Soviet geographers and the Great Patriotic War, 1941–1945 : Lev Berg and Andrei Grigor'ev

AbstractThe significance of the Second World War for Soviet geography was somewhat different from that in much of the West. In the USSR, as a result of the 1917 Russian Revolution and, more particularly, of Joseph Stalin's ‘Great Turn’ implemented in 1929–1933, geographers were faced with pronounced political and economic challenges of a kind which arguably only confronted most Western geographers with the onset of war. It is therefore impossible to understand the impact of the war for Soviet geography without taking into account this broader context, including events during the turbulent post-war years. The paper will focus on the experiences of two prominent geographers who played a major role in the developments of the era including their responses to the revolutionary circumstances occurring from the late 1920s, their activities and experiences during the war, and the debates and conflicts they engaged in during the post-war crisis. Some of the more significant contrasts with geographical developments in Western countries during these years will be emphasized

A Russian geographical tradition? The contested canon of Russian and Soviet geography, 1884–1953

AbstractThe paper defines a ‘geographical canon’ as those texts and authors which have been regarded as authoritative by geographers active at particular points in time. The focus is on the development of a geographical canon in Russia and the Soviet Union between the establishment of the first university geography departments in the 1880s and Stalin's death in 1953. A key 1949 meeting of the Academy of Sciences, held at a crisis point in Soviet history, is initially highlighted. The meeting's purpose was to define a canon or list of ‘founding fathers’ for each of the Soviet sciences, including geography, accenting the Russian provenance of each science. In geography's case, the ‘founding father’ selected was the eminent soil scientist, V. V. Dokuchaev (1846–1903). The paper discusses Dokuchaev's scientific achievements and questions why he was considered such an important figure by the geographers of the late Stalin era. It then analyzes some of the key works of a number of prominent geographers of the pre-revolutionary and Stalinist periods to discover how far Dokuchaev's work was emphasized. The main finding is that, although Dokuchaev and his school did have an indirect influence on geographical work from early on, only from about 1930 was his importance emphasized whilst that of the Germans was largely erased by Stalinism. The conclusion is that the geographical canon defined in 1949 was less a genuine attempt to describe the history of the discipline than a response to the priorities of the late Stalin era

Impact of a comprehensive prevention programme aimed at reducing incivility and verbal violence against healthcare workers in a French ophthalmic emergency department: an interrupted time-series study.

Primary prevention, comprising patient-oriented and environmental interventions, is considered to be one of the best ways to reduce violence in the emergency department (ED). We assessed the impact of a comprehensive prevention programme aimed at preventing incivility and verbal violence against healthcare professionals working in the ophthalmology ED (OED) of a university hospital. The programme was designed to address long waiting times and lack of information. It combined a computerised triage algorithm linked to a waiting room patient call system, signage to assist patients to navigate in the OED, educational messages broadcast in the waiting room, presence of a mediator and video surveillance. All patients admitted to the OED and those accompanying them. Single-centre prospective interrupted time-series study conducted over 18 months. Violent acts self-reported by healthcare workers committed by patients or those accompanying them against healthcare workers. Waiting time and length of stay. There were a total of 22 107 admissions, including 272 (1.4%) with at least one act of violence reported by the healthcare workers. Almost all acts of violence were incivility or verbal harassment. The rate of violence significantly decreased from the pre-intervention to the intervention period (24.8, 95% CI 20.0 to 29.5, to 9.5, 95% CI 8.0 to 10.9, acts per 1000 admissions, p<0.001). An immediate 53% decrease in the violence rate (incidence rate ratio=0.47, 95% CI 0.27 to 0.82, p=0.0121) was observed in the first month of the intervention period, after implementation of the triage algorithm. A comprehensive prevention programme targeting patients and environment can reduce self-reported incivility and verbal violence against healthcare workers in an OED. NCT02015884

Towards a reasoned 1-D river model calibration

Le calage de modèle reste une étape critique de la modélisation numérique. Après de nombreuses tentatives d`automatisation de cette tâche dans différentes domaines liés à l`eau, des questions se posent encore sur la nécessité de caler des modèles à base physique. Cet article propose aux utilisateurs de codes de calcul en hydraulique un cadre pour réaliser cette tâche selon un « code de bonnes pratiques ». Ce cadre comporte une formalisation des objets manipulés en hydraulique fluviale 1-D ainsi qu`une description conceptuelle générique du processus de calage. Ces deux éléments ont été implémentés dans un système à base de connaissances, intégrant un code de calcul ainsi que des connaissances d`experts sur le calage de modèle. Un prototype de système d`assistance au calage a ensuite été construit à l`aide d`un code de calcul résolvant les équations de Saint-Venant dans des rivières à lit fixe. Le cadre fourni pour le calage de modèle est composé de trois niveaux indépendants reliés respectivement à la tâche générique, au domaine d`application, et au code de calcul lui-même. Les deux premiers niveaux de connaissances peuvent ainsi aisément être réutilisés pour construire des systèmes d`assistance au calage pour d`autres domaines d`application, comme l`hydraulique 2-D ou encore la modélisation hydrologique à base physique. / Model calibration remains a critical step in numerical modelling. After many attempts to automate this task in water-related domains, questions about the actual need for calibrating physics-based models are still open. This article proposes a framework for good model calibration practice for end-users of 1-D hydraulic simulation codes. This framework includes a formalisation of objects used in 1-D river hydraulics along with a generic conceptual description of the model calibration process. It was implemented within a knowledge-based system integrating a simulation code and expert knowledge about model calibration. A prototype calibration support system was then built up with a specific simulation code solving subcritical unsteady flow equations for fixed-bed rivers. The framework for model calibration is composed of three independent levels related respectively to the generic task, to the application domain, and to the simulation code itself. The first two knowledge levels can thus easily be reused to build calibration support systems for other application domains, like 2-D hydrodynamics or physics-based rainfall-runoff modelling

River model calibration, from guidelines to operational support tools

Numerical modelling is now used routinely to make predictions about the behaviour of environmental systems. Model calibration remains a critical step in the modelling process and different approaches have been taken to develop guidelines to support engineers and scientists in this task. This article reviews currently available guidelines for a river hydraulics modeller by dividing them into three types: on the calibration process, on hydraulic parameters, and on the use of hydraulic simulation codes. The article then presents an integration of selected guidelines within a knowledge-based calibration support system. A prototype called CaRMA-1 (Calibration of River Model Assistant) has been developed for supporting the calibration of models based on a specific 1D code. Two case studies illustrate the ability of the prototype to face operational situations in river hydraulics engineering, for which both data quality and quantity are not sufficient for an optimal calibration. Using CaRMA-1 allows the modeller to achieve the calibration task in accordance with good calibration practice implemented in the knowledge base. Relevant reasoning rules can easily be added to the knowledge base to extend the prototype range of applications. This study thus provides a framework for building operational support tools from various types of existing engineering guidelines

V.I. Vernadsky and the noosphere concept: Russian understandings of society-nature interaction

Recent Russian legislative and policy documentation concerning national progress towards sustainable development has suggested that the attainment of such a state would represent the first stage in the development of the noosphere as outlined by the Russian scientist Vladimir Ivanovich Vernadsky (1863–1945). This paper explores Vernadsky’s model of evolutionary change through a focus on his work on the biosphere and noosphere in an attempt to further understanding of the way in which Russia is approaching the concept of sustainable development in the contemporary period. It is argued that the official Russian interpretation of the noosphere idea tends to obscure the evolutionary and materialist foundations of Vernadsky’s biosphere–noosphere conceptualisation. At the same time, the concluding section of the paper suggests that the scope of Vernadsky’s work can be used to stimulate the search for a more coherent approach to work in areas of sustainable development and sustainability across the span of the social and physical sciences

Totalitarianism and geography: L.S. Berg and the defence of an academic discipline in the age of Stalin

In considering the complex relationship between science and politics, the article focuses upon the career of the eminent Russian scholar, Lev Semenovich Berg (1876–1950), one of the leading geographers of the Stalin period. Already before the Russian Revolution, Berg had developed a naturalistic notion of landscape geography which later appeared to contradict some aspects of Marxist–Leninist ideology. Based partly upon Berg's personal archive, the article discusses the effects of the 1917 revolution, the radical changes which Stalin's cultural revolution (from the late 1920s) brought upon Soviet science, and the attacks made upon Berg and his concept of landscape geography thereafter. The ways in which Berg managed to defend his notion of geography (sometimes in surprisingly bold ways) are considered. It is argued that geography's position under Stalin was different from that of certain other disciplines in that its ideological disputes may have been regarded as of little significance by the party leaders, certainly by comparison with its practical importance, thus providing a degree of ‘freedom’ for some geographers at least analogous to that which has been described by Weiner (1999. A little corner of freedom: Russian nature protection from Stalin to Gorbachev. Berkeley: University of California Press) for conservationists. It is concluded that Berg and others successfully upheld a concept of scientific integrity and limited autonomy even under Stalinism, and that, in an era of ‘Big Science’, no modernizing state could or can afford to emasculate these things entirely

True Superconductivity in a 2D "Superconducting-Insulating" System

We present results on disordered amorphous films which are expected to undergo a field-tuned Superconductor-Insulator Transition. Based on low-field data and I-V characteristics, we find evidence of a low temperature Metal-to-Superconductor transition. This transition is characterized by hysteretic magnetoresistance and discontinuities in the I-V curves. The metallic phase just above the transition is different from the "Fermi Metal" before superconductivity sets in.Comment: 3 pages, 4 figure
