The Nexus Paradox: Legal Personality and the Theory of the Firm
(University of Hertfordshire, 2013-05-28)In the last four decades, one of the fastest-growing fields of research in economics has been the contractual theory of the firm developed in Coase’s (1937) footsteps. Yet despite what otherwise seems to be a genuine success ... -
Numerical Modelling of Mixing and Separating of Fluid Flows through Porous Media
(2018-02-01)In present finite element study, the dynamics of incompressible isothermal flows of Newtonian and two generalised non–Newtonian models through complex mixing–separating planar channel and circular pipe filled with and ... -
Nutrition and Metabolic Adaptation: the Assessment and Impact of Dietary Manipulation on Metabolic and Cellular Perturbation
(2017-07-20)It is well established that improved nutritional strategies can enhance both health and exercise performance. Scientific developments in recent years have furthered our understanding of cellular metabolism, which in turn, ... -
Occupational stress and work-life balance in UK academics
(University of Hertfordshire, 2006)The research presented in this thesis aimed to provide insight into the work-related wellbeing of a little-studied occupational group: academic employees working in universities in the UK. More specifically, it examined ... -
Off-Label and Unlicensed Medicines' Related Problems in Paediatric In-Patients
(2018-10-15)Background: Current legislations such as paediatric investigation plan (PIP) require pharmaceutical companies seeking marketing authorisation for a new medicine to provide evidence of studies in paediatrics to justify the ... -
On the Key Processes that Drive Galaxy Evolution: the Role of Galaxy Mergers, Accretion, Local Environment and Feedback in Shaping the Present-Day Universe
(2019-07-17)The study of galaxy evolution is a fundamental discipline in modern astrophysics, dealing with how and why galaxies of all types evolve over time. The diversity of present-day galaxies is a reflection of the processes ... -
An Online Survey to Investigate Clinicians’ Use of, Attitudes Towards, and Perceived Competency Around Outcome Monitoring Practices
(University of Hertfordshire, 2014-09-15)In recent years, there has been an ever increasing emphasis placed on the collection and use of patient reported outcome measures (PROM) in mental health services. This emphasis stems from a culture of evidence based ... -
