Research has shown learning advantages for self-controlled practice contexts relative to yoked (i.e., experimenter-imposed) contexts; yet, explanations for this phenomenon remain relatively untested. We examined, via path analysis, whether self-efficacy and intrinsic motivation are important constructs for explaining self-controlled learning benefits. The path model was created using theory-based and empirically supported relationships to examine causal links between these psychological constructs and physical performance. We hypothesised that self-efficacy and intrinsic motivation would have greater predictive power for learning under self-controlled compared to yoked conditions. Participants learned double-mini trampoline progressions, and measures of physical performance, self-efficacy and intrinsic motivation were collected over two practice days and a delayed retention day. The self-controlled group (M = 2.04, SD = .98) completed significantly more skill progressions in retention than their yoked counterparts (M = 1.3, SD = .65). The path model displayed adequate fit, and similar significant path coefficients were found for both groups wherein each variable was predominantly predicted by its preceding time point (e.g., self-efficacy time 1 predicts self-efficacy time 2). Interestingly, the model was not moderated by group; thus, failing to support the hypothesis that self-efficacy and intrinsic motivation have greater predictive power for learning under self-controlled relative to yoked conditions.

The aim of the study was to review the scientific literature on educational interventions to promote positive attitudes towards science in middle school students. Due to the decline in positive attitudes towards science observed in this critical age group of students and the implementation of training programmes aimed at changing this situation, we sought to identify components of training proposals that have received attention from researchers. This paper presents a scoping review of 37 papers published in English and Spanish over the last 10 years.

This study presents a revolutionary understanding of how value-based leadership enhances the intrinsic work motivation of Chinese university faculty. A novel serial mediation model is introduced, highlighting the interplay between growth mindset and teaching self-efficacy in transmitting the impact of leadership to increased intrinsic motivation. Utilizing a comprehensive sample of 394 faculty members from across China, advanced SmartPLS 3.

Tumor hypoxia is a critical driver of cancer progression, metastasis, and therapy resistance, posing significant challenges in effective cancer treatment. Hypoxia-activable prodrugs offer a promising strategy to target tumors in low-oxygen conditions, but their efficacy is often hindered by intrinsic properties and extrinsic cues. In this study, we developed a dual-prodrug nanoassembly system (CPPA) composed of a hypoxia-triggerable camptothecin (CPT)-based dimeric prodrug (CP) and a lipid-conjugated STAT3 antisense oligonucleotide (ASO) prodrug (PA), aiming to enhance tumor-targeted chemotherapy and overcome the immune evasion within the tumor microenvironment.

Previous research has highlighted positive associations between physical education (PE) teachers' transformational leadership and their adolescent students' intentions to be active. However, no prior investigators have addressed mediating variables of students' motor self-efficacy and enjoyment. Our aim in this study was to re-analyze the relationships between teachers' transformational leadership style and PE students' intentions to be active, while also examining the roles of motor self-efficacy and enjoyment as potential mediators in these relationships.

The development of self-elastic sponges with enhanced hemostatic and antibacterial properties to treat noncompressible hemorrhage and facilitate wound healing remains challenging. Herein, we prepared a chitosan sponge reinforced with lauric acid-modified quaternized chitosan (LQC) and attapulgite, features a porous structure, high self-elasticity, and rapid shape recovery. The incorporation of LQC conferred the sponge with an enhanced capacity to promote the adhesion, aggregation, and activation of blood cells, and resistance to infection by Staphylococcus aureus, Escherichia coli, and Methicillin-resistant Staphylococcus aureus; the incorporation of attapulgite enhanced the hydrophilicity and mechanical strength of the sponge, and its ability to activate the intrinsic and extrinsic coagulation pathways.
