Facebook has been identified as a primary source of political information by a majority (63 percent) of its users. The purpose of this paper is to examine the relationship between Facebook use and political participation, and investigate the mediating effects of the characteristics of one’s Facebook network (i.e. network size, proportion of strong ties, and discussion network heterogeneity).

This study relies on a representative survey of American adults (n=1,032) conducted during the 2012 primary election campaigns from May 3 to May 10. The sample was randomly selected from a representative online panel maintained by a professional research organization. Given this study’s focus on the influence of Facebook use and network characteristics, an online panel is suitable for testing the hypotheses.

The results show positive associations between Facebook use and both off- and online political participation. Further, the positive association between Facebook use and political participation is mediated by discussion network heterogeneity and the proportion of strong ties in one’s Facebook network, but not the network size.

This study sheds light on the roles played by network characteristics of Facebook. The composition of a user’s Facebook network is closely related with what kind of information she encounters and how likely she is to participate in politics. Hence, network characteristics (e.g. Facebook discussion network heterogeneity) arise as important for gaining a nuanced understanding of the relationship between general use of the medium and its political outcomes.

The purpose of this paper is to demonstrate whether or not public relations efforts in corporate social responsibility (CSR) influence the news media in corporate crisis situations.

The study conducted a content analysis of press releases and news media based on traditional human-coded cross-lag analyses and a machine learning technique, a novel method of big data analysis to test hypotheses.

Results indicate that CSR press releases indeed influenced the news media. During the crisis point, however, agenda-building was not observed.

Corporations need to continue CSR activities and provide public relations materials consistently even after a crisis, as an agenda-building role could be recovered.

The study examines the relationship between CSR and crisis situations in an agenda-building theoretical framework. The authors introduce agenda-building in the corporate sector with machine learning techniques.

This chapter focuses on South Korea’s newly found regional leadership, as the emergent middle power of East Asia, in order to advance regional integration and institution-building. Policy leadership is observed and analyzed from an international lens, linked to the literature of middle powers. The chapter first conceptualizes middle powers in connection with the issue of international leadership, since such states often play important roles in promoting cooperation. The chapter looks especially into South Korea’s foreign policy behavior toward East Asian regional processes and how it has manifested innovative and capable leadership. More specifically, the last three presidencies of Kim Dae-jung (1998–2002), Roh Moo-hyun (2003–2008), and Lee Myung-bak (2008–2013) are scrutinized in the hope of underscoring how their particular administrations, political leadership, and strategic approaches to foreign policy toward the region influenced South Korea’s regional leadership attempts and middle power status.

This paper investigates a retrospective on the Journal of Derivatives and Quantitative Studies (JDQS) on its 30th anniversary based on bibliometric. JDQSs yearly publications, citations, impact factors, and centrality indices grew up in early 2010s, and diminished in 2020. Keyword network analysis reveals the JDQS's main keywords including behavioral finance, implied volatility, information asymmetry, price discovery, KOSPI200 futures, volatility, and KOSPI200 options. Citations of JDQS articles are mainly driven by article age, demeaned age squared, conference, nonacademic authors and language. In comparison between number of views and downloads for JDQS articles, we find that recent changes in publisher and editorial and publishing policies have increased visibility of JDQS.

This paper aims to discuss the profiles of Korean chaebols involved in global electronics

The research was conducted among 132 of their Korean suppliers, with linked in‐depth interviews with chaebol managers. From an initial set of literature‐based variables, factor analysis is used to generate six chaebol characteristics, which are then correlated with four chaebol‐supplier relationship outcomes.

“Decision making” and “social exchange”, in particular, are found to correlate positively with all four chaebol‐supplier relationship outcome measures, relationship satisfaction, performance, cooperation and conflict resolution. “Partnership” is associated positively with three of these outcomes, and “strategy‐longevity” with relationship satisfaction. The chaebols' “structure‐control” and “leadership” are not found to be predictors of successful relationship outcomes as measured in this study. A combination of higher quality, lower cost products with linkages to a foundation of decision making, social exchange, partnership and strategy‐longevity appears to be a potent mix for global players.

The paper provides the underpinnings of the marketing strategy and component strategy profiles of a number of major Korean multinationals in the belief that they would inform western relationship marketing strategies.

Unmanned aerial vehicles (UAV), colloquially called drones, are widely applied in many sectors of the economy, including the construction industry. They are used for building inspections, damage assessment, land measurements, safety inspections, monitoring the progress of works, and others.

The study notes that UAV pose new, and not yet present, risks in the construction industry. New threats arise, among others, from the development of new technologies, as well as from the continuous automation and robotization of the construction industry. Education regarding the safe use of UAV and the proper use of drones has a chance to improve the safety of work when using these devices.

The procedure (protocol) was developed for the correct and safe preparation and planning of an unmanned aerial vehicle flight during construction operations.

Based on the analysis of available sources, no such complete procedure has yet been developed for the correct, i.e. compliant with applicable legal regulations and occupational health and safety issues, preparation for flying UAV. The verification and validation of the developed flight protocol was performed on a sample of over 100 different flight operations.

In parallel sampling method, the size of the sampling capacitor is reduced to improve the bandwidth of the ADC.

Various low-power techniques for 10-bit 200MS/s pipelined analog-to-digital converter (ADC) are presented. This work comprises two techniques including parallel sampling and switched op-amp sharing technique.

This paper aims to study the effect of parallel sampling and switched op-amp sharing techniques on power consumption in pipelined ADC. In switched op-amp sharing technique, the numbers of op-amps used in the stages are reduced. Because of the reduction in the size of capacitors in parallel sampling technique and op-amps in the switched op-amp sharing technique, the power consumption of the proposed pipelined ADC is reduced to a greater extent.

Simulated the 10-bit 200MS/s pipelined ADC with complementary metal oxide semiconductor process and the simulation results shows a maximum differential non-linearity of +0.31/−0.31 LSB and the maximum integral non-linearity (of +0.74/−0.74 LSB with 62.9 dB SFDR, 55.90 dB SNDR and ENOB of 8.99 bits, respectively, for 18mW power consumption with the supply voltage of 1.8 V.
