Value Distribution And Markets For Social Justice In Global Value Chains: Interdependence Relationships And Government Policy, Lilac Nachum

Publications and Research

Global value chains are highly prone to distortions in value distribution among participants. Their global fragmentation and relational governance undermine the effectiveness of regulatory intervention in amending these distortions. In this paper, I propose a new mechanism to administer value distribution that is in tune with the nature of these production systems. Building on interdependence theory, I suggest that interdependencies inherent in the co-specialized nature of supply chains give participants the power to alter the trade-offs between investment in social causes and economic gains and to incentivize socially desired behavior. I show how the interdependence logic manifests at varying levels …

Dipolariton Propagation In A Van Der Waals Tmdc With Ψ-Shaped Channel Guides And Buffered Channel Branches, Patrick Serafin, German Kolmakov

Publications and Research

Using a computational approach based on the driven diffusion equation for a dipolariton wave packet, we simulate the diffusive dynamics of dipolaritons in an optical microcavity embedded with a transition metal dichalcogenide (TMDC) heterogeneous bilayer encompassing a Ψ-shaped channel. By considering exciton dipolaritons, which are a three way superposition of direct excitons, indirect excitons and cavity photons; we are able to drive the dipolaritons in our system by the use of an electric voltage and investigate their diffusive properties. More precisely, we study the propagation of dipolaritons present in a MoSe₂-WS₂ heterostructure, where the dipolariton propagation is …

Gap Junction-Mediated Glycinergic Inhibition Ensures Precise Temporal Patterning In Vocal Behavior, Boris P. Chagnaud, Jonathan T. Perelmuter, Paul M. Forlano, Andrew H. Bass

Publications and Research

Precise neuronal firing is especially important for behaviors highly dependent on the correct sequencing and timing of muscle activity patterns, such as acoustic signaling. Acoustic signaling is an important communication modality for vertebrates, including many teleost fishes. Toadfishes are well known to exhibit high temporal fidelity in synchronous motoneuron firing within a hindbrain network directly determining the temporal structure of natural calls. Here, we investigated how these motoneurons maintain synchronous activation. We show that pronounced temporal precision in population-level motoneuronal firing depends on gap junction-mediated, glycinergic inhibition that generates a period of reduced probability of motoneuron activation. Super-resolution microscopy confirms …

Tech Companies And Public Health Care In The Ruins Of Covid, Shinjoung Yeo

Publications and Research

The COVID-19 pandemic has proven the cruelty of the U.S. market-driven health care system that disproportionately affects the poor. It illuminates how much a well-funded public health care system is vital for the survival of all. However, amidst the ruins of the pandemic and economic crisis, digital capitalism is driving a new round of capitalist restructuring with the health care sector at the center of capital’s new digitization push. Tech companies are at the forefront of this capitalist endeavor. Long before the outbreak, these companies and others have been cultivating the health sector into their profit-making enterprise. The pandemic has …

On The Future Of Ijsl: Trans-Collaboration And How To Overcome The Structural Constraints On Knowledge Production, Distribution And Dissemination, José Del Valle

Publications and Research

In this essay, using as a point of departure his dilemma to accept or not the invitation to be a member of IJSL’s Editorial Board, del Valle discusses the limitations that academic publishing places on scholars in the humanities and interpretive social sciences: their choice of objects and analytical protocols, and the modes of distribution and dissemination of their production. The constraints imposed by highly bureaucratized universities and publishing companies are set against the intellectual imperative to build academic fields grounded in equality and inclusion. The essay concludes with some thinly drawn goals towards more dynamic trans-collaborative forms of knowledge …

Does Rehearsal Matter? Left Anterior Temporal Alpha And Theta Band Changes Correlate With The Beneficial Effects Of Rehearsal On Working Memory, Chelsea Reichert Plaska, Kenneth Ng, Timothy M. Ellmore

Publications and Research

Rehearsal during working memory (WM) maintenance is assumed to facilitate retrieval. Less is known about how rehearsal modulates WM delay activity. In the present study, 44 participants completed a Sternberg Task with either intact novel scenes or phase-scrambled scenes, which had similar color and spatial frequency but lacked semantic content. During the rehearsal condition participants generated a descriptive label during encoding and covertly rehearsed during the delay period. During the suppression condition participants did not generate a label during encoding and suppressed (repeated “the”) during the delay period. This was easy in the former (novel scenes) but more difficult in …

Predicting Vasovagal Responses: A Model-Based And Machine Learning Approach, Theodore Raphan, Sergei B. Yakushi

Publications and Research

Vasovagal syncope (VVS) or neurogenically induced fainting has resulted in falls, fractures, and death. Methods to deal with VVS are to use implanted pacemakers or beta blockers. These are often ineffective because the underlying changes in the cardiovascular system that lead to the syncope are incompletely understood and diagnosis of frequent occurrences of VVS is still based on history and a tilt test, in which subjects are passively tilted from a supine position to 20◦ from the spatial vertical (to a 70◦ position) on the tilt table and maintained in that orientation for 10–15 min. Recently, is has been shown …

Supply Chain Viability: Conceptualization, Measurement, And Nomological Validation, Salomée Ruel, Jamal El Baz, Dmitry Ivanov, Ajay Das

Publications and Research

Supply chain viability (SCV) is an emerging concept of growing importance in operations management. This paper aims to conceptualize, develop, and validate a measurement scale for SCV. SCV is first defined and operationalized as a construct, followed by content validation and item measure development. Data have been collected through three independent samplings comprising a total of 558 respondents. Both exploratory and confirmatory factor analyses are used in a step-wise manner for scale development. Reliability and validity are evaluated. A nomological model is theorized and tested to evaluate nomological validity. For the first time, our study frames SCV as a novel …

Using Carrots Not Sticks To Cultivate A Culture Of Safeguarding In Sport, Judith L. Komaki, Yetsa A. Tuakli-Wosornu

Publications and Research

The power-driven, win-at-all-costs milieu of many sport settings can create fertile ground for athlete victimization and abuse (Roberts et al., 2020). Victory can in fact be so sovereign that abusive coaches and staff are enabled and “even rewarded. . . in the name of winning” (Armour, 2020). Athlete abuse prevention therefore requires systemic cultural change (Letourneau et al., 2014; Rhind and Owusu-Sekyere, 2017). Thus far, however, enacting this idea has eluded organizations in sport (Mountjoy et al., 2016; Harris and Terry, 2019; Kerr et al., 2019; Rhind and Owusu-Sekyere, 2020) as well as in other settings (National Academies of Sciences, …

How New England Island Residents View The Influence Of The Natural Environment In Their Lives, Nicole Kras, Jennifer Keenan

Publications and Research

While the multiple benefits of natural environments on individual’s lives have been well noted, one population that is scarcely studied in current literature are adults who live on islands in the Northeast region of the United States. This is an important population to study because these adults live in a geographical location highly immersed in natural landscapes and they are likely to have a high exposure to natural environments. This exploratory study uses participant questionnaire responses (N=51) to gain insight into how they believe the natural environment influences their lives and offers guidance for future research. Residents identified benefits and …

Bibliodiversity At The Centre: Decolonizing Open Access, Monica Berger

Publications and Research

The promise of open access for the global South has not been fully met. Publishing is dominated by Northern publishers who disadvantage Southern authors through platform capitalism and open access models requiring article processing charges to publish. The South can reclaim and decolonize open access, nurturing scholarly communities, by employing bibliodiversity, a sustainable, anticolonial ethos and practice developed in Latin America. Self-determination and locality are at the core of bibliodiversity which rejects the domination of international, English-language journal publishing. As articulated by the Jussieu Call, varied scholarly community-based, non-profit, and sustainable models for open access are integral to bibliodiversity as …

Detection Of Mutations Associated With Variants Of Concern Via High Throughput 2 Sequencing Of Sars-Cov-2 Isolated From Nyc Wastewater, Davida S. Smyth, Monica Trujillo, Kristen Cheung, Anna Gao, Irene Hoxie, Sherin Kannoly, Nanami Kubota, Michelle Markman, Kaung Myat San, Geena Sompanya, John J. Dennehy

Publications and Research

Monitoring SARS-CoV-2 genetic diversity is strongly indicated because diversifying selection may lead to the emergence of novel variants resistant to naturally acquired or vaccine-induced immunity. To date, most data on SARS-CoV-2 genetic diversity has come from the sequencing of clinical samples, but such studies may suffer limitations due to costs and throughput. Wastewater-based epidemiology may provide an alternative and complementary approach for monitoring communities for novel variants. Given that SARS-CoV-2 can infect the cells of the human gut and is found in high concentrations in feces, wastewater may be a valuable source of SARS-CoV-2 RNA, which can be deep sequenced …

The Case For Public Investment In Higher Pay For New York State Home Care Workers: Estimated Costs And Savings, Isaac Jabola-Carolus, Stephanie Luce, Ruth Milkman

Publications and Research

This report explores one potential solution to the mounting home care labor shortage in New York State: substantially raising wages for the state's home care workers. The analysis presents detailed projections, based on the best available data, of the economic effects of such an intervention, estimating the costs and benefits that would result. We find that public funding to raise home care wages would require significant resources, but those costs would be surpassed by the resulting savings, tax revenues, and economic spillover effects. The net economic gain would total at least $3.7 billion. Lifting wages would also help fill nearly …

Covid-19 And Knowledge Based Computation, Rohit J. Parikh

Publications and Research

The problem of dealing with Covid-19, until a vaccine is universally administered, is to decrease the rate of transmission while getting some social and economic activity going.

Infection passes from one person A to another person B when A is infected and B is susceptible. That is to say that B is not infected and not yet immune.

Social activity also takes place when one person interacts with another. Perhaps A is a taxpayer and B is a tax consultant. Then filing the tax return may take the form of the two of them meeting. Much can be done electronically …

Is “Just Googling It” Good Enough For First-Year Students?, Maureen Richards

Publications and Research

This study analyzes citations by first-year students to determine what content they were citing and whether it was available through the open web or the library. Examining the role of these two places as content providers for academic work fills a gap in the literature. Most of the cited works were available through the library and the open web. As the line between content providers continues to blur, these results can help academic libraries prioritize what to teach students about information literacy, where to focus collection development efforts and how to promote the discovery of library resources.

Pirnas As Modulators Of Disease Pathogenesis, Kayla J. Rayford, Ayorinde Cooley, Jelonia T. Rumph, Ashutosh Arun, Girish Rachakonda, Fernando Villalta, Maria F. Lima, Siddharth Pratap, Smita Misra, Pius N. Nde

Publications and Research

Advances in understanding disease pathogenesis correlates to modifications in gene expression within different tissues and organ systems. In depth knowledge about the dysregulation of gene expression profiles is fundamental to fully uncover mechanisms in disease development and changes in host homeostasis. The body of knowledge surrounding mammalian regulatory elements, specifically regulators of chromatin structure, transcriptional and translational activation, has considerably surged within the past decade. A set of key regulators whose function still needs to be fully elucidated are small non-coding RNAs (sncRNAs). Due to their broad range of unfolding functions in the regulation of gene expression during transcription and …

Superfluid Swimmers, German Kolmakov, Igor S. Aranson

Publications and Research

The propulsion of living microorganisms ultimately relies on viscous drag for body-fluid interactions. The self-locomotion in superfluids such as ⁴He is deemed impossible due to the apparent lack of viscous resistance. Here, we investigate the self-propulsion of a Janus (two-face) light-absorbing particle suspended in superfluid helium ⁴He (He-II). The particle is energized by the heat flux due to the absorption of light from an external source. We show that a quantum mechanical propulsion force originates due to the transformation of the superfluid to a normal fluid on the heated particle face. The theoretical analysis is supported by the …

Effects Of Structural Isomers Of Spermine On The Higher-Order Structure Of Dna And Gene Expression, Tomoki Kitagawa, Takashi Nishio, Yuko Yoshikawa, Naoki Umezawa, Tsunehiko Higuchi, Chwen-Yang Shew, Takahiro Kenmotsu, Kenichi Yoshikawa

Publications and Research

Polyamines are involved in various biological functions, including cell proliferation, differentiation, gene regulation, etc. Recently, it was found that polyamines exhibit biphasic effects on gene expression: promotion and inhibition at low and high concentrations, respectively. Here, we compared the effects of three naturally occurring tetravalent polyamines, spermine (SPM), thermospermine (TSPM), and N4-aminopropylspermidine (BSPD). Based on the single DNA observation with fluorescence microscopy together with measurements by atomic force microscopy revealed that these polyamines induce shrinkage and then compaction of DNA molecules, at low and high concentrations, respectively. We also performed the observation to evaluate the effects of these polyamine isomers …

Earliest Palaeocene Purgatoriids And The Initial Radiation Of Stem Primates, Gregory P. Wilson Mantilla, Stephen B. Chester, William A. Clemens, Jason R. Moore, Courtney J. Sprain, Brody T. Hovatter, William S. Mitchell, Wade W. Mans, Roland Mundil, Paul R. Renne

Publications and Research

Plesiadapiform mammals, as stem primates, are key to understanding the evolutionary and ecological origins of Pan-Primates and Euarchonta. The Purgatoriidae, as the geologically oldest and most primitive known plesiadapiforms and one of the oldest known placental groups, are also central to the evolutionary radiation of placentals and the Cretaceous-Palaeogene biotic recovery on land. Here, we report new dental fossils of Purgatorius from early Palaeocene (early Puercan) age deposits in northeastern Montana that represent the earliest dated occurrences of plesiadapiforms. We constrain the age of these earliest purgatoriids to magnetochron C29R and most likely to within 105–139 thousand years post- K/Pg …

Diurnal Cycle Of Passive Microwave Brightness Temperatures Over Land At A Global Scale, Zahra Sharifnezhad, Hamid Norouzi, Satya Prakash, Reginald Blake, Reze Khanbilvard

Publications and Research

Satellite-borne passive microwave radiometers provide brightness temperature (TB) measurements in a large spectral range which includes a number of frequency channels and generally two polarizations: horizontal and vertical. These TBs are widely used to retrieve several atmospheric and surface variables and parameters such as precipitation, soil moisture, water vapor, air temperature profile, and land surface emissivity. Since TBs are measured at different microwave frequencies with various instruments and at various incidence angles, spatial resolutions, and radiometric characteristics, a mere direct integration of them from different microwave sensors would not necessarily provide consistency. However, when appropriately harmonized, they can provide a …

In the public and private sectors, women continue to address multiple hurdles despite diversity and equity initiatives. Women have made tremendous strides in the workforce but are still a minority in leadership positions worldwide in multiple sectors, including nonprofit, corporate, government, medicine, education, military, and religion. In the United States women represent 60% of bachelor’s degrees earned at universities and outpace men in master’s and doctoral programs. However, a significant body of research illustrates that women’s upward mobility has been concentrated in middle management positions. Women hold 52% of all management and professional roles in the U.S. job market, including …

Triplet 23S State Of A Quantum Dot In A Magnetic Field: A 'Quantal Newtonian' First Law Study, Marlina Slamet, Viraht Sahni

Publications and Research

The triplet 2³S state of a 2-electron 2-dimensional quantum dot in a magnetic field is studied via a complementary perspective of Schrödinger-Pauli theory. The perspective is that of the individual electron via its equation of motion or ‘Quantal Newtonian’ first law. According to the law, each electron experiences an external and internal field, the sum of which vanishes. The external field is the sum of the binding and Lorentz fields. The internal field is a sum of the electron-interaction, kinetic, differential density, and internal magnetic fields. The energy is expressed in integral virial form in terms of these …
