ABSTRACT

Maiya Corral, Tyler IIams, and Dan Poppen have spent the last year developing and writing a musical based off of the short story SLEEPY by Anton Chekhov. This project is entirely student done, and ensemble created. Complete with original songs and an original script, the development of this musical has been an attempt to create new structures of leadership and democratic, community based team building.

ABSTRACT

Growing up in a rural, conservative community in Northern Idaho, the only openly LGBTQ people I knew lived as the “others.” Not wanting to be ostracised, I denied my sexuality for years until finally coming out when I was nineteen. Writing and literature were my main inspiration for accepting my queerness, so I write my story to continue that tradition.
   
Taking inspiration from a wide range of writers like Lidia Yuknavitch, Roxane Gay, Audre Lorde, and Alison Bechdel, my work focuses on a succinct and direct discussion of the body, masculinity, and sexuality. I write in a fragmented form that allows me to braid stories from different time periods together to create a complex understanding of how oppression works in a patriarchal, heteronormative culture.

ABSTRACT

Currently, surgeons in an operating room observe tissue health by manually touching the tissue and making a subjective observation about its condition. They do not have a precise, sanitary, and safe way to inspect the tissue that can give an exact result.

NeuroTouch is a hand-held device that measures the elastic modulus of biological tissues with the slightest touch to the tissue surface. NeuroTouch will eliminate subjective observation and replace it with a definitive measurement to aid in determining the severity of different health ailments. This easy to use hand-held device will be clean, accurate, and portable to ensure the successful readings of human tissue health.

ABSTRACT

Using an old fashion technique, such as woodcut printing, I study the current and ongoing interaction between foreign individuals and their exchangeable external worlds. Considering Latin-American iconography, I illustrate the development of the individual’s identity in the form of inner portraits; recreating environments from memories that commemorate their home as well as their past.

Graduate Disciplinary Research

ABSTRACT

Web-browsers have been so successful today, that they are a necessity to both private and public sectors. Reasons behind such a success are: flexibility through Turing-complete execution and powerful graphic capabilities, which are accessible through network by both trusted and untrusted sites. These capabilities lead to multiple vulnerabilities. To prevent or mitigate the probability of vulnerabilities being exploited, a successful approach can be to configure all the web-browsers by specifying multi-level-granularity and tailored high-level secure policies. Where in, the policies are transformed into configuration files and deployed to all the applicable machines in a domain. In addition, the policies should accommodate the attributes: devices, users/roles, applications, and domains of an organization. 
    
During our background study, we were not able to find any policy-oriented centralized system which had the tailored browser security settings approach, with the ability to accommodate devices, users/roles, applications, and domains. Therefore, we made it our mission to design and practically implement a system called as HiFiPol:Browser, which is a policy-oriented and multi-platform high-fidelity security policy management system for web-browsers. 
    
The endeavor of this research work is to develop a centralized system, HiFiPol:Browser, which enables: (a) the Designated Cyber-security Personnel (DCP), of an organization to secure the web-browsers of their enterprise using high-level and granular secure policy specification, which are then semi-automatically transformed into web-browser configurations, (b) the DCP to generate policies from existing web-browser configurations, and (c) remote and semi-automatic deployment of policy-instantiated web-browser configurations from centralized server to all client machines involved in the policies.

ABSTRACT

Does Repeated Texture Exposure Increase Young Children’s Preference and Intake of Yogurts?

Objective: To determine whether repeated texture exposure (RTE) increases young children’s preference and intake of different yogurt textures. 

Methods: Children aged 3-5 years (n=20) attending the University of Idaho Child Development Laboratory were offered 2-ounce portions of yogurt in six different textures: smooth, pearly, gritty, grainy, lumpy, and ropy. Flavors of each yogurt were standardized using liquid vanilla flavor (1.5ml/L) and the yogurts were manipulated with a carbohydrate to change textures. Ten taste preference activities were conducted: pre, post, and 8 exposures. Yogurt samples were measured before and after taste activities to capture intake to the nearest 0.1g. A trained researcher completed activities using a hedonic scale. 

Analysis: Descriptive analysis of the questionnaire responses, preference, and intake was conducted. A generalized linear model procedure was used to assess difference in preference and relative intake after RTE for each yogurt texture. 

Results: Children were primarily Caucasian from educated, higher SES, and who reported infrequent yogurt intake (<40% in meals/snacks). Children’s most frequent yogurt intake was at snack (n=7; 39%). Liking for gritty improved after RTE, but no other yogurt textures. Mean relative intake increased for all yogurt textures after RTE, and a significant increase was identified for gritty (p=.00), grainy (p=.00), and lumpy (p=.01). Fewer children refused to try yogurt from pre (n=4) to post (n=2) activities. 

Implications: Preliminary results indicate RTE can improve children’s intake of less familiar textures, but children may not indicate liking of these textures. Further study is needed to confirm findings and the implications for practice.

ABSTRACT

GUITAR (Graphene from the University of Idaho Thermolyzed Asphalt Reaction) is a hypothesized new Carbon allotrope discovered in department of Chemistry at the University of Idaho in 2008. Different characterization methods have been performed since then to decipher its identity. Most of those characterization data identify GUITAR as a new carbon allotrope while some of them categorize it either Graphene or Graphite. Electrochemical properties of GUITAR are very much interesting unlike the other existing carbon materials. So far, the application of GUITAR is being confirmed in energy technology, industrial and medical sensing, purification and desalination of water. More ongoing research works to explore its potential fully in collaboration with other universities being funded by different companies

Graduate Interdisciplinary Research

ABSTRACT

We used the well-known symbolic solution for the roots of a cubic polynomial to derive expressions for the dominant and subdominant eigenvalues of a 3-stage population projection matrix. As well, we obtained analytical expressions for matrix eigenvectors, complex moduli, damping ratios, sensitivities, and elasticities. The method can be applied to many wildlife life history strategies, so long as the system is fundamentally modeled with three life stages: juvenile, subadult, and adult.

In the analytical generalized characteristic equation, the demographic parameters collapse into at most three super-parameters. We show that eigenvalues and functions of eigenvalues can thus be calculated using the reduced number of super-parameters only, potentially simplifying data collection efforts for estimating growth rate and demographic quantities. We apply this method to a common 3-stage life history strategy, and show that with this system, data requirements are reduced from 4 individual pieces of field data to 2. The results presented here will be useful in population viability analysis, population recovery planning, translocation planning, and hunting and harvest management, and especially helpful for managers faced with limited sampling budgets. Additionally, the parameter reduction will aid in advancing research for constructing reliable demographic quantity confidence intervals.

ABSTRACT

Ventenata is an invasive grass species that infested range lands in the Inland Northwest, causing significant economic damage through declines in forage production. Despite its nutritional similarity to other forages such as cheatgrass in terms of crude protein content and NDF digestibility, its palatability for livestock is poor. The objective of this study was to investigate the role of texture and surface-bound microbes in determining palatability of ventanata-infested hay.

Thirty-five weaned Charolais calves were separated into five treatments according to a taste-preference study that lasted for seven days. Each animal had access to two feed bunks: one with a reference diet (mixed grass hay), and one with a treatment diet. The five treatments were: Control – Mixed grass hay used as the reference diet (CTRL); ventenata-infested hay (VENT); autoclaved mixed grass hay (AUTO-M); autoclaved ventenata-infested hay (AUTO-V); and pelleted ventenata-infested hay (PELT).

Preference between mixed-grass hay and ventenata-infested hay was calculated such that: 0% preference implies a total preference against the treatment diet; 50% preference implies an equal preference between mixed grass hay and ventenata-infested hay; and 100% preference implies a total preference for the treatment diet. Body weight gain was measured at the start and end of the experiment. Daily, intake of the reference diet and treatment diet were measured and % preference was calculated.

Among the five treatments, there was no difference in body weight gain during the 7 days on treatment. The CTRL treatment showed no difference from 50% preference, indicating that our feed preference test worked. Calves on the VENT treatment had a preference of 19%, highlighting the poor palatability of ventenata-infested hay. While autoclaving ventenata-infested hay made no difference to palatability, the PELT treatment increased preference to 50%, completely erasing the negative palatability of the ventenata-infested hay. Together, these results show the poor palatability of ventenata-infested hay may be due to texture of the hay, and ventenata’s palatability can be improved through feed processing.

ABSTRACT

The "Silent" Treatment.

Elephants are keystone in the ecosystem where they still manage to occur. Besides being incredible seed dispersers and habitat engineers, their tusks, designed for pushing trees, digging waterholes and for self-defense is, paradoxically, one of the main threats for their existence as ivory has always been an object of desire. Summed to the international demand for Ivory, conflicts between elephants and local communities are increasing the risks for the remaining elephant populations, and it is concerning from both social, political and scientific perspective. As human population grow, more natural habitats are transformed into croplands, restricting animals to fragmented areas. Elephants’ home range is large, thus constraining them in protected areas is very challenging, and crop-raiding events involving fatalities are becoming frequent as areas of human and elephant activity overlap. Finding ways to deter elephants from crossing “invisible boundaries” is challenging, and very rustic mitigation strategies have been used. But, because elephants are incredibly intelligent, they always find creative ways to get over barriers. 
    
Our idea is to create a new elephant deterrent strategy that is efficient, low maintenance, and minimally intrusive to others. We hypothesized that by exploiting elephant’s ability to communicate with infrasonic waves, we could create invisible barriers by producing high pressure waves alongside highly advanced wave-forms in the infrasonic range. Like a “rock concert” in loudness, the discomfort along with the inability to communicate near our automatically controlled and self-powered loudspeaker pillars would prevent elephants from approaching croplands, all the while being silent to the smaller creatures.
