10. Perspectives on the Principalship: Principal, Teacher, and Student Perceptions of Principal Leadership

Author

Richey, Charles Sean

Abstract

The principalship is second only to teachers in its effect on student learning (Leithwood et al., 2004). This study examined and compared the perceptions of principals, teachers, and students regarding the different dimensions of principal leadership. The study took place in a large school district in California's central valley. Focus groups of principals and teachers were used to identify themes for analysis of principal leadership. Students from a comprehensive high school were surveyed to solicit their views on how principals exercise leadership. This study found that principals and teachers both firmly believe that the essential work of the principalship is to support students and student learning. Principals felt constrained by conflicting district and parent demands, which pulled them away from working with students and limited their ability to focus on learning and instruction. The teachers felt frustrated by their lack of involvement as colleagues and professionals in the school leadership process. Student survey responses indicated that students did not feel that adults held high interest in them outside of school, nor did students feel connected to adults at school. These findings imply that principals should involve teachers more fully in school-based decisions and should train their teachers to build stronger positive relationships with their students. These findings further suggest that principals should involve students more fully in the decisions made regarding student learning as a means of strengthening student connection to their school.

Abstract

The North Atlantic Basin (NAB) has seen an increase in the frequency and intensity of tropical cyclones since the 1980s, with record-breaking seasons in 2017 and 2020. However, little is known about how coastal ecosystems, particularly mangroves in the Gulf of Mexico and the Caribbean, respond to these new “climate normals” at regional and subregional scales. Wind speed, rainfall, pre-cyclone forest height, and hydro-geomorphology are known to influence mangrove damage and recovery following cyclones in the NAB. However, previous studies have focused on local-scale responses and individual cyclonic events. Here, we analyze 25 years (1996–2020) of mangrove vulnerability (damage after a cyclone) and 24 years (1996–2019) of short-term resilience (recovery after damage) for the NAB and subregions, using multi-annual, remote sensing-derived databases. We used machine learning to characterize the influence of 22 potential variables on mangrove responses, including human development and long-term climate trends. Our results document variability in the rates and drivers of mangrove vulnerability and resilience, highlighting hotspots of cyclone impacts, mangrove damage, and loss of resilience. Cyclone characteristics mainly drove vulnerability at the regional level. In contrast, resilience was driven by site-specific conditions, including long-term climate trends, pre-cyclone forest structure, soil organic carbon stock, and coastal development (i.e., proximity to human infrastructure). Coastal development is associated with both vulnerability and resilience at the subregional level. Further, we highlight that loss of resilience occurs mostly in areas experiencing long-term drought across the NAB. The impacts of increasing cyclone activity on mangroves and their coastal protection service must be framed in the context of compound climate change effects and continued coastal development. Our work offers descriptive and spatial information to support the restoration and adaptiv

Abstract

Through litter decomposition enormous amounts of carbon is emitted to the atmosphere. Numerous large-scale decomposition experiments have been conducted focusing on this fundamental soil process in order to understand the controls on the terrestrial carbon transfer to the atmosphere. However, previous studies were mostly based on site-specific litter and methodologies, adding major uncertainty to syntheses, comparisons and meta-analyses across different experiments and sites. In the TeaComposition initiative, the potential litter decomposition is investigated by using standardized substrates (Rooibos and Green tea) for comparison of litter mass loss at 336 sites (ranging from −9 to +26 °C MAT and from 60 to 3113 mm MAP) across different ecosystems. In this study we tested the effect of climate (temperature and moisture), litter type and land-use on early stage decomposition (3 months) across nine biomes. We show that litter quality was the predominant controlling factor in early stage litter decomposition, which explained about 65% of the variability in litter decomposition at a global scale. The effect of climate, on the other hand, was not litter specific and explained <0.5% of the variation for Green tea and 5% for Rooibos tea, and was of significance only under unfavorable decomposition conditions (i.e. xeric versus mesic environments). When the data were aggregated at the biome scale, climate played a significant role on decomposition of both litter types (explaining 64% of the variation for Green tea and 72% for Rooibos tea). No significant effect of land-use on early stage litter decomposition was noted within the temperate biome. Our results indicate that multiple drivers are affecting early stage litter mass loss with litter quality being dominant. In order to be able to quantify the relative importance of the different drivers over time, long-term studies combined with experimental trials are needed.

22. Saltwater Intrusion and Vegetation Shifts Drive Changes in Carbon Storage in Coastal Wetlands

Author

Abstract

Coastal wetlands protect coastlines through efficient storage of organic carbon (OC) that decreases wetland vulnerability to sea level rise (SLR). Accelerated SLR is driving saltwater intrusion and altering vegetation communities and biogeochemical conditions in coastal wetlands with uncertain implications. We quantified changes in OC stocks and fluxes driven by 1) saltwater and phosphorous intrusion on freshwater and brackish marshes, 2) vegetation along an experimental saltmarsh to mangrove gradient, 3) saltwater intrusion and vegetation change across a marsh to mangrove ecotone, and 4) vegetation change and mangrove forest development along a marsh to mangrove ecotone. Increasing salinity in freshwater marshes decreased root biomass and soil elevation within one year. In brackish marshes, increased salinity decreased root productivity and biomass and increased root breakdown rate (k), while added salinity did not increase elevation loss. In our experimental marsh-mangrove ecotone, mangrove vegetation promoted higher organic carbon (OC) storage by increasing above and belowground biomass and reducing organic matter k. However, mangroves also increased belowground k, and decreased allochthonous marine subsidies, indicating the potential for OC storage trade-offs. In the Southeast Everglades, we identified strong interior-coastal gradients in soil stoichiometry and mangrove cover. Interior freshwater soil conditions increased k, while total soil OC stocks decreased toward the coast indicating that saltwater intrusion is driving large scale soil OC loss. In the southeast Everglades, mangrove expansion increased root biomass and root productivity, but did not mitigate the overall loss of OC stocks toward the coast. Similarly, in the southwest Everglades, saltwater intrusion drove a decrease in soil OC. However, mangrove encroachment drove a rapid recovery and increased OC stocks. Mangrove encroachment doubled aboveground biomass within the last ten years, increased it

28. Aircraft Heads Up Display design and optimization as applied to the AV-8B Harrier

Author

Gray, Charles Sean

Abstract

Though the advent of the Heads Up Display (HUD) has dramatically changed the way information is presented to aircrew during flight, the requirement to select and discern the pertinent information applicable to the task at hand has not. Much like the proliferation of gauges and switches in a 60's and 70's era military cockpit interfered with a quick and efficient scan of the instruments, so to do the number of pieces of information being presented in a HUD. With the selection of the AV-8B to be the lead platform in implementation of the Open System Core Avionics Requirement (OSCAR), a rehosting of the Operational Flight Program (OFF), has come the opportunity to optimize the HUD design of the AV-8B. This thesis focuses on an attempt to simplify and standardize the current HUD displays and improve the tailoring of reject sub-modes that are designed to decrease the amount of data being displayed. The potential benefits of HUD modes that could be instructor configured and selectable in-flight to facilitate the development of the proper scan and reduce the time required for pilots to gain proficiency are also addressed.
