Dynamic Functional Connectivity Captures Individuals’ Unique Brain Signatures
2020
Recent neuroimaging evidence suggest that there exists a unique individual-specific functional connectivity (FC) pattern consistent across tasks. The objective of our study is to utilize FC patterns to identify an individual using a supervised machine learning approach. To this end, we use two previously published data sets that comprises resting-state and task-based fMRI responses. We use static FC measures as input to a linear classifier to evaluate its performance. We additionally extend this analysis to capture dynamic FC using two approaches: the common sliding window approach and the more recent phase synchrony-based measure. We found that the classification models using dynamic FC pa…
Exploring Design Cognition in Voice-Driven Sound Sketching and Synthesis
2021
Conceptual design and communication of sonic ideas are critical, and still unresolved aspects of current sound design practices, especially when teamwork is involved. Design cognition studies in the visual domain represent a valuable resource to look at, to better comprehend the reasoning of designers when they approach a sound-based project. A design exercise involving a team of professional sound designers is analyzed, and discussed in the framework of the Function-Behavior-Structure ontology of design. The use of embodied sound representations of concepts fosters team-building and a more effective communication, in terms of shared mental models.
Sense Equivalence in plWordNet to Princeton WordNet Mapping
2019
Abstract Though the interest in use of wordnets for lexicography is (gradually) growing, no research has been conducted so far on equivalence between lexical units (or senses) in inter-linked wordnets. In this paper, we present and validate a procedure of sense-linking between plWordNet and Princeton WordNet. The proposed procedure employs a continuum of three equivalence types: strong, regular and weak, distinguished by a custom-designed set of formal, semantic and translational features. To validate the procedure, three independent samples of 120 sense pairs were manually analysed with respect to the features. The results show that synsets from the two wordnets linked by interlingual syno…
¿Una feria de cambios a la valenciana? Debate financiero y energía emprendedora en el siglo XVII
2020
In 1619 Philip IV sent to print a Real Pragmatic [Royal Pragmatic legislation] that would regulate changes between Valencia and Medina del Campo being introduced by Valencian merchant families to enable them to receive interest on their loans without being accused of usury. Only three years later, in 1622, the Republic of Genoa inaugurated the exchange fairs of Novi Ligure, with which the Genoese consolidated their international position in the international credit market. These apparently independent circumstances constitute an important episode for international financial knowledge and the transformation of the Mediterranean credit market during the seventeenth century. Studying financial…
The Semiotics of Test Design: Conceptual Framework on Optimal Item Features in Educational Assessment Across Cultural Groups, Countries, and Languages
2021
This paper offers a conceptual framework on test design from the perspective of social semiotics. Items are defined as arrangements of features intended to represent information, convey meaning, and capture information on the examinees’ knowledge or skills on a given content. The conceptual framework offers a typology of semiotic resources used to create items and discusses item representational complexity—the multiple ways in which the semiotic resources of an item are related to each other—and item semiotic alignment—the extent to which examinees share cultural experience encoded by items. Since the ability to make sense of items is shaped by the examinees’ level of familiarity with the s…
An attraction-based cellular automaton model for generating spatiotemporal population maps in urban areas
2015
We develop a cellular automaton (CA) model to produce spatiotemporal population maps that estimate population distributions in an urban area during a random working day. The resulting population maps are at 50 m and 5 minutes spatiotemporal resolution, showing clearly how the distribution of population varies throughout a 24-hour period. The maps indicate that some areas of the city, which are sparsely populated during the night, can be densely populated during the day. The developed CA model assumes that the population transition trends follow dynamics and propagation patterns similar to a contagious disease. Thus, our model designed to change the states of each grid cell (stable or dynami…
Investigating Mobility Gaps in University Campuses
2018
The objective of the present research is to carry out a gap analysis between current mobility situations and the needs, future plans and priorities regarding a number of thematic areas on the issue of mobility in university campuses. For this purpose, an interview was conducted involving 36 experts from seven Southern European Universities. More specifically, experts from each university were asked to analyse and rate both the current and the desired situation in the campus under their responsibility with focus on the following thematic areas: parking management, soft modes infrastructure, public transport, car related issues, road infrastructure, environment and energy, mobility management…
Different Languages - Different Sentence Types? On Exclamative Sentences
2016
It is not equally easy for all languages to establish an exclamative sentence type. It seems the easiest for those languages that feature a morphological marking for an exclamative sentence type like Turkish or Vietnamese. English on the other hand is a language that does not mark exclamative clauses with an easily identifiable marker but uses certain preferred constructions, which allow us to separate a class of ‘exclamative sentences’ from other sentence types. However, there is another class of languages for which it is even harder to determine if ‘exclamative sentences’ exist as a sentence type. In those languages, these sentences share a striking amount of formal properties with senten…
Does the source matter?
2018
Abstract This article provides an insight into the expression of reportative evidentiality in Spanish scientific articles published between 1799 and 1920. Central to the discussion is the presence and specificity of sources in reportative constructions. While contemporary scientific discourse prioritizes the use of specific, reportative-quotative evidentials, this is not a constant feature of articles analyzed in this study. In order to trace this historical variation, we established a classification of reportative constructions according to the specificity of the evidence they convey and we conducted both qualitative and quantitative analyses. According to our results, different specificit…
Estimating the dwarfing rate of an extinct Sicilian elephant.
2021
Summary Evolution on islands, together with the often extreme phenotypic changes associated with it, has attracted much interest from evolutionary biologists. However, measuring the rate of change of phenotypic traits of extinct animals can be challenging, in part due to the incompleteness of the fossil record. Here, we use combined molecular and fossil evidence to define the minimum and maximum rate of dwarfing in an extinct Mediterranean dwarf elephant from Puntali Cave (Sicily). 1 Despite the challenges associated with recovering ancient DNA from warm climates, 2 we successfully retrieved a mitogenome from a sample with an estimated age between 175,500 and 50,000 years. Our results sugge…
