higher education. This research seeks to examine the impact of the use of social media in (a) enhancing teaching and learning in universities, (b) motivating and supporting students and (c) developing community connection. A qualitative methodology was adopted. Specifically, in-depth interviews were conducted to assess the effectiveness of social media on students learning in higher education. The results showed that the use of social media by higher educational institutions positively impacts the educational process by (a) promoting teaching and learning, (b) motivating students to be active participants, and (c) establishing connections in the university community. Some obstacles in the teaching and learning process were also identified. Future areas of research are proposed.
