Decreased Polysaccharide Feruloylation Compromises Plant Cell Wall Integrity and Increases Susceptibility to Necrotrophic Fungal Pathogens
No full textThe complexity of cell wall composition and structure determines the strength, flexibility, and function of the primary cell wall in plants. However, the contribution of the various components to cell wall integrity and function remains unclear. Modifications of cell wall composition can induce plant responses known as Cell Wall Integrity control. In this study, we used transgenic expression of the fungal feruloyl esterase AnFAE to examine the effect of post-synthetic modification of Arabidopsis and Brachypodium cell walls. Transgenic Arabidopsis plants expressing AnFAE showed a significant reduction of monomeric ferulic acid, increased amounts of wall-associated extensins, and increased susceptibility to Botrytis cinerea, compared with wild type. Transgenic Brachypodium showed reductions in monomeric and dimeric ferulic acids and increased susceptibility to Bipolaris sorokiniana. Upon infection, transgenic Arabidopsis and Brachypodium plants also showed increased expression of several defense-related genes compared with wild type. These results demonstrate a role, in both monocot and dicot plants, of polysaccharide feruloylation in plant cell wall integrity, which contributes to plant resistance to necrotrophic pathogens
Modifying the rat grimace scale for the sub-second assessment of acute pain
No full textThe goal of this study is to improve the way pain is measured in rodents. A previous 2019 publication by Dr. Nathan T. Fried utilized slow-motion videography and statistical modeling to analyze hind paw withdrawal caused by painful stimuli. Upon reanalyzing the one-second slow-motion videos from his study, there was more data in the facial features of the rat, which was not characterized in his work. A 2011 study performed in Dr. Jeffrey Mogil’s lab led to the development of the Rat and Mouse Grimace Scales (RGS, MGS), which measure facial features of pain in these rodents. However, their measurement using the Grimace Scale relied on 30 minutes of video analysis. This project further applies the RGS to the one-second slow-motion videos to assess facial rat grimace in response to different painful stimuli.Winner: Second Place, 2022 Paul Robeson Library Undergraduate Research Award
A spotlight on mental health: Nathan Filer and Michelle Thomas in conversation
No full textNathan Filer, author of 'The Heartland: Finding and Losing Schizophrenia', and journalist Michelle Thomas, author of 'My Sh*t Therapist: & Other Mental Health Stories', discussed why it is so important to question the way we talk about mental health. Bringing together insights from inside the mental health profession with stories from the people it serves, Nathan and Michelle showed the human faces that lie behind the myths and the statistics
Visualize This: The FlowingData Guide to Design, Visualization, and Statistics
No full textPractical data design tips from a data visualization expert of the modern age Data doesn?t decrease; it is ever-increasing and can be overwhelming to organize in a way that makes sense to its intended audience. Wouldn?t it be wonderful if we could actually visualize data in such a way that we could maximize its potential and tell a story in a clear, concise manner? Thanks to the creative genius of Nathan Yau, we can. With this full-color book, data visualization guru and author Nathan Yau uses step-by-step tutorials to show you how to visualize and tell stories with data. He explains how to g
Opposition vs. Opportunity: The African American Literacy Experience in America
No full textNathan Oliver examines the complex relationship between literacy, power, and liberation in African American history. The author explores how literacy became a powerful tool for liberation and enabled African Americans to confront the inconsistencies between their lived experiences and the ideals expressed in the United States’ founding documents.

Towards a secularised - transcendental style in film
No full text© 2018 Peter T. NathanTowards a secularised - transcendental style in film is a practice-led research investigation that interrogates a religious style of filmmaking known as the transcendental style in film in order to determine what it has to offer for a secular, contemporary filmmaker. Taking American author and filmmaker, Paul Schrader’s (1946 -) book titled, Transcendental Style in Film (1972) as the primary source, this enquiry begins with the unpacking of Schrader’s theory, as it pertains to the work of French director Robert Bresson (1901-1999). Aspects of complementary theories, including parametric narrative as proposed by American film theorist, David Bordwell (1947-), and French philosopher Gilles Deleuze’s (1925-1995) theory of time-image are then drawn upon to help facilitate a new, non-religious perspective of the transcendental style in film. The resulting thesis is applied to the development, production and post-production stages of a short absurd-fantasy film, The Dream of the Songstress (Nathan 2018)
Mobile Multi-media Messages (MMS): Show-don't-tell in a Communication
No full textWith its complex intersemiotic and intermedial textual configuration, the multimedia mobile message (MMS) offers a unique opportunity to apply visual semiotics tools to the theories of communication. By means of an experimental technical device used by a sample of MMS users who exchanged real image-containing messages, the author highlights the ways in which individuals play with the technical constraints of the MMS application during message production. The analysis of a set of simple messages reveals the extent to which the natural indicial tension of photography impregnates the messages, to the point of their assuming a playful dimension, through ingenious playing on meaning within the framework of a private message.MMS; semiotics; interpersonnal communication; image; text; message
Big Data, Big Libraries, Big Problems?: the 2014 LibTech Anti-talk?
No full textThe desire to create automatons is a familiar theme in human history, and during the age of the Enlightenment mechanical automatons became not only an “emblem of the cosmos”, but a symbol of man’s confidence that he would unlock nature’s greatest mysteries and fully harness her power. And yet only a century later, automatons had begun to represent human repression and servitude, a theme later picked up by writers of science fiction. Man’s confidence undeterred, the endgame of the modern scientific and technological mindset, or MSTM, seems to be increasingly coming into view with the rise of “information technology” in general and “Big data” in particular. Along with those who wield them, these can be seen as functioning together as a “mechanical muse” of sorts – surprisingly alluring – and, like a physical automaton can serve as a symbol – a microcosm – of what the MSTM sees (at the very least in practice) as the cosmic machine, our “final frontier”. And yet, individuals who unreflectively participate in these things – giving themselves over to them and seeking the powers afforded by the technology apart from technology’s rightful purposes – in fact yield to the same pragmatism and reductionism those wielding them are captive to. Thus, they ultimately nullify themselves philosophically, politically, and economically – their value increasingly being only the data concerning their persons, and its perceived usefulness. Likewise libraries, the time-honored place of, and symbol for, the intellectual flowering of the individual, will, insofar as they spurn the classical liberal arts (with the idea that things are intrinsically good, and in the case of humans, special as well) in favor of the alluring embrace of MSTM-driven “information technology” and Big data - unwittingly contribute to their irrelevance and demise as they find themselves increasingly less needed, valued, wanted. Likewise for the liberal arts as a whole, and in fact history itself, if the acid of a “science” untethered from what is, in fact, good (intrinsically), continues to gain strengt
