Faces and Places in Fashion: Steven Stipelman
No full textPart presentation, part Q&A, FIT's "Faces & Places in Fashion" lecture series is an opportunity to connect students and the public alike to the pulse of the fashion industry in an open and conversational setting.Our first remote class featured Steven Stipelman, professor of Fashion design/art at FIT since 1993. Professionally, his career goes back more than 40 years. His first job was staff illustrator at Henri Bendel, one of the most fashion forward stores of the period. He drew all the newspaper and promotional ads. His next job, and perhaps the one he is most associated with was an illustrator for Women's wear Daily and "W" for more than 25 years. He illustrated major American and European collections - designer to couture. He worked with these designers often sketching the garments before they were ever made. He learned a great deal of how the collections were created as well as construction and fabrication.Steven's work has been printed internationally and some of his clients included Lord & Taylor, Marshall Field, Estee Lauder, Orlane, Yves St Laurent cosmetics, Bill Blass, Pierre Cardin, Christian Dior, Valentino, Tuleh, Blassport, Basile and Ralph Rucci. His work has appeared in many shows and exhibitions throughout the country. In 2007, he had a one-person exhibition, "Ethereal Elegance," at the Museum at FIT. He is the author of a textbook, "Illustrating Fashion - Concept to Creation." He would describe his work as giving an impression of movement through a spontaneity of brush strokes and washes of acrylic or watercolor. He wants his figures to always have an ethereal or swan-like look, as if they were floating across the page. The drawing should project an emotion that would make you want to feel that way rather than look that way
Unified mathematical treatment of complex cascaded bipartite networks: The case of collections of journal papers
No full textIn this study, a mathematical treatment is proposed for analysis of entities and relations among entities in
complex networks consisting of cascaded bipartite networks. This treatment is applied to the case of
collections of journal papers. In this case, entities are distinguishable objects and concepts, such as papers,
references, paper authors, reference authors, paper journals, reference journals, institutions, terms, and term
definitions. Relations are associations between entity-types such as papers and the references they cite, or
paper authors and the papers they write. An entity-relationship model is introduced that explicitly shows
direct links between entity-types and possible useful indirect relations. From this a matrix formulation and
generalized matrix arithmetic are introduced that allow easy expression of relations between entities and
calculation of weights of indirect links and co-occurrence links. Occurrence matrices, equivalence
matrices, membership matrices and co-occurrence matrices are described. A dynamic model of growth
describes recursive relations in occurrence and co-occurrence matrices as papers are added to the paper
collection. Graph theoretic matrices are introduced to allow information flow studies of networks of papers
linked by their citations. Similarity calculations and similarity fusion are explained. Derivation of feature
vectors for pattern recognition techniques is presented. The relation of the proposed mathematical
treatment to seriation, clustering, multidimensional scaling, and visualization techniques is discussed. It is
shown that most existing bibliometric analysis techniques for dealing with collections of journal papers are
easily expressed in terms of the proposed mathematical treatment: co-citation analysis, bibliographic
coupling analysis, author co-citation analysis, journal co-citation analysis, Braam-Moed-vanRaan (BMV)
co-citation/co-word analysis, latent semantic analysis, hubs and authorities, and multidimensional scaling.
This report discusses an extensive software toolkit that was developed for this research for analyzing and
visualizing entities and links in a collection of journal papers. Additionally, an extensive case study is
presented, analyzing and visualizing 60 years of anthrax research through a collection of journal papers.
When dealing with complex networks that consist of cascaded bipartite networks, the treatment presented
here provides a general mathematical framework for all aspects of analysis of static network structure and
network dynamic growth. As such, it provides a basic paradigm for thinking about and modeling such
networks: computing direct and indirect links, expressing and analyzing statistical distributions of network
characteristics, describing network growth, deriving feature vectors, clustering, and visualizing network
structure and growth
Vascular consequences of passive Aβ immunization for Alzheimer's disease. Is avoidance of "malactivation" of microglia enough?
No full textAbstract The role of inflammation in Alzheimer's disease (AD) has been controversial since its first consideration. As with most instances of neuroinflammation, the possibility must be considered that activation of glia and cytokine networks in AD arises merely as a reaction to neurodegeneration. Active, healthy neurons produce signals that suppress inflammatory events, and dying neurons activate phagocytic responses in microglia at the very least. But simultaneous with the arrival of a more complex view of microglia, evidence that inflammation plays a causal or exacerbating role in AD etiology has been boosted by genetic, physiological, and epidemiological studies. In the end, it may be that the semantics of "inflammation" and glial "activation" must be regarded as too simplistic for the advancement of our understanding in this regard. It is clear that elaboration of the entire repertoire of activated microglia – a phenomenon that may be termed "malactivation" – must be prevented for healthy brain structure and function. Nevertheless, recent studies have suggested that phagocytosis of Aβ by microglia plays an important role in clearance of amyloid plaques, a process boosted by immunization paradigms. To the extent that this clearance might produce clinical improvements (still an open question), this relationship thus obligates a more nuanced consideration of the factors that indicate and control the various activities of microglia and other components of neuroinflammation.</p

Book Review: We Had to Get Out of That Place: A Memoir of Redemption and Betrayal in Vietnam
No full textAuthor: Steven Grzesik
Reviewed by Dr. Wylie W. Johnson, chaplain, US Army War College Class of 2010
Dr. Wylie W. Johnson reviews Vietnam War veteran Steven Grzesik’s memoir that, as Johnson explains, shows the effects of “the Army’s institutional policies” and how “[u]nit cohesiveness begins with senior leadership.” Grzesik’s personal experiences and the “isolation, abuse, and sacrifice of individual replacements” (which Johnson identifies as important themes in the book) provide a valuable perspective on “the imperative of caring for soldiers.”https://press.armywarcollege.edu/parameters_bookshelf/1070/thumbnail.jp
Understanding Atrocities: Remembering, Representing and Teaching Genocide
No full textUnderstanding Atrocities is a wide-ranging collection of essays bridging scholarly and community-based efforts to understand and respond to the global, transhistorical problem of genocide. The essays in this volume investigate how evolving, contemporary views on mass atrocity frame and complicate the possibilities for the understanding and prevention of genocide. The contributors ask, among other things, what are the limits of the law, of history, of literature, and of education in understanding and representing genocidal violence? What are the challenges we face in teaching and learning about extreme events such as these, and how does the language we use contribute to or impair what can be taught and learned about genocide? Who gets to decide if it's genocide and who its victims are? And how does the demonization of perpetrators of atrocity prevent us from confronting the complicity of others, or of ourselves? Through a multi-focused and multidisciplinary investigation of these questions, Understanding Atrocities demonstrates the vibrancy and breadth of the contemporary state of genocide studies.
