Purpose - Supply chain disruptions have plagued firms since the advent of COVID-19 lockdowns. As a result, supply chains remain unstable and dynamic. To better understand supply chain management during periods of disruption, this study compares the impact of relational capital on ambidextrous innovation and firm performance between Korean and U.S firms. Design/Methodology/Approach - This study includes a sample of 200 Korean firms and 227 U.S firms. PLS-SEM is the statistical tool utilized with MICOM multigroup analysis. Findings - Korean and U.S. firms were found to be different on three different pathways indicating that open innovation and investment in supplier relations improve supply chain disruption orientation, exploration innovation, and firm performance Research Implications - Relationship capital can significantly improve supply chain management, innovation, and firm performance. Exploitation innovation is better for enhancing supply chain management in the short-term amid interruptions.

Purpose – Supply chain disruptions have dominated business planning and performance since the beginning of the COVID-19 pandemic and continue to mar organizations through 2022. This research carefully examines the role of organizational culture in developing both supply chain resilience and market performance amid supply chain disruptions. Design/Methodology/Approach – An empirical study of over 200 South Korean firms were tested. The model is tested using PLS-SEM; furthermore, mediation effects enrich the quality of the findings. This research is framed utilizing the stimulus-organism-response model; thus, emphasizing the highly dynamic business environment that has ensued. Findings – The research confirms that supply chain disruption orientation, a strategic orientation and a proxy for a well-prepared organizational culture, leads to both supply chain resilience and market performance. Results also confirm that resilience reinforces market performance throughout the supply chain. Study contributions suggest that firms should consider themselves as organisms within a highly dynamic environment and develop a highly prepared organizational culture in order to bolster supply chain resilience and market performance. Research Implications – Scholars can further employ the stimulus-organism-response model in firm-level research and further study the link between organizational culture and supply chain performance amid COVID-19. Finally, the results of this research provide guidelines for organizations when they decide on operational procedures during the pandemic, as they aim to produce greater returns for their ventures.
ALMA Reveals Transition of Polarization Pattern with Wavelength in HL Tau’s Disk
Stephens, Ian W.,Yang, Haifeng,Li, Zhi-Yun,Looney, Leslie W.,Kataoka, Akimasa,Kwon, Woojin,Ferná,ndez-Ló,pez, Manuel,Hull, Charles L. H.,Hughes, Meredith,Segura-Cox, Dominique,Mundy, Lee,C American Astronomical Society 2017 The Astrophysical journal Vol.851 No.1
<P>The mechanism for producing polarized emission from protostellar disks at (sub) millimeter wavelengths is currently uncertain. Classically, polarization is expected from non-spherical grains aligned with the magnetic field. Recently, two alternatives have been suggested. One polarization mechanism is caused by self-scattering from dust grains of sizes comparable with the wavelength, while the other mechanism is due to grains aligned with their short axes along the direction of radiation anisotropy. The latter has recently been shown as a likely mechanism for causing the dust polarization detected in HL. Tau at 3.1 mm. In this paper, we present ALMA polarization observations of HL. Tau for two more wavelengths: 870 mu m and 1.3 mm. The morphology at 870 mu m matches the expectation for self-scattering, while that at 1.3 mm shows a mix between self-scattering and grains aligned with the radiation anisotropy. The observations cast doubt on the ability of (sub) millimeter continuum polarization to probe disk magnetic fields for at least HL Tau. By showing two distinct polarization morphologies at 870 mu m and 3.1 mm and a transition between the two at 1.3 mm, this paper provides definitive evidence that the dominant (sub) millimeter polarization mechanism transitions with wavelength. In addition, if the polarization at 870 mu m is due to scattering, the lack of polarization asymmetry along the minor axis of the inclined disk implies that the large grains responsible for the scattering have already settled into a geometrically thin layer, and the presence of asymmetry along the major axis indicates that the HL Tau disk is not completely axisymmetric.</P>
Three Reforming Regimes? Modernity and the Fiscal State in Modern Korean History
Holly Stephens 서울대학교 규장각한국학연구원 2019 Seoul journal of Korean studies Vol.32 No.1
This article approaches the challenge of reperiodizing Korean history by considering the place of the nineteenth century within accounts of modern Korea. In recent years, numerous studies have examined various aspects of Korean “modernity.” However, notwithstanding the contributions from such studies, an overemphasis on modernity as a central concept runs the risk of marginalizing significant topics that fall outside of the definition of “modern” life. After exploring recent historiographical trends, this article presents an alternative conception of the nineteenth and twentieth centuries that explicitly aims to look beyond the category of “the modern” in order to bridge the historiographical divide of late Chosŏn and colonial Korea. Through a survey of fiscal practices under three different regimes—the late Chosŏn state, the era of the Kabo reforms and the Great Korean Empire, and the colonial period—I examine the evolution of taxation as a measure of the state’s ability to access information and negotiate with competing interests within Korean society. Rather than focusing on an emerging modern rationality, I show how the practices adopted by different regimes appealed to a wide array of norms as each government confronted shared fiscal concerns and sought to cultivate the information and institutions necessary to support itself. Despite some obvious innovations, I also show some continuities that highlight the importance of the nineteenth century in understanding interactions between the population and the government into the twentieth century.
