The C∗C^*-algebras of finitely aligned higher-rank graphs

We generalise the theory of Cuntz-Krieger families and graph algebras to the class of finitely aligned $k$-graphs. This class contains in particular all row-finite $k$-graphs. The Cuntz-Krieger relations for non-row-finite $k$-graphs look significantly different from the usual ones, and this substantially complicates the analysis of the graph algebra. We prove a gauge-invariant uniqueness theorem and a Cuntz-Krieger uniqueness theorem for the $C^*$-algebras of finitely aligned $k$-graphs.Comment: 27 page

Faith, Hope and Love: The Wartime Motivations of Lance Corporal Frederick Spratlin, MM and Bar, 3rd Battalion, CEF

In an attempt to understand the motivations that drive soldiers in war, historians often seek to capture the experience of an individual soldier through his letters, diaries and other personal accounts. But what of the artifacts that are left behind? The personal effects that arrive home to a family after a soldier’s death, neatly labeled and wrapped in yellowed paper. These also have a story to tell. Lance Corporal Spratlin, from Toronto, was killed during the Battle of Amiens in 1918. Today his remains lie in the Toronto Cemetery in France, but following his death one of his most treasured possessions was returned to his family—a small pocket-sized Bible. The condition of the Bible alone suggests something about the man who owned it. A gift from his daughter before he left for war, the Bible is worn, the leather is soft, the pages are so curled they stick together and the words New Testament are faded almost beyond recognition. To this day, 90 years after it was issued, the Bible is permanently bowed, an indication of its place in a soldier’s breast pocket. It is inside the back cover that we gain a clear insight into how a man endures the horrors of war. Penned in Spratlin’s clear, unmistakable handwriting are references to many biblical passages, 11 of them with a corresponding facet of war beside it

An observational study of the HIV/AIDS epidemic in Malta

An observational study was carried out comparing the HIV/ AIDS epidemic in Malta to that in South Glamorgan between 1984 and 1992. In both locations the important routes of transmission were use of contaminated blood products and unprotected sex. In both Malta and South Glamorgan 21 AIDS cases had died. The average time of survival from testing HIV positive and death in both locations was 28 months for those who had acquired the virus through blood products. However, for sexually acquired HIV, the average survival in Malta of 9 months contrasted with 33 months in South Glamorgan. Medical care was comparable so this fourfold difference in survival was likely to be due to later presentation of sexually acquired HIV cases in Malta. An HIV knowledge and behaviour survey of young Maltese in a local nightclub found that despite 90% of those questioned knowing that it was possible to contract HIV through unprotected sex, 36% of sexually active men questioned never used a condom.peer-reviewe

Joseph Welsh : A British Santanista (Mexico, 1832)

Joseph Welsh was the British Vice Consul in the port of Veracruz at the time of the uprising of 1832 by General Antonio Lopez de Santa Anna against the government of Anastasio Bustamante. Contravening the orders of his superiors, who reiterated the view that it was his obligation to observe the strictest neutrality in the conflict and not interfere in Mexican politics, Welsh found himself supporting Santa Anna and the rebels. As a result, at the end of March, Bustamante's administration demanded that he be removed from office. The British Minister Plenipotentiary, Richard Pakenham, acquiesced. This article provides a narrative of the events that led to Welsh's forced resignation and explores what they tell us about British diplomacy in Mexico during the early national period. It also analyses Welsh's understanding of the revolt and his views on Santa Anna, providing some insights, from a generally ignored British perspective,(1) into Santa Anna's notorious appeal and politico-military measures.Publisher PDFPeer reviewe
