The recent literature highlights the importance of implementing ad hoc media literacy initiatives to counter sexist stereotypical representations in social media, particularly within the political field. To this end, the present study focuses on false and misleading contents (information disorders) about female politicians, since they can reflect gender stereotypes, portraying women as unfit for political roles. Thus, our exploratory study aims to analyze the stereotype content of information disorders targeting Italian female politicians, following classic models of stereotype content. Furthermore, it seeks to explore the role played by the type of information disorder and the political orientation of the targeted leaders. A database of 120 information disorders have been collected, codified, and analyzed. The results highlight that information disorders predominantly target the dimension of communion. Focusing on the types of information disorders, fabricated and misleading content appears to be associated with the professional and private life domains, primarily conveying communion-based stereotypical representations of politicians. Satirical and parodic contents, on the other hand, were associated with the esthetic domain, conveying agency-based stereotypical representations, with a particular focus on politicians’ physical competence. Regarding political orientation, a “Stereotyping from my eyes” effect was observed: communion-based stereotypical content prevails in information disorders targeting conservative leaders, while progressive leaders are stereotyped concerning the agency dimension. This effect may reveal a difference between conservative and progressive audiences in their adherence to traditional gender roles.

A solid phase microextraction (SPME) method coupled with liquid chromatography (LC) and fluorescence/ultraviolet-diode array detection was developed for the simultaneous determination of quercetin and trans-resveratrol. The chromatographic, detection, and SPME extraction/desorption conditions were systematically optimized. The performance of four commercial SPME fibers—polyacrylate (PA), polyethylene glycol (PEG), polydimethylsiloxane (PDMS), and polydimethylsiloxane-divinylbenzene (PDMS-DVB)—was evaluated and compared with a homemade polydopamine (PDA)-coated fiber. While all of the fibers successfully extracted the target analytes, their efficiencies varied significantly. The PA, PEG, and PDA fibers demonstrated superior performance, exhibiting wide linearity ranges (0.03–1 µg/mL (PA and PEG) and 0.06–1 µg/mL (PDA) for quercetin, 0.01–1 µg/mL for trans-resveratrol); high sensitivity (LODs of 0.01 µg/mL (PA and PEG) and 0.02 µg/mL (PDA) for quercetin, 0.003 µg/mL for trans-resveratrol); and excellent precision. Among these, the polyacrylate coating delivered the best analytical performance and was selected for further application. The optimized method was applied to analyze winemaking by-products (seeds, skins, and stalks) using SPME on ethanol-macerated extracts subjected to brief ultrasonication. Quercetin and trans-resveratrol were quantified in pomace extracts at concentrations of 104.3 ± 8.2 µg/g and 38.5 ± 4.1 µg/g, respectively. Recovery experiments confirmed the method’s accuracy, with recoveries of 99.1 ± 7.4% for quercetin and 98.5 ± 9.8% for trans-resveratrol. This study establishes a reliable, sensitive, and efficient approach for the determination of these bioactive compounds in complex matrices, with potential applications in the food and pharmaceutical industries.

Human communication is multimodal, with verbal and non-verbal cues such as eye gaze and vocal feedback being crucial for managing interactions. While much research has focused on eye gaze and turn alternation, few studies explore its relationship with turn-regulating vocal feedback. This study investigates this interplay during a Tangram game in Italian under two visibility conditions: face-to-face and separated by a screen. The results show that feedback producers rarely look at receivers, while receivers more frequently look at producers, suggesting that they might be eliciting vocal feedback. Without visual contact, gaze shifts decrease and vocal feedback increases. Interestingly, when visual contact is absent, gaze directed towards where the addressee is sitting does not coincide with vocal feedback, raising questions about what prompts this gaze.
