The effects of board composition on performance have long been discussed in management research using fractionalization measures. In this study, we propose an alternative measurement approach based on board polarization.

Using an exploratory analysis and applying the polarization measure to German Deutscher Aktienindex (DAX)-, Midcap-DAX (MDAX)- and Small Cap-Index (SDAX)-listed companies, this paper applies the polarization index to examine the relationship between board diversity and performance.

The results show that the polarization concept is well suited to measure principal-agent problems between the members of the management and supervisory boards. We reveal that board polarization is negatively associated with firm performance, as measured by return on investment (ROI).

This exploratory study shows that the measurement of board polarization can be linked to performance differences between companies, which offers promising starting points for further research.

This study aims to examine the influence of brand awareness on brand equity with the mediating role of brand association and perceived quality.

This research is applied in terms of the objective and descriptive survey in terms of methodology because its objective is to describe the studied conditions or phenomena and also the relationship between research variables that have been conducted in the field method.

The results explained that 53% of respondents are female and 47% of respondents are male. Most respondents are between 30 and 40 years old, and the youngest respondents are less than 30 years old. Most respondents were specialists, and the 134 respondents were subspecialists. The results explained that the significance level of the Kolmogorov–Smirnov test for research variables is less than 0.05 and has an abnormal distribution. The abnormality of the data in this study directed the authors to use PLS software to analyze the data.

To the best of the authors’ knowledge, it is the first time that research is prepared to study the impact of these marketing parameters on dentists’ prescription behavior.

Electric Vehicles (EVs), owing to their low carbon emissions, have gained immense importance in achieving net-zero emissions by 2070. They have also appeared as viable substitute to conventional vehicles. Aligning with global initiatives, India has created a favourable ecosystem and has implemented several policies since 2011 to achieve its target. Consequently, the market share of EVs has surged, both globally and in India, over the past decade. Taking this into account, this study aims to identify the factors that influence EVs in a developing economy using the context of India.

This study identified important determinants of EV adoption from global literature and employed a multiple linear regression model (MLRM) using the ordinary least squares (OLS) technique. Secondary data were utilised to identify determinants in the Indian context, sourced from the Ministry, NITI Aayog, AQI, the Lok Sabha Question, and the Economic Survey of India.

This study found that the number of charging stations and local pollution levels significantly influence EV adoption in India. The insignificance of the other variables may be due to the emerging state of the Indian EV market.

This study adds to the growing body of literature on EV adoption in developing economies by analysing the factors that impact its adoption using regional data. In addition, this study provides a unique perspective on a developing economy and advocates a comprehensive policy for EV adoption that reflects long-term sustainability.
