Vicious Circles in Disease

Vicious and Virtuous Circles in the Management of Knowledge: The Case of Infosys Technologies

We adopt a systems perspective to explore the challenges that organizations face in harnessing knowledge. Such a perspective draws attention to mutually causal processes that have the potential to generate both vicious and virtuous circles. Based on a longitudinal study at Infosys TechnoV. Sambamurthy and Mani Subramani were the accepting senior editors for this paper. logies, we conclude that ...

Social Sciences Research on Infectious Diseases of Poverty: Too Little and Too Late?

Infectious diseases of poverty, also labeled tropical diseases or neglected tropical diseases (NTDs) and caused by pathogenic agents (viruses, bacteria, fungi, and other parasites), are viciously more prevalent among poor people. Though being preventable for the most part in a cost-effective way, they are devastating. These are, to name a few, Chagas disease, schistosomiasis, malaria, leprosy, ...

* Prepared for New Palgrave: A Dictionary of Economics

Economic activity in different industries is linked to each other through aggregate income (horizontal linkages) and input-output relationships (vertical linkages). Could such linkages give rise to vicious circles of underdevelopment or virtuous circles of development when there are increasing returns to scale at the firm level? We show that vicious or virtuous circles based on demand linkages ...

Revisiting the vicious circle of dry eye disease: a focus on the pathophysiology of meibomian gland dysfunction

Meibomian gland dysfunction (MGD) is the most frequent cause of dry eye disease (DED). Eyelid inflammation, microbial growth, associated skin disorders as well as potentially severe corneal complications culminate to make MGD a complex multifactorial disorder. It is probable that MGD is a heterogeneous condition arising from any combination of the following five separate pathophysiological mech...
