Polarizing trajectories of colonial ideologies: A latent class growth analysis of historical negation and symbolic exclusion. [PDF]

Br J Soc Psychol
Abstract The impassioned advocacy both for and against Indigenous rights in recent years suggests a polarization of public opinion. Accordingly, we theorize increasingly divided endorsement of two ideologies that challenge Indigenous rights to material and symbolic equality—historical negation and symbolic exclusion, respectively (the ‘Dark Duo ...

Menopause Averted a Midlife Energetic Crisis With Help From Older Dependent Children and Parents: A Simulation Study. [PDF]

Am J Biol Anthropol
ABSTRACT Objectives The grandmother hypothesis proposes that ancestral women ceased reproduction midlife to instead provision their grandchildren. An alternative “two‐sex” account proposes that the high energetic burden of caring for slow‐developing offspring was met with biparental investment.

Comparative Binding Studies of the Chelators Methylolanthanin and Rhodopetrobactin B to Lanthanides and Ferric Iron. [PDF]

Chembiochem
The synthesis and the investigation of the lanthanide (Ln) and Fe‐binding properties of the putative lanthanophore methylolanthanin (MLL) and the siderophore rhodopetrobactin B (RPB B) are reported. While both chelators bind Lns, they unexpectedly precipitate with Lns under biologically relevant conditions and thereby challenge the proposed classic ...

Estimating fertility using adults: A method for under‐enumerated pre‐adult skeletal samples

American Journal of Biological Anthropology, Volume 181, Issue 2, Page 262-270, June 2023., 2023
Abstract Objectives Infant underrepresentation poses a great risk to accurate palaeodemographic findings when analyzing skeletal samples. Empirically derived palaeodemographic methods all require unbiased or minimally biased pre‐adult representation for estimating demographic characteristics, including fertility.

A low‐complexity transmit combining method for downlink of massive multiuser multiple input multiple output systems

Electronics Letters, Volume 59, Issue 10, May 2023., 2023
In this paper, a low‐complexity transmit combining scheme for the massive MU‐MIMO systems with time division duplex si proposed, devised in a similar manner as the well‐known Tomlinson‐Harashima precoding (THP) scheme. In order to suppress multiuser interference with a lower computational complexity we here employ the Gram‐Schmidt orthogonalization ...

Attenuation of Piwil2 induced by hypoxic postconditioning prevents cerebral ischemic injury by inhibiting CREB2 promoter methylation

Brain Pathology, Volume 33, Issue 1, January 2023., 2023
Schematic depicting mechanism by which HPC protects neurons against tGCI in CA1 through Piwil2‐mediated epigenetics. Abstract Epigenetic modification contributes to the pathogenesis of cerebral ischemia. Piwil2 belongs to the PIWI proteins subfamily and has a key role in the regulation of gene transcription through epigenetics.

Upper Troposphere Smoke Injection From Large Areal Fires

Journal of Geophysical Research: Atmospheres, Volume 126, Issue 23, 16 December 2021., 2021
Abstract Large areal fires, such as those ignited following a nuclear detonation, can inject smoke into the upper troposphere and lower stratosphere. Detailed fire simulations allow for assessment of how local weather interacts with these fires and affects smoke lofting.

Vision Mātauranga research directions: opportunities for iwi and hapū management plans

Kōtuitui: New Zealand Journal of Social Sciences Online, Volume 16, Issue 2, Page 371-383, November 2021., 2021
ABSTRACT The Ministry of Business, Innovation and Employment (MBIE) Vision Mātauranga policy has created a clear message for researchers in Aotearoa/New Zealand – that research conducted in Aotearoa New Zealand should recognise and support the ‘unlocking of the innovative potential of Māori for the benefit of all New Zealand’ and be designed with a ...

The obstetrical dilemma hypothesis: there's life in the old dog yet

Biological Reviews, Volume 96, Issue 5, Page 2031-2057, October 2021., 2021
ABSTRACT The term ‘obstetrical dilemma’ was coined by Washburn in 1960 to describe the trade‐off between selection for a larger birth canal, permitting successful passage of a big‐brained human neonate, and the smaller pelvic dimensions required for bipedal locomotion. His suggested solution to these antagonistic pressures was to give birth prematurely,

Are fathers a good substitute for mothers? Paternal care and growth rates in Shodagor children

Developmental Psychobiology, Volume 63, Issue 6, September 2021., 2021
Abstract Biparental care is a hallmark of human social organization, though paternal investment varies between and within societies. The facultative nature of paternal care in humans suggests males should invest when their care improves child survival and/or quality, though testing this prediction can be challenging because of the difficulties of ...
