Since Montesquie's incisive differentiation of the principal forms of governance and their components, the rate at which theories of governance have been proposed has exponenetially grown now when we have a plethora of different theories on the best way to govern, lead and /or manage. Anyone interested in this topic is confronted with many conflicting schools of thought, from Weber's theory of the 'iron cage' to Wheatley's new-age concept of leadership. This seeming maze of different theories can be seen merely as different perspectives on the overall embracing concept of governance which is essentially the holistic conception and explanation of differentiated purposive human systems - about paradigms and systems that have their inception in and are limited by, human mind. The core challenge, then, is to put some order and rationale into the understanding of this 'many-headed ' concept of governance. This thesis meets this challenge by mapping out a cognitive framework that is capable of embracing and ordering all the multitudinous differentiated conceptions of human governance experienced at the different levels of society. In essence, this thesis reformulates the concept of organizational governance in terms of the metaphor of the human mind. The cognitive model of governance are embraced by the different organizations in different circumstances and why this is appropriate and necessary, how and why governance changes over time, and how it is important to institute processes of inquiry, dialogue and reflection in order to know and choose more consciously. As a consequence of using the mind metaphor to analyse governance in Western society, the key conclusion is that there has been a substantial shift or evolution in thinking from a mangerialist mindset to the more abstract politicist mindset. This fundamental shift in mindset is pervasive and influences the perspectives taken at many levels in the human governance systems. / Doctor of Philosophy (Management)

The aim of this dissertation is to examine the process of securitization of terrorism, to develop the role of the audience (public) at the individual level and subsequently to provide recommendations on an alternative way of fighting terrorism. In order to achieve this goal, the author uses socially constructivist securitization theory, critical terrorism studies and political psychology, namely cognitive and social psychology. Throughout the chapters, the securitization process of terrorism is explored; terrorism as a (to a certain extent) objective problem, further, from the point of view of critical terrorism studies, the security measures are assessed and public opinion is examined through public opinion polls. The author comes to the conclusion that public opinion is one of the key factors in implementing extensive security measures. Therefore, she further examines the factors that affect public opinion; the narrative, the role of the media, and ultimately the psychological processes influencing the perception of reality. It turns out that the narrative about terrorism and the media have their share in the public reaction to terrorism, but the role of the audience in the securitization process of terrorism is not fully explained and there are the psychological processes that illuminate it. Therefore, by running an experiment, the author examines the effect of three narratives about terrorism, based on psychological theories. It concludes that there is a potential for reducing the public's fears and thus the alternative fight against terrorism.

This paper intends to contribute to the subject focusing on the mechanical calculating machines designed in the first half of the nineteenth century by Charles Babbage (1791-1871). It presents the main motivations of its inventor, his ideas, difficulties and ingenuity to face some completely new and challenging technical problems. We also analyze the French motivations and solution to solve calculus problems. In the context of that time, we examined carefully the question of communication between man and machine, so far an intriguing innovation that generated enthusiasm, controversy and many speculations. We highlight Babbage s perception that there was "some slight analogy to the operation of the faculty of memory", an idea shared by some of his contemporaries. Even at that time, then, the idea of the "thinking machine" arose, ancestor of the more recent idea of the "electronic brain". Finally we refer to the not so expressive Babbage s technical legacy as opposed to a meaningful and engaging fact that he stimulated an opening for a new and fascinating human activity: the dialogue between man and the machine of his creation. Keywords / O tema das origens dos computadores tem despertado controvérsias que nem sempre ficam bem esclarecidas. Este trabalho pretende contribuir com esse assunto focalizando as máquinas calculadoras mecânicas projetadas na primeira metade do século XIX por Charles Babbage (1791-1871). São apresentadas as principais motivações de seu inventor, suas ideias, dificuldades e engenhosidade ao enfrentar alguns problemas técnicos completamente novos e desafiantes. Analisamos também as motivações e solução francesa para resolver os problemas de cálculo. No contexto dessa época, aprofundamo-nos na questão da comunicação do homem com a máquina, então uma intrigante novidade que gerou entusiasmos, controvérsias e muitas especulações. Destacamos a percepção de Babbage de que havia alguma leve analogia com as faculdades da memória , ideia compartilhada com alguns de seus contemporâneos. Surge então, já naquela época, a ideia da máquina de pensar , ancestral da idéia mais recente do cérebro eletrônico . Finalmente referimo-nos ao não tão expressivo legado técnico de Babbage em contraposição a um significativo e envolvente fato dele ter estimulado uma abertura para uma nova e fascinante atividade humana: o diálogo do homem com a máquina de sua criação
