The Road to the Cobourg Court Room: New Material from the Archives of the Canadian War Museum on the Sir Arthur Currie-Sir Sam Hughes Dispute, 1918-1919

The post-First World War dispute between Sir Sam Hughes, Minister of Militia and Defence from October 1911 to November 1916 and Sir Arthur Currie, General Officer Commanding the Canadian Corps from 9 June 1917 to the end of the war, must be one of the least dignified episodes in Canadian military history. Hughes, although very energetic, was erratic and arbitrary and was fired by Prime Minister Sir Robert Borden for his inefficient administration of the Canadian military forces overseas. Currie, on the other hand, led the Canadian Corps in a stunning series of successes: Hill 70, Passchendaele, Amiens, the Drocourt-Queant Line, the Canal du Nord, and the final entry into the Belgian town of Mons on the last day of the war. He has, indeed, been viewed by historians as one of the war’s most capable field commanders and, arguably, as Canada’s greatest native-born military commander

An overview of the Lejeuneaceae in Australia

As currently understood, the Lejeuneaceae flora of Australia consists of 122 species in 27 genera. The family occurs almost exclusively in rainforested areas along the eastern coast of the continent. Based on species composition, three floristic regions are recognized: tropical, subtropical and temperate. The tropical region contains 80 percent of the total number of Lejeuneaceae found in Australia, the subtropical region contains 45 percent, and the temperate region only 15 percent of the total flora. The affinities of the Lejeuneaceae in the tropical and subtropical regions are strongest with the Asian flora, and those of the temperate region are strongest with the New Zealand flora. The diversity of the Lejeuneaceae flora in Australia is higher than might be expected for a non-equatorial region. This diversity may result from the wide variety of rainforest habitats that are available along both latitudinal and altitudinal gradients. The temperate flora is probably derived from that which existed in Australia, New Zealand, Antarctica and probably southern South America prior to the breakup of Gondwanaland. The modern tropical flora is probably a mixture of species that were part of the original northern Gondwanan flora and those that have invaded more recently

Evaluating Strategies for Promoting Minority Construction Contracting

This analysis addresses the issue of disparity between minority-owned businesses and non minority-owned businesses in securing city contracts in the city of Grand Rapids, Michigan. Understanding the implications of unfair contract disbursement on the economy of Grand Rapids is extremely important as the city becomes more diverse. It is important that Grand Rapids remain a viable city and to do so, fairness in contract disbursement must be addressed. It examines the previous policy which required businesses to maintain a percentage of minority workers, the policy used by the city of Chicago which sets aside a certain portion of city contracts for minority owned businesses, and the current policy which uses a discount program to help achieve diversity in awarding contracts. This analysis examines each policy on five criteria: 1) Does the program increase access to government contracts? 2) What is the percentage increase of minority and women businesses in city contracts? 3) Can the policy stand up in the courts? 4) What is the cost to the city? 5) Is the policy politically feasible

A Family of Indecomposable Positive Linear Maps based on Entangled Quantum States

We introduce a new family of indecomposable positive linear maps based on entangled quantum states. Central to our construction is the notion of an unextendible product basis. The construction lets us create indecomposable positive linear maps in matrix algebras of arbitrary high dimension.Comment: 16 pages LaTex: updated and a derivation of a lower bound on epsilon is added and calculated for one of the examples.

A re-evaluation of Cheilolejeunea subgenus Xenolejeunea

Cheilolejeunea subgenus Xenolejeunea Kachroo & Schust. is emended to account for variability observed in stem anatomy and lobule structure. Cheilolejeunea subgenus Tegulilejeunea Schust. is reduced to synonymy with subgenus Xenolejeunea. A new sectional classification of subgenus Xenolejeunea is proposed (sections Gigantae, Meyenianae, and Xenolejeunea). A key distinguishes among the sections and the 10 species accepted in the subgenus, which is known from Australasia, Oceania and tropical Asia. A nomenclator and discussion is provided for each species. Comments on excluded species conclude the treatment

Effect of Tilt Sensor versus Heel Loading on Neuroprosthesis Stimulation Reliability and Timing for Individuals Post-Stroke during Level and Non- Level Treadmill Walking

Study background: Non-level walking may adversely affect stimulation of neuroprostheses as initial programming is performed during level walking. The objectives of this study were to assess stimulation reliability of tilt and heel sensor-based neuroprosthesis stimulation during level and non-level walking, examine stimulation initiation and termination timing during level and non-level walking, and determine whether heel or tilt sensor-based stimulation control is more robust for non-level ambulation. Methods: Eight post-stroke individuals with drop foot who were able to actively ambulate within the community were selected for participation. Each subject acclimated to the neuroprosthesis and walked on a treadmill randomly positioned in inclined, level and declined orientations. The primary measures of interest were stimulation reliability and timing. Results: Statistically significant differences in tilt, but not heel, sensor-based stimulation reliability were observed between level and non-level walking trials. Tilt sensor-based stimulation initiation occurred significantly closer to swing as the treadmill processed from declined to inclined orientations. No statistically significant differences in stimulation reliability or timing were observed between theoretical heel versus clinical tilt sensor-based stimulation control. Discussion and conclusions: Tilt sensor-based stimulation reliability may be adversely affected by non-level walking. Differences in stimulation initiation timing with tilt sensor-based control during non-level walking may be advantageous as stimulation initiation closer to swing during inclined ambulation may allow for greater ankle plantar flexion to assist with forward progression. Despite a lack of significant differences in stimulation reliability or timing between sensors, theoretical heel sensor-based stimulation control exhibited more consistent stimulation timing with less variability than for tilt sensor-based stimulation during non-level ambulation
