Information Technology and Organizational Learning: An Investigation of Exploration and Exploitation Processes

Abstract: This study investigates the effects of information technology (IT) on exploration and exploitation in organizational learning (OL). We use qualitative evidence from previously published case studies of a single organization to extend an earlier computational model of organizational learning (March 1991) by introducing IT-enabled learning mechanisms: communication technology (e-mail), knowledge repositories of best practices, and groupware. We find that each of these IT-enabled learning mechanisms enable capabilities that have a distinct effect on the exploration and exploitation learning dynamics in the organization. We also find that this effect is dependent on organizational and environmental conditions, as well as on the interaction effects between the various mechanisms when used in combination with one another. We explore the implications of our results for the use of IT to support organizational learning.

The Myth of Diffuse Ownership in the United States

Abstract: This article offers evidence on the ownership concentration at a representative sample of U.S. public firms. Ninety-six percent of these firms have blockholders; these blockholders in aggregate own an average 39% of the common stock. The ownership of U.S. firms is similar to and by some measures more concentrated than the ownership of firms in other countries. These findings challenge current thinking on a number of issues, ranging from the nature of the agency conflict in domestic corporations to the relationship between ownership concentration and legal protections for investors around the world.

Academic-practitioner collaboration need not require joint or relevant research: Toward a relational scholarship of integration.

Abstract: The article examines how management science researchers and academics might more fruitfully collaborate with actual managers. The two groups are separated by, among many other things, the language ...

Cash Holdings and Corporate Diversification

Abstract: This paper studies the relation between corporate liquidity and diversification. The key finding is that multi-division firms hold significantly less cash than standalone firms because they are diversified in their investment opportunities. Lower cross-divisional correlations in investment opportunity and higher correlations between investment opportunity and cash flow correspond to lower cash holdings, even after controlling for cash-flow volatility. The effects are strongest in financially constrained firms and in well-governed firms, and correspond to efficient fund transfers from low- to high-productivity divisions. Taken together, these results bring forth an efficient link between diversification in investment opportunity and corporate liquidity.

Enhanced thermal conductivity and viscosity of copper nanoparticles in ethylene glycol nanofluid

Abstract: This study investigates the thermal conductivity and viscosity of copper nanoparticles in ethylene glycol. The nanofluid was prepared by synthesizing copper nanoparticles using a chemical reduction method, with water as the solvent, and then dispersing them in ethylene glycol using a sonicator. Volume loadings of up to 2% were prepared. The measured increase in thermal conductivity was twice the value predicted by the Maxwell effective medium theory. The increase in viscosity was about four times of that predicted by the Einstein law of viscosity. Analytical calculations suggest that this nanofluid would not be beneficial as a coolant in heat exchangers without changing the tube diameter. However, increasing the tube diameter to exploit the increased thermal conductivity of the nanofluid can lead to better thermal performance.
