Ecological and Developmental Perspectives on Social Learning : Introduction to the Special Issue.

Hum Nat 2021 Apr 20. Epub 2021 Apr 20.

Department of Anthropology, University of Oregon, Eugene, OR, USA.

In this special issue of Human Nature we explore the possible adaptive links between teaching and learning during childhood, and we aim to expand the dialogue on the ways in which the social sciences, and in particular current anthropological research, may better inform our shifting understanding of how these processes vary in different social and ecological environments. Despite the cross-disciplinary trend toward incorporating more behavioral and cognitive data outside of postindustrial state societies, much of the published cross-cultural data is presented as stand-alone population-level studies, making it challenging to extrapolate trends or incorporate both ecological and developmental perspectives. Here, contributors explore how human life history, ecological experience, cumulative culture, and ethnolinguistics impact social learning and child development in foraging and transitioning societies around the world.

Discrete-Time Markov Chain Modelling of the Ontario Air Quality Health Index.

Water Air Soil Pollut 2021 15;232(4):158. Epub 2021 Apr 15.

Department of Civil Engineering, McMaster University, Hamilton, ON L8S 4L7 Canada.

The Air Quality Health Index (AQHI) is an aggregate indicator of air pollution used to communicate to Canadians the health impact of short-term exposure to current air pollutant levels. Understanding the stochastic behaviour of the AQHI can aid public health officials in predicting air pollution levels, determining the likelihood and duration of air quality advisories, and planning for increased strain on the health care system during periods of higher air pollution. Previous research has applied discrete-time Markov chains to investigate stochastic behaviour of air pollution indices but only in a handful of regions and none with the same climatic characteristics as Canadian regions.

Authors:
J C Ritchie

New Phytol 1995 Aug;130(4):469-494

Department of Botany, University of Toronto and Institute of Earth Studies, University of Wales, Aberystwyth.

Long-term plant community dynamics has been investigated by analyses of macro- and microfossil remains found in unconsolidated limnic and terrestrial sediments, chiefly of Late-Quaternary and Recent age. Plant macrofossils preserved in packrat (Neotoma) midden sites in semi-arid regions have yielded the most informative data for the period between the lastest glacial to the present day. The remains can, with few exceptions, be identified to species level, they represent a large (>75%) proportion of the species composition of vegetation within a radius of 30-50 m of a site, and they can be dated by the accelerator mass-spectrometric radiocarbon method.
