"TAKEN" DYNAMICS TO THE SPATIAL DOMAIN

 

The foundation for time series analysis methods to detect chaos is the notion that phase spaces and dynamics of a nonlinear dynamical system (NDS) can be reconstructed from a single variable, based on Takens embedding theorem (Takens, 1981). Many years ago (Phillips, 1993) I showed that temporal-domain chaos in the presence of anything other than perfect spatial isotropy (and when does that ever happen in the real world?) leads to spatial-domain chaos. This implies an analogous principle in the spatial domain.

Assume an Earth surface system (ESS) characterized by n variables or components xi, i = 1, 2, . . , n, which vary as functions of each other:

ESS = f(x1, x2, , , , xn)

If spatial variation is directional along a gradient y (of e.g., elevation, moisture, insolation) then

dxi/dy = f(x1, x2, , , , xn)

dx2/dy = f(x1, x2, , , , xn)

THE SEMANTICS OF RESILIENCE

 

Resistance of environmental systems is their capacity to withstand or absorb force or disturbance with minimal change. In many cases we can measure it based on, e.g., strength or absorptive capacity. Resilience is the ability of a system to recover after a disturbance or applied force to (or toward) its pre-disturbance condition—in many cases a function of dynamical stability. In my classes I illustrate the difference by comparing a steel bar and a rubber band. The steel bar has high resistance and low resilience—you have to apply a great deal of force to bend it, but once bent it stays bent. A rubber band has low resistance and high resilience—it is easily broken, but after any application of force short of the breaking point, it snaps back to its original state.

Unravelling the Mysteries of Neutrinos

Dr. Stephen Parke Fermilab Neutrinos are the most numerous massive particles in the Universe. Their masses are very tiny, no larger than one millionth the mass of the electron. Are they like all the known massive fermions, being four component particles, or are they a new type of fermion never seen before, a two component fermion? Are there only only three neutrinos or are there more species of neutrinos? Of the three neutrinos we know of, we have determined part of the massing pattern but not the completely pattern.

"Perverse Subjects: Becoming Bodies of Literature in the Library"

The second in the “Works in Progress Series” features Melissa Adler, Assistant Professor in the School of Library and Information Science. She will be discussing the introduction to her book manuscript, tentatively titled Perverse Subjects: Becoming Bodies of Literature in the Library. The book provides an account of the ways in which the Library Congress classification standards that organize research libraries in the U.S. and abroad have reproduced normative ideas about sexuality since the beginning of the 20th century. The project challenges these classifications through the lens of perversion, echoing Eve Kosofsky Sedgwick’s call to become “perverse readers.”

Carol Mason (GWS) and Rusty Barrett (Linguistics) will serve as respondents. Attendees should email CST Director Dr. Marion Rust (marion.rust@uky.edu) for a copy of Dr. Adler’s paper.

Long Time Ago... A Performance by Crit Callebs Eastern Band Cherokee Storyteller

 
Crit Callebs (Eastern Band Cherokee descendant) is a traditional hunter, food gatherer, and fire-tender and lives on the Yakama Nation Indian Reservation. He is completing his Master’s Degree at Central Washington University (CWU) in Cultural Resource Management with an expertise in treaty rights concerning Indian hunting and fishing. He served as the Native American Liaison at the Center for Diversity and Social Justice and was a very popular guest lecturer for the American Indian Studies program. Crit is a trainer for the “Since Time Immemorial” tribal sovereignty and history curriculum implemented in K-12 classrooms in Washington State. As an active member of the Northwest Indian Storytelling Association he has been a featured storyteller for the Tseil-Waututh Nation, CWU Museum of Culture and Environment, Colville Tribes Youth “Warrior Camp” and is the 2014 Alaska Spirit of Reading storyteller. Crit is also a professional survival trainer and former instructor for the world renowned Boulder Outdoors Survival School. One of his great passions is teaching youth and adults how to be self-reliant in the wilderness. Using his gift of storytelling, he travels throughout the U.S. and Canada sharing traditional stories, teaching cultural camps and conducting workshops that promote self-awareness, ancestral skills, and Indigenous values.
