Reading Between The Vines: Analyzing Climate Change Adaptive Capacity In The Tulbagh Valley Wine Industry, South Africa, Jana Catherine Brady
Reading Between The Vines: Analyzing Climate Change Adaptive Capacity In The Tulbagh Valley Wine Industry, South Africa, Jana Catherine Brady
LSU Master's Theses
There is great concern across the wine industry about the effect climate change will have on wine production and quality. These worries are valid because wine grapes are sensitive to the climatological conditions in which they are grown. However, not all viticultural areas will experience climate change in the same manner and the effects of climate change could vary considerably by region. This thesis examines the potential impact of climate change on the wine industry in the already hot and dry Tulbagh Valley, South Africa. The valley has produced wine since the early 18th century, but today the valley …
Switching Of The Direction Of Reflectionless Light Propagation At Exceptional Points In Non-Pt-Symmetric Structures Using Phase-Change Materials, Yin Huang, Yuecheng Shen, M. I.N. Changjun, Georgios Veronis
Switching Of The Direction Of Reflectionless Light Propagation At Exceptional Points In Non-Pt-Symmetric Structures Using Phase-Change Materials, Yin Huang, Yuecheng Shen, M. I.N. Changjun, Georgios Veronis
Faculty Publications
We introduce a non-parity-time-symmetric three-layer structure, consisting of a gain medium layer sandwiched between two phase-change medium layers for switching of the direction of reflectionless light propagation. We show that for this structure unidirectional reflectionlessness in the forward direction can be switched to unidirectional reflectionlessness in the backward direction at the optical communication wavelength by switching the phase-change material Ge2Sb2Te5 (GST) from its amorphous to its crystalline phase. We also show that it is the existence of exceptional points for this structure with GST in both its amorphous and crystalline phases which leads to unidirectional reflectionless propagation in the forward …
Giant Salvinia, Salvinia Molesta (Salviniaceae): Evaluation Of Sub-Optimum Temperatures On Survival Of The Giant Salvinia Weevil, Cyrtobagous Salviniae (Coleoptera: Curculionidae) And Integration Of Management Practices With Aquatic Herbicides, Lauren W. Cozad
LSU Master's Theses
Salvinia molesta is one of the world’s worst aquatic weeds and has cost Louisiana nearly $7 million worth of damage and economic impact each year. While aquatic herbicides and the biological control agent, Cyrtobagous salviniae, are the most efficacious control methods, there are limitations with each technology. Therefore, studies were conducted to evaluate insect mortality at upper and lower lethal temperatures and investigate integrated pest management (IPM) with insects and herbicides. Three Louisiana populations of C. salviniae were tested to evaluate cold tolerance and found that at 0°C, the Bayou Nicholas population was 1.3- and 1.4-times more cold tolerant …

Statistical And Technical Methodologies For Duplicated Multiple-Samples Preference And Attribute Intensity Sensory Ranking Test, Kennet Mariano Carabante Ordonez
LSU Doctoral Dissertations
Ranking tests are important preference and attribute difference tools for sensory evaluation. Replicated testing is used widely to reduce the number of panelists required in other sensory methods such as discrimination. The information regarding replications sensory ranking is limited. This research evaluated important statistical and technical aspects for the development of the foundation for duplicated sensory ranking tests. Three studies were accomplished: 1) A study of nonparametric analyses on real preference ranked data; 2) a sensitivity study of two samples serving protocols for duplicated visual ranking, and 3) protocols comparison in taste. In study 1, 125 panelists ranked in duplicates …

Education As A Moral Responsibility: Foucault's Subjectivity And Confucian Cultivation, Wei Guan
Education As A Moral Responsibility: Foucault's Subjectivity And Confucian Cultivation, Wei Guan
LSU Doctoral Dissertations
The current state of education focusing on standards and assessment, according to Wu (2004), reduces education to “technical problems and individual deficiencies, subject to surveillance and quality managerial procedures” (p. 308). This work uses Foucault’s discourses of discipline and power to understand standardization as a political utility of control that makes children docile subjects through “a set of practices by which one can acquire and assimilate” (Foucault, 1988, p. 31). The process of standardization provides an ineffective grounding for achieving a worthwhile life as children are shaped as results-driven individuals (Shun & Wong, 2004). Baker (2008) believes that only through …

Mapping A Beat Repertoire: Recovering Everyday Life Performances Of The Women Of The Beat Generation, Stephanie Patricia Heath
LSU Doctoral Dissertations
Using memoir, material objects, archival research, and performance, this project locates important points of everyday life performances that are missed when the focus of Beat woman scholarship primarily seeks to integrate their literary writing into the male-centered narrative of the Beat Generation. This study retraces steps and experiences located in New York City and recovered from archives. The base narrative of the study is drawn from the memoirs How I Became Hettie Jones by Hettie Jones, Minor Characters by Joyce Johnson, and Recollections of My Life as a Woman by Diane di Prima, this project recovers the everyday life performances …
Optimization Of Overhead Irrigation In Relation To Irrigation Water Use Efficiency In The Louisiana Nursery Industry, Mark A. Wilson
Optimization Of Overhead Irrigation In Relation To Irrigation Water Use Efficiency In The Louisiana Nursery Industry, Mark A. Wilson
LSU Master's Theses
Irrigation efficiency is an essential component of nursery production in the United States. To increase productivity of Louisiana growers, a series of studies were conducted to evaluate current nursery water practices. The objectives were to determine current irrigation practices; evaluate actual water usage; and compare nursery media for water utilization. A mailed survey determined that the majority of growers used can yard production (63%), overhead irrigation (79%), had no irrigation manager (82%) and did not collect/reuse water(61%); 50% do not test/calibrate their irrigation system. Based on this information, five nurseries using overhead irrigation were selected to determine water application and …

Each text listed has an activity that was designed to meet at least one of the Common Core Standards and also includes the integration of technology and creativity in literacy instruction. With resources like the ones discussed in this article, teachers can easily tackle the …
The Neglected Readers: Differentiating Instruction For Academically Gifted And Talented Learners, Laurie A. Sharp, Patricia Clemmer
The Neglected Readers: Differentiating Instruction For Academically Gifted And Talented Learners, Laurie A. Sharp, Patricia Clemmer
The Journal of Balanced Literacy Research and Instruction
The educational needs for academically gifted and talented learners (AGTLs) are often not met in public schools as much of schools’ resources are directed towards meeting minimum performance standards. During reading instruction, AGTLs require differentiation with curriculum and instructional strategies that provide purpose and authentication of reading instruction to prevent boredom, deepen their love for reading and broaden their interests, and encourage them to move from avid reading to critical reading. The purpose of this article is to describe several research-based strategies within each of these areas to assist educators with differentiated reading instruction for AGTLs.
Creating Critical Readers And Responders Using The Common Core State Standards, Robin Jocius, Elizabeth Self, Summer Wood
Creating Critical Readers And Responders Using The Common Core State Standards, Robin Jocius, Elizabeth Self, Summer Wood
The Journal of Balanced Literacy Research and Instruction
In this article, we offer a framework that supports teachers as they create opportunities for students to become critical readers and responders. With the Critical Reader and Responder (or CR2) Framework, teachers can use their understandings of readers, texts, and tasks as entry points for planning critical literacy response activities that meet Common Core State Standards (CCSS). We provide specific examples of how elementary teachers, faced with a myriad of constraints in their instructional planning, can use the framework to meet CCSS and prepare students to be critical readers in and out of the classroom.
Using Their Own Stories: A Culturally Relevant Response To Intervention, Maggie Struck, Mark D. Vagle
Using Their Own Stories: A Culturally Relevant Response To Intervention, Maggie Struck, Mark D. Vagle
The Journal of Balanced Literacy Research and Instruction
Driven by sociocultural theories, First Author, Maggie conducted a critical action research study of her attempts to enact culturally relevant practices in a Response to Intervention (RtI) reading group. A grounded theory approach informed the analysis of her data. In this paper, we theorize three themes that were generated from the data analysis. We assert that in order to prevent RtI from becoming another unsuccessful, de-contextualized, large-scale effort, teachers and students would benefit from a culturally relevant response to intervention—a commitment to locate the contextual contingencies in which RtI is being implemented; to pay attention to what happens in the …

The account is framed chronologically from her first days of teaching through her final semester and is organized by her attention to her state’s old English/language arts core, her state’s new English/language arts core, the World-class Instructional Design Association (WIDA) standards for ELLs and finally, the Common Core Curriculum Standards (CCSS). At the end of her autobiography, the author emphasizes the lessons she learned about trying to overlay Balanced Literacy with …
Using Balanced Literacy For Delivering Culturally Relevant Pedagogy To Prepare Teachers: A 20-Year Perspective On Dreamkeepers, Nicholas Daniel Hartlep, Tatiana Joseph
Using Balanced Literacy For Delivering Culturally Relevant Pedagogy To Prepare Teachers: A 20-Year Perspective On Dreamkeepers, Nicholas Daniel Hartlep, Tatiana Joseph
The Journal of Balanced Literacy Research and Instruction
The purpose of this article is to highlight the teaching practices of two teacher educators who teach at universities in the Midwest. The authors detail the myriad ways in which they use a balanced literacy approach that is culturally relevant in their courses at Illinois State University (Normal, IL) and the University of Wisconsin-Milwaukee (Milwaukee, WI), to more effectively prepare PK-12 urban educators. The authors point to the demographic imperative, as shifting demographics continue, the need for highly effective teachers who can teach our nation’s culturally and linguistically diverse PK-12 students becomes ever more critical.

Common Core State Standards And Text Complexity: An Invitation To Learn Language In Stem Disciplines Using A Range Of Quality Literature, Rebecca M. Giles, Leah Kinniburgh
Common Core State Standards And Text Complexity: An Invitation To Learn Language In Stem Disciplines Using A Range Of Quality Literature, Rebecca M. Giles, Leah Kinniburgh
The Journal of Balanced Literacy Research and Instruction
The Common Core State Standards (CCSS) emphasize literacy learning within history/social studies, science, and technical subjects making students’ reading, writing, and language development every teacher’s concern, regardless of the discipline being taught. Books related to science, technology, engineering, and mathematics (STEM) can enhance students’ knowledge of key terms and concepts as they are revealed in authentic contexts. Students who often struggle harder to understand advanced vocabulary embedded in stories or in difficult, yet interestingly presented nonfiction gain an increased print vocabulary by reading quality STEM-aligned literature selections that exhibit the characteristics of complexity and richness of language advocated by CCSS. …
Literacy Transformation Through The Common Core: Finding Our Heartbeat, Catherine Maderazo
Literacy Transformation Through The Common Core: Finding Our Heartbeat, Catherine Maderazo
The Journal of Balanced Literacy Research and Instruction
For over a decade reading mandates have caused reading to be taught as its own subject, isolated from the other language arts, often in place of writing, content area learning, and arts integration. With the adoption and implementation of the Common Core State Standards (2010) there is potential for literacy teachers to rethink the curriculum used, methods of instruction, and how to provide individual and diverse learners with meaningful opportunities to use literacy to learn. If teachers take ownership and follow their expertise they can implement a more truly comprehensive and integrated learning experience that would prepare students for lifelong …
Building On What Children Bring: Cognitive And Sociocultural Approaches To Teaching Literacy, Catherine Compton-Lilly
Building On What Children Bring: Cognitive And Sociocultural Approaches To Teaching Literacy, Catherine Compton-Lilly
The Journal of Balanced Literacy Research and Instruction
This paper examines what is meant by “building on what children bring.” While many educators maintain that teachers need to build on what children bring to classrooms, the field of education has constructed different understandings of what this entails. This paper explores two different conceptions of what children bring: those grounded in cognitive theories about reading and those grounded in sociocultural theories of reading/literacy. I suggest that despite historical splits in the reading/literacy field that educators must balance cognitive and sociocultural considerations in order to access the vast range of knowledges that children bring to literacy learning. After exploring cognitive …

The master cytokine TGF-β mediates tissue fibrosis associated with inflammation and tissue injury. TGF-β induces fibroblast activation and differentiation into myofibroblasts that secrete extracellular matrix proteins. Canonical TGF-β signaling mobilizes Smad2 and Smad3 transcription factors that control fibrosis by promoting gene expression. However, the importance of TGF-β-Smad2/3 signaling in fibroblast-mediated cardiac fibrosis has not been directly evaluated in vivo. Here, we examined pressure overload-induced cardiac fibrosis in fibroblast- and myofibroblast-specific inducible Cre-expressing mouse lines with selective deletion of the TGF-β receptors Tgfbr1/2, Smad2, or Smad3. Fibroblast-specific deletion of Tgfbr1/2 or Smad3, but not Smad2, markedly reduced the pressure overload-induced fibrotic …

The struggle for environmental and social justice within American Indian communities is one that has been ongoing since the beginning of United States history, but the main catalyst to effect change and to promote and disperse the American Indian narrative has emerged through the power of social media in today's hyperconnected society. This article examines the power of social media to effect change, as well as a hyperconnected society's ability to empower historically disadvantaged groups that have often been misrepresented within traditional media outlets. The historic movement occurring at Standing Rock, North Dakota, and the #NoDAPL protests illustrates the capacity …

How Important Is Farm Profitability To Meat Goat Farmers?, Narayan P. Nyaupane, Jeffrey M. Gillespie, Kenneth W. Mcmillin
Faculty Publications
© 2017 American Registry of Professional Animal Scientists This study investigates United States meat goat producers’ goal structure and examines whether these goals are consistent with farm profitability. Data were collected using a nationwide mail survey, and 7 potential goals of meat goat farmers were analyzed. Results showed that “maximize profit” and “have family involved in agriculture” were the 2 most important goals, whereas “control weeds/vegetation” and “increase farm size” were the least-ranked goals. Regression results showed that farmer demographics, farm characteristics, economic indicators, and regional variables affected farmer goal structure. Results did not support a correlation between farm profitability …

© 2017 Wiley Periodicals, Inc. Integration of reproduction and metabolism is necessary for species survival. While the neural circuits controlling energy homeostasis are well-characterized, the signals controlling the relay of nutritional information to the reproductive axis are less understood. The cichlid fish Astatotilapia burtoni is ideal for studying the neural regulation of feeding and reproduction because females cycle between a feeding gravid state and a period of forced starvation while they brood developing young inside their mouths. To test the hypothesis that candidate neuropeptide-containing neurons known to be involved in feeding and energy homeostasis in mammals show conserved distribution patterns, …

The Effect Of A Crosslinking Chemical Reaction On Pattern Formation In Viscous Fingering Of Miscible Fluids In A Hele-Shaw Cell, Patrick H. Bunton, Michael P. Tullier, Eckart Meiburg, John A. Pojman
Faculty Publications
Viscous fingering can occur in fluid motion whenever a high mobility fluid displaces a low mobility fluid in a Darcy type flow. When the mobility difference is primarily attributable to viscosity (e.g., flow between the two horizontal plates of a Hele-Shaw cell), viscous fingering (VF) occurs, which is sometimes termed the Saffman-Taylor instability. Alternatively, in the presence of differences in density in a gravity field, buoyancy-driven convection can occur. These instabilities have been studied for decades, in part because of their many applications in pollutant dispersal, ocean currents, enhanced petroleum recovery, and so on. More recent interest has emerged regarding …
