The organization of ecological assemblages has important implications for ecosystem functioning, but little is known about how scavenger communities organize at the global scale. Here, we test four hypotheses on the factors affecting the network structure of terrestrial vertebrate scavenger assemblages and its implications on ecosystem functioning. We expect scavenger assemblages to be more nested (i.e. structured): 1) in species-rich and productive regions, as nestedness has been linked to high competition for carrion resources, and 2) regions with low human impact, because the most efficient carrion consumers that promote nestedness are large vertebrate scavengers, which are especially sensitive to human …

Higher Sensitivity Of Female Cells To Ethanol: Methylation Of Dna Lowers Cyp2e1, Generating More Ros, Carlos G. Penaloza, Mayra Cruz, Gabrielle Germain, Sidra Jabeen, Mohammad Javdan, R. A. Lockshin, Zahra Zakeri

Publications and Research

Background: Cells taken from mouse embryos before sex differentiation respond to insults according to their chromosomal sex, a difference traceable to differential methylation. We evaluated the mechanism for this difference in the controlled situation of their response to ethanol.

Methods: We evaluated the expression of mRNA for alcohol dehydrogenase (ADH), aldehyde dehyrogenases (ALDH), and a cytochrome P450 isoenzyme (Cyp2e1) in male and female mice, comparing the expressions to toxicity under several experimental conditions evaluating redox and other states.

Results: Females are more sensitive to ethanol. Disulfiram, which inhibits alcohol dehydrogenase (ADH), increases cell death in males, eliminating the sex …

Polygenic Risk Score Analysis Revealed Shared Genetic Background In Attention Deficit Hyperactivity Disorder And Narcolepsy, Nagahide Takahashi, Tomoko Nishimura, Taeko Harada, Akemi Okumura, Damee Choi, Toshiki Iwabuchi, Hitoshi Kuwabara, Shu Takagi, Yoko Nomura, Jeffrey H. Newcorn, Nori Takei, Kenji J. Tsuchiya

Publications and Research

Attention deficit hyperactive disorder (ADHD) is a highly heritable neurodevelopmental disorder, and excessive daytime sleepiness is frequently observed in ADHD patients. Excessive daytime sleepiness is also a core symptom of narcolepsy and essential hypersomnia (EHS), which are also heritable conditions. Psychostimulants are effective for the symptomatic control of ADHD (primary recommended intervention) and the two sleep disorders (frequent off-label use). However, the common biological mechanism for these disorders has not been well understood. Using a previously collected genome-wide association study of narcolepsy and EHS, we calculated polygenic risk scores (PRS) for each individual. We investigated a possible genetic association between …

Representaciones De La Identidad Neoleonesa En Los Spots De Las Campañas A La Gubernatura De Nuevo León De 2015representations Of Nuevo León’S Identity Within The Campaign Spots For The 2015 State Election, Xavier Moyssén Álvarez

Publications and Research

This article parts from the sociological model of voting behavior, according to which social characteristics deter-mine political preferences. It is proposed that regional identity, because of its socialized nature, might’ve had effects on the voting behavior of the 2015 Nuevo León election. This work isn’t focused on the result of the election, it rather intends to verify, through content analysis, the presence of elements belonging to Nuevo Leon’s identity within the campaign spots for the main candidates:Felipe de Jesús Cantú (PAN), Ivonne Álvarez García (PRI), and Jaime Heliodoro Rodríguez Calderón (independ-ent). Furthermore, we propose a theoretical explanation of the possible …

Lexical Items As Facets Of Identity In Discourse, Joseph C. M. Davis

Publications and Research

Lexical items are used in discourse not to provide objective direct reference, nor to reflect a language’s system of categorization, nor in accordance with cognitive categories, but rather to communicate different perspectives. Lexical items function as facets of identity, chosen by an author to convey a subjective message. The point is illustrated through an analysis of lexical co-reference in Antonio Tabucchi’s Donna di Porto Pim e altre storie.

The Incoherence Of Moral Relativism, Carlo Alvaro

Publications and Research

This paper is a response to Park Seungbae’s article, “Defence of Cultural Relativism”. Some of the typical criticisms of moral relativism are the following: moral relativism is erroneously committed to the principle of tolerance, which is a universal principle; there are a number of objective moral rules; a moral relativist must admit that Hitler was right, which is absurd; a moral relativist must deny, in the face of evidence, that moral progress is possible; and, since every individual belongs to multiple cultures at once, the concept of moral relativism is vague. Park argues that such contentions do not affect moral …

Rethinking Early Modern Sexuality Through Race, Mario Digangi

Publications and Research

When English Literary Renaissance launched in 1971, early modern sexuality studies did not exist. Then again, neither did the feminist, new historicist, post-colonialist, or other “political” approaches that have significantly reshaped early modern literary studies (and the humanities) over the last forty years. Yet whereas feminist and new historicist essays began thickly to populate the pages of Renaissance journals in the early 1980s, studies of sexuality—and of lesbian, gay, or queer sexualities in particular—were slow to arrive. During the 1980s, ELR published only a handful of essays that centered on sex or eroticism. The first explicit treatment of homoeroticism in …

And Still They Rise: Lessons From Students In New York City's Alternative Transfer High Schools, Mica Baum-Tuccillo, Varnica Arora, Alison Holstein, Michelle Fine

Publications and Research

And Still They Rise is the first systematic analysis of alternative transfer schools in New York City – alternative educational spaces that keep their doors open to a range of students who seek an education despite past academic struggles. The report blends a qualitative and quantitative review of 842 students’ responses to a participatory survey that asked about goals, desires, obstacles, and what they found at transfer schools. In this report we present the stories and the statistics across schools, elevating silenced stories that lay behind the misnomer “at risk." We review data that shows how deeply students appreciate their …

A Tale Of Winglets: Evolution Of Flight Morphology In Stick Insects, Yu Zeng, Connor O'Malley, Sonal Singhal, Faszly Rahim, Sehoon Park, Xin Chen, Robert Dudley

Publications and Research

The evolutionary transition between winglessness and a full-winged morphology requires selective advantage for intermediate forms. Conversely, repeated secondary wing reductions among the pterygotes indicates relaxation of such selection. However, evolutionary trajectories of such transitions are not well-characterized. The stick insects (Phasmatodea) exhibit diverse wing sizes at both interspecific and intersexual levels, and thus provide a system for examining how selection on flight capability, along with other selective forces, drives the evolution of flight-related morphology. Here, we examine variation in relevant morphology for stick insects using data from 1,100+ individuals representing 765 species. Although wing size varies along a continuous spectrum, …

Resource Ecologies, Political Economies And The Ethics Of Audio Technologies In The Anthropocene, Eliot Bates

Publications and Research

Understanding how recorded and amplified stage musics contribute towards producing the Anthropocene necessitates attending to complex transnational flows of material, capital and labor, and how they coalesce into technological objects. This is complicated by the wide array of sites, practices and knowledges involved during various stages of the production process, from initial resource extraction, to smelting, component manufacturing, technology assembly, and distribution. To develop a suitable technological ethics, and to understand what happens to environments and to human, animal and plant lifeworlds, requires one to resist abstraction and undertake a global accounting of resource ecologies with recourse to planetary-scale political …

Multivariate Analysis Of Open Field Exploration Identifies Latent Spatial And Social Behavioral Axes In Domestic Dogs, Budhaditya Chowdhury, Moira Van Staaden, Robert Huber

Advanced Science Research Center

Recent methodological advances in studying large scale animal movements have let researchers gather rich datasets from behaving animals. Often collected in small sample sizes due to logistical constraints, these datasets are however, ideal for multivariate explorations into behavioral complexity. In behavioral studies of domestic dogs, although automated data loggers have recently seen increasing use, a comprehensive framework to identify complex behavioral axes is lacking. Dog behavioral studies frequently rely on subjective ratings, despite demonstrable evidence that these are insufficient for identifying behavioral variables. Taking advantage of dogs’ innate running abilities and readily available GPS data loggers, we extracted latitude-longitude coordinates …

Sperm Storage Reduces The Strength Of The Mate-Finding Allee Effect, María V. Jiménez-Franco, Andrés Giménez, Roberto C. Rodríguez-Caro, Ana Sanz-Aguilar, Francisco Botella, Jose D. Anadon, Thorsten Wiegand, Eva Graciá

Publications and Research

Mate searching is a key component of sexual reproduction that can have important implications for population viability, especially for the mate-finding Allee effect. Interannual sperm storage by females may be an adaptation that potentially attenuates mate limitation, but the demographic consequences of this functional trait have not been studied. Our goal is to assess the effect of female sperm storage durability on the strength of the mate-finding Allee effect and the viability of populations subject to low population density and habitat alteration. We used an individual-based simulation model that incorporates realistic representations of the demographic and spatial processes of our …

Association Of Genetic Risks With Autism Spectrum Disorder And Early Neurodevelopmental Delays Among Children Without Intellectual Disability, Nagahide Takahashi, Taeko Harada, Tomoko Nishimura, Akemi Okamura, Damee Choi, Toshiki Iwabuchi, Hitoshi Kuwabara, Shu Takagai, Yoko Nomura, Nori Takei, Kenji J. Tsuchiya

Publications and Research

IMPORTANCE Autism spectrum disorder (ASD) is highly heritable, and modest contributions of common genetic variants to ASD have been reported. However, the association of genetic risks derived from common risk variants with ASD traits in children from the general population is not clear, and the association of these genetic risks with neurodevelopment in infants has not been well understood.

OBJECTIVE To test whether a polygenic risk score (PRS) for ASD is associated with neurodevelopmental progress at age 18 months and ASD traits at age 6 years among children from the general population.

Carousel: Performance And Ritual Of A Child's Play, Erik Maniscalco

Theses and Dissertations

Carousel is a series of oil paintings inspired by my seven year old

daughter, as well as my work towards becoming a childhood educator. My

aim with this project is to explore the performative and ritualistic nature of

children’s play: focusing on the creative ways children stretch and reshape

their reality through imagined play narratives. Upon the carousel’s stage,

children select a character and take part in a performed ritual. I’ve long felt

connected to the visual vocabulary found within baroque and renaissance

styles, and I am fascinated by the mixture of amusement, tradition,

religion, and distortion imbued within the …

Sinorhizobium Meliloti Changes Motility Phenotypes In The Presence Of Serum, Eris K. Bisal

Theses and Dissertations

Sinorhizobium meliloti is a nitrogen-fixing flagellated soil bacterium that engages in a mutual symbiotic relationship with the legume Medicago sativa. Using its flagella, S. meliloti is chemotactic in response to varying environmental cues thereby directed to a target, which is typically the root hairs of M. sativa. Lu et al, 2012 suggested that a signal from the plant can switch S. meliloti from a free-living flagellated microbe to a host-invading non-flagellated microbe, although this signal has not been identified. This switch is thought to occur inside curled root hairs of the plant, and after becoming non-flagellated, S. …

Learning And Motivation For Rewards In Schizophrenia: Implications For Behavioral Rehabilitation, Victoria Martin, Alexandra Brereton, Jicheng Tang

Publications and Research

Purpose of review: Impaired reward processing and amotivation are well documented in schizophrenia. We aim to review the current state of neuroimaging and behavioral research addressing components of motivational deficits in this complex and impairing syndrome. Evidence will be integrated to inform the ongoing development of effective strategies for behavioral rehabilitation. Recent findings: While striatal dopamine and aberrant reward prediction errors have been connected to amotivation in schizophrenia, they are not sufficiently full explanations of reward processing impairments. Frontal dysfunction and associated cognitive control deficits also have evidenced involvement in atypical reward prediction, learning, and valuation. Ongoing work supports the …

Altered Growth Trajectory In Children Born To Mothers With Gestational Diabetes Mellitus And Preeclampsia, Yonglin Huang, Wei Zhang, Karen Go, Kenji J. Tsuchiya, Jianzhong Hu, Daniel W. Skupski, Sheow Yun Sei, Yoko Nomura

Publications and Research

Purpose: Gestational diabetes mellitus (GDM) and preeclampsia are leading causes of mortality and morbidity in mothers and children. High childhood body mass index (BMI) is among their myriad of negative outcomes. However, little is known about the trajectory of the child BMI exposed to GDM and co-occurring preeclampsia from early to mid-childhood. This study examined the independent and joint impact of GDM and preeclampsia on childhood BMI trajectory.

Methods: A population-based sample of 356 mothers were recruited from OB/GYN clinics in New York. Their children were then followed annually from 18 to 72 months. Maternal GDM and preeclampsia status were …

Biography And Sociology: Berger On Religion As Choice Rather Than Fate, Samuel Heilman

Publications and Research

Is there a connection between biography and sociology for Peter Berger? The short answer, as demonstrated by his own memoir, Adventures of an Accidental Sociologist, is “yes.” But in his book, he traces this connection to his own arrival and training at the Graduate Faculty of the New School. I would like to suggest that the process begins earlier in his life. Known for his work on the sociology of knowledge, the examination of how “society influences thought,” I suggest an examination of how one’s biography influences thought, the environment in which Berger grew played a major role in his …

Teaching In A Flipped Classroom., Jillian Grose-Fifer

Publications and Research

In this chapter, I describe how I switched to using a flipped class model in an upper-level Sensation and Perception course, by reversing where different types of learning take place. In the flipped model, instead of introducing students to basic concepts in class, they answered guiding questions after watching videos or reading the textbook before attending class. They then spent class time working collaboratively in small groups on more challenging assignments, many of which had been homework assignments in prior (non-flipped) courses. In-class activities consisted of mini-experiments, and other student-centered hands-on learning experiences designed to foster higher-order critical thinking and …

Li Zehou: Synthesizing Kongzi, Marx, And Kant, Andrew Lambert

Publications and Research

To understand the details of Li Zehou’s work, it is helpful to first locate it within the social and historical contexts to which Li was responding. Specifically, his work can be understood as a contribution to the struggle to establish the intellectual foundations of a Chinese modernity. As China transitioned away from the long-lived dynastic system that had ended early in the twentieth century, there was intense debate in China about what forms of social and political order should take its place. Marxism emerged as the governing ideology after the Communist revolution, but this did not settle the outstanding social …
