Abstract Superconducting gate-model quantum computer architectures provide an implementable model for practical quantum computations in the NISQ (noisy intermediate scale quantum) technology era. Due to hardware restrictions and decoherence, generating the physical layout of the quantum circuits of a gate-model quantum computer is a challenge. Here, we define a method for layout generation with a decoherence dynamics estimation in superconducting gate-model quantum computers. We propose an algorithm for the optimal placement of the quantum computational blocks of gate-model quantum circuits. We study the effects of capacitance interference on the distribution of the Gaussian noise in the Josephson energy.

In this study we draw on a series of in-depth interviews with chief executives of some of South Africa’s most prominent businesses, to investigate how their careers unfolded as they rose to the top of their organisations.Twenty-seven CEOs of South Africa’s top companies were interviewed. Eleven of these companies are listed among the top 50 South African companies.We trace the evolution of leadership, from its embryonic beginnings in childhood and adolescence, through the different stages of a developing career to the crucial transformation of an operational mindset into a strategic one.We examine the circumstances that led to these CEOs being appointed and describe the difficulties of transitioning from a senior management role into that of chief executive. We look at the competencies and experience necessary to be effective as the leader of an organisation, as well as the role played by motivation and self-belief. Finally, we identify the unique leadership challenges faced by chief executives in South Africa and pass on their advice to the country’s next generation of leaders.

Our study covered the development and evolution of the management accounting system of a subsidiary company in a group. Our study was a longitudinal one starting from the incorporation of the company. We divided this period into five stages according to the major events happened, namely the formation of the company, the invoicing crisis, the conflict with parent company, the conflict with fellow subsidiaries, and the influence of the chief executive. In our analysis we applied the three dimensions of structure in the theory of structuration (i.e., signification, legitimation and domination). The structuration theory explained the emergence of certain phenomena and events that were not explained by traditional accounting theories. Many events in our study validated the core ideas of the structuration theory which composes of the concepts of structure, system and duality of structure. The phenomena suggested that structure was both the medium and outcome of the conduct it recursively organized. Other features of the theory, such as the dialectic of control and system contradiction, were also applicable

Since 2003 the number of small- and medium-sized enterprises (SMEs) has increased exponentially in Iraqi Kurdistan. To facilitate further growth the owners and chief executive officers of these enterprises have sought to improve their leadership skills. This study examined the effect of transactional and transformational leadership styles on organizational commitment and performance in Iraqi Kurdistan SMEs, and the mediating effect of organizational commitment in these relationships. We distributed 530 questionnaires and collected 400 valid responses (75% response rate) from 115 SME owners/chief executive officers and 285 employees. The results demonstrate there were positive effects of both types of leadership style on organizational performance. Further, the significant mediating effect of organizational commitment in both relationships shows the importance of this variable for leader effectiveness among entrepreneurs in Iraqi Kurdistan, and foreign entrepreneurs engaging in new businesses in the region.

SYNOPSIS Accounting scholars theorize that audit price is a function of a client's audit and business risk. Existing research finds that the functional expertise of Chief Executive Officers (CEOs) in finance improves financial reporting quality (Matsunaga, Wang, and Yeung 2013), increases profitability, and reduces the likelihood of firm failure (Custodio and Metzger 2014). These factors suggest that auditors' engagement risk decreases when incumbent CEOs possess financial expertise, raising the likelihood that auditors will charge these firms lower fees. In this study, we examine whether CEOs' work experience in accounting- and finance-related jobs affects audit fees. Using a panel of U.S. firms between 2004 and 2013, we find that firms that have a financial expert CEO pay lower audit fees. Our results are robust to various specifications, including firm-fixed effect model and specifications that control for other CEO- and Chief Financial Officer (CFO)-specific and audit committee characteristics. Our findings thus add to the literature on the advantages and disadvantages of a functional background of top managers and how this background can create value for a firm through savings in audit fees.
