O Tonalismo Como Força Colonizadora Na África, Kofi Agawu, José H. Padovani

Publications and Research

Resumo do tradutor: No ensaio, Kofi Agawu aborda a relação entre o tonalismo – entendido como “sistema hierarquicamente organizado de relações entre alturas” – e a música africana. A partir de diferentes exemplos e em diálogo com contribuições dos estudos decoloniais e da etnomusicologia, Agawu desenvolve uma interpretação crítica que busca compreender como aspectos da imaginação musical africana responderam à violência colonial imposta a partir de uma linguagem harmônica estrangeira. Após três momentos, em que busca respectivamente expor (1) aspectos do tonalismo na música africana da atualidade, (2) aspectos do pensamento tonal africano pré-colonial e (3) elaborações composicionais de criadores …

Dom Degradation By Light And Microbes Along The Yukon River‑Coastal Ocean Continuum, Brice K. Grunert, Maria Tzortziou, Patrick Neale, Alana Menendez, Peter Hernes

Publications and Research

The Arctic is experiencing rapid warming, resulting in fundamental shifts in hydrologic connectivity and carbon cycling. Dissolved organic matter (DOM) is a significant component of the Arctic and global carbon cycle, and significant perturbations to DOM cycling are expected with Arctic warming. The impact of photochemical and microbial degradation, and their interactive effects, on DOM composition and remineralization have been documented in Arctic soils and rivers. However, the role of microbes, sunlight and their interactions on Arctic DOM alteration and remineralization in the coastal ocean has not been considered, particularly during the spring freshet when DOM loads are high, photoexposure …

Neurophysiological Changes After Paired Brain And Spinal Cord Stimulation Coupled With Locomotor Training In Human Spinal Cord Injury, Timothy S. Pulverenti, Morad Zaaya, Monika Grabowski, Ewelina Grabowski Grabowski, Md. Anamul Islam, Jeffrey Li, Lynda M. Murray, Maria Knikou

Publications and Research

Neurophysiological changes that involve activity-dependent neuroplasticity mechanisms via repeated stimulation and locomotor training are not commonly employed in research even though combination of interventions is a common clinical practice. In this randomized clinical trial, we established neurophysiological changes when transcranial magnetic stimulation (TMS) of the motor cortex was paired with transcutaneous thoracolumbar spinal (transspinal) stimulation in human spinal cord injury (SCI) delivered during locomotor training. We hypothesized that TMS delivered before transspinal (TMS-transspinal) stimulation promotes functional reorganization of spinal networks during stepping. In this protocol, TMS-induced corticospinal volleys arrive at the spinal cord at a sufficient time to interact with …

Intangible Cultural Heritage: A Benefit To Climate-Displaced And Host Communities, Gül Aktürk, Martha B. Lerski

Publications and Research

Climate change is borderless, and its impacts are not shared equally by all communities. It causes an imbalance between people by creating a more desirable living environment for some societies while erasing settlements and shelters of some others. Due to floods, sea level rise, destructive storms, drought, and slow-onset factors such as salinization of water and soil, people lose their lands, homes, and natural resources. Catastrophic events force people to move voluntarily or involuntarily. The relocation of communities is a debatable climate adaptation measure which requires utmost care with human rights, ethics, and psychological well-being of individuals upon the issues …

Understanding Time, Cost, Quality, And Risk Trade-Off In Construction Projects Through A Review Of Literature & Survey Distribution, Aalaa Mohammed

Publications and Research

In the construction industry, projects consist of many different variables that affect successful completion. These variables may be scope, cost, time, quality, risk management and assessment, and more. Although all factors affect various construction projects differently, the three main variables that often result in a need for a trade-off decision are cost, quality, and time. Often referred to as the “Iron Triangle” or the “Triple Constraint”, many times owners and project managers are put under the pressure of having to choose two out of the three variables. If the project is cheap, it cannot be completed quickly and be of …

MODIS makes daytime and nighttime observations of the Earth’s thermal emission at a coarser spatial resolution (1000 m), while GOES-16, which has lower spatial resolution (2 km), measures the skin temperature at a much higher temporal resolution …

The Effects Of Late Spring Frost On Forest And Landscape Health And Recovery Of The Black Rock Forest, New York, Caroline Eco, Oliver Imhans, Aaron Davitt, Andrew B. Reinmann

Publications and Research

Projected changes in climate are expected to increase the frequency of late spring frost events in the Northeast US. Such events can be harmful to trees because freezing temperatures that occur after leaf-out can damage or kill young leaves. The resultant defoliation typically forces a second flush of leaves, but delays canopy development, which in turn delays the onset of canopy carbon uptake and alters canopy thermal properties. In this study, we analyzed a recent freeze event that occurred on 8-9 May 2020 (DOY 129-130) at Black Rock Forest (BRF), which is in the Hudson Highlands of southeastern New York …
