<p>This thesis seeks to explore the role of agent or 'user' intention in the fields of Management Science and Systems Thinking. Primarily through the use of various modelling approaches these fields seek to provide assistance to organisational stakeholders who are looking to intervene in situations with a view to dealing with problems and/or bringing about some form of 'improvement'. Although the literature acknowledges that the various methodologies, techniques and tools of MS/ST can be used flexibly depending upon user intention, to date, intention itself has not been the subject of detailed investigation. The thesis seeks to plug this gap in the literature. In exploring intention in some detail the thesis interlinks philosophy, theory and empirical work. The philosophical and theoretical components allow us to conceptualise intention and better understand how it might work in concrete settings. The empirical component, conducted with a team of action researchers, grounds the discussion in practice. The main proposition of the thesis is that intention is a dual-sided phenomenon, i.e. "we do things intentionally, and we intend to do things" (Bratman, 1997). Thus intention has a present and a future side. The research reported on through the thesis shows how, through language and actions, both sides of intention can significantly shape the nature of interventions. This being the case, the value of the work is that it provides new ways of accounting for and learning from interventions; in particular, it provides new frameworks for practitioners to better reflect on and guide their actions.</p>

Tendon exhibits anisotropic, inhomogeneous and viscoelastic mechanical properties that are determined by its complicated hierarchical structure and varying amounts/organization of different tissue constituents. Although extensive research has been conducted to use modelling approaches to interpret tendon structure–function relationships in combination with experimental data, many issues remain unclear (i.e. the role of minor components such as decorin, aggrecan and elastin), and the integration of mechanical analysis across different length scales has not been well applied to explore stress or strain transfer from macro- to microscale. This review outlines mathematical and computational models that have been used to understand tendon mechanics at different scales of the hierarchical organization. Model representations at the molecular, fibril and tissue levels are discussed, including formulations that follow phenomenological and microstructural approaches (which include evaluations of crimp, helical structure and the interaction between collagen fibrils and proteoglycans). Multiscale modelling approaches incorporating tendon features are suggested to be an advantageous methodology to understand further the physiological mechanical response of tendon and corresponding adaptation of properties owing to unique in vivo loading environments.
