Estrategias de adaptación del texto calderoniano en La vita è un sogno atribuida a Giacinto Andrea Cicognini
No full textThis study examines some characteristics of the Italian adaptation of La vida es sueño (La vita è un sogno, 1662-1663) attributed to Giacinto Andrea Cicognini, placing particular emphasis on four aspects: Segismundo's transgressive and rebellious attitude and his passionate disposition are notably toned down; at the same time, Basilio's negative traits are softened or eliminated; moments and situations of moral edification are intensified or created ex novo; and finally, the stage presence of Astolfo and Estrella, and their relationship with Rosaura, is strikingly expanded, to the detriment of the relationship between Rosaura and Segismundo
Newborn Infants Selectively Attend to Points That Refer to Objects
No full text: Recognizing that certain acts are communicative is a key requirement of the development of communicative skills. Newborn infants have been shown to selectively respond to certain ostensive cues, including mutual gaze and infant directed speech, supporting theories of the evolution of ostensive-inferential communication. That said, no study has yet examined newborns' responses to pointing gestures, nor whether these responses are sensitive to pointing as an ostensive cue. The current study investigates whether a sensitivity to pointing is present in 5-day-old newborns by comparing newborns' attention to a pointing hand versus a fist via a preferential looking paradigm. Across 4 Experiments with 5 conditions (N = 90), we manipulated several key factors in the communicative nature of pointing: (a) the presence versus absence of a referred-to target (Experiment 1), (b) whether the pointing entity was social versus non-social (Experiment 3), and (c) whether or not the point referred to a target by moving toward versus away from it (Experiment 4). Newborns in Experiment 1 looked longer at a pointing human hand than a non-pointing fist, but only in the presence of a target object; attention to a target-directed point was replicated in Experiment 2. In contrast, newborns in Experiments 3 and 4 showed no visual preference for an arrow over a disc when each moved toward a target, nor for a point over a fist when each moved away from a target. Together, these results are the first to suggest that newborn infants are sensitive to a key communicative gesture, pointing, and that their responses are specific to points that are both social (i.e., human hands) and communicative (i.e., referential). These findings support the existence of an experience-independent sensitivity to pointing as an ostensive signal, consistent with theories of the evolution of ostensive-inferential communication
Big Data and Innovation: The State of the Art and Future Research Directions
No full textCompanies are increasingly aware of the benefits that can come from using big data. Of the various ways firms can make use of big data, in our research we have focused specifically on its use for innovation. As there are still many aspects that need to be clarified in this respect, our study addresses the following research question: how can big data be leveraged for innovation? Through a systematic literature review, we have inductively shown that three aspects emerge as critical in dealing with big data and innovation: (i) big data conceptualization; (ii) big data outcomes; and (iii) contingency factors. Around these aspects, we have mapped the current state of the art on big data and innovation, as well as highlighting interesting future research directions. On the whole, we have sought to advance scientific knowledge and provide useful insights for managers and research centers regarding the best way to leverage big data and innovation

No full textOnline Active Impedance Estimation Method in an LCL-Grid-Tied VSI: Analysis of the Multi-Sine Perturbation
No full textAccurate grid impedance estimation is essential for the stability and efficiency of modern power systems, especially with high renewable energy penetration. This paper introduces a signal-based on sum of sine waves (Multi-Sine) approach for broadband impedance estimation, offering superior spectral efficiency and adaptability compared to traditional methods like Pseudo Random Binary Sequence (PRBS) and White Noise. The proposed method ensures precise characterization while minimizing grid disturbances. Validated experimentally on a 60 kW VSI connected to an emulated grid, the approach demonstrates reliable performance under varying conditions, including weak grids and dynamic loads. These findings highlight the practical applicability of Multi-Sine signals, advancing grid management and stability in renewable-dominated systems
