Publications and Research

These are public comments submitted by National Center for the Study of Collective Bargaining in Higher Education and the Professions, Hunter College, City University of New York in response to a proposed NLRB rule that would exclude student employees from coverage under the National Labor Relations Act (NLRA). The comments include information and data showing that the proposed rule would exclude from NLRA coverage 81,390 graduate assistants working at 518 private institutions in occupations that other federal agencies treat as distinct from the classification of graduate student. The comments also present a half-century of history and legal precedent concerning collective …

Graded Quivers, Generalized Dimer Models And Toric Geometry, Sebastián Franco, Azeem Hasan

Publications and Research

The open string sector of the topological B-model on CY (m+2)-folds is described by m-graded quivers with superpotentials. This correspondence extends to general m the well known connection between CY (m+2)-folds and gauge theories on the world-volume of D(5-2m)-branes for m = 0, ..., 3. We introduce m-dimers, which fully encode the m-graded quivers and their superpotentials, in the case in which the CY (m+2)-folds are toric. Generalizing the well known m = 1,2 cases, m-dimers significantly simplify the connection between geometry and m-graded quivers. A key …

Residential Household Yard Care Practices Along Urban-Exurban Gradients In Six Climatically-Diverse U.S. Metropolitan Areas, Dexter H. Locke, Colin Polsky, J. Morgan Grove, Peter M. Groffman, Kristen C. Nelson, Kelli L. Larson, Jeannine Cavender-Bares, James B. Heffernan, Rinku Roy Chowdhury, Sarah E. Hobbie, Neil D. Bettez, Sharon J. Hall, Christopher Neill, Laura Ogden, Jarlath O'Neil-Dunne

Publications and Research

Residential land is expanding in the United States, and lawn now covers more area than the country’s leading irrigated crop by area. Given that lawns are widespread across diverse climatic regions and there is rising concern about the environmental impacts associated with their management, there is a clear need to understand the geographic variation, drivers, and outcomes of common yard care practices. We hypothesized that 1) income, age, and the number of neighbors known by name will be positively associated with the odds of having irrigated, fertilized, or applied pesticides in the last year, 2) irrigation, fertilization, and pesticide application …

Suicide Among Persons Who Entered Same-Sex And Opposite-Sex Marriage In Denmark And Sweden, 1989–2016: A Binational, Register-Based Cohort Study, Annette Erlangsen, Sven Drefahl, Ann Haas, Charlotte Bjorkenstam, Merete Nordentoft, Gunnar Andersson

Publications and Research

Background

People belonging to sexual minority groups have higher levels of suicidality than heterosexuals. However, findings regarding suicide death are sparse. Using unique national data from two countries, we investigated whether individuals entering a same-sex marriage (SSM), a proxy group of sexual minority individuals, had higher suicide rates than those entering opposite-sex marriage (OSM).

Methods

A cohort study of all males and females who entered an SSM (n=28 649) or OSM (n=3 918 617) in Denmark and Sweden during 1989–2016 was conducted. Incidence rate ratios (IRRs) for suicide were calculated using adjusted Poisson regression models.

Results

In total, 97 suicides …

Planck's And Callendar's Blackbody Radiation Formulas And Their Fitness To Experimental Data, Max Tran

We use R and Maxima to analyze their fitness on coordinating experimental data and indicate some limitations with experiments in this area.

Scythes, Sickles And Other Blades: Defining The Diversity Of Pectoral Fin Morphotypes In Pachycormiformes, Jeff J. Liston, Anthony E. Maltese, Paul H. Lambers, Dominique Delsate, William E.H. Harcourt-Smith, Anneke H. Van Heteren

Publications and Research

The traditional terminology of ‘scythe’ or ‘sickle’ shaped is observed to be flawed as an effective descriptor for pectoral fin shape in pachycormids. The diversity of pachycormid pectoral fin shapes is assessed across the 14 recognised genera that preserve complete pectoral fins, and improved terms are defined to more effectively describe their form, supported by anatomical observation and aspect ratio analysis of individual fins, and corroborated by landmark analysis. Three clear and distinct pectoral fin structural morphotypes emerge (falceform, gladiform, falcataform), reflecting a diversity of pachycormid lifestyles throughout the Mesozoic, from agile pursuit predator to slow-cruising suspension feeder.

Public Health Research Priorities To Address Female Genital Mutilation Or Cutting In The United States, Holly G. Atkinson, Deborah Ottenheimer, Ranit Mishori

Publications and Research

Female genital mutilation or cut- ting (FGM/C), an age-old tradition that is still widely practiced around the world, is gaining recognition as an important public health issue in the United States. Increasingly, because of migration, women and girls affected by FGM/C have become members of host communities where the practice is not culturally acceptable.

According to recent conservative estimates, more than 513 000 immigrant women and girls living in the United States have undergone or are at risk for FGM/C, a significant increase from the 1990 estimate of 168 000. The arrests of physicians in Michigan in 2017 for performing …

“We Cannot Imagine”: Us Preservice Teachers’ Othering Of Trans And Gender Creative Student Experiences, Elizabeth E. Blair, Sherry L. Deckman

Publications and Research

Research suggests that teachers are not meeting the needs of trans and gender creative students. Thus, we ask: How do US preservice teachers (PSTs) discursively construct the experiences of trans and gender creative students? How are these constructions informed by and reinscribe broader gender normativities in educational contexts? We analyzed 549 PST authored, online discussion posts from an educational foundations course, finding PSTs lacked familiarity with and engaged in rhetorical distancing from trans and gender creative student experiences suggesting barriers to empathy that may obstruct teacher-student relationships and promotion of equity, which teacher education is called to address.

Beyond Europeanization: The Politics Of Scale And Positionality In Lithuania’S Alternative Food Networks, Renata Blumberg, Diana Mincyte

Publications and Research

This article brings geographical insights to understanding the Europeanization of agri-food politics in new European Union member states. Most literature on agri-food policy and law in the European Union has conceptualized policy making and implementation as an institutional process involving multiple levels of governance. In this perspective, Europeanization is understood as a process through which stakeholders formulate, negotiate, and implement legal principles and procedures across various institutions at different levels of governance. By employing the conceptual tools developed in geographical research, we contribute a spatial and historical dimension to these studies. Our analysis shows how the politics of scale and …

Rasp 4: Ancestral State Reconstruction Tool For Multiple Genes And Characters, Yan Yu, Christopher Blair, Xingjin He

Publications and Research

With the continual progress of sequencing techniques, genome-scale data are increasingly used in phylogenetic studies. With more data from throughout the genome, the relationship between genes and different kinds of characters is receiving more attention. Here, we present version 4 of RASP, a software to reconstruct ancestral states through phylogenetic trees. RASP can apply generalized statistical ancestral reconstruction methods to phylogenies, explore the phylogenetic signal of characters to particular trees, calculate distances between trees, and cluster trees into groups. RASP 4 has an improved graphic user interface and is freely available from http://mnh.scu.edu.cn/soft/blog/RASP (program) and https://github.com/sculab/RASP (source code).

Spatio-Temporal Variability Of Drought In Pakistan Using Standardized Precipitation Evapotranspiration Index, Shoaib Jamro, Ghulam Hussain Dars, Kamran Ansari, Nir Krakauer

Publications and Research

Pakistan is among the top ten countries adversely affected by climate change. More specifically, there is concern that climate change may cause longer and severer spells of droughts. To quantify the change in the characteristics of droughts in Pakistan over the years, we have evaluated spatio-temporal trends of droughts in Pakistan over the period 1902–2015 using Standardized Precipitation Evapotranspiration Index (SPEI). Additionally, the Spatial “K” luster Analysis using Tree Edge Removal (SKATER) method was employed to regionalize droughts into five contiguous zones. The run theory was then applied to each zone to identify drought events and characterize them in terms …

The Concurrent Decline Of Soil Lead And Children’S Blood Lead In New Orleans, Howard W. Mielke, Christopher R. Gonzales, Eric T. Powell, Mark A. S. Laidlow, Kenneth J. Berry, Paul W. Mielke Jr., Sara Perl Egendorf

Publications and Research

Lead (Pb) is extremely toxic and a major cause of chronic diseases worldwide. Pb is associated with health disparities, particularly within low-income populations. In biological systems, Pb mimics calcium and, among other effects, interrupts cell signaling. Furthermore, Pb exposure results in epigenetic changes that affect multigenerational gene expression. Exposure to Pb has decreased through primary prevention, including removal of Pb solder from canned food, regulating lead-based paint, and especially eliminating Pb additives in gasoline. While researchers observe a continuous decline in children’s blood lead (BPb), reservoirs of exposure persist in topsoil, which stores the legacy dust from leaded gasoline and …

Racial And Ethnic Disparities In Palliative Care: A Systematic Scoping Review, Daniel Gardner, Meredith Doherty, Gleneara Bates, Aliza Koplow, Sarah C. Johnson

Publications and Research

Despite the advances and spread of palliative care programs, communities of color remain significantly underserved. Although these disparities are widely known, there is a marked lack of empirical evidence. The authors conducted a systematic scoping review that synthesized the literature since 2000 about racial and ethnic disparities in palliative and end-of-life care. We searched PubMed, Medline, SocIndex, CINAHL, Social Work Abstracts, and PsycINFO, using search terms including palliative care or end-of-life care, disparities or barriers or utilization, and race or ethnicity or African American or Hispanic. Findings lend support to extant literature that social environmental barriers and disparities distinctly affect …

Venom Diversity And Evolution In The Most Divergent Cone Snail Genus Profundiconus, Guilia Fassio, Maria Vittoria Modica, Lou Mary, Paul Zaharias, Alexander E. Fedosov, Juliette Gorson, Yuri I. Kantor, Mandë E. Holford, Nicolas Puillandre

Publications and Research

Profundiconus is the most divergent cone snail genus and its unique phylogenetic position, sister to the rest of the family Conidae, makes it a key taxon for examining venom evolution and diversity. Venom gland and foot transcriptomes of Profundiconus cf. vaubani and Profundiconus neocaledonicus were de novo assembled, annotated, and analyzed for differential expression. One hundred and thirty-seven venom components were identified from P. cf. vaubani and 82 from P. neocaledonicus, with only four shared by both species. The majority of the transcript diversity was composed of putative peptides, including conotoxins, profunditoxins, turripeptides, insulin, and prohormone-4. However, there were also …

Innovative Collaborations: Social Work Student Interns At Public Libraries, Sarah C. Johnson

Publications and Research

While the collaborative trend among professional social workers and librarians is garnering much-deserved attention, literature about social work students partnering with public libraries is virtually non-existent. In fact, there are at least 73 partnerships yet a scarcity of academic literature addresses social work interns within public libraries. While there are students at Canadian libraries, this research focuses on the bulk of known partnerships based in the United States. Emerging from a mix of interviews and public resources, the author’s inquiry fosters this call to action: Social work educators must initiate interagency collaboration with libraries in order for students to expand …

The United Nations Declaration On The Rights Of Peasants And Other People Working In Rural Areas, Marc Edelman, Priscilla Claeys

In December 2018, the United Nations adopted the Declaration on the Rights of Peasants and Other People Working in Rural Areas. UNDROP is the product of 17 years of struggle by La Via Campesina, other transnational agrarian movements and allies that included NGOs, states, UN mandate holders, and academics. It recognises the dignity of rural populations, their contributions to global food production, and their ‘special relationship’ to land, water and nature, as well as their vulnerabilities to eviction, hazardous working conditions and political repression. It reiterates rights protected in other instruments and sets new standards for individual and collective rights …

Mean Propulsive Velocity Is A Viable Method For Adjusting The Resistance-Training Load At Moderate Altitude, Lara Rodríguez-Zamora, Paulino Padial, Brad Jon Schoenfeld, Belén Feriche

Publications and Research

We examined the viability of using mean propulsive velocity (MPV) to adjust the load in the countermovement jump (CMJ) at moderate altitude. Twenty-four volunteers were assigned to a 4-week power-oriented resistance training (R_T) program in either normoxia (N, 690m) or intermittent hypobaric hypoxia (IH, 2,320m). The load was adjusted to maintain execution velocity of CMJ at 1m·s⁻¹ of MPV. Relative peak power output (P_rel), and percentage of velocity loss throughout the sets (VL) were determined for each session. The internal load was measured by the rating of perceived exertion (RPE). The absolute load lifted was …

Invertebrate Retinal Progenitors As Regenerative Models In A Microfluidic System, Caroline D. Pena, Stephanie Zhang, Robert Majeska, Tadmiri Venkatesh, Maribel Vazquez

Publications and Research

Regenerative retinal therapies have introduced progenitor cells to replace dysfunctional or injured neurons and regain visual function. While contemporary cell replacement therapies have delivered retinal progenitor cells (RPCs) within customized biomaterials to promote viability and enable transplantation, outcomes have been severely limited by the misdirected and/or insuffcient migration of transplanted cells. RPCs must achieve appropriate spatial and functional positioning in host retina, collectively, to restore vision, whereas movement of clustered cells differs substantially from the single cell migration studied in classical chemotaxis models. Defining how RPCs interact with each other, neighboring cell types and surrounding extracellular matrixes are critical to …

CS Visions highlights the importance of core values when it comes to computer science education. Understanding different reasons for teaching computer science isn’t just important so that we can get other people to care about CS, they should also shape what computer science education efforts look like - who gets opportunities to learn, what kinds of things get taught and in what ways. Our values should be expressed in our practice.

Snap At The Community Scale: How Neighborhood Characteristics Affect Participation And Food Access, Nevin Cohen

Publications and Research

Cities are spatially diverse, with enclaves of particular demo- graphic groups, clusters of businesses, and pockets of low-income individuals living amid affluence.

This essay presents data from New York City to illustrate the importance of measuring and addressing neighborhood characteristics that affect Sup- plemental Nutrition Assistance Program (SNAP) participation and the purchasing power of SNAP benefits: pockets of “eligible-but-not-enrolled” in- dividuals, proximity between SNAP participants and jobs, and variations in food prices across neighborhoods.

It concludes with 5 exam- ples of how addressing these community-scale issues can increase SNAP participation and food access.

Nuclear Tau, P53 And Pin1 Regulate Parn-Mediated Deadenylation And Gene Expression, Jorge Baquero, Sophia Varriano, Martha Ordonez, Pawel Kuczaj, Michael R. Murphy, Gamage Aruggoda, Devon Lundine, Viktoriya Morozova, Ali Elhadi Makki, Alejandra Del C. Alonso, Frida E. Kleiman

Publications and Research

While nuclear tau plays a role in DNA damage response (DDR) and chromosome relaxation, the mechanisms behind these functions are not fully understood. Here, we show that tau forms complex(es) with factors involved in nuclear mRNA processing such as tumor suppressor p53 and poly(A)-specific ribonuclease (PARN) deadenylase. Tau induces PARN activity in different cellular models during DDR, and this activation is further increased by p53 and inhibited by tau phosphorylation at residues implicated in neurological disorders. Tau’s binding factor Pin1, a mitotic regulator overexpressed in cancer and depleted in Alzheimer’s disease (AD), also plays a role in the activation of …

Spatial Upscaling Of Forest Response To Drought, Wei Fang, Peipei Xu, Tao Zhao, Xiang Zhao, Hui Luo, George Hendrey, Chuixiang Yi

Publications and Research

We have integrated the observational capability of satellite remote sensing with plot-scale tree ring data to up-scale the evaluation of forest responses to drought. Satellite data, such as Normalized Difference Vegetation Index (NDVI), can provide a spatially continuous measure with limited temporal coverage, while tree Ring Width Index (RWI) provides accurate assessment with much longer time series local scales. Here, we explored the relationship between RWI and NDVI of three dominant species in the Southwestern United States (SWUS), and predicted RWI spatial distribution from 2001 to 2017 based on MODIS 1-km resolution NDVI data with stringent quality control. We detected …

Tio2/S-Doped Carbons Hybrids: Analysis Of Their Interfacial And Surface Features, Teresa Bandosz, Alfonso Policicchio, Marc Florent, Po S. Poon, Juan Matos

Publications and Research

Hybrids containing approximately equal amounts of P25 TiO2 and S-doped porous carbons were prepared using a water-based slurry mixing method. The materials were extensively characterized by adsorption of nitrogen, potentiometric titration, thermal analysis in air and in helium, XRD, XPS and SEM. The collected results showed the significant blockage of carbon micropores by TiO2 particles deposited on their outer surface. The formation of a new interface, especially for the S-rich samples, might also contribute to the porosity alteration. Analysis of surface chemistry suggested the presence of Ti-S bonds with an involvement of sulfur from thiophenic species in the carbon phase. …
