Bricks & Mortar: Tax Policy Swings To Those Who Rent Homes, Tom Dunne

Articles

A major change in Ireland in recent years has been the rapid fall in home ownership, down from 75pc of households in 2006 to 70pc at present.

This brings Ireland more into line with home ownership rates in the US and UK, lower than those of southern Europe but higher than the prosperous economies of northern Europe where long-term renting is very common.

In the public mind, however, this lower level of owner occupancy is seen as temporary and symptomatic of a distressed economy where buyers have difficulty obtaining mortgages and in any event are content to stand off a …

Dual Orientation Of The Outer Membrane Lipoprotein P6 Of Nontypeable Haemophilus Influenzae, Lea V. Michel, Joy Snyder, Rachel Schmidt, Jennnifer Milillo, Kyle Grimaldi, Breanna Kalmeta, M. Nadeem Khan, Sharad Sharma, Leslie Kate Wright, Michael E. Pichichero

Articles

The majority of outer membrane (OM) lipoproteins in Gram-negative bacteria are tethered to the membrane via an attached lipid moiety and oriented facing in toward the periplasmic space; a few lipoproteins have been shown to be surface exposed. The outer membrane lipoprotein P6 from the Gram-negative pathogenic bacterium nontypeable Haemophilus influenzae (NTHi) is surface exposed and a leading vaccine candidate for prevention of NTHi infections. However, we recently found that P6 is not a transmembrane protein as previously thought (L. V. Michel, B. Kalmeta, M. McCreary, J. Snyder, P. Craig, M. E. Pichichero, Vaccine 29:1624–1627, 2011). Here we pursued studies …

Integrated Project Delivery is a rapidly developing approach to Design and Construction.This approach uses business structures, new technologies, and newly developing practices to collaboratively utilise the talents and contributions of all participants in the Design and Construction process.This project replicated this approach by creating a collaborative project between the School of Construction and the School of Real Estate and Construction Economics. The term “collaborative learning” refers to a method of delivery in which students at various performance levels work together in small groups towards a common goal. The students were responsible for one another’s learning as well as their own. …

Cereal Grain Combustion In Domestic Boilers, Andrew Keppel, John Finnan, Bernard Rice, Philip Owende, Kevin Macdonnell

Articles

This study compared the combustion characteristics and the combustion behaviour of oats, barley, triticale and wheat to that of wood pellets. Sustained grain combustion in domestic boilers was feasible but problematic, the main impediment being clinker formation with ash agglomeration. Clinker formation was lowest for oats which burned easily with fewer operational problems. Triticale displayed reasonably good combustion characteristics and also ignited easily. In contrast, barley and wheat proved difficult to ignite while barley combustion was prone to self-extinguish. Thermal and combustion efficiency and heat output were considerably higher at a grain moisture content of 15% compared to a moisture …

Environmental Consequences Of A Power Plant Shut-Down: A Three-Dimensional Water Quality Model Of Dublin Bay, Zeinab Bedri, Michael Bruen, Aodh Dowley, Barthelomew Masterson

Articles

A hydro-environmental model is used to investigate the effect of cessation of thermal discharges from a power plant on the bathing water quality of Dublin Bay. Before closing down, cooling water from the plant was mixed with sewage effluent prior to its discharge, creating a warmer, less-saline buoyant pollutant plume that adversely affects the water quality of Dublin Bay. The model, calibrated to data from the period prior to the power-plant shut-down (Scenario 1), assessed the water quality following its shut-down under two scenarios; (i) Scenario 2: continued abstraction of water to dilute sewage effluents before discharge, and (ii) Scenario …

Novel Dielectric Loaded Plasmonic Waveguide For Tight-Confined Hybrid Plasmon Mode, Youqiao Ma, Gerald Farrell, Yuliya Semenova, Hauping Chan, Hongzhou Zhang, Qiang Wu

Articles

In this paper a novel metal-dielectric waveguide structure is proposed to support hybrid long range surface plasmon polaritons (LRSPPs) with a highly confined mode field. The simulation results showed that our proposed structure has better mode confinement and propagation length compared to that of conventional dielectric-loaded surface plasmon polaritons (DLSPPs) waveguides. This structure offers greater flexibility for the design of SPPs waveguides by altering the trade-off between mode confinement and propagation length. The proposed structure has significant potential for application in highly integrated photonic circuits.

From Citizen Suits To Conservation Easements: The Increasing Private Role In Public Permit Enforcement, Jessica Owley

Articles

The past 40 years have seen an increase in the involvement of private actors in environmental law. One of the best-known (and arguably best-loved) methods for public involvement is the citizen suit. This popular method of public enforcement of environmental permits (among other things) has been joined by the use of conservation easements. Conservation easements are increasingly used to meet permit mitigation requirements. When private nonprofits hold these exacted conservation easements, they assume the role of permit enforcers. It is their job to ensure that conservation easement terms are complied with, giving them oversight and control over one of the …

Enhancement Of The Phytochemical And Fibre Content Of Beef-Patties With Himanthalia Elongata Seaweed, Sabrina Cox, Nissreen Abu-Ghannam

Articles

The effect of adding Himanthalia elongata seaweed (10 - 40% w/w) as a source of antioxidants and dietary fibre on physical, chemical, microbial and sensory traits of cooked beef patties was studied throughout chilled storage. Patties with seaweed showed reduced cooking losses and were nearly 50% more tender as compared to patties without seaweed. Microbiological counts and lipid oxidation were significantly lower in patties containing seaweed (P < 0.05), by day 30 of storage there was no bacterial growth in samples with ≥ 20% seaweed and lipid oxidation levels were low (0.61 mg malondialdehyde/kg of sample). Seaweed incorporation significantly increased the dietary fibre (1.64 g per 100 g fw in 40% seaweed-patties), total phenolic content (up to 28.11 mg GAE/100 g fw) and DPPH radical scavenging activity (up to 52.32%) of patties compared to the control. Sensory analysis indicated that the seaweed-patties were accepted by consumers in terms of aroma, appearance, texture and taste. Patties containing 40% seaweed were rated highest in terms of overall acceptability, most likely due to improvement in texture and mouthfeel. Addition of seaweed in the formulation of beef patties leads to the enhancement of the nutritional and technological quality together with an acceptable sensory quality.

Incorporation Of Himanthalia Elongata Seaweed To Enhance The Phytochemical Content Of Breadsticks Using Response Surface Methodology (Rsm), Sabrina Cox, Nissreen Abu-Ghannam

Articles

Optimization of incorporating seaweed into breadsticks was carried out using response surface methodology (RSM). Ten formulations of breadsticks were processed by varying concentrations of seaweed (X₁ = 5 to 15% of overall flour concentration) and white flour (X₂ = 10 to 30% of overall flour concentration) using a central composite design. The remaining flour concentrations were comprised of wholemeal flour. Predicted models were found to be significant (P < 0.05) for total phenolic content (TPC), DPPH radical scavenging activity, texture and color. Predicted values for each of the responses were in good agreement with the experimental values. Seaweed concentration had most significant effect on phytochemical constituents of the breadsticks with TPC and DPPH activity maximized when 17.07% H. elongata was incorporated into the flour (P < 0.05). An acceptable edible texture and color of breadsticks was also achieved at this concentration. Multiple response optimization demonstrated that phytochemical content of H. elongata breadsticks may be maximized with dried seaweed and white flour concentrations of 17.07 and 21.89%, respectively, in the …

Raman Spectroscopic Analysis Of Human Skin Tissue Sections Ex-Vivo: Evaluation Of The Effects Of Tissue Processing And Dewaxing, Syed Mehmood Ali, Franck Bonnier, Ali Tfayli, Helen Lambkin, Kathleen Flynn, Vincent Mcdonagh, Claragh Healy, Thomas Lee, Fiona Lyng, Hugh Byrne

Articles

Raman spectroscopy coupled with K-means clustering analysis (KMCA) is employed to elucidate the biochemical structure of human skin tissue sections, and the effects of tissue processing. Both hand and thigh sections of human cadavers were analysed in their unprocessed and formalin fixed paraffin processed (FFPP) and subsequently dewaxed forms. In unprocessed sections, KMCA reveals clear differentiation of the stratum corneum, intermediate underlying epithelium and dermal layers for sections from both anatomical sites. The stratum corneum is seen to be relatively rich in lipidic content; the spectrum of the subjacent layers is strongly influenced by the presence of melanin, while that …

The Economics Of Fuel Management: Wildfire, Invasive Plants, And The Dynamics Of Sagebrush Rangelands In The Western United States, Michael H. Taylor, Kimberly Rollins, Mimako Kobayashi, Robin J. Tausch

Articles

In this article we develop a simulation model to evaluate the economic efficiency of fuel treatments and apply it to two sagebrush ecosystems in the Great Basin of the western United States: the Wyoming Sagebrush Steppe and Mountain Big Sagebrush ecosystems. These ecosystems face the two most prominent concerns in sagebrush ecosystems relative to wildfire: annual grass invasion and native conifer expansion. Our model simulates long-run wildfire suppression costs with and without fuel treatments explicitly incorporating ecological dynamics, stochastic wildfire, uncertain fuel treatment success, and ecological thresholds. Our results indicate that, on the basis of wildfire suppression costs savings, fuel …

Isolation And Partial Characterization Of Bioactive Fucoxanthin From Himanthalia Elongata Brown Seaweed: A Tlc-Based Approach, Gaurav Rajauria, Nissreen Abu-Ghannam

Articles

Seaweeds are important sources of carotenoids, and numerous studies have shown the beneficial effects of these pigments on human health. In the present study, Himanthalia elongata brown seaweed was extracted with a mixture of low polarity solvents, and the crude extract was separated using analytical thin-layer chromatography (TLC).The separated compounds were tested for their potential antioxidant capacity and antimicrobial activity against Listeria monocytogenes bacteria using TLC bioautography approach. For bio-autography, the coloured band on TLC chromatogram was visualized after spraying with DPPH and triphenyltetrazolium chloride reagents which screen antioxidant and antimicrobial compounds, respectively, and only one active compound was screened …

Using Pcr To Target Misconceptions About Gene Expression, Leslie Kate Wright, Dina L. Newman

Articles

We present a PCR-based laboratory exercise that can be used with first- or second-year biology students to help overcome common misconceptions about gene expression. Biology students typically do not have a clear understanding of the difference between genes (DNA) and gene expression (mRNA/protein) and often believe that genes exist in an organism or cell only when they are expressed. This laboratory exercise allows students to carry out a PCR-based experiment designed to challenge their misunderstanding of the difference between genes and gene expression. Students first transform E. coli with an inducible GFP gene containing plasmid and observe induced and un-induced …

Rationalizing Creativity—Rationalizing Public Service: Is Scheduling Management Fit For The Digital Era?, Ann-Marie Murray

Articles

In public broadcast organizations across Europe, scheduling has been transformed from a marginal, administrative activity to a highly strategic management tool (Hellman, 1999; Hujanen, 2002; Meier, 2003;Ytreberg, 2000) Ellis (2000)described it as “the locus of power in television,” organizing production and managing budgets (p. 26). The role of scheduling in public broadcast organizations today reflects the demands of increasing competition and political pressure for efficiency and accountability. However, new challenges have emerged in the transition from public service broadcasting to public service media (PSM). PSM providers must redefine their mission for the digital era and find …

Recently at IMMA there was a panel discussion on the topic of “Art Academy+Knowing” in the context of the I Know You exhibition which is takign place there at the moment, but also within the wider sector there seems to be a sequence of alliances between the tradition Art College and third level education. The movement towards more integration of the stand alone Art Colleges and third level education is high on the agenda …

Agency Self-Insulation Under Presidential Review, Jennifer Nou

Articles

Agencies possess enormous regulatory discretion. This discretion allows executive branch agencies in particular to insulate their decisions from presidential review by raising the costs of such review. They can do so, for example, through variations in policymaking form, cost-benefit analysis quality, timing strategies, and institutional coalition-building. This Article seeks to help shift the literature's focus on courtcentered agency behavior to consider instead the role of the President under current executive orders. Specifically, the Article marshals public-choice insights to offer an analytic framework for what it calls agency self-insulation under presidential review, illustrates the phenomenon, and assesses some normative implications. The …

Well-Being Analysis Vs. Cost-Benefit Analysis, Jonathan Masur, John Bronsteen, Christopher Buccafusco

Articles

Cost-benefit analysis (CBA) is the primary tool used by policymakers to inform administrative decisionmaking. Yet its methodology of converting preferences (often hypothetical ones) into dollar figures, then using those dollar figures as proxies for quality of life, creates significant systemic errors. These problems have been lamented by many scholars, and recent calls have gone out from world leaders and prominent economists to find an alternative analytical device that would measure quality of life more directly. This Article proposes well-being analysis (WBA) as that alternative. Relying on data from studies in the field of hedonic psychology that track people's actual experience …

Secure Access Control For Health Information Sharing Systems, Suhair Alshehri, Rajendra K. Raj

Articles

The 2009 Health Information Technology for Economic and Clinical Health Act (HITECH) encourages healthcare providers to share information to improve healthcare quality at reduced cost. Such information sharing, however, raises security and privacy concerns that require appropriate access control mechanisms to ensure Health Insurance Portability and Accountability Act (HIPAA) compliance. Current approaches such as Role-Based Access Control (RBAC) and its variants, and newer approaches such as Attribute-Based Access Control (ABAC) are inadequate. RBAC provides simple administration of access control and user permission review, but demands complex initial role engineering and makes access control inflexible. ABAC, on the other hand, simplifies …

Professional Skills Portfolio For A Progressive Engineering Education, Dermot Mcgarthy, David Kennedy

Articles

At the 2013 launch of the return to work scheme, “Springboard” in Dublin, it was stated that employers were seeking staff with enhanced language, presentation, communication, coping, and team-working skills. Graduates without these skills were finding it more difficult to gain permanent employment and were more likely to find themselves out of work unless they developed these skills. Enhancing personal development skills in education requires a revision of existing programmes. Not alone will these skills open new doors of opportunity for those who have lost their jobs during the recession, but should help sustain them going forward. The education of …
