Convergence Of Detrital Stoichiometry Predicts Thresholds Of Nutrient-Stimulated Breakdown In Streams, David W. P. Manning, Amy D. Rosemond, Vladislav Gulis, Jonathan P. Benstead, John S. Kominoski, John C. Maerz

Biology Faculty Publications

Nutrient enrichment of detritus‐based streams increases detrital resource quality for consumers and stimulates breakdown rates of particulate organic carbon (C). The relative importance of dissolved inorganic nitrogen (N) vs. phosphorus (P) for detrital quality and their effects on microbial‐ vs. detritivore‐mediated detrital breakdown are poorly understood. We tested effects of experimental N and P additions on detrital stoichiometry (C:N, C:P) and total and microbial breakdown (i.e., with and without detritivorous shredders, respectively) of five detritus types (four leaf litter species and wood) with different initial C : nutrient content. We enriched five headwater streams continuously for two years at different …

Expression Of Apoplast-Targeted Plant Defensin Mtdef4.2 Confers Resistance To Leaf Rust Pathogen Puccinia Triticina But Does Not Affect Mycorrhizal Symbiosis In Transgenic Wheat, Jagdeep Kaur, John Fellers, Alok Adholeya, Siva L.S. Velivelli, Kaoutar El-Mounadi, Natalya Nersesian, Thomas Clemente, Dilip Shah

Department of Agronomy and Horticulture: Faculty Publications

Rust fungi of the order Pucciniales are destructive pathogens of wheat worldwide. Leaf rust caused by the obligate, biotrophic basidiomycete fungus Puccinia triticina (Pt) is an economically important disease capable of causing up to 50 % yield losses. Historically, resistant wheat cultivars have been used to control leaf rust, but genetic resistance is ephemeral and breaks down with the emergence of new virulent Pt races. There is a need to develop alternative measures for control of leaf rust in wheat. Development of transgenic wheat expressing an antifungal defensin offers a promising approach to complement the endogenous resistance genes …

Betalains And Expression Of Antioxidant Enzymes During Development Andabiotic Stress In Rivina Humilis L. Berries, Mohammad Imtiyaj Khan, Avinash Kumar, Parvatam Giridhar

Turkish Journal of Botany

This work investigated the betalains profile and associated molecular changes during Rivina humilis L. Berry development and 1 month after inducing stress through elicitors such as salicylic acid (SA, 0.05-0.5 mM) and chitosan (CH, 0.1%-1.0%). The results showed that, during berry development, diphenol oxidase activity of tyrosinase increased, which was reflected in an exponential increase in betalains accumulation. Expression levels of a putative Rivina humilis betanidin-5-O-glucosyltransferase 2 (RhBGT2) remained unchanged, while that of antioxidant enzymes superoxide dismutase (SOD) and catalase (CAT) decreased. Treatment with SA (0.1 mM) and CH (0.5%) enhanced betalains accumulation. The pattern of betalains accumulation during berry …

Induction And Development Of Anther-Derived Gametic Embryos In Cucumber (Cucumis Sativus L.) By Optimizing The Macronutrient And Agar Concentrations In Culture Medium, Mohammad Reza Abdollahi, Samereh Najafi, Hasan Sarikhani, Sayyed Saeed Moosavi

Turkish Journal of Biology

Anther culture response of a cucumber cultivar (Beta Alpha) and three Iranian landraces of cucumber (Basmenj, Isfahani, and Korki) on MS culture media with an altered macronutrient strength (half, full, 1.5-fold, and double-strength) or various concentrations of agar (0, 3.5, 7, and 14 g L-1) was evaluated in two separate experiments. The effect of different concentrations of agar on the development of callus-derived embryos was also assessed. The androgenic potentials of various cucumbers were significantly (P < 0.01) influenced by the different macronutrient strengths and agar concentrations, although anther culture responses could vary according to the cucumber type. A doubled strength of macronutrients in culture medium resulted in the highest percentage of callogenesis (100%) in Isfahani cucumber, while use of full strength of macronutrients produced the highest percentage of embryogenic calli (83.33%) in the mentioned landrace compared to other tested forms. The maximum number of gametic embryos (1.26 and 1.23 embryos/anther) differentiated from Isfahani anther cultures on full- and half-strength MS medium, respectively. In the second experiment, the highest percentages of callogenesis were obtained in MS culture media solidified with 14 g L-1 and 7 g L-1 agar for Basmenj, with 3.5 g L-1 agar or liquid medium for Isfahani, with 7 g L-1 agar for Beta Alpha, and with 14 g L-1 agar for Korki. Culture media solidified with 7 g L-1 agar produced the highest percentage of embryogenic calli compared to other treatments. Anther culture of Korki cucumber on culture medium with 14 g L-1 agar produced the maximum number of embryos per anther compared to other cucumbers. Improved production of mature somatic embryos (torpedo and cotyledonary embryos) was achieved with higher agar concentrations (7 and 14 g L-1) for the cucumber cultivar and all landraces.

Ncaa Compliance Officers’ Perceptions On Cost Of Attendance Legislation, Thomas R. Nisonger

Master of Education in Applied Human Development Graduate Projects

Over the past few years, the NCAA has been at the forefront of providing additional benefits to student-athletes and recently the NCAA passed the cost of attendance legislation. But with this legislation comes unintended consequences in the form of a recruiting advantage for many institutions and amendments would need to be made to combat the advantage (Katz, 2015). In order to examine the possibility of a recruiting advantage from the cost of attendance legislation, the senior members of each compliance office within the American Athletic Conference were surveyed (n=11). The survey was used to gain their opinions on various topics …

Holistic Products: Designing With Time, Gifts, And Ritual, Jeremy P. Zietz

Theses and Dissertations

The notion of “you are what you buy” is an updated adage from “you are what you eat”. It makes a connection between our everyday objects and their effect on our lived experience. Looking at our relationships with our things as a type of contract, we must be intentional to shape these object contracts for our own good and health. Instead of our society’s design talents being put toward a consumerist agenda, designers must direct research and development which addresses the effects of our products holistically.

Various concepts have emerged in my creative practice which demand a deeper research and …

Theses, Dissertations and Culminating Projects

Infant mortality is the number one killer of children in the city of Detroit (Bouffard, 2014) and prematurity is the largest component, representing more than fifty percent of the current infant deaths in Detroit (Bouffard, 2014; Johnson, 2015, www.henryford.com, 2015) . Over the last two decades there has been an overwhelming amount of research in support of music therapy meeting the needs of parents and infants in the Neonatal Intensive Care Unit (Abrams, Dassler, Lee, Loewy, Silverman & Telsey, 2007; Arnon, Shapsa, Forman, Regev, Bauer, Litmanovitz, & Dolfin, 2006; Baker & Mackinlay, 2006; Cevasco, 2008; Creighton, 2011; Edwards, 2011; Loewy, …

Biochar Amendment Of Grassland Soil May Promote Woody Encroachment By Eastern Red Cedar, Ramesh Laungani, Kenneth Elgersma, Maria Juarez, Kristin Mcelligott, Tyler Kuhfahl

Faculty Work

Although carbon (C) additions to soil have been used in restoration to combat invasive species through changes in soil nitrogen (N) availability, carbon amendments to soil derived from plant material can impact soil N availability in a species-specific manner. As such, amendment-driven feedbacks on N may impact invasive species success and woody encroachment. Soil amendments like biochar, which is often added to soil to increase C storage in grassland systems, may unintentionally encourage woody encroachment into these grasslands by changing soil N dynamics. Few studies have examined biochar impacts on non-agricultural species, particularly invasive species. Woody encroachment of Eastern Red …

Legitimacy Of Local Food In The U.S. Market: Comparative Consumer Perspectives, Ali Asgari

Theses and Dissertations--Agricultural Economics

Measures of legitimacy have been described in terms of four legitimacy types, regulatory, normative, cognitive, and industry. This study provides one of the first and only empirical examinations of legitimacy, particularly with an application to local foods and sheds light on how consumers view various types of legitimacy related to local food. To apply the concept of legitimacy to local foods marketing, we take an empirical survey asking about consumer perspectives of local food, along with different shopping behavior questions.

Using cumulative logit models, results of the legitimacy models suggest that core consumers are more likely to place a high …

Impact Of Community Treatment And Neighborhood Disadvantage On Recidivism In Mental Health Courts, Woojae Han

Legacy Theses & Dissertations (2009 - 2024)

The purpose of the study is to investigate the impact of community treatment and neighborhood disadvantage on recidivism among offenders with mental health problems in Mental Health Courts (MHCs) and in traditional courts. Although treatment is believed to lead to reduced recidivism for offenders with mental illness, little research has been conducted for MHC participants. Further, neighborhood disadvantage are known to influence recidivism generally, but environmental factors have not been examined in the MHC context.

Violence And Warfare In The Late Prehistoric Southwest : A Ritual Explanation, Nia Michelle Alecksynas

Legacy Theses & Dissertations (2009 - 2024)

The last four decades of research regarding the late prehistoric American Southwest has produced abundant evidence for violence, warfare and cannibalism among the Ancestral Puebloan peoples. Most archaeologists attribute this rise in violence and subsequent abandonment of the Four Corners region to degrading environmental conditions. While ecological factors surely contributed, it is hard to accept that this alone led to the extreme mutilation of hundreds of human remains found throughout the Pueblo territory. It is proposed that increasing social complexity along with new ritual practices resulted in intense and violent attacks throughout the Pueblo expanse.

An Investigation Of The Uptake, Distribution, And Accumulation Of Lead And Other Trace Elements In Caprine Brain Tissues Using Analytical Atomic Spectrometry, Amy Joanna Steuerwald

Legacy Theses & Dissertations (2009 - 2024)

Exposure to toxic elements and dysregulation of essential elements have been implicated in neurodegenerative disorders. Despite the importance of trace elements in neurological function, little is known regarding their uptake and distribution within brain tissues. Even less is known regarding the impact of toxic metal exposure (i.e., Pb) on endogenous metals within the brain.

Development And Validation Of The Obsessive Compulsive Eating Scale, Martha Niemiec

Legacy Theses & Dissertations (2009 - 2024)

Objective: Food cravings are common and have been implicated in eating-related pathology, including binge eating, bulimia nervosa, and overweight/obesity, but difficulties in defining and quantifying the phenomenon of craving are well documented. There has been an increase in focus on the study of cognitive mechanisms underlying craving, in particular the role of intrusive thoughts; however, existing craving measures fail to fully capture these aspects of the craving experience. The present study was designed to develop a psychometrically sound measure of the obsessive-compulsive aspects of food cravings.

Prisons And Power : Carceral Coloniality In Hybrid Post-Neoliberal Venezuela, Cory Fischer-Hoffman

Legacy Theses & Dissertations (2009 - 2024)

This dissertation examines contemporary Venezuela’s dual prison system--in which half of the prison population is incarcerated in internally controlled prisons run by armed inmates, and the other half are locked up in the Bolivarian Government’s restricted “New Regime” prisons. The Venezuelan state formation is conceptualized as ‘hybrid post-neoliberal,’ demonstrating how rationalities of a liberal rentier state and neoliberalism, combined with anti-neoliberal logics all act together in competing yet co-existing ways in the post-neoliberal era, which was initiated by the 1999 Bolivarian Revolution. The central question examines the “work” of the prison in the (re)production of power relations and how policies, …

From Myplate To Mcteacher's Night : A Communication-Centered And Ecological Investigation Of Nutrition Education In Middle School : A Case Study, Crystal Lee Brandow

Legacy Theses & Dissertations (2009 - 2024)

We have an undeniable awareness about the rates of obesity in our country, and we know that rates of obesity among children and youth are higher than ever. In fact, this is predicted to be the first generation of children who will not live longer than their parents. An abundance of research has identified the challenges and the causes of childhood obesity, and even proposed solutions for addressing this growing public health concern. One of the suggested solutions, or at least preventative measures, involves schools playing an active role in combating the obesity epidemic through the provision of nutrition interventions. …
