Disagreement and Interpretation
The question of what weight--if any--courts should give to elected government resistance to court decisions is examined. A principle is sought that explains why courts should not consider local resistance when deliberating on constitutional questions
Indirect Constitutional Discourse: A Comment on Meese
Nagel responds to Alan J. Meese\u27s comments on Pres Clinton\u27s actions following the Supreme Court\u27s decision in Regents of the University of California v. Bakke. While the Clinton Administration\u27s strategy does not produce the best possible form of constitutional dialogue, it does produce another recognizable form of dialogue, one full of confusion and hypocrisy but a surprisingly central and entrenched part of the practice of judicial review itself
Effective-Lagrangian approach to gamma gamma --> WW; II: Results and comparison with e+e- --> WW
We present a study of anomalous electroweak gauge-boson couplings which can
be measured in e+e- and gamma gamma collisions at a future linear collider like
ILC. We consider the gauge-boson sector of a locally SU(2) x U(1) invariant
effective Lagrangian with ten dimension-six operators added to the Lagrangian
of the Standard Model. These operators induce anomalous three- and
four-gauge-boson couplings and an anomalous gamma gamma H coupling. We
calculate the reachable sensitivity for the measurement of the anomalous
couplings in gamma gamma --> WW. We compare these results with the reachable
precision in the reaction e+e- --> WW on the one hand and with the bounds that
one can get from high-precision observables in Z decays on the other hand. We
show that one needs both the e+e- and the gamma gamma modes at an ILC to
constrain the largest possible number of anomalous couplings and that the
Giga-Z mode offers the best sensitivity for certain anomalous couplings.Comment: 25 pages, 1 figure, 7 tables, comments, references and a table added;

Statistical Time Series Models of Pilot Control with Applications to Instrument Discrimination
A general description of the methodology used in obtaining the transfer function models and verification of model fidelity, frequency domain plots of the modeled transfer functions, numerical results obtained from an analysis of poles and zeroes obtained from z plane to s-plane conversions of the transfer functions, and the results of a study on the sequential introduction of other variables, both exogenous and endogenous into the loop are contained
Stability and Symmetry Breaking in the General Two-Higgs-Doublet Model
A method is presented for the analysis of the scalar potential in the general
Two-Higgs-Doublet Model. This allows us to give the conditions for the
stability of the potential and for electroweak symmetry breaking in this model
in a very concise way. These results are then applied to two different Higgs
potentials in the literature, namely the MSSM and the Two-Higgs-Doublet
potential proposed by Gunion at al. All known results for these models follow
easily as special cases from the general results. In particular, in the
potential of Gunion et al. we can clarify some interesting aspects of the model
with the help of the proposed method.Comment: 20 pages, 3 figures, extended version, typos corrected, references

Regenerative Dentistry - A Preliminary Study on Tooth Germs of the Mouse
OBJECTIVES: One of the most important bases in regenerative dentistry is the understanding of cell differentiation of the tooth germ. The preliminary study comprises the following: 1. micropreparation of tooth germs of the mouse and 2. cell examination after different periods of defined cell cultivation.
MATERIAL AND METHODS: The tooth germs were gently removed from mice under the microscope by means of micropreparation techniques. All of the germs were embedded in agar, positioned on Millipore Filters and cultivated over 14 and 21 days in a chemically
defined medium. For microscopic examination the germs were fixed, cut and stained with Giemsa- Romanowski and HE.
RESULTS: A cell layer on the Millipore Filters formed, which onginated either from dental pulp or from the outer enamel epithelium. Cells from the cell periphery appeared oblong with broad intermembranous areas. In the cell center the closely closed-up cells exhibited cubic cell form. After 14 days the cell nucleus appeared round and light blue after staining with Giemsa-Romanowski. In contrast, after 21 days a dark stained nucloeplasma was identified in the cells.
CONCLUSION: The results agree with previous studies on which tooth germs can be cultivated successfully in vitro. After the first observations the tooth germs did not show temporally co-ordinated growth and no differentiation as under in vivo conditions. A substantial reason for this lies in the lack of knowledge of the accurate environmental conditions necessery in vitro. With the cell
layer on the Milliopore Filters described here, the possibility of further investigations of cell differentiation exists
Playing Defense
Noting that the Romer opinion condemns the motives behind Amendment 2 without pausing even briefly to examine the social context in which it was enacted, Professor Nagel describes the decision as a model of the intolerant impulse in action. He traces this impulse to the Justices\u27 unwillingness to examine their own role--and that of the rest of the constitutional law establishment- in creating the underlying conditions that produced Amendment 2.
In order to identify those conditions, Professor Nagel analyzes the primary document used by Colorado for Family Values during its campaign on behalf of the initiative. He argues that this document could have persuaded moderate, unprejudiced voters because its underlying themes resonate with realistic fears about the possibility that gay-rights activists might be able to induce a social revolution through law-reform strategies that bypass normal democratic processes.
Amendment 2, then, may be traceable to anxiety and alienation rather than animosity. Professor Nagel concludes that judges and legal commentators should evaluate their own role (including decisions like Romer) in shaping a political culture where large segments of the public feel unable to exercise meaningful control over sudden and massive changes that threaten deeply valued ways of life
