Dataset for "Short-Form Videos Degrade Our Capacity to Retain Intentions: Effect of Context Switching On Prospective Memory"
No full textSocial media platforms use short, highly engaging videos to catch users’ attention. While the short-form video feeds popularized by TikTok are rapidly spreading to other platforms, we do not yet understand their impact on cognitive functions. We conducted a between-subjects experiment ( = 60) investigating the impact of engaging with TikTok, Twitter, and YouTube while performing a Prospective Memory task (i.e., executing a previously planned action). The study required participants to remember intentions over interruptions. We found that the TikTok condition significantly degraded the users’ performance in this task. As none of the other conditions (Twitter, YouTube, no activity) had a similar effect, our results indicate that the combination of short videos and rapid context-switching impairs intention recall and execution. We contribute a quantified understanding of the effect of social media feed format on Prospective Memory and outline consequences for media technology designers not to harm the users’ memory and wellbeing.

Near-infrared cathodoluminescence of Xe2 excimers in dense gaseous mixtures
No full textWe report new spectroscopic measurements of the near-infrared uorescence
band of electron-beam excited Xe2 excimers as a function of the gas density in
several gaseous mixtures of different Xe concentrations at room temperature. We
have used He, Ar, and N2 as buffer gases, with the Xe concentrations in the
mixtures ranging from approximately 8% up to 80%. The investigated density
range extends up to 10 times the density Nig of the ideal gas at standard
temperature and pressure (Nig ≈ 2.5 × 1025m−3). In all mixtures, we have
observed that the wavelength of the centroid of the infrared excimer band is
shifted toward longer wavelengths as the gas density is increased, in a manner
similar to what was originally observed in pure Xe gas and an Ar–Xe mixture. The
strength of the redshift depends on the Xe concentrations in the mixture and the
nature of the buffer gas and is very well rationalized by taking into account both
the classical dielectric screening effect due to the gaseous environment and the
density-dependent quantum shift of the energy of the optically active electron in
the Xe2 molecule, provided that the contributions of the two gaseous species in
the mixture are weighted by applying the laws of ideal gaseous mixtures

Supplementation of Probiotics in Pregnant Women Targeting Group B Streptococcus Colonization: A Systematic Review and Meta-Analysis
No full textThis systematic review and meta-analysis aimed to determine if probiotic supplementation in pregnancy reduced maternal Group B streptococcus (GBS) recto-vaginal colonization in pregnant women at 35–37 weeks of gestation. Electronic databases (i.e., PubMed, MEDLINE, ClinicalTrials.gov, ScienceDirect, and the Cochrane Library) were searched from inception up to February 2022. We included RCTs assessing the effects of probiotic supplementation in pregnancy on GBS recto-vaginal colonization. The primary outcome was GBS-positive recto-vaginal cultures performed at 35–37 weeks of gestation. Secondarily, we evaluated obstetric and short-term neonatal outcomes. A total of 132 publications were identified; 9 full-length articles were reviewed to finally include 5 studies. Probiotic supplementation reduced vaginal GBS colonization: the GBS positive culture rate was estimated at 31.9% (96/301) in the intervention group compared to 38.6% (109/282) in the control group (OR = 0.62, 95% CI 0.40–0.94, I2 4.8%, p = 0.38). The treatment started after 30 weeks of gestation and was more effective in reducing GBS colonization (OR 0.41, 95% CI 0.21–0.78, I2 0%, p = 0.55). Probiotic administration during pregnancy, namely in the third trimester, was associated with a reduced GBS recto-vaginal colonization at 35–37 weeks and a safe perinatal profile. Whether this new strategy could reduce the exposition of pregnant women to significant doses of antibiotics in labor needs to be evaluated in other trials
Dual-tasking effects on static and dynamic postural balance performance: a comparison between endurance and team sport athletes
No full textIn sports, postural balance control has been demonstrated to be one of the limiting factors of performance and a necessary component to achieve any sport technique. Team players (TP) must process and react to multiple external stimuli while executing at the same time the skills of the game. By contrast, endurance athletes (END) must perform the same gesture repetitively without a concurrent coordination of continuous stimuli-related actions. However, END are used to facilitate their physical performance by adopting cognitive strategies while performing their sport gesture. Therefore, we aimed to investigate static and dynamic balance performance in these two types of athletes, both in single and dual-task conditions. Nineteen END and sixteen TP underwent a static and a dynamic balance assessment on a dynamometric platform and an instrumented oscillating board, respectively. Among TP static but not dynamic postural balance performance was negatively affected by dual-tasking considering the area of the confidence ellipse (p < 0.001; d = 0.52) and the sway path mean speed (p < 0.001; d = 0.93). Conversely, END unaltered static balance performance but showed an overall improvement in the dynamic one when dual-tasking occurred. The limited human processing capacity accounted the worsening of the cognitive performance in both TP (p < 0.05; d = 0.22) and END (p < 0.001; d = 0.37). Although TP are more used coping dual tasking, the better performance of END could be accounted for by the employment of the external attentive focus (i.e. counting backward aloud) that called into play a strategy close to those adopted during training and competitions. These surprising results should be considered when driving and developing new trainings for team players in dual-tasking conditions
Didattica e ricerca. L’esperienza del Laboratorio aragonese e sforzesco
No full textIn the workshop on Diplomatic correspondences in the Italian Renaissance, directed in January-May 2018 by Francesco Storti and Francesco Senatore in the Istituto italiano per gli studi filosofici of Naples, 12 undergraduate and graduate students learned to read and trascribe italian diplomatic dispatches of the 15th cent., producing a specimen of scientific edition. In the opinion of the author, such activities and similar ones are very useful for future school teachers and scholars and they could be introduced in the university and pHD courses of history. Students of humanistic sciences should have concrete contacts with the historical research on primary sources. On the other hand, editing of historical sources could become a marginal activity because it is not enough appreciated in the current research evaluation processes.
