Organizational Learning and the Learning Organization: A Dichotomy Between Descriptive and Prescriptive Research

Abstract: Despite the growing popularity of the term 'organizational learning," writings on the topic have little consensus in terms of definition, perspective, conceptualization, and methodology. This article examines the dichotomy between two main streams of theorizing in the field. The first stream, prescriptive writings on the learning organization, is concerned with the question "How should an organization learn?" Targeting practitioners, these studies are usually based on the authors' consulting experience and seldom follow rigorous research methodologies. They also tend to overgeneralize their theories to all types of organization. Descriptive researches on organizational learning fall in the second stream which tackles the question "How does an organization learn?" These are academic studies striving for scientific rigor. Nevertheless, they often fail to generate useful implications for practitioners. In the final section of the article, brief suggestions are made to integrate the two streams of research.

Tunneling or Value Addition? Evidence from Mergers by Korean Business Groups

Abstract: Business groups in emerging markets have the potential to create either value or agency problems. Using Korean mergers, we investigate the nature of business groups in emerging markets and examine whether Korean business groups (chaebols) add value to their member firms or provide the controlling shareholders with an opportunity for wealth transfer (tunneling). We show that chaebol-affiliated firms that performed well prior to the merger realize significantly negative announcement returns. We also find that chaebol bidders who acquired poorly performing targets within the same group and/or had concentrated equity ownership by owner-managers experience significantly negative abnormal returns. These types of mergers, however, have a significantly positive effect on the market value of the portfolio of other firms in the group. Our results support the tunneling view that firms belonging to business groups pay less attention to the maximization of individual firm value and make takeover decisions that are beneficial to only controlling shareholders.

Single-Layer MoS2-Based Nanoprobes for Homogeneous Detection of Biomolecules

Abstract: A single-layer MoS2 nanosheet exhibits high fluorescence quenching ability and different affinity toward ssDNA versus dsDNA. As a proof of concept, the MoS2 nanosheet has been successfully used as a sensing platform for the detection of DNA and small molecules.
