Your Silence Speaks Loudly: A ventriloquial approach to corporate silence about commitment in argumentative polylogues López de Pedro, José María Corporate social responsibility research often emphasizes the commissive effects of corporate discourse,ignoring silence or considering it a deliberate strategy to evade stakeholder pressure. From this perspective,only corporate discourse commits, and silence is the absence of discourse. This paper challenges thisapproach. Drawing on ventriloquial theory (Cooren, 2010) and the notion of metaventriloquism (Castor,2020), this paper develops the concept of corporate commissive silence (CCS) to theorize how corporatesilence on commitments operates as a malleable sign and a contested semiotic space. Specifically, it interpretsCCS as an absence of message that different agents identify, attribute to a company, and imbue withmeaning to promote their own opinions about what animates and/or should animate that company. As thisconcept highlights, not only words but also silence can generate commissive dynamics for corporations. Thecommunicative force of this type of silence does not depend on corporate intentionality, but rather on theoperations of appropriation and reinterpretation executed by other agents. To illustrate the utility of thisconcept, I describe several metaventriloquial practices executed by various agents in a recent controversysurrounding Disney’s silence on Florida’s HB 1557 law.

Muscle failure and risk of adverse outcomes in older adults: a derivation and multicohort validation study

Muscle failure and risk of adverse outcomes in older adults: a derivation and multicohort validation study Coelho-Junior, Helio José; Álvarez Bustos, Alejandro; Rodríguez-Sánchez, Isabel; Landi, Francesco; Marzetti, Emanuele Summary Background Sarcopenia is inconsistently defined, and its definition might not adequately capture muscle failure, underlying disability, and other adverse outcomes in older adults. We aimed to develop and validate an evidence-based, outcome-driven model of muscle failure. Methods In this derivation and multicohort validation study, we analysed data from the SPRINTT randomised controlled trial (1519 participants; mean age 78·9 years [SD 5·8]; 431 [28·4%] men, 1088 (71·6%) women) and validated findings in five independent cohorts (ilSIRENTE, NHANES, HRS, ELSA, and CHARLS). Neuromuscular domains including appendicular lean mass, muscle strength and power, mobility, and physical activity were assessed. Principal component analysis identified clusters of measures, which were tested for associations with disability in mobility and disability in activities of daily living, hospitalisation, and mortality using adjusted regression models. Predictive performance was evaluated with receiver operating characteristic curves. Area under the curve (AUC) values were defined as acceptable (0·7–0·8), excellent (0·8–0·9), or outstanding (>0·9). Findings We identified two major muscle failure indexes: mobility (short-distance walking speed, 400 m walk) and physical activity (step counts, time spent standing, stepping, and sitting). In SPRINTT, the mobility model strongly predicted disability (AUC 0·721, 95% CI 0·698–0·795; p<0·0001), whereas the physical activity model was more closely associated with hospitalisation (0·646, 0·570–0·731; p=0·00040) and mortality (0·746, 0·612–0·926; p=0·0020). Combined models including mobility, handgrip strength, appendicular lean mass, and absolute muscle power improved prediction of mortality (0·746, 0·549–0·955; p=0·0076). External validation confirmed acceptable-to-strong discrimination for disability outcomes across cohorts (AUCs 0·7–0·9), while associations with hospitalisation and mortality were weaker and inconsistent (0·4–0·9). Compared with consensus-based sarcopenia definitions, the evidence-based model seemed to show better predictive ability for disability. Interpretation Distinct mobility measures provide a robust framework for identifying muscle failure and predicting disability in older adults. Continuous activity monitoring might improve prediction of hospitalisation and mortality. This outcome-driven approach supports refinement of sarcopenia assessment and its implementation in clinical practice.

Who decides? Intergenerational perception of adolescents' personal care products purchase and consumption. Irarrázaval, José; Feijoó Fernández, Beatriz; Negredo, Samuel This study explores intergenerational differences in theperception of adolescents' (ages 12–17) use of personalcare products and related purchasing decisions. An on-line survey of 1088 parent–child dyads (n = 2176) wasconducted, and paired samples t-tests were used. Resultsshow minors report higher usage—especially of gym andfitness items—than parents acknowledge. Adolescentsalso perceive more parental supervision than parents re-port. Parents set stricter age limits for purchasing itemslike makeup and supplements and express greater concernover risks. These findings reveal perception gaps that mayinform educational and regulatory approaches to adoles-cent consumption.

Dilemmas Faced by Micro-influencers in Commercial Collaborations: Ethical Responsibility and Personal Gain

Dilemmas Faced by Micro-influencers in Commercial Collaborations: Ethical Responsibility and Personal Gain Marchán Sanz, Clara; Fernández Gómez, Erika; Feijoó Fernández, Beatriz Influencer marketing continues to expand, intensifying debates about compliance with advertising regulations and the distribution of responsibility among influencers, brands, and other stakeholders. This qualitative study draws on 30 in-depth interviews with micro-influencers in Spain to examine how they interpret and manage legal requirements and ethical considerations in the context of commercial collaborations. The findings indicate a high level of awareness of disclosure obligations, with most participants reporting regular identification of sponsored content. While interviewees generally attribute primary responsibility for product-related information to brands, they also acknowledge shared accountability and describe practices aimed at ensuring accuracy and maintaining credibility. Although participants recognize significant pressure to increase follower numbers, they largely reject the practice of purchasing followers. Instead, they emphasize authenticity, thematic coherence, and trust as central to sustaining their professional legitimacy. Overall, micro-influencers conceptualize ethical responsibility less as strict adherence to formal rules and more as an ongoing communicative practice oriented toward credibility, audience expectations, and long-term professional sustainability.
