IntroductIon The chief executive officer of a company is responsible for a long list of decisions that impact corporate performance, including strategy, organizational design, and incentives. He or she also brings to bear a managerial and leadership style that has a considerable influence on workplace productivity and culture. As such, many believe that the selection of the CEO is the single mo...

This paper extends the investigation of the effect of managerial motives on hedging policy. I utilize a proxy variable that incorporates CEO incentives to increase risk relative to incentives to increase stock price. The variable is directly measured using observed characteristics of CEO portfolios of stock and option holdings. Furthermore, CEO risk-taking incentives are modeled as a choice var...

The aim of this paper is to discuss the effect of corporate governance mechanisms on controlling CEOs’ emotions and some behavioral biases. Departing from a sample of 40 public traded Tunisian firms, we test the impact of the board of directors on managing CEO’s irrationalities. Our results highlight strong evidence on the role of the board characteristics, especially the board independence, a ...

The impact of microwave roasting cocoa beans on the aroma and phytochemical profile dark chocolates (70% cocoa) was studied. Three produced from roasted (450 W–55 min, 600 W–35 900 W–20 min) were compared with a chocolate convectively (130 °C–30 min). Aroma analysis via HS-SPME-GC-MS indicated that resulted in distinctive profile, to beans. Increased power input seems main inducer elevated leve...

The crystal habit of stishovite changes with the temperature of crystallization at a pressure of about 120 kb. Below 600 degrees C it is bipyramidal; between 600 degrees and 900 degrees C it is granular; and above 900 degrees C it is acicular. This temperature dependence of the crystal habit of stishovite may constitute a highpressure geological thermometer which could indicate limiting values ...

The system (1 – x)NiIn2S4 xNiIn2Se4 has been investigated by X-ray powder methods. The subsolidus phase diagram is constructed in the temperature interval 600 -1000 þC. The spinel type NiIn2S4 exhibits a phase width up to the composition NiIn2S2Se2 at 900 þC and NiIn2S2:8Se1:2 at 600 þC. A new layered compound is formed for 0.7 ÿ xÿ 0.5 at 600 þC and for x = 0.6 at 900 þC which crystallizes in ...
