High-commitment work practices and the social responsibility issue: interaction and benefits
2021
Human Resource Management (HRM) has a potentially vital role to play in addressing the new challenges that companies have to face and in delivering initiatives in the framework of corporate sustainability. Our work attempts to shed light on the strategic role of High-Commitment Work Practices (HCWP) as a Corporate Sustainability (CS) partner and, more specifically, to analyze the implications of their integration on the competitiveness of the firm. With this purpose, we apply a qualitative methodology, using a single case study, to explore and explain why and how the interaction between HCWP and CS takes place. The results show how this interaction encourages the formulation and implementat…
Energy Retrofit. A Case Study—Santi Romano Dormitory on the Palermo University
2021
Electrical and thermal consumption related to buildings, whether civil, commercial, public, or of any other kind, is very much in focus today. With today’s targets for energy savings, reduction of consumption, and environmental impact, it is necessary to carry out energy retrofits to modernize installations and their management. The realization of an effective improvement requires a careful analysis of the case study because each category of building has different requirements such as different load profiles and different installations and needs. This was carried out by studying the electrical and thermal load profiles. A good initial energy audit can provide the retrofit solutions capable …
Analysing the Impact of the Glass Ceiling in a Managerial Career: The Case of Spain
2021
The need to break down the barriers facing women in the labour market arouses great interest for reasons of social and sustainability justice. This study breaks new ground on the topic of the “glass ceiling” by assessing the evolution of gender inequality in the proportion of individuals reaching high managerial positions. The application of the csQCA method to a survey of two cohorts of Spanish graduates in management sharing the same starting conditions reveals two factors: job variety and additional education, as conditions that are usually present in a successful managerial career. Our findings confirm the prevalence of the gender gap with little progress in recent years. Women find it …
Home Country Institutions and Outward FDI: An Exploratory Analysis in Emerging Economies
2020
Although the internationalization of economies is driven by specific industry conditions or business-specific differences, the institutions that exist as background conditions directly determine firms&rsquo
Remote Sensing Observations of Thunderstorm Features in Latvia
2017
AbstractThunderstorms are the most hazardous meteorological phenomena in Latvia in the summer season, and the assessment of their characteristics is essential for the development of an effective national climate and weather prediction service. However, the complex nature of convective processes sets specific limitations to their observation, analysis and forecasting. Therefore, the aim of this study is to analyse thunderstorm features associated with severe thunderstorms observed in weather radar and satellite data in Latvia over the period 2006–2015. The obtained results confirm the applicability of the selected thunderstorm features for thunderstorm nowcasting and analysis in Latvia. The …
Paving the way for the Paris Agreement:Contributions of SDEWES science
2023
Today, coal is responsible for 40% of annual CO2 emissions. At the same time, global warming causes climate changes accompanied with catastrophic meteorological phenomena all over the world. After the 2015 Paris Agriment many countries set ambitious energy policy to reduce the annual greenhouse gas emission. The 2021 UN Climate Change Conference, COP26 - Glasgow, ended with the adoption of a less stringent resolution than some anticipated: countries only agreed to “phase down” rather than “phase out” coal. Is possible the realization of the Paris Agreement after COP-26? For achieving this ambitious targets in such conditions, the support of the multi-disciplinary scientific knowledge is nee…
Recent advances in methods, policies and technologies at sustainable energy systems development
2022
Following the 2015 Paris Agreement and other agreements which have been signed after, sustainable energy development is becoming the major goal in many countries. EU have set the targets to reduce the annual greenhouse gas emission by 40% in 2030 and 80% for 2050 compared with 1990 levels. For achieving this ambitious energy policy, three major technological changes are available: energy savings on the demand side, efficiency improvements in the energy production, and replacement of fossil fuels by various sources of renewable energy. Also, for realization cited three major technological changes the support of the multi-disciplinary scientific knowledge is needed. Therefore, from the beginn…
Graded Carrier Concentration Absorber Profile for High Efficiency CIGS Solar Cells
2015
We demonstrate an innovative CIGS-based solar cells model with a graded doping concentration absorber profile, capable of achieving high efficiency values. In detail, we start with an in-depth discussion concerning the parametrical study of conventional CIGS solar cells structures. We have used the wxAMPS software in order to numerically simulate cell electrical behaviour. By means of simulations, we have studied the variation of relevant physical and chemical parameters-characteristic of such devices-with changing energy gap and doping density of the absorber layer. Our results show that, in uniform CIGS cell, the efficiency, the open circuit voltage, and short circuit current heavily depe…
