Viešojo administravimo disciplinoje egzistuoja didelė teorinių viešojo valdymo modelių įvairovė, kuri, atrodo, nuolatos didėja. Tuo pačiu disciplinai trūksta meta‑teorijos kuri leistų nustatyti šių modelių santykį. Tai apsunkina sisteminių tyrimų viešajame administravime plėtrą. Disertacijoje atliekama dažniausiai sutinkamų literatūroje teorinių viešojo valdymo modelių tarpusavio santykių analizė ir remiantis šios analizės rezultatais tiriamas Lietuvos Respublikos Vyriausybės vaidmuo Lietuvos viešojo valdymo formavimesi ir raidoje. / The discipline of Public Administration is marked with an ever growing increase in theoretical models of governance. However, this theoretical proliferation is not matched by a meta‑theory that would allow building an understanding of the interrelation of these models. The dissertation provides an in‑depth analysis of selected theoretical models which is used as a basis of researching the role of the Government of Lithuania in the formation and development of Lithuanian public governance.

Boards of directors have been described as an integral part of corporate governance research, being at "the apex of the internal control system" (Jensen, 1993, p.862). Early corporate governance research has examined whether, and to what extent, board characteristics impact on performance. However, the results of studies that focused on board structure/composition and performance produced mixed outcomes. Consequently, we saw the emergence of research on board processes and their impact on board task performance. Research on board processes is still ongoing, and scholars have been interested in, among other processes, how knowledge and skills by board members are being used (Gabrielsson and Huse, 2004; Kor and Sundaramurthy, 2009). At the same time, there is a gap within educational research on how knowledge is being created within teams that are episodic in nature, such as boards (Forbes and Milliken, 1999). As such, the concept of learning has to date been under-researched in a board context. In this thesis, board processes are studied by exploring the processes involved in the acquisition and sharing of knowledge and skills in boards. Further, as a response to calls for the adoption of alternative research approaches to the study of boards (Pettigrew, 1992; Johnson et al., 1996), this research is conducted using a qualitative method based on a grounded theory approach. The study is conducted based on evidence from semi-structured interviews with UK board members. The findings show that the creation of knowledge in boards depends on two dialectical processes of learning (acquisition of knowledge and skills from the external environment and sharing of knowledge and skills in the internal environment). The qualitative findings show that 1) directors possess certain levels of knowledge related to specific boards task – which is also known as directors’ knowledge base; 2) the gap between the level of knowledge and skills needed to perform specific board tasks and the directors knowledge base is regarded as a gap in directors’ knowledge; 3) that there are two processes of filling the gap(s) in directors’ knowledge – the process of acquiring knowledge and skills (from the external environment), and the process of sharing knowledge and skills within the board; 4) that there are factors which are impacting on the processes of acquiring and sharing knowledge in boards; and 5) the processes of learning in boards are circular and board members must continually update their knowledge to enhance their capabilities. The thesis contributes to knowledge by revealing new insights into how board members acquire knowledge and skills (processes of learning) and factors that are impacting on learning in boards, underpinning former conceptual models. Qualitative analysis itemised different types of processes for both acquiring and sharing knowledge and skills in boards. Additionally, the qualitative analysis revealed various forms of learning styles that are being employed by board members either to acquire or share knowledge and skills. Finally, this thesis contributes to qualitative research in boards and its findings have implications for board practice, especially boards’ tasks performance and processes of learning.

Corporate governance can play a significant role in financial market stability and economic development. Corporate governance scholars have provided controversial results with respect to the relationships between corporate governance and both corporate financial performance and market value. Based on agency theory and institutional theory, the purpose of this correlational study was to investigate the relationship between corporate governance mechanisms, financial performance, and market value in Kingdom of Saudi Arabia's 116 firms from 2010 to 2014. Financial performance was measured by return on assets and return on equity, while market value was measured by Tobin's q. Corporate governance mechanisms involved in this study were board size, board independence, board committees, ownership structure, and executive compensation. The financial statements and corporate governance mechanisms collected from the websites of sampled firms and the Saudi stock market (Tadawul). The findings of multiple regression tests revealed a statistically significant relationship between corporate governance mechanisms and both corporate financial performance and market value. This study may contribute to social change by building confidence in the Saudi capital market and improving the lives of stakeholders and community in general. The results may help business leaders understand the influence of corporate governance on their firms' success and the country's growth. Academic researchers, investors, regulatory bodies, practitioners, and experts in the area of corporate governance may benefit as well.

This thesis uses a constructivist grounded theory approach to investigate nonprofit corporate governance in the UK; using data obtained from participatory observations of board and associated meetings, workshops, and unstructured elite interviews. Open codes are generated and brought together as concepts, which are then iteratively compared and grouped in open categories. These categories are then reassembled using the paradigm model into five axial codes: the clash of orthodoxies; clash of motivations; regulator versus board power; clash of rationalities; and effective board duality. A dialectical approach is then used to create the core category of the ‘clash of neoliberal and public service world views which exists at every level of the nonprofit sector’. This core category is analysed in terms of the subordinate contradictions: at an environmental level - regulatory power versus sector power; at board level - accountability; the SMT; board practices and rituals (professionalism, actual and symbolic authority, boards meetings as theatre, and ethical standards); the concept of challenge as an expression of power relations; and rationality and decision making; and at the individual level - motivations of directors, moral duty and social purpose, social group membership, identification, credibility and trust. The substantive theory is then situated within psychology, governance, and corporate governance theories. The contribution made by the thesis are identified as the: use of ethnography to describe the inner workings of the board; creation of a model of nonprofit corporate governance; identification of the importance of political, ideological, regulatory, and ethical contexts; and concept of power, and the senior management team as a component of the board. Further research is suggested into: (i) a comparison of corporate governance in the for-profit and nonprofit sectors; (ii) challenge within the nonprofit culture; and (iii) the SMT as a major player in governance.
