Many witnesses, many layers: the digital scholarly edition of the Iudicium coci et pistoris (Anth. Lat. 199 Riese)
2014
Il progetto di ricerca messo in cantiere durante l'anno della mia borsa di studio post-doc presso il Centro Linceo Interdisciplinare “B. Segre” dell'Accademia dei Lincei prevede la creazione di un'edizione critica digitale del Iudicium coci et pistoris iudice Vulcano di Vespa (Anth. Lat. 199 Riese), un testo latino tardoantico in versi con una tradizione pluritestimoniale. Tale edizione intende mettere a frutto gli apporti della semiotica, della linguistica e di quella sua parte detta grafologia, applicando le intuizioni teoriche e metodologiche di Tito Orlandi (vd. in particolare Informatica testuale, Laterza: Roma 2010); ed applicare, innovandolo, il markup XML/TEI. In tale edizione, le f…
Does orthographic processing emerge rapidly after learning a new script?
2021
Epub 2020 Aug 11 Orthographic processing is characterized by location-invariant and location-specific processing (Grainger, 2018): (1) strings of letters are more vulnerable to transposition effects than the strings of symbols in same-different tasks (location-invariant processing); and (2) strings of letters, but not strings of symbols, show an initial position advantage in target-in-string identification tasks (location-specific processing). To examine the emergence of these two markers of orthographic processing, we conducted a same-different task and a target-in-string identification task with two unfamiliar scripts (pre-training experiments). Across six training sessions, participants …
Global diversity and geography of soil fungi
2014
Fungi play integral roles in soil nutrient cycling, but the determinants of fungal diversity and biogeographic patterns of key functional groups remain poorly understood. By using pyrosequencing data from hundreds of globally distributed soil samples, we demonstrated fungal diversity that expands upon the taxonomic and molecular diversity recorded so far. Except for ectomycorrhizal symbionts, fungal functional group richness was unrelated to plant diversity and plant-to-fungus richness ratio declined exponentially towards the poles. Climatic factors, followed by edaphic and spatial variables, constituted the best predictors of fungal richness and community composition at the global scale. F…
Reading comprehension in French 1st and 2nd grade children: Contribution of decoding and language comprehension
2006
This paper reports a study conducted with French first-grade and second-grade children (mean age: 6;8 and 7;8 respectively). The first aim was to re-examine the Gough and Tunmer’s (1986) Simple View in assessing the specific contribution of decoding ability and language comprehension to reading comprehension. The second one was to analyse the difficulties of children in reading comprehension. Reading and listening comprehension were assessed using both visual and auditory version of the same test. Decoding ability was assessed by means of a nonword reading test. On the basis of reading comprehension scores, skilled and less skilled comprehenders were contrasted, and then two groups of less …
On the flexibility of letter position coding during lexical processing: the case of Thai.
2012
In Indo-European languages, letter position coding is particularly noisy in middle positions (e.g., judge and jugde look very similar), but not in the initial letter position (e.g., judge vs. ujdge). Here we focus on a language (Thai) which, potentially, may be more flexible with respect to letter position coding than Indo-European languages: (i) Thai is an alphabetic language which is written without spaces between words (i.e., there is a degree of ambiguity in relation to which word a given letter belongs to) and (ii) some of the vowels are misaligned (e.g., [Formula: see text]/ε:bn/ is pronounced as /bε:n/), whereas others are not (e.g., [Formula: see text]/a:p/ is pronounced as /a:p/).…
Plant-herbivorous beetle networks : molecular characterization of trophic ecology within a threatened steppic environment
2015
DNA barcoding facilitates many evolutionary and ecological studies, including the examination of the dietary diversity of herbivores. In this study, we present a survey of ecological associations between herbivorous beetles and host plants from seriously threatened European steppic grasslands. We determined host plants for the majority (65%) of steppic leaf beetles (55 species) and weevils (59) known from central Europe using two barcodes (trnL and rbcL) and two sequencing strategies (Sanger for mono/oligophagous species and Illumina for polyphagous taxa). To better understand the ecological associations between steppic beetles and their host plants, we tested the hypothesis that leaf beetl…
Further evidence that the effects of repetition on subjective time depend on repetition probability
2017
Repeated stimuli typically have shorter apparent duration than novel stimuli. Most explanations for this effect have attributed it to the repeated stimuli being more expected or predictable than the novel items, but an emerging body of work suggests that repetition and expectation exert distinct effects on time perception. The present experiment replicated a recent study in which the probability of repetition was varied between blocks of trials. As in the previous work, the repetition effect was smaller when repeats were common (and therefore more expected) than when they were rare. These results add to growing evidence that, contrary to traditional accounts, expectation increases apparent …
Data from: Stabilising selection on microsatellite allele length at arginine vasopressin 1a receptor and oxytocin receptor loci
2017
The loci arginine vasopressin receptor 1a (avpr1a) and oxytocin receptor (oxtr) have evolutionarily conserved roles in vertebrate social and sexual behavior. Allelic variation at a microsatellite locus in the 5’ regulatory region of these genes is associated with fitness in the bank vole Myodes glareolus. Given the low frequency of long and short alleles at these microsatellite loci in wild bank voles, we used breeding trials to determine whether selection acts against long and short alleles. Female bank voles with intermediate length avpr1a alleles had the highest probability of breeding, while male voles whose avpr1a alleles were very different in length had reduced probability of breedin…
Patterns and rates of nucleotide substitution, insertion and deletion in the endosymbiont of antsBlochmannia floridanus
2009
Genome reduction is a general process that has been studied in numerous symbiotic bacteria associated with insects. We investigated the last stages of genome degradation in Blochmannia floridanus, a mutualistic bacterial endosymbiont of the ant Camponotus floridanus. We determined the tempo (rates of insertion and deletion) and mode (size and number of insertion-deletion events) of the process in the last 200,000 years by analysing a total of 16 intergenic regions in several strains of this endosymbiont from different ant populations. We provide the first calculation of the reduction rate for noncoding DNA in this endosymbiont (2.2 x 10(-8) lost nucleotides/site/year) and compare it with th…
Empagliflozin in heart failure with preserved ejection fraction: decoding its molecular mechanism of action using artificial intelligence
2021
Abstract Rationale The use of sodium-glucose co-transporter 2 inhibitors (SGLT2i) to treat heart failure with preserved ejection fraction (HFpEF) is under investigation in ongoing clinical trials, but the exact mechanism of action is unclear. Here we aimed to use artificial intelligence (AI) to characterize the mechanism of action of empagliflozin in HFpEF at the molecular level. Methods We retrieved information regarding HFpEF pathophysiological motifs and differentially expressed genes/proteins, together with empagliflozin target information and bioflags, from specialized publicly available databases. Artificial neural networks and deep learning AI were used to model the molecular effec…
