The Quasi-Human Child: How Normative Conceptions Of Childhood Enabled Neoliberal School Reform In The United States, Debbie Sonu

Publications and Research

This paper argues that normative conceptions of the child, as a natural quasi-human being in need of guidance, enable current school reforms in the United States to directly link the child to neoliberal aims and objectives. In using Foucault’s concept of governmentality and disciplinary power, we first present how the child is constructed as a subject of the adult world, then trace how such understandings invite school policies and practices that worked on the child, rather than with the child. In order to understand how the child comes to be known and recognized as a learner, both at the intersections …

Race Matters: Recruitment & Retention: Diversifying The Library Profession, Wilma L. Jones

Publications and Research

Since the implementation of affirmative action, increasing diversity of faculty and staff continues to be a priority for many higher education institutions. However, while we recognize the value of having a diverse workforce, we need to pay more attention to recruitment and retention activities that would yield better results in outreach and opportunities for underrepresented-excluded groups who wish to become part of the library profession. How can CUNY library leaders help develop an inclusive environment: one conducive to retention of a diverse workforce, starting with the role of Search Committees, to mentors within and outside the library, to diversity professional …

Female Role Models In Bukusu Folktales: Education At The Mother’S Hearth, Namulundah Florence

Publications and Research

Folktales serve a descriptive, as well as prescriptive role, by consistently depicting societal and cultural norms. Sexist portrayals sanction the marginality of Bukusu women, particularly when these reflect prevailing gender roles and expectations. However, contests over identity and representation are as ancient as (unwritten) history. The analysis of tales From Our Mothers’ Hearths: Bukusu Folktales and Proverbs, offers a wide range of role models for women; some of which depict female agency in exacting circumstances (Florence, N., 2005. From our Mothers’ Hearths: Bukusu Folktales and Proverbs. NJ: Africa World Pres/The Red Sea Press). Further, females as narrators, protagonists, and the …

Antioxidant And Hepatoprotective Effects Of Procyanidins Fromwild Grape (Vitis Amurensis) Seeds In Ethanol-Induced Cells And Rats, Min Ji Bak, Van-Long Truong, Se-Yeon Ko, Xuan Ngan Giang Nguyen, Pajaree Ingkasupart, Mira Jun, Jin Young Shin, Woo-Sik Jeong

Publications and Research

In the present study, we characterized the antioxidant and hepatoprotective mechanisms underlying of wild grape seed procyanidins (WGP) against oxidative stress damage in ethanol-treated HepG2 cell and Sprague-Dawley (SD)-rat models. In HepG2 cells, WGP not only diminished the ethanol (EtOH, 100 mM)-induced reactive oxygen species (ROS) formation and cytochrome P450 2E1 (CYP2E1) expression, but also renovated both the activity and expression of antioxidant enzymes including catalase, superoxide dismutase, and glutathione peroxidase. Additionally, to investigate the hepatoprotective effect of WGP, rats were orally administered 10 or 50 mg/kg WGP once daily for seven days prior to the single oral administration of …

Mesenchymal Stem Cell Fate: Applying Biomaterials For Control Of Stem Cell Behavior, Hilary J. Anderson, Jugal Kishore Sahoo, Rein V. Ulijn, Matthew J. Dalby

Publications and Research

The materials pipeline for biomaterials and tissue engineering applications is under continuous development. Specifically, there is great interest in the use of designed materials in the stem cell arena as materials can be used to manipulate the cells providing control of behavior. This is important as the ability to “engineer” complexity and subsequent in vitro growth of tissues and organs is a key objective for tissue engineers. This review will describe the nature of the materials strategies, both static and dynamic, and their influence specifically on mesenchymal stem cell fate.

P2x7r-Panx1 Complex Impairs Bone Mechanosignaling Under High Glucose Levels Associated With Type-1 Diabetes, Zeynep Seref-Ferlengez, Stephanie Maung, Mitchell B. Schaffler, David C. Spray, Sylvia O. Suadicani, Mia M. Thi

Publications and Research

Type 1 diabetes (T1D) causes a range of skeletal problems, including reduced bone density and increased risk for bone fractures. However, mechanisms underlying skeletal complications in diabetes are still not well understood.We hypothesize that high glucose levels in T1D alters expression and function of purinergic receptors (P2Rs) and pannexin 1 (Panx1) channels, and thereby impairs ATP signaling that is essential for proper bone response to mechanical loading and maintenance of skeletal integrity. We first established a key role for P2X7 receptor-Panx1 in osteocyte mechanosignaling by showing that these proteins are co-expressed to provide a major pathway for flow-induced ATP release. …

Nonlinear Modal Interactions In Parity-Time (Pt) Symmetric Lasers, Li Ge, Ramy El-Ganainy

Publications and Research

Parity-time (PT ) symmetric lasers have attracted considerable attention lately due to their promising applications and intriguing properties, such as free spectral range doubling and single-mode lasing. In this work we discuss nonlinear modal interactions in these laser systems under steady state conditions, and we demonstrate that several gain clamping scenarios can occur for lasing operation in the PT -symmetric and PT -broken phases. In particular, we show that, depending on the system’s design and the external pump profile, its operation in the nonlinear regime falls into two different categories: in one the system is frozen in the PT phase …

Rapid Assessment Of “Eve Teasing” (Sexual Harassment) Of Young Women During The Commute To College In India, Mangai Natarajan

Publications and Research

Many countries have taken action in recent times to address harassment in the work place and violence in the home, but little attention has been paid to sexual harassment in public places, specifically during women’s journey to work and school. In developing countries, many more women are seeking education and employment than previously, which has increased the opportunity for sexual harassment in public places. In India, the study location, this harassment is known as “eve teasing”. Eve teasing includes cat calling, lewd remarks, and inappropriate sexual contact such as rubbing and fondling. Tolerance of such incidents could lead to more …

Spatial Engineering Of Osteochondral Tissue Constructs Through Microfluidically Directed Differentiation Of Mesenchymal Stem Cells, Stephen M. Goldman, Gilda A. Barabino

Publications and Research

The development of tissue engineered osteochondral units has been slowed by a number of technical hurdles associated with recapitulating their heterogeneous nature ex vivo. Subsequently, numerous approaches with respect to cell sourcing, scaffolding composition, and culture media formulation have been pursued, which have led to high variability in outcomes and ultimately the lack of a consensus bioprocessing strategy. As such, the objective of this study was to standardize the design process by focusing on differentially supporting formation of cartilaginous and bony matrix by a single cell source in a spatially controlled manner within a single material system. A cell-polymer solution …

Epigenetic Profiles Signify Cell Fate Plasticity In Unipotent Spermatogonial Stem And Progenitor Cells, Ying Liu, Eugenia G. Giannopoulou, Duacheng Wen, Ilaria Falciatori, Oliver Elemento, C. David Allis, Shahin Rafii, Marco Seandel

Publications and Research

Spermatogonial stem and progenitor cells (SSCs) generate adult male gametes. During in vitro expansion, these unipotent murine cells spontaneously convert to multipotent adult spermatogonial-derived stem cells (MASCs). Here we investigate this conversion process through integrative transcriptomic and epigenomic analyses. We find in SSCs that promoters essential to maintenance and differentiation of embryonic stem cells (ESCs) are enriched with histone H3-lysine4 and -lysine 27 trimethylations. These bivalent modifications are maintained at most somatic promoters after conversion, bestowing MASCs an ESC-like promoter chromatin. At enhancers, the core pluripotency circuitry is activated partially in SSCs and completely in MASCs, concomitant with loss of …

Characterization Of The Ftsz C-Terminal Variable (Ctv) Region In Z-Ring Assembly And Interaction With The Z-Ring Stabilizer Zapd In E. Coli Cytokinesis, Kuo-Hsiang Huang, Aaron Mychack, Lukasz Tchorzewski, Anuradha Janakiraman

Publications and Research

Polymerization of a ring-like cytoskeletal structure, the Z-ring, at midcell is a highly conserved feature in virtually all bacteria. The Z-ring is composed of short protofilaments of the tubulin homolog FtsZ, randomly arranged and held together through lateral interactions. In vitro, lateral associations between FtsZ protofilaments are stabilized by crowding agents, high concentrations of divalent cations, or in some cases, low pH. In vivo, the last 4–10 amino acid residues at the C-terminus of FtsZ (the C-terminal variable region, CTV) have been implicated in mediating lateral associations between FtsZ protofilaments through charge shielding. Multiple Z-ring associated proteins (Zaps), also promote …

Mediated Technologies: Locating Non-Authorial Agency In Printed And Digital Texts, Andie Silva

Publications and Research

Early modern printers, publishers and booksellers not only influenced readers to purchase particular books but continue to shape our reception of printed books today. Through title-page advertisements, prefaces and indexes, these ‘print agents’ forged unique relationships with new and returning readers. Paying attention to paratextual structures can uncover strategies for marketing new books, corralling readers and outlining new genres. A consideration of framing devices can also further our understanding of digital resources: much as print agents mediated printed books, digital humanists help reinforce the value of new technologies for the study of early modern texts, guiding users to apply new …

Titanocene−Gold Complexes Containing N‑Heterocyclic Carbene Ligands Inhibit Growth Of Prostate, Renal, And Colon Cancers In Vitro, Yiu Fung Mui, Jacob FernáNdez-Gallardo, Benelita T. Elie, Ahmed Gubran, Irene Maluenda, Mercedes Sanau, Marıá Contel

Publications and Research

We report on the synthesis, characterization, and stability studies of new titanocene complexes containing a methyl group and a carboxylate ligand (mba = −OC(O)-p-C6H4-S−) bound to gold(I)−N-heterocyclic carbene fragments through the thiolate group: [(η5-C5H5)2TiMe(μ-mba)Au(NHC)]. The cytotoxicities of the heterometallic compounds along with those of novel monometallic gold−N-heterocyclic carbene precursors [(NHC)Au(mbaH)] have been evaluated against renal, prostate, colon, and breast cancer cell lines. The highest activity and selectivity and a synergistic effect of the resulting heterometallic species was found for the prostate and colon cancer cell lines. The colocalization of both titanium and gold metals (1:1 ratio) in PC3 prostate cancer …

Affirmative Action Debates In American Government Introductory Textbooks, Sherrie L. Wallace, Marcus D. Allen

Publications and Research

Affirmative action debates remain hotly contested across America. Given how the topic is presented in respective disciplines and core textbooks, students are often misinformed. Introductory textbooks may be one of the few places where students are exposed to significant discussions on affirmative action. In this study, we examine affirmative action policy in American government introductory textbooks published between 2005 and 2014. Our study is modeled on previous, similar analyses of introductory textbooks. We use content analysis to examine the extent to which affirmative action discussions challenge or reinforce affirmative action myths and meritocracy. We conclude that textbook discussions that emphasize …

The Impact Of Academic Service Learning On Community College Students, Sharon S. Ellerton, Sandy Figueroa, Peter Fiume, Debra Greenwood

Publications and Research

Although research clearly indicates that academic service-learning provides multiple benefits to college students in baccalaureate institutions, there is less known about its impact on community college students; a population who may benefit the most from this pedagogy. Four faculty members from four different community colleges within the City University of New York incorporated service-learning into their classrooms while also maintaining control classes. Quantitative survey data on student civic engagement and college skills were collected and survey responses from those students that did, and did not, participate in service-learning were compared. The data demonstrated meaningful differences between the non-service-learners and service-learning …

Disciplines, Institutions—And Desires, Will Stockton, Mario Digangi, Ruth Mazo Karras, Melissa E. Sanchez

Publications and Research

Will Stockton: I would like to begin by asking you to consider the chiasmus under which we gather: “Desiring History and Historicizing Desire.” The chiasmus focuses our attention on the crossing of two terms, each with noun and verb forms their grammatical flexibility indexed, perhaps, to the methodological flexibility of the fields in which most of us work: early modern (here both Renaissance and late-medieval) queer and/or sexuality studies. Talk a bit about the definitions of desir/e/ing and histor/y/icizing, and the relation of these terms to the periodization and thematization of your and our work. Is defining these words more …

Reducing The Role Of The Food, Tobacco, And Alcohol Industries In Noncommunicable Disease Risk In South Africa, Peter Delobelle, David Sanders, Thandi Puoane, Nicholas Freudenberg

Publications and Research

Noncommunicable diseases (NCDs) impose a growing burden on the health, economy, and development of South Africa. According to the World Health Organization, four risk factors, tobacco use, alcohol consumption, unhealthy diets, and physical inactivity, account for a significant proportion of major NCDs. We analyze the role of tobacco, alcohol, and food corporations in promoting NCD risk and unhealthy lifestyles in South Africa and in exacerbating inequities in NCD distribution among populations. Through their business practices such as product design, marketing, retail distribution, and pricing and their business practices such as lobbying, public relations, philanthropy, and sponsored research, national and transnational …
