Neoanthropocene Raising and Protection of Natural and Cultural Heritage: A Case Study in Southern Italy
2020
Analyzing the human history on the planet, a conflictual relation was raised when humankind had started destroying the natural ecosystem and biota, and consequently, a capacity to induce environmental change has increased throughout human history in the so-called Anthropocene age. A 'noosphere'-centered civilization could produce a non-disruptive new kind of anthropocentrism. This is becoming a new context to define Neoanthropocene based on a renewed homeostatic relationship between Earth and mankind. The potential application of this theoretical approach has been tested in drafting steps of Plan of Lucania Apennines, Valdagri, and Lagonegrese National Park, in southern Italy. Drafting the …
Mobility Patterns and Mode Choice Preferences during the COVID-19 Situation
2022
The empirical research on the COVID-19 epidemic’s consequences suggests a major drop in human mobility and a significant shift in travel patterns across all forms of transportation. We can observe a shift from public transport and an increase in car use, and in some cases also increase of cycling and (less often) walking. Furthermore, it seems that micromobility and, more generally, environmentally friendly and comanaged mobility (including shared services), are gaining ground. In previous research, much attention was paid to the mode choice preferences during lockdown, or early stages of the SARS-CoV-2 situation. The blind spot, and aim of this work, is how long observed changes in mode ch…
The New Era of Business Digitization through the Implementation of 5G Technology in Romania
2021
The main objective of the present research is to identify the advantages and benefits that the use and implementation of 5G technology has on the development and evolution of the Romanian business environment. The study is based on a theoretical documentation regarding existing information in the field and a descriptive analysis of the evolution of the technology in Romania and worldwide. The research method chosen is a survey based on an opinion poll (questionnaire) to find out the availability of economic entities regarding the implementation of 5G technologies, the foreseen expectations and those realized by the business environment regarding the effects of 5G technologies on the economi…
David against Goliath: Diagnosis and Strategies for a Niche Sport to Develop a Sustainable Fan Community
2021
Pilota, played using the hands, is a niche sport with origins dating back to Greco-Roman times. In the Valencian region of Spain, an indigenous version of the sport is played with healthy participation rates despite having to compete with the major global sports. This study is aimed at understanding the current situation of this sport in terms of knowledge, transmission channels, fan experience and media consumption, as well as the brand strategy challenges it faces for building a stable and sustainable fan community. The methodology consists of a combination of quantitative and qualitative techniques. Nearly 1500questionnaires completed across three study universes, four focus groups and 3…
Gender Differences in the Relationship between Work–Life Balance, Career Opportunities and General Health Perception
2021
Although gender equality is increasingly promoted both in the workplace and in society, and women have now fully entered the workforce, the issue of gender differences in relation to career advancement still seems open. Although gender roles no longer clearly define who is responsible for home care and who is responsible for job duties, some research shows that the conflict between family and work life appears to be a greater problem for women than for men. The aim of this study was to examine the relationship between career opportunities, work–life balance, and well-being perception separately in both female (n = 499) and male (n = 557) respondents in order to shed light on the role …
Space Thermoacoustic Radioisotopic Power System, SpaceTRIPS: The Magnetohydrodynamic Generator
2021
Electricity production is a major problem for deep space exploration. The possibility of using radioisotope elements with a very long life as an energy source was investigated in the framework of an EU project “SpaceTRIPS”. For this, a two-stage system was tested, the first in which thermal energy is converted into mechanical energy by means of a thermoacoustic process, and the second where mechanical energy is converted into electrical energy by means of a magnetohydrodynamic generator (MHD). The aim of the present study is to develop an analytical model of the MHD generator. A one-dimensional model is developed and presented that allows us to evaluate the behavior of the device as regards…
Life Cycle Environmental Impacts and Health Effects of Protein-Rich Food as Meat Alternatives: A Review
2022
The food sector is responsible for a considerable impact on the environment in most environmental contexts: the food supply chain causes greenhouse gas emissions, water consumption, reduction in cultivable land, and other environmental impacts. Thus, a change in food supply is required to reduce the environmental impacts caused by the food supply chain and to meet the increasing demand for sufficient and qualitative nutrition. Large herds of livestock are inappropriate to achieve these goals due to the relevant impact of meat supply chain on the environment, e.g., the land used to grow feed for animals is eight times more than that for human nutrition. The search for meat alternatives, espe…
Use of Sentinel-2 Satellite for Spatially Variable Rate Fertiliser Management in a Sicilian Vineyard
2022
Satellites can be used for producing maps of within-field crop and soil parameters and, consequentially, spatially variable rate crop input application maps. The plant vegetative vigour index (i.e., Normalised Difference Vegetation Index—NDVI) and the leaf water content index (i.e., Normalised Difference Water Index—NDWI) maps were used to study—through both time and space—the phenological phases of two plots, with Syrah and Nero d’Avola grapevine varieties, in a Sicilian vineyard farm, located in Naro (Agrigento, Sicily, Italy). The aim of this work is to produce spatially variable rate nitrogen fertiliser maps to be applied in the two vineyard plots under stu…
The Analysis of the Factors Influencing the Severity of Bicyclist Injury in Bicyclist-Vehicle Crashes
2021
Transportation and technological development have for centuries strongly influenced the shaping of urbanized areas. On one hand, it undoubtedly brings many benefits to their residents. However, also has a negative impact on urban areas and their surroundings. Many transportation and technological solutions lead, for example, to increased levels of pollution, noise, excessive energy use, as well as to traffic accidents in cities. So, it is important to safe urban development and sustainability in all city aspects as well as in the area of road transport safety. Due to the long-term policy of sustainable transport development, cycling is promoted, which contributes to the increase in the numb…
Knowledge Mapping of Optimal Taxation Studies: A Bibliometric Analysis and Network Visualization
2022
The problem of tax policy design has been an important concern over the years, involving comprehensive scientific research. In this study, our major goal was to examine and map the optimal taxation research thematic structure by using bibliometric analysis. The analysis was carried out with the CiteSpace software on publications indexed by Web of Science (WoS) between 1975 and 2021. This document offers an actual bibliometric analysis of the current research climate in terms of optimal taxation, based on the following aspects: (1) descriptive characteristics of publication outputs (distribution by years, authors, countries, journals); (2) collaboration analysis of authors, institutions, and…
