From banks' strategies to financial (in) stability
No full textThis paper aims to shed light on the emergence of systemic risk in credit systems. By developing an interbank market with heterogeneous financial institutions granting loans on different network structures, we investigate which market architecture is more resilient to liquidity shocks and how the risk spreads over the modeled system. In our model, credit linkages evolve endogenously via a fitness measure based on different banks' strategies. Each financial institution, in fact, applies a strategy based on a low interest rate, a high supply of liquidity or a combination of them. Interestingly, the choice of the strategy influences both the banks' performance and the network topology. In this way, we are able to identify the most effective tactics adapt to contain contagion and the corresponding network topology. Our analysis shows that, when financial institutions combine the two strategies, the interbank network does not condense and this generates the most efficient scenario in case of shocks

Public value creation experiences in hybrid organizations: a preliminary case study
No full textThis paper presents a preliminary case study investigating the public value creation experiences within the context of the "Sub-
Equana Valley" Smart Energy Community (SEC). The objective of this work is to explore the multifaceted nature of public
value and assess its creation in hybrid organizations operating in the SEC. A hybrid organization refers to a unique entity that
combines elements of both public and private sectors, seeking to achieve societal and economic goals simultaneously. To achieve this
objective, a mixed-methods research approach was employed, combining qualitative and quantitative data collection methods. The
study encompassed interviews with key stakeholders, including community members, government officials, and representatives from
the SEC's hybrid organizations. Additionally, surveys and document analysis were conducted to gather comprehensive data on the
SEC's public value creation processes. The results of this study reveal the diverse public value creation experiences within the Sub-
Equana Valley SEC. Three key public value mechanisms emerged from the analysis: collaboration and partnerships, innovative
technologies and community engagement and empowerment. Furthermore, the findings highlight the interplay between public and
private actors in the creation of public value, emphasizing the significance of hybrid organizations as vehicles for achieving
sustainable development goals. The originality of this contribution lies in its exploration of public value creation experiences within
hybrid organizations operating in the context of a Smart Energy Community. While prior research has investigated public value
and hybrid organizations separately, this study synthesizes these concepts, providing a holistic understanding of how hybrid
organizations contribute to public value in the SEC. By focusing on the Sub-Equana Valley case study, this research adds
empirical evidence to the growing body of literature on hybrid organizations and expands our understanding of their role in driving
societal progress. Overall, this preliminary case study sheds light on the complexity of public value creation within hybrid
organizations in the specific context of a Smart Energy Community. The findings have practical implications for policymakers,
community leaders, and practitioners involved in designing and managing hybrid organizations, providing insights into the factors
that contribute to successful public value creation. Further research is needed to explore additional case studies and refine our
understanding of the dynamics of public value creation within hybrid organizations in various contexts
Active Leakage Control with WDNetXL
No full textAbstractWater losses in Water Distribution Networks (WDNs) are classified in background and burst outflows. Bursts are generally the natural evolution of background leakages, driven by external factors that entail major water outflows, generating changes of WDN hydraulic functioning, detectable as anomalies in monitored flow/pressure data. Active leakage control strategies aim at prompt detection, localization and repair of pipe burst, thus reducing possible damages to private/public properties, minimize unplanned works, and reduce volume of lost water.This contribution presents the novel Leakage Control module of the WDNetXL system, aimed at supporting various active leakage control actions ranging from the design of effective pressure sampling system up to prioritizing of possible failed pipes to survey
Optimal Design of District Metering Areas
No full textAbstractThe search for optimal segmentations aimed at defining district metering areas (DMAs) is a challenging and crucial issue in the analysis, planning and management of water distribution networks (WDNs). The need to select optimal segmentations relates to a number of important technical reasons. Today, the most relevant one is the leakage management by means of pressure-control zones. This contribution proposes a novel two-steps strategy for DMAs planning. The strategy is based on the segmentation design as first step, to achieve a scenario of optimal locations of “conceptual cuts”; during the second step, these are the candidate for the location of (closed) gate valves or flow measurement devices that gave rise to district monitoring areas (DMAs). The segmentation step is performed solving a multi-objective optimization problem (i.e. WDN-oriented modularity maximization versus the number of “conceptual cuts” minimization).The second step accomplishes the real DMAs design by solving a three-objective optimization, i.e. the minimization of the background leakages versus the unsupplied customers demand versus the flow observations. This means that the procedure will search for a set of scenarios having a number of closed gate valves installed at the “conceptual cuts” that do not decrease the WDN hydraulic capacity below that necessary for a sufficient service to customers, while contemporarily reducing the background leakages. A pressure-driven modelling approach is used to predict background leakage reduction and the unsupplied customers demand. The procedure is explained on a benchmark network from literature, the Apulian network
An approach to identifying micro behavior: How banks’ strategies influence financial cycles
No full textIn this paper, we show that the values of parameters of a well-calibrated model are useful in detecting micro behavior. We use a calibration procedure suitable for validating agent-based models to show how the evolution of model parameters, obtained via a rolling window estimation, illustrates the evolution of agents’ strategies in response to different economic conditions. In this regard, we calibrate the well-known financial model of Brock and Hommes using three banking indices (i.e., the S&P SmallCap 600 Financials Index, the STOXX Europe 600 Banks, and the STOXX Asia/Pacific 600 Banks) running from 1994 to 2016. The choice of a spatially and temporally diversified dataset allows us to analyze differences and similarities in the behavior of banks belonging to the different macro areas, as well as to capture agents’ reaction to the several economic phases characterizing the time series investigated
Optimal pump scheduling strategies accounting for background leakages and energy cost
No full textPumping optimization in water distribution networks means to schedule the ON/OFF status of pumps over a typical operating cycle, pursuing the minimum energy cost for pumping and matching technical requirements, e.g. sufficient pressure to satisfy customers water requests, null water deficit at tanks, avoid complete emptying and overflows of tanks. In aged water distribution networks, pump scheduling should also minimize pressure-dependent leakages, entailing loss of water and energy, as well as asset deterioration. Although pumps are usually scheduled over time, controlling pump status by water level in tanks provides a more robust strategy in face of uncertain water demands. This work demonstrates that advanced hydraulic modelling, enabling the simulation of pressure-dependent background leakages and variable level tanks, allows optimizing levels in tanks that control pumps reducing energy costs for pumping and leakages, in a complex water distribution network
A comparative study of form and theology in the works of Flannery O'Connor and Simone Weil
No full textIn this comparative study of the form and theology of Flannery O'Connor and Simone Weil I interrogate how Weil's philosophical writings and her theology illuminate O'Connor's use of both narrative and non-fictional forms, and her Catholicism. The Introduction analyses how Weil's concept of superposed reading provides a new method of approaching both O'Connor, her writings, and O'Connor
studies, and focuses on how such apparently different women interconnect. Chapter One explores how both Weil and O'Connor attempt to write their theologies on the
souls of their readers yet are each subject to constraints imposed by form. Weil's concept of locating equilibrium between incommensurates is discussed, and her
distinctively philosophical approach to fictions and fictionality is used to investigate O'Connor's notion of prophetic fictions and the writer's role. Chapter Two assesses how both writers revivify Christian paradoxes. Weil's monstrous concept of affiiction, and O'Connor's use of the grotesque genre to jolt secular man into an
awareness of the sacred are scrutinised. Chapter Three studies how both writers consider an encounter between God and man is possible through the action of grace. My Conclusion interrogates how Weil's work can deepen our understanding of O'Connor's writings, and examines how successful O'Connor is at realising a truly
Christian literature. I conclude that despite being a writer of powerful fictions, O'Connor can not be totally successful in her mission as writer-prophet because
ultimately fiction escapes orthodoxy
