东北工业旅游研究--振兴老工业基地的新视角

振兴东北老工业基地需从多方面入手,工业旅游是其中的重要手段之一。东北地区工业旅游资源丰富,是新中国工业的发源地,创造了共和国工业历史上的多个第一,并为全国各地的工业建设输送了大量的原材料、工业装备和工程技术人员,做出了无私的奉献,对全国游客有着强大的吸引力,具有发展工业旅游的良好条件。发展工业旅游有利于扩大就业、树立良好的企业和城市形象;有利于推动企业调整产业结构,提高生产技术水平;对老工业基地的振兴将产生积极的作用和影响。本文还提出了发展工业旅游的若干战略措施。     

Der Ort des rhetorischen Wissens Kunst und Natur bei Isokrates

This paper poses the question of the place of rhetoric as a discipline. It addresses the topical demand that nature, art, and exercise have to be combined by way of an analysis of Isocrates' Against the Sophists. Its thesis is that the call for a “combination” of art and nature solves the disciplinary problems of rhetoric, even though such a synthesis is in fact inconceivable. Rhetoric is not a science, and does not have access to a methodical correlation of rhetorical strategies and their effects upon the audience. Isocrates' criticism of those rhetoricians who assume that their art could be taught in much the same way as the art of writing is of paramount importance here. The case of Isocrates is instructive because it shows how rhetorical success depends on re-designing the institutional structure of rhetoric and on the capacity to cope with its lack of methodical knowledge. As a result of its para-scientific nature, rhetoric refers to various models and metaphors to present itself as a discipline. Of these the orator perfectus, the orator imperfectus, and the sophist model of the art of writing as criticized by Isocrates are discussed. This paper attempts a rhetorical reading of the discourse of rhetoric by exploring the implications of these metaphors. At the same time it argues for a history of science which does not shrink away from an analysis of such para-sciences as rhetoric. It is precisely the lacking scientificity of rhetoric as a discipline which warrants increased attention from the point of view of the history of science.     

Applying the technique of image classification to climate science: the case of Andalusia (Spain)

This paper proposes an empirical climate classification method based on the application of multivariate statistics. In this method, the technique of supervised and unsupervised image classification is used to classify the data and define climatic units. envi software is used to perform the image classification, specifically, the Iterative Self‐Organizing Data Analysis Technique algorithm. Supervised classification is also applied based on reference variables, fundamental parameters and a classifier. The obtained results display greater objectivity, reliability, operability, accessibility and reproducibility than previous climate classifications devised for the region of Andalusia (Spain), taking into account that these previous classifications were not based on quantitative criteria.     

THE LAST EUROPEAN: A PLEA FOR A RE‐POLITICIZED BENJAMIN

This review of Alexander Gelley's captivating book follows its attempt to respond to Benjamin's plea to “expound the nineteenth century” and liberate us “from the stupendous forces of history,” using aisthesis, “a weak messianic force,” and “dream visions.” Taking the cue from Gelley's reference to Benjamin's rebellion against “a secret agreement between past generations and the present one” (156), this review attempts to open up the context and to wonder about “the secret agreement” between recent Benjamin scholarship and its own sense of the past. The review pleads with future Benjaminians to start asking questions relating to the twentieth century, and attempts to consider the relevance of Benjaminia for current political analysis and recent trends in critical studies.     

An der Schwelle zum Atomzeitalter. Die Vorgeschichte der Entdeckung der Kernspaltung im Dezember 1938

On the Threshold of the Atomic Age: The History of the Discovery of Nuclear Fission in December 1938: - Fifty years ago in mid-December 1938, Otto Hahn and Fritz Strassmann at the Kaiser Wilhelm Institute of Chemistry discovered nuclear fission by demonstrating, using chemical methods, the presence of barium in the decay products of neutron-irradiated uranium. This essay points out the constellation of conditions and prerequisites (Historischer Erfahrungsraum/“historical field of experience”) which led to the discovery of nuclear fission, and was constituted by specific components (“presentabilia”) both internal and external to science in general and to atomic research in particular. A decisive role was played by the constellation of the three members of the Berlin team and their personal situations under the political conditions of the 1930s. Further “presentabilia” were the institutional, instrumental and disciplinary conditions under which the team worked and the methods available to the individual members of the team. It was very important that some of the “presentabilia” were “not-present” to the members of the team. In particular, after Meitner's departure from Berlin Hahn and Strassmann had no access to methods and tools for proving the presence of alpha rays; nothing was known of the existence of actinides; no cyclotron or other source of neutrons more productive than those already in use in Berlin, Paris and Rome was available; it was very important that Strassmann and Hahn were not convinced of the strong validity of the resonance process induced by thermal neutrons; etc.     

New Light on the Medieval Gough Map of Britain

Remarkably little is known about the earliest surviving separate-sheet medieval map of Britain that takes its name from its former owner, Richard Gough (1735–1809), and that has been variously dated to between 1300 and 1400, and later. It presents a sophisticated cartographical image at a time when detailed maps of individual regions were almost unknown in Europe, yet nothing is agreed about its possible origins, context (ecclesiastical or secular), or why and how it was compiled. In the belief that historical interpretation has to stem from an intimate knowledge of the map as artefact—the state of the parchment, nature of the inks, palaeography—as well as image, an informal study group of historians and scientists (the Gough Map Panel) was convened in 2012 to examine the map through high resolution digital reproduction, hyperspectral analysis, three-dimensional analysis and Raman pigment analysis. Although the study is still ongoing, much that is new has been discovered, notably about the way features were marked on the map, Gough’s application to the map of a damaging reagent to render place-names readable, and the extent to which the original map (now dated to c.1400), although never completed, was nonetheless reworked on two different occasions in the fifteenth century, effectively creating two further maps. These and other findings are summarized here to encourage the further study of the map’s features that is needed before it can be fully understood.
