Insights from Complexity: A Study of the Implementation of a District-Wide Literacy Initiative through the Lens of Complex Systems Theory

Complexity Theory provides unique insights into the implementation and operations of a district literacy initiative. The successful and unsuccessful structures of the literacy initiative are examined through a complexity lens in order to gain insight into the relationships between elements of a complex system and its processes operating within a “top-down” educational directive and the resulting “bottom-up” resistance. This qualitative study uses a phenomenological approach to advance complex systems theory. This allows a multi-dimensional exploration of the fundamental attributes of the district initiative, its processes and the relationships within those processes. The literacy initiative in a large urban school district is considered from the experiences of members at every level of the system. Intricate interactions of the participants within the system are explored through the lens of complexity in order to gain an understanding for future implementation of literacy initiatives. For the purpose of the research, the district, the classroom, the faculty, the students, and their learning are considered by the study to be components of a complex adaptive system, as well as Complex Adaptive Systems in and of themselves. The study of the interconnectedness among these agents illuminates the activities and structures within the system design that facilitate or hinder meaningful change for the system

Modeling radiation belt radial diffusion in ULF wave fields: 2. Estimating rates of radial diffusion using combined MHD and particle codes

[1] Quantifying radial transport of radiation belt electrons in ULF wave fields is essential for understanding the variability of the trapped relativistic electrons. To estimate the radial diffusion coefficients (DLL), we follow MeV electrons in realistic magnetospheric configurations and wave fields calculated from a global MHD code. We create idealized pressure-driven MHD simulations for controlled solar wind velocities (hereafter referred to as pressure-driven Vx simulations) with ULF waves that are comparable to GOES data under similar conditions, by driving the MHD code with synthetic pressure profiles that mimic the pressure variations of a particular solar wind velocity. The ULF wave amplitude, in both magnetic and electric fields, increases at larger radial distance and during intervals with higher solar wind velocity and pressure fluctuations. To calculate DLL as a function of solar wind velocity (Vx = 400 and 600 km/s), we follow 90 degree pitch angle electrons in magnetic and electric fields of the pressure-driven Vx simulations. DLL is higher at larger radial distance and for the case with higher solar wind velocity and pressure variations. Our simulated DLL values are relatively small compared to previous studies which used larger wave fields in their estimations. For comparison, we scale our DLL values to match the wave amplitudes of the previous studies with those of the idealized MHD simulations. After the scaling, our DLL values for Vx = 600 km/s are comparable to theDLL values derived from Polar measurements during nonstorm intervals. This demonstrates the use of MHD models to quantify the effect of pressure-driven ULF waves on radiation belt electrons and thus to differentiate the radial diffusive process from other mechanisms
