Environmental factors controlling biochar climate change mitigation potential in British Columbia's agricultural soils
To combat climate change, carbon dioxide must be prevented from entering the atmosphere or even removed from it. Biochar is one potential practice to sequester carbon, but its climate change mitigation potential depends on a multitude of parameters. Differentiating areas of low and high climate change mitigation through biochar addition is key to maximize its potential and effectively use the available feedstock for its production. This study models the realistic application of 1 metric tonne (t) per hectare (ha) of forest harvest residue derived biochar over the climatically and pedologically diverse agricultural area of British Columbia, Canada, and provides a framework and assumptions for reproducibility in other parts of the world. The model accounts for the direct (input of organic carbon) and indirect (enhanced plant biomass) effects of biochar on soil organic carbon stock, its impact on nitrous oxide emissions from soils, and the avoided emissions from the reduced lime requirement due to biochar's alkalinization potential. Impacts are modelled over 20‐year time horizon to account for the duration and magnitude variation over time of biochar effect on plant biomass and nitrous oxide emissions from soil and conform to the IPCC GWP 20‐year time horizon reporting. The results show that a single application of 1 t of biochar per ha−1 can mitigate between 3 and 5 t CO2e ha−1 over a 20‐year time frame. Applied to the 746,000 ha of agricultural land of British Columbia this translate to the mitigation of a total of 2.5 million metric tonnes (Mt) CO2e over a 20‐year time frame. Further, the results identify agricultural areas in the Lower Mainland region (the southwestern corner of British Columbia) as the area maximizing climate change mitigation potential through biochar addition due to a combination of relative high temperature, high precipitation, and crops with high nitrogen requirement. This study models the application of 1 t ha−1 of forest harvest residue derived biochar over the agricultural area of British Columbia, Canada, and offers a framework for reproducibility. It accounts for the direct (input of organic carbon) and indirect (enhanced plant biomass) effects of biochar on soil organic carbon stock, its impact on nitrous oxides emissions from soils, and the reduced lime requirement due to biochar's alkalinization potential. The results show that a single application of 1 t of biochar can mitigate between 3 and 5 t CO2e per hectare.

من مكة إلى الميتاداتا : فكر القرن الحادي والعشرين عند قدماء العرب /
يأتي كتاب (من مكة إلى الميتاداتا.. فكر القرن الحادي والعشرين عند قدماء العرب) الصادر عن دار نهضة مصر، للدبلوماسي السابق مايكل هاميلتون مورجان ليرد الاعتبار للحضارة العربية الإسلامية، كاشفا كيف سبق علماؤها أوروبا بقرون، وذلك في ظل تجاهل الغرب لأسماء علماء العرب والمسلمين وإسهاماتهم وتلقين أجيالهم أن هذه التطورات يعود أصلها لكشوفات تمت في أوروبا، والحقيقة أن الإسهامات العربية التي حدثت في الأغلب كانت قبل 500 أو 800 عام من عصر الكشوفات الأوروبية، مما أسهم في تشكيل النظرة السلبية المغلوطة للثقافة العربية الإسلامية باعتبارها حضارة منغلقة فكريا ومنعزلة عن حركة الكشوفات الإنسانية، لافتا إلى أن كلمة (معرفة) بأشكالها ذكرت في القرآن أكثر من 850 مرة أي في المرتبة الثانية بعد لفظ الجلالة، مما يدل على أن الأساس الديني للإسلام ينطوي على اكتساب المعرفة عن العالم. كما أوضح أن الحضارة العربية الإسلامية تناولت مفهوم الإشراك المجتمعي والتسامح متمثلة في أحاديث الرسول- صلى الله عليه وسلم- وبعض آيات القرآن.

How Perceptions of Family Communication are Associated with Parental Responses to Their Young Adolescents
The current study examined how parents’ perceptions of their family’s communication is associated with their expressions of affection, reactions to their child’s negative emotions, and their child’s social self-efficacy. Parents (
N
= 146), whose eldest child was between 10 and 15 years old, were recruited from Prolific and completed an online survey. Structural equation modeling indicated higher family conversation predicted higher perceptions of affection, adolescent social self-efficacy, more positive responses to negative emotions, and less negative responses to negative emotions. Furthermore, the model indicated that higher reports of conformity predicted more negative responses to negative emotions and fewer positive responses to negative emotions. Examining the impacts of family dynamics on young adolescents adds to the literature and provides further insight for family therapists about the impact of family dynamics.
Highlights
Extending the family communication research, this study sampled parents on their interactions with their young adolescents.
Also extending the family communication research, this study examined associations with reactions to their adolescents’ emotions.
Structural equation modeling was used.
Family conversation was associated with parental affection, positive responses to negative emotions, and perceptions of their adolescents’ social self-efficacy.
Family conformity was associated with responses to negative emotions.

Tunneling Spectroscopy as an All-Electrical Probe of Localized Quantum States in 2D Material Platforms
Advancing quantum sensing technologies requires reliable methods for detecting and characterizing localized quantum states, which can serve as sensitive probes of physical quantities such as electromagnetic fields, temperature, or strain at the nanoscale. This dissertation presents the development and application of tunneling spectroscopy in vertical two-dimensional (2D) material heterostructures as an all-electrical platform for sensing zero-dimensional quantum systems. Devices are fabricated using mechanically exfoliated 2D materials–primarily graphene and hexagonal boron nitride–forming tunnel junctions capable of electrically resolving the energy spectrum of electronic states within the tunnel barrier.The tunneling current is sensitive to both the energy spectrum and charge dynamics of localized states embedded within the barrier. Differential conductance measurements reveal features consistent with resonant tunneling through intrinsic defects in hBN as well as encapsulated molecular species. The platform’s modularity can be leveraged to integrate diverse quantum systems, while its compatibility with low-temperature and magneto transport measurements enables electrically detected magnetic resonance as a pathway for spin-sensitive studies. Design principles for the encapsulation of quantum systems are explored in addition to measurement considerations, and future directions are outlined–including the incorporation of magnetic contacts and the probing of spin blockade phenomena to demonstrate spin sensitivity.These results establish vertical 2D tunnel junctions as a versatile and modular platform for studying quantum states by purely electrical means, opening pathways for integrating solid-state quantum systems into next-generation devices.

Certain Professionals in an Uncertain Field During Unprecedented Times: Art Museum Educator Perspectives Through Museum Closures Caused by the COVID-19 Pandemic
The COVID-19 pandemic cause global social and cultural disruptions that caused institutions like museums to suddenly close. Stay-at-home orders forced organizations to restructure their now-remote staff, laying off, furloughing, or firing entire departments like museum education. The literature in the field suggests museum educators were fired or laid off at a higher rate than staff in other departments. It also bears that museum educators were more likely to be the staff that pivoted to virtual experiences during the lockdowns (Ennes et al., 2021; Krantz & Downey, 2021). That seeming contradiction guided my inquiry to better understand the toll this crisis took on art museum educators (AMEs), the scholarly field, and the profession. The comprehensive literature review showed who AMEs are and the challenges they face regarding their profession. The study was guided by a conceptual model based on overlapping feminist systems theory, participatory culture, and the sociology of expertise (Stephens, 2009; Jenkins, 2009; Brady, 2018). I worked with eight AMEs from mid-sized art museums in the US to generate the data through three phases: initial narratives, semi-structured interviews, and group discussions. I used the text, conversations, images, and media to present the findings as amalgam characters in fictive vignettes, further enhancing anonymity. I used narrative and arts-based inquiry methodologies, and thematic and visual narrative analysis to generate findings which led to two overall results. A primary result was many AMEs left their museum, and one left the field due to distrust in their institution to continue supporting their digital efforts. A secondary result was colleague support was a stronger influence than prior experience with digital programming, pointing to a participatory concept of expertise. AMEs have shown they can do a lot with a little, and support from their institution is key to their success.

Dairylands
This study explores how changes in the dairy industry have impacted the lives and social identities of small-scale dairy farms in the United States. Using a qualitative ethnographic approach, supported by a historical and literary review, I interviewed family farmers in three states once known for their robust dairy industries. Dairy, like many food industries, is subject to consolidation, monopolization, and other large trends occurring within the global agricultural economy. After four years of consistently low milk prices, many small dairies have been forced to exit the market. My conversations with farmers shed light on the ways in which land, legacy, and the social welfare of rural communities are intertwined. They also serve as a basis for my analysis of how the image of the family farmer has been used to reproduce inequalities in the global food system.

Uncoupling reproduction from metabolism extends chronological lifespan in yeast
Studies of replicative and chronological lifespan in Saccharomyces cerevisiae have advanced understanding of longevity in all eukaryotes. Chronological lifespan in this species is defined as the age-dependent viability of nondividing cells. To date this parameter has only been estimated under calorie restriction, mimicked by starvation. Because postmitotic cells in higher eukaryotes often do not starve, we developed a model yeast system to study cells as they age in the absence of calorie restriction. Yeast cells were encapsulated in a matrix consisting of calcium alginate to form ∼3 mm beads that were packed into bioreactors and fed ad libitum. Under these conditions cells ceased to divide, became heat shock and zymolyase resistant, yet retained high fermentative capacity. Over the course of 17 d, immobilized yeast cells maintained >95% viability, whereas the viability of starving, freely suspended (planktonic) cells decreased to <10%. Immobilized cells exhibited a stable pattern of gene expression that differed markedly from growing or starving planktonic cells, highly expressing genes in glycolysis, cell wall remodeling, and stress resistance, but decreasing transcription of genes in the tricarboxylic acid cycle, and genes that regulate the cell cycle, including master cyclins CDC28 and CLN1 . Stress resistance transcription factor MSN4 and its upstream effector RIM15 are conspicuously up-regulated in the immobilized state, and an immobilized rim15 knockout strain fails to exhibit the long-lived, growth-arrested phenotype, suggesting that altered regulation of the Rim15-mediated nutrient-sensing pathway plays an important role in extending yeast chronological lifespan under calorie-unrestricted conditions.
