Self-Chem: Student Engagement In Learning Through Flipped Chemistry Lectures, Michael K. Seery Jan 2014

Self-Chem: Student Engagement In Learning Through Flipped Chemistry Lectures, Michael K. Seery

Teaching Fellowships

This project introduces the idea of “flipped lecturing” to a group of second year students. The aim of flipped lecturing is to provide much of the “content delivery” of lecture in advance, so that the lecture hour can be devoted to more in-depth discussion, problem solving, etc. As well as development of the material, a formal evaluation is being conducted. Fifty-one students from year 2 Chemical Thermodynamics module took part in this study. Students were provided with online lectures in advance of their lectures. Along with each online lecture, students were given a handout to work through as they watched …

The Development, Implementation And Initial Evaluation Of Tailorable Resource Packs For Multimedia Based "Assessments For Learning", Barry Ryan Jan 2014

The Development, Implementation And Initial Evaluation Of Tailorable Resource Packs For Multimedia Based "Assessments For Learning", Barry Ryan

Teaching Fellowships

In this project a suite of tailorable teaching and learning resources were created, implemented and evaluated. These resources focused on the assessment for learning model, adopting the constructivist approach to learning. Here, the student builds their knowledge, and deepens their understanding, as they complete their assessment. The resources were designed to aid academic adoption, and student implementation, of this model of assessment. The assessment outputs created using these resources were digital videos and network concept maps. The tailorable resources provided a structured and scaffolded environment for both the academic and student to explore this learning space. Both students and academic …

Bake For The Border, Bake For The Border

Irish Food Blogs

I love to cook, bake and eat. The latter is my downfall. My interest began when I was a tiny girl. My late Mam was a great cook and was always baking and cooking us great food. She loved watching Darina Allen on television when we were children growing up in the ’80s in rural Ireland and I always watched too curled up beside her on the sofa. I would leaf through her cook books and circle the things I wanted her to make for me. Later on in life, when I went to university in Edinburgh, I would call …

A Silence That Wants To Be Heard: Suburban Korean American Students In Dialogue With Invisibility, Dawan Coombs, Hye-Young Park, Bob Fecho Jan 2014

A Silence That Wants To Be Heard: Suburban Korean American Students In Dialogue With Invisibility, Dawan Coombs, Hye-Young Park, Bob Fecho

Faculty Publications

Korean American students experience invisibility and silence as their culture and presence remain outwardly invisible in the mainstream culture of US high schools. This is further exacerbated by the silent response of the dominant population of the school towards these issues. Yet, to an extent, Korean American students find a sense of comfort within that invisibility; less visibility allows more silence and thus more privacy. This qualitative in-depth interview study focuses on developing understandings of Korean American students’ perceptions and negotiations of education in suburban American schools, specifically through the perceptions of two Korean American female students. When viewed through …

A Reflective Report On Values Informing Professional Practice In Educating The Educators, Roisin Donnelly Jan 2014

A Reflective Report On Values Informing Professional Practice In Educating The Educators, Roisin Donnelly

Papers, presentations and other resources

While a significant body of work on the practice of academic development exists, research on academic developers (those charged with supporting the education of academic staff in higher education) as professionals is limited, and few have explored the profession from the perspective of academic developers themselves [21]. Specifically, this reflective report begins to address the question of how best to prepare and support current and future academic developers for their ambiguous and complex roles and their need to function within the changing environment of higher education institutions. Since embarking on a role in an Irish Higher Education Institution in 1999 …

Dielectric Barrier Discharge Atmospheric Cold Plasma For Inactivation Of Pseudomonas Aeruginosa Biofilms, Dana Ziuzina, Sonal Patil, Patrick J. Cullen, Daniela Boehm, Paula Bourke Jan 2014

Dielectric Barrier Discharge Atmospheric Cold Plasma For Inactivation Of Pseudomonas Aeruginosa Biofilms, Dana Ziuzina, Sonal Patil, Patrick J. Cullen, Daniela Boehm, Paula Bourke

Articles

In recent years, atmospheric cold plasma (ACP) has been widely investigated for potential application as an alternative decontamination technology in biomedical and healthcare sectors. In this study, the antimicrobial efficacy of ACP against Pseudomonas aeruginosa biofilms was investigated. The 48-h biofilms were treated inside sealed polypropylene containers with a high-voltage dielectric barrier discharge (DBD) ACP (80 kVRMS) and subsequently stored for 24 h at room temperature. Treatment for 60 s by either the direct or indirect mode of ACP exposure (inside or outside plasma discharge, respectively) reduced bacterial populations by an average of 5.4 log cycles from an initial 6.6 …

Play Hard, Work Harder. Alternative Reality Game And Scenario Based Assessments For Learning., Barry Ryan Jan 2014

Play Hard, Work Harder. Alternative Reality Game And Scenario Based Assessments For Learning., Barry Ryan

Articles

In this paper, an evaluative case study is detailed as an example of alternative reality game and scenario based assessments for learning. This pedagogic approach is evaluated and recommendations for practice offered. Integrating technology into the assessment process, and final student product, influenced the chosen pedagogy. The use of technology permitted this assessment approach to be adopted for a medium sized (n=40) student cohort. The use of wikis, eportfolios and digital reflective diaries were central to creating a learning environment that centralised the student and allowed them to construct and create their knowledge through scaffolded alternative reality games and scenarios. …

Safety Risk Registers: Challenges And Guidance, Nora Balfe, Maria Chiara Leva, Brian Mcaleer, Michael Rocke Jan 2014

Safety Risk Registers: Challenges And Guidance, Nora Balfe, Maria Chiara Leva, Brian Mcaleer, Michael Rocke

Articles

A risk database, or risk register, is a central tool for organisations to use to monitor and reduce risks, both those identified during initial safety assessments and those emerging during operations (Whipple and Pitblado, 2010). The risk register should contain all analysed risks and should prioritise the areas that require managerial attention. When populated with information on each risk, including risk ranking, the risk register can be analysed to present the risk profile for different aspects of the organisation (Filippin and Dreher, 2004). When reviewed and updated over time, it can also be analysed to present trends within the risk …

Using An Iconic Story To Bring Communities Together To Develop A Tourism Experience, Denise O'Leary, Mary Rose Stafford Jan 2014

Using An Iconic Story To Bring Communities Together To Develop A Tourism Experience, Denise O'Leary, Mary Rose Stafford

Conference papers

Tourism destination governance is concerned with the development and management of a destination; who is involved and how they are involved. Although the term governance was traditionally associated with politics and government structures it has become more broadly applied in recent years to also describe more grassroots approaches involving various community stakeholders such as individual business owners in tourism product and service provision, business owners in other sectors, community leaders and community residents Morrison (2013). Turbulence in the market has forced the tourism industry to move away from centralised, government-led, hierarchical type of governance towards more participatory approaches where stakeholders …

Introduction: Tickling The Palate. Gastronomy In Irish Literature And Culture, Eamon Maher, Máirtín Mac Con Iomaire Jan 2014

Introduction: Tickling The Palate. Gastronomy In Irish Literature And Culture, Eamon Maher, Máirtín Mac Con Iomaire

Books/Chapters

There has been a gradual but noticeable growth in scholarship concerning food globally, particularly in the last decade. One of the longest running and most inf luential forces behind this phenomenon is the Oxford Symposium on Food and Cookery (1981–present) which was originally founded and co-chaired by Alan Davidson, pre-eminent food historian, diplomat, and author of The Oxford Companion to Food, and Dr Theodore Zeldin, the celebrated social historian of France. This spawned a dedicated publishing house, Prospect Books, which published the conference proceedings and also the journal Petits Propos Culinaires (PPC), now approaching its 100th issue.

Tunetracker: Tensions In The Surveillance Of Traditional Music, Bryan Duggan, Norman M. Su Jan 2014

Tunetracker: Tensions In The Surveillance Of Traditional Music, Bryan Duggan, Norman M. Su

Conference papers

We describe the design and deployment of the first system ever to dynamically track and publish records of folk music playing. TuneTracker is a software system that has been, at time of writing, deployed at a pub in Dublin, Ireland for five months. It captures, stores, and posts the names of tunes played in Irish traditional music sessions on a public website. This paper makes two contributions: (1) drawing from a two year ethnographic study of trad musicians, it details the design and development of a system to track and publish traditional musicians’ practices while respecting the ethos of tradition, …

Robustness And Prediction Accuracy Of Machine Learning For Objective Visual Quality Assessment, Andrew Hines, Paul Kendrick, Adriaan Barri, Manish Narwaria, Judith A. Redi Jan 2014

Robustness And Prediction Accuracy Of Machine Learning For Objective Visual Quality Assessment, Andrew Hines, Paul Kendrick, Adriaan Barri, Manish Narwaria, Judith A. Redi

Conference papers

Machine Learning (ML) is a powerful tool to support the development of objective visual quality assessment metrics, serving as a substitute model for the perceptual mechanisms acting in visual quality appreciation. Nevertheless, the reliability of ML-based techniques within objective quality assessment metrics is often questioned. In this study, the robustness of ML in supporting objective quality assessment is investigated, specifically when the feature set adopted for prediction is suboptimal. A Principal Component Regression based algorithm and a Feed Forward Neural Network are compared when pooling the Structural Similarity Index (SSIM) features perturbed with noise. The neural network adapts better with …

Building A Database Of Political Speech Does Culture Matter In Charisma Annotations?, Andrew Hines, Ailbhe Cullen, Naomi Harte

Conference papers

For both individual politicians and political parties the in- ternet has become a vital tool for self-promotion and the distribution of ideas. The rise of streaming has enabled po- litical debates and speeches to reach global audiences. In this paper, we explore the nature of charisma in political speech, with a view to automatic detection. To this end, we have collected a new database of political speech from YouTube and other on-line resources. Annotation is per- formed both by native listeners, and Amazon Mechanical Turk (AMT) workers. Detailed analysis shows that both la- bel sets are equally reliable. The results …

Perceived Audio Quality For Streaming Stereo Music, Andrew Hines, Eoin Gillen, Naomi Harte, Damien Kelly, Jan Skoglund, Anil Kokaram Jan 2014

Perceived Audio Quality For Streaming Stereo Music, Andrew Hines, Eoin Gillen, Naomi Harte, Damien Kelly, Jan Skoglund, Anil Kokaram

Conference papers

Users of audio-visual streaming services expect an ever increasing quality of experience. Channel bandwidth remains a bottleneck commonly addressed with lossy compression schemes for both the video and audio streams. Anecdotal evidence suggests a strongly perceived link between bit rate and quality. This paper presents three audio quality listening experiments using the ITU MUSHRA methodology to assess a number of audio codecs typically used by streaming services. They were assessed for a range of bit rates using three presentation modes: consumer and studio qual- ity headphones and loudspeakers. Our results indicate that with consumer quality headphones, listeners were not differentiating …

Insulin Acutely Improves Mitochondrial Function Of Rat And Human Skeletal Muscle By Increasing Coupling Efficiency Of Oxidative Phosphorylation., Raid B. Nisr, Charles Affourtit Jan 2014

Insulin Acutely Improves Mitochondrial Function Of Rat And Human Skeletal Muscle By Increasing Coupling Efficiency Of Oxidative Phosphorylation., Raid B. Nisr, Charles Affourtit

School of Biomedical Sciences

Insulin is essential for the regulation of fuel metabolism and triggers the uptake of glucose by skeletal muscle. The imported glucose is either stored or broken down, as insulin stimulates glycogenesis and ATP synthesis. The mechanism by which ATP production is increased is incompletely understood at present and, generally, relatively little functional information is available on the effect of insulin on mitochondrial function. In this paper we have exploited extracellular flux technology to investigate insulin effects on the bioenergetics of rat (L6) and human skeletal muscle myoblasts and myotubes. We demonstrate that a 20-min insulin exposure significantly increases (i) the …

Renting In Ireland, Lorcan Sirr Jan 2014

Renting In Ireland, Lorcan Sirr

Books/Book Chapters

As part of the overall housing sector, renting has seen a considerable increase in the first 14 years of the twenty-first century. Numbers renting are now similar to those of the 1950s, when Ireland was a very different place economically and socially. Today renting is driven by forces ranging from necessity to choice to ongoing urbanisation: it is becoming the tenure of preference for many, while remaining the tenure for others with no choice. Governing legislation, providers of rental accommodation and the various rental sectors’ economic value and importance are all in flux. The traditional divide between state-supplied social housing …

A Calderón Preconditioner For The Electric Field Integral Equation With Layered Medium Green's Function, Yongpin P. Chen, Sheng Sun, Lijun Jiang, Weng Cho Chew Jan 2014

A Calderón Preconditioner For The Electric Field Integral Equation With Layered Medium Green's Function, Yongpin P. Chen, Sheng Sun, Lijun Jiang, Weng Cho Chew

Electrical and Computer Engineering Faculty Research & Creative Works

A Calderón preconditioner is developed for the analysis of electromagnetic scattering of perfect electrically conducting (PEC) objects embedded in a layered medium. The electric field integral equation (EFIE) is formulated with the kernel of layered medium Green's function to account for the effects from the multilayered background. The Calderón projector is derived based on the general source-field relationship and the extinction theorem for inhomogeneous environment in electromagnetic theory. The Calderón identities can be naturally deduced based on this projector, which is then leveraged to precondition the EFIE with layered kernel. An alternative implementation is then proposed to make the implementation …

A Rigorous Approach For The Radiated Emission Characterization Based On The Spherical Magnetic Field Scanning, Ping Li, Li (Lijun) Jun Jiang Jan 2014

A Rigorous Approach For The Radiated Emission Characterization Based On The Spherical Magnetic Field Scanning, Ping Li, Li (Lijun) Jun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

Electromagnetic radiated emissions from antennas, printed circuit boards (PCBs), and electronic devices are becoming increasingly critical to today's IC electromagnetic compatibility and interference properties. In this paper, a rigorous characterization approach is proposed. The electromagnetic field sampling over a spherical testing surface is applied to obtain the radiated magnetic field of the device under test (DUT) placed at the center of the sampling region. Using the dyadic Green's function (DGF) and Huygens' principle, the transformation from the sampled spherical tangential field to the far field is directly computed without resorting to the conventional inverse algorithm. The DGF considers the existence …

A Hybrid Time-Domain Discontinuous Galerkin-Boundary Integral Method For Electromagnetic Scattering Analysis, Ping Li, Yifei Shi, Li (Lijun) Jun Jiang, Hakan Baǧci Jan 2014

A Hybrid Time-Domain Discontinuous Galerkin-Boundary Integral Method For Electromagnetic Scattering Analysis, Ping Li, Yifei Shi, Li (Lijun) Jun Jiang, Hakan Baǧci

Electrical and Computer Engineering Faculty Research & Creative Works

A scheme hybridizing discontinuous Galerkin time-domain (DGTD) and time-domain boundary integral (TDBI) methods for accurately analyzing transient electromagnetic scattering is proposed. Radiation condition is enforced using the numerical flux on the truncation boundary. The fields required by the flux are computed using the TDBI from equivalent currents introduced on a Huygens' surface enclosing the scatterer. The hybrid DGTDBI ensures that the radiation condition is mathematically exact and the resulting computation domain is as small as possible since the truncation boundary conforms to scatterer's shape and is located very close to its surface. Locally truncated domains can also be defined around …

Thermal-Electromagnetic Analysis Of Infrared Antennas, Edward C. Kinzel, Brian Slovick, James Ginn, Brian Lail, Glenn Boreman Jan 2014

Thermal-Electromagnetic Analysis Of Infrared Antennas, Edward C. Kinzel, Brian Slovick, James Ginn, Brian Lail, Glenn Boreman

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Antenna-coupled Metal-Oxide-Metal (MOM) diodes have been demonstrated for sensing and proposed for energy harvesting at THz, infrared, and even visible frequencies. The design of the antenna allows engineering of the response of the device with respect to polarization, wavelength and angle of incidence. The classic understanding of the antenna coupled MOM diode is that the electric field generated by the antenna causes electrons to tunnel through the barrier oxide. This is supported by the fact that when the oxide separates metals with different work functions, a properly polarized field can produce an asymmetric tunnel current under zero bias. Losses in …

The Soft-Feedback Isi Canceller-Based Turbo Equalizer For Multilevel Modulations, Huang Lou, Chengshan Xiao Jan 2014

The Soft-Feedback Isi Canceller-Based Turbo Equalizer For Multilevel Modulations, Huang Lou, Chengshan Xiao

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, we investigate the soft-feedback equalizer (SFE) proposed by Lopes et al. for multilevel modulations. The SFE is based on InterSymbol interference canceller structure and is compared to both soft-decision feedback turbo equalizer (SDFE) and the exact solution of MMSE linear equalizer (Exact-MMSE-LE) by means of EXIT chart analysis and BER simulations. Interesting results reveal that, for multilevel modulations, the SFE not only exhibits the same low complexity, low SNR threshold and fast convergence as SDFE but also reaches matched filter bound after a large number of iterations. © 2013 Springer Science + Business Media New York.

An Accurate Frame Error Rate Approximation Of Coded Diversity Systems With Non-Identical Diversity Branches, Gang Wang, Jingxian Wu, Yahong Rosa Zheng Jan 2014

An Accurate Frame Error Rate Approximation Of Coded Diversity Systems With Non-Identical Diversity Branches, Gang Wang, Jingxian Wu, Yahong Rosa Zheng

Electrical and Computer Engineering Faculty Research & Creative Works

This paper presents an accurate approximation of the frame error rate (FER) of coded wireless communication systems with receiver diversity, such as single-input multiple-output (SIMO) systems with maximum ratio combining (MRC) or hybrid automatic repeat request (HARQ) systems with Chase combining. The signals at different diversity branches experience independent but non-identically distributed Rayleigh fading. The FER approximation is obtained with a threshold-based method. Specifically, the threshold value, which is critical to the FER approximation accuracy, is modeled as a linear function of the frame length in the log-domain, with the slope and intercept of the linear function determined by the …

Responsive Classroom Ecologies: Supporting Student Inquiry And Rhetorical Awareness In College Writing Courses, Adrienne Jankens Jan 2014

Responsive Classroom Ecologies: Supporting Student Inquiry And Rhetorical Awareness In College Writing Courses, Adrienne Jankens

Wayne State University Dissertations

This dissertation describes and analyzes the work of a semester-long teacher research study of inquiry-based and reflective teaching and learning strategies and their impact on students' preparation for future learning. I explore relevant scholarship on knowledge transfer, classroom ecologies, and student agency to set the stage for a discussion of several pedagogical strategies implemented to support students' development of inquiry and responsible rhetorical agency. Data analysis highlights three major arguments: first, that alternative pedagogical approaches like an inquiry approach take careful classroom construction and explicit teacher feedback, though it may seem counterintuitive to the politics behind these progressive approaches, which …

Pathway Profiling Of Replicative And Induced Senescence, Maggie Purcell Jan 2014

Pathway Profiling Of Replicative And Induced Senescence, Maggie Purcell

Wayne State University Dissertations

Senescence is a permanent withdrawal from cell cycle that occurs naturally in cells in response to the shortening of telomeres. This natural "clock" serves to limit the number of cell divisions and therefore protects the cell from potentially carcinogenic mutations. However, senescence also occurs in response to external stresses to the cell, which is known as induced senescence. This study compares the mechanisms of natural senescence, a response to the shortening of telomeres during replication, with induced senescence by using various drugs to induce senescence: 5-aza-2-deoxycytidine (a demethylating agent), Adriamycin (a chemotherapeutic drug), and H2O2 (an agent causing oxidative stress). …

A Genealogy Of Ecological Rhetoric: Heraclitus, Bacon, Darwin And Huxley, Jared Grogan Jan 2014

A Genealogy Of Ecological Rhetoric: Heraclitus, Bacon, Darwin And Huxley, Jared Grogan

Wayne State University Dissertations

This dissertation is a genealogical study of historical intersections between rhetoric and ecology. Studying the works of Heraclitus, Francis Bacon, T.H. Huxley and Darwin as "bridge figures" in the history of rhetoric, science and ecological thought, I examine how their rhetorical theories and strategies (as discursive practices, performances and techniques) form a genealogy that bridges rhetorical and ecological theories and practices. My analysis studies their critical assessments and uses of rhetoric as it intersects with each figure's new investigations into natural philosophy, nature, and evolutionary biology, while drawing out relevant lessons for contemporary ecological and rhetorical thinkers. The main threads …
