There are many studies that look into the relationship between public debt and economic growth. It is hard to find, however, research addressing the role of corruption between these two variables. Noticing this vacancy in current literature, we strive to investigate the effect of corruption on the relationship between public debt and economic growth. For this purpose, the pooled ordinary least squares (OLS), fixed effects models and the dynamic panel generalized method of moments (GMM) models (A

The idea of “green growth” has received international attention for more than a decade as a promising solution to a distinctly modern problem: a century of unparalleled increases in wealth based on equally unparalleled innovations in energy technology accompanied by global environmental threats such as climate change and persistent socioeconomic inequality. The green growth premise is that this problem can be solved without surrendering continued economic growth by a redirection of human effort

Decentralized energy systems have numerous advantages over mega energy projects, including environmental friendliness, lower upfront costs, greater affordability and reliability, lower risks, an easier ability to cope with system failures, and community empowerment. Despite these advantages, the type of governance used when constructing these systems can play an important role in yielding these positive impacts to local communities. This study investigates how renewable energy projects can fail

An emerging problem associated with the increased global demand for electric vehicles (EVs) is the post-use of lithium-ion batteries installed in them. Discarded batteries maintain 70–80% of their performance; thus, they are highly valuable recycling resources. Accordingly, technologies that complement the intermittency of renewable energy by integrating discarded EV batteries into battery energy storage systems (BESSs) are receiving attention. Here, the economic feasibility of a residential sol

The combination of building energy management technology and technology of the Fourth Industrial Revolution has a significant potential for reducing energy consumption and, hence, CO2 emissions. However, numerous studies have indicated barriers preventing market growth. These challenges are mainly attributed to characteristics of the ecosystem of the building energy management systems (BEMS) industry. Thisstudy aimed to identify the major challenges hindering the deployment of BEMS in combinatio

(1) Background: In this study, we introduce a manufacturable 32-channel cochlear electrode array. In contrast to conventional cochlear electrode arrays manufactured by manual processes that consist of electrode-wire welding, the placement of each electrode, and silicone molding over wired structures, the proposed cochlear electrode array is manufactured by semi-automated laser micro-structuring and a mass-produced layer-by-layer silicone deposition scheme similar to the semiconductor fabrication

To investigate the neuronal visual encoding process in the retina, researchers have performed in vitro and ex vivo electrophysiological experiments using animal retinal tissues. The microelectrode array (MEA) has become a key component in retinal experiments because it enables simultaneous neural recording from a population of retinal neurons. However, in most retinal experiments, it is inevitable that the retinal tissue is flattened on the planar MEA, becoming deformed from the original hemisph

Abstract The purpose of this article is to examine the Korean photovoltaic (PV) R&D strategy and its effectiveness in helping Korean manufacturer competitiveness. The article reviewed the Korean government's PV R&D funding from 2008 to 2017 and investigated the technology readiness levels of 298 R&D projects funded by the Korean government during the same period. It is found that the Korean government followed a two‐track approach of nurturing commercialization technology to cope wit

This study investigates the factors that affect the investment environment of the renewable energy industry in emerging countries, and quantifies them to derive relative priorities, drawing on the Vietnamese solar market as a critical case. Vietnam's solar photovoltaic (PV) market was exposed to various adverse policy situations during 2017–2019. The priorities of the determinant factors were derived using analytic hierarchy process analysis, based on a survey of 20 energy experts. The priority

"This dissertation seeks to clarify the appropriate economic development paradigm that can be applied to solve diverse challenges and crises bedeviling modern global society. These crises include climate change, environmental degradation, resource depletion, stagnation in growth, widening inequality gap between the rich and the poor leading to social polarization, and the deterioration in quality of life, among others. Global society including leading international agencies and inter-governmenta
