Who Lobbies and When: Analyzing Patterns of Foreign Lobbying

My dissertation ``Who Lobbies and When: Analyzing Patterns of Foreign Lobbying Activities" studies (a) who lobbies, (b) for what purposes, and (c) when. Foreign lobbying involves a wide set of actions that foreign governments, firms, interest groups, and individuals take to pursue their interests and interact with diverse actors in other states. Like diplomacy, foreign lobbying aims to facilitate interstate interaction and help actors achieve their international goals. Yet, since not only governments but also firms and interest groups can engage in lobbying and choose lobbying topics and tactics, I suggest foreign lobbying as a more versatile, alternative form of diplomacy. The United States, as the global superpower, has experienced nearly 53,000 lobbying incidents conducted by foreign actors from about 250 countries since 1971. However, despite the prevalence and persistence of foreign lobbying activities, we have scant knowledge about the basics of foreign lobbying. The lack of theoretical and empirical understanding of foreign lobbying activities motivated my dissertation. What is foreign lobbying? What are the patterns of foreign lobbying activities? The dissertation provides systematic information on foreign lobbying activities and examines the conditions that affect lobbying patterns. Chapter 1 discusses the dissertation's research questions, findings, and contributions. Chapter 2 introduces my original Foreign Lobbying Dataset (FOLD), which records the number of lobbying activities between 1971-2017 classified by principal type, topic, and tactic at the country-year level. Chapters 3 and 4 examine how international institutions influence foreign actors' incentives for lobbying. By showing the positive and significant association between a country's lobbying activities and its linkages with the United States through international institutions, Chapter 3 finds that foreign actors resort to lobbying as a complement to facilitate institutions' objectives. Chapter 4 examines the relationship between Free Trade Agreement negotiation process and the timing of foreign lobbying activities.  The significant increase in foreign lobbying activities, particularly by foreign governments, from two years before FTA signing and until entry into force implies that actors utilize lobbying to influence the design and implementation of FTAs. Both empirical chapters highlight the value of foreign lobbying as a complementary diplomatic instrument compatible with formal international institutions

Effects Of HPWSS On Employee’ Attitude For Korean Firms: The Mediating Role Of Human Resource Competency And The Moderating Role Of Organization Culture

The purpose of this paper is to examine the black box by which high performance work systems (HPWSs) affect employee’s attitude. It attempts to show the mediating effect of human resource (HR) competency in the HPWSs-job attitude link, and the moderating effect of organization culture. More specifically, we propose that HPWSs have a positive effect on the both job satisfaction and HR competency, and that HR competency mediates the relationship between HPWSs and job satisfaction. Further, we propose that adhocracy culture in organization strengthens such relationships between HPWSs and HR competency as well as between HPWSs and job satisfaction. We use a nationally representative data set from Korea (firm-level samples: 215 firms, employee-level samples: 5577 employees) for testing the hypotheses. Results indicated support for the hypothesized that positive association between HPWSs and HR competency and between HPWSs and job satisfaction. HR competency has a partial mediating effect in the HPWS-job attitude link. The results were supportive of organization culture of the impact of HPWSs on HR competency and job satisfaction. Limitations of the study and implications for future research are discussed.

Properties of Microlensing Central Perturbations by Planets in Binary Stellar Systems under the Strong Finite-Source Effect

We investigate high-magnification events caused by planets in wide binary stellar systems under the strong finite-source effect, where the planet orbits one of the companions. From this, we find that the pattern of central perturbations in triple lens systems commonly appears as a combination of individual characteristic patterns of planetary and binary lens systems in a certain range where the sizes of the caustics induced by a planet and a binary companion are comparable, and the range changes with the mass ratio of the planet to the planet-hosting star. Specially, we find that because of this central perturbation pattern, the characteristic feature of high-magnification events caused by the triple lens systems appears in the residual from the single-lensing light curve despite the strong finite-source effect, and it is discriminated from those of the planetary and binary lensing events and thus can be used for the identification of the existence of both planet and binary companion. This characteristic feature is a simultaneous appearance of two features. First, double negative-spike and single positive-spike features caused by the binary companion appear together in the residual, where the double negative spike occurs at both moments when the source enters and exits the caustic center and the single positive spike occurs at the moment just before the source enters into or just after the source exits from the caustic center. Second, the magnification excess before or after the single positive-spike feature is positive due to the planet, and the positive excess has a remarkable increasing or decreasing pattern depending on the source trajectory.Comment: 12 pages, 3 figures, accepted for publication in Ap

Status of MgB2 superconducting wires at Sam Dong

MgB2 superconducting wires have remarkable potential as cost-effective materials for transformers, generators, power transmission, and superconducting magnetic energy storage to enable highly efficient power-grid networks for sustainable development. Herein, we report multifilamentary MgB2 wires with variously designed architectures that have been developed by Sam Dong Co., Ltd. The customized manufacturing process can also produce long-length pieces up to 3 km in length, indispensable in constructing large-scale devices, including cables. Based on this progress, we will continue to develop high-performance MgB2 wires and related superconducting technologies
