Study of the Mechanisms of Heat Tolerance in Ivy Geraniums

Zhang, Mingshu 13 December 2014 (has links)
Ivy geranium (Pelargonium peltatum) is a heat susceptible species with its heat tolerance varying among varieties. Reactive oxygen species (ROS) and in-vivo defense systems are related to plant heat damage and heat tolerance. Application of chelated-iron has also been reported to enhance ivy geranium heat tolerance; however, the correlation of ROS, relative enzyme stability, and iron content to differences in heat tolerance in ivy geraniums is unknown. Here we show that the H2O2 content and ROS scavenging enzyme stability in ivy geranium varies with varieties and active iron is not related to heat tolerance in ivy geranium. H2O2 content in mature leaves in both heat tolerant 'Beach' and sensitive 'Butterfly' increased under heat stress, but 'Butterfly' had a relatively greater increase of this toxic compound. Catalase (CAT) activities in young leaves in both varieties decreased. In young leaves of 'Butterfly', CAT activities decreased to a level significantly lower than that in old leaves while this did not occur in 'Beach'. Superoxide dismutase (SOD) activities in 'Butterfly' young leaves were also decreased. All these phenomenon coincided with the heat tolerance differences of the two varieties. Active iron content only changed with leaf age and did not vary between varieties or treatments. Our results demonstrated that ROS scavenging ability and relative enzyme stability may indicate heat tolerance in ivy geranium and that iron deficiency was not the cause of heat damage. Cell Membrane Themostability (CMT) and Triphenyl Tetrazolium Chloride (TTC) cell viability tests are alternative, laboratory-based screening methods for screening for heat-tolerance. Both CMT and TTC tests can represent the variance in heat tolerance observed in ivy geraniums. The results of both CMT and TTC tests correlated well with plant width and growth indexes although their correlations to plant chlorosis were low. Unlike TTC, CMT strongly correlated with plant width. CMT and TTC tests are complementary laboratory-based methods that can be applied to cultivar screening for heat tolerance in ivy geraniums.

Minnie and Ivy: Minnie Moore-Willson, Ivy Stranahan, and Seminole Reform in Early Twentieth Century Florida

Joshi, Sarika 01 January 2014 (has links)
During an era when the Seminoles were little regarded in Florida, despite mass Indian reform nationwide, Minnie Moore-Willson of Kissimmee and Ivy Stranahan of Fort Lauderdale attempted to bring reform to the state. Living amongst members of the tribe, both women used their familiarity with Seminole life and practices, as well as their political and social connections, to enact change for the tribe. This was done, respectively, through the creation of reservations and attempting to increase educational and vocational opportunities for tribe members. This thesis examines the lives and activism of Minnie Moore-Willson and Ivy Stranahan over the first two decades of the twentieth century and details their attempts to reform federal and state policies towards Seminoles in Florida. It illustrates the relationships of the women with each other, the Seminoles, and political power brokers in early twentieth century Florida, and attempts to determine their motivations. In doing so, the thesis argues that, though often ignored in the historiography of Seminoles in Florida, these women served as key figures in enacting Seminole-related reforms during the era. Examining Moore-Willson and Stranahan's lives and works affords a greater understanding of how non-Seminole women conceptualized and carried out Florida reform efforts and provides a new perspective for evaluating the early stages of Florida Seminole reform and comparable efforts in other areas of the United States.

Community level impacts associated with the invasion of English ivy (Hedera spp.) in Forest Park: a look at the impacts of ivy on community composition and soil moisture

Copp, Sara Rose 11 June 2014 (has links)
Invasive species degrade ecosystems by altering natural processes and decreasing the abundance and diversity of native flora. Communities with major fluctuations in resource supply allow invasive species to exploit limiting resources making the community prone to invasion. In the Pacific Northwest, urban forests characterized with limited light and seasonally limited soil moisture are being dominated by nonnative English ivy (Hedera spp). Three observational studies were conducted in the Southern end of Forest Park within the Balch Creek Subwatershed in Portland, Oregon in order to understand 1) how English ivy changes over three growing seasons, 2) how the native understory composition responds to English ivy, 3) if the dominance of English ivy reduces soil moisture to neighboring plants, 4) how English ivy and two co-occurring native herbs (Hydrophyllum tenuipes and Vancouveria hexandra) physiologically respond to seasonal changes in soil moisture. Percent cover of the understory community was collected in both 2010 and 2013 growing seasons in 54 plots in order to understand the change in cover over time. Community response and the relationship with soil moisture was analyzed using percent cover of the understory community and associated environmental variables including soil moisture collected in 128 plots during the 2013 field season. Finally, 15 plots with co-occurring Hedera spp, H. tenuipes and V. hexandra were sampled for stomatal conductance, leaf water potential, and associated environmental variables. Results show ivy cover increases on average 14% between 2010 and 2013 while native understory cover increased on average < 1%. Once ivy forms dense cover over 44% there is a reduction of native richness, diversity and herb cover while also an increase in available soil moisture and deciduous canopy cover. There were disparate impacts to different functional groups and between species. As functional group, the herbaceous community was the most impacted by ivy invasion. The shrubs and fern community had a variable response to ivy invasion. Many of the fern and shrub species least impacted by ivy also had associations with high soil moisture and deciduous canopy cover. Finally, data suggests that ivy does not take advantage of seasonally limiting soil moisture to invade the understory community. This study indicates that English ivy is both efficient at water use and may have the ability to obtain water from distant locations throughout the forest. Once established, ivy has the ability to alter the community composition. Ivy removal and habitat restoration are essential in order to maintain and enhance biodiversity in Forest Park.

Quiero Bailar : En fallstudie om hur Ivy Queen utmanar normativa könsroller i Latinamerika och genrekonventioner i reggaetón med låten ”Quiero Bailar”

Casal, Elizeth January 2024 (has links)
In the music genre reggaetón there has been an ideal premiering hypermasculine behaviour and narratives. The female reggaetón artist Ivy Queen has been active within the genre since the early beginnings. She has spoken about the impact it had on her, working against so many men i a masculine culture. Ivy Queen has expressed that her masculine energy has served her well in situations where people have tried to put her down for being a woman. Ivy Queen is known for challenging gender norms with different artistic expressions. She has without a doubt paved the way for today's female reggaetón artists who are using classic women's rights-messages in their songs and images.  This study starts of with the theories used which are queer- and intersectional feminist-theories. Then working its way in to giving context with an introduction to history of gender in Latin America in relation to colonialism and Catholicism. Here, marianismo and machismo are important themes to introduce when the study moves toward characteristics of reggaetón and giving background in Ivy Queen.  This study will use an audiovisual model to analyze Ivy Queens song and music video "Quiero Bailar" in relation to machismo and marianismo in Latin America, and genre conventions in reggaetón.  The result of this study shows us that not only does Ivy Queen choose some parts of what critics see as problematic in reggaetón and machismo and uses it to her advantage. She also breaks down hegemonic structures through usage of queer modes in voice, image, and lyrics - while keeping the music traditionally formed.

The Form of Talk: A Study of the Dialogue Novel

Badura, Matthew David January 2010 (has links)
The “dialogue novel” is best understood as an ongoing novelistic experiment that replaces narration with dialogue, so that such basic narrative constituents as character, setting, chronology, and plot find expression not through the mediation of an external or character-bound narrative consciousness, but through the presented verbal exchange between characters. Despite sustained critical attention to the variety and “openness” of the novel form, dialogue novels have been largely ignored within English studies— treated as neither a sustained tradition within, nor a perverse manifestation of, the novel. This study seeks to address that absence and to situate the dialogue novel within narrative and novel studies. Drawing from analytic philosophy, narratology, literary theory, and the dialogue novels themselves, this study demonstrates how the unique formal texture of the dialogue novel opens onto valuable discussions about such topics as cooperative language communities, narrative desire, the power dynamics implicit in talk, and the relationship between time and narrative. Overriding these concerns is an attention to how the social nature of conversation determines how the dialogue novel represents institutional power and character agency, as well as how the dialogue novel establishes a dynamic between reader and text for the refiguration of meaning and the reconstruction of fictional worlds. Chapter One uses Paul Grice’s Cooperative Principle as a baseline for delineating how communities are formed and maintained through dialogue in Henry James’s The Awkward Age. Chapter Two considers Henry Green’s late dialogue novels alongside his novel theory and René Girard’s theory of mimetic desire to illustrate how both character and readerly desire function as imitative practices. Chapter Three considers the novels of Ivy Compton-Burnett through Aaron Fogel’s theory of “forced dialogue” to argue that dialogue’s constraints can offer liberative structure to the novel form and those who are subject to these strictures. And Chapter Four reads dialogue novels by William Gaddis and Nicholson Baker through Paul Ricoeur’s threefold mimesis and Lubomír Doležel’s possible-worlds theory to argue that the dialogue novel presents an ideal form for examining the complex intersection of formal texture and history, as well as the dialectic between narrative configuration and human time. / English

In-between Words: Late Modernist Style in the Novels of Henry Green, Ivy Compton-Burnett, Samuel Beckett, and Elizabeth Bowen

Tarnopolsky, Damian 11 December 2013 (has links)
This dissertation seeks to identify, contextualize, and explain the achievement of late modernist novelists. Late modernism represents a significant, under-examined chapter in the development of the twentieth-century novel. Unlike the majority of their peers in the decades after modernism’s height, novelists such as Henry Green, Ivy Compton-Burnett, and Elizabeth Bowen—and the best-known, Samuel Beckett—continue to innovate in prose rather than returning to realism. Unlike their predecessors, late modernists move towards doubt, eschewing the sometimes ultimately redemptive ethos of high modernism. They do so without the insistence of later postmodernists, however, or their playful mood. The result is something new, strange, and “in between.” The aims of this study are to specify the nature of late modernist style, place it in its aesthetic and historical context, and explain its significance. Each chapter is a close reading of key works by one writer: each novelist uses different techniques to add to the late modernist aesthetic, but they all move in the same direction. The first chapter explores Henry Green’s work, analyzing the textual omissions and narrative construction that make his novels so evasive. In Compton-Burnett’s case, the focus is on how dialogue creates a constantly shifting moral world in which nothing can be taken for granted. The chapter on Beckett explores repetition, both as a microscopic stylistic tool and an organizing device that prevents the text from reaching conclusion. In examining Bowen, the centre is how her syntax circles continually around various kinds of “nothingness” and self-reflexively suggests ways to explore it. This study arranges late modernist novelists in a new continuum alongside Samuel Beckett, with the result that Beckett seems less a unique genius, and the other late modernist writers seem less eccentric and more profoundly challenging. They all seek ways to go on writing when doing so seems impossible. Late modernists bring something new to the novel. Through the smallest stylistic gestures, their works make and unmake themselves, refusing to allow the reader finality. They avoid the aesthetic and philosophical associations of either consolation or utter uncertainty; late modernists matter by refusing to matter in a familiar way.

EL REGGAETÓN COMO VEHÍCULO PARA LA ENSEÑANZA DE LA VARIACIÓN LINGÜÍSTICA EN EL AULA DE ESPAÑOL L2

Huete Guerrero, Wilfredo Antonio 05 1900 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / La música popular de hace años ha cambiado, en particular el reggaetón ha tomado el mundo por asalto. Artistas que han revolucionado la escena musical, música latina, hispana que se puede escuchar por cada rincón del mundo. Sin embargo, el reggaetón tiene su propia historia, no se hizo popular de un día al otro sino ha alcanzado su nivel actual gracias a los esfuerzos de sus pioneros, los fanáticos y los artistas de hoy en día. Estos artistas reggaetoneros no son únicamente del mismo país, sino que nacieron en todas partes del mundo. Cada uno de estos artistas traen su propio español, el español de sus países, algo que expone a los oyentes a distintas variedades del español. La variedad lingüística que se puede escuchar por medio de las canciones es inmensa y es una manera auténtica de oír como realmente se habla el español en los diferentes países hispanohablantes. La cantidad de información sobre la fonética, la morfología, sintaxis o léxico que se puede aprender sobre los distintos países es incontable y sumamente importante. Información que se puede aplicar en un aula de clase L2 para enriquecer y fortalecer el aprendizaje de estos estudiantes. Empleando el reggaetón como base en las lecciones y actividades en el aula L2 se puede enseñar la variedad lingüística de cualquier país hispanohablante.
