Curate And Storyspace: An Ontology And Web-Based Environment For Describing Curatorial Narratives, Paul Mulholland, Annika Wolff, Trevolr Collins Jan 2012

Curate And Storyspace: An Ontology And Web-Based Environment For Describing Curatorial Narratives, Paul Mulholland, Annika Wolff, Trevolr Collins

Publications

focus on describing the heritage objects that the museum holds in its collection. These are used to manage and describe individual heritage objects according to properties such as artist, date and preservation requirements. Curatorial narratives, such as physical or online exhibitions tell a story that spans across heritage objects and have a meaning that does not necessarily reside in the individual heritage objects themselves. Here we present curate, an ontology for describing curatorial narratives. This draws on structuralist accounts that distinguish the narrative from the story and plot, and also a detailed analysis of two museum exhibitions and the curatorial …

Storyspace: A Story-Driven Approach For Creating Musuem Narratives, Annika Wolff, Paul Mulholland, Tevor Collins Jan 2012

Storyspace: A Story-Driven Approach For Creating Musuem Narratives, Annika Wolff, Paul Mulholland, Tevor Collins

Publications

In a curated exhibition of a museum or art gallery, a selection of heritage objects and associated information is presented to a visitor for the purpose of telling a story about them. The same underlying story can be presented in a number of different ways. This paper describes techniques for creating multiple alternative narrative structures from a single underlying story, by selecting different organising principles for the events and plot structures of the story. These authorial decisions can produce different dramatic effects. Storyspace is a web interface to an ontology for describing curatorial narratives. We describe how the narrative component …

Chemical And Electrical Approaches To Sedation Of Cobia: Induction, Recovery, And Physiological Responses, Jesse Trushenski, John C. Bowzer, James D. Bowker, Michael H. Schwarz

Publications

To support the growing interest in marine fisheries research in areas such as biotelemetry, tagging, and tracking, we assessed the ability of various sedatives to facilitate this research in juvenile cobias Rachycentron canadum (∼300 g), namely, tricaine methanesulfonate (MS-222; 150 mg/L), carbon dioxide (CO2; ∼750 mg/L), eugenol (60 mg/L), benzocaine (150 mg/L), and pulsed-DC electrosedation (100 V, 30 Hz, 25% duty cycle, 5-s exposure). Induction times (CO2 [z] > benzocaine [y] > eugenol [y] > MS-222 [y] > electrosedation [x]), recovery of equilibrium (CO2 [z] > eugenol [z] > MS-222 [y] > benzocaine [y] > electrosedation [x]), and responsiveness to tactile stimulus (eugenol [z] …

Power Method Distributions Through Conventional Moments And L-Moments, Flaviu A. Hodis, Todd C. Headrick, Yanyan Sheng Jan 2012

Power Method Distributions Through Conventional Moments And L-Moments, Flaviu A. Hodis, Todd C. Headrick, Yanyan Sheng

Publications

This paper develops two families of power method (PM) distributions based on polynomial transformations of the (1) Uniform, (2) Triangular, (3) Normal, (4) D-Logistic, and (5) Logistic distributions. One family is developed in the context of conventional method of moments and the other family is derived through the method of L-moments. As such, each of the five conventional moment-based PM classes has an analogous L-moment based class. A primary focus of the development is on PM polynomial transformations of order three. Specifically, systems of equations are derived for computing polynomial coefficients for user specified values of skew ( …

Characterizing Tukey H And Hh-Distributions Through L-Moments And The L-Correlation, Todd C. Headrick, Mohan D. Pant Jan 2012

Characterizing Tukey H And Hh-Distributions Through L-Moments And The L-Correlation, Todd C. Headrick, Mohan D. Pant

Publications

This paper introduces the Tukey family of symmetric h and asymmetric hh-distributions in the contexts of univariate L-moments and the L-correlation. Included is the development of a procedure for specifying nonnormal distributions with controlled degrees of L-skew, L-kurtosis, and L-correlations. The procedure can be applied in a variety of settings such as modeling events (e.g., risk analysis, extreme events) and Monte Carlo or simulation studies. Further, it is demonstrated that estimates of L-skew, L-kurtosis, and L-correlation are substantially superior to conventional product-moment estimates of skew, kurtosis, and Pearson correlation in terms …

A Doubling Technique For The Power Method Transformations, Mohan D. Pant, Todd C. Headrick Jan 2012

A Doubling Technique For The Power Method Transformations, Mohan D. Pant, Todd C. Headrick

Publications

Power method polynomials are used for simulating non-normal distributions with specified product moments or L-moments. The power method is capable of producing distributions with extreme values of skew (L-skew) and kurtosis (L-kurtosis). However, these distributions can be extremely peaked and thus not representative of real-world data. To obviate this problem, two families of distributions are introduced based on a doubling technique with symmetric standard normal and logistic power method distributions. The primary focus of the methodology is in the context of L-moment theory. As such, L-moment based systems of equations are derived for …

An L-Moment-Based Analog For The Schmeiser-Deutsch Class Of Distributions, Todd C. Headrick, Mohan D. Pant Jan 2012

An L-Moment-Based Analog For The Schmeiser-Deutsch Class Of Distributions, Todd C. Headrick, Mohan D. Pant

Publications

This paper characterizes the conventional moment-based Schmeiser-Deutsch (S-D) class of distributions through the method of L-moments. The system can be used in a variety of settings such as simulation or modeling various processes. A procedure is also described for simulating S-D distributions with specified L-moments and L-correlations. The Monte Carlo results presented in this study indicate that the estimates of L-skew, L-kurtosis, and L-correlation associated with the S-D class of distributions are substantially superior to their corresponding conventional product-moment estimators in terms of relative bias—most notably when sample sizes are small.

A Logistic L-Moment-Based Analog For The Tukey G-H, G, H, And H-H System Of Distributions, Todd C. Headrick, Mohan D. Pant Jan 2012

A Logistic L-Moment-Based Analog For The Tukey G-H, G, H, And H-H System Of Distributions, Todd C. Headrick, Mohan D. Pant

Publications

This paper introduces a standard logistic L-moment-based system of distributions. The proposed system is an analog to the standard normal conventional moment-based Tukey g-h, g, h, and h-h system of distributions. The system also consists of four classes of distributions and is referred to as (i) asymmetric γ-κ, (ii) log-logistic γ, (iii) symmetric κ, and (iv) asymmetric κL-κR. The system can be used in a variety of settings such as simulation or modeling events—most notably when heavytailed distributions are of interest. A procedure is also described for simulating γ-κ, γ, κ, and κL …

High Performance Gibbs Sampling For Irtmodels Using Row-Wise Decomposition, Yanyan Sheng, Mona Rahimi Jan 2012

High Performance Gibbs Sampling For Irtmodels Using Row-Wise Decomposition, Yanyan Sheng, Mona Rahimi

Publications

Item response theory (IRT) is a popular approach used for addressing statistical problems in psychometrics as well as in other fields. The fully Bayesian approach for estimating IRT models is computationally expensive. This limits the use of the procedure in real applications. In an effort to reduce the execution time, a previous study shows that high performance computing provides a solution by achieving a considerable speedup via the use of multiple processors. Given the high data dependencies in a single Markov chain for IRT models, it is not possible to avoid communication overhead among processors. This study is to reduce …

Ring Maps For Spatial Visualization Of Multivariate Epidemiological Data, Sarah E. Battersby, John E. Stewart, Ana Lopez-De Fede, Kevin C. Remington Jan 2012

Ring Maps For Spatial Visualization Of Multivariate Epidemiological Data, Sarah E. Battersby, John E. Stewart, Ana Lopez-De Fede, Kevin C. Remington

Publications

Epidemiological research often involves the visual exploration of numerous attributes to help discern patterns between health and characteristics of the physical, socioeconomic, or built environment. Unfortunately, many of the multivariate mapping techniques discussed throughout the cartographic literature can be challenging to create or interpret—particularly for individuals without a cartographic background. In this paper, we present a new style of multivariate map—the ring map—to aid in basic visualization of multivariate datasets. For purposes of example, we focus on the use of the ring map style for exploring county-level epidemiological data for the state of South Carolina to examine patterns of age, …

Vortex Patterns Beyond Hypergeometric, Andrei Ludu Jan 2012

Vortex Patterns Beyond Hypergeometric, Andrei Ludu

Publications

We prove that loop vortices are created by a point-like magnetic dipole in an infinite superconductor space. The geometry of the vortex system is obtained through analytic solutions of the linearized Ginzburg-Landau equation described in terms of Heun functions, generalizing the traditional hypergeometric behavior of such magnetic singularity.

Small-Scale Aid Donors, Agribusiness, And The Zambian Export Sector, John R. Ledgerwood, Stephen N. Morgan Jan 2012

Small-Scale Aid Donors, Agribusiness, And The Zambian Export Sector, John R. Ledgerwood, Stephen N. Morgan

Publications

Production of high value agriculture and natural products has become a key instrument in economic development programs to accomplish the dual objectives of raising rural incomes and conserving valuable environmental resources. Rapid growth in global demand for organic and natural products has provided a strong economic incentive for small scale aid agencies to expand into this niche market. Through this analysis we investigate the economic impact that aid funded agricultural production has had on rural residents of Zambia and how this development strategy allows small scale aid donors to capitalize on the business and export opportunities in the Central African …

Disparities In Weather Education Across Professional Flight Baccalaureate Degree Programs, Thomas A. Guinn, Krista M. Rader, Thomas A. Guinn

Publications

The required meteorology coursework for 22 accredited professional flight baccalaureate degree programs was examined and compared. Significant differences were noted in both the number of required meteorology courses as well as the number of required meteorology credit hours. While all programs required at least one three-credit meteorology course, not all programs required an aviation-specific meteorology course. In addition to the required number of meteorology courses and credit hours, topics within the aviation-specific meteorology courses were also examined. The study showed the topics of “flight hazards” and “aviation weather reports and charts” were identified most frequently in course descriptions, followed third …

The Importance Of The Political In Immigration Federalism, Pratheepan Gulasekaram, S. Karthick Ramakrishnan Jan 2012

The Importance Of The Political In Immigration Federalism, Pratheepan Gulasekaram, S. Karthick Ramakrishnan

Publications

This Article provides a systematic, empirical investigation of the genesis of state and local immigration regulations, discrediting the popular notion that they are caused by uneven demographic pressures across the country. It also proffers a novel theory to explain the proliferation of these policies and queries the implications of this new model for federalism analysis. The story we tell in this paper is both political and legal; understanding immigration politics uncovers vital truths about the recent rise of subnational involvement in a policy arena that courts and commentators have traditionally ascribed to the federal government. Thus, this article connects the …

"Other Spaces" In Legal Pedagogy, Lolita Buckner Inniss Jan 2012

"Other Spaces" In Legal Pedagogy, Lolita Buckner Inniss

Publications

There is an increasing focus upon the material and metaphoric spatial dimensions of various academic disciplines, including law. This essay considers the spatial dimensions of legal pedagogy, focusing on Critical Race Theory (CRT). The essay first explains the "critical program" in law and how CRT grows out of it. The essay then suggests that the critical program, and especially CRT, is as much a human geographic or spatial construct as it is a social, political or historic one, and briefly describes the nature of human geography and legal geography. It next considers how metaphors for understanding CRT's position in legal …

The Market As A Legal Concept, Justin Deystone Jan 2012

The Market As A Legal Concept, Justin Deystone

Publications

In the wake of the recent financial crisis of 2008, and in the run-up to what some are calling a perfect fiscal storm, there is no shortage of commentary on the need for fundamental market reform. Though there are certainly disagreements about where the real problems are and what to do, almost all the commentary remains wedded to an old and entirely false image of “free competition.” Of course, there is hardly consensus about whether markets require the heavy hand of regulative control, or are better left to regulate themselves, but a belief in the distinction between these two images …

Where You Stand Depends On Where You Sit: Bureaucratic Politics In Federal Workplace Agencies Serving Undocumented Workers, Ming H. Chen Jan 2012

Where You Stand Depends On Where You Sit: Bureaucratic Politics In Federal Workplace Agencies Serving Undocumented Workers, Ming H. Chen

Publications

This Article integrates social science theory about immigrant incorporation and administrative agencies with empirical data about immigrant-serving federal workplace agencies to illuminate the role of bureaucracies in the construction of rights. More specifically, it contends that immigrants' rights can be protected when workplace agencies incorporate immigrants into labor law enforcement in accordance with the agencies' professional ethos and organizational mandates. Building on Miles' Law that "where you stand depends on where you sit," this Article argues that agencies exercise discretion in the face of contested law and in contravention to a political climate hostile to undocumented immigrants for the purpose …

Race As A Legal Concept, Justin Deystone Jan 2012

Race As A Legal Concept, Justin Deystone

Publications

Race is a legal concept, and like all legal concepts, it is a matrix of rules. Although the legal conception of race has shifted over time, up from slavery and to the present, one element in the matrix has remained the same: the background rules of race have always taken a view of racial identity as a natural aspect of human biology. To be sure, characterizations of the rule have oftentimes kept pace with developments in race science, and the original invention of race as a rationale for the subordination of certain human populations is now a rationale with little …

The Role Of Equipoise In Family Law, Deborah Cantrell Jan 2012

The Role Of Equipoise In Family Law, Deborah Cantrell

Publications

Scholars reviewing family law over the last twenty years have described the field as having undergone a revolution. While true, both scholars and front-line family law advocates have failed to invent a satisfying end to the revolution. This Article takes up that challenge and offers a novel way forward, It identifies two translation challenges that have prevented the revolution from reaching its end. The first challenge is translating reform so that its benefits accrue equally across all kinds of participants--rich and poor, those with lawyers and those without. The second challenge is translating theory into on-the-ground practices useful to family …
