The paper discusses community enforcement in infinitely repeated, two-action games with local interaction and uncertain monitoring. Each player interacts with and observes only a fixed set of opponents, of whom he is privately informed. The main result shows that when beliefs about the monitoring structure have full support, efficiency can be sustained with sequential equilibria that are indepe...

With the evolution of electricity market transformation, there is a renewed interest in distributed generation (DG)—that has a promising role for mitigating technical, regulatory, and environmental constraints in the electricity sector. These benefi ts are further enhanced with the ability of such DG in heat recovery applications in which the waste heat is used to produce hot water, heat buildi...

Abstract : This paper proposed a new high-voltage gain resonant switched-capacitor dc-dc converter for high-power offshore wind energy systems. The proposed new dc-dc converter is characterized by the resonant switching transitions to achieve minimal switching losses and maximum system effi ciency. Here, the converter operates at fi fteen times as high as the input voltage with a small device c...

Advances in neuroscience and neurotechnology have necessitated discussions on the ways that such developments could be used as weapons in contexts of national security, intelligence, and defense. This paper defi nes the concept of neuroweapons, and elucidates operational issues associated with their use to aid informational and strategic intelligence, such as brain-machine interfaces to improve...

Real-business-cycle models rely on total factor productivity (TFP) shocks to explain the observed co-movement between consumption, investment and hours. However an emerging body of evidence identifies “investment shocks”as important drivers of business cycles. This paper shows that a neoclassical model consistent with observed heterogeneity in labor supply and consumption across employed and no...

recent Korean governments have attempted to use social partnership as a mechanism to achieve cooperative and peaceful industrial relations and to balance economic effi ciency with social equity in the context of globalisation. This paper has two aims. First it seeks to put the current social partnership experiment in historical perspective and argues that current developments in Korean industri...

Two experimental factors (dietary treatment with or without pelleted-concentrate supplement (PCS) and sex) were investigated in crossbreed post-weaning calves to monitor their effects on performance, hematological profile, and plasma mineral concentration. Twenty-four post-weaning calves were classified according to sexually (either male or female) and randomly distributed into two dietary trea...

Thiamine diphosphate functions as a cofactor in enzymes that catalyze essential reactions in metabolic pathways of all organisms. Phosphoketolase is a thiamine diphosphate-dependent key enzyme in the catabolism of sugar in various microbes. In particular, this enzyme is indispensable for unusually high effi ciency of energy production of the glycolytic pathway of benefi cial commensal bacteria,...
