When, on 6 April 1917, the United States entered into the First World War, a wave of anti-German sentiment captured the nation. The Army was not immune from accusations of subversion. In 1917 Senator Miles Poindexter accused a high ranking officer named Carl Reichmann of being in league with Germany. Despite the support from officers such as Hugh Lennox Scott and John J. Pershing, Reichmann was not permitted a promotion to general or service in France. Although most senators supported the promotion, Poindexter was able to prevent a vote on the subject using internal Senate rules. The resulting notoriety Poindexter gained made him a viable Republican candidate in the 1920 election. Although the military did not prevail over Poindexter — thereby continuing the constitutional expectation of military subservience to the civil government — the forces sent to France were without a commander who had gained a scholarly understanding of modern warfare well before the actual conflict.  相似文献

Past scholarship has offered varying explanations for why presidents choose to use executive orders. However, to this point, much of what we know of unilateral powers does not adequately address the role the bureaucracy plays in the president's decision. This research seeks to account for bureaucratic factors as a strategic presidential consideration in the employment of such directives. I classify executive orders from 1989–2012 based on which agency or agencies they apply to, and consider the importance of various characteristics (e.g. agency ideology, level of centralization, politicization, etc.) in determining which organs of the bureaucracy presidents will direct executive orders to generally. The results provide evidence that the White House directs fewer executive orders to agencies that have a politically independent leadership structure, and this result holds across a variety of measures judging an order's impact. The results demonstrate that the type of directive is crucial in determining a president's strategic decision to use executive orders, in line with previous research, and that agency centralization is one crucial component of this strategic calculation.  相似文献

Although Schmitt’s enthusiastic conversion to National Socialism is well known, his short history of the German Kaiserreich, published in 1934, remains neglected in Anglophone scholarship. This article contextualizes Schmitt’s narrative through the National Socialist conception of history and its accompanying teleology leading to the formation of the Third Reich. By placing Schmitt’s historical text in conversation with his earlier Staat, Bewegung, Volk, this article argues that Schmitt appropriated the history of the Kaiserreich to construct liberalism as a social pathology which could only be cured through the ‘concrete state theory’ he outlined in Staat, Bewegung, Volk. Furthermore, this article argues that Schmitt’s history relied heavily on propagandistic clichés of the Third Reich and thereby functioned as a rhetorical legitimation of Hitler’s rise to power.  相似文献

The organization of ceramic production and distribution among the ancient Hohokam of the Phoenix basin, Arizona, has been documented in recent years with much detail. Based on diverse temper and clay compositions, the provenance of individual ceramics is routinely determined with considerable precision. One exception is phyllite-tempered pottery, which was made in one corner of the basin but also across a broad upland zone adjacent to the north. The phyllite-tempered pottery from different production sources cannot be distinguished on the basis of their temper type. As shown with assays with an electron microprobe, however, both the temper and clay fractions are chemically diverse and geographically distinct, allowing many of the phyllite-tempered wares to be sourced. Among the phyllite-tempered ceramics consumed in the Phoenix basin, some are shown to have been made locally, but, surprisingly, large numbers were imported from the northern uplands. Their numbers support the idea that the connection between the Phoenix basin and the northern uplands was a prominent component of the Hohokam regional economy despite the great difference between them in settlement size and density.  相似文献

We examine the influence of various political actors on the substance and timing of presidential orders. Specifically, we analyze President John F. Kennedy’s decision to issue E. O. 11063, which directed the federal bureaucracy to eliminate discrimination in the sale or lease of residential property overseen by the federal government. We show that this order did not result solely from Kennedy’s policy preferences; rather, it was a product of persuasion by several political actors who coaxed Kennedy to act. This reinforces previous findings that the president’s power of the pen is often conditioned by the informal political costs of unilateral executive action.  相似文献

The Early to Middle Bronze Age transition in Northern Mesopotamia has received great attention for the apparent concurrence of aridification, deurbanisation, and the end of the Akkadian empire around 2200 BCE. Our understanding of the “crisis” has been almost exclusively shaped by ceramics, demography, and subsistence. Exchange and the associated social networks have been largely neglected. Here we report our sourcing results for 97 obsidian artefacts from Urkesh, a large urban settlement inhabited throughout the crisis. Before the crisis, six obsidian sources located in Eastern Anatolia are represented among the artefacts. Such a diversity of Eastern Anatolian obsidians at one site is hitherto unknown in Mesopotamia. It implies Urkesh was a cosmopolitan city with diverse visitors or visitors with diverse itineraries. During this crisis, however, obsidians came from only two of the closest sources. Two to three centuries passed before varied obsidians reappeared. Even when an obsidian source reappears, the raw material seems to have come from a different collection spot. We discuss the likely exchange mechanisms and related social networks responsible for the arrival of obsidians at Urkesh and how they might have changed in response to climatic perturbations and regional government collapse.  相似文献

Previous studies have endeavored to use petrophysical traits of obsidian, particularly its magnetic properties, as an alternative to conventional geochemical sourcing, one of the greatest successes in archaeological science. Magnetic approaches, however, have not seen widespread application due to their mixed successes. In a time when geochemical analyses can be conducted non-destructively, in the field, and in a minute or two, magnetic measurements of obsidian must offer novel archaeological insights to be worthwhile, not merely act as a less successful version of geochemistry. To this end, we report the findings of our large-scale study of obsidian magnetism, which includes 734 geological obsidian specimens and 97 artifacts measured for six simple magnetic parameters. Based on our results, we propose, rather than using magnetic properties to source artifacts to a particular obsidian flow (inter-flow sourcing), these properties are best used to differentiate quarrying sites within an individual flow (intra-flow sourcing). Our results also demonstrate that certain magnetic properties are highly affected by ancient knappers' material selection criteria. Furthermore, depending on the spatial scales of variation, which likely vary from flow to flow, we envision several potential applications of this approach, including integration into minimum analytical nodule analysis (MANA). Magnetic data appear to shift the scale of obsidian sourcing from flows to quarries and, in turn, enable new insights into raw-material procurement strategies, group mobility, lithic technology, and the organization of space and production.  相似文献
