Shaping the firm's external search strategy
2014
This paper explores the determinants of external knowledge search strategies, specifically, exploitative and exploratory search. The literature emphasizes environmental context and technological resources, especially R&D, as important determinants of the search strategy. In this paper we focus on two types of the firm's formal structure: formalized and decentralized structures. The study uses survey data from the ceramic tile industry in Spain. The results show that a competitive environment and a decentralized organizational structure play a role in shaping the firm's external search strategy, but that R&D has no effect. We find that competition inhibits exploratory search, while a decentr…
Competitive versus efficient extraction of a common property resource: The groundwater case
2001
Abstract In this paper socially optimal and private extraction of a common property aquifer are compared. Open-loop equilibrium and feedback equilibrium in linear strategies have been computed to characterize private extraction. The use of these two equilibrium concepts allows us to distinguish between cost and strategic externalities as long as the open-loop solution captures only the cost externality, and the feedback solution captures both. The results show that strategic behaviour increases the overexploitation of the aquifer compared to the open-loop solution. However, if the groundwater storage capacity is large, the difference between the socially optimal and private extraction, the …
Migrazioni forzate e diritti disattesi. Lo sguardo di genere sui bisogni di frontiera
2021
La definizione di “tratta di esseri umani”, adottata dal Protocollo delle Nazioni Unite, descrive gli elementi che identificano un fenomeno rilevato su scala mondiale che occupa i primissimi posti delle classifiche relative ai crimini internazionali per la diffusione e la numerosità di casi. Esso prevede l’induzione forzata a varie forme di sfruttamento e, fra queste, un posto di rilievo occupa quello relativo allo sfruttamento a scopo prostitutivo. Malgrado accordi europei e leggi nazionali convergano sul piano giuridico, allo stato attuale, la condizione di “vittima di tratta” fatica ad essere riconosciuta come tale da un sistema di protezione e accoglienza che in Europa evidenzia procedu…
Poner el trabajo al servicio de un proyecto de vida : estrategias contra la precariedad
2019
A partir de 20 historias de vida, este artículo se propone presentar las estrategias que algunos jóvenes italianos altamente cualificados han encontrado para eludir la doble amenaza de la precariedad laboral y de la invasión del trabajo en la vida. Centrando sus biografías en un proyecto de innovación social o ligado a la vertiente expresiva del trabajo, los jóvenes investigados se han enfrentado a un destino de explotación, incertidumbre, fragmentación e individualización del itinerario laboral y vital, común a una generación entera. Se ha utilizado la técnica de la entrevista en profundidad. La investigación ha permitido identificar en sus discursos las siguientes estrategias: 1) colocar …
LA TRANSMISSION DE L'ENTREPRISE AGRICOLE EN SOCIÉTÉ
2017
National audience; La société, comme outil de transmission de l’entreprise agricole, suscite à la fois fascination et méfiance. En cette technique juridique reposent les espoirs de simplification et d’unification de la cession du patrimoine productif. Mais derrière le voile de la personnalité morale, se cache une réalité plus nuancée, tant les liens qui unissent les hommes à la terre ne sont pas toujours solubles dans la fiction sociétaire.
La transmission de l’exploitation agricole à l’épreuve des obligations environnementales
2017
National audience; Longtemps tenues pour négligeables, les problématiques environnementales représentent dorénavant un aspect majeur de la transmission des exploitations agricoles. Que les obligations écologiques soient attachées aux biens formant l’outil de production ou à la personne de l’exploitant qui les a souscrites, leur sort interfère avec la cession de l’entreprise agricole.
Les impacts du campagnol terrestre sur les systèmes fourragers : le cas de l’élevage bovin allaitant en Bourgogne
2014
EAAgroSupECOLDUR; Do vole outbreaks have the same effects on suckler beef farms in Burgundy as they do on daily farms in Auvergne and Franche-Comte? Semi-structured interviews were carried out with 19 farmers from Burgundy who had been affected by a water vole outbreak in 2011. The results indicate that, just like farmers in Auvergne and Franche-Comte, farmers in Burgundy witnessed a decrease in forage quantity and quality. Farmers used diverse measures to deal with the outbreak (e.g., avoidance strategies or the use of bromadiolone). Farmers that described water voles as pests were more likely to have used bromadiolone, while those who described water voles in morphological terms or in ter…
Evaluation agroécologique de systèmes de culture en zone tropicale humide : Cas de la mise en valeur agricole d'une savane herbacée acide (Plaine des…
2013
Dans les régions tropicales humides, concilier intensification agricole et protection des ressources naturelles est un défi majeur et difficile à relever. Dans les savanes acides du nord-est laotien, des systèmes de culture de semis direct sur couverture végétale (SCV), basés sur les trois principes du non-labour, d’une couverture permanente du sol, et sur la pratique de rotations culturales diversifiées, sont proposés comme alternative technique à l’intensification agricole conventionnelle basée sur le labour. Si ces systèmes ont connu une diffusion importante et rapide dans les grandes agricultures mécanisées, leur diffusion reste néanmoins à ce jour limitée en contexte de petite agricult…
Cropping system dynamics, climate variability, and seed losses among East African smallholder farmers: a retrospective survey.
2014
Abstract Climate variability directly affects traditional low input and rain-fed farming systems, but few studies have paid attention retrospectively to the cropping system’s ability to mitigate climate risk. This study analyzes the impacts of rainfall variability on farmers’ seed variety losses over time, considering changes in smallholder farming systems. The cropping system dynamics, in favoring maize at the expense of sorghum and pearl millet, have induced an increasing risk of seed loss during drought. Combining ecological anthropology and climatology, a retrospective survey asking farmers about the period 1961–2006 was carried out at three altitudinal levels (750, 950, and 1100 m) on …
Gestion du pâturage au printemps en système bovin allaitant : diversité des pratiques en Saône-et-Loire
2009
National audience; Grazed grass is the cheapest forage for making meat'. In order to incite farmers to make their forage systems more self-sufficient and thrifty, the 'Chambre d'Agriculture de Saone-et-Loire' (a professional agricultural organization for that departement) has been monitoring for five years the management of spring grazing on 23 farms. The analysis of farmers' practices lead to considerations as to put to the best use the grazed grass, according to the pedo-climatic conditions and the constraints of the farms. With the aim of optimizing the pasture resources in order to limit the purchase of concentrates and to cope with the climatic hazards, the study of the management of s…
