Comparative computational study of thrombosis in cerebral and abdominal aortic Aneurysms

Thrombosis is closely linked to aneurysm evolution. In some cases, the presence of a clot can accelerate the time to aneurysm rupture while in others, it can stabilise the aneurysm and prevent rupture. The few computational models that simulate aneurysm thrombosis have focused on either cerebral aneurysms or on abdominal aortic aneurysms. The aim of … [Read more]

Disability and reproduction in Africa: A multi-methods invest igation to identify, describe and determine the sexual, reproductive and maternal healthcare needs and challenges of women with disability in Ghana

Persons with disabilities (PWDs) constitute 15% of the world’s population. PWDs are however one of the most marginalised groups, especially in many low-income settings of Africa. This disadvantage transcends several spheres: PWDs have generally poorer health, lower education, fewer economic opportunities and higher rates of poverty. Women with disability are particularly more likely to be … [Read more]

Jurisdictional Rivalries between Company and State

This contribution to the research theme Crossing Borders, centres on two questions posed explicitly by the subtheme, Boundaries and Legal Authority in a Global Context. The first is how to understand in normative and conceptual terms, the changing capacity of the state to regulate (in the face of) cross-border activity, and the second is the … [Read more]

“Dementia: a growing problem in South Africa and the world”

Prosperous people live longer and old age carries a high risk of dementia, a condition that is so far neither preventable nor curable. The trend of incidence of Alzheimer’s Disease (AD), the most common form of dementia, is increasing all over the world. When AD is consolidated with other dementias with similar clinical profiles, it … [Read more]

We Don’t Need Another Hero

In a 2008, post-Polokwane missive to ANC president, Jacob Zuma, declaring his refusal to campaign for the African National Congress (ANC) in the upcoming 2009 general election, recently-deposed South African President Thabo Mbeki famously declared: “… I find it strange in the extreme that today cadres of our movement attach the label of a “cult … [Read more]

Global Citizenship and the Practice of Being Human. South African Visions and the legacy of Enlightenment

This project addresses the idea of global citizenship and common humanity in South Africa today. These ideas were powerful in Enlightenment Europe, where they promised a new regime of justice in opposition to despotism, exploitation, and slavery. But they were also highly problematic, since they tended to obscure cultural difference and impose European values on … [Read more]

Scaling the drivers and consequences of biodiversity change

Biological diversity is intrinsically scale-dependent, and understanding its scaling properties may help us better manage and conserve it. Factors such as invasive alien species, climate change or habitat fragmentation can have strikingly different effects on local diversity and on coarser-scale (regional or global) diversity, and indeed it may be possible to deduce the drivers of … [Read more]

Climate Change and the Emerging Disease Crisis: An Existential Threat to Technological Humanity

The emerging infectious disease (EID) crisis encompasses all pathogens affecting humans and the species upon which we depend for survival and socio-economic development. It constitutes an existential threat of global proportions. Humanity is playing a losing game with respect to emerging diseases. The Stockholm Paradigm is a new conceptual framework that explains the surprising ease … [Read more]

The Functional Structure of Brain Asymmetries: A Unified Theory

Hemispheric asymmetries play an important role in almost all cognitive functions. Despite this tremendous relevance, our understanding of the neurobiological fundaments of lateralization is just in its infancy. In the last decade I tried to streamline my research on bird and human asymmetries such that overlapping phenomena were studied with diverse neuroscientific methods in both … [Read more]

Controlling Landscapes and Bodies

During my time at STIAS I will collaborate with Stellenbosch and Cape Town faculty in both the humanities and the sciences to look at the positioning and chronology of Egyptian rock art in the Eastern Sahara in order to establish whether the animal or human images shown reflect changes in the environment and how it … [Read more]
