Soil thaw depth from permafrost in subarctic Canada
No full textThis datasets contains measures of soil thaw depth from permafrost in subarctic Canada. Soil thaw depth was measured in 2013 and 2014 in sites from Yukon and Northwest Territories.Estop-Aragones, C.; Fisher, J.P.; Cooper, M.A.; Thierry, A.; Treharne, R.; Murton, J.B.; Phoenix, G.K.; Charman, D.J.; Williams, M.; Hartley, I.P.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Soil dates using radiocarbon in profiles from permafrost in subarctic Canada
No full textThis dataset consists of soil dates determined using radiocarbon in profiles from permafrost in subarctic Canada. Depth-specific soil core samples were dated using radiocarbon. Soil cores were sampled during early summer in 2013 and 2014. Each year soil cores were sampled from a peatland plateau, thawing features of the peatland plateau, unburnt and burnt black spruce forests, and additional sites in Yukon and Northwest Territories.Estop-Aragones, C.; Fisher, J.P.; Cooper, M.A.; Thierry, A.; Treharne, R.; Murton, J.B.; Phoenix, G.K.; Charman, D.J.; Williams, M.; Hartley, I.P.

Soil moisture profiles from permafrost in subarctic Canada
No full textThis dataset consists of soil moisture profiles from permafrost in subarctic Canada. Soil mositure profiles were monitored during summer in 2013 and 2014 in Yukon and Northwest Territories. Monitored sites included peatland plateaus, unburnt and burnt black spruce forests, and additional sites.Estop-Aragones, C.; Fisher, J.P.; Cooper, M.A.; Thierry, A.; Treharne, R.; Murton, J.B.; Phoenix, G.K.; Charman, D.J.; Williams, M.; Hartley, I.P.

Soil dates using 210Pb in profiles from permafrost in subarctic Canada
No full textThis dataset consists of soils dated using lead-210 (210Pb) in profiles from permafrost in subarctic Canada. Soil cores were sampled during early summer in 2013 and 2014 from peatland plateaus, thawing peatland plateaus, burnt and unburnt black spruce forests in Yukon and Northwest Territories. The upper part of the soil profile was dated using 210Pb to quantify recent carbon accumulation rates.Estop-Aragones, C.; Fisher, J.P.; Cooper, M.A.; Thierry, A.; Treharne, R.; Murton, J.B.; Phoenix, G.K.; Charman, D.J.; Williams, M.; Hartley, I.P.

Extensive vegetation and soil surveys from multiple sites in boreal forests of subarctic Canada, 2013-2014
No full textThe dataset contains a stratified survey of ecological and soil states at sites where fine scale patterns of covariation between vegetation and edaphic characteristics were recorded. Key data collection included leaf area index, moss and organic matter thickness, surface and deeper soil moisture. Data were collected at sites in the Yukon (2013) and Northwest Territories (2014), Canada.Williams, M.; Estop-Aragones, C.; Fisher, J.P.; Murton, J.B.; Phoenix, G.K.; Hartley, I.P. (2020).

Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
