Inferring human preferences in multisector systems via Inverse Reinforcement Learning
No full textIn a changing climate and society, the importance of cross-sector interactions becomes crucial for understanding the co-evolution of human and natural systems, where the role of individual and collective human decisions is a major driver of system vulnerabilities and adaptive capacity. While mathematical models of natural processes have been studied and developed for centuries and, today, they are extremely sophisticated at fine spatial and temporal scales, there is an urgent need to shed light on the key role of human behaviors across multisector systems. For instance, the majority of current global hydrological models incorporate pre-defined rules for simulating reservoir operations, which distinguish between reservoirs used for irrigation or non-irrigation purposes only. However, many water systems are operated to meet competing multi-sector demands and it is often unclear how operators confront these demands.
In this work, we introduce a Reinforcement Learning approach to model the dynamics of multipurpose reservoir systems. Specifically, our method first uses Inverse Reinforcement Learning to identify the trade-off among competing objectives from historical observations of the reservoir system dynamics. The identified objective function is then used in the formulation of an optimal control problem returning a closed-loop policy which allows the simulation of the observed dynamics of the reservoir system. We demonstrate the potential of the proposed method in a real-world application involving the multipurpose regulation of Lake Como in northern Italy. Results show that our approach effectively infers the trade-off between flood control and water supply adopted in the observed system’s operation, and yields a control policy that closely approximates the observed system dynamics

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
The Italian Parliament: In search of a New Role?
No full textThe so called “Italian transition” of the 1990s has a profound impact on Parliament, albeit often of a quite unexpected kind. Many external changes forced it to modify its role and performance, but as usually happens when a well-established institution is under strain, Parliament tried to resist by adapting in order to maintain its specific, historically-rooted patterns of behaviour and internal principles. The chief prize at stake has been Parliament’s central institutionalised role within the political system, and its formal and substantial prerogatives in the legislative process. The political trend urged the parliamentary institution to adjust to the much-invoked bi-polar dynamics, which basically meant the acceptance of the centrality of Government in the legislative process. At the same time, it was encouraged to change the content and the quality of its functions, by focusing more – as Bagehot would have it - on its expressive, oversight and electoral activities rather than on its legislative functions. Parliament was thus asked to radically change its institutional identity, its deeply consolidated internal practices dating back to the age of liberalism. Above all, traditional patterns of behaviour (culturally reproduced within assemblies), challenged by external changes, included: the absence of a clear majority/opposition divide; the lack of any strong institutional tools favouring the prominence of Government within Parliament; the consensual decisional style.
Did Parliament respond positively to those demands? The data and facts we have presented in this article point to a rather contradictory, ambiguous situation
