The current study explored the association between communication deviance (CD) in a cohort of mothers (n= 287) at 32 weeks gestation and maternal sensitivity (MS) to the infant’s cues during playful interaction at 6 months into the post-natal period. CD during the antenatal period was a significant predictor of lower MS during play (B= -0.385; p< .001). The relationship remained significant when maternal age, IQ and index of multiple deprivation (IMD) were accounted for. Further analyses revealed that CD was a significant predictor of MS in the context of infant distress (B= -0.514; p< .001) but less so in the context of non-distress (B= -0.311; p< .01). Results suggest that CD may index a complex cross-modal process affecting mother-child interactions.

The Relationship

The work performed allowed us to determine the correlation of giftedness, level of intelligence, academic success and conscious self-regulation in children of young adolescents. Diagnostics was carried out using the “Creative Field” method (D. B. Bogoyavlenskaya), the “Progressive Matrices” test (J. Raven) and the rapid method «Style of Self-regulation of Children Behavior» SSCB-M1 (V. I. Morosanova). The results were obtained as part of a longitudinal study from primary school to adolescence. Statistical analysis is represented by correlation analysis and the method of constructing regularized networks of patial correlations glasso using the language R. Giftedness is understood by us as the ability to develop activities on our own initiative. Mathematical analysis reveals an indirect connection between giftedness and a cluster of conscious self-regulation through an intelligence index. The negative sign of the connection between intelligence and the “planning” scale is explained by the characteristics of the age under study: the breadth of interests, the situation of choice and the criticality of children with a high level of intelligence, which leads to lower grades.

Over Time

A large public tier-1 university hosted an autonomous vehicle on campus for a 12-week demonstration. Throughout the deployment, the vehicle was operated autonomously and used 5 safety operators from the student population to take over shuttle operations, as necessary. Daily and weekly surveys as well as pre-and post-study interviews were used to investigate how operators’ trust developed and changed over time as well as the relationship between trust and operational issues that varied in severity. Results revealed that there was not a significant relationship between trust and severity of operational issues. Trust levels appeared to remain relatively consistent before, during and after the deployment.

BackgroundPigs are frequently colonised with Salmonella enterica, and this constitutes a major risk for human salmonellosis. The infection can be assessed by the serological response of pigs to S enterica. A longitudinal study was undertaken on-farm to correctly describe this serological response and investigate factors associated with age at Salmonella seroconversion.MethodsThree pig farms and in each farm three successive batches were considered. Per batch, 40 piglets were selected at random from 10 sows (four piglets per sow). Blood was sampled from sows one week after farrowing and from piglets at weeks 1, 6, 10, 14, 18 and 22 and at the slaughterhouse. Salmonella antibodies were detected in serum using a commercial ELISA test. Factors related to farm characteristics, batch management system, porcine reproductive and respiratory syndrome infection, and sows’ Salmonella serological status were recorded to assess their effect on age at seroconversion.ResultsAt week 1 after farrowing, 96.5 per cent of the sows had antibodies against Salmonella. The serological results of piglets at weeks 1 and 6 only were positively correlated with those of the sows. The average age at Salmonella seroconversion was 137±2.2 days (confidence interval at 95 per cent). The first seroconversions occurred from weeks 10 to 14, but most of the pigs (54.6 per cent) were seropositive at the end of the fattening period, with variations between farms and batches (28.9–75.7 per cent). Herd/farm was significantly associated with age at seroconversion.ConclusionThis longitudinal study allowed the authors to follow precisely the evolution of Salmonella seroconversion from maternity to slaughterhouse and confirm the relationship between the seroconversion of sows and serology of their piglets. Moreover, factors related to farm practices and management as a whole are more influential than individual factors (at the pig level) on age at Salmonella seroconversion.
