Unifying prospective and retrospective interval-time estimation: A fading-Gaussian activation-based model of interval-timing

2014

International audience; Hass and Hermann (2012) have shown that only variance-based processes will lead to the scalar growth of error that is characteristic of human time judgments. Secondly, a major meta-review of over one hundred studies (Block et al., 2010) reveals a striking interaction between the way in which temporal judgments are queried and cognitive load on participants’ judgments of interval duration. For retrospective time judgments, estimates under high cognitive load are longer than under low cognitive load. For prospective judgments, the reverse pattern holds, with increased cognitive load leading to shorter estimates. We describe GAMIT, a Gaussian spreading-activation model,…

Gender Equality Perceptions of Future Engineers

2018

Gender bias is important in our society not only from the point of view of ethics and human rights but also from a pragmatic engineering point of view. Universities are aware of this issue and deve...

A gender- based approach to the current situation of Spanish dentists

2021

Background To determine the perception of Spanish dentists about the situation of the profession nowadays and how the changes occurred in dental workforce (in number and gender of the past twenty years) have affected their personal and professional lives, under a gender-based approach. Material and Methods An online survey comprising of 51 opinion and socio-economic questions, divided into 9 sections of different topics, which was administered between the members of 13 professional associations. Chi-squared tests were calculated (p<0.05). Results Valid responses were received from 422 participants with a mean age of 41 years old and 66% of female dentists. Most dentists considered their sel…

Gender violence in migration: Voices of migrant women in Sicily

2015

Migrant women constitute a growing reality in Italy, also with reference to violence among family members. In particular, violence endured by the foreign female takes on a character of ‘dual violence,’ the violence experienced within the relationship is supplemented by the violence from the social context, which often isolates her, or even expels her following her ‘coming out into the open.’ The article presents extensive reflections emerging from the results of research carried out in 2012 in Sicily, aiming to explore the experience and perception of family violence and the possible influence of the migratory experience on changes in the forms and implications of family violence. The refle…

This article analyzes children’s experiences and their perceived sense of belonging to brothers and sisters to assess the significance of social and biological ties for developing identity. Specifically, this article aims to highlight the significance of siblings for children moving from homes to foster homes and back to their original homes again. Most children participating in this study emphasized the continuity of biological relations with their siblings as important for their identity and sense of belonging. At the same time, social ties to both siblings and foster siblings had significance for their perception of themselves. A sense of belonging and identity are, thus, shown to devel…

Characteristics of neuronal systems in the visual cortex

1987

The coupling complexity of cortical areas makes it very difficult to analyse them experimentally. Studies of model systems provide the possibility of adapting the analysis to the available data base and elaborating the fundamental properties that depend on the structure of the system. We propose a model system of variable complexity that is spatially two-dimensional and time-dependent, uses feedback for iteration and smoothing, includes the mapping of the cortical networks and can be nonlinear as the case requires. Combining such elementary systems on the basis of neuroanatomical findings enables us to simulate cortical mappings and to interpret neurophysiological data. The decisive factor …

Forma mentis networks map how nursing and engineering students enhance their mindsets about innovation and health during professional growth

2020

Reconstructing a “forma mentis”, a mindset, and its changes, means capturing how individuals perceive topics, trends and experiences over time. To this aim we use forma mentis networks (FMNs), which enable direct, microscopic access to how individuals conceptually perceive knowledge and sentiment around a topic, providing richer contextual information than machine learning. FMNs build cognitive representations of stances through psycholinguistic tools like conceptual associations from semantic memory (free associations, i.e., one concept eliciting another) and affect norms (valence, i.e., how attractive a concept is). We test FMNs by investigating how Norwegian nursing and engineering stude…

Identifying Pathways to Computer Science : The Long-Term Impact of Short-Term Game Programming Outreach Interventions

2019

Short-term outreach interventions are conducted to raise young students’ awareness of the computer science (CS) field. Typically, these interventions are targeted at K–12 students, attempting to encourage them to study CS in higher education. This study is based on a series of extra-curricular outreach events that introduced students to the discipline of computing, nurturing creative computational thinking through problem solving and game programming. To assess the long-term impact of this campaign, the participants were contacted and interviewed two to five years after they had attended an outreach event. We studied how participating in the outreach program affected the students’ perceptio…

An efficient data model for energy prediction using wireless sensors

2019

International audience; Energy prediction is in high importance for smart homes and smart cities, since it helps reduce power consumption and provides better energy and cost savings. Many algorithms have been used for predicting energy consumption using data collected from Internet of Things (IoT) devices and wireless sensors. In this paper, we propose a system based on Multilayer Perceptron (MLP) to predict energy consumption of a building using collected information (e.g., light energy, day of the week, humidity, temperature, etc.) from a Wireless Sensor Network (WSN). We compare our system against four other classification algorithms, namely: Linear Regression (LR), Support Vector Machin…

An overall description of retinotopic mapping in the cat's visual cortex areas 17, 18, and 19.

1985

Mathematical functions are derived which model the retinotopic mapping in the cat's visual cortical areas 17, 18, and 19. All three mappings are simple modifications of a complex power function with an exponent of 0.43. This function is decomposed so as to give an intermediate stage which is common to all three mappings and can be regarded as a model of the lateral geniculate nucleus mapping. The influence of retinotopic mapping on visual receptive fields was studied. The results show that a dependence of the receptive field properties on the position in the visual field is to be expected.
