Additions to the Known Endemic Flora and Fauna of Arkansas
Robison and Smith\u27s (1982) list of endemic species of Arkansas rendered a valuable service to the community of biologists interested in the endemic biota of the state. These authors listed seven species of plants and forty species of animals endemic to Arkansas. This paper stimulated my interest in the endemic biota of the Ozark/Ouachita Mountain region of Missouri, Arkansas, and Oklahoma. During the course of compiling a list of Ozark/Ouachita endemic species several references were found that listed Arkansas endemic taxa inadvertently overlooked by Robison and Smith. Most notable among these references was Chamberlin and Hoffman (1958), Checklist of the Millipeds of North America. This paper chronicles the work of N. B. Causey and R. V. Chamberlin who describe thirty-two species of endemic Arkansas Millipeds. These records as well as a few additional records for other animal and plant taxa are presented in this paper
New Species of Occasjapyx From the Interior Highlands (Insecta: Diplua: Japygidae)
A new species of Japygidea, Occasjapyx carltoni is described from the Ozark Mountains of the Interior Highlands. This is the first record of the genus outside of California in North America. The genus is also known from China and Japan

Professor Scheppele’s Middle Way: On Minimizing Normativity and Economics in Securities Law
Hydrodynamic pressures on sloping dams during earthquakes. Part 2. Exact theory
The equations for the earthquake forces on a rigid dam with an inclined upstream face of constant slope are solved exactly by two-dimensional potential-flow theory. The distribution of the hydrodynamic pressure along the upstream face and the total horizontal, vertical and normal loads on the dam are computed from the integral solutions. The results obtained from the exact theory are compared with those derived from the momentum-balance method and there is reasonable agreement
Commentary on the Limits of Compensation and Deterrence in Legal Remedies
Allen comments on papers written by James Cox and Deborah DeMott regarding the deterrence of corporate misconduct. He examines the limits of compensation and deterrence as legal remedies
System Description for a Scalable, Fault-Tolerant, Distributed Garbage Collector
We describe an efficient and fault-tolerant algorithm for distributed cyclic
garbage collection. The algorithm imposes few requirements on the local
machines and allows for flexibility in the choice of local collector and
distributed acyclic garbage collector to use with it. We have emphasized
reducing the number and size of network messages without sacrificing the
promptness of collection throughout the algorithm. Our proposed collector is a
variant of back tracing to avoid extensive synchronization between machines. We
have added an explicit forward tracing stage to the standard back tracing stage
and designed a tuned heuristic to reduce the total amount of work done by the
collector. Of particular note is the development of fault-tolerant cooperation
between traces and a heuristic that aggressively reduces the set of suspect
objects.Comment: 47 pages, LaTe
