Coal-derived char has shown improving the geotechnical performance of cement-stabilized soils. This study aimed to assess the effects of coal char on the hydraulic and durability characteristics of a soil mixture composed of equal sodium bentonite and sand, stabilized with 20% cement. The addition of coal char enhanced both hydraulic and durability properties of the cement-stabilized soil. The inclusion of coal char in cement-stabilized soil further reduced the saturated hydraulic conductivity (Ksat) up to 38%, suggesting decreased water infiltration and greater soil compaction. The soil freezing characteristic curve (SFCC) showed that adding char to cement-stabilized soil samples retained more unfrozen water after 12 freeze-thaw (FT) cycles, which can reduce frost heave for better freeze-thaw resistance. Soil water characteristic curve (SWCC) results demonstrated that char addition improved moisture retention at low suction levels, which could prolong hydration, reduce shrinkage & cracking, and improve drought resilience in arid environments.
Structural, mechanical, and optical properties of the Ba3BiX3 (X = I, Br, Cl, and F) compounds were studied in terms of first-principles density functional theory (DFT) calculations within generalized gradient approximation-Perdew-Burke-Ernzerhof (GGA-PBE) assumptions using Quantum ESPRESSO. Structural investigation establishes the cubic nature of the Ba3BiX3 (X = I, Br, Cl, and F) compounds that have stable geometries, and the lattice parameters reduce sequentially with halogen replacement. Investigation of the electronic properties using the electronic property analysis shows that Ba3BiX3 (X = I, Br, Cl, and F) compounds belong to the category of direct bandgap, and the bandgap decreases systematically with heavier halogens, whereas the effect of spin-orbit coupling is dominant on the electronic structure. Ba3BiF3 has the highest bandgap and smallest effective masses of all of them, meaning the best optoelectronic prospects. The dynamical stability of the compounds is confirmed by phonon dispersion analysis and vibrational frequencies. The compounds have stiffer, harder, and more thermally stable structures as determined by both mechanical and thermodynamic analyses. Optical investigations of Ba3BiX3 (X = I, Br, Cl, and F) compounds provide tunable dielectric, highly absorbing response, and refractive index variation, with the best visible response in Ba3BiI3 and the best UV performance in Ba3BiF3.
Research on corporate social responsibility (CSR) has increasingly noted the danger of corporate hypocrisy, a misalignment between a firm's CSR claims and actions, yet little is known about its internal consequences. Drawing on social learning theory, this study explores how and when corporate hypocrisy cascades down through an organization to foster hypocrisy among employees. We employed a multi-level, three-tier data collection across 32 Chinese companies to test our model. The findings show that corporate hypocrisy at the organizational level does indeed trickle down. Specifically, it promotes team leader hypocrisy which, in turn, leads to team member hypocrisy. Moreover, this trickle-down effect is contingent on value alignment. It is strengthened when team leaders exhibit person-organization (PO) fit and team members exhibit person-supervisor (PS) fit. We discuss the theoretical and practical implications of the findings on the trickle-down effect of corporate hypocrisy.
The research-practice gap (the gap) in HRD remains a significant challenge, hindering the application of academic research to practice and the integration of workplace challenges into research efforts. It is critical for HRD research to address the gap to develop evidence-based solutions for learning and organizational performance. The purpose of this study was to explore how HRD scholars and scholar-practitioners define, motivate, address barriers to, and recommend strategies for bridging the gap in HRD. Building on the study by Moore and Cho (2024) from the perspective of HRD practitioners, we investigated the perspectives of HRD scholars and scholar-practitioners to examine whether there are any critical differences in their perspectives through 29 interviews. In a thematic analysis, we identified four key themes: defining the gap, motivations, barriers, and strategies for bridging the gap. Participants emphasized the need for participatory action research, the co-creation of research agendas, and practitioner engagement from the early stages of research to enhance the relevance and applicability of the findings. A surprising study finding was the influential role of HRD scholar-practitioners, who serve as translators between academic research and workplace applications, leveraging their dual roles to co-create usable knowledge. We provide actionable recommendations for narrowing the gap, stressing the role of HRD in diverse organizations by fostering collaboration and integrating academic rigor with practical applications.
Let $\sigma$ and $\tau$ be patterns of length three; that is $\sigma, \tau \in \{123,132,213,231,312,321\}$. In this paper, we enumerate the set of cyclic permutations in $\mathcal{S}_n$ that avoid $\sigma$ in their one-line notation and another pattern $\tau$ in their cycle notation.
