Summary: This paper presents:(1) an historical review of the
development of Malecot's isolation by distane model, (2) a synthetic
summary of empirical results from four major components of the middle
Dalmation population system, (3) a novel table of "critical" values of
Malecot's parameter "b" to aid in the interpretation of isolation by
distance effects, and (4) a simulation study designed to analyze the power
of the quadratic assignment procedure for testing the significance of
Pearson's product-moment and Spearman's rank-order correlation
coefficients. The qudratic assignment test for Pearson's product-moment
correlation coefficient is satisfactory only for values of "b" and "E"<
0.10. For these values, Pearson's test is more powerful than Spearman's.

Summary: Assessing statistical significance of correlation between
distance matrices is difficult due to problems arising from nonlinearity of
relationship and interdependencies between pair-wise distances in each
matrix. Quadratic assignment procedure has been proposed as a valid
permutation test of association between matrices. In this paper power of
the quadratic assignment strategy applied to Pearson's correlation
coefficient is estimated on simulated distance matrices. Power of the test
is satisfactory for range of values of model parameters and error variance
which are often reported in literature.
Keywords: quadratic assignment, power of test, correlation between matrices

Summary: This paper describes the immunogenicity of a special
preparation of the Marek's disease vaccine HVT FC-126, used in commercial
Hybro fattening chickens. The vaccine which can be used resuspended in
sterile distilled water, was administered to a group of 70 day-old chickens
by use of ultrasonic nebulizer which generates particles of 2 to 7 microns
size. Thirty unvaccinatedchickens served as control. HVT FC-126 vaccine
which was applied deep into the respiratory system of chickens, did not
induce any adverse vaccinal reaction. At the end of the trial at 42 days of
age the average body weight amounted to 1.716 g and 1.725 g in vaccinated
and control chickens respectively. Used HVT FC-126 ("Marikal" - PLIVA,
Zagreb)showed to be immunogenic.

Summary: Recent results on interval eigenvalue problem are applied
to
twodimensional interval symmetric matrices. This analysis has served as a
basis for the construction of interval Jacobi method. The method does not
converge always, but it always provides intervals containing the
eigenvalues. Interval Jacobi method can be applied to both, interval
symmetric and real symmetric matrices. In the latter case the final
intervals result from the process of accommodating the impacts of rounding
errors. The intervals obtained by numerical tests on real matrices comply
with the theoretical error bounds, and the method never diverged. On
interval matrices the method converges on smaller matrices even if lower
and upper bounds of their elements agree in only 2--3 most significant
digits.

Summary: Recent Deif's results on symmetric interval eigenvalue
problem are applied to twodimensional interval symmetric matrices. For
symmetric interval matrices of higher dimension the results apply only to
eigenvalues belonging to eigenvectors with sign patterns constant over the
interval matrix. Bounds on the width of the interval matrix sufficient for
the invariance of eigenvector sign pattern are hard to verify. Constraining
the symmetric interval matrices to subsets of symmetric point matrices is
natural for many applications. When twodimensional symmetric interval
matrix is constrained to its subset containing only symmetric point
matrices, it is possible to characterize the sets of its eigenvalues and
eigenvectors without bounding its width. These characterizations are a
basis for the construction of interval Jacobi method.
