The purpose of the present study was to assess the preparedness of the veterinary profession to communicate with limited English proficient Spanish-speaking pet owners (LEP SSPOs). Results of surveys with 393 Latino pet owners, 383 small animal veterinarians and staff, and over 2000 veterinary students indicate that interaction between veterinary professionals and LEP SSPOs is not a rare occurrence: Veterinarians in states with large established or fast-growing Latino communities are seeing LEP SSPOs and their pets on a regular basis: 89% of veterinarians have LEP Spanish-speaking clients, over half of these practitioners are seeing LEP SSPOs weekly, and over half …


Manifold Learning Based Spectral Unmixing Of Hyperspectral Remote Sensing Data, Jun-Hwa Chi Oct 2013

Manifold Learning Based Spectral Unmixing Of Hyperspectral Remote Sensing Data, Jun-Hwa Chi

Open Access Dissertations

Nonlinear mixing effects inherent in hyperspectral data are not properly represented in linear spectral unmixing models. Although direct nonlinear unmixing models provide capability to capture nonlinear phenomena, they are difficult to formulate and the results are not always generalizable. Manifold learning based spectral unmixing accommodates nonlinearity in the data in the feature extraction stage followed by linear mixing, thereby incorporating some characteristics of nonlinearity while retaining advantages of linear unmixing approaches. Since endmember selection is critical to successful spectral unmixing, it is important to select proper endmembers from the manifold space. However, excessive computational burden hinders development of manifolds for …


Adaptive Targeting: Engaging Farmers To Assess Perceptions And Improve Watershed Modeling, Optimization, And Adoption Of Agricultural Conservation Practices, Margaret Mccahon Kalcic Oct 2013

Adaptive Targeting: Engaging Farmers To Assess Perceptions And Improve Watershed Modeling, Optimization, And Adoption Of Agricultural Conservation Practices, Margaret Mccahon Kalcic

Open Access Dissertations

Targeting agricultural conservation practices to farmland that has the greatest impact on surface water quality has received wide support from scientists and watershed managers. The targeting approach has, however, been politically contentious as many believe farmers will oppose the approach on grounds such as privacy invasion and unfair distribution of government incentives. Targeting conservation practices using complex optimization models has become common in the scientific community, and yet targeted results are underutilized in practice because of difficulties such as knowledge transfer and absence of a political framework for their use. For targeting to be successful, it must be politically supported …

An Eriksonian Approach To Consumer Identity, Sandra Rathod

Open Access Dissertations

Rathod, Sandra R. Ph.D., Purdue University, December 2013. An Eriksonian Approach to Consumer Identity. Major Professor: Richard A. Feinberg.

Ego development is the fifth stage in Erikson's Lifecycle Development theory (1959) and is a major psychosocial stage beginning in adolescence and lasting into emerging adulthood. Past research based upon Marcia's Ego Identity Status Paradigm (1996) has investigated a number of ideological and interpersonal domains relevant to one's ego identity, however in today's consumer societies, where what you have is at least as important is who you are or what you do, an Eriksonian approach to consumer ego identity (CEI) has …

Impacts And Feasibility Of The Us And The Eu Sustainability Criteria On Existing Land-Use Practices, Krissana Treesilvattanakul

Open Access Dissertations

Several studies have examined the land use and economic consequences of national and multi-national biofuel policies. They explored the impacts of biofuels mandates mainly based on the quantitative biofuel targets. However, the recently updated renewable policies of the United States and the European Union, which are the US Renewable Fuel Standard (RFS) and EU Directive 2009/28 of the Renewable Energy Directive (RED) both place restrictions on land that can be used to produce biofuel, and these restrictions are generally known as sustainability criteria. This research aims to determine to what extent sustainability criteria are actually binding; that is, would they …

Understanding Teacher/Coach Role Stressors And Burnout, Kevin Andrew Richards Oct 2013

Understanding Teacher/Coach Role Stressors And Burnout, Kevin Andrew Richards

Open Access Dissertations

Teaching has long been considered a stressful profession and is becoming even more stressful because of recent changes in state- and national-level educational policies that govern K-12 education. Teachers who take on additional, extracurricular roles, such as athletic coaching, may be even more prone to stress and burnout. Using occupational socialization theory and role theory, the purpose of this dissertation was to develop a more comprehensive understanding of role stressors, burnout, and resilience among teacher/coaches and non-coaching teachers. The study was divided into two phases. In phase one, 415 teachers (209 teacher/coaches, 206 non-coaching teachers) across a variety of academic …


Design, Development, And Testing Of A Conformal Power Control Interface For Thrust Vectoring Aircraft, David Rozovski Oct 2013

Design, Development, And Testing Of A Conformal Power Control Interface For Thrust Vectoring Aircraft, David Rozovski

Open Access Dissertations

Over the last five years, a new power control inceptor for tiltrotor aircraft, known as the Rotational Throttle Interface (RTI) was designed and built. Prior to the RTI, no tiltrotor inceptor had been able to simultaneously indicate both the direction and magnitude of thrust conformally. The purpose of the RTI is to provide an interface that maps to the intended vehicle response throughout ALL ranges of operation. Doing so is expected to reduce confusion that may have contributed to several tiltrotor accidents

Two tests were conducted with the RTI, one at the NASA Vertical Motion Simulator, and one at Canada's …

The Development Of Differential Object Marking In Spanish-English Bilingual Children, Mariluz Ortiz Vergara Apr 2013

The Development Of Differential Object Marking In Spanish-English Bilingual Children, Mariluz Ortiz Vergara

Open Access Theses

In monolingual development, the acquisition of differential object marking (DOM) is completed by three years of age (Rodríguez- Mondoñedo, 2008). However, among bilingual speakers, the development and use of the marker at a young age is less predictable. Spanish marks animate and specific direct objects with the preposition-a; English in contrast does not. Based on previous studies documenting transfer in areas where Spanish and English differ, it was predicted that bilingual children would experience difficulties with the use of the preposition both in matrix and left dislocated sentences (CLLD) (Montrul, 2004, Montrul & Bowles, 2009). This study tested 14 simultaneous …

The Origins Of Reading: Using The Ipad To Study 2- To 4-Year-Old's Learning Of Sound/Print/Object Relations, Ashley Catherine Vance Jan 2013

The Origins Of Reading: Using The Ipad To Study 2- To 4-Year-Old's Learning Of Sound/Print/Object Relations, Ashley Catherine Vance

Open Access Theses

This thesis looks at the origins of reading (before the age of 5) through the lens of early language development. We used an iPad to test if children can make the connection between printed words and the spoken word or their visual referent. Using a forced choice procedure, inspired by the traditional Preferential Looking Paradigm, we tested 30 children, ages 2-4 years. Results suggest that children as young as 2 years of age can indeed make spoken word-to-print connections. Specifically, by emphasizing or exaggerating text differences, we were able to get children (2-4 years of age) to correctly tap the …


International Standardization Compliance In Aviation, Tyler Brogden Spence Jan 2013

International Standardization Compliance In Aviation, Tyler Brogden Spence

The 'X It Up' Verb Construction: A Syntactic And Sociolinguistic Approach, Ryan Hubble Jan 2013

The 'X It Up' Verb Construction: A Syntactic And Sociolinguistic Approach, Ryan Hubble

Open Access Theses

This thesis focuses on a unique and, as of yet, unstudied particle verb construction in English, referred to as the `X it up' construction (e.g. I partied it up last night). Syntactic and sociolinguistic perspectives are taken to explore this phenomenon. In the area of syntax, it is proposed that the `it' in the construction is non-referential and that `it' is an (object) expletive. It is further proposed that the construction is unergative. These hypotheses are confirmed via syntactic tests, and a potential syntactic representation based on Basilico's (2008) particle verb analysis is offered as a structure in which the …


Pragmatic Transfer In Japanese Requests In Emails, Takako Noda Jan 2013

Pragmatic Transfer In Japanese Requests In Emails, Takako Noda

Open Access Theses

The speech act of request is known as a face threatening act (FTA) in the sense of Brown and Levinson (1987) and is considered a speech act that may negatively affect human relationships when it is used against cultural norms and constraints. Requests have been investigated in various languages, including English and Japanese (e.g., Hill et al., 1986; Fukushima, 1996; Gagné, 2010). Studies about interlanguage pragmatics, such as Matsuda et al. (2008) and Wada et al. (2008), showed characteristics of requests made by learners of Japanese. However, these studies all focused on the oral speech act, and there are few …

Psychopathy As A Disorder Of Communion: Investigating An Overlooked Deficit, Emily Dubose Sherman Jan 2013

Psychopathy As A Disorder Of Communion: Investigating An Overlooked Deficit, Emily Dubose Sherman

Open Access Theses

Psychopathy is a personality disorder that is robustly linked to interpersonal difficulties, delinquency, aggression, and general antisocial conduct. Previous research has explored a number of potential deficits underlying these behaviors including reduced fear, impaired emotional responding, and poor response modulation. Drawing from extant personality work that has demonstrated the importance of interpersonal antagonism as a core feature of psychopathy, the present project examines deficits in social closeness as potential core features of the disorder. This possibility was examined in 195 undergraduate students (49% male) via a multi-method approach. In addition to several psychopathy instruments, participants completed self-report measures of social …
