Cím:	The Significance of Forests and Algae in CO2 Balance : a Hungarian Case Study / Attila Bai, József Popp, Károly Pető, Irén Szőke, Mónika Harangi-Rákos, Zoltán Gabnai
Dátum:	2017
ISSN:	2071-1050
Megjegyzések:	This study presents the sequestration and emissions of forests and algae related to CO2 while providing a comparison to other biomass sources (arable crops, short rotation coppices). The goal of the paper is to analyze the impact of the current CO2 balance of forests and the future prospects for algae. Our calculations are based on data, not only from the literature but, in the case of algae, from our own previous experimental work. It was concluded that the CO2 sequestration and natural gas saving of forests is typically 3.78 times higher than the emissions resulting from the production technology and from the burning process. The economic and environmental protection-related efficiency operate in opposite directions. The CO2 sequestration ability of algae can primarily be utilized when connected to power plants. The optimal solution could be algae production integrated with biogas power plants, since plant sizes are smaller and algae may play a role, not only in the elimination of CO2 emissions and the utilization of heat but also in wastewater purification.

Cím:	An analysis of the demand-side, platform-based collaborative economy : Creation of a clear classification taxonomy / Tünde Zita Kovács, David Forest, Adrián Nagy, István Szűcs, András Nábrádi
Dátum:	2021
ISSN:	2071-1050
Megjegyzések:	The rapid proliferation of the demand-side, platform-based collaborative economy and its various forms have been an aspect of everyday life for over a decade. However, despite the platform's popularity, the descriptions and names attributed to the demand-side, platform-based collabora-tive economy are often used interchangeably and can be ambiguous, resulting in confusion among researchers and practitioners. This study examines the articles published during the pre-vious ten years, which have aimed not only to define but also to classify the collaborative economy according to various criteria. After reviewing the existing classification criteria, this ar-ticle presents a clearer taxonomy of the multiple forms of the collaborative economy by distin-guishing service providers' groups on their respective attributes. Our review and analysis have both theoretical and practical importance. Regarding the latter, our research will help managers and government officials alike in rethinking the taxation and subsidizing policies related to the various demand-side, platform-based collaborative economies and in preparing national and in-ternational consultations and conventions. This study aims to define the demand-side, plat-form-based collaborative economy and integrate the concept into various economic activities, providing a new and valuable contribution to the literature.

The Role Played by Trust and Its Effect on the Competiveness of Logistics Service Providers in Hungary / Oláh Judit, Bai Attila, Karmazin György, Balogh Péter, Popp József

Megjegyzések:

This research focuses on the role of trust and the impact of its level on the revenue, earnings before tax and the degree of flexibility of logistics service providers (LSPs). More specifically, the role of the executive manager is examined in relation to the impact of business relationships (trust levels) within and between organizations. In addition, the analysis covers the development of revenue, earnings before tax and degree of flexibility of logistics service providers in the context of the role of the head manager. The data were collected from 51 logistics service providers in Hungary. The results show that the level of trust established in the organization (with the employees, co-workers etc.) has a positive impact on the earnings before tax. Furthermore, this paper confirms that the trust executive managers establish around them is an important performance factor which even consumers perceive and that it has major significance in terms of degree of flexibility. This research further increases our understanding of the role and importance of trust as a strategic success factor for LSPs

Cím:	Change of real and simulated energy production of certain photovoltaic technologies in relation to orientation, tilt angle and dual-axis sun-tracking. A case study in Hungary / Henrik Zsiborács, Attila Bai, József Popp, Zoltán Gabnai, Béla Pályi, István Farkas, Nóra Hegedűsné Baranyai, Mihály Veszelka, László Zentkó, Gábor Pintér

Megjegyzések:	The aim of the study is to compare me tut angle-orientation and dual-axis tracking characteristics of mono- (m-Si), polycrystalline (p-Si), and amorphous silicon (a-Si) modules in the summer of 2017, under real meteorological conditions with simulated data. The most important new element of our study is that, besides a comparison of the three most significant photovoltaic types, the technologies are differentiated by examining specific energy generation using dual-axis tracking and four different orientations at 5-degree intervals compared to simulated values, near to the summer solstice. For these types of measurements, as far as we are aware, there is no previous reliable, well-supported, comparative data. The simulated data show less accurate results, proving the importance of real data. Based on simulated data, the tilt angle and orientation showed about 10% favorable values compared to reality. Knowing our results can make it easier to plan investment, and estimate the investment and operational costs and their return on crystalline and amorphous silicon solar modules, for both sun-tracking and fixed systems with various orientations and tilt angles.
