    This work is organized into a general introduction, four chapters of experimental contributions and general conclusions. Chapter 1 contains the general introduction, aiming to provide a synopsis about genetic application in animal science. Two main topics were debated in this thesis, modern genomic tools applied in animal breeding and animal biodiversity. The first two experimental contributions (Chapters 2 and 3) concerned animal breeding programs, particularly the first and the last step: variance components and breeding values estimation, respectively. The contribution about variance components estimation was the result of my abroad period at the University of Georgia (USA). Chapter 3 deals with the estimation of heritability and genomic breeding values for milk fatty acid profile. Regarding the animal biodiversity, two researches were carried out analyzing both cattle and sheep breeds farmed in Italy. Several statistical approaches were used to identify selection signatures in livestock. Chapter 4 analyzed genetic diversity among five cattle breeds: two purebreds and three crossbreeds raised in Sardinia. In the Chapter 5, in order to highlight genome regions that can differentiate livestock production, selection signatures were investigated among different productive aptitudes in the Italian ovine stock. Finally, the general conclusions reported in Chapter 6 offered a short overview of the main results obtained during the PhD

    Anarchism and the British warfare state : The prosecution of the War Commentary Anarchists, 1945

    Get PDF
    The arrest and prosecution in 1945 of a small group of London anarchists associated with the radical anti-militarist and anti-war publicationWar Commentary at first appears to be a surprising and anomalous set of events, given that this group was hitherto considered to be too marginal and lacking in influence to raise official concern. This article argues that in the closing months of World War II the British government decided to suppress War Commentary because officials feared that its polemic might foment political turmoil and thwart postwar policy agendas as military personnel began to demobilize and reassert their civilian identities. For a short period of time, in an international context of “demobilization crisis”, anarchist anti-militarist polemic became a focus of both state fears of unrest and a public sphere fearing ongoing military regulation of public affairs. Analysing the positions taken by the anarchists and government in the course of the events leading to the prosecution of the editors of War Commentary, the article will draw on “warfarestate” revisions to the traditional “welfare-state” historiography of the period for a more comprehensive view of the context of these events
