Anomalies of the magnitude of the bias of the maximum likelihood estimator of the regression slope
(Athens Institute for Education and Research, 2015)The slope of the best-fit line y h x x 0 1 ( ) from minimizing a function of the squared vertical and horizontal errors is the root of a polynomial of degree four which has exactly two real roots, one positive and ... -
An investigation of the performance of five different estimators in the measurement error regression model
(Athens Institute for Education and Research, 2015)In a comprehensive paper by Riggs et al.(1978) the authors analyse the performances of numerous estimators for the regression slope in the measurement error model with positive measurement error variances >0 0 for X and ... -
So as not to despise God's grace: re-assessing Rahner's idea of the "anonymous Christian"
(Katholieke Universiteit Leuven, 2004)Rahner’s idea of the “anonymous Christian” is the best known, most controversial and most often misunderstood aspect of his theology. It is important to re-visit the idea because it is not an “optional extra” in his work ... -
On moduli stacks of G-bundles over a curve (Pre-published version)
(Springer, 2010)Let C be a smooth projective curve over an algebraically closed eld k of arbitrary characteristic. Given a linear algebraic group G over k, let MG be the moduli stack of principal G-bundles on C. We determine the set of ... -
Moduli stacks of vector bundles on curves and the King–Schofield rationality proof (Pre-published version)
(Springer, 2010)Let C be a connected smooth projective curve of genus g ≥ 2 over an algebraically closed field k. Consider the coarse moduli scheme Bunr,d (resp. Bunr,L) of stable vector bundles on C with rank r and degree d ∈ Z (resp. ... -
On semistable vector bundles over curves (Pre-published version)
(Elsevier, 2008)Let X be a geometrically irreducible smooth projective curve de ned over a eld k, and let E be a vector bundle on X. Then E is semistable if and only if there is a vector bundle F on X such that Hi(X; F E) = 0 for i = 0; ... -
Poincaré families and automorphisms of principal bundles on a curve (Pre-published version)
(Elsevier, 2009)Let C be a smooth projective curve, and let G be a reductive algebraic group. We give a necessary condition, in terms of automorphism groups of principal G-bundles on C, for the existence of Poincaré families parameterized ... -

Midwives to the mystery
(The Furrow, 1994)Christians should be capable of providing a response to people who ask the reason for the hope that they have (1 Peter 3:15). A reason, whatever else it is, is meant to be reasonable. Some thing appears reasonable if it ... -
A review of "Does God Care?" by Wilfrid Harrington

The non-ordained in ministry
(The Furrow, 1995)I have been asked by the Pastoral Commission of CORI (formerly the Conference of Major Religious Superiors) to provide some theological reflections arising out of the results of their survey of non-ordained ministers. ... -
A Europe without priests?
(The Furrow, 1996)The roles of bishop and priest are still pivotal authority positions in the Roman Catholic Church. Those who hold these positions need the qualities which inspire people, which can draw the best out of them, and which can ... -

Moment estimation of measurement errors
(NEDETAS, 2011)The slope of the best-fit line from minimizing a function of the squared vertical and horizontal errors is the root of a polynomial of degree four. We use second order and fourth order moment equations to estimate the ratio ... -
Revisiting some design criteria
(Athens Institute for Education and Research, 2015)We address the problem that the A (trace) design criterion is not scale invariant and often is in disagreement with the D (determinant) design criterion. We consider the canonical moment matrix CM and use the trace of its ... -
Limitations of the least squares estimators; a teaching perspective
(Athens Institute for Education and Research, 2016)The standard linear regression model can be written as Y = Xβ+ε with X a full rank n × p matrix and L(ε) = N(0, σ2In). The least squares estimator is = (X΄X)−1XY with variance-covariance matrix Coυ( ) = σ2(X΄X)−1, where ... -
A note on the computation of symmetric powers of hyperbolic forms and of trace froms on symbol algebras
(Scientific Advances Publishers, 2014)Let K be a field with characteristic different from 2 and let S be a symbol algebra over K. We compute the symmetric powers of hyperbolic quadratic forms over K. Also, we compute the symmetric powers of the quadratic trace ... -
A review of '"I Remember Your Name in the Night. Thinking about death" by Donagh O'Shea'
(The Furrow, 1997)Those who are already familiar with Fr O'Shea's reflections in books such as Take nothing for the journey (1990) will be delighted to hear from him again. His own personal journey has continued and he invites the reader ... -
A review of '"Clashing Symbols. An Introduction to Faith-and-Culture" by Michael Paul Gallagher'
(The Furrow, 1997)This book, its subject matter, and the manner in which it is handled, is clearly the work of someone of considerable scholarship, with a keen sense of mission. It is a book written not to provide information 'for the sake ...
