Supplying small islands with solar, wind and sea wave. An economic approach to find the best energy share
2019
The progressive installation of power plants based on renewable energy sources is improving the sustainability of the energy sector. Despite the availability of commercial solutions, most of the small islands in the world are nowadays affected by a deep dependence on fossil fuels. In this context, the paper investigates the feasibility of an energy mix composed by solar, wind and sea wave, suggesting a sizing approach based on the minimization of the Levelized Cost of Electricity of the entire energy mix. As case study, the Aeolian Islands are presented.
Assessing environmental performance in the European Union: Eco-innovation versus catching-up
2017
Abstract This paper assesses environmental performance in the European Union (EU) using Luenberger productivity indicators, directional distance functions and Data Envelopment Analysis techniques. It considers four indicators of the pressures exerted by economic activity on the environment: global warming, tropospheric ozone formation, acidification and particulate formation. The change in environmental performance from the early 2000s onwards is decomposed at the levels of country and environmental pressure, and as the result of eco-innovations and catching-up with the best available environmental technologies; furthermore, we distinguish between the periods of economic growth (2001–07) an…
Perspectives and challenges of small scale plant microalgae cultivation. Evidences from Southern Italy
2020
Abstract In recent years, the cultivation of algae has achieved attention of scientists and practicioniers due to the great variety of products that can be obtained, among which biofuels. The aim of this work is twofold. The first is to perform a profitability analysis of food and biofuel production from microalgae, in a small-scale setting. The second is to assess the economic impact of algae production systems on the dairy farms potentially interested in Southern Italy. The analysis was performed using financial and economic indicators and considering two system management scenarios, namely single and collective. Our results confirm that current microalgae production technology favors bio…
Bioenergy Production and Social Sustainability on Finnish Farms
2011
Problems related to energy production have become a significant social issue, also regarding rural areas. There is an apparent need to establish a model for sustainable energy production that would encompass economic, environmental and social sustainability (Elliott 2000). One important solution to reducing carbon dioxide emissions, as well as addressing the depletion of fossil fuel resources, lies in the renewable natural resources that exist in rural areas. However, sustainable and reasonable utilization of these resources is not simple and requires specific analysis of different production models (Mol 2007). Simultaneously, one must consider how these rural resources can be utilized and …
Green energy products in the United Kingdom, Germany and Finland
2014
In liberalized electricity markets, suppliers are offering several kinds of voluntary green electricity products marketed as environmentally friendly. This paper focuses on the development of these voluntary markets at household level in the UK, Germany and Finland. Since there are already existing renewable energy policies regulating and encouraging the use of renewable energy, it is important to consider whether voluntary products offer real additional benefits above these policies. Problems such as double counting or re-marketing hydropower produced in existing plants are identified. According to our study, the demand varies between countries: in Germany the number of green electricity c…
Human resource practices and employee wellbeing from a gender perspective: The role of organizational justice
2021
Introduction/objective: HR practices have been widely studied in the literature. However, critical research gaps remain unexplored. Little attention has been paid to the relationship between HR practices and well-being, or the mechanisms that explain the effect of HR on employees’ wellbeing, and the role of gender in this relationship. Hence, this study aims to examine the relationship between HR practices and well-being (eudemonic and hedonic) through organizational justice, taking into account gender. Method: A convenience sampling technique was used in a correlational design. The sample was composed of 1647 employees from 42 Spanish organizations. Our measures were HR practices, organiza…

This study explored relationships between organizational assimilation, organizational reputation, and organizational dissent. Survey data collection using standard instruments was conducted with a ...
Complying With the First Law of Robotics: An Analysis of the Occupational Risks Associated With Work Directed by an Algorithm/Artificial Intelligence
2020
It is increasingly common for companies to use artificial intelligence mechanisms, which may be more or less advanced, to manage work, that is, to establish work shifts and production times, design and allocate tasks for workers, recruit workers, evaluate performance and dismiss employees. Companies rely on technology to gather all the information available, process it and make the management decisions (productivity optimisation) that will benefit them the most. This replaces human supervisors and middle managers, as well as experts in human resources, leaving the management of workers in the hands of automated processes directed by algorithms – or in its most advanced stage, to be undertak…
Kerr Combs and Telecommunications Components for the Generation and High-Dimensional Quantum Processing of d-Level Cluster States
2019
Large and complex optical quantum states are a key resource for fundamental science and applications such as quantum communications, information processing, and metrology. In this context, cluster states are a particularly important class because they enable the realization of universal quantum computers by means of the so-called ‘one-way’ scheme, where processing operations are performed through measurements on the state. While two-level (i.e. qubit) cluster states have been realized thus far, further boosting this computational resource by increasing the number of particles comes at the price of significantly reduced coherence time and detection rates, as well as increased sensitivity to …
Life Cycle Assessment of Electricity Generation Scenarios in Italy
2018
Hindering global warming and achieving a more competitive, secure and sustainable energy sector are some of the most relevant goals of the 2030 Framework for climate and energy of the European Union. European countries have to identify and implement strategies for contributing to these ambitious goals. In this context, the authors carried out a scenario analysis on the Sicilian electricity mix in order to estimate the life cycle energy and environmental benefits of the increase of the use of renewable energy technologies for electricity production, and the potential contribution of Sicily in the achievement of the European energy and environmental targets. In detail, the authors identified …
