Dai batteri a Bach di Daniel C. Dennett
No full textFausto Caruana, Carmela Morabito and Simone Pollo discuss Daniel Dennett’s From Bacteria to Bach and Back. The authors critically survey the book and discuss some of its key topics from different theoretical viewpoints. Caruana analyzes Dennett’s reconstruction of the evolution of mind moving some critical suggestions derived from the pragmatist tradition in philosophy of mind. Morabito discusses some couples of opposing concepts used by Dennett and discusses his conclusion about the alternative between bottom-up and top-down processes in the evolution of mind. Pollo equally tackles Dennett’s opposition between bottom-up and top-down processes as it is presented in Dennett’s account of the evolution human culture and the presumed withdrawal of human civilization from Darwinian processes
Advances in neural networks computational and theoretical issues
No full textThis book collects research works that exploit neural networks and machine learning techniques from a multidisciplinary perspective. Subjects covered include theoretical, methodological and computational topics which are grouped together into chapters devoted to the discussion of novelties and innovations related to the field of Artificial Neural Networks as well as the use of neural networks for applications, pattern recognition, signal processing, and special topics such as the detection and recognition of multimodal emotional expressions and daily cognitive functions, and bio-inspired memristor-based networks. Providing insights into the latest research interest from a pool of international experts coming from different research fields, the volume becomes valuable to all those with any interest in a holistic approach to implement believable, autonomous, adaptive, and context-aware Information Communication Technologies
Sulle tracce di un motivo patristico nella letteratura slava ecclesiastica serba
No full textA Pratistic Motif in Serbian Church Slavic Literature
In manuscript 159 MSPC the author verifies the presence of the same text that preceded Slovo ljubve in ms 29 of Narodna Biblioteka Srbije, lost during the bombardments of 1941. The motif of a fishermen enlightened by God that dates back to Emphrem Syrus’ Parenaesis appears in it. The author follows this motif in its tracks in older Serbian Church Slavonic literature (in the lives of St. Simeun and St. Sava by Domentijan), in Slavic and Byzantine liturgy, and in patristic literature (John Chrysostom) and hymnography (Roman the Melodist)
The birth of clinical psychology in the scientific work of Lightner Witmer [La nascita della psicologia clinica nell'opera di Lightner Witmer sui bambini con ritardo mentale.]
No full textThe paper deals with the beginning of Clinical Psychology in the first years of XX century, when a central role was played by the theoretical and practical approach on mental retardation and behavioural disorders of L. Witmer. The author describes the cultural formation of Witmer, between Structural Psychology and Functionalism, and the special attention he devoted to the management and education of children affected by mental retardation and behavioural problems. ... Any child, the functions of whose brain are not developed up to the normal limit for his age, is suffering from retardation ... Retardation must be defined in terms of individual capacity for physical and mental development...
Analogic realization of a non-linear network with re-configurable structure as paradigm for real time analysis of complex dynamics
No full textA novel experimental set-up realized for the real time analysis of reconfigurable complex networks, with chaotic Chua’s circuits as nodes, is considered. It has been designed to easily perform large scale experiments on networks of chaotic oscillators, possibly exploring in real time the parameters space in terms of topologies, coupling strengths, nodes’ dynamics, with potential application in the area of neuro-computing and associative dynamic memories. A sample of the capabilities is given by considering diffusive coupling with a large range of coupling strengths in a set of topologies, and first experiments on a ring of 32 chaotic nodes are reported. Synchronization, chaotic waves and patterns are experimentally observed, and the potential of the realized set-up in terms of accuracy, flexibility and analysis time is fully revealed
A new alternative technique for sterilising invasive crayfish: removing female pleopods did not alter courtship pheromone release in signal crayfish
No full textInvasive species require effective management, especially when population density is still low. Autocidal methods for controlling invasive species offer the advantages of being species-specific and inversely density dependent, without causing environmental changes. An ideal control technique should decrease numbers of juveniles, and, therefore, progressive population ageing. In crayfish, female pleopods can be removed to eliminate support for the attachment of newly fertilised eggs. The aim of this study was to investigate if pleopod removal affects the release of female sexual pheromones. An experiment was performed by exposing signal crayfish males to four waters conditioned by (1) mature females after cutting pleopods (treated), (2) untreated mature females, (3) sexually inactive females, and (4) control water. Males exposed to both treated and untreated mature female waters showed behavioural similarities and increased mating activity compared to males exposed to sexually inactive female or control waters. Removing female pleopods did not affect the release of courtship pheromones, so treated females were still able to attract males by misleading them into mating activity. When females spawn their eggs, they will be lost due to the missing pleopods. Therefore, this method might be considered to control invasive crayfish in management programmes
Testing the weak form market efficiency: empirical evidence from the Italian stock exchange
No full textThis paper investigates the use of feed forward neural networks for testing the weak form market efficiency. In contrast to approaches that compare out-of-sample predictions of non-linear models to those generated by the random walk model, we directly focus on testing for unpredictability by considering the null hypothesis that a given set of past lags has no effect on current returns. To avoid the data-snooping problem the testing procedure is based on the StepM approach in order to control the familiwise error rate. The procedure is used to test for predictive power in FTSE-MIB index of the italian stock market
