Citation Statistics

This is a report about the use and misuse of citation data in the assessment of scientific research. The idea that research assessment must be done using ``simple and objective'' methods is increasingly prevalent today. The ``simple and objective'' methods are broadly interpreted as bibliometrics, that is, citation data and the statistics derived from them. There is a belief that citation statistics are inherently more accurate because they substitute simple numbers for complex judgments, and hence overcome the possible subjectivity of peer review. But this belief is unfounded.Comment: This paper commented in: [arXiv:0910.3532], [arXiv:0910.3537], [arXiv:0910.3543], [arXiv:0910.3546]. Rejoinder in [arXiv:0910.3548].

The development of an autonomous rendezvous and docking simulation using rapid integration and prototyping technology

A generic planar 3 degree of freedom simulation was developed that supports hardware in the loop simulations, guidance and control analysis, and can directly generate flight software. This simulation was developed in a small amount of time utilizing rapid prototyping techniques. The approach taken to develop this simulation tool, the benefits seen using this approach to development, and on-going efforts to improve and extend this capability are described. The simulation is composed of 3 major elements: (1) Docker dynamics model, (2) Dockee dynamics model, and (3) Docker Control System. The docker and dockee models are based on simple planar orbital dynamics equations using a spherical earth gravity model. The docker control system is based on a phase plane approach to error correction

Sister Union Strikes and No Strike Clauses: The Logic and Necessity of a Presumption of Inclusivity

This Comment examines the problem of sister union strikes and the potential it has of occurring in the private sector any time two distinct bargaining units work side by side. The problem is complicated further when one bargaining unit is under a collective bargaining agreement containing a no-strike clause. This Comment discusses various theoretical approaches to this problem and examines the unique legal background of this issue

Proof of Jacobi identity in generalized quantum dynamics

We prove that the Jacobi identity for the generalized Poisson bracket is satisfied in the generalization of Heisenberg picture quantum mechanics recently proposed by one of us (SLA). The identity holds for any combination of fermionic and bosonic fields, and requires no assumptions about their mutual commutativity.Comment: 9 pages, plain tex file, IASSNS-HEP-93/4
