This paper studies whether banks charge higher or lower interest rates on loans to firms with overconfident CEOs. It establishes a theoretical model to show the relationship between the loan rate and overconfidence of the borrowing firm’s CEO. It also conducts empirical analyses to test the predictions of the model. As predicted in the model, firms with overconfident CEOs enjoy lower loan rates...

Waste heat is a free and abundant energy source, with 15% of global total use existing as waste above 600 K. For 600–900 K temperature range, near-field thermophotovoltaics (NFTPVs) are theorized to be the most effective technology recycle into electrical power. However, date, experimental efficiencies have not exceeded 1.5%. In this work, we optimize efficiency three modeled InAs/InAsSbP-based...

Within the framework of circular economy, waste litchi's skins were upgraded and transformed into electrocatalysts for oxygen reduction reaction (ORR) hydrogen evolution (HER). The pyrolyzed, activated, then used as carbon support fabricating metal–nitrogen–carbons (M–N–Cs) which belong to a promising class platinum group metal-free electrocatalysts. activated char was functionalized with trans...

We present an approach to accelerate spherical range-search (SRS) for dynamic points that employs the computational power of many-core GPUs. Unlike finding k approximate nearest neighbours (ANNs), exact SRS is needed in geometry processing and physical simulation to avoid missing small features. The spatial coherence of query points and the temporal coherence of dynamic points are exploited in ...

Both authors contributed equally to the paper. The helpful comments of Ron Burt, Jerry Davis, Ranjay Gulati, Paul Hirsch, Mark Shanley, and Brian Uzzi are appreciated. This study seeks to reconcile traditional sociological views of the corporate board as an instrument of elite cohesion with recent evidence of greater board activism and control over top management. We propose that CEO-directors ...

This study introduces two dimensions of strategic leadership, termed evolutionary and revolutionary specifically developed for top executives of high technology firms. Evolutionary leadership reflects a CEO’s ability to respond to changing competitive conditions and explore new paths of growth as well as exploit existing ones by redefining and extending the boundaries of the firm to new product...

Heinrich Steininger CEO logi.cals Austria [email protected] www.logicals.com The growing demand for flexibility and adaptability in automation systems requires appropriate concepts and methods already in the development stage. By using feature models, the variability of system components can be explicitly modeled. Variants can be derived by simple configuration and automatic gene...

Inflammatory bowel disease (IBD) is a chronic condition of the intestine with unknown etiology involving multiple immune, genetic and environmental factors. We were interested to examine the effect of total extract from Zataria multiflora Boiss, a folk medicinal plant on prevention and treatment of experimental IBD. Z. multiflora was administered (400, 600, 900 p.p.m.) through drinking water to...

Since nonuniform drying in the continuous microwave harms safety and quality of dried food materials, a significant improvement can be achieved by controlling application time microwave. This study aimed to investigate influence power at constant pulse ratio during zucchini on different product characteristics. The samples were first exposed microwaves with powers 360, 600, 900 W alternately fo...
