In the evolving global economy, boardroom governance has forged an increasing influence on what transpires in corporations today. Within the boardroom, expectations of board directors and executive management (key actors) have shifted dramatically due to the financial failures (i.e., Enron and WorldCom, etc.) and the ensuing global financial crisis in the 2000s. The belief is that these directors and managers contributed greatly to these crises (Boerner, 2011). Consequently, there is a growing appeal to study boardroom governance and the roles of board directors and executive managers, not from a structural description, but rather from a behavioral perspective. In the literature, corporate governance structural framework is well informed while the behavioral framework is lacking. Often referred to as a black box, board behavior is not well understood because board processes are not easily observed nor are researchers readily invited to do so (Barratt & Korac-Kakabadse, 2002). There is therefore a clear call for studies to examine the black box of boardroom governance (Erakovic & Overall, 2010; Lockhart, 2010; Huse et al, 2011). Recognizing this demand, an examination of the beliefs and values of the board directors and executive managers in their boardroom culture, was undertaken as the starting point to open the black box of boardroom governance.

This thesis has been written at Linköping University for the company Instrument Control Sweden AB (ICS). ICS is a small company located in Linköping that develops software and hardware for Unmanned Aerial Vehicles, UAV. At present, ICS has a fully functional autopilot called EasyPilot but they want to reduce the autopilot’s size to make it more attractive. The purpose of this thesis was to investigate if it was possible to reduce the size of the autopilot and how, in that case, it would be done. It was also necessary to examine whether the old processors should be replaced by new ones and how hard it would be to convert the old software to these new processors. To succeed with the goals many of the old components had to be changed for new, smaller ones. Some less necessary parts were also completely removed. The results showed that the size could be reduced quite a bit, exactly how much is hard to say since no PCB-layout were done. By doing some programming tests on the new components it could be shown that some parts of the old code could be reused on the new design. It was mainly algorithms and other calculations. However, a lot of new code still had to be written in order to successfully convert the old software to the new hardware.

Simulating the translatory motion of a vehicle during a gear shift gives a good basis to evaluate performance and comfort of a gear shift. This evaluation can be used for gear shifting strategy in an automatic transmission. A model of a diesel engine and it's electronic control system is developed to capture the engines behaviour in a vehicle simulation environment. The modelled quantities are brake torque, fuel consumption and exhaust gas temperature and are based on engine speed and pedal position. In order to describe these outputs the inlet air flow and boost pressure are also modelled and used as inner variables. The model is intended to be implemented on board a vehicle in a control unit which has limited computational performance. To keep the model as computationally efficient as possible the model basically consists of look-up tables and polynomials. First order systems are used to describe the dynamics of air flow and exhaust temperature. The outputs enables gear shift optimization over three variables, torque for vehicle acceleration, fuel consumption for efficiency and exhaust temperature to maintain high efficiency in the exhaust after treatment system. The engine model captures the low frequent dynamics of the modelled quantities in the closed loop of the engine and it's electronic control system. The model only consists of three states, one for the pressure build up in the intake manifold and two states for modelling the exhaust temperature. The model is compared to measured data from a engine test cell and the mean absolute relative error are lower than 6.8%, 7.8% and 5.8% for brake torque, fuel consumption and exhaust gas temperature respectively. These results are considered good given the simplicity of the model.

Board involvement in Information Technology (IT) governance and the antecedents and consequences of such involvement are examined from both a theoretical and practical perspective. Practitioner and academic IT governance literature highlight the need for increased board involvement in IT governance; however, it seems that many corporate boards do not practice a formalized style of IT governance, while those that do, face significant challenges. A gap clearly is seen as in spite of the potential benefits of board IT governance and the costs of ineffective oversight, there has been little field-based research in this area, nor adequate application of theory. This research addresses this gap by developing and testing an exploratory multi-theoretic framework of board IT governance. Drawing upon strategic choice and institutional theories, and Ashby’s Law of Requisite Variety, a model of the antecedents (organization factors and board attributes) of board IT governance and its consequences (financial performance and operational performance) is both developed and tested. Unlike previous studies, board IT governance is designated as a central construct in this model rather than a secondary factor. Constructs of board IT governance and IT competency are explored and multi-item measures for both constructs are developed. Board IT governance is conceptualized as the extent of offensive and defensive board oversight activities, while IT competency is conceptualized as the extent of IT expertise (IT knowledge, experience and training) and IT governance mechanisms (structures, processes and relational mechanisms). Detailed interviews with board members enabled a preliminary examination of the theoretical framework. To further test the propositions in the theoretical framework and to validate the measures for the board IT governance and IT competency constructs, an online survey was administered to corporate directors across Canada. Exploratory Factor Analysis and Ordinary Least Squares multiple regression were used to analyze responses from 188 directors. The board IT governance and IT competency constructs were well supported by the data. In addition, the results show that the organizational factors explain 28% of the variance in board IT governance, and that board attributes explain 39% more of the variance, for a total explained variance in board IT governance of approximately 68%. The results also show that board IT governance has a positive impact on operational performance, explaining 19% of the variance in operational performance. However, the proposed impact of board IT governance on financial performance, and the impacts of ‘fit’ between role of IT and board IT governance approach on financial and operational performance were not supported by the survey results. Overall, this research makes a theoretical contribution by: focusing on the board’s role in IT governance; developing a multi-theoretical model of the antecedents and consequences of board IT governance; developing measures of board IT governance and board IT competency, and; empirically assessing the antecedents and consequences of board IT governance.

This study examines the significance of corporate governance mechanisms during the corporate governance reform using a sample of 117 non-financial Japanese firms listed on the Tokyo Stock Exchange over the period 1989 to 2001. Japans prolonged recession brought about numerous reforms in post-bubble Japan. Although it is plausible to infer that the corporate governance system in Japan may have been a factor that led to the sustained recession in Japan, it is vague as to how deep and thorough the changes to Japanese corporate governance have been. The inference is that adverse impact of corporate governance may have been one of the factors that led to the sustained recession in Japan. Numerous proposals have been offered and some implemented in an attempt to fix problems exposed during the recession period in the 1990s. Remedies include instituting reforms to corporate governance by establishing new standards, punishing malpractice, and changing corporate board structures. Many Japanese firms look abroad for alternate governance mechanisms to integrate into their own system of control. As such, most reforms propose changes, for the most part, reflecting the American-style of corporate governance: alignment in incentives between top management and shareholders, board size reductions, and greater board independence to promote better monitoring and firmer discipline. <p>The significance of proposed changes to traditional Japanese corporate governance is examined in this study. Using a different econometric approach from that of previous studies, the relationship between board composition and firm performance is examined with a simultaneous framework of equations. The purpose of this empirical framework is to tackle potential endogeneity problems between board composition, governance and performance variables. Results show that: (1) there exists a significantly negative relationship between turnover of members of the board of directors and firm performance; (2) board size reduction is significant, but there is no evidence of consistent relationship between outside directorship and firm performance. (3) While keiretsu membership is generally relevant in linking board turnover and performance in Japan, board turnover is sensitive to performance in firms where ownership is concentrated than where ownership is dispersed. (4) President turnover, whether routine or non-routine, is unrelated to performance. Overall, results support that the entire board assumes responsibility for the firms performance and the 2SLS model is an effective estimator for estimating the relationship between board composition and firm performance.

Investment, financing and dividend policies are critical for firms. The natures of these three policies may be significantly influenced by bankers on the board. Previous studies have examined the relationship between financing policy and bankers on the board. However, the influence of bankers on the board on corporate investment and dividend policies remains unexamined. Therefore, this paper tries to shed further light on whether bankers on the board affect corporate investment-cash flow sensitivity and dividend policy. This study collects data from Taiwan publicly traded corporations that have banker directors between 2003 and 2007, together with a matching sample consisting of firms without banker directors. Variables used to construct empirical analyses are from the Taiwan Economic Journal (TEJ) database. The results show that the presence of bankers appointed to corporate directors and the percentage of banker directors positively affect the firm¡¦s investment-cash flow sensitivity positively. This study also finds a negative relationship between the presence of banker directors and the likelihood of dividend payment. The percentage of banker directors has negative impacts on the likelihood of dividend payment and corporate dividend payout ratio.

This study investigates the effect of board networks on M&A transactions. I select 331 samples of M&A transactions among U.S. Fortunate 500 companies which are also U.S. public companies from 2002 to 2011. In addition, I use definition of board networks by Cai & Sevilir (2012) to identify whether there exist board networks in each sample. About research design, first I use event study methodology to estimates cumulative abnormal returns (CAR), and then examine the relationship between the board networks and M&A performance through regression analysis. Empirical analysis results are as follows:¡G 1. M&A announcement brings significantly negative abnormal returns to the U.S. Fortunate 500 companies. 2. The board networks will decrease the M&A performance for the U.S. Fortunate 500 companies. 3. The board networks are not efficient information channels for the U.S. Fortunate 500 companies.

The primary purpose of the study was tri-fold. The study was conducted to (1) determine differences between faculty users and faculty non-users awareness, perceptions and attitudes about the role and processes of the IRB on one 1890 land grant campus; (2) determine when controlling for status, rank, years of service, and age and the degree to which these variables contributed to the identification of the faculty profile for faculty users and faculty non-users of the local IRB at one 1890 land grant university; and (3) expand scholarly works and empirical literature related to the local IRB's role in human participant's research and its impact upon the university land grant community. This study was conducted at one 1890 land grant institution located in south central United States during the fall of 2007. The sample group consisted of 50 faculty who were self-identified as faculty users and faculty non-users of the IRB and reported their status, rank, years of service, and age. An electronic survey instrument was used to obtain data for this study. Secondary data was secured and analyses were conducted to assess the levels of awareness, perceptions, and attitudes about the role and processes of the Institutional Review Board (IRB), using the SPSS analysis package. Several procedures were employed to aggregate the data: frequencies and cross tabulations, analysis of variances of covariates (ANCOVA), and multivariate analyses of covariates (MANCOVA) to compare specific group mean scores of faculty users and faculty non-users, tenure and tenure track. The significance level was set using an alpha level of .05. The findings revealed (1) that faculty users and faculty non-users had differences between the levels of awareness and attitude; (2) perception remained high among faculty users and faculty non-users; however, (3) when controlling for years of service and age, there were significant differences between the faculty user and faculty nonuser groups.

Current research in corporate governance focuses primarily upon minimization of agency costs in the shareholder-management relationship. In this dissertation, I examine a complimentary perspective based upon stewardship theory. The model developed herein leverages past research on socioemotional wealth to identify CEO attributes associated with stewardship behavior. I examine whether these attributes lead to positive firm performance. Moreover, I examine how family ownership and board of director characteristics influences the CEO stewardship – firm performance relationship. A 3-year unbalanced panel dataset using 268 S&P 1500 firms is analyzed using generalized least squares regression. All covariates lag the dependent variable by 1-year; constructs are included to control for popular agency prescriptions used to monitor, control, and incentivize executives. I find no relationship between the hypothesized constructs related to CEO stewardship (board memberships, organizational identity, and board tenure) and firm performance (Tobin’s Q). However, results reveal family ownership positively moderates the relationship between the quantity of CEO board memberships and firm performance. Additionally, the presence of affiliated directors and community influential directors positively moderates the CEO board memberships-firm performance relationship. The presence of community influential directors also positively moderates the relationship between CEO organizational identity and firm performance. Results from this dissertation provide moderate support for stewardship theory as a compliment to agency theory in corporate governance literature. There is evidence that family ownership and board of director attributes strengthen the relationship between those CEO stewardship constructs and firm performance. However, lack of a direct relationship between the CEO stewardship constructs and firm performance suggest a need more fine-grained constructs that measure stewardship. A substantial amount of research exists in corporate governance using the principal-agent model. The research herein extends this research by using stewardship theory to compliment the dominant agency model. I hope this research encourages scholars to take an integrative approach by (1) taking a renewed look at alternate theories of corporate governance such as stewardship theory, and (2) continue work that focuses upon firm performance maximization through CEO stewardship as well as agency loss mitigation through monitoring and control of the CEO.
