Responding to Agency Avoidance of OIRA
Concerns have recently been raised that US federal agencies may sometimes avoid regulatory review by the White House Office of Information and Regulatory Affairs (OIRA). In this article, we assess the seriousness of such potential avoidance, and we recommend a framework for evaluating potential responses. After summarizing the system of presidential regulatory oversight through OIRA review, we analyze the incentives for agencies to cooperate with or avoid OIRA. We identify a wider array of agency avoidance tactics than has past scholarship, and a wider array of corresponding response options available to OIRA, the President, Congress, and the courts. We argue that, because the relationship between agencies and OIRA involves ongoing repeat player interactions, some of these avoidance tactics are less likely to occur (or to succeed) than has previously been alleged, and others are more likely; the difference depends significantly on how easy it is for OIRA to detect avoidance, and for OIRA, the courts, and others to respond. Further, we note that in this repeat player relationship, responses to agency avoidance tactics may induce further strategic moves and countermoves. Thus we further argue that the optimal response may not always be to try to eliminate the avoidance behavior; some avoidance may be worth tolerating where the benefits of trying to reduce agency avoidance would not justify the costs of response options and countermoves. We therefore conclude that responses to agency avoidance should be evaluated in a way similar to what OIRA asks of agencies evaluating proposed regulations: by weighing the pros and cons of alternative response options (including no action)
The physical and psychological factors predicting the onset and severity of environmental illness : a union perspective
ix, 118 leaves : ill. ; 28 cm.Includes abstract.Includes bibliographical references (leaves 100-107).Environmental Illness (EI) is thought to be precipitated by physical, psychological, social, and organizational factors. However, little research has focused on the psychological or organizational factors which may be associated with EI. The present exploratory field study examined differences in measures related to stress, social support, and physical and psychological symptoms associated with EI, among 525 hospital employees working in known EI and non-EI locations in the Metro Halifax Area. Although employees in EI locations experienced greater symptom severity, no consistent differences were found in the stress and social support measures between EI and non-EI locations. However, employees in EI locations with high symptom severity did report greater stress and lower social support than those with low symptom severity. Discriminant analyses revealed that the combined measures were relatively good at predicting group membership (EI vs non-EI locations). Structural modelling equations examining the relations among stress, social support, and symptom severity revealed that stress negatively predicted social support within EI and non-EI locations. Stress was found to be a direct predictor of symptom severity, but only among employees in EI locations. Unexpectedly, no significant association was found between social support and symptom severity in either EI or non-EI locations. This suggests that stress is related to greater symptom severity, but only for those people with low levels of social support

Spectral properties of random graphs with fixed equitable partition
We define a graph to be -regular if it contains an equitable partition
given by a matrix . These graphs are generalizations of both regular and
bipartite, biregular graphs. An -regular matrix is defined then as a matrix
on an -regular graph consistent with the graph's equitable partition. In
this paper we derive the limiting spectral density for large, random
-regular matrices as well as limiting functions of certain statistics for
their eigenvector coordinates as a function of eigenvalue. These limiting
functions are defined in terms of spectral measures on -regular trees. In
general, these spectral measures do not have a closed-form expression; however,
we provide a defining system of polynomials for them. Finally, we explore
eigenvalue bounds of -regular graph, proving an expander mixing lemma,
Alon-Bopana bound, and other eigenvalue inequalities in terms of the
eigenvalues of the matrix .Comment: 24 pages, 3 figure
The Viscous Nonlinear Dynamics of Twist and Writhe
Exploiting the "natural" frame of space curves, we formulate an intrinsic
dynamics of twisted elastic filaments in viscous fluids. A pair of coupled
nonlinear equations describing the temporal evolution of the filament's complex
curvature and twist density embodies the dynamic interplay of twist and writhe.
These are used to illustrate a novel nonlinear phenomenon: ``geometric
untwisting" of open filaments, whereby twisting strains relax through a
transient writhing instability without performing axial rotation. This may
explain certain experimentally observed motions of fibers of the bacterium B.
subtilis [N.H. Mendelson, et al., J. Bacteriol. 177, 7060 (1995)].Comment: 9 pages, 4 figure
Molecular elasticity and the geometric phase
We present a method for solving the Worm Like Chain (WLC) model for twisting
semiflexible polymers to any desired accuracy. We show that the WLC free energy
is a periodic function of the applied twist with period 4 pi. We develop an
analogy between WLC elasticity and the geometric phase of a spin half system.
These analogies are used to predict elastic properties of twist-storing
polymers. We graphically display the elastic response of a single molecule to
an applied torque. This study is relevant to mechanical properties of
biopolymers like DNA.Comment: five pages, one figure, revtex, revised in the light of referee's

Twirling Elastica: Kinks, Viscous Drag, and Torsional Stress
Biological filaments such as DNA or bacterial flagella are typically curved
in their natural states. To elucidate the interplay of viscous drag, twisting,
and bending in the overdamped dynamics of such filaments, we compute the
steady-state torsional stress and shape of a rotating rod with a kink. Drag
deforms the rod, ultimately extending or folding it depending on the kink
angle. For certain kink angles and kink locations, both states are possible at
high rotation rates. The agreement between our macroscopic experiments and the
theory is good, with no adjustable parameters.Comment: 4 pages, 4 figure
