Abstract

Purpose

The purpose of this paper is to present the power noise characteristics of a multilayer printed circuit board (PCB) in which discrete capacitors have been embedded.

Design/methodology/approach

Embedded technology has been implemented on a multilayer PCB to enhance the performance and functionality and to decrease the power noise. Decoupling capacitors were directly positioned on the inner power planes of a board, which resulted in low‐loop inductance through the minimized length of the interconnection from the chips to the PCB's power delivery network.

Findings

A low‐noise PCB was successfully designed and fabricated using an embedding process for the discrete decoupling capacitors. It was demonstrated that such an approach offers lower interconnection inductance and quiet noise performance, including highly efficient propagation noise suppression at wideband frequencies.

Research limitations/implications

Most conventional simulation techniques offer expectations for the signal characteristics on the time domain to minimize bit error rates in application systems. Further development work will focus on the integrated simulation models including the equivalent circuits for the transmission line and power noise effects to improve the accuracy of the signal performance.

Originality/value

This paper presents a new approach for improving generating and propagating noise performance through the use of an embedded decoupling capacitor design methodology.

Abstract

Purpose

The purpose of this paper is to review the current status of collaboration in cultural heritage preservation in East Asia, including digital projects, and to suggest practical improvements based on a cultural structuralism perspective.

Design/methodology/approach

Through exploratory research, the paper addresses aspects for successful collaboration in cultural heritage digitisation in East Asia.

Findings

The paper indicates the difference in collaboration of cultural heritage digitisation between regions such as Europe and the unique situation in East Asia.

Social implications

If collaboration between the countries of East Asia was implemented then such a community could deal with the issues of cultural heritage by having a standard scheme or policy.

Originality/value

There has been little literature published on East Asian cultural heritage initiatives, particularly in the area of digitisation and digital preservation.

Abstract

Purpose

Successful social marketing campaign to promote COVID-19 vaccination for the unvaccinated relies on increasing positive reactions but also reducing negative responses to persuasive messages. This study aims to investigate the relative effects of narrative vs non-narrative public service announcements (PSAs) promoting COVID-19 vaccination on both positive and negative reactions. Using social media as a tool for disseminating marketing campaigns provides a great opportunity to examine the effectiveness of narrative PSAs on vaccination intention, especially among unvaccinated young adults, who were the target audience of the social marketing. This study explores the role of empathy and psychological reactance as underlying mechanisms.

Design/methodology/approach

An experiment involving unvaccinated young adults was conducted with a one-factor, two-condition (message type: narrative vs non-narrative) design.

Findings

Results indicated that the narrative (vs non-narrative) PSAs led to greater empathy. While no direct effects of message type emerged on psychological reactance or vaccination intention, results of a serial multi-mediator model confirmed that empathy and psychological reactance mediated the effects of message type on vaccination intention.

Originality/value

The study extends the understanding of narrative persuasion by examining an underlying mechanism behind narrative persuasion in a COVID-19 PSA. This study provides empirical evidence of the important role of empathy in processing narrative PSAs. Moreover, the current study expands narrative persuasion’s applicability to COVID-19 vaccination intervention messages for unvaccinated young adults, highlighting the effectiveness of narrative persuasion as a social marketing communication tool.

Abstract

This study aims to explore the underlying patterns in tax innovation. Prior studies of local sales taxes still leave a gap in the literature and render the results inconclusive because the studies cover either state level or localities within a single state for a short period. To cover the gap, we assemble a dataset of counties in all states for FY1970-2006 but focus on 12 states not threatened by intra-jurisdictional competition. Our empirical analyses yield evidence that a county adopts local sales tax for political and economic rationale rather than fiscal condition. Accordingly, regional diffusion has positive effects on local sales tax adoption in a county. These findings contribute substantively to sales tax literature while confirming policy diffusion.

Abstract

Purpose

Accurate and timely foresight of future trends and changes in science and technology (S&T) is a key to national competitiveness. The purpose of this paper is to describe recent technological foresight conducted by the Technology Foresight Center at the Korea Institute of Science and Technology Evaluation and Planning. The authors also address current issues and problems encountered in the process of technology foresight (TF) in Korea.

Design/methodology/approach

The authors used TF methodologies which included bibliometrics, expert panels, SWOT analysis, and conferences/seminars.

Findings

The authors derived 20 future issues and 40 future needs in S&T from the five areas of global mega trends; then 200 future technologies were suggested with a time horizon of 40 years, from 2010 to 2050, for solving those future issues and needs. Finally, the authors suggested outlooks for technological development in the years 2020 and 2050.

Research limitations/implications

It is time to evaluate Korean TF exercises which were started 15 years ago. The evaluation of TF will help guide TF and inform policy and decision makers.

Practical implications

The findings can help policy makers shape future governmental S&T policy in Korea. The final result of this work was applied to the second S&T Framework Plan in Korea, in which 90 technologies were identified as national key technologies for the next five years, from 2008 to 2012.

Originality/value

To the best of the authors' knowledge, there are no studies suggesting not only future technologies based on solving future issues and needs but also outlooks for technology development in the years 2020 and 2050.

This paper aims to link location choice and ownership structure to the debate on the multinationality–performance relationship.

Abstract

Purpose

This paper aims to link location choice and ownership structure to the debate on the multinationality–performance relationship.

Design/methodology/approach

This paper draws on a panel data set that covers 1,321 emerging economy multinational enterprises (EMNEs) and includes 4,227 observations from 44 emerging economies between 2004 and, 2013.

Findings

The empirical results find that multinationality has a positive effect on EMNEs’ performance, and that this positive effect is larger for their investments in developed countries than in developing countries. The study also finds that this positive effect of foreign operation in developed countries switch to negative at higher levels of multinationality for privately owned EMNEs than for state-owned EMNEs.

Originality/value

This paper provides new empirical evidence to support an institutional perspective of the internationalisation of EMNEs that are investing in developed countries, contributing to the multinationality-performance literature, highlighting the importance of foreign direct investment location decision and ownership structure.
