Experimental Gasoline Markets, Cary A. Deck, Bart J. Wilson

Economics Faculty Articles and Research

Zone pricing in wholesale gasoline markets is a contentious topic in the public policy debate. With a controlled laboratory experiment, we investigate the competitive effects of zone pricing on consumers, retail stations, and refiners vis-à-vis the proposed policy prescription of uniform wholesale pricing to retailers. We also examine the issue of divorcement and the “rockets and feathers” phenomenon. The former is the legal restriction that refiners and retailers cannot be vertically integrated, and the latter is the perception that retail gasoline prices rise faster than they fall in response to random walk movements in the world price for oil.

Alcohol Use Among Adolescents, Malynda R. Zuck

Graduate Research Papers

Alcohol is the most frequently used drug among adolescents today. Alcohol use among adolescents has been linked to many probable consequences and risks including: motor vehicle crashes, risky sexual behavior and an increased risk for sexually transmitted diseases, suicide, poor physical and mental health, lower social competence, and decreases in school achievement (Brown et al., 2007; Diego, Field, & Sanders, 2003; Wallace & Fisher, 2006). Research has shown that the earlier an adolescent initiates with the use of alcohol, the more likely that person will experience alcohol dependence in his or her life, with the onset of dependence occurring quickly …

35 | Maresha Excavations Final Report Ii: Hellenistic Terracotta Figurines From The 1989–1996 Seasons, Adi Erlich, Amos Kloner

IAA Reports—Monograph Series of the Israel Antiquities Authority

This is the second volume in a series of final reports documenting the large-scale excavations at the site of Maresha, mainly in the Lower City, during the 1980s and 1990s. In the Hellenistic period, Maresha was an important and multi-cultural city. Hellenistic terracottas are a varied and widespread medium of Hellenistic art of a religious and cultic nature. The extensive repertoire presented here, mostly found in residential contexts during the excavations of the mid-1980s to 1996, opens a window onto the city’s culture, religion and daily life. It describes their typology as well as the production methods and techniques.

Demarcating The Right To Gather News: A Sequential Interpretation Of The First Amendment, Erik Ugland

College of Communication Faculty Research and Publications

The recent spate of cases in which reporters have been subpoenaed, fined, jailed, or otherwise disciplined has laid bare the divisions among the courts over the existence and scope of the “reporter’s privilege.” The cases have also exposed the doctrinal, historical, and theoretical infirmities of the broader law of newsgathering, which encompasses not only source relationships, but also rights of access to places and records, protections against civil and criminal liability for torts and crimes committed in the pursuit of news, and protections against government searches of newsrooms and phone records, among other things. Resolving these conflicts has grown more …

Development Of Teaching And Technology Integration: Focus On Pedagogy, Nancy Wentworth, Charles R. Graham, Tonya Tripp

Faculty Publications

The development, implementation, review, and subsequent revision of a capstone assignment during teacher education candidates’ field experience and the assignments-related rubric was based on research that points teacher education programs to give candidates experiences in rethinking their views of pedagogy as they integrate technology into the curriculum. The initial development of the rubric came as a result of requirements of national accrediting organizations for licensure programs to have performance assessments of their candidates. The review of the assignment by technology experts as well as education faculty showed a disconnect between the goals of the technology faculty and the mentors helping …

Diversification To Mitigate Expropriation In The Tobacco Industry, Messod D. Beneish, Ivo Ph. Jansen, Melissa F. Lewis-Western, Nathan V. Stuart

Faculty Publications

While it is well established that diversifying acquisitions by large, cash-rich firms destroy shareholder wealth, we document positive abnormal returns to such acquisitions in the tobacco industry. We show that these abnormal returns are associated with proxies for lower expected expropriation costs. Specifically, we show that wealth creation increases in the degree of domestic geographic expansion afforded by the acquisition (increasing tobacco firms’ influence in more political districts) and in the liquidity of tobacco firms’ assets (converting cash to harder-to-expropriate operating assets). We also show that the threat of expropriation constrains payments to shareholders before expropriation becomes certain in 1998.

Suicidal Ideation In College Students Varies Across Semesters: The Mediating Role Of Belongingness, Scott R. Braithwaite, Kimberly Van Orden, Tracy K. Witte, Lisa M. James, Yessenia Castro, Kathryn H. Gordon, Daniel L. Hollar, Thomas E. Joiner Jr.

Faculty Publications

The interpersonal–psychological theory of suicidal behavior (Joiner, 2005)proposes that the need to belong is fundamental; when met it can prevent suicide and when thwarted it can substantially increase the risk for suicide. We investigate one source of group-wide variation in belongingness among college students—changes in the social composition of college campuses across academic semesters—as an explanation for variation in suicidal ideation across the academic year.Our results indicate that in a sample of college students at a large southern state university (n=309), suicidal ideation varied across academic semesters, with high-est levels in summer compared to both spring and fall. Differences in …

John Zorn. The Gift; Songs From The Hermetic Theatre (2001). Chimeras; Masada Guitars (2003). Masada Recital; Magick (2004). Rituals (2005). Astronome; Masada Rock; Moonchild, Christian T. Asplund

Faculty Publications

Once the unruly upstart, John Zorn is now a MacArthur fellow, whose formidable catalog divides easily into early, middle, and late periods. The early period dates from the mid-1970s to the mid-1980s, when Zorn pioneered the practice of "comprovisation," a term used to describe "the making of new compositions from recordings of improvised material." Ultimately, Zorn's comprovisation blurs the lines between active listener and composer, since both create new works when they impose structure on found sonic material. His early structuralist-modernist approach to comprovisation produced esoteric, often severely pointillist music, and evolved into the game pieces of the late 1970s …

Effect Of Uva Fluence Rate On Indicators Of Oxidative Stress In Human Dermal Fibroblasts, James D. Hoerter, Christopher S. Ward, Kyle D. Bale, Admasu N. Gizachew, Rachelle Graham Rachelle Graham, Jaclyn Reynolds, Melanie E. Ward Melanie E. Ward, Chesca Choi, Jean-Leonard Kagabo, Michael Sauer, Tara Kuipers, Timothy Hotchkiss Timothy Hotchkiss, Nate Banner, Renee A. Chellson, Theresa Ohaeri, Langston Gant, Leah Vanderhill

Articles

During the course of a day human skin is exposed to solar UV radiation that fluctuates in fluence rate within the UVA (290-315 nm) and UVB (315-400 nm) spectrum. Variables affecting the fluence rate reaching skin cells include differences in UVA and UVB penetrating ability, presence or absence of sunscreens, atmospheric conditions, and season and geographical location where the exposure occurs. Our study determined the effect of UVA fluence rate in solar-simulated (SSR) and tanning-bed radiation (TBR) on four indicators of oxidative stress---protein oxidation, glutathione, heme oxygenase-1, and reactive oxygen species--in human dermal fibroblasts after receiving equivalent UVA and UVB …

Photochemical Studies Of Nutraceuticals In The Presence Of Cyclodextrins, Zlata Tofzikovskaya, Christine O'Connor, Mary Mcnamara

Conference Papers

The photostability studies of Folic acid and Menadione Sodium Bisulfite, also known as vitamin K3, were carried out in their aqueous solutions at room temperature. Solutions of Folic acid ( 4.8 x 10-5 M) and Menadione Sodium Bisulfite (4.0 x 10-4 M) were exposed to ultraviolet radiation at a wavelength of 365 nm. During exposure absorbance of both solutions was measured using a Perkin Elmer Lamda 900 UV/VIS/NIR Spectrometer. During the stability tests it was noted that addition of β Cyclodextrin (1:1 ratio) to aqueous solutions containing the vitamin slowed down the photodegradation process. The unique shape of Cyclodextrins allows …

Canadian Legal Ethics: Ready For The Twenty-First Century At Last, Adam M. Dodek

Osgoode Hall Law Journal

This article analyzes the transformation in the scholarship of legal ethics that has occurred in Canada over the last decade, and maps out an agenda for future research. The author attributes the recent growth of Canadian legal ethics as an academic discipline to a number of interacting factors: a response to external pressures, initiatives within the legal profession, changes in Canadian legal education, and the emergence of a new cadre of legal ethics scholars. This article chronicles the public history of legal ethics in Canada over the last decade and analyzes the first and second wave of scholarship in the …

Sustainable Professionalism, Trevor C. W. Farrow

Osgoode Hall Law Journal

This article challenges traditional visions of lawyering by building on current alternative narratives and articulating a new discourse of professionalism that is personally, politically, ethically, economically, and professionally sustainable. It is a discourse that makes space for lawyers' principles, interests, and life preferences by balancing them with other important interests (including, but not dominated by, those of clients). It is a discourse that seeks to make good on aspirational promises of equality, access to justice, and protecting the public interest. And it is a discourse that takes seriously obligations to, as well as benefits from, the culturally complicated makeup of …

The Public Interest, Professionalism, And Pro Bono Publico, Lorne Sossin

Osgoode Hall Law Journal

There is a clear public interest benefit for lawyers to ensure access to the rule of law, especially on the part of the vulnerable. This article seeks to show that the seemingly simple relationship between the legal profession and the public interest is in fact more complicated than it looks. Pro bono may be viewed from two perspectives-that of the lawyer and that of the client. From the perspective of the lawyer, the important question is whether there is ethical motivation to engage in pro bono. If, however, the perspective of the client is paramount, then meeting the client's needs …

Comparative In Vitro Cytotoxicity Study Of Silver Nanoparticle On Two Mammalian Cell Lines, Gordon Chambers, Sanchali Mukherjee, Alan Casey, Niall Ó Claonadh

Articles

In this study the cytotoxic effect of commercially available silver (Ag) nanoparticle was evaluated using human dermal and cervical cancer cell lines. Prior to the cellular studies a full particle size characterisation was carried out using Dynamic Light Scattering (DLS), Transmission Electron Microscopy and Scanning Electron Microscopy in distilled water and cell culture media. The Zeta Potential (ZP)associated with the Ag nanoparticle was also determined in order to assess its stability in the solutions and its possible interaction with the media. The DLS and ZP study have suggested interaction of Ag nanoparticles with the media, which can lead to secondary …

A System For Automatically Annotating Traditional Irish Music Field Recordings, Bryan Duggan, Brendan O'Shea, Padraig Cunningham

Conference papers

This paper presents MATT2 (Machine Annotation of Traditional Tunes). MATT2 is a novel system which can automatically annotate field recordings of traditional Irish music with useful metadata such as tune name, key signature, time signature, composer and discography. MATT2 works by using a number of algorithms to automatically transcribe digital audio to be annotated to the ABC music notation language. It then compares these transcriptions against a corpus of 860 human made transcriptions in ABC using a variation of the edit distance algorithm. Results using MATT2 to annotate fifty recordings of flute and fiddle tunes demonstrate a high success rate …

The Annotation Of Traditional Irish Dance Music Using Matt2 And Tansey, Bryan Duggan, Brendan O'Shea, Mikel Gainza

Conference papers

Currents estimates put the canon of traditional Irish dance tunes at least 7,000 compositions. Given this diversity, a common problem faced by musicians and ethnomusicologists is identifying tunes from recordings. This is evident even in the number of commercial recordings whose title is gan ainm (without name). This work attempts to solve this problem by developing a Content Based Music Information Retrieval (CBMIR) System adapted to the characteristics of traditional Irish music. A system is presented called MATT2 (Machine Annotation of Traditional Tunes) whose primary goal is to annotate recordings of traditional Irish dance music with useful meta-data including tune …

Sweetening The Dataset : Using Active Learning To Label Unlabelled Datasets, Rong Hu, Brian Mac Namee, Sarah Jane Delany

Conference papers

Supervised machine learning approaches assume the existence of a large collection of manually labelled examples of the problem under consideration. However, in many cases such a collection does not exist and creating one is time consuming and expensive. This can be a barrier to the use of supervised learning in certain situations, particularly when the doubt as to whether the system will work or not makes the cost of creating a dataset unjustifable. Active learning is a machine learning technique that has been used widely to create classification systems in the absence of large numbers of labelled examples, but that …

Autopilot: Simulating Changing Concepts In Real Data, Patrick Lindstrom, Sarah Jane Delany, Brian Mac Namee

Conference papers

An increasingly important area in supervised incremental learning is learning in the presence of changing concepts. Research into concept drift is hampered by the lack of availability of controllable `real life' datasets. In this paper we propose an approach for generating real life data over which we have control of the concept and can generate data exhibiting different types of concept drift. The approach uses a 3-D driving game to produce a data stream of instances describing how to drive around a track. The classification problem is learning the driving technique of the driver, which can be affected by changes …

Medical Language Processing For Patient Diagnosis Using Text Classification And Negation Labelling, Brian Mac Namee, John D. Kelleher, Sarah Jane Delany

Conference papers

This paper describes the approach of the DIT AIGroup to the i2b2 Obesity Challenge to build a system to diagnose obesity and related co-morbidities from narrative, unstructured patient records. Based on experimental results a system was developed which used knowledge-light text classification using decision trees, and negation labelling.

A Review Of Assistive Technology And Writing Skills For Students With Physical And Educational Disabilities, Howard P. Parette, Jack J. Hourcade, George R. Peterson-Karlan

Faculty Publications - College of Education

In recent years effective instruction in reading for learners with physical
and educational disabilities has received great attention in the schools.
However, instruction in the corollary skill of writing has received considerably less emphasis. This review paper notes that through the use of assistive technology, students with a variety of physical and educational
disabilities can learn to effectively (a) plan and organize their writing,
(b) draft and transcribe their work, and (c) edit and revise their narrative
and expository writing.
With teachers increasingly being held accountable for the development of
literacy skills in all students, including those students with physical …

Smoking Cessation: Why Do Smokers Fail?, Joyce M. Wolburg

College of Communication Faculty Research and Publications

Purpose:

The purpose of this article is to probe three explanations for the difficulty that cigarette smokers have in quitting: the addictive nature of the product; the failure to deliver messages with effective quit strategies; and the resistance to enacting smoking bans in bars and restaurants. It aims to argue that the latter two issues result in misplaced marketing.

Design/methodology/approach:

This article examines data from published research, interviews with smokers who have successfully quit, and government statistics to have a clearer picture of the issues.

Findings:

Smokers are exposed to anti‐smoking messages created to discourage youth from starting to smoke, …
