Reframing the Chipped Edge: Combining Materiality, Ontology, and Embodiment to Rethink Stone Tool‐Making and Human Conscious Behavior in the Paleolithic Past

open access: yesAnthropology of Consciousness, EarlyView.
ABSTRACT Combining different theoretical frameworks can lead to new insights into the role of material things in shaping human experience in the Paleolithic period. This paper first presents a historical review of three theoretical approaches in archaeology, anthropology, and the philosophy of mind: Material culture and materiality studies, the ...

Cosmic Chronometers, Pantheon+ Supernovae, and Quasars Favor Coasting Cosmologies over the Flat ΛCDM Model

open access: yesThe Astrophysical Journal
We test and compare coasting cosmological models with curvature parameters $k=\left\{-1,0,+1\right\}$ in ${H}_{0}^{2}{c}^{-2}$ units and the flat ΛCDM model by fitting them to cosmic chronometers (CCs), the Pantheon+ sample of Type Ia supernovae (SNe ...

Observing the dark sector

open access: yes, 2019
Despite the observational success of the standard model of cosmology, present-day observations do not tightly constrain the nature of dark matter and dark energy and modifications to the theory of general relativity.

Understandings and critiques of biocultural diversity conservation and future recommendations for conservation actors

open access: yesConservation Biology, EarlyView.
Abstract As biocultural approaches to conservation gain traction (e.g., through international commitments to Indigenous Peoples and local communities) and external conservation actors increasingly seek to engage with on‐the‐ground holders of biocultural diversity, improved understanding is needed of what biocultural diversity means.

Effects of Type Ia Supernovae Absolute Magnitude Priors on the Hubble Constant Value

open access: yesThe Astrophysical Journal Letters
We systematically explore the influence of the prior of the peak absolute magnitude ( M ) of Type Ia supernovae (SNe Ia) on the measurement of the Hubble constant ( H _0 ) from SNe Ia observations.

Assembling Nutrition‐sensitive Agriculture: How Global Food Security Projects Are Sustained Despite Tensions, Contradictions and Failure

open access: yesDevelopment and Change, EarlyView.
ABSTRACT This article examines the global discourse surrounding nutrition‐sensitive agriculture (NSA) and its implementation within Feed the Future, a food security initiative of the US Agency for International Development in Guatemala. It explores how such global nutrition efforts have increasingly incorporated critiques advanced by critical nutrition

The Cosmological Constant

open access: yesLiving Reviews in Relativity, 2001
This is a review of the physics and cosmology of the cosmological constant. Focusing on recent developments, I present a pedagogical overview of cosmology in the presence of a cosmological constant, observational constraints on its magnitude, and the ...

Populating the Landscape: A Top Down Approach

open access: yes, 2006
We put forward a framework for cosmology that combines the string landscape with no boundary initial conditions. In this framework, amplitudes for alternative histories for the universe are calculated with final boundary conditions only.
