The Savannah Hypothesis of Shopping [PDF]

open access: yesBusiness Strategy Review, 2005
Predicting human behaviour is a complex process dependent in part on instinctive, physiological, rational and emotional considerations. Arguably, all of these are just chemistry – think of the adrenalin fight or flight reflex. But why does brain chemistry affect our actions?

What shapes fire size and spread in African savannahs?

open access: yesRemote Sensing in Ecology and Conservation, 2021
Fires play an important role in savannah ecosystems, shaping among other things vegetation structure and altering species composition. As direct and indirect anthropogenic pressures on these ecosystems increase, fire dynamics in savannahs are expected to

The Limpopo–Mpumalanga–Eswatini Escarpment—Extra-Ordinary Endemic Plant Richness and Extinction Risk in a Summer Rainfall Montane Region of Southern Africa

open access: yesFrontiers in Ecology and Evolution, 2022
Climatic, edaphic, and topographic differences between mountains and surrounding lowlands result in mountains acting as terrestrial islands with high levels of endemic biota.

Effects of NDURE on Timely Adjuvant Radiotherapy in HNSCC: Subgroup Analysis of an RCT. [PDF]

open access: yesLaryngoscope
In this subgroup analysis of a randomized clinical trial of 145 patients with locally advanced head and neck squamous cell carcinoma, the enhanced navigation‐based intervention NDURE improved initiation of timely postoperative radiation therapy (PORT) relative to usual care across nearly all demographic and clinical subgroups, including patients with ...

Abel-type weighted means transformations into ℓ

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
Let qk=(k+α    k) for α>−1 and Qn=∑k=0nqk. Suppose Aq={ank}, where ank=qk/Qn for 0≤k≤n and 0 otherwise. Aq is called the Abel-type weighted mean matrix. The purpose of this paper is to study these transformations as mappings into ℓ.

The Abel-type transformations into Gw

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
The Abel-type matrix Aα,t was introduced and studied as a mapping into ℓ by Lemma (1999). The purpose of this paper is to study these transformations as mappings into Gw. The necessary and sufficient conditions for Aα,t to be Gw-Gw are established.

Repeatability of fruit traits from two Hancornia speciosa populations from the core region of the Brazilian Cerrado [PDF]

open access: yesPesquisa Agropecuária Brasileira, 2018
: The objective of this work was to estimate the repeatability coefficients of mangaba (Hancornia speciosa) fruit traits, in order to define the number of fruit needed for an accurate selection of superior genotypes, as well as to conjecture about the ...

Evidence for Involvement of ADP-Ribosylation Factor 6 in Intracellular Trafficking and Release of Murine Leukemia Virus Gag

open access: yesCells
Murine leukemia viruses (MuLVs) are simple retroviruses that cause several diseases in mice. Retroviruses encode three basic genes: gag, pol, and env.
