Strengthened Voice Through Pedagogical Partnerships: A Story of Transformational Learning
No full textParticipating in the Pedagogical Partnership Project through BranchED (Branch Alliance for Education Diversity) deepened our understanding of BIPOC (Black, Indigenous, People of Color) students’ and faculty members’ experiences in the higher education setting. This concept of a partnership between a faculty member and the student was tempting for its novelty (at least to us) and for its purpose, which focuses on supporting students’ success (Cook-Sather, 2018; Healey et al., 2016). In fact, a research study conducted by Cook-Sather (2018) suggests that participating in pedagogical partnerships “(1) fosters important affective experiences in relation to all faculty and to fellow students, (2) informs students’ academic engagement in their own classes, and (3) contributes to students’ sense of their evolution as active agents in their own and others’ development” (p. 4).https://opus.govst.edu/fac/1305/thumbnail.jp
A Visual Definition of Caregiving: Caring About, Caring For, and the Feminization of Care
No full textOver the past decade, stories about financial, physical, and interpersonal strains facing unpaid family caregivers have steadily increased (Eisenstadt 2014; McSweeney-Feld 2013; Rieder 2012; Tunajeck 2010). Such narratives are becoming more common as the caregiver to care receiver ratio grows increasingly lopsided (McSweeney-Feld 2013). Pro-caregiving advocates championing policy changes for unpaid caregivers have progressively begun to use the term “caregiving crisis” to describe negative conditions impacting individuals who care for others, including, but not limited to chronic illness and financial strain. Of observable concern, is that the primary role of caregiving tends to fall on women who are implicated in a complex history of caregiving rhetoric that centers on motherhood and lack of agency. This complex history has been further exacerbated by the 2020 Covid pandemic, which has disproportionately impacted women in general (Olen 2021; Fox, 2021; Gogoi 2020), and mothers in particular (Grose, 2021; Gross 2021; Leonhardt 2020).https://opus.govst.edu/fac/1192/thumbnail.jp
Biodegradation Method of Soil Microplastics Based on Enzymatic Engineering
No full textMicroplastics, which refer to small plastic particles with a diameter less than 5 millimeters, have gained global attention due to their accumulation in soil and waterways, potentially harming the health of wildlife and ecosystems. Enzyme engineering-based remediation techniques offer a promising, cost-effective and environmentally-friendly approach for cleaning microplastics from soil. This article provides an overview of enzyme engineering-based bioremediation strategies for addressing soil microplastic pollution, highlighting the factors that may impact their efficacy, in the pursuit of identifying the optimal approach for remedying this issue.https://opus.govst.edu/fac/1189/thumbnail.jp
Effects of Perfluorinated Compounds Homologues on Chemical Property, Microbial Composition, Richness and Diversity of Urban Forest Soil
No full textPerfluorinated compounds (PFCs), as an important class of new persistent organic pollutants, are widely distributed in the environment. Yet the effects of different types and concentrations of PFCs on soil microbial community in urban forest ecosystems are remain uncertain. Here, two typical PFCs, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), were selected to carry out a pot experiment in greenhouse with singly and joint treatment at different concentrations, to examine their effects on composition and diversity of soil microorganisms and availability of soil macronutrients by using high-throughput Illumina sequencing approach. The results showed both PFOA and PFOS application significantly increased soil NO3--N and NH4+-N content, but did not alter total phosphorus content, compared to the control check (CK) treatments. Total potassium content was reduced in PFOA treatments but increased in PFOS and PFOA×PFOS treatments. The most dominant bacterial phylum was Chloroflexi in low and medium PFCs concentrations and the CK treatments, but it was switched to Acidobacteria in high concentrations. No obvious change was detected for the composition of the dominant fungi community in PFCs treatments compared to the CK treatments. With the increase of PFCs concentrations, soil bacterial richness decreased but its diversity increased, whereas the richness and diversity of fungal community usually decreased. Redundancy analyses revealed that soil fungal community was more sensitive to PFCs pollutants than soil bacterial communities. Further data analysis revealed by structural equation model (SEM) that the PFCs exposed for 60 days indirectly affects the diversity and richness of soil bacteria and fungi by directly affecting NO3--N and NH4+-N content. The results suggested the concentration of PFCs pollutants played a primary role in determining the composition, richness and diversity of forest soil microbial communities.https://opus.govst.edu/fac/1187/thumbnail.jp
Allelopathic Mechanisms in Camellia oleifera- Arachis hypogaea L. Intercropping
No full textTree-crop intercropping is of great significance in food security, land protection, and sustainable agriculture. However, the mechanisms of allelopathy between plant species during intercropping are still limited. This study focuses on the allelopathic effects in the intercropping between Camellia oleifera and Arachis hypogaea L. in southern China. We use different parts of the C. oleifera extract to evaluate their impact on peanut seed germination. The results showed that it has inhibitory effects on peanut germination and growth, with the fruit shell having the strongest inhibitory effect. Three main allelopathic substances affecting A. hypogaea germination and growth were identified using gas chromatography–mass spectrometry (GC-MS) analysis, namely, 2,4-di-tert-butylphenol, hexanal, and benzaldehyde. Transcriptomics and metabolomics analyses revealed their effects on glutathione metabolism pathways and specific gene expression. In summary, this study reveals the allelopathic interaction mechanism between C. oleifera and A. hypogaea, which helps to better understand the role of allelopathy in intercropping practices between trees and crops.https://opus.govst.edu/fac/1175/thumbnail.jp

Interplanting Leguminous Shrubs Boosts the Trophic Interactions of Soil Micro-food Web in a Karst Grassland
No full textNitrogen (N) is an essential nutrient for ecosystem productivity, restoration and succession processes. Biological N fixation and chemical N addition are both important strategies for accessing N nutrients in soil ecosystem. However, it is unclear which N supplement strategies is more effective in restoring ecosystem stability, particularly in soil micro-food web component, which plays a crucial role in nutrient cycling. Here, an in-situ study was conducted in a natural grassland to investigate the effects of N supply on soil microbial and nematode communities by three legume species: Amorpha fruticose (AF), Derris fordii (DF), and Indigofera atropurpurea (IA) at two interplanting densities (1: low density, 1.5 × 2 m; and 2: high density, 1 × 1 m), and by two N fertilization rates (N5: 5 g N m−2 y−1 and N10: 10 g N m−2 y−1). Results showed the microbial biomass of total-PLFA, bacteria, fungi, actinomycetes and chlorophyta increased by DF1 and IA2, and the biomasses of total nematodes, herbivores and omnivores were promoted by AF1, AF2 and DF1, but the biomass of most components was inhibited by N fertilizers. The interactions of soil micro-food web were complicated by DF1 and DF2, but simplified by N5 and N10. Furthermore, different N supplement strategies showed distinct energy flow patterns, such as the bacterial channel was promoted exclusively in AF2, the plant channel was enhanced in AF1 and AF2, and the fungal channel was boosted in DF1 and DF2 but declined in N5 and N10. These results demonstrated that the structure and energy flow of the soil micro-food web might be benefited by legume interplanting but impaired by N fertilizers. In particular, interplanting with D. fordii granted a more sustainable way of N supplementation for promoting the complexity and stability of the soil micro-food web, compared to interplanting with other legume species. Our findings provide better understanding of the interactions between legumes and soil biota and have important implications for sustainable restoration of degraded karst grasslands.https://opus.govst.edu/fac/1066/thumbnail.jp
Unraveling Perceptions on Wrongful Convictions: Do Gender and Ethnicity Explain Disparities in Views?
No full textThis research employs a convenience sample survey design to explore the complex interaction between race, gender, and public perceptions of wrongful convictions. Examining 324 responses from diverse groups, the study finds that these views are not uniform across different demographics. African Americans and women exhibit significantly heightened perceptions of wrongful convictions and more robust support for justice reform. The regression results also highlight that age, education, and professional background in law enforcement significantly influence these perspectives. Notwithstanding its limitations, the study forms foundation for further inquiry into the role of socio-demographic factors in shaping public attitudes toward criminal justice system.https://opus.govst.edu/fac/1030/thumbnail.jp
