An analysis of the bias of variation operators of estimation of distribution programming
2018
Estimation of distribution programming (EDP) replaces standard GP variation operators with sampling from a learned probability model. To ensure a minimum amount of variation in a population, EDP adds random noise to the probabilities of random variables. This paper studies the bias of EDP's variation operator by performing random walks. The results indicate that the complexity of the EDP model is high since the model is overfitting the parent solutions when no additional noise is being used. Adding only a low amount of noise leads to a strong bias towards small trees. The bias gets stronger with an increased amount of noise. Our findings do not support the hypothesis that sampling drift is …
Estimates for the Differences of Certain Positive Linear Operators
2020
The present paper deals with estimates for differences of certain positive linear operators defined on bounded or unbounded intervals. Our approach involves Baskakov type operators, the kth order Kantorovich modification of the Baskakov operators, the discrete operators associated with Baskakov operators, Meyer&ndash
Hairy Garlic (Allium subhirsutum) from Sicily (Italy): LC-DAD-MSn Analysis of Secondary Metabolites and In Vitro Biological Properties
2020
Allium subhirsutum, known as hairy garlic, is a bulbous plant widespread in the Mediterranean area and locally used as a food and spice. In the present study, the chemical profile of the ethanolic extracts from bulbs (BE) and aerial parts (APE) were analyzed by HPLC-ESI-MSn, and antioxidant properties were evaluated by DPPH, ABTS and TEAC assays. The traditional use in the diet, and the well documented biological activity of Allium species suggest a potential as a new nutraceutical. For this reason, the potential usefulness of this food can be considered in the treatment and prevention of degenerative Alzheimer disease. For this reason, acetylcholinesterase inhibitory property was investiga…
Two Ways of Understanding Persons: A Husserlian Distinction
2019
This paper clarifies the distinction that Edmund Husserl makes between two different ways of understanding other persons, their actions and motivations: the experiential or empirical way, on the one hand, and the genuinely or authentically intuitive way, on the other hand. The paper argues that Husserl’s discussion of self-understanding clarifies his concept of the intuitive understanding of others and allows us to explicate what is involved in it: not just the grasping of the other’s actual motivations of action but also the grasping of her motivational possibilities. The paper ends by discussing the dynamic character of the personal subject.
La flessibilità dell’organizzazione biologica. Strutture e funzioni alla luce di un modello gerarchico e pluralista dell’omologia
2016
Ciò che si intende mettere in evidenza nel presente saggio è come l’assunzione di un paradigma gerarchico dell’organizzazione biologica consentirebbe di fornire una nuova formulazione del concetto di omologia e conseguentemente dell’unità dell’evoluzione. Si vedrà, infatti, come i concetti di omologia, analogia, omoplasia, convergenza e parallelismo possano essere considerati al di fuori delle opposizioni omologia vs. analogia, omogenia vs. omoplasia, parallelismo vs. convergenza. Piuttosto tali concetti si riferiscono a piani e livelli biologici che sono diversi, ma in relazione l’uno con l’altro nel mondo complesso dell’evoluzione, poichè il mondo biologico è esso stesso gerarchico, ossia…

Herder e la questione dell’Einfühlung. Estetica e teoria della conoscenza fra Mitfühlen e Familiengefühl
2011
Herder is usually considered to be one of the mayor sources of the aesthetics of empaty. The present contribution aims at offering a brief rewiew of some main places in Herder aesthetical theory and at reconstructing the genesis of the family of concepts including fühlen, Gefühl, Mitfühlen, Familiengefühl, in order to understand their relationship with regard to the theory of knowledge, the aesthetics, the politics.
Desarrollo de ciudadanía desde la educación artística y patrimonial: Identidades urbanas en Iberoamérica
2015
En este artículo planteamos una nueva mirada hacia la ciudad, una mirada desde la perspectiva de los docentes. Descubrimos inusuales espacios vinculados al ámbito cultural urbano, geografías aptas para crear escenarios de aprendizaje y para revisar la mirada del profesorado hacia el espacio urbano. Los educadores constituyen un poderoso referente cultural y social capaz de articular el complejo entramado humano que delimita la ciudad. Partimos de las aportaciones que desde la cultura visual y la educación en artes visuales han planteado diversos autores. Nuestro trabajo utiliza metodológicamente el estudio de caso y se asienta en el análisis las encuestas realizadas a docentes de Santiago y…
The oceanic feeling in painterly creativity
2014
The oceanic feeling has been a relatively persistent topic of discussion in both creativity research and aesthetics. Characterized by a sensation of self-boundary dissolution, the feeling has often been reported to involve experiences of fusion with various objects, including works of art. In this article, I will discuss the oceanic feeling in the specific context of painterly creativity. I will begin by arguing that the oceanic feeling cannot be classified as an emotion, mood, or bodily feeling in the established senses of these terms. I will then introduce philosopher Matthew Ratcliffe’s theory of existential feelings to help formulate a more accurate view of the oceanic feeling. More spe…
Neoestetica: un archetipo disciplinare
2011
The paper focuses on Du Bos’ contribution to the birth of aesthetics. Du Bos elaborates – in an anticlassicistical tone – three central notions: 1) that of “artificial passion”, 2) of the taste of “the public” (which is in turn linked to a peculiar conception of “feeling”) and 3) of “artistic genius”. The main tenet will be that such an approach does lead to a “philosophy of fine arts” (or of “artistic beauty”), i.e. the discipline with which modern aesthetics ends up identifying at the end of the xviii century. Hence the theoretical, and not just historical, interest for this author, especially when having an eye to neoaesthetics, viz. aesthetics as begotten by the crisis of the modern aes…
