Fragtique: Applying an OO Database Distribution Strategy to Data Warehouse
2001
We propose a strategy for distribution of a relational data warehouse organized according to a star schema. We adapt fragmentation and allocation strategies that were developed for OO databases. We split the most-often-accessed dimension table into fragments by using primary horizontal fragmentation. The derived fragmentation then divides the fact table into fragments. Other dimension tables are not fragmented since they are presumed to be sufficiently small. Allocation of fragments encompasses duplication of non-fragmented dimension tables that we call a closure.
Symmetry as an Intrinsically Dynamic Feature
2010
Symmetry is one of the most prominent spatial relations perceived by humans, and has a relevant role in attentive mechanisms regarding both visual and auditory systems. The aim of this paper is to establish symmetry, among the likes of motion, depth or range, as a dynamic feature in artificial vision. This is achieved in the first instance by assessing symmetry estimation by means of algorithms, putting emphasis on erosion and multi- resolution approaches, and confronting two ensuing problems: the isolation of objects from the context, and the pertinence (or lack thereof) of some salient points, such as the centre of mass. Next a geometric model is illustrated and detailed, and the problem …
Vita di un impero: tracce di metafore biologiche in Tucidide
2019
Although we do not find in the narrative of the Peloponnesian War an explicit analogy between the phases of human life (more or less distributed) and those of the great political bodies, it remains nevertheless fruitful in my opinion to explore the text in search of clues for biological metaphors. In particular, I will follow the traces left throughout the narrative by three crucial elements: daring (τόλμα), desire (ἔρως), disease (νόσος). The biological metaphor of the 'degrees of development' of the living being in Thucydides does not find fulfillment in the senectus. His absence was charged by Reinhart Koselleck as a distinctive feature of Greek historiography, especially of the classica…
Ensemble reconstruction constraints on the global carbon cycle sensitivity to climate
2010
The processes controlling the carbon flux and carbon storage of the atmosphere, ocean and terrestrial biosphere are temperature sensitive and are likely to provide a positive feedback leading to amplified anthropogenic warming. Owing to this feedback, at timescales ranging from interannual to the 20-100-kyr cycles of Earth's orbital variations, warming of the climate system causes a net release of CO(2) into the atmosphere; this in turn amplifies warming. But the magnitude of the climate sensitivity of the global carbon cycle (termed gamma), and thus of its positive feedback strength, is under debate, giving rise to large uncertainties in global warming projections. Here we quantify the med…
Exposure assessment of a burning ground for chemical ammunition on the Great War battlefields of Verdun
2007
The destruction of arsenical shells from the 1914/18 war in the vicinity of Verdun (France) during the 1920s resulted in a locally limited but severe soil contamination by arsenic and heavy metals. At the study site, the main part of the contaminant inventory occurs in the upper 20 cm of the topsoil which is essentially composed of combustion residues. Besides, some Cu (cmax.=16,877 mg/kg) and Pb (cmax.=26,398 mg/kg) in this layer, As (cmax.=175,907 mg/kg) and Zn (cmax.=133,237 mg/kg) were detected in very high concentrations. The mobilities of Cu, Mn, Pb and Zn in the soil system were derived from ammonium nitrate eluates. They are strongly influenced by the soil pH and can be described by…

Northern peatlands have accumulated large stocks of organic carbon (C) and nitrogen (N), but their spatial distribution and vulnerability to climate warming remain uncertain. Here, we used machine-learning techniques with extensive peat core data (n > 7,000) to create observation-based maps of northern peatland C and N stocks, and to assess their response to warming and permafrost thaw. We estimate that northern peatlands cover 3.7 ± 0.5 million km2 and store 415 ± 150 Pg C and 10 ± 7 Pg N. Nearly half of the peatland area and peat C stocks are permafrost affected. Using modeled global warming stabilization scenarios (from 1.5 to 6 °C warming), we project that the current sink of atmospheri…
Leadership ethical dimension: a requirement in TQM implementation
2002
Deals with theoretical arguments that justify why the leadership of managers and its ethical dimension is a powerful enabler for TQM efforts to sustain, together with a systematic management. Starts by setting out a multidimensional conception of leadership in which the ethical sphere is explicitly considered. The principles articulating TQM are then analysed, studying the role of leadership and its ethical dimension, in their implementation. Concludes with five propositions, stating that the explicit consideration of leadership’s ethical dimension is required in order to achieve a complete, deep and sustained deployment of TQM principles. Draws implications for managers and researchers.
Are tariffs bad for growth? Yes, say five decades of data from 150 countries☆
2020
Abstract The empirical evidence on the growth effects of import tariffs is sparse in the literature, notwithstanding strong views held by the public and politicians. Using an annual panel of macroeconomic data for 151 countries over 1963–2014, we find that tariff increases are associated with an economically and statistically sizeable and persistent decline in output growth. Thus, fears that the ongoing trade war may be costly for the world economy in terms of foregone output growth are justified.
