Manual Evaluation Of Synthesised Sign Language Avatars, Robert G. Smith Mr, Brian Nolan Dr. Jan 2013

Manual Evaluation Of Synthesised Sign Language Avatars, Robert G. Smith Mr, Brian Nolan Dr.

Conference Papers

The evaluation discussed in this paper explores the role that underlying facial expressions might have regarding understandability in sign language avatars. Focusing specifically on Irish Sign Language (ISL), we examine the Deaf community’s appetite for sign language avatars. The work presented explores the following hypothesis: Augmenting an existing avatar with various combinations of the 7 widely accepted universal emotions identified by Ekman [1] to achieve underlying facial expressions, will make that avatar more human-like and consequently improve usability and understandability for the ISL user. Using human evaluation methods [2] we compare an augmented set of avatar utterances against a baseline …

The Wonder-Clause, Anna Gelpern, Mitu Gulati Jan 2013

The Wonder-Clause, Anna Gelpern, Mitu Gulati

Faculty Scholarship

The Greek debt crisis prompted EU officials to embark on a radical reconstruction of the European sovereign debt markets. Prominently featured in this reconstruction was a set of contract provisions called Collective Action Clauses, or CACs. CACs are supposed to help governments and private creditors to renegotiate unsustainable debt contracts, and obviate the need for EU bailouts. But European sovereign debt contacts were already amenable to restructuring; adding CACs could make it harder. Why, then, promote CACs at all, and cast them in such a central role in the market reform initiative? Using interviews with participants in the initiative and …

Cheap, Easy, Or Connected: The Conditions For Creating Group Coordination, Mathew D. Mccubbins, Daniel Rodriguez, Nicholas Weller Jan 2013

Cheap, Easy, Or Connected: The Conditions For Creating Group Coordination, Mathew D. Mccubbins, Daniel Rodriguez, Nicholas Weller

Faculty Scholarship

In both legal and political settings there has been a push toward adopting institutions that encourage consensus. The key feature of these institutions is that they bring interested parties together to communicate with each other. Existing research about the success or failure of particular institutions is ambiguous. Therefore, we turn our attention to understanding the general conditions when consensus is achievable, and we test experimentally three crucial factors that affect a group's ability to achieve consensus: (1) the difficulty of the problem, (2) the costs of communication, and (3) the structure of communication. Using multiple experimental approaches, we find that …

Pricing Compliance: When Formal Remedies Displace Reputational Sanctions, Rachel Brewster Jan 2013

Pricing Compliance: When Formal Remedies Displace Reputational Sanctions, Rachel Brewster

Faculty Scholarship

The conventional wisdom in international law is that dispute resolution institutions sharpen the reputational costs to states. This article challenges this understanding by examining how the inclusion of dispute resolution tribunals and remedy regimes can alter reputational analysis by shifting the audience¹s understanding of how mandatory a treaty's substantive obligations are. Drawing on the distinction between prices and sanctions, this article contests the assumption that the introduction of a remedy regime in international agreements will regularly increase compliance with the treaty¹s substantive terms. Instead, some remedy regimes may 'price' deviations from the treaty¹s terms and thereby facilitate breaches of the …

Is There A Best Cow Size For Beef Cattle Producers?, Matthew Stockton, Sunil P. Dhoubhadel, Leslie Aaron Stalker Jan 2013

Is There A Best Cow Size For Beef Cattle Producers?, Matthew Stockton, Sunil P. Dhoubhadel, Leslie Aaron Stalker

Cornhusker Economics

There are individuals in the beef cattle industry who claim there is a need for smaller brood cows, because smaller cows are more efficient and therefore more profitable. On the other hand, there are those who claim the larger the cow the better, and these generally are those who feed calves to slaughter. The proponents of both sides seem to have logical reasons that support their claims. So who is right?

Plea Bargaining, Sentence Modifications, And The Real World, Julian A. Cook Jan 2013

Plea Bargaining, Sentence Modifications, And The Real World, Julian A. Cook

Scholarly Works

This article examines the 2011 Supreme Court decision in United States v. Freeman. At issue was whether defendants, such as Freeman, who enter a guilty plea pursuant to a binding plea agreement, are entitled to seek a modification of their sentence when the guideline range applicable to their offense has subsequently been lowered by the United States Sentencing Commission. By a five-to-four vote, the Court found that Freeman was eligible to seek a sentence reduction. However, as the article explains, the concurring and controlling opinion of Justice Sotomayor may ultimately prove to be problematic for criminal defendants generally and for …

A Heroic Journey Within Videogames And The Effects Of Player Experience, Jeremiah Moffitt Jan 2013

A Heroic Journey Within Videogames And The Effects Of Player Experience, Jeremiah Moffitt

Honors Program Theses

The popularity of videogames globally is increasing dramatically. The gamer explores first hand fantastic worlds. The story structure of many games follows the hero's journey-a rite of passage that social scientists view as a transformative experience. Although the content of the journey may be culturally specific, the similar structural components of the journey enable the hero to ultimately complete his/her journey as a changed person. I hypothesize that during the playing process, the gamer incorporates the experiences of his/her character and shares in some of these transformative processes. My research is based on participant observation and open-ended interviews with individuals …

Categorical Vs. Dimensional Models Of Mental Health Assessment, Nic Stewart Jan 2013

Categorical Vs. Dimensional Models Of Mental Health Assessment, Nic Stewart

Honors Program Theses

The model that is currently in place is the categorical model and its use has been widespread since 1980 when the DSM-III was published and used internationally for categorical assessment (Mayes & Horwitz, 2005). It has since been widely utilized by professionals, but is not without flaws. Based on the argument for an alternative approach, researchers have argued several limitations of the categorical model: that no true discrete mental illness can be reasonably operationalized by categorical measures; that negative stigmas can accompany a diagnosis of mental illness; that there is inherent uncertainty when making diagnoses, whether to perceive certain information …

The Role Of Imagery In The Priming Of A Mental Construct, Patrick Michael Tiernan Jan 2013

The Role Of Imagery In The Priming Of A Mental Construct, Patrick Michael Tiernan

Honors Program Theses

Priming is a term in psychology that refers to the unconscious activation of internal mental knowledge structures, such as trait concepts and stereotypes or mental representations of a stored idea, by specific details in the surrounding external environment (Bargh, Chen, & Burrows, 1996). This thesis conceptually replicated a priming experiment that used "old age" themed words in a sentence task to slow the walking speed of participants leaving the experimental room (Bargh, Chen, & Burrows, 1996). In the replication attempt University of Northern Iowa alumni themed posters were placed along a walking path near Rod Library on the UNI campus. …

It's A Juggling Act: An Examination Of Work-School Conflict, Danielle Barbara Stuck Jan 2013

It's A Juggling Act: An Examination Of Work-School Conflict, Danielle Barbara Stuck

Honors Program Theses

Working while enrolled in college has become increasingly prominent, yet its effects on school outcomes and student well-being are not yet understood. The purpose of this study was to examine the effects of individual differences and nuances in the school and work domains to obtain a more precise model of Work-School Conflict [WSC]. Data were collected from 401 undergraduate and graduate students from the University of Northern Iowa and analyzed using hierarchical (blocked) linear regression analyses. While job flexibility negatively predicted WSC, job permeability interacted with number of hours worked off-campus and workload, differentially predicting WSC; while permeability decreased WSC …

Defensive Communication Between Professors And Students And Its Effects On Student Outcomes, Alexa Pomerenk Jan 2013

Defensive Communication Between Professors And Students And Its Effects On Student Outcomes, Alexa Pomerenk

Honors Program Theses

This study investigated the relationship between defensive communication and student outcomes in college classrooms. The researcher hypothesized that students would perceive a greater defensive climate in classes taught by their least favorite professors, and that the defensive climate would encourage the use of coping mechanisms. Defensive communication was also hypothesized to negatively affect student grades, attendance, and course satisfaction and to increase student burnout. Surveys were administered to college students, and results supported all hypotheses. Findings showed that students linked defensive attributes to their least favorite professors more frequently than they did to their favorite professors, and they reported using …

Going Offline: Personality And Its Effects On The Transition Of Online Relationships To The Offline World, Morgan Johnson Jan 2013

Going Offline: Personality And Its Effects On The Transition Of Online Relationships To The Offline World, Morgan Johnson

Honors Program Theses

Because the internet is a relatively new technology, few studies have researched the correlations between online behavior and personality. As such, this study set out to determine if online friendships and personality are related. In this study differences in personality were examined between individuals who have met their online friends face-to-face and those who have not. A survey was distributed online using the Five Factor Model to measure personality. Participants in this study were recruited from an online community called Nerdfighteria. The results found that the facets of the Five Factor Model of personality were largely found not to be …

Uni's Dance Craze: A Psychological Analysis And Creative Documentary On 'The Interlude Dance' And 'The Dance Party', Ian Goldsmith Jan 2013

Uni's Dance Craze: A Psychological Analysis And Creative Documentary On 'The Interlude Dance' And 'The Dance Party', Ian Goldsmith

Honors Program Theses

The UNI campus has been part of an epidemic: a dance epidemic. “The Interlude Dance” and “The Dance Party” are two recent dance phenomena that have played a major role in my undergraduate experience. I sought to study these phenomena through an analytical approach. I sought to determine the psychosocial factors that lead to the initial and continuing success of “The Interlude Dance” and “The Dance Party”, and to build conceptual connections between both phenomena. This creative-research hybrid project culminated in a documentary short-film.

The Sustainable And Entrepreneurial Park? Contradictions And Persistent Antagonisms At Sydney's Olympic Park, Mark Davidson Jan 2013

The Sustainable And Entrepreneurial Park? Contradictions And Persistent Antagonisms At Sydney's Olympic Park, Mark Davidson

Geography

Urban parks have long been used by policy makers to achieve specific policy goals. In recent years, two sets of policy goals have become commonly associated with park planning. The first set of goals can be characterized as being neoliberal, where parks have been built and reformed to generate certain economic and governmental outcomes. The second set of policy goals is associated with sustainability, where parks have been utilized as tools in such things as the mitigation of climate change and community building. The aim of this paper is to examine how these two sets of policy goals have come …

We Have Never Been "Post-Political", James Mccarthy Jan 2013

We Have Never Been "Post-Political", James Mccarthy

Geography

The Progressive Era attempt to 'depoliticize' environmental governance was of course an utter failure for a host of reasons: powerful economic and political interests found or made entry points into supposedly sealed-off arenas, eventually culminating in the phenomenon of agency capture. Scientists and technocrats carried their own politics into their work, consciously or unconsciously; the people affected by new property relations and management regimes resisted and reconfigured the newly emergent socionatures in their areas in a variety of ways, producing a reality more complicated than, and often at odds with, the superficially clear official policy; and so on. It is …

Leisure Trends And Technology Within Generations X, Y, And Z, Alyssa Eisenman Jan 2013

Leisure Trends And Technology Within Generations X, Y, And Z, Alyssa Eisenman

Honors Program Theses

A generation is defined as "a grouping of individuals who share birth years and thus share life stages" (Hunter-Jones, 2012, p. 2). This research paper will focus on Generations X, Y, and Z, inclusive of their general characteristics and the various ways in which each generation chooses to recreate and spend their leisure time. Generations X, Y, and Z make up a majority of today's population from our education system as students to the workplace as employees. They make up the current college student body, as some members of Generation X are in graduate school, and members of Generations Y …

Global Land Governance: From Territory To Flow?, Thomas Sikor, Graeme Auld, Anthony J. Bebbington, Tor A. Benjaminsen, Bradford S. Gentry, Carol Hunsberger, Anne Marie Izac, Matias E. Margulis, Tobias Plieninger, Heike Schroeder, Caroline Upton

Geography

This article reviews recent research on contemporary transformations of global land governance. It shows how changes in global governance have facilitated and responded to radical revalorizations of land, together driving the intensified competition and struggles over land observed in many other contributions to this special issue. The rules in place to govern land use are shifting from 'territorial' toward 'flow-centered' arrangements, the latter referring to governance that targets particular flows of resources or goods, such as certification of agricultural or wood products. The intensifying competition over land coupled with shifts toward flow-centered governance has generated land uses involving new forms …

Bebbington, Karl Hennermann, Julia Mcmorrow, David A. Springate, Bolier Torres, Nathan K. Truelove, Niklas Tysklind, Santiago Villamarín, Richard F. Preziosi

Geography

We compare conservation outcomes between a protected area (PA) and four indigenous common-property regimes (CPRs) under differing degrees of market integration in the Ecuadorian Amazon. We first assess how market forces and common-pool resource institutions governing processes of forest conversion affect biodiversity and forest cover, and whether institutions mitigate the effect of market forces. We then analyze how biodiversity and forest cover differ between a PA, and communities with different market access. Finally, we link biodiversity and forest cover changes within communities to differences in land-use practices. While we show similar levels of forest cover and biodiversity between the PA …

Williams, J. Ardö, M. Boucher, B. Cappelaere, A. De Grandcourt, A. Nickless, Y. Nouvellon, R. Scholes, W. Kutsch

Geography

Climate change is expected to have the greatest impact on the world's economically poor. In the Sahel, a climatically sensitive region where rain-fed agriculture is the primary livelihood, expected decreases in water supply will increase food insecurity. Studies on climate change and the intensification of the water cycle in sub-Saharan Africa are few. This is due in part to poor calibration of modeled evapotranspiration (ET), a key input in continental-scale hydrologic models. In this study, a remote sensing model of transpiration (the primary component of ET), driven by a time series of vegetation indices, was used to substitute transpiration from …

Satellite-Based Estimates Of Antarctic Surface Meltwater Fluxes, Luke D. Trusel, Karen E. Frey, Sarah B. Das, Peter Kuipers Munneke, Michiel R. Van Den Broeke Jan 2013

Satellite-Based Estimates Of Antarctic Surface Meltwater Fluxes, Luke D. Trusel, Karen E. Frey, Sarah B. Das, Peter Kuipers Munneke, Michiel R. Van Den Broeke

Geography

This study generates novel satellite-derived estimates of Antarctic-wide annual (1999-2009) surface meltwater production using an empirical relationship between radar backscatter from the QuikSCAT (QSCAT) satellite and melt calculated from in situ energy balance observations. The resulting QSCAT-derived melt fluxes significantly agree with output from the regional climate model RACMO2.1 and with independent ground-based observations. The high-resolution (4.45 km) QSCAT-based melt fluxes uniquely detect interannually persistent and intense melt (>400 mm water equivalent (w.e.) year-1) on interior Larsen C Ice Shelf that is not simulated by RACMO2.1. This supports a growing understanding of the importance of a föhn effect in …

Ice Sheet Record Of Recent Sea-Ice Behavior And Polynya Variability In The Amundsen Sea, West Antarctica, Alison S. Criscitiello, Sarah B. Das, Matthew J. Evans, Karen E. Frey, Howard Conway, Ian Joughin, Brooke Medley, Eric J. Steig Jan 2013

Ice Sheet Record Of Recent Sea-Ice Behavior And Polynya Variability In The Amundsen Sea, West Antarctica, Alison S. Criscitiello, Sarah B. Das, Matthew J. Evans, Karen E. Frey, Howard Conway, Ian Joughin, Brooke Medley, Eric J. Steig

Geography

[1] Our understanding of past sea-ice variability is limited by the short length of satellite and instrumental records. Proxy records can extend these observations but require further development and validation. We compare methanesulfonic acid (MSA) and chloride (Cl-) concentrations from a new firn core from coastal West Antarctica with satellite-derived observations of regional sea-ice concentration (SIC) in the Amundsen Sea (AS) to evaluate spatial and temporal correlations from 2002-2010. The high accumulation rate (∼39 g·cm-2·yr-1) provides monthly resolved records of MSA and Cl-, allowing detailed investigation of how regional SIC is recorded in the ice-sheet stratigraphy. Over the period 2002-2010 …

Casualties Of The Drug War, Allan Wachendorfer Jan 2013

Casualties Of The Drug War, Allan Wachendorfer

Senior Honors Theses and Projects

The "War on Drugs" started with the Controlled Substances Act and expanded with the Sentencing Reform Act and Anti-Drug Abuse Acts. Mostly they have provided tertiary measures that have done little to eradicate drugs or drug addiction. Instead, the U.S. remains the number one nation in the world in drug use. In addition, there is an ever growing prison population that has surpassed unsustainable levels. Many of the people behind bars are there for drug related crimes. It is time to examine drug policies, particularly those that send people to prison, and to consider establishing more programs that help people …

The Effects Of Extending Trust And Distrust To The Outgroup In Northern Ireland: Intergroup Emotions And Anticipated Intergroup Relations, Jared B. Kenworthy, Elissa Myers, Lauren E. Coursey, Jason R. Popan, Miles Hewstone Jan 2013

The Effects Of Extending Trust And Distrust To The Outgroup In Northern Ireland: Intergroup Emotions And Anticipated Intergroup Relations, Jared B. Kenworthy, Elissa Myers, Lauren E. Coursey, Jason R. Popan, Miles Hewstone

Psychological Science Faculty Publications

Two studies examined perceptions of risk, threat, and emotions experienced once a community leader has made the decision to extend trust or distrust to the outgroup, in the context of Northern Ireland. Study 1 examined the impact of three factors — the extension of trust or distrust, a social climate of threat or reduced threat, and high/low group identification — on perceived risk and group-level emotion. Study 2 examined the impact of these factors on expected negative intergroup relations and symbolic and realistic outcomes. Results from both studies demonstrated that: (1) evaluation of a community leader’s extension of trust or …

Global Trends In Seasonality Of Normalized Difference Vegetation Index (Ndvi), 1982-2011, J. Ronald Eastman, Florencia Sangermano, Elia A. Machado, John Rogan, Assaf Anyamba

Geography

A 30-year series of global monthly Normalized Difference Vegetation Index (NDVI) imagery derived from the Global Inventory Modeling and Mapping Studies (GIMMS) NDVI3g archive was analyzed for the presence of trends in changing seasonality. Using the Seasonal Trend Analysis (STA) procedure, over half (56.30%) of land surfaces were found to exhibit significant trends. Almost half (46.10%) of the significant trends belonged to three classes of seasonal trends (or changes). Class 1 consisted of areas that experienced a uniform increase in NDVI throughout the year, and was primarily associated with forested areas, particularly broadleaf forests. Class 2 consisted of areas experiencing …
