ABSTRACT
This study examines the impact of two critical events, the introduction of Bitcoin futures and the COVID-19 pandemic, on Bitcoin's returns and volatility. We find that the inception of Bitcoin futures (positively) impacts its returns in the spot market while no significant interaction occurs for volatilities. The pandemic does not seem to influence Bitcoin's returns or volatility, which is consistent with the notion that Bitcoin is insulated from some global economic developments. Our tests also reveal that Bitcoin spot prices dominate its futures. This information might be useful for investors in capturing trend reversals considering the order of information disseminated. © 2023 Elsevier Inc.
ABSTRACT
Purpose: This study aims to investigate the working way of the e-Pulse portal in Turkiye as a sample of a next-generation digital tool for health data management. Accordingly, this study focuses on explaining the structure and key services of the e-Pulse portal in the context of health data management. Design/methodology/approach: This study is a technical paper that will explain how the e-Pulse portal works in Turkiye. Accordingly, the data are based on secondary sources and mostly the official website of the e-Pulse portal. As a sample case, this study investigates the e-Pulse portal from Turkiye. The data are categorized by tables, and some key factors are classified based on review results. Finding(s): As a result of the review of the e-Pulse portal's sample account, it is seen that the e-Pulse portal provides comprehensive data for personal health data for both individuals and healthcare professionals. By permitting healthcare professionals, users or patients can share their personal health data on specific dates and numbers whenever they need and want. When sharing recorded personal health data, citizens or patients can get more efficient healthcare service on the time. Research limitations/implications: By giving descriptive evidence and review through the e-Pulse portal, countries with high-populated can see the key e-services and elements to manage health data through digital tools. On the other side, this study has some limitations. This study investigated the e-Pulse portal and its e-services for Turkiye and gave some findings mostly based on subjective deduction. Another digital portal can give different findings for the literature. Practical implications: Based on the e-Pulse portal case, it is determined that by creating a digital portal with recorded personal up-to-date health data, healthcare services can be ensured more efficiently among high-populated countries in the long term. While population growth and pandemic possibilities such as COVID-19 increase throughout the world, serving more patients with these portals will increase efficiency and service quality, provided that patient information is well protected. Originality/value: This study reveals key e-services and segments to provide personal health data management by a next-generation digital tool based on the e-Pulse portal. The main contribution of this study is expected to guide other countries when adapting next-generation technology or systems to manage health data in the future.Copyright © 2023, Emerald Publishing Limited.
ABSTRACT
Aim: The recent macroeconomic problems in the global economy are highly related to the coronavirus disease 2019 (COVID-19) pandemic. Since the highest spread of the disease is observed in the European countries, it is worthwhile to investigate the macroeconomic indicators in the European Union (EU) member and the candidate countries. Inflation is one of the most important indicators to examine since it may directly affect many macroeconomic variables. In this study, the determinants of inflation in the 28 EU members and candidate states are investigated. Material and Methods: In this study, the determinants of inflation in the 28 EU members and candidate states are investigated for January 2020-July 2020 using spatial panel data analysis. Results: The empirical results indicated that the exchange rate and money supply ratios were reasons of the increase in inflation. There is also increasing pressure on the inflation rates due to the domestic money supply and exchange rate variables as well as the neighborhood relations between countries (positive spatial effects). Conclusion: It is an important finding that macroeconomic problems in each sample country are also affected by developments in neighboring countries as well as internal dynamics. Continuous development of economic, social, and political cooperation between neighboring countries at the regional level is essential. It is reasonable for every country to develop self-sufficient strategies in the fields of agriculture, food, technology, and pharmaceutical industries in case of global disasters. Regional cooperation should not be limited to the development of sectors that stand out during the pandemic period. © 2020, Duzce University Medical School. All rights reserved.
