Background: Health research training is an important part of medical education. This study was conducted to assess the level of knowledge and attitudes regarding health research in a group of Pakistani medical students at Aga Khan University, Karachi.

Since cardiac ultrasound was introduced into medical practice around the middle twentieth century, transthoracic echocardiography has developed to become a highly sophisticated and widely performed cardiac imaging modality in the diagnosis of heart disease1. This evolution from an emerging technique with limited application, into a complex modality capable of detailed cardiac assessment has been driven by technological innovations that have both refined ‘standard’ two dimensional and Doppler imaging and led to the development of new diagnostic techniques. Accordingly, the adult transthoracic echocardiogram has evolved to become a comprehensive assessment of complex cardiac anatomy, function and haemodynamics. This guideline protocol from the British Society of Echocardiography aims to outline the minimum dataset required to confirm normal cardiac structure and function when performing a comprehensive standard adult echocardiogram and is structured according to the recommended sequence of acquisition. It is recommended that this structured approach to image acquisition and measurement protocol forms the basis of every standard adult transthoracic echocardiogram. However, when pathology is detected and further analysis becomes necessary, views and measurements in addition to the minimum dataset are required and should be taken with reference to the appropriate British Society of Echocardiography imaging protocol. It is anticipated that the recommendations made within this guideline will help standardise the local, regional and national practice of echocardiography, in addition to minimising the inter and intra-observer variation associated with echocardiographic measurement and interpretation.

Purpose The purpose of this paper is to extend the understanding and application of interactive ties creating value through board characteristics, ownership concentration and firms’ performance by using a contingent theoretical-based framework based on the amalgamation of resource dependence theory, stakeholder theory, agency theory, stewardship theory and institutional theory in a country with weak political environment. Design/methodology/approach This study includes a sample of an unbalanced panel of 309 non-financial sector firms listed on Pakistan Stock Exchange (PSX) from 2005 to 2016. In order to address the issue of unobserved heterogeneity, simultaneous and dynamic endogeneity, the current study employed the technique Arellano–Bond dynamic panel data estimation under assumptions of GMM (Arellano–Bond, 1991). Findings The empirical results suggest that the presence of concentrated ownership moderates and helps to overcome the agency problems through different governance mechanisms (such as board size, independent directors and CEO duality). The larger boards are found to be beneficial whereas the higher representation of independent directors in the board is found to be detrimental for Pakistani firms. Research limitations/implications Limitations of the study are, first the current study has analyzed public-listed firms from the non-financial sector, and second the study has only focused on the financial aspect of the performance. The future research could include other proxies of corporate governance and ownership structure such as board diversity and meetings, audit committee and managerial ownership, etc. Practical implications The research also helps Pakistani policy makers in numerous ways. First, the current study confirms the monitoring and expropriation effect of ownership concentration in corporate governance and performance mechanism. Thus, the Security and Exchange Commission of Pakistan (SECP) should make such policies which protect the corporate board against the influence of concentrated ownership so that the interests of the minority shareholders are protected. Second, SECP should ensure that all the listed firms declare a comprehensive profile of their directors (such as academic qualification, age and experience) in their annual reports for the better understanding of the governance−performance mechanism. Originality/value The current study augments the emerging body of literature on corporate governance and firm performance mechanism through the amalgamation and testing of existing theories in an emerging economy like Pakistan by using wider and newer data set.

Purpose The purpose of this paper is to investigate the barriers inhibiting the adoption of green building and measures to promote this approach in Pakistan. Design/methodology/approach Barriers and measures were identified and examined by using a combination of research methods, including literature review, questionnaire survey, and in-depth interviews with the construction industry-related practitioners working in Pakistan. Ranking technique and factor analysis were used to identify the significant issues associated with the adoption of green building practices. Findings As per the survey results, the most critical barrier is “lack of awareness among people about the importance and advantages of adopting green building practices,” followed by “lack of incentives from government” and “lack of green building codes and regulations,” respectively. The results also indicate that most important measure to promote the adoption of green buildings is “creation of public awareness toward green initiatives through seminars, workshops, and discussions,” followed by “availability of green building codes and regulations (mandatory to apply)” and “financial incentives and penalties by the government (e.g. soft loan, tax) for promoting green building practices,” respectively. Research limitations/implications Research limitation is that its findings, other than Pakistan, cannot be generalized to other developing countries. Practical implications Findings of the research will be helpful in sensitizing the regulatory agencies, the policy makers, and the building construction practitioners about the barriers to adoption of green building practices. The suggested measures will help in devising policies and economic measures to promote the construction of green and environment-friendly buildings. Social implications This research will help the common people to know about the importance of green buildings that may lead to a deviation from the practice of traditional buildings to a widespread trend of building green buildings. This will lead to drastic reduction in demand for energy and considerable monetary savings for the common people. Originality/value The findings of this study are expected to contribute valuable information to decision makers for the better understanding of key issues that call for more attention in the promotion of efforts of green building practices in Pakistan. The results are based on the perception of local stakeholders, but might also be helpful for policy makers in other countries.
