An Ecological Study of Timberline and Alpine Areas, Mount Lincoln, Park County, Colorado
During the short alpine growing season of 1945 the authors had the opportunity of studying conditions and biota on Mount Lincoln, Park County, Colorado, in an attempt to evaluate the ecological conditions and animal communities of the area. Of the large amount of taxonomic and ecological zoology published on the state, most has been in the field of autecology, and, except in the province of aquatic studies, little has appeared bearing on synecological relations, especially among invertebrates. The marked differences between the physiography, climatology, and biology of timberline, alpine, and other stations seemed to offer a field well worthy of investigation. Since the work was done, other factors have been introduced which have greatly altered the nearly primitive conditions encountered at the time of the investigation. One of the areas has been entirely destroyed by the formation of a water storage lake, and others have been affected through heavy summer grazing by bands of sheep.
The material published on the Mount Lincoln area is very limited. Cary (1911) was concerned with similar areas in other parts of the state, but apparently he did not work around the mountains at the head of the South Platte. The most detailed paper on the region is that of Patton and his collaborators (1912) which covers the physiography very completely. There are scattered references to the animal life of the vicinity in Coues (1874), Sclater (1912), Warren (1942), and elsewhere. The most complete published reports on the animal life of the region are those of Brewer (1871) and Allen (1872, 1876a, 1876b); the first of Allen\u27s papers is the source of most of Coues\u27 references to the Mount Lincoln avifauna. None of these papers deals with the invertebrates, save for comments by Brewer on the relative abundance of certain orders of insects
The birth of a politician: Harold Wilson and the bonfires of controls, 1948-9
This article uses a detailed examination on the 1948 and 1949 Bonfires of Controls to reassess Harold Wilson's development as a politician and examine the broader relationship between popular politics and economic policy. Whilst acknowledging the continued importance of the latter within Wilson's self-identification as a modernizing 'specialist', it contends that these events are best viewed as representing the birth of a professional politician. It will show that, although economically motivated, there was a marked disparity between each Bonfire's illusion and reality. Far from being entirely rational, each announcement straddled the gap between politics and economics. Within a post-war political landscape that had seen debates about controls become increasingly emotive, Wilson used the Bonfires to seize advantage. As a result, they can be seen to signify the point of his development from a self-identified professional economist to an astute political actor. © The Author [2013].

Proposed shunt rounding technique for large-scale security constrained loss minimization
The official published version can be obtained from the link below - Copyright @ 2010 IEEE.Optimal reactive power flow applications often model large numbers of discrete shunt devices as continuous variables, which are rounded to their nearest discrete value at the final iteration. This can degrade optimality. This paper presents novel methods based on probabilistic and adaptive threshold approaches that can extend existing security constrained optimal reactive power flow methods to effectively solve large-scale network problems involving discrete shunt devices. Loss reduction solutions from the proposed techniques were compared to solutions from the mixed integer nonlinear mathematical programming algorithm (MINLP) using modified IEEE standard networks up to 118 buses. The proposed techniques were also applied to practical large-scale network models of Great Britain. The results show that the proposed techniques can achieve improved loss minimization solutions when compared to the standard rounding method.This work was supported in part by the National Grid and in part by the EPSRC.

Matching the High Momentum Modes in a Truncated Determinant Algorithm
Within a truncated determinant algorithm, two alternatives are discussed for
including systematically the remaining ultraviolet modes. Evidence is presented
that these modes are accurately described by an effective action involving only
small Wilson loops.Comment: LATTICE98(algorithms) ; typos correcte
âLabour History and its political role â a new landscapeâ
As I was thinking about what to say today I read an article on Manning Clark and found something that made me pause. It was a description of our venerable journal, Labour History, but characterizing it in terms that none of us would use, at least not in public. Instead of describing our field, our sources or our methods, our long list of illustrious contributors, it said that Labour History was the journal of Australiaâs left-wing historians.
Well, this was in Wikipedia â but nonetheless it struck me that, yes, this is a truth I am prepared to accept. Iâm sure there others here today â editors, contributors, readers - who share my acceptance. While I was editor of the journal I assumed it was part of a cluster of left-wing journals, and of course its founding editors were quite clear about its left-wing purpose. And yet, in academic gatherings today labour historians rarely talk about themselves as left-wing.
To use a very tired metaphor, left-wing politics is our elephant in the room. If that is so, perhaps with a bit of imagination we might get our gear together and move into a new landscape
Service Learning and Curriculum Transfusion
Newcomers to service learning, caught up by its initial successes, are frequently not aware that service learning is capable, with appropriate long-term structuring, of exhibiting developmental stages that feed into patterns of academic growth
