Online games increasingly sell virtual goods to generate real income. As a result, it is increasingly important to identify factors and theory of consumption values that affect intent to purchase virtual goods in online games. However, very little research has been devoted to the topic. This study is an empirical investigation of the factors and theory of consumption values that affect intent t...

Ion channels contribute to virtually all basic cellular processes, including such crucial ones for maintaining tissue homeostasis as proliferation, differentiation, and apoptosis. The involvement of ion channels in regulation of programmed cell death, or apoptosis, has been known for at least three decades based on observation that classical blockers of ion channels can influence cell death rat...

The effects of bepridil, a potent antiarrhythmic drug, on the activity of ATP-sensitive K(+) (K(ATP)) channels and Na(+)-activated K(+) (K(Na)) channels were examined in isolated patches from guinea pig ventricular myocytes. In inside-out membrane patches, K(ATP) channel currents were recorded with 140 mM [K(+)](i) and 140 mM [K(+)](o) solutions, and K(Na) channel currents were recorded by incr...

Sulfonylurea derivatives glibenclamide and tolbutamide are selective blockers of ATP-sensitive K+ (KATP) channels. However, their ability to prevent cellular K+ loss and shortening of action potential duration during ischemia or hypoxia in the intact heart is modest compared with their efficacy at blocking KATP channels in excised membrane patches. In the isolated arterially perfused rabbit int...

This paper sets up a model to account for differences in total factor productivity due to differences in enforcement of contracts. Vertical specialization generates the need for intra-period credit, because final goods producers cannot pay their intermediate goods suppliers before they produce their final good. The paper shows that if there are enforcement problems, the capital distribution is ...

Why do some urban governing regimes realize a more equal distribution of public goods than others? Local government interventions in São Paulo, Brazil, have produced surprisingly effective redistribution residential — housing and sanitation between 1989 2016. I use original interviews archival research for comparative-historical analysis variation across time Paulo’s governance sanitation. argu...

1. Mechanoelectric feedback (MEF) in the heart is the process by which mechanical forces on the myocardium can change its electrical properties. Mechanoelectric feedback has been demonstrated in many animal models, ranging from isolated cells, through isolated hearts to whole animals. In humans, MEF has been demonstrated directly in both the atria and the ventricles. It seems likely that MEF pr...

This paper evaluates the joint impact of exclusive channels and revenue sharing on suppliers and retailers in a hybrid duopoly common retailer and exclusive channel model. The model bridges the gap in the literature on hybrid multichannel supply chains with bilateral complementary products and services with/without revenue sharing. The analysis indicates that, without revenue sharing, the suppl...

The story of the growth of emerging economies is about the growth of their marketing institutions. Marketing channels are the key marketing institution in enabling the flow of goods and services. However, marketing scholars typically rely on models and theories devised in the developed economies to study the marketing channels in emerging economies, and these include theories based on political...
