Maytenus heterophylla N. Robson 1965
No full textCelastrus buxifolius Linnaeus, Species Plantarum 1: 197. 1753. "Habitat in Aethiopia." RCN: 1594. Lectotype (designated here by Robson): Herb. Clifford: 72, Celastrus 2, sheet A (BM-000558125). Current name: Maytenus heterophylla (Eckl. & Zeyh.) N. Robson (Celastraceae). Note: Sebsebe (in Symb. Bot. Upsal. 25(2): 88. 1985) indicated Clifford material as lectotype but did not distinguish between the two sheets there that are associated with this name. As they do not appear to be part of a single gathering, Art. 9.15 does not apply.Published as part of Jarvis, Charlie, 2007, Chapter 7: Linnaean Plant Names and their Types (part C), pp. 370-473 in Order out of Chaos.

Rashkova, T. The Robson cubics for matrix algebras with involution (Acta Univ. Apulensis Math. Inform.).
No full textLet R be the free associative algebra over a field K on
generators and let be the free
associative -algebra in one further indeterminate Consider
the set of polynomials in which are satisfied by
the matrix Such polynomials are
called laws over of the matrix Robson in [Robson, J.
C. Polynomials satisfied by matrices. J. Algebra 55 (1978), no.
2, 509--520; MR523471 (80j:15012)] proved that such laws are a
``consequence" of a finite set of laws and for he exhibited
generators called Robson cubics.
Here the author considers the special case when is a
symmetric or skew-symmetric matrix under the transpose
or symplectic involution and gives an explicit form of the Robson
cubics. Some other results are also given in case $n=3.

Off the Mark: Canada's 2008 Fiscal Accountability Ranking (also available in French)
No full textEvery year, legislators in Canada vote for budgets that set out targets for the coming fiscal year. But every year, governments tend to spend more than they promise at budget time. The result: accountability between legislators and voters breaks down. Canadians should demand better.fiscal policy, public accounts, Canadian federal, provincial and territorial governments fiscal accountability rankings
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
Garcinia gummi-gutta N. Robson 1968

Time and Money: The Challenge of Demographic Change and Government Finances in Canada
No full textAs a result of demographic change, Canadian governments face a net liability of $1.4 trillion for healthcare, education, seniors' and children's programs. Meeting this challenge will require fiscal discipline, partial prefunding and growth-friendly policies.fiscal policy, demographics
Benthoctopus profundorum Robson 1932
No full textBenthoctopus cf. profundorum Robson, 1932 Material examined: Benthoctopus cf. profundorum : * FMNH 307179, RV Atlantis HOV Alvin, 11°25'N 103°47'W (East Pacific Rise), Dive 3934, 15 November 2003, 2492 m, female, leg. & det. JR Voight. Diagnosis. Arms 3–4 times ML. Arm formula 1>2>3=4. Funnel organ W-shaped. Gills 6 lamellae per demibranch. Male characters unknown. Integument smooth. Remarks. This species shows some affinity with B. profundorum as described by Robson in his 1932 monograph. It has a similar W-shaped funnel organ, the same number of gill lamellae per demibranch (6–7 for the type of profundorum) and similarly sized suckers (SDI 5.9 reported for the type of profundorum versus 5.8 in our specimen). The arms appear to be very slightly shorter (83% of the total length in B. profundorum versus 78% in our specimen) and the web is slightly shallower (WDI 22.6% versus 34% in profundorum). Despite the similarities, we hesitate to place our specimen firmly in profundorum given the very great distance between the catch location and the type locality (34°37'N 140°32'E) of profundorum. Although other specimens have previously been attributed to profundorum, these need to be treated with caution. It is doubtful that any specimens other than the type can be referred to this species (Voss & Pearcy 1990).Published as part of Strugnell, Jan, Voight, Janet R., Collins, Patrick C. & Allcock, A.

AIDS and food insecurity: ‘New variant famine’ in Malawi?
No full textIn the midst of the 2002/3 food crisis in Southern Africa social scientists De Waal and Whiteside (well known for their respective work on the social construction of famines and the socio-economic impacts of AIDS in sub-Saharan Africa), hypothesised in the Lancet that the AIDS pandemic was triggering a ‘new variant famine’ across Southern Africa – a region characterised by recurrent severe food shortages and high adult HIV prevalence rates. This short review considers the applicability of the ‘new variant famine’ hypothesis to Malawi
Fiscal Tonic for an Aging Nation: A Shadow Federal Budget for 2007
No full textSaving and investment are critical to Canada's economy. They underpin today's prosperity and will be critical to raising living standards in the future. Growth in Canada's workforce is slowing, and a larger population of older Canadians will soon need pensions and social services. Federal fiscal policy must ensure that the environment in which Canadians work, save and invest encourages them to set aside resources for the future, and to invest in ways that will raise living standards for individual families, and for the country as a whole.fiscal policy, demographics
