Tiny Drifters Amidst Global Change: Examining Environmental Drivers, Trophic Impacts, And Management Strategies Of Estuarine Plankton Communities In The Anthropocene, Taylor Nicole Dodrill

Dissertations and Theses

Plankton productivity supports estuarine food webs, and has been tied to the success of fisheries, macroinvertebrates, and cultured shellfish yields. Climate change and alterations to nutrient loads are thought to be influencing plankton assemblages, with toxin-producing harmful algal blooms (HABs) on the rise and nutritional quality of plankton declining globally. These shifts in plankton communities may contribute to low biomass yields and toxin-based closures of important fisheries. The objectives of this dissertation are to identify environmental drivers, trophic impacts, and management strategies to understand and respond to changing estuarine plankton communities. To address these objectives, I used a combination of …

2020-Current year OA Pubs

Challenging skeletal repairs are frequently seen in patients experiencing systemic inflammation. To tackle the complexity and heterogeneity of the skeletal repair process, we performed single-cell RNA sequencing and revealed that progenitor cells were one of the major lineages responsive to elevated inflammation and this response adversely affected progenitor differentiation by upregulation of Rbpjk in fracture nonunion. We then validated the interplay between inflammation (via constitutive activation of Ikk2, Ikk2ca) and Rbpjk specifically in progenitors by using genetic animal models. Focusing on epigenetic regulation, we identified Rbpjk as a direct target of Dnmt3b. Mechanistically, inflammation decreased Dnmt3b expression in progenitor cells, …

Development And Validation Of Ethical Blindness Scale, Darija Aleksić, Guido Palazzo

Economic and Business Review

Recent models of ethical decision making have underlined the influence of unconscious processes of unethical behavior, and ethical blindness has been identified as a construct that deepens the understanding of unintentional unethical behavior. However, to date, no empirically tested measure of ethical blindness exists. Consequently, we have explored and developed a tool for measuring ethical blindness, which is presented in this paper. Based on qualitative data from interviews with individuals employed in different industries and a literature review, we developed a multidimensional measure of ethical blindness. The measure was tested and validated in several consecutive steps on three quantitative data …
