High cooperation and welfare despite — and because of — the threat of antisocial punishments and feuds
2021
Cooperation can be difficult to sustain when there is a temptation to free-ride on the efforts of others. In experiments, peer punishment often stabilizes cooperation but fails to improve earnings because of the costs associated with punishment. In addition, antisocial use of punishment—punishing cooperators, counterpunishing, and feuding—often leads to lower cooperation and earnings. The current study investigated if powerful individuals—individuals who can punish without cost or who are immune from punishment—police the antisocial use of punishment, thus reducing the undesirable effects of punishment. In order to create ample opportunities for antisocial punishment and identify the motive…
Anodal Transcranial Direct Current Stimulation Over Prefrontal Cortex Slows Sequence Learning in Older Adults
2022
Aging is associated with declines in sensorimotor function. Several studies have demonstrated that transcranial direct current stimulation (tDCS), a form of non-invasive brain stimulation, can be combined with training to mitigate age-related cognitive and motor declines. However, in some cases, the application of tDCS disrupts performance and learning. Here, we applied anodal tDCS either over the left prefrontal cortex (PFC), right PFC, supplementary motor complex (SMC), the left M1, or in a sham condition while older adults (n = 63) practiced a Discrete Sequence Production (DSP), an explicit motor sequence, task across 3 days. We hypothesized that stimulation to either the right or left P…
Catalogue of the Diptera (Insecta) of Morocco— an annotated checklist, with distributions and a bibliography
2022
The faunistic knowledge of the Diptera of Morocco recorded from 1787 to 2021 is summarized and updated in this first catalogue of Moroccan Diptera species. A total of 3057 species, classified into 948 genera and 93 families (21 Nematocera and 72 Brachycera), are listed. Taxa (superfamily, family, genus and species) have been updated according to current interpretations, based on reviews in the literature, the expertise of authors and contributors, and recently conducted fieldwork. Data to compile this catalogue were primarily gathered from the literature. In total, 1225 references were consulted and some information was also obtained from online databases. Each family was reviewed and the c…
The red ear syndrome and migraine: the role of the parasympathetic system in a complex and intriguing clinical association
2010
Background and aims: The red ear syndrome (RES) is a rare syndrome characterized by burning pain and cutaneous erythema in the ear. It is probably due to an autonomic dysfunction, because of a hypofunction of sympathetic and/or a hyperactivity of parasympathetic control. We have previously described an intriguing association with migraine. In the present study, we have investigated the pathophysiological links between the RES and the clinical features of migraine, and pointed out the crucial role of the parasympathetic system. Methods: A total of 172 young migraine sufferers (92 M and 80 F, aged 4–17 years) underwent a clinical and instrumental evaluation. A semi-structured interview about …
The SO2F2 quasi-spherical top: Correspondence between tensorial and Watson's formalisms
2006
Abstract The SO2F2 quasi-spherical top molecule with C2v symmetry is considered as a distorted spherical top deriving from the SO 4 2 − tetrahedral ion. We present here a detailed correspondence between the tensorial formalism using the Td⊃C2v reorientation and the usual Hamiltonian of Watson. We have also performed ab initio calculations in order to determine the centrifugal distorsion constants in the vibrational ground state.
Regulación espacio-temporal de la homeostasis del cobre en Arabidopsis thaliana
2013
El cobre y el hierro son nutrientes esenciales para los seres vivos aerobios y sus potenciales redox son utilizados en las reacciones de transferencia de electrones. Sin embargo, esta capacidad redox resulta tóxica cuando los metales de transición entran en contacto con intermediarios del metabolismo aerobio, conocidos como ROS (reactive oxygen species). Los organismos aerobios han desarrollado estrategias homeostáticas para mantener los niveles de los metales adecuados en la célula y distribuir, espacial y temporalmente, los procesos de transporte y tráfico intracelular de metales para minimizar el daño oxidativo al resto de procesos celulares. En este sentido, recientemente se ha demostra…
Skala Niesprawności Neurologicznej Szpitala Guy jako istotne narzędzie do oceny objawów występujących u osób z SM
2017
Skala Niesprawności Neurologicznej Szpitala Guy (GNDS, The Guy’s Neurological Disability Scale) jest istotnym narzędziem służącym do pomiaru niepełnosprawności u osób ze stwardnieniem rozsianym. Służy ona do określenia poziomu funkcjonowania w dwunastu ważnych obszarach. Celem obecnych badań było opracowanie polskiej wersji językowej skali GNDS i sprawdzenie jej trafności, rzetelności oraz przydatności do oceny niepełnosprawności występującej u osób ze stwardnieniem rozsianym. Grupę badaną stanowiło 175. pacjentów z rozpoznaniem stwardnienia rozsianego. W badaniu wykorzystano Rozszerzoną Skalę Niewydolności Ruchowej – EDSS, Skalę Niesprawności Neurologicznej Szpitala Guy – GNDS, Skalę Akcep…
Validating Habitual and Goal-Directed Decision-Making Performance Online in Healthy Older Adults
2021
Everyday decision-making is supported by a dual-system of control comprised of parallel goal-directed and habitual systems. Over the past decade, the two-stage Markov decision task has become popularized for its ability to dissociate between goal-directed and habitual decision-making. While a handful of studies have implemented decision-making tasks online, only one study has validated the task by comparing in-person and web-based performance on the two-stage task in children and young adults. To date, no study has validated the dissociation of goal-directed and habitual behaviors in older adults online. Here, we implemented and validated a web-based version of the two-stage Markov task usi…
Clinical Onset and Multiple Sclerosis Relapse after SARS-CoV-2 Infection
2021
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been associated with several neurological disorders including headache, facial palsy, encephalitis, stroke, demyelinating disorders. The present report will discuss cases of multiple sclerosis (MS) onset and relapse both beginning early after SARS-CoV-2 infection. In both cases, magnetic resonance imaging (MRI) showed widespread bilateral subcortical and periventricular active lesions. Serum IgG against SARS-CoV-2 Spike antigens confirmed seroconversion with titers that are considered not definitely protective against possible reinfection. We hypothesize that SARS-CoV-2 infection, as previously reported for other vir…
