No le digan loco a Bill. Sobre internalismo y externalismo de las razones para la acción

2011

En este trabajo analizaré dos concepciones de la racionalidad práctica – bien conocidas y debatidas en la literatura contemporánea – con el propósito de mostrar que una es superior a la otra. La primera concepción, que será la defendida en este trabajo, es una concepción denominada “formal” o “internalista”, mientras que la segunda podría denominarse “sustancial” o “externalista”. En particular, defenderé una concepción formal moderada, análoga a la de Bernard Williams, según la cual Juan tiene una razón para hacer X, si y sólo si hacer X representa un medio (considerado) suficiente para satisfacer un deseo que él tendría luego de haber realizado el procedimiento argumentativo racional.

Classification of Pollen Apertures Using Bag of Words

2013

International audience; The taxonomical recognition of microscopic biological parti- cles such as pollen and spores is relevant for medical and aerobiological applications. Focusing on an accurate and automatic vision-based pollen recognition system, we propose a method for classification of pollen aper- tures based on bag-of-words strategy, with the ability of learning new types from different taxa without the need of new algorithms. Results demonstrate suitable performance and ability to add new taxa.

Effect of dual biotic stress on plant volatile synomones used by an egg parasitoid

Plants respond to arthropod herbivory with the induction of volatiles called herbivore-induced plant volatiles (HIPVs). These volatiles appear to be important sources of information that attract parasitoids. Parasitic wasps foraging decisions are often affected by community characteristics such as community diversity and complexity. As part of a complex habitat, the presence of unsuitable hosts (non-host) may affect foraging behavior of parasitoids. In this chapter, we outline the importance of the presence of unsuitable herbivores on the behavioral responses of parasitoids. First we review the foraging behavior of parasitoid in tritrophic interaction. Then we focus on foraging behavior by …

Valutazione produttive e qualitative di Timilie - Produttive and qualitative evaluation of timilie

2009

Riassunto: Gli autori riportano i primi risultati produttivi e qualitativi relativi a 4 popolazioni di timilie raccolte in diversi ambienti pedoclimatici della Sicilia occidentale. Attraverso uno schema sperimentale non ripetuto sono state valutate 720 accessioni ed è emersa una elevata variabilità tra e intra popolazioni. Dalle analisi qualitative delle accessioni collezionate sono emerse peculiari caratteristiche qualitative della granella che ne fanno intravedere l’uso sia per la produzione di prodotti tipici sia per il trasferimento in varietà ampiamente diffuse e coltivate. Abstract: Productive and qualitative results on four “timilia” population from different West Sicilian pedoclimat…

L`ANGIOGENESI NEL SISTEMA NERVOSO ANGIOGENESIS IN THE NERVOUS SYSTEM

2010

Comportamento bioagronomici di genotipi di triticale in due ambienti mediterranei. Bioagronomic behaviour of triticale in two Mediterranean Environme…

2009

Tra i cereali minori il triticale, occupa un posto di primaria importanza sia per gli aspetti agronomici e sia per gli usi possibili della coltura. L’ibrido, nato dall’esigenza di associare in un individuo alle buone caratteristiche produttive dei frumenti, la resistenza della segale potrebbe rappresentare, infatti, una valida alternativa colturale negli ordinamenti asciutti degli ambienti marginali. L’intenso lavoro di miglioramento genetico ha consentito la costituzione di varietà, migliorate sia per l’utilizzazione animale che per l’alimentazione umana. Inoltre, l’accresciuta consapevolezza dei consumatori, degli effetti benefici derivanti dalla diversificazione dei cereali nella dieta, …

Can individuals’ neutralization techniques be overcome? A field experiment on password policy

2020

Individuals’ lack of adherence to password security policy is a persistent problem for organizations. This problem is especially worrisome because passwords remain the primary authentication mechanism for information systems, and the number of passwords has been increasing. For these reasons, determining methods to improve individuals’ adherence to password-security policies constitutes an important issue for organizations. Extant research has shown that individuals use neutralization techniques, i.e., types of rationalizations, to disregard organizational information-security policies. What has not been determined from extant information security research is whether these neutralizations c…

Patterns in words and languages

2004

AbstractA word p, over the alphabet of variables E, is a pattern of a word w over A if there exists a non-erasing morphism h from E∗ to A∗ such that h(p)=w. If we take E=A, given two words u,v∈A∗, we write u⩽v if u is a pattern of v. The restriction of ⩽ to aA∗, where A is the binary alphabet {a,b}, is a partial order relation. We introduce, given a word v, the set P(v) of all words u such that u⩽v. P(v), with the relation ⩽, is a poset and it is called the pattern poset of v. The first part of the paper is devoted to investigate the relationships between the structure of the poset P(v) and the combinatorial properties of the word v. In the last section, for a given language L, we consider …

Neuropsychologic phenotypes in familial hemiplegic migraine

2003

Familial hemiplegic migraine (FHM) is a rare autosomal dominant-type migraine with aura. Attacks are characterised by hemiparesis in addition to other aura and migraine symptoms. Few studies have examined the influence of FHM on cognitive functions. This study was aimed to investigate neuropsychological functions in 3 adolescent siblings suffering from FHM assessed six months after the last attack. No relevant deficits were found on a battery of multisectorial tests exploring cognitive functions. Sporadic FHM attack therefore seems not to affect cognition in these patients, at least far from the crises.

A further analysis of secretory structures of some taxa belonging to the genus Hypericum (Clusiaceae) in relation to the leaf vascular pattern

2014

This work extends knowledge about the distribution of secretory structures (black nodules, translucent glands, and type A and B secretory canals) to other species of the genus Hypericum L., as only H. perforatum L. appears to have been widely investigated. Moreover, the current study was extended to include leaf vascular patterns. In the species studied, a possible correlation between the presence of black nodules and a particular biological form, that of hemicryptophytes scapose perennials such as H. perfoliatum L., H. perforatum L., H. pubescens Boiss., H. tetrapterum Fr., and H. triquetrifolium Turra, was noted. These black nodules are not present in H. androsaemum L. and H. hircinum L.,…
