Infrared Surface Brightness Analysis of Galaxies in Compact Groups
Images of 7 Compact groups of galaxies (CG) were obtained using the 2.1m
telescope in San Pedro Martir (B.C. Mexico) equipped with the NIR camera
CAMILA. The NIR images trace the mass of the galaxies, through the oldest and
more evolved stellar populations. The goal of this project is to search for
evidence of morphological perturbations correlated with the level of activity
(AGN or star formation) of the galaxies. We find that the level of perturbation
is well correlated with activity observed in optical spectrocopy (Coziol et al.
2004). Evidence for perturbations decreases from more active groups to less
active groups, confirming the classification. Our analysis suggests that
galaxies in more active groups are undergoing important transformations due to
interaction and merging and that the whole groups is on a merger path. Galaxies
in less active CG have gone through similar processes in the recent past and
are either in a final merging phase or in equilibrium due to a more massive
halo of dark matter.Comment: 2 pages, 1 figure, Proc. ESO Workshop "Groups of galaxies in the

Planned construction as a leading indicator of commercial real estate price appreciation
Includes bibliographical references.I analyze the viability of planned construction as a leading indicator to commercial price appreciation through application of fundamental economic principles, and linear regression. My experience as a commercial real estate appraiser has brought me to suspect that the commercial real estate market is a thinly traded market where information asymmetries are common, and exploitation opportunities may exist. The potential leading indicators that I analyze are the Architectural Billing Index (ABI), building permits, housing starts, and the combination of all three. The regression analysis results in strong correlations between each leading indicator and commercial appreciation. The strong correlations lead me to believe that the current commercial real estate market is not a perfectly competitive market, and arbitrage opportunities may currently exist for investors who are able to analyze the market using leading indicators, and quickly enter or exit the market.B.S.

Roman Apollo and kindred deities
At this point it may be well to review the Roman
cult of Apollo as we have found it, and its development
throughout the Roman period, comparing it briefly with the
cult as it came to them from the Greeks. As a background
to this study we shall bear in mind the fact that the Greeks
being closer to their :Eastern origins than the Romans, their
religion often shows a tendency to mysticism and to a childlike reverence which rather avoids than seeks complete explanation or application.We have seen that, when at the height of its
popularity and influence in Rome, the cult of Apollo was an
important part of the state religion. It was in fact at
no time, except perhaps for less than fifty years before
our records begin, entirely outside the national religion,
and it was never to any extent a matter of personal belief
or private emotion. This in itself, however, does not
mean that it lacked either sincerity or influence. If we
would find a parallel, the feelings ,of the Romans about
their official religious ceremonies and institutions, and
therefore about almost all their religion, must have been
similar to ours as we stand with the crowd to sing a solemn
traditional hymn at a time of national emergency, or listen
to the speech of an archbishop or king which ends with a
sort of patriarchal blessing. In both cases the religious act represents the lowest common multiple of the spiritual
experience of a people. But there is an instructive
difference. In the case of the Romans, there were not many
people of very high spiritual development and in fact the
loftier souls did not rise very far above the general level.
Likewise, the general level being low, few would fall far
below it. This would be true, at any rate, until Christianity
arrived to upset the balance, Under such conditions it was
comparatively easy to find and use the common factor, and
only too easy for religion to be stabilized at the most convenient level. Polytheism has also great advantages as the
type of a national religion, because deities and cults can
be retained to meet the needs of those who fall short of
or surpass the general level of spiritual development.We have here some of the reasons why the religions
of ancient Greece and Rome seldom received the impetus and
challenge of religious leaders, reformers or "prophets ".
This has been remarked by A.B. Drachmann ( Atheism in
Pagan Antiquity) who, incidentally, in his study of atheism
has revealed rather more about religion than irreligion.
He writes (p. 15): "But what is characteristic of the
whole process is the fact that it went on without breaks
or sudden bounds. Nowhere in ancient religion, as far as
we can trace it, did a powerful religious personality strike
in with a radical transformation, with a direct rejection
of old ideas and dogmatic accentuation of new ones."As we have found, however, in tracing the history
of the Roman cult of Apollo, there was, especially in that
cult, a continual demand for such a religious leader. We
have called him an "Apolline prophet" and have tried to indicate some of those who from time to time, for a smaller
or larger section of Apollo's worshippers, fulfilled this
function. It is probably in the context of this hope that
we should place such literature as Virgil's Fourth Eclogue.
This poem has recently been discussed by Professor H.J.
Rose, in "The Eclogues of Vergil" where he rejects the
suggestion of Norden and others that the "child" is merely
allegorical. The grounds of this rejection are that the
concluding lines of the poem seem to refer vividly to a
human mother, and that the personification of a period of
time does not occur elsewhere in classical literature.
The latter objection is certainly very strong in relation
to the argument of Norden which is quoted (H.J. Rose, op,
cit. p. 208 -9). The former, however, is applicable to
Prof. Rose's own theory almost as much as to that of Norden.
For Prof. Rose suggests that the father of the "wonder -child"
is Octavian, who, though not actually a father when the poem
was written, is regarded by the poet as inaugurating a
Golden Age for the continuance of which he would certainly
require an heir. The mother of the child, however, would
as yet be unknown, though she would not be the abstract
figure required by the other theory.We would therefore suggest that the child in the
Fourth Eclogue of Virgil is, primarily, the Apolline prophet
whom we have traced through about seven centuries. In so
far as Virgil envisaged the earthly parentage of this child
it may be readily admitted that he thought of Octavian,
to whom might be attributed the very possibility of this
Golden Age. The address to Follio may, as has often been
suggested, refer to the hope of a rapprochement between
Octavian and Antony during his time of office, and so to
a further union of Apolline and Dionysiac religion. Most
of the other features of the poem, and its general stru.ture,
require no further explanation than that given by ProfeBsor
Rose (op.cit. p. 167ff.) who would connect it with rhetorical
or poetical forms of birthday or marriage tributes.In the Roman cult of Apollo, therefore, we have
traced the continuation of the search for an Apolline prophet,
and also, the development among the Romans of the idea of
prophecy and of the providential government of the world.
Through the Sibylline Books and the ideas therewith associated, the Romans grew to recognise not merely the idea of
Spontaneous and casual prophecy, but of a controlled and
controlling "fatum" in relation to which their own efforts
had their place.In the cult of Apollo Medicus and Aesculapius we
have discerned some of the Romans' own progress in the
understanding of health and healing. It has also become
clear that they did not receive in this respect all that
the Greek civilisation could offer, and that we have been
the poorer for what they could not transmit. The influence,
however, of the traditions of religious healing which the
Romans were able to accept has been traced asfaras the
Christian era, and some estimate of its contribution tt
Christian thought and action has been attempted.It would appear that, in general, the history
of Apolline religion was that of a constant striving to
express in practice a spiritual ideal, or to find someone
capable of such expression. Most, however, of Roman, if
not of Greek, religion was in essentials the reverse of
this, namely an attempt to spiritualize practical expedients.
If Christianity finally proved to have a greater appeal in
the ancient world than the religion of Apollo, it was
mainly because it seemed able to provide this long -sought
expression of spiritual values. Apolline religion pre-
:pared the way, however feebly, for this development in the
Hellenistic and Roman world, but, as we have tried to show,
there were two conflicting lines of influence operative
upon the development of the Roman cult of Apollo. These
we have called the Etruscan and the Greek spirit in religion,
realising, however, that they cannot be completely dis-
:tinguished at any period. The influence and effects which
we are concerned to trace here, and those which have proved
their validity in relation to subsequent religious progress,
belong mainly to the heritage derived by the Romans from
the Greek world.It seems that the spiritual quest which we have
detected in Apolline religion is, in some form, an essential
preparation for the acceptance of Christianity. In so far as later generations have missed such necessary
preparation, their understanding of Christian doctrine
has been the weaker. .ë:aui the time of the early Christian
Fathers, the Church has also borrowed freely from the other
side of Roman religious tradition which we have traced ul-
:timately to Etruria. ':There this has taken place, it has
often resulted in obscuring, perhaps only temporarily, the
broader, freer enlightenment associated with Apollo. To
that extent have we, like many former generations, been
deprived of one of the fundamental conditions of a higher
spiritual development, a condition which, with our present
meagre spiritual equipment, it is difficult otherwise
to attain
William, an Englishman (1919) and the Collapse of Cicely Hamilton’s Pre-war Meliorism
William, an Englishman is a novel written in a tent near the French front by a ‘non-combatant’: the wartime volunteer nurse, postal overseer and theatrical performer Cicely Hamilton. A well-known playwright, actress, suffrage militant, polemical essayist before the conflict, Hamilton, nowadays largely overlooked, performed here a post-mortem exploration of some influential attitudes which were transformed by the experience of war. Coming from someone who had been particularly active on the British radical scene, the text’s denunciation of social progress, pacifism, internationalism, and even votes for women as naive ideals may appear unexpected. She drew from long personal knowledge as well as contemporary documentation to write a novel that, while not untouched by sympathy for her characters, is often brutal. The collapse of Hamilton’s previous political optimism, her (self-ironical) criticism of any belief in the perfectibility of human beings may come as a shock even today. But those familiar with Senlis (1917) might have anticipated Hamilton’s sombre 1919 text. ‘Modern warfare is so monstrous, allengrossing and complex, that there is a sense, and a very real sense, in which hardly a civilian stands outside it; where the strife is to the death with an equal opponent the non-combatant ceases to exist.’ The abuse and strategic bombing of civilian populations, the collapse of former distinctions between combatants and non-combatants, the mobilization of almost entire nations were early on denounced by the writer. ‘No modern nation could fight for its life with its men in uniform only; it must mobilize, nominally or not, every class of its population for a struggle, too great and too deadly for the combatant to carry alone.’ (Senlis 34) Her discerning eye read the Great War for what it was: a conflict which was leaving no domain of social, economic and political life unsullied, a total war.info:eu-repo/semantics/acceptedVersio
Comparative Study of Asymmetry Origin of Galaxies in Different Environments. II. Near-Infrared observations
In this second paper of two analyses, we present near-infrared (NIR)
morphological and asymmetry studies performed in sample of 92 galaxies found in
different density environments: galaxies in Compact Groups (HCGs), Isolated
Pairs of Galaxies (KPGs), and Isolated Galaxies (KIGs). Both studies have
proved useful for identifying the effect of interactions on galaxies. In the
NIR, the properties of the galaxies in HCGs, KPGs, and KIGs are more similar
than they are in the optical. This is because the NIR band traces the older
stellar populations, which formed earlier and are more relaxed than the younger
populations. However, we found asymmetries related to interactions in both KPG
and HCG samples. In HCGs, the fraction of asymmetric galaxies is even higher
than what we found in the optical. In the KPGs the interactions look like very
recent events, while in the HCGs galaxies are more morphologically evolved and
show properties suggesting they suffered more frequent interactions. The key
difference seems to be the absence of star formation in the HCGs; while
interactions produce intense star formation in the KPGs, we do not see this
effect in the HCGs. This is consistent with the dry merger hypothesis (Coziol &
Plauchu-Frayn 2007); the interaction between galaxies in compact groups, (CGs),
is happening without the presence of gas. If the gas was spent in stellar
formation (to build the bulge of the numerous early-type galaxies), then the
HCGs possibly started interacting sometime before the KPGs. On the other hand,
the dry interaction condition in CGs suggests that the galaxies are on merging
orbits, and consequently such system cannot be that much older either.
