Contribution of the Semiological Approach to Deixis-Anaphora in Sign Language: The Key Role of Eye-Gaze.

We address the issue of deixis-anaphora in sign language (SL) discourse, focusing on the role of eye-gaze. According to the Semiological Approach, SL structuring stems from a maximum exploitation of the visuo-gestural modality, which results in two modes of meaning production, depending on the signer's semiotic intent. Involving both non-manual and manual parameters, the first mode, expressing the intent to , uses constructions based on structures, the termed "transfer structures.

Cross-Gender Differences in English/French Bilingual Speakers: A Multiparametric Study.

The present study concerns speech productions of female and male English/French bilingual speakers in both reading and semi-spontaneous speech tasks. We investigated various acoustic parameters: average fundamental sound frequency (F0), F0 range, F0 variance (), vowel formants (F1, F2, and F3), voice onset time (VOT) and H1-H2 (intensity difference between the first and the second harmonic frequencies, used to measure phonation type) in both languages. Our results revealed a significant effect of gender and language on all parameters.

Epileptic seizure prediction based on EEG spikes detection of ictal-preictal states.

Epileptic seizures are known for their unpredictable nature. However, recent research provides that the transition to seizure event is not random but the result of evidence accumulations. Therefore, a reliable method capable to detect these indications can predict seizures and improve the life quality of epileptic patients.

EEG epileptic seizure detection and classification based on dual-tree complex wavelet transform and machine learning algorithms.

The visual analysis of common neurological disorders such as epileptic seizures in electroencephalography (EEG) is an oversensitive operation and prone to errors, which has motivated the researchers to develop effective automated seizure detection methods. This paper proposes a robust automatic seizure detection method that can establish a veritable diagnosis of these diseases. The proposed method consists of three steps: (i) remove artifact from EEG data using Savitzky-Golay filter and multi-scale principal component analysis (MSPCA), (ii) extract features from EEG signals using signal decomposition representations based on empirical mode decomposition (EMD), discrete wavelet transform (DWT), and dual-tree complex wavelet transform (DTCWT) allowing to overcome the non-linearity and non-stationary of EEG signals, and (iii) allocate the feature vector to the relevant class ( , seizure class "ictal" or free seizure class "interictal") using machine learning techniques such as support vector machine (SVM), -nearest neighbor ( -NN), and linear discriminant analysis (LDA).

Cognitive engagement during reading on digital tablet: Evidence from concurrent recordings of postural and eye movements.

The present study utilised a novel combination of eye movement and motion capture recordings to examine cognitive engagement during reading on a hand-held tablet computer. Participants read a multiple-page text with a specific task in mind and after reading recalled the main contents of text from memory. The results showed that head distance from screen was slightly shorter, and readers spent longer time reading task-relevant than irrelevant segments of text and had better memory for task-relevant than irrelevant text information, indicating that there are task-induced momentary changes in engagement during reading.

Early Hypnotic Intervention After Traumatic Events in Children.

Post-traumatic stress disorder is a debilitating condition that can develop after exposure to any potentially traumatic event (natural disaster, physical assault, and car accident). This study focused on four pediatric patients presenting with an early stress response after a motor vehicle accident who were offered early therapeutic and a preventive management by hypnotherapy shortly after exposure to the traumatic event. All patients improved after one or several sessions of hypnosis.

Explaining historical change in terms of LHT: A pluralistic causal framework is needed.

Baumard suggests that the advent, through phenotypic plasticity mechanisms, of future-oriented preferences and creative mindsets in eighteenth-century Great Britain explains the wave of innovations that drove the British Industrial Revolution. We argue that, although this approach is promising, Baumard's model would benefit from being supplemented by demographic, economic, and sociological explanations independent of Life History Theory (LHT).

Iterative Bayesian denoising based on variance stabilization using Contourlet Transform with Sharp Frequency Localization: application to EFTEM images.

Background: Due to the presence of high noise level in tomographic series of energy filtered transmission electron microscopy (EFTEM) images, alignment and 3D reconstruction steps become so difficult. To improve the alignment process which will in turn allow a more accurate and better three dimensional tomography reconstructions, a preprocessing step should be applied to the EFTEM data series.

Results: Experiments with real EFTEM data series at low SNR, show the feasibility and the accuracy of the proposed denoising approach being competitive with the best existing methods for Poisson image denoising.

Referential processing during reading: concurrent recordings of eye movements and head motion.

The present study utilized a new experimental set-up synchronizing eye movements and head motion for investigating referential change occurring in a reading task. We examined the effects of a change in narrative perspective during reading on eye movements and head motion. Forty-four participants read texts on a digital tablet, and both participants' eye movements and head movements were recorded using eye tracker and motion capture.

The economics of secession: a review of legal, theoretical, and empirical aspects.

The aim of this paper is to present a review of the legal, theoretical, and empirical aspects of secessions from an economic perspective. This survey provides interesting insights into recent events such as the Brexit and the threat of secession made for instance by Scotland and Catalonia. International law does not grant a general right to secede, nor does it forbid secession.

Anxiety and depression in patients with multiple sclerosis: The mediating effects of perceived social support.

Background: Social support has been identified as a buffering or intervening variable in stressful life events. Research has demonstrated that greater social support is associated with better mental health in multiple sclerosis (MS), but little is known about its links to specific aspects of mental health. We therefore investigated if and how perceived social support modulates depression, anxiety and fatigue in patients with MS.

Seeking the "museum of the future": Public exhibitions of science, industry, and the social, 1910-1940.

Using as case studies the initiatives developed by two museum curators, the Belgian bibliographer Paul Otlet (1868-1944) and the Austrian social scientist Otto Neurath (1882-1945), and their subsequent collaboration with an extended network of scientists, philanthropists, artists, and social activists, this article provides a portrait of the general movement toward the creation of a new form of museum: the "museum of the future," as Neurath labeled it. This museum would be able to enlighten the people by showing the nature of modern industrial civilization. The promoters of the "museum of the future" intended to reform museum practices by organizing exhibitions of social facts, but also by integrating several dimensions - architecture, commerce, entertainment, pedagogy, and science and technology - to create a holistic frame to address their audience.

Fluctuation in cognitive engagement during reading: Evidence from concurrent recordings of postural and eye movements.

The present study utilized a novel methodological combination of eye tracking and postural movement recordings to study task-induced changes in cognitive engagement during expository text reading. Thirty-three participants read an expository text with a specific task in mind while their eye and postural movements were concurrently recorded, and after reading recalled the text from memory. The results showed that readers spent longer total fixation time and had better memory for task-relevant than irrelevant text information.

Social Cognition Abilities in Patients With Different Multiple Sclerosis Subtypes.

Objectives: Multiple sclerosis (MS) can be associated with impaired social cognition. However, social cognition skills have never been explored in the different subtypes of MS. The first aim of this study was to examine whether MS subtypes differ on the course of social cognition.

Anxiety, emotional processing and depression in people with multiple sclerosis.

Background: Despite the high comorbidity of anxiety and depression in people with multiple sclerosis (MS), little is known about their inter-relationships. Both involve emotional perturbations and the way in which emotions are processed is likely central to both. The aim of the current study was to explore relationships between the domains of mood, emotional processing and coping and to analyse how anxiety affects coping, emotional processing, emotional balance and depression in people with MS.

Is job performance independent from career success? A conceptual distinction between competence and agency.

Adopting a social approach to social judgment, we conducted five studies to validate a conceptual distinction between agency and competence traits. Studies 1-3 revealed that competence traits (e.g.

Evolutionary Algorithms for Boolean Functions in Diverse Domains of Cryptography.

The role of Boolean functions is prominent in several areas including cryptography, sequences, and coding theory. Therefore, various methods for the construction of Boolean functions with desired properties are of direct interest. New motivations on the role of Boolean functions in cryptography with attendant new properties have emerged over the years.

A New Cost Function for Evolution of S-Boxes.

Substitution Boxes (S-Boxes) play an important role in many modern-day cryptographic algorithms, more commonly known as ciphers. Without carefully chosen S-Boxes, such ciphers would be easier to break. Therefore, it is not surprising that the design of suitable S-Boxes attracts a lot of attention in the cryptography community.

A Driving Behaviour Model of Electrical Wheelchair Users.

In spite of the presence of powered wheelchairs, some of the users still experience steering challenges and manoeuvring difficulties that limit their capacity of navigating effectively. For such users, steering support and assistive systems may be very necessary. To appreciate the assistance, there is need that the assistive control is adaptable to the user's steering behaviour.

Preadolescents Solve Natural Syllogisms Proficiently.

"Natural syllogisms" are arguments formally identifiable with categorical syllogisms that have an implicit universal affirmative premise retrieved from semantic memory rather than explicitly stated. Previous studies with adult participants (Politzer, 2011) have shown that the rate of success is remarkably high. Because their resolution requires only the use of a simple strategy (known as ecthesis in classic logic) and an operational use of the concept of inclusion (the recognition that an element that belongs to a subset must belong to the set but not vice versa), it was hypothesized that these syllogisms would be within the grasp of non-adult participants, provided they have acquired the notion of deductive validity.

Distinguishing the desire to learn from the desire to perform: The social value of achievement goals.

We sought to distinguish mastery goals (i.e., desire to learn) from performance goals (i.
