Above- and below-ground competition in high and low irradiance: tree seedling responses to a competing liana Byttneria grandifolia
No full textAbstract: In tropical forests, trees compete not only with other trees, but also with lianas, which may limit tree growth and regeneration. Liana effects may depend on the availability of above- and below-ground resources and differ between tree species. We conducted a shade house experiment to test the effect of light (4% and 35% full sun, using neutral-density screen) on the competitive interactions between seedlings of one liana (Byttneria grandifolia) and three tree species (two shade-tolerant trees, Litsea dilleniifolia and Pometia tomentosa, and one light-demanding tree, Bauhinia variegata) and to evaluate the contribution of both above- and below-ground competition. Trees were grown in four competition treatments with the liana: no competition, root competition, shoot competition and root and shoot competition. Light strongly affected leaf photosynthetic capacity (light-saturated photosynthetic rate, Pn), growth and most morphological traits of the tree species. Liana-induced competition resulted in reduced Pn, total leaf areas and relative growth rates (RGR) of the three tree species. The relative importance of above- and below-ground competition differed between the two light levels. In low light, RGR of the three tree species was reduced more strongly by shoot competition (23.1¿28.7% reduction) than by root competition (5.3¿26.4%). In high light, in contrast, root competition rather than shoot competition greatly reduced RGR. Liana competition affected most morphological traits (except for specific leaf area and leaf area ratio of Litsea and Pometia), and differentially altered patterns of biomass allocation in the tree seedlings. These findings suggest that competition from liana seedlings can greatly suppress growth in tree seedlings of both light-demanding and shade-tolerant species and those effects differ with competition type (below- and above-ground) and with irradianc
Which Canadian Seniors Are Below the Low-Income Measure?
No full textAbout 6% of seniors in Canada have family incomes below the Low-Income Measure. (The Low-Income Measure is 50% of the median family income, adjusted for family size, and is a commonly used, if arbitrary, operational definition of relative poverty.) This is a low rate by international standards, in sharp contrast to the high rate in Canada about 35 years ago. It is lower than the comparable rates for the general Canadian population or for families with children and more Canadians leave below-LIM status during their retirement years than enter it. Canadian income tax data show that the remaining 6% are disproportionately immigrant, female, currently unmarried and supporting dependent children (possibly grandchildren). Age does not appear to be of great importance.relative poverty, Canadian income distribution, pension adequacy
Variations on the Author
No full text“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

Utilizing Geothermal Resources Below 150 C (300 F)
No full textExcept for the steam-dominated geothermal field at Geysers, Calif., the use of geothermal energy in the US has been minimal. We have been so preoccupied with searching for the high temperature resources (above 350 F), for generating electricity, that we have largely ignored the greatest potential for geothermal energy, that at temperatures below 150 C (300 F). These waters are much more abundant than the higher temperature ones, and, therefore, represent 10 or more times as much useable energy than the total of the energy in all the high temperature waters. The problems have, in part, been technological—how to economically convert these lower temperature geothermal waters to useful energy—and in part institutional. This paper describes the last five year’s program, largely centered at the Idaho National Engineering Laboratory, to make it more practical and economical to harness the lower temperature geothermal resources.</jats:p

Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
