A study on the assessment of the production costs curves in micro-grids
2013
In micro-grids, due to their small scale, there is commonly only one power supplier. A competitive wholesale market hardly exists, so the question about how to consider market issues for small producers within micro-grids arises. On the other hand, the specific features of micro-grids where load and generated power hardly find a balance, require that customers take part to regulation issues, also using demand-response (DR) programs. In this paper, price responsive (PR) policies and their programs are discussed to answer this question. A case study of a micro-grid with one micro-turbine and two photovoltaic (PV) generators is analyzed to assess the overall production cost in order to build a…
Economic Sustainability of Italian Greenhouse Cherry Tomato
2014
Greenhouse tomato cultivation plays an important role in Sicily, being the primary production area in Italy, due to its favorable pedo-climatic conditions that permit extra-seasonal productions. In Sicily, more than half of greenhouse tomato production is derived from the Province of Ragusa on the southeastern coast, where especially cherry tomato typologies are cultivated. Over the last decade, the Ragusa Province has registered a decrease both in terms of greenhouse tomato area and harvested production due to several structural problems that would require restructuring of the tomato supply chain. Thus, since recognition of real costs and profitability of tomato growing is a vital issue, b…
Cultivation and nutritional value of Pleurotus nebrodensis
2013
A detailed report on Pleurotus nebrodensis cultivation methodologies, production costs, main pests and diseases and their control techniques is presented, together with information about the nutritional value and medicinal properties of the mushroom.
Measurement of an Excess in the Yield of J/ψ at Very Low pT in Pb-Pb Collisions at √sNN = 2.76 TeV
2016
We report on the first measurement of an excess in the yield of J=ψ at very low transverse momentum (pT < 0.3 GeV=c) in peripheral hadronic Pb-Pb collisions at √sNN=2.76 TeV, performed by ALICE at the CERN LHC. Remarkably, the measured nuclear modification factor of J=ψ in the rapidity range 2.5 <y< 4 reaches about 7 (2) in the pT range 0–0.3 GeV=c in the 70%–90% (50%–70%) centrality class. The J=ψ production cross section associated with the observed excess is obtained under the hypothesis that coherent photoproduction of J=ψ is the underlying physics mechanism. If confirmed, the observation of J=ψ coherent photoproduction in Pb-Pb collisions at impact parameters smaller than twice the nu…
Planning Production Preparation Processesusing The Critical Chain Method
2017
This paper explains the usefulness of critical chain project management for planning production preparation processes. A synthesis of issues of project management and production preparation processes is presented, and a conceptual model of concurrent design processes using the critical chain method is developed. The proposed model of planning production preparation processes enables improving the effectiveness and economic efficiency of new product development. The main assessment indicators of efficient project management in production preparation are: shortening the preparation time of new product development, rational use of resources, and reducing the risk of failure. The proposed appro…
Peut-on concilier un faible usage de pesticides, une bonne performance économique et environnementale ? Analyse d’un réseau national de fermes de dém…
2017
Feeding an increasing world population with a sustainable agriculture is one of the greatest challenges of this century. The reduction of the reliance on pesticides is a critical aspect in this quest for sustainability. Whether cropping systems with reduced reliance on pesticides would be able to reconcile the various components of sustainability remains however a matter of debate. Are they as productive and profitable than current mainstream cropping systems? Here the objective is to study the feasibility of a reduced reliance on pesticides in France. We used a unique dataset from a national network of more than thousand arable commercial farms between 2009 and 2011. Launched in the framew…
Analysing the relationship between yields and farmers' incomes to help the design of more sustainable cropping systems
2022
Farmers often grow only the few high-yielding crops in the area, and target maximum yields through high levels of inputs. These practices are based on the assumption of a positive relationship between productivity and profitability over a wide range of cropping systems (Woo et al., 2020; Erythrina et al., 2021). Part of the correlation between productivity and profitability could be related to differences in production situation and therefore yield potential, i.e. characteristics that do not depend on farmers’ decisions. For a given production situation, the systems with the highest profitability and the best environmental sustainability could be systems with moderate yields. The objective …
La Investigación Acción Participativa (IAP) en el sector empresarial. Interviniendo desde lo local
2019
El artículo muestra el potencial de aplicación de las metodologías participativas de investigación y planeación social para una gestión participativa del conocimiento y el desarrollo de estrategias de intervención en el territorio. En este contexto se muestra una investigación realizada en base a metodologías de investigación acción-participación implementadas en una iniciativa empresarial de una localidad de la Comunidad Valenciana. Así, el carácter influyente y la capacidad de integrar saberes, conocimientos y aprendizajes de los diversos actores sociales e institucionales favorecen la promoción y el desarrollo de estrategias capaces de dar respuesta a las distintas problemáticas existent…
Crecimiento económico y productividad en Latinoamérica. El proyecto LA-KLEMS
2017
Antecedentes: El objetivo de este artículo es analizar el crecimiento económico, la productividad y sus determinantes en cinco países de América Latina (Argentina, Brasil, Chile, Colombia y México) durante el periodo 1990-2010. Este análisis se aplica tanto a la economía agregada como a nueve sectores de actividad económica. Metodología: Se utiliza una nueva base de datos, LA-KLEMS, que servirá como herramienta fundamental para la investigación empírica y teórica en el área de crecimiento económico y productividad para América Latina. Las variables se organizan en torno a la metodología de contabilidad del crecimiento, que proporciona un marco conceptual claro para el análisis coherente de …
Crecimiento y competitividad: Los desafíos de un desarrollo inteligente
2014
Las reformas económicas e institucionales y de las estrategias puestas en marcha por los agentes privados y públicos deben tener como objetivo un desarrollo inteligente. ¿Cómo lograrlo? Combinando tres elementos: 1) Un crecimiento apoyado en factores productivos de calidad —en especial el capital humano y tecnológico— y mejoras continuas de la productividad de las organizaciones; 2) Unas políticas atentas a la igualdad de oportunidades en el acceso al trabajo y los servicios públicos básicos; y 3) Una preocupación por lograr mejoras de bienestar para las generaciones presentes sin impactos sobre el medio ambiente que pongan en riesgo el bienestar de las generaciones futuras. El Informe indi…
