Phase Transformation-Induced Intimate Ag Deposition In Ag-Tio2 Hybrids For Enhanced Photocatalytic Antibacterial Performance, Nhu Nang Vu, Bich Van Tran, Safa Ladhari, Alireza Saidi, Amine Aymen Assadi, Phuong Nguyen-Tri

Études primaires

The current work presents a novel approach for synthesizing antibacterial Ag-TiO₂ hybrid nanoparticles (NPs) by leveraging the phase transformation of dual-phase TiO₂ NPs derived from peroxo-titanium complex to promote the Ag photodeposition. The UV-driven Ag deposition initiates transformation from anatase to rutile in the lattice of TiO₂ NPs, enhancing their crystallinity while enabling intimate deposition of AgNPs on the TiO₂ surface through chemically bonded interfaces. The inherent rutile phase and doped Ag species resulting from the Ag deposition promote the phase transformation as nucleation sites, while the Ag concentration also plays a crucial role in regulating …

Vocational Training And Occupational Health: An Ergonomics Approach To Gender And Disabilities For Social Sustainability, Myriam Bérubé, Céline Chatigny, Marie Laberge

Études primaires

The Work-Oriented Training Path (WOTP) in Quebec, Canada, is a dual vocational training program that offers students with learning difficulties supervised traineeships. Teachers play a pivotal role in managing students' occupational health and safety (OHS), yet must do so under tight time constraints, limited institutional guidance and highly diverse student profiles. Building on an activity-centered ergonomics and capabilities framework, this multiple-case study explores how gender, disabilities, and work determinants shape OHS management within the WOTP, emphasizing their implications for social sustainability. Twenty-seven semi-structured interviews were conducted with 15 WOTP teachers; 497 narrated anecdotes, which are units of speech when teachers' …

Interactive Effects Of Intrasexual Competitiveness, Same-Sex Competition, And Physical Attractiveness On Temporal Discounting, Jose C. Yong, Indra Alam Syah Aziz, Hualin Xiao, Norman P. Li

Research Collection School of Social Sciences

Studies have shown that men discount the future and prefer immediate-but-smaller over delayed-but-larger rewards when exposed to mating opportunities (e.g., attractive opposite-sex targets) or threats (e.g., same-sex competition) whereas women's discounting in response to similar cues appears mixed, suggesting that mating-motivated discounting is primarily a male phenomenon. Importantly, this line of research has not yet examined the role of individual difference variables as well as how the attractiveness of potential mates and perceptions of competition jointly influence discounting rates. We conducted a novel test of the effect of trait intrasexual competitiveness (ISC) using dating profiles varying on target attractiveness and …

Research Collection School of Social Sciences

The increasing prevalence of cyberbullying victimization has become a commonplace issue globally. Although research has explored various predictors and consequences of cyberbullying victimization, most focus on a narrow range of variables or contexts, highlighting the need to comprehensively review and synthesize the wealth of empirical findings. We conducted a systematic review of meta-analyses on cyberbullying victimization, incorporating 56 meta-analyses and 296 effect sizes (sample size range 421–1,136,080, sample size median 53,183; searched via EBSCOhost ERIC, EBSCOhost PsycInfo, PubMed, Scopus, Web of Science, 13 cyberbullying-related journals, Google Scholar and ProQuest Dissertations and Theses) to address the following critical questions: (1) What …

Learning By Teaching With Deliberate Errors Promotes Argumentative Reasoning, Sarah Shi Hui Wong

Research Collection School of Social Sciences

Reasoning and arguing well lies at the core of thinking and constructing knowledge about complex, controversial issues. Leveraging the techniques of learning by teaching and deliberate erring, the present study developed and tested a novel intervention—learning by misteaching—to boost argumentative reasoning. University students (N = 208) were trained on argumentation strategies and studied a dual-position argumentative text on a controversial topic using one of three learning methods: notetaking, correct teaching, or misteaching. The notetaking group prepared to be tested and wrote study notes while generating good arguments about the topic, whereas both teaching groups prepared to teach and wrote a …

Aniela (2025), Blanca Vadillo Sánchez

Grado en Diseño de Moda

Hay cosas que no se dicen, pero permanecen. Una prenda, a veces, es eso: una forma de quedarse, de insistir sin imponerse, de sostener algo que aún no tiene nombre. Este proyecto no propone una respuesta, sino una serie de aproximaciones a través del diseño, el cuerpo y el tiempo. Se parte de una pregunta simple pero insistente: ¿qué significa permanecer cuando todo parece pensado para desaparecer? En un contexto marcado por la velocidad del consumo, por el ritmo acelerado de una industria que produce sin pausa y olvida con rapidez, Aniela propone otra temporalidad. Una más atenta, más situada. …
