This article contends that the relationship between the Reichswehrand the Republic was shaped by the primacy of foreign policybetween 1918 and 1923. In this period the major concern of theofficers was the stabilization of the German Reich, which wouldpreserve Germany as a Machtfaktor in Europe and serve as thebasis for a revisionist and militarized foreign policy. Foreignpolicy matters and aims shaped their attitude to domestic politics.Cooperation with the Republic enabled the officers to achievethe stabilization of the Reich by 1923. They were also ableto introduce important reforms in the military structure ofthe Reich, which showed that cooperation with the Republic couldpay dividends. In terms of the substance of foreign policy theReichswehr followed a pragmatic, unideological approach by developinglinks with the Red Army. By examining the relationship betweenthe Reichswehr and the Republic from the perspective of theprimacy of foreign policy, it is possible to come to a fullerunderstanding of the shifting nature of civil-military affairsin the Weimar Republic.  相似文献

Summary

Scholars of international relations generally invoke Hobbes as the quintessential theorist of international anarchy. David Armitage challenges this characterisation, arguing that Hobbes is regarded as a foundational figure in international relations theory in spite of as much as because of what he wrote on the subject. Thus, for Armitage, Hobbes is not the theorist of anarchy that he is made out to be. This article agrees with the general thrust of Armitage's critique while maintaining that it is still possible to imagine Hobbes as a theorist of anarchy. Hobbes is a theorist of anarchy, not in a political sense, but in a metaphysical sense. This conception of anarchy is a reflection of a comprehensive theological account of reality that is grounded in an omnipotent God. Any historical inquiry into the foundations of modern international thought must take account of theology, because theology defines the ultimate coordinates of reality in terms of which the concepts of international thought are intelligible.  相似文献

This paper documents court‐imposed bail and sentencing conditions with spatial dimensions, such as red zones, no contact conditions, curfews and prohibitions to demonstrate, issued in the context of criminal proceedings. These conditional orders, which are growing in importance and have a significant impact on the lives of marginalized groups of people, have not received the attention they deserve in the literature. As opposed to better publicized forms of spatial regulation such as legislation or policing strategies, these conditional orders are a distinctive form of spatial tactic that rely on ancient and routinized rules of criminal procedure and the practices of the courts. In order to understand this spatial tactic, and its impact on marginalized people's rights and uses of spaces, we argue that it is necessary to pay attention to the legal rationalities, knowledge and practices that sustain them.  相似文献

The liberalisation of the White Australia policy in the mid-1960s was a seminal event in Australian history. It marked the beginning of the end for the racial conception of society which had defined the federation since the late-nineteenth century. Cabinet’s discussions of the proposed changes during these years demonstrate that most Australian political leaders were not only fundamentally opposed to reform but also unconvinced by arguments emphasising the policy’s administrative inconsistencies, lack of humanitarianism and racially discriminatory features. Nor were they entirely swayed by arguments of diplomatic expediency, which had been advanced by senior Immigration and External Affairs officials since the 1950s. The decline of British race patriotism in the early 1960s weakened the ideological foundations of White Australia and allowed policy-makers to reconsider its foreign policy implications, especially in terms of Australia’s relations with Asia. Although cautious, the reforms of the mid-1960s represented an important break with the policy’s fundamental principles and provided the groundwork for further liberalisation and the formal abolition of White Australia in the 1970s.  相似文献

Stable carbon (δ13C) and nitrogen (δ15N) isotope ratios are commonly used to reconstruct palaeodiets and palaeoenvironments. The method is based on our knowledge of isotopic patterns in plants, which are subject to taxonomic and environmental variability. While previous researchers have addressed isotopic variability amongst plants, no studies have looked extensively at a broad suite of taxa over multiple temporal scales from within the savanna biome so as to provide baseline data for palaeodietary and palaeoenvironmental studies. Here we document variations in the isotopic compositions of plants collected over two years from the Kruger National Park, South Africa, with respect to species and anatomical differences, and the influences of geological substrate and spatio-temporal shifts in climate. Results show that environmentally-induced carbon isotopic variations in plants within this region are generally smaller than 2‰, which is lower than what has been previously reported for plants compared across multiple habitat-types. These data suggest that δ13C differences of 2‰ or more (or 1‰ if the diet is predominantly C4) between animals from a given area reliably indicate real dietary differences. Plant δ15N values vary greatly between different microhabitats (by up to 4‰), responding to a range of environmental influences that may, in turn, significantly influence variation in animal δ15N values.  相似文献

This article examines the introduction of blood transfusion into general practice from the end of the First World War to the Second World War. Developments during most of this period were not the result of new discoveries but rather the spread of ideas and the establishment of donor organizations to secure an adequate blood supply. The identification, testing, and organization of potential donors were done in a wide variety of settings that reflected differences in political and cultural experiences. At the end of the 1930s, with war approaching, the resolution of problems with storage of blood and the discovery of new techniques for separating and storing plasma dramatically changed transfusion practice. Thus, the innovations of the Second World War were very much based on the development of broad donor organizations plus the new technical discoveries that had occurred during the interwar period.  相似文献
