How do our everyday actions shape and transform the world economy? This volume of original essays argues that current scholarship in international political economy (IPE) is too highly focused on powerful states and large international institutions. The contributors examine specific forms of â everyday' actions to demonstrate how small-scale actors and their decisions can shape the global economy. They analyse a range of seemingly ordinary or subordinate actors, including peasants, working classes and trade unions, lower-middle and middle classes, female migrant labourers and Eastern diasporas, and examine how they have agency in transforming their political and economic environments. This book offers a novel way of thinking about everyday forms of change across a range of topical issues including globalisation, international finance, trade, taxation, consumerism, labour rights and regimes. It will appeal to students and scholars of politics, international relations, political economy and sociology.

This paper proposes that atherosclerosis is initiated by a signaling event that deposits calcium hydroxyapatite (Ca-HAP). This event is preceded by a loss of mechanical structure in the arterial wall. After Ca-HAP has been deposited, it is unlikely that it will be reabsorbed because the solubility product constant (K sp) is very small, and the large stores of Ca +2 and PO 4-3 in the bones oppose any attempts to dissolve Ca-HAP by decreasing the common ions. The hydroxide ion (OH -) of Ca-HAP can be displaced in nature by fluoride (F -) and carbonate (CO 3-2) ions, and it is proposed that anions associated with cholesterol ester hydrolysis and, in very small quantities, the enolate of 7-ketocholesterol could also displace the OH -of Ca-HAP, forming an ionic bond. The free energy of hydration of Ca-HAP at 310 K is most likely negative, and the ionic radii of the anions associated with the hydrolysis of cholesterol ester are compatible with the substitution. Furthermore, examination of the pathology of atherosclerotic lesions by Raman and NMR spectroscopy and confocal microscopy supports deposition of Ca-HAP associated with cholesterol. Investigating the affinity of intermediates of cholesterol hydrolysis for Ca-HAP compared to lipoproteins such as HDL, LDL, and VLDL using isothermic titration calorimetry could add proof of this concept and may lead to the development of a new class of medications targeted at the deposition of cholesterol within Ca-HAP. Treatment of acute ischemic events as a consequence of atherosclerosis with denitrogenation and oxygenation is discussed. © the author(s), publisher and licensee Libertas Academica Ltd.
