Processi di accumulazione e degrado del “capitale intellettuale” nel governo dello sviluppo aziendale Una prospettiva basata sulla dinamica delle ris…
2012
Sempre più spesso oggi le fonti del vantaggio competitivo dell’impresa non risiedono in singoli fattori della produzione (sebbene disponibili in quantità limitata, difficilmente imitabili o sostituibili da parte dei concorrenti), quanto piuttosto nella capacità di saper individuare e mantenere un opportuno dimensionamento quali-quantitativo di risorse strategiche tangibili e intangibili. Tra queste ultime, il “capitale intellettuale” assume una particolare rilevanza. Per comprendere i meccanismi sottostanti all’acquisizione di un vantaggio competitivo sostenibile è necessario cogliere i processi dinamici di accumulazione e degrado del “capitale intellettuale” e delle altre risorse strategic…
A Multi objective inventory model for short food supply chains
2017
Over the past 50 years, vertically integrated multinationals dominated global food markets by providing huge product diversity at low prices. Such systems are characterized by long supply chains capable of achieving high cost efficiencies resulting from the use of cheap raw materials, high chemical inputs, industrial shelf-life extension processes, economies of scale and mechanization. This dominant position on the market, however, has been achieved at a heavy cost on the global environment, generated by massive food wastage, and by a steady supply of fossil fuels. For such reasons, global supply chains are considered unsustainable and new food systems are being promoted in order to replace…
De la performance musicale dans la Guyane traditionnelle : expression cognitive singulière d?une musique-verbe
2021
Guianese culture and traditional music, here evoked, are various. It is more a transcultural process that, along centuries, gave an original result born in the Americas, in Guiana in this case. It is a form of refoundation, of recreation of cultures and new human beings generally called Creoles. The musical performance, that I study here, is the echo of social and cultural space of this reformulation of thought, life, and conception of the world. It is, as well, a mean of transposition and transformation of the values issued of diverse sources and categories. It is in no way a second-rate cultural practice, as it is the place where were born philosophies and actions for common life as well …
First volatile inventory for Gorely volcano, Kamchatka
2012
We report here the very first assessment of volatile flux emissions from Gorely, an actively degassing volcano in Kamchatka. Using a variety of in situ and remote sensing techniques, we determined the bulk plume concentrations of major volatiles (H2O 93.5%, CO2, 2.6%, SO2 2.2%, HCl 1.1%, HF 0.3%, H2 0.2%) and trace-halogens (Br, I), therefore estimating a total gas release of 11,000 tons·day−1 during September 2011, at which time the target was non-eruptively degassing at 900°C. Gorely is a typical arc emitter, contributing 0.3% and 1.6% of the total global fluxes from arc volcanism for CO2 and HCl, respectively. We show that Gorely's volcanic gas (H2O/SO2 43, CO2/SO2 1.2, HCl/SO2 0.5) is a…
“Beyond Weather Regimes”: Descriptors Monitoring Atmospheric Centers of Action. A case study for Aotearoa New Zealand
2021
AbstractThis paper introduces a set of descriptors applied to weather regimes, that allow for a detailed monitoring of the location and intensity of their atmospheric centers of action (e.g. troughs and ridges) and the gradients between them, when applicable. Descriptors are designed to document the effect of climate variability and change in modulating the character of daily weather regimes, rather than merely their occurrence statistics.As a case study, the methodology is applied to Aotearoa New Zealand (ANZ), using ERA5 ensemble reanalysis data for the period 1979-2019. Here, we analyze teleconnections between the regimes and their descriptors, and large-scale climate variability. Result…
Coupled petrological-geodynamical modeling of a compositionally heterogeneous mantle plume
2018
Abstract Self-consistent geodynamic modeling that includes melting is challenging as the chemistry of the source rocks continuously changes as a result of melt extraction. Here, we describe a new method to study the interaction between physical and chemical processes in an uprising heterogeneous mantle plume by combining a geodynamic code with a thermodynamic modeling approach for magma generation and evolution. We pre-computed hundreds of phase diagrams, each of them for a different chemical system. After melt is extracted, the phase diagram with the closest bulk rock chemistry to the depleted source rock is updated locally. The petrological evolution of rocks is tracked via evolving chemi…
Unusual business or business as usual: An investigation of meeting support requirements in multilateral diplomacy
1993
Abstract The concept of supporting meetings at the same time and at the same place with computers raises the problem of how salient features of group behaviors are understood in meetings. In this paper we critically examine some aspects of meeting behaviors. We point out that the idea of small, cohesive business teams is not necessarily a valid starting point in thinking of all meeting support. In particular, beliefs that relate to user aspects, group features such as composition, structure and protocols, and task characteristics such as nature, importance, and goals in meetings may need deliberation in many group decision support systems (GDSS) interventions. To demonstrate the credibility…
Leadership Team Tool for better meaning making
2016
Purpose– The purpose of this paper is to present a Leadership Team Tool for developing reflexivity in the context of leadership teams.Design/methodology/approach– The Leadership Team Tool is based on the theoretical premises of seeing communication as meaning making, and therefore placing discourse and conversation in the center of developing leadership teams.Findings– The paper illustrates how reflexivity can be facilitated through a structured process of using the Leadership Team Tool. An empirical investigation of using the tool in an authentic leadership team setting is warranted to further develop the Leadership Team Tool.Originality/value– The paper makes a practical contribution to s…
Water Conflict and Water Management in the Middle East
2004
“Water is Life”: this is often forgotten in countries with abundant water ressources. As a ressource it only gains importance once it is in short supply or once its quality declines. In the case of shortage the battle for water becomes inevitable. At the moment we have up to 200 conflicts of border-crossing water systems in the world. The Middle East is considered to be a typical example of this politically significant problem
The Physical Economy of France (1830–2015). The History of a Parasite?
2019
Abstract This article explores long-term trends and patterns of material use in France for a 185-year period. It is the first long-term study of material flows for France with national and yearly data for most of the period. Based on a material flow analysis (MFA) that is fully consistent with current standards of economy-wide MFAs and covers domestic extraction, imports, and exports of materials, we investigated the evolution of the French metabolism from industrialization to financialized capitalism. Over the whole period, there is a 9-fold increase in domestic material consumption, an expansion of material use per capita, and a spectacular addition of abiotic resources (fossil fuels and …
