Risks And Safety On The Internet: Comparing Brazilian And European Children, Alexander Barbosa, Brian O'Neill, Cristina Ponte, Simões Simões, Tatiana Jereissati

Articles

A child’s home and school are the most frequently reported locations of internet use in Brazil: 60% of Brazilian children aged 9 to 16 who used the internet claimed to access it from home, and 42% from school, whereas in Europe this proportion is 87% for home access and 63% for schools.

However, when it comes to accessing the network from publicly sponsored internet access centres such as Local Area Network (LAN) Houses or cybercafés, the value in Brazil is considerably higher when compared to Europe, 35% against 12% respectively. Access from public libraries is far more popular in Europe …

Making An Impact: New Directions For Arts And Humanities Research, Ellen Hazelkorn

Articles

The severity of the global economic crisis has put the spotlight firmly on measuring academic and research performance and productivity, and assessing its contribution, value, impact and benefit. While traditionally, research output and impact was measured by peer-publications and citations, there is increased emphasis on a “market-driven approach”, which favours the bio-, medical and technological sciences, and helped reinforce a disciplinary hierarchy in which arts and humanities research (A&HR) has struggled for attention. This article charts the changing policy environment across Ireland, the Netherlands and Norway. It draws on evidence from the HERAVALUE project which studied how different stakeholders value …

Electric Field Standing Wave Effects In Ft-Ir Transflection Spectra Of Biological Tissue Sections: Simulated Models Of Experimental Variability, Tomasz P. Wrobel, Barbara Wajnchold, Hugh Byrne, Malgorzata Baranska

Articles

The so-called electric field standing wave effect (EFSW) has recently been demonstrated to significantly distort FT-IR spectra acquired in a transflection mode, both experimentally and in simulated models, bringing into question the appropriateness of the technique for sample characterization, particularly in the field of spectroscopy of biological materials. The predicted effects are most notable in the regime where the sample thickness is comparable to the source wavelength. In this work, the model is extended to sample thicknesses more representative of biological tissue sections and to include typical experimental factors which are demonstrated to reduce the predicted effects. These include integration …

Mid-Infrared Raman Sources Using Spontaneous Raman Scattering In Germanium Core Optical Fibers, Pengfei Wang, Christy Charlton O'Mahony, Timothy Lee, Rand Ismaeel, Thomas Hawkins, Yuliya Semenova, Lin Bo, Qiang Wu, Colette Mcdonagh, Gerald Farrell, John Ballato, Gilberto Brambilla

Articles

Mid-infrared Raman sources based on spontaneous Raman scattering have been demonstrated in a 15-lm diameter glass-clad crystalline germanium optical fiber and in a germanium-wire. A quantum cascade laser was used as pump at a wavelength of 5.62 lm. Because of their ultra-high optical nonlinearities and extremely broad transparency window, germanium core fibers offer the possibility of fabricating compact and efficient mid-infrared sources.

Efficient Red-Shifted Dispersive Wave In A Photonic Crystal Fiber For Widely Tunable Mid-Infrared Wavelength Generation, Jinhui Yuan, Xinzhu Sang, Qiang Wu, Chongxiu Yu, K.R. Wang, B.B. Yan, X.W. Shen, Y. Han, G.Y. Zhou, Yuliya Semenova, Gerald Farrell, L.T. How

Articles

Red-shifted dispersive waves (DWs) at the mid-infrared wavelengths are generated for the first time by pumping a photonic crystal fiber (PCF) with two zero dispersion wavelengths specially designed and fabricated in our lab, and the central wavelength of the soliton generated lies on the negative slope of the PCF dispersion profile. The experimental result shows that the conversion efficiency η of red-shifted DWs increases from 5℅ to 15℅ as the input power changes from 100 to 300 mW with the pump wavelength of 810 nm. By adjusting both the pump wavelength and power, the tunable range of the wavelength generated …

Learning From Learning Groups, Mike Murphy, S. M. Chance, Gavin Duffy, Brian Bowe

Articles

Collaborative learning is a key, and complementary, component of student-centred enquiry-based pedagogy. Today, many educators understand that students learn effectively when working together with their peers to construct new knowledge. Many teachers are working to help their students develop such ability. Teachers do this to help students better understand the relevance of new content, connect new ideas into existing frameworks of understanding, and construct new neurological pathways and connect synapses in their brains. In addition, group learning has been shown to increase students’ critical thinking skills, creativity, collaborative behaviours, understanding of ethics, and the like. In the literature, attention has …

A Highly Efficient Tio2-Xcx Nano-Heterojunction Photocatalyst For Visible-Light Induced Antibacterial Applications, Vinodkumar Etacheri, Michael Seery, Stephen Hinder, Georg Michlits, Suresh Pillai

Articles

Visible-light-induced antibacterial activity of carbon-doped anatase-brookite titania nano-heterojunction photocatalysts are reported for the first time. These heterostructures were prepared using a novel low temperature (100 °C) non-hydrothermal low power microwave (300 W) assisted method. Formation of interband C 2p states was found to be responsible for the band gap narrowing of the carbon doped heterojunctions. The most active photocatalyst obtained after 60 minutes of microwave irradiation exhibits a 2-fold higher visible-light induced photocatalytic activity in contrast to the standard commercial photocatalyst Evonik-Degussa P-25. Staphylococcus aureus inactivation rate constant for carbon-doped nano-heterojunctions and the standard photocatalyst was 0.0023 and -0.0081 min …

Derivation Of A Fuzzy National Phosphorus Export Model Using 84 Irish Catchments, Ahmed Nasr, Michael Bruen

Articles

Implementation of appropriate management strategies to mitigate diffuse phosphorus (P) pollution at the catchment scale is vitally important for the sustainable development of water resources in Ireland. An important element in the process of implementing such strategies is the prediction of their impacts on P concentrations in a catchment using a reliable mathematical model. In this study, a state-of-the-art adaptive neuro-fuzzy inference system (ANFIS) has been used to develop a new national P model capable of estimating average annual ortho-P concentrations at un-gauged catchments. Data from 84 catchments dominated by diffuse P pollution were used in developing and testing the …

Drift Detection Using Uncertainty Distribution Divergence, Patrick Lindstrom, Brian Mac Namee, Sarah Jane Delany

Articles

Data generated from naturally occurring processes tends to be non-stationary. For example, seasonal and gradual changes in climate data and sudden changes in financial data. In machine learning the degradation in classifier performance due to such changes in the data is known as concept drift and there are many approaches to detecting and handling it.

Most approaches to detecting concept drift, however, make the assumption that true classes for test examples will be available at no cost shortly after classification and base the detection of concept drift on measures relying on these labels. The high labelling cost in many domains …

Spectral Multiplicity Of Selfadjoint Schrodinger Operators On Star-Graphs With Standard Interface Conditions, Sergey Simonov, Harald Woracek

Articles

We analyze the singular spectrum of selfadjoint operators which arise from pasting a finite number of boundary relations with a standard interface condition. A model example for this situation is a Schroedinger operator on a star-shaped graph with continuity and Kirchhoff conditions at the interior vertex. We compute the multiplicity of the singular spectrum in terms of the spectral measures of the Weyl functions associated with the single (independently considered) boundary relations. This result is a generalization and refinement of Theorem of I.S. Kac.

Extreme Wave Events In Ireland: 14 680 Bp–2012, Laura Cooke, John M. Dudley, Frédéric Dias

Articles

The island of Ireland is battered by waves from all sides, most ferociously on the west coast as the first port of call for waves travelling across the Atlantic Ocean. However, when discussing ocean events relevant to the nation of Ire- land, one must actually consider its significantly larger designated continental shelf, which is one of the largest seabed territories in Europe. With this expanded definition, it is not surprising that Ireland has been subject to many oceanic events which could be designated as “extreme”; in this paper we present what we believe to be the first catalogue of such …

Achieving A Holistic View Of The Life Cycle Performance Of Existing Dwellings, Albert Famuyibo, Aidan Duffy, P. Strachan

Articles

Models which fully evaluate the life cycle energy and greenhouse gas (GHG) emissions of national housing stocks are not reported in literature. Capturing a holistic view of energy and emissions of the residential sector is an important process that can lead to a more effective policy making. This paper presents a methodology which evaluates the life cycle energy and GHG emissions of retrofitting housing stocks considering all life cycle stages and incorporating, to the greatest extent possible, all upstream inputs.

To achieve this, we developed a hybrid model of the existing Irish housing stock, comprising a process-based approach supplemented by …

The Conventional Option, Gregory Koger, Sergio J. Campos

Articles

The filibuster in the United States Senate effectively imposes a supermajority vote requirement to pass any legislation. Both supporters and critics of the filibuster agree that any filibuster reform would require extraordinary measures. In contrast to this consensus, this Article describes a method we call the "conventional option," which allows the filibuster to be reformed by a simple majority of senators at any time using ordinary Senate procedures. As we show below, a majority of senators using the conventional option (1) cannot be filibustered; (2) can act on any day the Senate is in session (not just at the beginning …

Loss Of Mef2d Expression Inhibits Differentiation And Contributes To Oncogenesis In Rhabdomyosarcoma Cells., Meiling Zhang, Jamie Truscott, Judith Davie

Articles

BACKGROUND: Rhabdomyosarcoma (RMS) is a highly malignant pediatric cancer that is the most common form of soft tissue tumors in children. RMS cells have many features of skeletal muscle cells, yet do not differentiate. Thus, our studies have focused on the defects present in these cells that block myogenesis.

METHODS: Protein and RNA analysis identified the loss of MEF2D in RMS cells. MEF2D was expressed in RD and RH30 cells by transient transfection and selection of stable cell lines, respectively, to demonstrate the rescue of muscle differentiation observed. A combination of techniques such as proliferation assays, scratch assays and soft …

Additional Quantitative Trait Loci And Candidate Genes For Seed Isoflavone Content In Soybean, M Akond, Bazelle Richard, Bobby Ragin, Harmin Herrera, Umerah Kaodi, Cevdet Akbay, Stella K. Kantartzi, Victor Njiti, Abdelali Barakat, Khalid Meksem, David A. Lightfoot, My Abdelmajid Kassem

Articles

Seed isoflavone content of soybean (Glycine max L. Merr.) is a trait of moderate heritablity and an ideal target for marker selection. To date over 20 QTL have been identified underlying this trait among seven populations. The objectives of this study were to identify additional QTL and candidate genes controlling isoflavone content in a set of recombinant inbred line (RIL) populations of soybean grown in two different seasons. Variations of isoflavones namely daidzein, glycitein and genistein contents over two growing seasons and locations suggests that isoflavones are influenced by both genes and environments. Six QTL were identified on five …

Barriers And Solutions To Recruitment Strategies Of Students Into Post-Secondary Agricultural Education Programs: A Focus Group Approach, Jennifer Calvin, Seburn L. Pense

Articles

This qualitative study utilized focus group interviews of secondary Illinois agricultural education teachers to investigate the continuing problem of student recruitment into teacher preparation pro-grams of agricultural education. Using signal theory, image theory and person-organization fit theory, the researchers identified five themes relating to recruitment issues: time, the economy, family, technology and image. Each theme is described through the words of the participants and solutions are suggested for improving recruitment.

Practical Use Of Nitrogen Gas As A Method For Insect Control In Herbaria, Miriam Kritzer Van Zant, Donald Ugent, David A. Lightfoot

Articles

Herbaria are libraries of dried mounted plants used for plant identification, research vouchers and teaching. Herbarium specimens are subject to damage from insects, fungi and bacteria, and must be protected by treatments that kill damaging organisms. Naphthalene, the most common chemical currently used in herbaria, is a class C carcinogen and potential allergen. The aim was to develop an affordable alternative to treatment with persistent hazardous toxins for maintaining dried herbarium specimens. The new method uses ambient temperature nitrogen gas and widely available, valved, nylon, oxygen barrier bags. Nitrogen gas treatment has been shown to be less expensive than freezer …
