Arbitrary scalar-field and quintessence cosmological models [PDF]
, 2014 The mechanism of the initial inflationary scenario of the Universe and of its late-time acceleration can be described by assuming the existence of some gravitationally coupled scalar fields $$\phi $$, with the inflaton field generating inflation and the ...

When Thriving for More Collapses the System: The Academic Reproduction of Uncaring Structures
British Journal of Management, EarlyView.Abstract This essay argues that the widening gap between aspirational aims and visionary orientations and the prevailing practices in neoliberal academia stems from deeper, historically rooted, market‐based logics shaping our institutions, increasingly governed by economic values and academic subjectivities therein.

Use of Redshifts as Evidence of Dark Energy
PhysicsThe large-scale dynamics of the universe is generally described in terms of the time-dependent scale factor a(t). To make contact with observational data, the a(t) function needs to be related to the observable z(r) function, redshift versus distance ...

Traces of Extra Dimensions in Cosmology [PDF]
, 2010 In this thesis, we discuss the observational consequences of extra dimensions on cosmological phenomena. We begin with an overview of extra dimensions, from the initial ideas of Kaluza and Klein to the more recent concept of braneworld models and in ...

Singularity-free cosmological models
, 1996 Singularity-free cosmological models are a recent advance in the field of exact solutions. Previously thought not to exist, these models are globally hyperbolic and obey the strong energy condition everywhere.

Unmanagement Education for the Age of Climate Crisis
British Journal of Management, EarlyView.Abstract This paper examines how embodied, situated and relational experiences outside‐the‐classroom can open space for epistemic dislocations in Management Education under conditions of ecological crisis. Drawing on a qualitative pedagogical experience in a sustainability course in Brazil, informed by Design‐Based Research—whose assumptions of control,

Nonlinear theories and nonsingular cosmological models
, 1991 Bianchi I cosmological models describing the contraction of an anisotropic universe with an essentially nonlinear massless scalar field are considered.

Forecasts on the dark energy anisotropic stress for the esa euclid survey [PDF]
The cosmological constant Λ seems to be a not satisfactory explanation of the late-time accelerated expansion of the Universe, for which a number of experimental evidences exist; therefore, it has become necessary in the last years to consider ...

Journal of the Royal Anthropological Institute, EarlyView.Can a good death occur for those who balance on the edges of grievability? In Bali, where death marks a transition within the cycles of reincarnation, a good death depends on the mortuary care performed by intimate others – care that may be foreclosed to those whose lives are shaped by stigma.

Why cosmological data analysis of dark energy may inadvertently favor phantom energy models
Frontiers in Astronomy and Space SciencesMajor cosmological observation campaigns not only test the Λ cold dark matter (ΛCDM) model but also evaluate cosmological models beyond ΛCDM. To this end, they explore cosmological models that replace Λ with a dynamical model of dark energy (DDE ...
