    FrameSAI: a Three-Layer Framework to Create Symbiotic AI Systems

    No full text
    As Artificial Intelligence (AI) becomes increasingly widespread in numerous domains of everyday life, humans must maintain their agency, valuing their expertise and judgment and preserving their privacy and safety. The research presented in this article aims at laying the groundwork for a standardized approach for creating systems, that allow a symbiotic relationship between the human and the machine. Specifically, we present a framework, called FRAMework to creatE SAI (FrameSAI), which guides practitioners in developing high-quality SAI systems while complying with law. It is composed of three layers (i.e., Principles, Guidelines, and Success Criteria), which become increasingly operational indications as one moves from one level to the next. A preliminary version of FrameSAI is presented, illustrating a first set of guidelines and success criteria mapped to the four levels of risks of the AI Act, the European Union (EU)’s regulation for the design, development, and deployment of AI system

    How can urban exploration function as a site of learning? What epistemological frameworks can drive innovation in teacher education? As part of the EU Green Week, the W.E.R.S.Um. project engaged 100 undergraduate students in Primary Education Studies in a critical re-examination of the city as an educational milieu. Drawing on Keri Smith’s publications, participants systematically observed and documented the urban fabric, adopting a phenomenological stance to inhabit space intentionally and to cultivate an embodied understanding of the concept of citizenship. The analytical process, grounded in the examination of exploration journals and experiential data collection workshops, underscored the extent to which this methodological approach fostered critical reflexivity among future educators. This engagement facilitated the development of pedagogical tools for a transformative and inclusive educational practice, one deeply embedded in local contexts and conducive to the promotion of active citizenship within schools

    Sustainability, Business Risk and ESG Rating - Empirical Evidence from the European Stock Markets

    No full text
    Corporate social strategies develop socially responsible actions with the goal of improving business performance and creating value for all stakeholders. These days, environmental, social, and governance (ESG) objectives play a crucial role within companies, which are faced with the imperative to pursue social, environmental, and financial performance at the same time, leading to improved corporate sustainability. It is now evident that ESG issues have an influence not only on profitability but also on the financial strength of various companies. Beginning in 2004 with the publication of the Who Cares Wins report by the United Nations Global Compact Initiative (UN, 2004), the importance of grouping three of the main pillars of ethical finance together has emerged, namely ESG. The environmental pillar assesses a company's efforts in terms of energy efficiency, greenhouse gas emissions, waste, water, and resource management. The social pillar refers to aspects related to gender policies, human rights protection, labour standards, workplace and product safety, public health, and income distribution, which affect employee satisfaction. Finally, the governance pillar covers aspects related to board independence, shareholder rights, manager compensation, control procedures and anti- competitive practices, and compliance with the law. It is an approach that follows a multidimensional logic with a view to improving quality of life expectations, innovation, and business competitiveness without neglecting the well-being of all human generations. Entrepreneurs, investors, and people in general have begun to become aware of this and be more sensitive in making decisions. More and more sustainable companies are striving to improve their ESG investments, and there is now a growing trend for investors to invest in socially responsible and sustainable companies. The concept of ESG performance is intended to provide an assessment of the degree to which a company manages ESG risks and opportunities (MSCI 2018). ESG scores make companies comparable in terms of actual risk factors that impact the cost of capital. In recent years, many studies have analysed the relationship between the ESG profiles of companies and their financial risk and performance characteristics by distinguishing, with respect to risk, between systematic and idiosyncratic stock risk. Systematic risk is macroeconomic in nature and describes the general market risk to which all companies are exposed, such as the risk of shocks in commodity prices, interest rates, or inflation rates. Systematic risk also includes industry-wide issues, such as regulatory changes and technological developments. Firm-specific risk, on the other hand, is specific to a firm. The distinction between systematic and firm-specific risk is important in analysing the impact of ESG characteristics on firm valuation because investors can typically diversify away from firm-specific risk; therefore, it is only the systematic risk component that determines the rate of return required by shareholders to offset the risk they are exposed to. Companies with sound ESG practices exhibit lower cost of capital, lower volatility, and fewer cases of corruption and corporate fraud (Bank of Italy, 2019). In this regard, several empirical studies highlight that "good practices" from an ESG perspective allow companies to benefit from competitive advantages, lower cost of capital, and better operational and market performance. The academic literature is unanimous in supporting the positive effect that ESG factors have on decreasing the cost of capital, pointing out that the main reasons for this contraction can be attributed to the reduction of information asymmetry. Sharfman and Fernando (2008), analysing a sample of 267 U.S. companies, have tested whether better environmental risk management is rewarded by financial markets in terms of lowering the cost of capital. In relation to the cost of capital, the results suggest a negative association between the latter and environmental risk management, due to the lower beta, an expression of the volatility of the company's stock. These results are confirmed by subsequent studies showing the negative association between sustainable business practices and the cost of capital, such that an increase in socially responsible actions implies a decrease in the cost of capital. Studies that, on the other hand, analyse sustainable financial and non-financial performance (again in relation to the cost of capital) have shown that each sustainable approach has an impact on the cost of capital, confirming the results of previous studies (El Ghoul et al., 2011; Matthiesen and Salzmann 2017; Cuadrado-Ballesteros et al., 2016). Nonetheless, the integration of critical perspectives within ESG finance literature is essential for advancing scholarly rigour and fostering a more nuanced understanding of the field, one better capable of fully realizing the hoped for "investor revolution" (Eccles and Klimenko, 2019) in the transition to a more sustainable economy. Existing critiques—such as portraying ESG practices as "ethical window dressing" (Muñoz et al., 2022) or highlighting the limitations of over-reliance on rating metrics (Berg et al., 2022)—serve a vital role in scrutinizing the efficacy and authenticity of ESG commitments. Incorporating these critical viewpoints can mitigate potential biases and promote a more balanced discourse, thereby enhancing the credibility and robustness of academic research. Studies that systematically address these critiques could provide deeper insights into the normative and practical implications of ESG integration, ultimately contributing to more rigorous and comprehensive scholarship in the field of sustainable finance (UNEP-FI, 2018). This study, considering these theoretical premises, investigates whether the relationship between ESG merit and systematic risk has changed because of specific events that have steered the economy and financial markets towards an increased focus on ESG aspects, including the establishment of the 2030 Agenda for Sustainable Development on September 25, 2015, and the subsequent stipulation of the Paris Agreement on December 12 of the same year. The analysis is carried out using a methodological framework based, in line with previous literature, on econometric techniques traceable to the Capital Asset Pricing Model model declined by Sharpe in 1964 and the five-factor model developed by Fama and French in 2015. The analysis sample consists of 596 of the 600 companies included in the STOXX Europe 600 stock index in 2023, whose ESG scores are provided by Refinitiv. The market indices considered in the analysis are represented by both the MSCI world and the STOXX Europe 600 itself. For the purposes of the above verification, the sample is divided into quartiles based on the distribution of the relevant scores to verify any different impact on systematic risk after the specific event identified as being relevant to the path towards a more sustainability-based economy. The analysis focuses attention on both the overall ESG score and the three pillars (E, S, and G) considered individually. The empirical evidence obtained shows a reduction in systematic risk, following the stipulation of Agenda 2030 in September 2015, of greater significance in terms of both the size of the impacts and the statistical significance associated with them for equity indices constructed considering companies with higher ESG merit. The evidence provides interesting new functional elements for the study of the relationship between ESG merit and systematic risk, providing useful implications for decisions not only by policymakers but also by regulators regarding the integration of ESG factors into the risk measurement, monitoring, and management procedures of financial and non- financial firms. The study is structured as follows. The first chapter aims to provide a sufficiently comprehensive overview of the concept of sustainability and the strategic contribution made by businesses to the community, even with respect to the different legislative interventions aimed at focusing the attention of individuals and legal entities on sustainability and achievement of the 17 Sustainable Development Goals (SDGs) signed by 193 states and outlined in the 2030 Agenda. The second chapter delves into the concept of corporate risk through a review of prevailing national and international literature on the subject, from which it emerges that any organization, regardless of its size or sector, is called upon to manage its risks, whether they are related to economic aspects, ESG aspects, or both, ensuring that they are kept within acceptable levels over time. Risk management, and in particular the emerging ESG risks, has become a must-have practice to be applied by following a systematic and organized approach, with constant recourse to discipline-specific methodologies and techniques, including the provision of an effective Enterprise Risk Management Framework, which is a fundamental cornerstone of a good governance system. The third chapter initially looks at the recent development of ESG rating agencies and, consequently, ESG ratings. These are scores that encompass not only the quality of corporate governance systems but also environmental, social and, more generally, sustainability issues. After highlighting the main peculiarities of but also critical issues in such sustainability indicators, the chapter focuses on the relationship between ESG factors, systematic risk, and performance. About the first relationship, i.e. between ESG ratings and systematic risk, the literature agrees that firms with higher ESG ratings have lower systematic risk (a lower beta) and, consequently, a lower cost of equity than firms with lower ESG ratings. Regarding the relationship between ESG factors and performance, the literature shows mixed results. According to some studies, companies with high ESG ratings have higher returns especially during recessionary periods, thus showing themselves to be more resilient. However, in some circumstances, it has been found that non-proprietary managers often use the funds allocated for carrying out socially responsible activities for purely personal purposes. Such an attitude, in the long run, could undermine profitability and, therefore, business continuity. The fourth and final chapter, following the outlining of the research objectives, provides a description of the sample under investigation and the methodology used. In the last part of the chapter, the econometric model is presented, and then the results obtained from the analysis are discussed

    Characterizing flow regime and its alterations in an intermittent river: the Canale d’Aiedda case study

    No full text
    Anthropogenic activities, such as waste water treatment plants dis- charges (WWTPs), impact the natural river regime. The assessment of the “im- pacted” and “un-impacted” hydrological conditions is of paramount importance for the river management. Methodologies for characterizing flow regime and its alterations are based on streamflow data recorded over a long period. Data re- quirements may be a limitation in regions where the recorded data are not avail- able or poor (i.e. short time series, presence of gaps). Hydrological models, such as the Soil and Water Assessment Tool (SWAT), may be used to generate long-term time series of daily or monthly streamflow. In this work, an approach to characterize the flow regime of an intermittent riv- er and to assess its alterations using the SWAT model is defined. The aims are: (i) adapt SWAT for simulating daily streamflow in the Canale d’Aiedda river (Italy), (ii) characterize its flow regime, and (iii) assess the hydrological regime alterations due to WWTPs. The flow regime was characterized by using several hydrological indicators, based on the long-term time series of modeled daily streamflow. Hydrological regime classification of the river reaches receiving wastewaters from WWTPs shifted from intermittent to perennial. The components of the low flow (1-, 3-, 7-, 30-, and 90-day minimum flow, zero-days) and the monthly flow recorded in summer were severely altered. The concept of “zero-flow threshold”, defined on field observations was introduced to improve the model results. This study provides a contribution to the significant topic of the management of intermit- tent rivers under the Mediterranean climate

    Financial Challenges and Threats of Circular Economy Logistics

    No full text
    This chapter explores the economic aspects related to circular economy logistics and highlights the key financial challenges and threats that organizations may face when transitioning to a circular economy business model. We developeda methodological approach for researching financial challenges and threats, which consisted of 4 steps. In the 1st stage of the research, we identified the leader in the trade of processed raw materials—Germany and characterized the factors why this country is the leader. In the next stage, the authors reasonably identified possible financial threats that prevent the effective development of circular economy logistics. In the third stage, the relationship between the rate of reuse of materials and the exchange rate, interest rates, and inflation rates was investigated using the multiple regression method. Then, based on the results obtained in the first stage, we investigated which companies carry out their activities in the field of circular economy logistics. The hypothesis of the chapter is that the transition to circular economy logistics presents several financial problems and threats that must be carefully considered and resolved. By recognizing these challenges and adopting appropriate strategies, organizations can navigate financial challenges and unlock the economic benefits associated with the circular economy, promoting sustainability and resource efficiency

    A Review of the Key Findings from the Special Issue on “Life Cycle Sustainability Analysis of Resource Recovery from Waste Management Systems in the Context of Circular Models of the Economy and the Bioeconomy”

    No full text
    This special issue (SI) arises with the aim of addressing further the concern that sustainable waste management from the perspective of the Circular Economy (CE) can contribute towards a just and sustainable post-fossil carbon society. The time has come for CE-based societies in which responsible and sustainable ways of dealing with waste will be implemented and pursued. A successful transition will require the planning, design, testing and implementation of waste-based products that meet the three dimensions of sustainability or the 17 UN Sustainable Development Objectives. The SI further contributed to the awareness that waste can be valorised as a zero-burden resource and sustainably transformed into value-added material and energy commodities. It has also allowed to understand that CE principles can be applied to a wide range of sectors and issues, and that there are several scientifically based methodologies, such as LCA and related others. These methodologies were confirmed by this SI’s articles to be quite effective in scientifically assessing the impacts of CE measures on the systems to which they are applied. Finally, the SI confirmed the importance of academic research for assessing and stimulating the integrated sustainability of waste recovery systems from a CE point of view. In this way, the SI could serve as a platform for the advancement of knowledge on new methodologies, practical applications, state-of-the-art analysis, findings and lessons learned in such an important and up-to-date research field

    Empowering Mathematics Educators: Integrating ChatGPT as a Tool for Innovative Teaching Practices

    No full text
    This study investigates the potential of a customized ChatGPT model as a tool for enhancing mathematics teaching, specifically focusing on the concept of continuity for real-valued functions. Using the Knowledge for Teaching Mathematics with Technology (KTMT) framework as a theoretical basis, the research examines how personalized AI tools can improve task design, balance among mathematical representations, and the interplay between experimentation and justification. The experimentation involved in-service mathematics teachers who explored both a default and a customized ChatGPT model to create instructional resources. Qualitative analysis revealed that the customized model significantly improved the quality of resources, enabling the creation of diverse, representation-rich, and conceptually balanced tasks. Teachers reported that the personalized ChatGPT facilitated transitions between algebraic, graphical, and tabular representations, supported exploratory problem-solving, and provided opportunities for rigorous justification. The findings contribute to a deeper understanding of how AI-driven tools, when aligned with structured pedagogical frameworks, can support mathematics instruction and teacher development
