    Abstract Contemporary society is obsessed with knowledge, leaving its less seductive counterpart, ignorance, in the shadows. However, as an expanding literature suggests, it is equally important to understand ignorance and consider its varieties. This study specifies the nature of wilful ignorance in organizations. It does so by (a) making a distinction between the will of an actor and the epistemic properties of ignorance, and showing how these two form a dynamic relationship, (b) linking wilful ignorance to its various drivers and (c) suggesting how our concept of wilful ignorance can be used in the study of organizations. Rather than reducing the phenomenon into a simple to know/to ignore dichotomy, we concentrate on its processual and dynamic nature. Moreover, we explore the complexities and ambiguity inherently involved in all knowing and ignoring as well as the role of agency in reducing the harmful effects of wilful ignorance in organizations.

    Abstract We have previously shown that an excess of deoxycorticosterone acetate and high sodium chloride intake (DOCA/salt) in one-renin gene mice induces a high urinary Na/K ratio, hypokalemia, and cardiac and renal hypertrophy in the absence of hypertension. Dietary potassium supplementation prevents DOCA/salt-induced pathological processes. In the present study, we further study whether DOCA/salt-treated mice progressively develop chronic inflammation and fibrosis in the kidney and whether dietary potassium supplementation can reduce the DOCA/salt-induced renal pathological process. Results showed that (1) long-term DOCA/salt-treated one-renin gene mice developed severe kidney injuries including tubular/vascular hypertrophy, mesangial/interstitial/perivascular fibrosis, inflammation (lymphocyte's immigration), proteinuria, and high serum creatinine in the absence of hypertension; (2) there were over-expressed mRNAs of plasminogen activator inhibitor-1 (PAI-1), fibronectin, collagen type I and III, interferon-inducible protein-10 (IP-10), monocyte chemotactic protein-1 (MCP1), transforming growth factor-
