Making Sense Of The Data On Ireland's Inward Fdi, Clare O'Mahony, Frank Barry Jan 2005

Making Sense Of The Data On Ireland's Inward Fdi, Clare O'Mahony, Frank Barry

Articles

Ireland, in employment terms, is the most FDI-intensive economy in the EU. International comparisons of trends and levels of FDI intensity are usually based on balance-of-payments data however, and the international data series on Ireland’s inward FDI tell hugely conflicting stories. Such series are published by the IMF, UNCTAD, OECD and Eurostat (with data generally provided either by the CSO or the IDA), while data on US FDI in Ireland are published by the US Bureau of Economic Analysis. The present paper documents these conflicting stories and searches for any underlying consistency through analysis of the items that the various …

Structure Property Relationships In Organic Conjugated Systems, Luke O'Neill, Patrick Lynch, Mary Mcnamara Jan 2005

Structure Property Relationships In Organic Conjugated Systems, Luke O'Neill, Patrick Lynch, Mary Mcnamara

Articles

A series of π conjugated oligomers were studied by absorption and photoluminescence spectroscopy. A linear relationship between the positioning of the absorption and photoluminescence maxima plotted against inverse conjugation length is observed. The relationships are in good agreement with the simple particle in a box method, one of the earliest descriptions of the properties of one-dimensional organic molecules. In addition to the electronic transition energies, it was observed that the Stokes shift also exhibited a well-defined relationship with increasing conjugation length, implying a correlation between the electron-vibrational coupling and chain length. This correlation is further examined using Raman spectroscopy, whereby …

Structural Property Relationships In Conjugated Polymers, Patrick Lynch, Luke O'Neill, J. Whelan, Mary Mcnamara, Hugh Byrne Jan 2005

Structural Property Relationships In Conjugated Polymers, Patrick Lynch, Luke O'Neill, J. Whelan, Mary Mcnamara, Hugh Byrne

Articles

The synthesis of a series of PPV derivative polymers by the Wittig-Horner reaction is described. The structure of each polymer is varied and the effects of these variations on the optical properties is explored. The effects of alkyloxy side chains is observed between the PPV derivatives Poly(-p-phenylvinylene-co-2,5-bis-octyloxy phenylvinylene.) PPV-OPV and Poly (para-2,5-bis-(n-octyloxy)-phenylvinylene) POPV. The phenyl units of the soluble PPV derivative POPV are replaced by alternate naphthyl units in the polymer Poly(2,5-bis(n-octyloxy)-1,4-phenylene vinylene-1,5-bis(n-octyloxy)-2,6-naphthylene vinylene) POPN-ONV and then fully by naphthyl units in Poly(2,6-bis-(n-octyloxy)-1,5-NaphthyleneVinylene) PONV. The addition of alkyloxy sidechains served to red shift the fluorescence emission as expected. The systematic …

Capitalising On Culture: An Evaluation Of Culture-Led Urban Regeneration Policy, Luke Binns Jan 2005

Capitalising On Culture: An Evaluation Of Culture-Led Urban Regeneration Policy, Luke Binns

Articles

Municipal authorities throughout Western Europe are attempting to drive regeneration of their urban centres through policies designed to attract inward investment and tourism. In an attempt to woo these outside economic agents in, a variety of cultural consumption oriented policies have been developed and marketed. These include investment in hard cultural-infrastructure such as museums or art galleries, and in less physical aspects such as holding events like the European Capital of Culture. A polemical debate surrounds this use of cultural policy with a clearly economic agenda. This paper gives a brief synopsis of some culture-led regeneration models, addresses the validity …

Identification Of Fatty Acid Oxidation Disorder Patients With Lowered Acyl-Coa Thioesterase Activity In Human Skin Fibroblasts, Mary Hunt, Jos Ruiter, Petra Mooyer, Carlo W T Van Roermond, Rob Ofman, Lodewig Ijlst, Ronald J A Wanders Jan 2005

Identification Of Fatty Acid Oxidation Disorder Patients With Lowered Acyl-Coa Thioesterase Activity In Human Skin Fibroblasts, Mary Hunt, Jos Ruiter, Petra Mooyer, Carlo W T Van Roermond, Rob Ofman, Lodewig Ijlst, Ronald J A Wanders

Articles

Background: Acyl-CoA thioesterases are enzymes that hydrolyze acyl-CoAs to the free fatty acid and coenzyme A (CoASH). These enzymes have been identified in several cellular compartments and are thought to regulate intracellular levels of acyl-CoAs, free fatty acids and CoASH. However, to date no patients deficient in acyl-CoA thioesterases have been identified. Design: Acyl-CoA thioesterase activity was measured in human skin fibroblasts. Western blot analysis was used to determine Type-II acyl-CoA thioesterase protein levels in patients. Results: Activity was found in human fibroblasts with all saturated acyl-CoAs from C4:0- to C18:0-CoA, with highest activity detected with lauroyl-CoA and myristoyl-CoA (C12:0 …

Gene Therapy And Targeted Toxins For Glioma, James Curtin, Gwendalyn King, Marianela Candolfi, Kurt Kroeger, Pedro Lowenstein, Maria Castro Jan 2005

Gene Therapy And Targeted Toxins For Glioma, James Curtin, Gwendalyn King, Marianela Candolfi, Kurt Kroeger, Pedro Lowenstein, Maria Castro

Articles

The most common primary brain tumor in adults is glioblastoma. These tumors are highly invasive and aggressive with a mean survival time of nine to twelve months from diagnosis to death. Current treatment modalities are unable to significantly prolong survival in patients diagnosed with glioblastoma. As such, glioma is an attractive target for developing novel therapeutic approaches utilizing gene therapy. This review will examine the available preclinical models for glioma including xenographs, syngeneic and genetic models. Several promising therapeutic targets are currently being pursued in pre-clinical investigations. These targets will be reviewed by mechanism of action, i.e., conditional cytotoxic, targeted …

Real-Time Reverse Transcription Pcr For Detection And Quantitative Analysis Of Equine Influenza Virus, Michelle Quinlivan, Eugene Dempsey, Fergus Ryan, Sean Atkins, Ann Cullinane

Articles

Equine influenza is a cause of epizootic respiratory disease of the equine. The detection of equine influenza virus using real-time Light Cycler reverse transcription (RT)-PCR technology was evaluated over two influenza seasons with the analysis of 171 samples submitted for viral respiratory disease. Increased sensitivity was found in overall viral detection with this system compared to Directigen Flu A and virus isolation, which were 40% and 23%, respectively, that of the RT-PCR. The assay was also evaluated as a viable replacement for the more traditional methods of quantifying equine influenza virus, 50% egg infectious dose and 50% tissue culture infectious …

Judicial Impediments To Legislating Equality For Same-Sex Couples In The European Union, Bruce Carolan Jan 2005

Judicial Impediments To Legislating Equality For Same-Sex Couples In The European Union, Bruce Carolan

Articles

In the United States, the state and federal courts often has been the first port of call for activists hoping to advance the cause of same-sex couples. State courts, in particular, have ruled on occasion that guarantees of equal rights or due process contained in state constitutions require recognition of same-sex marriage or civil unions. These court decisions, in turn, have sparked a legislative backlash. Legislators and voters have rejected these court decisions by amending state constitutions to limit the rights of same-sex couples. The European Union represents, in some ways, the mirror image of the United States experience. The …

Optimization Of Impedance Bandwidth For The Printed Rectangular Monopole Antenna, Matthias John, Max Ammann Jan 2005

Optimization Of Impedance Bandwidth For The Printed Rectangular Monopole Antenna, Matthias John, Max Ammann

Articles

This paper describes a printed rectangular-plate monopole fed by microstrip line. The effect of varying the plate width, feed-gap height, and feedline width on the impedance bandwidth is examined. It is shown that for a fixed ground-plane size, that optimization of these parameters can yield an impedance bandwidth ratio of 4.3:1, without using any broadbanding techniques.

What Is An Entrepreneurial Team?, Thomas Cooney

Articles

It is arguable that despite the romantic notion of the entrepreneur as a lone hero, the reality is that successful entrepreneurs either built teams about them or were part of a team throughout. For example, when one considers the success of Apple Computers, the name of Steven Jobs immediately springs to mind.

Risk, Rents, And Regressivity: Why The United States Needs Both An Income Tax And A Vat, Reuven S. Avi-Yonah Dec 2004

Risk, Rents, And Regressivity: Why The United States Needs Both An Income Tax And A Vat, Reuven S. Avi-Yonah

Articles

In this article, Prof. Avi-Yonah argues that the legal academic debate about fundamental tax reform from 1974 onward has been skewed by the assumption that a consumption tax must replace the income tax. He addresses three of the major issue in recent writings on the income/consumption tax debate, and shows how none of the arguments in favor of the consumption tax are conclusive. Avi-Yonah also addresses the various consumption tax proposals that have been made and shows that they are all deficient in comparison with a VAT, as well as failing to achieve the goals of an income tax. Finally, …

Isolation Of Cancer Stem Cells From Adult Glioblastoma Multiforme, Xianpeng Yuan, James Curtin, Yizhi Xiong, Gentao Liu, Sebastian Waschsmann-Hogiu, Daniel Farkas, Keith Black, John Yu Dec 2004

Isolation Of Cancer Stem Cells From Adult Glioblastoma Multiforme, Xianpeng Yuan, James Curtin, Yizhi Xiong, Gentao Liu, Sebastian Waschsmann-Hogiu, Daniel Farkas, Keith Black, John Yu

Articles

Glioblastoma multiforme (GBM) is the most common adult primary brain tumor and is comprised of a heterogeneous population of cells. It is unclear which cells within the tumor mass are responsible for tumor initiation and maintenance. In this study, we report that brain tumor stem cells can be identified from adult GBMs. These tumor stem cells form neurospheres, possess the capacity for self-renewal, express genes associated with neural stem cells (NSCs), generate daughter cells of different phenotypes from one mother cell, and differentiate into the phenotypically diverse populations of cells similar to those present in the initial GBM. Having a …

Regulatory Taxings, Eduardo Peñalver Dec 2004

Regulatory Taxings, Eduardo Peñalver

Articles

The tension between the Supreme Court's expansive reading of the Takings Clause and the state's virtually limitless power to tax has been repeatedly noted, but has received little systematic exploration. Although some scholars, most notably Richard Epstein, have used the tension between takings law and taxes to argue against the legitimacy of taxation as it is presently practiced, such an approach has failed to gain a significant following. Instead, the broad legal consensus is that legislatures effectively have unlimited authority to impose tax burdens. Nevertheless, this Article demonstrates that every attempt to formulate a "Reconciling Theory," a theory that would …

Articles

We present Sloan Digital Sky Survey and United States Naval Observatory observations of the V1647 Ori protostar and surrounding field near NGC 2068. V1647 Ori, the likely driving source for HH 23, brightened significantly in November 2003. Analysis of SDSS imaging acquired in November 1998 and February 2002 during the quiescent state, recent USNO photometry, and published 2MASS and Gemini data shows that the color changes associated with brightening suggest an EXor outburst rather than a simple dust clearing event.

The Defined Contribution Paradigm, Edward A. Zelinsky Dec 2004

The Defined Contribution Paradigm, Edward A. Zelinsky

Articles

Pension cognoscenti have frequently remarked on the stagnation of defined benefit pensions and the concomitant rise of defined contribution plans. I suggest that, over the last generation, something even more fundamental has occurred, something that can justly be called a paradigm shift. Americans today primarily conceive of and implement retirement savings in the form of individual accounts. Such accounts have become primary instruments of public policy, not just for retirement savings, but increasingly for health care and education as well.

Satirical Legal Studies: From The Legists To The Lizard, Peter Goodrich Dec 2004

Satirical Legal Studies: From The Legists To The Lizard, Peter Goodrich

Articles

Satirical legal studies utilize humor and ridicule to critique the pretensions and follies of the legal profession and academia, transcending traditional boundaries and challenging established hierarchies. By blending satire with legal critique, this genre exposes the social and political dimensions of law, advocating for inclusivity and radical change. Despite facing backlash, satire remains a vital tool in legal discourse, offering fresh perspectives and engaging forms that keep legal studies dynamic and relevant.

Articles

We use HST/ACS imaging of 100 early-type galaxies in the ACS Virgo Cluster Survey to investigate the nature of diffuse star clusters (DSCs). Compared to globular clusters (GCs), these star clusters have moderately low luminosities (MV > −8) and a broad distribution of sizes (3 < rh < 30 pc), but they are principally characterized by their low mean surface brightnesses which can be more than three magnitudes fainter than a typical GC (µg > 20 mag arcsec−2). The median colors of diffuse star cluster systems are red, 1.1 < g − z < 1.6, which is redder than metal-rich GCs and often as red as the galaxy itself. Most DSC systems thus have mean ages older than 5 Gyr or else have super-solar metallicities implying that diffuse star clusters are likely to be long-lived, surviving for significant fraction of a Hubble time. We find that 12 galaxies in our sample contain a significant excess of diffuse star cluster candidates. Nine of them are morphologically classified as lenticulars (S0s), and five of them visibly contain dust. We also find a substantial population of DSCs in the halo of the giant elliptical M49, associated with the companion galaxy VCC 1199. Most DSC systems appear to be both aligned with the galaxy light and associated with galactic disks, but at the same time many lenticular galaxies do not host substantial DSC populations, and environment and clustercentric radius do not appear to be good predictors of their existence. Diffuse star clusters in our sample share similar characteristics to those identified in other nearby lenticular, spiral, and dwarf galaxies. Unlike luminous GCs, whose sizes are constant with luminiosity, DSCs are bounded at the bright end by an envelope of nearly constant surface brightness. We suggest that populations of diffuse star clusters preferentially form, survive, and coevolve with galactic disks. Their properties are broadly consistent with those of merged star cluster complexes, and we note that despite being 3–5 magnitudes brighter than DSCs, ultra-compact dwarfs have similar surface brightnesses. The closest Galactic analogs to the DSCs are the old open clusters. We suggest that if a diffuse star cluster population did exist in the disk of the Milky Way, it would be very difficult to find.

How Well Can People Use Different Color Attributes?, Hongqin Zhang, Ethan Montag Nov 2004

How Well Can People Use Different Color Attributes?, Hongqin Zhang, Ethan Montag

Articles

Two psychophysical experiments were conducted to analyze the role of color attributes in simple tasks involving color matching and discrimination. In Experiment I observers made color matches using three different adjustment control methods. The results showed that the Lightness, Chroma, Hue (LCH) and the Lightness, redness/greenness, blueness/yellowness ({L, r/g, y/b}) adjustment controls elicited significantly better performance than the display RGB controls in terms of both accuracy and time, but were not significantly different from each other. Expert observers performed significantly better than naive observers in terms of accuracy. Experiment II was a replication and extension of Melgosa, et al.’s experiment …

Supermassive Black Holes In Active Galactic Nuclei. Ii. Calibration Of The Black Hole Mass-Velocity Dispersion Relationship For Active Galactic Nuclei, Christopher A. Onken, Laura Ferrarese, David Merritt, Bradley M. Peterson, Richard W. Pogge, Marianne Vestergaard, Amri Wandel Nov 2004

Supermassive Black Holes In Active Galactic Nuclei. Ii. Calibration Of The Black Hole Mass-Velocity Dispersion Relationship For Active Galactic Nuclei, Christopher A. Onken, Laura Ferrarese, David Merritt, Bradley M. Peterson, Richard W. Pogge, Marianne Vestergaard, Amri Wandel

Articles

We calibrate reverberation-based black hole masses in active galactic nuclei (AGNs) by using the correlation between black hole mass, MBH, and bulge/spheroid stellar velocity dispersion, σ[sigma]∗. We use new measurements of σ[sigma]∗ for 6 AGNs and published velocity dispersions for 10 others, in conjunction with improved reverberation mapping results, to determine the scaling factor required to bring reverberation-based black hole masses into agreement with the quiescent galaxy MBH–σ[sigma]∗ relationship. The scatter in the AGN BH masses is found to be less than a factor of 3. The current observational uncertainties preclude use of the scaling factor to discriminate between broad-line …

The ACS Virgo Cluster Survey is a large program to carry out multi-color imaging of 100 early-type members of the Virgo Cluster using the Advanced Camera for Surveys (ACS) on the Hubble Space Telescope. Deep F475W and F850LP images (≈ SDSS g and z) are being used to study the central regions of the program galaxies, their globular cluster systems, and the three-dimensional structure of Virgo itself. In this paper, we describe in detail the data reduction procedures used for the survey, including image registration, drizzling strategies, the computation of weight images, object detection, the identification of globular cluster candidates, …

The Federalist Dimension Of Regulatory Takings Jurisprudence, Stewart E. Sterk Nov 2004

The Federalist Dimension Of Regulatory Takings Jurisprudence, Stewart E. Sterk

Articles

Conventional wisdom teaches that the Supreme Court's takings doctrine is a muddle. Appearances, however, are deceiving. The "property" protected by the Takings Clause is defined not by a single sovereign, but by the legislative enactments and judicial pronouncements of fifty separate states. As a result, federalism concerns - underappreciated in the takings literature - do and should play an important role in shaping the Court's takings doctrine. In particular, these concerns make it inappropriate for the Court to use the Takings Clause as a vehicle for articulating a comprehensive theory of the limits on government power to regulate land. This …
