The Roles Of Academic Libraries In Shaping Music Publishing In The Digital Age, Kimmy Szeto

Publications and Research

Libraries are positioned at the nexus of creative production, music publishing, performance, and research. The academic library community has the potential to play an influential leadership role in shaping the music publishing life cycle, making scores more readily discoverable and accessible, and establishing itself as a force that empowers a wide range of creativity and scholarship. Yet the music publishing industry has been slow to capitalize on the digital market, and academic libraries have been slow to integrate electronic music scores into their collections. In this paper, I will discuss the historical, technical, and human factors that have contributed to …

Zines For Teaching: A Survey Of Pedagogy And Implications For Academic Librarians, Susan E. Thomas

Publications and Research

Zines have begun to gain a place in higher education as pedagogical tools studied or made by students, and many academic libraries maintain zine collections. The library literature reveals little about how nonlibrarian faculty use zines in their classrooms. This paper describes the results of a survey of faculty from a range of academic disciplines and professions who teach with zines and other booklet forms. Survey results reveal the extent to which faculty zine pedagogies include collaboration with librarians and use of library collections. Faculty describe instructional activities and attitudes that many library professionals, including reference and instruction librarians, directors …

Impact Of Communication Latency On The Bus Voltage Of Centrally Controlled Dc Microgrid During Islanding, Mahmoud Saleh, Yusef Esa, Ahmed Mohamed

Publications and Research

Maintaining a sustainable and reliable source of energy to supply critical loads within a renewable energy based microgrid (MG) during blackouts is directly related to its bus voltage variations. For example, voltage variation might trigger protection devices and disconnect DERs within the MG. Centrally controlled MGs (CCMGs) type is dependent on communication. Therefore, it is very important to analyze the impact of communication networks performance degradation, such as latency, on the bus voltage of CCMGs. This paper investigates the effect of wireless communication technologies latency on the bus voltage and performance of centralized DC MGs. Two mathematical models were developed …

Participating In Democracy: Creating A Culture Of Citizenship In Primary Classrooms, Mindi Reich-Shapiro

Publications and Research

This study explores development of civic participation in children in primary (K-2) grade classrooms. It examines how teachers and administrators create a culture of democratic participation that nurtures young children's developing civic competence and embodiment of the rules, rights and responsibilities of democratic citizenship; and how young children enact these rules, rights and responsibilities within the classroom. Obstacles and challenges faced by schools in achieving these goals within the current political and socioeconomic environment that frames education in the U.S. are also explored.

Referencing Audre Lorde, Shawn(Ta) Smith-Cruz

Publications and Research

This chapter is close a reading and textual analysis of canonical texts, speeches, and archived audio recordings of Audre Lorde. It embraces Lorde’s many identities, including her identity as a librarian who chose to depart from the library as a means of survival. The author urges reference librarians to study Lorde’s example and learn from Lorde’s choice to act in a space where silence can be transformed into language and action. Acknowledgment of the limitations and opportunities that Lorde teaches us in reference service and institutional structures, may allow for librarians to move toward a realm of justice.

Lesbian Librarianship For All: A Manifesto, Shawn(Ta) Smith-Cruz

Publications and Research

This essay intends to bridge the gap between two under-appreciated communities by committing to ways that each enhances the other. The complications for being a lesbian librarian outlined here may be applied to any librarian or any lesbian by acknowledging how the two communities mirror each other in positions of marginality, struggle, and implication for silence, each active in a movement toward justice. I intend for this chapter to act as a type of autobiographical manifesto, coupled with an invitation for both lesbians and librarians to stake a claim as lesbian librarian.

A Blueprint On Self-Exploration To Justice: Introduction To “Referencing Audre Lorde” & “Lesbian Librarianship For All”, Shawn(Ta) Smith-Cruz

Publications and Research

My approach to social justice problematizes the profession by challenging the librarian to focus inwardly to a space concentrated with identity and self-exploration. To galvanize justice, the librarian may impose her or himself into the reference interaction as an element of praxis.

A Theory Of Participatory Budgeting Decision Making As A Form Of Empowerment, Dan Williams, Thad Calabese, Samuli Harju

Publications and Research

There is a growing literature concerning participatory budgeting (PB), which transfers some element of budgetary decision making from the executive or legislature to citizens. During the earlier years of development, this practice was found primarily in less developed countries. Early PB reoriented government expenditures to better focus on the needs of the populace. Substantial shares of the budget were allocated through participatory process (Souza, 2001). PB is alternative claimed as an example of participatory democracy and deliberative democracy. This paper considers issues related to these theories and further develops a distinctive budgetary theory of participatory budgeting.

Something Old, Something New: Historicizing Same-Sex Marriage Within Ongoing Struggles Over African Marriage In South Africa, Michael W. Yarbrough

Publications and Research

This article examines contemporary struggles over same-sex marriage in the daily lives of black lesbian- and gay-identified South Africans. Based primarily on 21 in-depth interviews with such South Africans drawn from a larger project on post-apartheid South African marriage, the author argues that their current struggles for relationship recognition share much in common with contemporaneous struggles of their heterosexual counterparts, and that these commonalities reflect ongoing tensions between more extended-family and more dyadic understandings of African marriage. The increasing influence of dyadic understandings of marriage, and of associated ideals of romantic love, has helped inspire same-sex marriage claims and, in …

Structure-Activity Profiling Of Alkaloid Natural Product Pharmacophores Against A Schistosoma Serotonin Receptor, Jonathan S. Marchant, Wayne W. Harding, John D. Chan

Publications and Research

Serotonin (5-HT) is an important regulator of numerous aspects of flatworm biology, ranging from neuromuscularfunctionto sexualmaturationandegglaying. Intheparasiticblood flukeSchistosomamansoni,5-HTtargets several G-protein coupled receptors (GPCRs), one of which has been demonstrated to couple to cAMP and regulate parasite movement. This receptor, Sm.5HTRL, has been successfully co-expressed in mammalian cells alongside a luminescent cAMP-biosensor, enabling pharmacological profiling for candidate anti-schistosomal drugs. Here, we have utilized this assay to perform structure-activity investigations of 143 compounds containing previously identified alkaloid natural product pharmacophores (tryptamines, aporphines and protoberberines) shown to regulate Sm.5HTRL. These experiments mapped regions of the tryptamine pharmacophore amenable and intolerant to substitution, highlighting …

Hand Issues On Scleroderma Patients, Ana Font Hernandez

Publications and Research

Based on the design of a 3D-printed spoon prototype, we surveyed scleroderma patients about the device's value. 75% of patients mentioned having problems on their hands due to scleroderma. 85% of patients said their hand form changed because of the disease. Answers to the frequency or speed of the changes provide inconclusive results. The 3D printing technology has the potential to solve specific issues scleroderma patients face in their daily lives. Nevertheless, further research is needed to fully understand how hands shape change over time.

Nanoparticles As Multimodal Photon Transducers Of Ionizing Radiation, Edwin C. Pratt, Travis M. Shaffer, Qize Zhang, Charles Michael Drain, Jan Grimm

Publications and Research

In biomedical imaging, nanoparticles combined with radionuclides that generate Cerenkov luminescence are used in diagnostic imaging, photon-induced therapies, and as activatable probes. In these applications, the nanoparticle is often viewed as a carrier inert to ionizing radiation from the radionuclide. However, certain phenomena such as enhanced nanoparticle luminescence and generation of reactive oxygen species cannot be explained by only Cerenkov luminescence interactions with nanoparticles. Herein, we report methods to examine the mechanisms of nanoparticle excitation by radionuclides, including interactions with Cerenkov luminescence, β particles, and γ radiation. We demonstrate that β scintillation contributes appreciably to excitation and reactivity in certain …

Able: Blockwise Site Frequency Spectrafor Inferring Complex Population Histories And Recombination, Champak R. Beeravolu, Michael J. Hickerson, Laurent A. F. Frantz, Konrad Lohse

Publications and Research

We introduce ABLE (Approximate Blockwise Likelihood Estimation), a novel simulation-based composite likelihood method that uses the blockwise site frequency spectrum to jointly infer past demography and recombination. ABLE is explicitly designed for a wide variety of data from unphased diploid genomes to genome-wide multi-locus data (for example, RADSeq) and can also accommodate arbitrarily large samples. We use simulations to demonstrate the accuracy of this method to infer complex histories of divergence and gene flow and reanalyze whole genome data from two species of orangutan. ABLE is available for download at https://github.com/champost/ABLE.

Human immunodeficiency virus (HIV) pre-exposure prophylaxis (PrEP) strategies with proven in vivo efficacy rely on antiretroviral drugs, creating the potential for drug resistance and complicated treatment options in individuals who become infected. Moreover, ondemand products are currently missing from the PrEP development portfolio. Griffithsin (GRFT) is a non-antiretroviral HIV entry inhibitor derived from red algae with an excellent safety profile and potent activity in vitro. When combined with carrageenan (CG), GRFT has strong activity against herpes simplex virus-2 (HSV-2) and human papillomavirus (HPV) in vitro and in vivo. Here, we report that GRFT/CG in a freeze-dried fast dissolving insert (FDI) …

A Tool For Optimizing Java 8 Stream Software Via Automated Refactoring, Raffi Khatchadourian, Yiming Tang, Mehdi Bagherzadeh, Syed Ahmed

Publications and Research

Streaming APIs are pervasive in mainstream Object-Oriented languages. For example, the Java 8 Stream API allows for functional-like, MapReduce-style operations in processing both finite and infinite data structures. However, using this API efficiently involves subtle considerations like determining when it is best for stream operations to run in parallel, when running operations in parallel can be less efficient, and when it is safe to run in parallel due to possible lambda expression side-effects. In this paper, we describe the engineering aspects of an open source automated refactoring tool called Optimize Streams that assists developers in writing optimal stream software in …

W.E.B. Dubois For The Twenty‐First Century: On Being A Scholar‐Activist In The Digital Era, Jessie Daniels

Publications and Research

W.E.B. Du Bois began his work as a scholar-activist at the dawn of the twentieth century, and this paper argues that his example has much to teach contemporary scholar-activists in the twenty-first century. In order to publish The Crisis, the magazine of the activist organization he co-founded, DuBois purchased a printing press. This meant he could own the means of his own knowledge production and foretold both the promise of what it means to be a scholar-activist in the twenty-first century and the limitations built into the current systems of knowledge production. Du Bois was also prophetic when he …

Prostaglandin D2/J2 Signaling Pathway In A Rat Model Of Neuroinflammation Displaying Progressive Parkinsonian-Like Pathology: Potential Novel Therapeutic Targets, Chuhyon Corwin, Anastasia Nikolopoulou, Allen L. Pan, Mariela Nunez-Santos, Shankar Vallabhajosula, Peter A. Serrano, John Babich, Maria E. Figueiredo-Pereira

Publications and Research

Background: Prostaglandins are products of the cyclooxygenase pathway, which is implicated in Parkinson’s disease (PD). Limited knowledge is available on mechanisms by which prostaglandins contribute to PD neurodegeneration. To address this gap, we focused on the prostaglandin PGD2/J2 signaling pathway, because PGD2 is the most abundant prostaglandin in the brain, and the one that increases the most under pathological conditions. Moreover, PGJ2 is spontaneously derived from PGD2.

Methods: In this study, we determined in rats the impact of unilateral nigral PGJ2-microinfusions on COX-2, lipocalin-type PGD2 synthase (L-PGDS), PGD2/J2 receptor 2 (DP2), and 15 hydroxyprostaglandin dehydrogenase (15-PGDH). Nigral dopaminergic (DA) and …

The Role Of Proton Transport In Gating Current In A Voltage Gated Ion Channel, As Shown By Quantum Calculations, Alisher M. Kariev, Michael E. Green

Publications and Research

Over two-thirds of a century ago, Hodgkin and Huxley proposed the existence of voltage gated ion channels (VGIC) to carry Na⁺ and K⁺ ions across the cell membrane to create the nerve impulse, in response to depolarization of the membrane. The channels have multiple physiological roles, and play a central role in a wide variety of diseases when they malfunction. The first channel structure was found by MacKinnon and coworkers in 1998. Subsequently the structure of a number of VGIC was determined in the open (ion conducting) state. This type of channel consists of four voltage sensing domains …

Oxytocin And Cancer: An Emerging Link, Ben Lerman, Trisheena Harricharran, Olorunseun O. Ogunwobi

Publications and Research

The neuropeptide hormone oxytocin, which is released from the posterior pituitary gland, is involved in a number of physiological processes. Understanding of its effects is gradually increasing due to new research in this area. While mostly recognized as a reproductive system hormone, oxytocin also regulates other organ systems such as the brain and cardiovascular system. Recently, research has focused on unraveling its involvement in cancer, and emerging evidence suggests a potential role for oxytocin as a cancer biomarker. This review summarizes observations linking oxytocin and cancer, with a special emphasis on prostate cancer, where it may promote cell proliferation. Research …

Luciferin Production And Luciferase Transcription In The Bioluminescent Copepod Metridia Lucens, Michael Tessler, Jean P. Gaffney, Jason M. Crawford, Eric Trautman, Nehaben A. Gujarati, Philip Alatalo, Vincent A. Pierbone, David F. Gruber

Publications and Research

Bioluminescent copepods are often the most abundant marine zooplankton and play critical roles in oceanic food webs. Metridia copepods exhibit particularly bright bioluminescence, and the molecular basis of their light production has just recently begun to be explored. Here we add to this body of work by transcriptomically profiling Metridia lucens, a common species found in temperate, northern, and southern latitudes. In this previously molecularly-uncharacterized species, we find the typical luciferase paralog gene set found in Metridia. More surprisingly, we recover noteworthy putative luciferase sequences that had not been described from Metridia species, indicating that bioluminescence produced by these copepods …
