PICTORIAL-C LANGUAGE FOR THE HERMIA-MACHINE
1992
The design and implementation of algorithms on multi-processors machines is hard. The paper describes the general features of the Pictorial C Language (PICL) that is oriented to image analysis. Its integration in the software environment of the HERMIA machine, and the handling of the related interconnecting network topology is also given.
ASPECTS OF THE ECOLOGY AND NATURAL HISTORY OF PARAERGASILUS RYLOVI (COPEPODA, ERGASILIDAE) PARASITIC IN UNIONIDS OF FINLAND
2004
The distribution of Paraergasilus rylovi in 17 populations of unionids was investigated. In 1 unionid population, the parasite was studied regarding host age, size, sex, and the reproductive period (occurrence of egg sacs). Results from pooled material from the years 1987--1989 and 1996 (southern Finland, 11 populations) indicated that Anodonta piscinalis (n = 1,359) is the main host (total mean prevalence 71% and intensity +/-SE of infection 16.4+/-0.6). Pseudanodonta complanata (n = 106) was infected occasionally (3% and 1.3+/-0.3), whereas Unio pictorum (n = 108) and U. tumidus (n = 17) were not infected. Results from 17 A. piscinalis populations showed that P. rylovi occurs in southern …
Differences between young children’s actual, self-perceived and parent-perceived aquatic skills
2021
As drowning is a leading cause of unintentional injury/death in children worldwide, perceptions of their actual aquatic skills are of critical importance. Children’s self-perceptions may influence the risks they take, and parental perceptions may influence the degree of supervision deemed to be necessary for children in and around water. Accordingly, we examined the differences between young children’s actual, self-perceived and parent-perceived aquatic skills. Using a three-way repeated measures ANCOVA, we analyzed data from 134 child-parent dyads (56.0% boys; M age = 7.1, SD = 1.1 years; and 71.6% mothers). We measured self and parental perceptions of the child’s aquatic skills with the …
Authorship in Facilitated Communication: An Analysis of 11 Cases
2014
Abstract. We studied the authorship of messages produced through facilitated communication (FC) for all users of FC in two comprehensive schools in a small city in Finland. The participants were 11 children with intellectual disabilities, including autism, all having used FC from 1 to 3 years. The test conditions involved open and blind information-passing tasks in which the participants were directed to write down the contents of written or pictorial stimuli. The results failed to validate FC as a method of communication for any participant or facilitator. An analysis of the messages produced under the FC condition revealed a large degree of facilitator influence on the content of the mess…
Radiographic and chest CT imaging presentation and follow-up of COVID-19 pneumonia: a multicenter experience from an endemic area.
2020
COVID-19 has infected more than 2 million people in the world in less than 5 months outbreak. Chest imaging is recommended for triage of suspected cases of COVID-19 with moderate-severe clinical features and high pre-test probability of disease, and may help for patient follow-up and to identify patients at higher risk of disease worsening. This pictorial essay illustrates typical and uncommon imaging findings of COVID-19 pneumonia and the role of imaging for patient management.
A Facilitatory Effect of Perceptual Incongruity on Target-Source Matching in Pictorial Metaphors of Chinese Advertising: EEG Evidence
2020
Using evoked response potentials, we investigated the implicit detection of incongruity during target-source matching in pictorial metaphors of Chinese advertising. Participants saw an image of a product (the target in a visual metaphorical relationship), and then made a same-different judgment in response to a second image (the source in a visual metaphorical relationship) which was (in)congruous to the first image in terms of shape and/or function. We collected behavioral (button-press reaction time and accuracy), and neural (N270, delta and theta band activity) measures. The time-frequency analysis showed faster processing of incongruous visual information. Moreover, shape and conceptual…
Early Signs of Mathematics Anxiety?
2012
Abstract Mathematics anxiety refers to individual's negative affect when engaging in numerical and mathematical tasks. Researchers have recently connected high math anxiety to lower performance on math tasks, developmental dyscalculia, and lower self-efficacy towards math learning. Math anxiety scales have been made and validated mainly for secondary school and high school students. In our paper we are looking for early signs of math anxiety using a Pictorial Test (37 pictures) which we have developed for 6 to 8 year old children. Children were asked to concentrate on one picture at a time and to write down spontaneously their emotional and mathematical ideas. Most powerful sources of sadne…
Mitchell in Italia
2017
L'articolo, postfazione al libro Pictorial Turn. Saggi di cultura visuale, mette in evidenza e collega gli studi italiani che hanno subito l'influenza delle teorizzazioni di WJT Mitchell e che hanno contribuito a creare la corrente italiana della visual culture attraverso discipline differenti come le letterature comparate, l'estetica, la filosofia, gli studi sul cinema, persino l'architettura.
Evolution des biominéralisations nacrées chez les mollusques : caractérisation moléculaire des matrices coquillières du céphalopode nautiloïde Nautil…
2008
In metazoan, molluscan shells are one of the most fascinating examples for the investigation of the calcium carbonate biomineralization phenomenon. These exoskeletons are secreted by the outer epithelium of the calcifying mantle. They are composed of 95% of mineral – calcite and/or aragonite -, the rest of the shells being constituted by a mixture of proteins, glycoproteins and polysaccharides, called the organic matrix. This calcifying matrix is directly involved in biomineralization. This PhD work is focussed on the characterization of organic components associated to the nacreous layer. In molluscs, the nacre is observed in shells of extent species of bivalves, gastropods, cephalopods an…
Visual Imagery, Mental Models, and Reasoning
2006
Abstract: The focus of this paper is the relation between Steven Kosslyn’s visual mental images and Johnson-Laird’s mental models. Knauff et al. presented empirical evidence and a challenging argument for the hypothesis that in fact “visual imagery impedes reasoning.” I argue that these results may look embarrassing for pictorialists, but closer inspection suggests that they are actually harmless. I argue that the presented evidence fails to show that imagery impedes reasoning. I present some objections to the explanation proposed by Knauff and Johnson-Laird by pointing out some terminological and conceptual problems. Afterwards, I sketch an alternative explanation, which is more pictoriali…
