Holocene peat Hg anomalies
No full textThis project examines the major explosive volcanic eruptions recorded in peat. Hg data from three peat profiles, the Hongyuan and Dangxiong peat from the Tibetan Plateau and the Pinet peat record from France, were synthesized here to support our conclusions. All the Hg data and the MATLAB script are prepared for the manuscript entitled "Tibetan peat saw Holocene global major explosive volcanic eruptions".Corresponding author: Haijun PENG, [email protected].</p
Author Response to “Pushing the Limits of Strength Training”
No full textPhotothermal catalytic dry reforming of methane with CO₂ has emerged as a promising yet nascent strategy for mitigating greenhouse gas emissions and enabling clean energy conversion. However, achieving optimal performance requires advances in both catalyst design and mechanistic understanding. Herein, we adopted a double-emulsion-guided micelle assembly strategy to synthesize asymmetric supports (AMONs and AMOMs), featuring unidirectional open/closed pore channels. This distinctive architecture enabled the formation of an asymmetric catalyst configuration through ethylene glycol-assisted selective confinement of Ni nanoparticles at the open-pore termini. Compared to conventional symmetric catalysts, the optimized 5% Ni AMONs EG and 5% Ni AMOMs EG exhibited higher specific surface areas and improved metal dispersion, resulting in an abundance of active sites. Moreover, the asymmetric design strengthened the built-in electric fields, directing more photogenerated hot carriers and localized thermal energy toward reactant activation. Consequently, 5% Ni AMOMs EG achieved a remarkable H₂ production rate of 2314.2 mmol g⁻¹ h⁻¹ and sustained H₂ yields over 50 hours, outperforming symmetric counterparts and even some reported noble metal-based catalysts. This work offers a smart photothermal catalyst candidate and elucidates its structure–performance relationship, advancing photothermal catalytic technology for solar fuel production.Cheng Sang, Weiyi Xu, Kang Xue, Yajie Zou, Shuli Li, Shengjie Han, Haijun Chen, Hongqi Sun, Shaobin Wang, and Jinqiang Zhan
Training online faculty: a phenomenology study
No full textLiterature on training faculty to teach online still dwells on the issues explored a
decade ago. To make a substantial move in this area, it is necessary to re-evaluate the
essence of training in the context of producing qualified online faculty to teach quality
online courses. Employing a phenomenological approach, this study examines seven
online faculty’s lived training experiences and observed that there existed incidental
factors that could affect the quality of training. Further data analysis indicated that it
was the different levels of understandings of “training” between different parties that
led to variations in the quality of training. “There is a whole [training] world that’s
going on out there … I’m just not interested… because that’s not my world,” said one
research participant. Therefore, different parties involved in training online faculty
should look at training from a systems approach and view training as an opportunity
(1) to transfer knowledge and skills necessary for conducting quality online
instruction; (2) to remove barriers preventing faculty from teaching online; and (3) to
transform traditional faculty members into highly qualified online faculty
Understanding online reading through the eyes of first and second language readers: an exploratory study
No full textUtilizing eye-tracking technology and focusing on the “rapid”, “purposeful” and “comprehending” attributes of fluent reading, this study investigated first language (L1) and second language (L2) readers’ online reading patterns and comprehension. Eye movement data from nine L1 readers and nine L2 readers were collected, analyzed and compared. Post-experiment interviews were conducted to obtain demographic and background information. The results indicate that L1 and L2 readers are heterogeneous when language proficiency is considered but they are homogeneous in many other aspects when the focus is on their online reading patterns and comprehension. While L1 readers read much faster than L2 readers, their attention distribution and performance on reading comprehension test are similar to L2 readers’. This study concludes that the essential online reading competency factors are similar in L1 and L2’s online reading when the “rapid”, “purposeful” and “comprehending” attributes of fluent reading are under investigation. When the core vocabulary of a language is mastered, it is metacognitive reading skills that play a major role in fluent reading in the context of new literacy
Rethinking distance learning activities: a comparison of transactional distance theory and activity theory
No full textDespite its invaluable guidance to distance education development, transactional distance (TD) theory is not seamlessly synchronised with current field practice and lacks a social component. After it has provided over 30 years of guidance, there is now a need to re-appraise TD’s propositions about distance learning activities. The social–cultural aspects of the distance learner need to be highlighted because social learning is prominent in today’s practice. To address this concern, we compared TD with a social science theory – cultural–historical activity theory. This cultural–historical activity theory provides a different lens for us to explore distance learning activities – a social lens. We compare the major concepts of the two theories and illustrate some areas of compatibility. We explore the contradictions that arise from the collision of these two theories and recommend future directions for research
