Does One Size Fit All? A Case Study to Discuss Findings of an Augmented Hands-Free Robot Teleoperation Concept for People with and without Motor Disabilities

Hands-free robot teleoperation and augmented reality have the potential to create an inclusive environment for people with motor disabilities. It may allow them to teleoperate robotic arms to manipulate objects. However, the experiences evoked by the same teleoperation concept and augmented reality can vary significantly for people with motor disabilities compared to those without disabilities. In this paper, we report the experiences of Miss L., a person with multiple sclerosis, when teleoperating a robotic arm in a hands-free multimodal manner using a virtual menu and visual hints presented through the Microsoft HoloLens 2. We discuss our findings and compare her experiences to those of people without disabilities using the same teleoperation concept. Additionally, we present three learning points from comparing these experiences: a re-evaluation of the metrics used to measure performance, being aware of the bias, and considering variability in abilities, which evokes different experiences. We consider these learning points can be extrapolated to carrying human–robot interaction evaluations with mixed groups of participants with and without disabilities.

The short and long-term effects of aerobic, strength, or mixed exercise programs on schizophrenia symptomatology

The purpose of this study was to compare the effects of three different physical exercise programs on the symptomatology, body composition, physical activity, physical fitness, and quality of life of individuals with schizophrenia. A total of 432 patients were assessed for eligibility and 86 were randomized into the aerobic (n = 28), strength (n = 29) or mixed (n = 29) groups. Positive, negative, and general symptoms of psychosis, body mass index (BMI), physical activity (IPAQ-SF), physical fitness (6-min walk test [6MWT] and hand-grip strength [HGS]), and quality of life (WHOQUOL-BREF) were assessed at baseline, post-intervention (16 weeks), and at 10-months. Our results at 16 weeks showed significant improvements in all three groups in the negative, general, and total symptoms with moderate to large effect sizes (P < 0.01, ηp2 > 0.11), no change in the BMI, 6MWT or IPAQ-SF, and a significant improvement in the HGS test in the strength and mixed groups (P ≤ 0.05, ηp2 > 0.08). Nonetheless, all the improvements had disappeared at 10 months. We concluded that 3 weekly sessions of a moderate to vigorous progressive exercise program for 16 weeks improved the symptomatology of individuals with schizophrenia in all three groups, with no differences between them. However, the effects had declined to baseline levels by the 10-month follow-up, suggesting that exercise interventions should be maintained over time.

Over-Time Trends in Incivility on Social Media: Evidence From Political, Non-Political, and Mixed Sub-Reddits Over Eleven Years

Incivility in social media has become a major concern of the public, who perceive uncivil online interactions to be both widespread and increasing. This study provides a descriptive account of incivility dynamics over the past 11 years by examining the trends of incivility in three main categories of social media interactions: political, mixed, and non-political. Using longitudinal data from Reddit that accounts for 95% of the entire Reddit universe across 11 years and relying on the combination of supervised machine learning models and traditional statistical inference, the study found that incivility consistently represents around 10% of total Reddit comments. Additionally, political groups tend to be more uncivil, and discussions in mixed groups that are not overtly political but nevertheless discuss politics are less uncivil than in political groups. We also found that the fluctuations of incivility correspond to offline events and platform-specific policies.

Sociability strongly affects the behavioural responses of wild guanacos to drones

Drones are being increasingly used in research and recreation but without an adequate assessment of their potential impacts on wildlife. Particularly, the effect of sociability on behavioural responses to drone-associated disturbance remains largely unknown. Using an ungulate with complex social behaviour, we (1) assessed how social aggregation and offspring presence, along with flight plan characteristics, influence the probability of behavioural reaction and the flight distance of wild guanacos (Lama guanicoe) to the drone's approach, and (2) estimated reaction thresholds and flight heights that minimise disturbance. Sociability significantly affected behavioural responses. Large groups showed higher reaction probability and greater flight distances than smaller groups and solitary individuals, regardless of the presence of offspring. This suggests greater detection abilities in large groups, but we cannot rule out the influence of other features inherent to each social unit (e.g., territoriality) that might be working simultaneously. Low flight heights increased the probability of reaction, although the effect of drone speed was less clear. Reaction thresholds ranged from 154 m (solitary individuals) to 344 m (mixed groups), revealing that the responsiveness of this guanaco population to the drone is the most dramatic reported so far for a wild species.

Interactivité, co-construction, quand l’outil numérique dé-hiérarchise le rapport entre enseignant-e-s et étudiant-e-s en langue

As a teacher-researcher at ISIT, I had to maintain pedagogical continuity with my colleagues from the very first day of the lockdown, and to ensure all my lectures and online workshops, with some time adjustments and extra breaks for long courses. I teach undergraduate Chinese to French translation to French and Chinese students, in mixed groups of speakers of both languages. I also teach general and comparative terminology at graduate level. In this article, I only deal with the devices implemented in my undergraduate general Chinese to French translation courses. This new teaching format has given me the opportunity to test tools in both synchronous and asynchronous formats. I would like to present two of these tools and the features that interested me most for synchronous use in Chinese to French translation classes.

Superparasitism and fitness parameters in three native wasp parasitoids (Braconidae: Opiinae) of the Mexican fruit fly, Anastrepha ludens (Diptera: Tephritidae)

Knowledge on reproductive strategies and host use in insect parasitoids is fundamental for biological control purposes. Superparasitism and multiparasitism, oviposition in a previously parasitized host by a female of the same or different species, respectively, may impact pest management decisions. Our objective was to determine the occurrence of superparasitism and multiparasitism in three species of native larval−pupal solitary endoparasitoids that attack Anastrepha Shiner species (Diptera: Tephritidae) in the Neotropical region, and the possible effect on offspring fitness parameters. Doryctobracon crawfordi (Viereck), Utetes anastrephae (Viereck), and Opius hirtus (Fischer) occur in sympatry in Mexico, and are currently under consideration for use as biocontrol agents. Experiments were conducted under laboratory conditions with females acting alone (self-superparasitism), females in groups of the same species (conspecific superparasitism), and females in mixed groups (multiparasitism). Our results showed that self-superparasitism is an uncommon strategy in the three native species and is rare under conditions of intraspecific competition. In the case of multiparasitism, a higher number of immature stages of U. anastrephae was observed, compared to those of D. crawfordi and O. hirtus. However, it is not clear yet if this was due to some adult female trait or to the competitive ability of the larvae. We conclude that most females of the native species studied appeared to avoid superparasitism, specifically when acting alone, suggesting a high discrimination ability, which is probably a result of a close relationship and evolutionary history with Anastrepha hosts.

MODULATORY ANTI- DIARRHEAL EFFECTS OF ASCORBIC ACID IN SWISS ALBINO MICE

Ascorbic acid (AA) has been reported for the management of diarrhea. The anti-diarrheal potential and modulatory activities of AA on some commonly used anti-diarrheal drugs were investigated. For this purpose, the activities of AA on castor oil-induced diarrhea in Swiss mice were examined. As standard anti-diarrheal agents, we used prazosin, propranolol, loperamide, and nifedipine with or without AA. The results revealed that AA at 25 mg/kg (i.p.) and all other standard drugs exhibited significant (p < 0.05) diarrheal attenuating activities in mice. However, the impact was more pronounced in the loperamide and propranolol groups. AA administrated with prazosin and propranolol had a higher rate of latent periods and a lower rate of diarrheic secretion during the study period (4 h) than that of the other single or mixed groups. Furthermore, a molecular docking study illustrated that AA displayed good binding affinities with (α1) (–5.2 Kcal/mol), α2b (–5.4 Kcal/mol), α2c (-5.6 Kcal/mol), β1(–5.3 Kcal/mol) and β2(–6.4 Kcal/mol) adrenoceptors. Of note, AA exerted a significant anti-diarrheal effect and it was seen to modulate the anti-diarrheal effects of α- and β-adrenergic receptor blocking agents in Swiss mice.

The effects of aerobic, strength, or mixed exercise programs on schizophrenia symptomatology: a randomized clinical trial with a 10-month follow-up

The purpose of this study was to compare the effects of three different physical exercise programs on the symptomatology, body composition, and physical fitness of individuals with schizophrenia. A total of 432 patients were assessed for eligibility and 86 were randomized into the aerobic (n = 28), strength (n = 29) or mixed (n = 29) groups. Positive, negative, and general symptoms of psychosis, body mass index (BMI), and physical fitness (6-minute walk test [6MWT] and hand-grip strength [HGS]) were assessed at baseline, post-intervention (16 weeks), and at 10-months. Our results at 16 weeks showed significant improvements in all three groups in the negative, general, and total symptoms with moderate to large effect sizes (P < 0.01, ηp2 > 0.11), no change in the BMI or 6MWT, and a significant improvement in the HGS test in the strength and mixed groups (P ≤ 0.05, ηp2 > 0.08). Nonetheless, all the improvements had disappeared at 10 months. We concluded that 3 weekly sessions of a moderate to vigorous progressive exercise program for 16 weeks improved the symptomatology of schizophrenic patients, regardless the type of exercise they performed. However, the effects had declined to baseline levels by the 10-month follow-up, suggesting that exercise interventions should be maintained over time.

BINARY OR NON-BINARY? GENDER MORPHOLOGY IN SPANISH: DIFFERENCES DEPENDENT ON THE TASK

There is empirical evidence in different languages on how the computation of gender morphology during psycholinguistic processing affects the conformation of sex-generic representations. However, there is no empirical evidence on the processing of non-binary morphological variants in Spanish (-x or -e) in contrast to the generic masculine variant (-o). To analyze this phenomenon, we conducted two experiments: an acceptability judgment task and a sentence comprehension task. The results show differences depending on the task. So, the underlying processes that are put into play in each one generate different effects. In acceptability judgments, which involve strategic processes mediated by beliefs and the linguistic norm, the generic masculine is more acceptable to refer to mixed groups. In the sentence comprehension task, which inquires about automatic processes and implicit representations, the non-binary forms consistently elicited a reference to mixed groups. Furthermore, the response times indicated that these morphological variants do not entail a higher processing cost than the generic masculine.

The Adoption and Use of the Word ἘΚΚΛΗΣΊΑ in the Early Christ-Movement

This article engages with two recent monographs and three shorter publications to offer a fresh approach to the origin and some aspects of the use of the word ἐκκλησία in the Christ-movement of the first century ce. It argues that the word was first used as a collective designation by mixed groups of Greek-speaking Judean and non-Judean Christ-followers who were persecuted by Paul. Their intimate table-fellowship (especially of the one loaf and one cup of the Lord’s Supper) was regarded as involving or risking idolatry and thus imperilling the ethnic integrity of the Judean people. These Christ-followers adopted the word ἐκκλησία from instances in the Septuagint where it meant not ‘assembly’ but ‘multitude’ or ‘group’, most importantly of all in 1 Sam. 19.20. As Paul founded new communities in the cities of the Eastern Mediterranean that were recognisably similar to Greco-Roman voluntary associations, the word acquired new connotations that reverberated with the role of ἐκκλησίαι as civic voting assemblies in the Greek cities. Paul’s groups were not anti-Roman, nor did he believe that the Christ-movement would replace ethnic Israel, but rather that the two would co-exist until the End. The Pauline view on this matter finds theological endorsement in a 2015 document from the Vatican’s Commission for Religious Relations with Jews.
