Medical Illustration: Discovering and Comprehending Scientific Concepts Through Art
Background. Scientific illustrations and diagrams have been used for thousands of years to portray and relay information. As the different fields of science, technology, engineering and math progressed, diagrams evolved along with the scientific concepts they illustrated. Yet, there is no set standard for creating a scientific diagram or illustration. The field is continually evolving and growing, utilizing multiple dimensions including digital interfaces and virtual reality. Aims. To analyze the research on the use and effectiveness of different multimedia platforms for learning and to examine the effectiveness of learning outcomes using two dimensional vs three dimensional models. A specific focus was placed on level of detail and the role of color in medical diagrams. Another aim of this project was to develop novel medical illustrations and scientific diagrams based on these findings. Method. A literature search from January 1965 to January 2021 was conducted using the key words, scientific diagram, medical illustration, details, engagement, color, dimensions, models, learning, neuroscience, memory, among others. Databases and books from Union College\u27s Schaffer library were utilized. Findings. There was some evidence that the different components that make up scientific diagrams may influence learning outcomes. For example, some colors (i.e. warm) may facilitate learning. The value in the level of detail included in a diagram seems dependent on multiple factors such as subject material, intended audience etc., . It has been suggested that certain artistic styles of illustrations better facilitate learning over others (i.e. cartoons better facilitate learning of medical information over anatomical and CT scan imaging), but the research conducted in the field was limited by inconsistent methodologies across studies. Conclusions. Scientific illustration has real world implications given its use in educating the medical professionals and leaders in STEM fields of tomorrow, yet research on the effectiveness of learning aids is limited. Further research is needed to identify how different sensory information might enhance learning, especially as more digital interface platforms, learning aids, and virtual reality techniques are being developed

Spatial and Temporal Variability of Exchange Between Stream Waters and the Hyporheic Zone Using Laboratory Flume Experiments, Field Tracers, and Transient Storage Modeling
Groundwater-surface water interactions play a major role in regulating global water quality because they integrate diverse fluxes of water and its constituents within and beyond drainage basin boundaries. The hyporheic zone is the top portion of the unconfined, near-stream aquifer beneath and adjacent to streambed environments and facilitates riverine groundwater-surface water interactions. This continual transfer of water, dissolved constituents, particulate matter, and energy throughout the streambed is termed hyporheic exchange. As such, hyporheic exchange has the potential to influence a suite of critical riverine functions. While hydrologic research over the past century has improved our understanding of complex riverine processes at many spatial scales, ranging from individual plots and river reaches to entire catchments, there is still demand for improved predictions and understanding of hyporheic functions at larger spatial scales. Within the field of hyporheic zone research, there is a tendency to focus on smaller spatial scales because they are easier to characterize and relatively reduced in complexity. However, scaling up hyporheic exchange and its associated riverine processing is challenging because of increasing spatiotemporal complexity and heterogeneity associated with larger spatial scales. Thus, the field of hyporheic zone research is out of phase with hyporheic exchange prediction demands. The goal of this dissertation is to improve our understanding of hyporheic exchange spatiotemporal variability, through three independent manuscripts, to better meet demand for riverine processing predictions. Chapter 2 details experimental work focusing on hyporheic exchange at the sediment water interface in a recirculating laboratory flume. Chapters 3 and 4 employ reactive tracers to study hyporheic exchange from different spatiotemporal perspectives, downwelling flowpaths in the same season and stream reaches across two seasons, throughout different portions of the Jemez River, New Mexico. The results of this research provide a foundation for further study and development of hyporheic exchange scaling relationships as they pertain to riverine materials processing and water quality controlsDoctor of Philosoph

Neural control of the heart: developmental changes in ionic conductances in mammalian intrinsic cardiac neurons
The expression and properties of ionic channels were investigated in dissociated neurons from neonatal and adult rat intracardiac ganglia. Changes in the hyperpolarization-activated and ATP-sensitive K+ conductances during postnatal development and their role in neuronal excitability were examined. The hyperpolarization-activated nonselective cation current, I-h, was observed in all neurons studied and displayed slow time-dependent rectification. An inwardly rectifying K+ current, I-K(I), was present in a population of neurons from adult but not neonatal rats and was sensitive to block by extracellular Ba2+. Using the perforated-patch recording configuration, an ATP-sensitive K+ (K-ATP) conductance was identified in greater than or equal to 50% of intracardiac neurons from adult rats. Levcromakalim evoked membrane hyperpolarization, which was inhibited by the sulphonylurea drugs. glibenclamide and tolbutamide. Exposure to hypoxic conditions also activated a membrane current similar to that induced by levcromakalim and was inhibited by glibenclamide. Changes in the complement of ion channels during postnatal development may underlie observed differences in the function of intracardiac ganglion neurons during maturation. Furthermore, activation of hyperpolarization-activated and KATP channels in mammalian intracardiac neurons may play a role in neural regulation of the mature heart and cardiac function during ischaemia-reperfusion.

Conditions for linking school mathematics and moral education: a case study
In recent years the mathematics education research community has undergone a social turn towards a greater interest in the values and broader educational purposes of mathematics education, including issues of social justice and citizenship education. Building on these developing interests, this paper presents a conceptual framework that links the teaching of school mathematics with moral education. Then, in a case study involving two countries, England and Canada, this framework is used to explore the affordances and constraints faced by mathematics teachers in those countries if they want to intentionally practice moral education in the classroom
