Carbon Sequestration Potential of Urban Tree Species: A Case Study from Porbandar, India
Full text linkUrban ecosystems are integral to climate change mitigation through carbon sequestration. This study quantifies the carbon sequestration potential of 40 tree species at M.D. Science College, Porbandar, Gujarat, employing non-destructive methodologies. Key biometric parameters, including height, diameter at breast height (DBH), and biomass, were analysed to estimate carbon storage and CO₂ sequestration. The dataset reveals significant inter-species variations, with Ficus benghalensis leading in sequestration capacity, storing 1221.08 kg of carbon and sequestering 4476.84 kg of CO₂ per tree annually. Conversely, low biomass species such as Ziziphus mauritiana exhibit limited sequestration rates, highlighting a broad spectrum of ecological roles. tatistical analyses demonstrate moderate to strong correlations between DBH, biomass, and carbon sequestration rates, with DBH explaining up to 26.3% of variability in annual sequestration. Notably, tree count emerged as a strong predictor, accounting for 57.5% of sequestration variability, emphasizing the additive effect of increasing tree numbers. Collectively, the 516 trees on campus sequester an estimated 13,349.31 kg of CO₂ annually, underscoring the critical role of urban trees in mitigating atmospheric carbon levels. The findings advocate for integrating high-biomass, long-lived species in urban planning to enhance carbon offset, biodiversity conservation, and ecosystem services. This study provides actionable insights into urban forestry strategies for climate resilience, particularly in coastal semi-urban environments

Negotiating Power Relationships in Interprofessional Health Care Groups
No full textThis chapter examines the communication challenges associated with the hierarchical structure of power relationships among the health professions. It is commonly believed that balancing power relationships is crucial for successful interprofessional collaboration in providing patient care, but because hierarchy is deeply embedded in healthcare organizations, balancing power among health professionals may be an unrealistic ideal. This chapter therefore reframes thinking about professional hierarchy-from a monolithic absolute to a flexible and negotiable social order that can serve multiple purposes at different points in the patient care process. It proposes a communicative framework of interprofessional hierarchy negotiation that can help us to understand how interprofessional care groups can negotiate hierarchical power relationships in a way that improves collaboration without increasing conflict
Atomistic study of selenium doping effects on the mechanical properties of zinc-blende and wurtzite CdTe nanowires
No full textCdSexTe1–x semiconductor materials, having potential to be used to design dependable and reproducible nanowire devices, require an extensive study of their mechanical behaviors. The uniaxial tensile deformation mechanism of CdSexTe1–x nanowires (NWs) with different Se dopant concentration are yet to be explored. By integrating theoretical analysis with computational simulation, this research demonstrated that Se doping in CdTe NWs influences the mechanical response and failure modes. Ultimate tensile strength (UTS) and elastic modulus (EM) were studied for both zinc-blende (ZB) and wurtzite (WZ) structures with different crystal orientations. The findings revealed that these mechanical properties increase linearly with increasing Se concentration in all cases. In addition, the WZ structures exhibited similar mechanical properties under both zigzag and armchair loadings, unlike the ZB structures, which exhibited a strong dependence on the crystal orientation. The [111]-oriented ZB structures showed the highest EM and UTS whereas [100]-oriented ZB structures showed lowest EM and UTS. The failure mechanism was explored for CdSe50Te50 to underscore the influence of the dopant on the NWs failure for tensile loading. In both the cases of WZ structure, the failure planes were perpendicular to the loading direction. Furthermore, the failure plane varied with the Se content in ZB CdSexTe1–x. Atomic coordination and bond length affected by doping defined the alterations of mechanical properties and the preferred modes of failure. The significance of the interaction between doping elements and nanowire structures offers insights that unite material science and mechanics, contributing to the scientific understanding of solid materials’ behavio
Los Angeles Encampments
No full textMy most recent work is not created in the shelter of a studio, but outside on the streets of my community and city. This on-going body of work challenges the accepted practice of “en plein air” painting by presenting not the picturesque and beautiful, but ugly and dirty places most avoid at great length, and do not wish to even see, encampments of Los Angeles’s unhoused residents. Painting is slow. The people who live in the tents and bivouacs that I paint are often very curious and ask me about what I am doing. In this way my work opens up relationships and intimate interactions for me with a socio-economic population that is marginalized and maligned by society at large. For the past two decades my work has focused on those in extreme poverty, forced to make their homes on the street due to the inadequate supply of supportive and transitional housing in Los Angeles. My artwork is more than just paintings, it is an affirmation of my beliefs in social and economic justice, the truths I strive to live by, the energy, commitment, and effort to manifest that in the world
Who Do I Say I Am: A Review of Catholic Teachers’ Spiritual Identity and Factors Affecting Its Formation
No full textTeachers in Catholic schools are not only required to provide quality education through mastering the essential skills of pedagogy; they are also called to “be a reflection, albeit imperfect but still vivid, of the one Teacher” (Gravissimum educationis, 1965, para. 23). Thus, the spiritual identity of all teachers in Catholic schools, not only those who teach religious education, must be integrated with their professional identity. This review draws from 20 empirical peer-reviewed articles on Catholic school educators to understand how Catholic teachers see their spiritual identity as teachers and how these spiritual identities are formed. The results show that Catholic teachers understand their spiritual identity in teaching as vocation, mission, communion, profession, and evangelization. The factors that affect their spiritual identity include personal beliefs and faith life, context of school and society, and leadership and formation in schools. This will help teacher trainers and administrators to design their in-service teacher formation programs more effectively

Family Dynamics in \u3ci\u3eEverything, Everywhere, All At Once\u3c/i\u3e
No full textThis paper was originally a submission for my general psychology final. The prompt for it was to analyze any topic covered in class and connect to any form of fictional media. I chose to study the social psychology behind the relationships of immigrant parents and their children, connecting it to the movie Everything, Everywhere, All At Once by Daniel Scheinert and Daniel Kwan. I especially picked this movie because of how connected I felt to the characters in the movie as I have gone through some of the same experiences they have and know many immigrant children that have felt the same
Affordance-Based Information Technology Sensemaking [ABITS]
No full textInformation Technology (IT) use gives rise to a wide variety of outcomes. This stems in part from the divergent ways in which individuals understand technology. While the sensemaking literature unveils how meaning is attached to organizational phenomena via cognitive and social processes, it overlooks the discovery dimension of making sense, that is detecting the role of the IT artifact in bringing about outcomes. In other words, there is a need to explain how the IT artifact contributes to technology sensemaking and its outcomes. This paper presents a framework that enables scholars to analyze the IT artifact’s role in technology sensemaking and its outcomes. The paper proposes an Affordance-Based IT Sensemaking (ABITS) framework that explicates IT sense-made as a distinctive ontological arrangement among the users’ perceptions of technology affordances, the affordances that users actualize, and the user characteristics that underpin optimal adaptation. The study shows how these sense-made configurations lead to outcomes for individuals and organizations. This conceptual combination allows for the examination of user appropriations of new technology, as well as the integration of the IT artifact into accounts of IT sensemaking and its outcomes
Partnering for Pathogen Free Plants: Joining Forces to Keep Plants Healthy in the City of Tacoma Plant Holding Facility
Full text linkPartnerships between cities and universities can help overcome the challenges of producing healthy plants free of pests and pathogens for urban planting and restoration. In Tacoma, a partnership with researchers from Washington State University (WSU) helped the City of Tacoma implement best management practices in its plant holding facility (PHF). The PHF is a critical resource for improving open spaces, managing stormwater, and fostering community environmental stewardship throughout Tacoma and Pierce County. It supports urban forestry and natural area restoration by cultivating 8000 native plants and 1000 street trees for planting into restoration sites and neighborhood streets respectively. While many cities would benefit from similar facilities of their own, management can be challenging. For example, in fall 2021 a Phytophthora outbreak at the PHF led to the loss of hundreds of plants. Phytophthora is a genus of plant-damaging oomycetes (water molds) that thrive in wet conditions. Plant pathogens in this group spread through water and soil to cause diseases that can kill plants, possibly causing serious problems for planting stock, forests and restoration projects. Partnering with researchers from WSU was essential for collaboratively developing improved best management practices and implementing lessons learned by other small-scale nurseries. The partnership improved the function of the facility by helping address disease pathways, reduce re-infections with pot steaming, improve overall equipment hygiene, and train conservation crews
