Mutual impedance of nonplanar-skew sinusoidal dipoles
The mutual impedance of nonplanar-skew sinusoidal dipoles is presented as a summation of several exponential integrals with complex arguments. Mathematical models are developed to show the near-zone field of the sinusoidal dipole. The mutual impedance of coupled dipoles is expressed as the sum of four monopole-mobopole impedances to simplify the analysis procedure. The subroutines for solving the parameters of the dipoles are discussed
Set and Drift: The Perils of Paperless
In a document released in November 1997, Defense Reform Initiative: The Busi- ness Strategy for Defense in the 21st Century, then–Secretary of Defense William Cohen stated, “To carry out our defense strategy into the 21st century with military forces able to meet the challenges of the new era, there is no alternative to achieving fundamental reform in how the Defense Department conducts business.”1 One initiative spelled out in the document concerns how Defense Department business practices are related to the management of technical data supporting defense weapons systems
Biomarkers in graft versus host disease after allogeneic hematopoietic stem cell transplant
Hematopoietic stem cell transplant was developed as a curative therapy to treat onco-hematological diseases and recently indications for this therapy have expanded to include solid tumors, hemoglobinopathies and other genetic diseases and disorders. Two major types of hematopoietic stem cell transplant have been developed. Autologous transplants aim to deliver a massive dose of radiation and/or chemotherapy that is capable of ablating the hematopoietic stem cells in the bone marrow. The patient is then "rescued" from this lethal dose of treatment by an infusion of their own hematopoietic stem cells. Allogeneic transplants are designed to either functionally replace a cell class, or an enzyme or biological function absent in the patient, or to consolidate a remission in a onco-hematological disease via the graft-versus-tumor effect . Two of the largest causes of non-relapse mortality from an allogeneic hematopoietic stem cell transplant are acute and chronic graft-versus-host disease, in which immune cells derived from the graft recognize normal host tissue as foreign and attack these tissues. A host of biomarkers for acute graft versus host disease have been identified, but there is almost none for chronic graft versus host disease. Herein, a methodology to discover and validate a biomarker(s) for the most common organ system affected by chronic graft versus host disease is proposed
The Transfer of ‘International Best Practice’ in a Brazilian MNC: A Consideration of the Convergence and Contingency Perspectives
This study examines the transfer of a Brazilian MNC's HR model to its subsidiaries in the UK, Canada, Switzerland and Norway. It enquires where the model was sourced from, to what extent it bore a distinct Brazilian complexion, and whether it was adapted to meet the strictures of host institutional constraints and traditions. The paper uses these questions to address an important theoretical debate in the international business literature; that is, whether the pattern of diffusion of management practices within MNCs will lead to a convergence of practices across companies and countries à la the convergence perspective, or whether this is unlikely given the variety of social and political constraints limiting such a process as suggested by the contingency perspective. We find that the MNC imposed a unitary (US-sourced) model of HR ‘best practice’ on all of its subsidiaries. Thus our empirical findings support the convergence thesis. However, we argue that these outcomes are largely explained by relations of power and economic dependence; specifically, the co-existence of dominant-country (US) practices and a dominant sectoral firm operating in economically dependent regions. Where similar circumstances are replicated one might foresee convergence within sectors across countries, but otherwise pluralism and eclecticism between sectors and across countries might be the predominant pattern along the lines envisaged in the conceptualization of “converging divergences”

Some Aspects of Price Inflation in Ireland. ESRI General Research Series Paper No. 40, January 1968
In every country prices have risen sUbstantiaUy
since the end of the war. In Ireland, as in six other
European countries, consumer prices had almost
doubled between 1948 and 1965--see Table 2. Is
this situation of continuously rising prices in the
indefinite future a fact of life which must be accepted
and with which we must somehow cope, or does it
mean that a sudden, and possibly catastrophic, fall
in prices, like that of May 192o after World War I,
is to be anticipated? History generally has a way of
repeating itself and similarities are observable
between our times and others, but with much longer
time-lags between cause and effect in the more
recent period. One might hope that, as governments
nowadays have much greater control of their
economies than in the past, and with the development
of the social conscience, disastrous price falls
can be avoided or mitigated. It is only a hope, however
Certain Aspects of Non-Agricultural Unemployment in Ireland. General Research Series Paper No. 52, January 1970
In Ireland less attention is paid to the chronically
high Irish unemployment rate than the gravity of
the problem merits. Indeed, the reason it is more
or less tacitly tolerated may be its permanent
character. Also, unemployment has declined considerably
over the years. At the Census of Population
(CP) of April 1936 those out of work numbered
95,000; in April 1966 the number was
52,000 in a labour force which, comparatively, did
not change much. As regards non-agricultural
unemployment (NAU), with which we are solely
concerned here, numbers declined in the 30 years
from 69,000 to 42,000. Since the non-agricultural
employee labour force (employed and unemployed)
greatly increased, the decline in rates
(i.e. out of work as percentage of employee labour
force) is even more striking: from 12.2 per cent
to 6.3 per cent. In the next section we shall find
that the decline in rates was also very marked in
the post-war II period. No doubt the fact of the
decline, as well as the efforts (largely successful in
the economic sense)being made to develop industry
(and incidentally1 to create new jobs) has done
much to assuage the public conscience. We shall
see, however, that in Irish conditions, there is no
necessary connection between increased employment
and decline in unemployment at rates of
expansion of the economy prevailing in recent
years and we shall show why. As a consequence,
it would appear that, to cope with the problem of
high unemployment, more must be done than expanding the economy. Unemployment must be
regarded as a specific social problem, almost as
if it were isolated from economic development.
Employment and unemployment are not one
problem but two
