A unified proof of Brooks' theorem and Catlin's theorem
We give a new proof of Brooks' theorem that immediately implies a
strengthening of Brooks' theorem, known as Catlin's theorem.Comment: Proof rewritten based on referee's repor
Distribution and ecology of the stoneflies (Plecoptera) of Flanders (Belgium)
Based on a literature survey and the identification of all available collection material from Flanders, a checklist is presented, distribution maps are plotted and the relationship between the occurrence of the different species and water characteristics is analysed. Of the sixteen stonefly species that have been recorded, three are now extinct in Flanders (Isogenus nubecida, Taeniopteryx nebulosa and T. schoenemundi), while the remaining species are rare. The occurence of stoneflies is almost restricted to small brooks, while observations in larger watercourses are almost lacking. Although a few records may indicate that some larger watercourses have recently been recolonised, these observations consisted of single specimens and might be due to drift. Most stonefly population are strongly isolated and therefore extremely vulnerable. Small brooks in the Campine region (northeast Flanders), which are characterised by a lower pH and a lower conductivity, contained a different stonefly community than the small brooks in the rest of Flanders. Leuctra pseudosignifera, Nemoura marginata and Protonemura intricata are mainly found in small brooks in the loamy region, Amphinemura staandfussi, Isoperla grammatica, Leuctra fusca, L.hippopus, N. avicularis and P. meyeri mainly occur in small Campine brooks, while L. nigra, N. cinerea and Nemurella pictetii can be found in both types. Nemoura dubitans can typically be found in stagnant water fed with freatic water. Sustainable populations of these stonefly species can only be achieved when their present habitats are adequately protected and in addition, measures should be taken to connect and enlarge the remaining populations

If War Is Everywhere, Then Must the Law Be Nowhere?
This response focuses on one of the most difficult questions posed by Rosa Brooks\u27s How Everything Became War and the Military Became Everything: How should the erosion of the war / peace dichotomy impact the justifications for the use of lethal force by the United States government and what, if any, role is there for law in this context? While Brooks is unambiguously critical of Bush administration legal policies that asserted expansive executive war powers, she is less certain about the Obama administration\u27s own reliance on the war paradigm to justify its targeted killing policies. While describing these policies as “undermining the international rule of law,” Brooks declines to take a firm stance on whether they are lawful or unlawful, and she rejects the views of critics who would “jam war back into its old box.” It is a credit to Brooks that she is willing to acknowledge such ambivalence, but her approach comes at a cost. It is difficult to maintain a critical stance on governmental policy while simultaneously undermining the very legal foundations that most plausibly support that stance. In this way, critique quickly turns into apology
Finally Speaking Up: Sexual Assault in the Civil War Era
Trigger warning: This article contains detail concerning rape and sexual assault.
On March 12, 1864, in the midst of a bloody war which had long overflowed its thimble, Margaret Brooks was returning from her home near Memphis, Tennessee when her wagon broke down in Nonconnah Creek. Not long after her driver left to find help, three rambunctious New Jersey cavalrymen, all white, approached Brooks, demanding her money. She was then raped multiple times at gunpoint [excerpt]
Continuing the Discussion of the Spiroans and Their Entrepots: A Reply to Brooks\u27s Critique of My New Paradigm/or the Archeology of the Arkansas Valley
Although Brooks seems to agree with me that the archeology of the Arkansas Valley requires a new paradigm, he clearly believes that mine -- which he apparently considers a poorly founded Binfordian screed written primarily for its shock value -- is not the one. Where, according to Brooks, have I gone wrong in my work on the archeology of the Arkansas Valley? Which of my generalizations does he consider so poorly grounded empirically as to suggest, as he insinuates, professionally and perhaps even ethically questionable work, and in what ways does he consider them deficient
Leonard Brooks—War Artist (1911–2011)
Just 13 days after his 100th birthday, Leonard Brooks, a Second World War Canadian artist passed away. Trained as a commercial artist, Brooks joined the Royal Canadian Navy (RCN) in 1943 and was appointed an official war artist the following year. He painted scenes of the Royal Canadian Navy on Canada’s east coast, shipboard life on minesweepers, frigates and aircraft carriers and various war scenes in England and France. A total of 113 pieces of his work, “all my children” in his words, are held by the Canadian War Museum
