Infrastructures agroécologiques en droit
2017
International audience; Les infrastructures agroécologiques (IAE) sont une notion récente désignant des éléments naturels, culturels et paysagers, tels les mares, les landes, les haies, les talus, les fossés, les arbres, les bosquets, les bandes enherbées le long des cours d’eau, les murets de pierre ou encore les terrasses. Pendant des siècles, ces milieux physiques sont passés inaperçus pour le droit. Attachés au foncier, ils n’en constituaient qu’un accessoire sommé de suivre le régime juridique du principal. Ces infrastructures étaient sous l’entière maîtrise du propriétaire immobilier pouvant, à sa guise, les créer ou les faire disparaître. Leur statut a cependant c…
Urban Infrastructure and Euergetism Outside the City of Rome
2015
This chapter explores the connection between the monumentalization of cities, the use of local resources, and the involvement of benefactors in civic building operations. At its peak the Roman Empire comprised a mosaic of some two thousand flourishing cities. For the establishment and maintenance of their infrastructure, they benefited in large part from the contributions of wealthy citizens and, in some situations, of outside sponsors. This chapter uses epigraphic evidence to explain what financial resources cities had at their disposal and who was responsible for benefactions that benefited the communities and their inhabitants. It also discusses the nature of the benefactions and what su…
A Triple-Helix Model of Sustainable Government Information Infrastructure: Case Study of the eProcurement System in the Indonesian Public Sector
2013
Lack of sustainability is one of the problems in information system (IS) implementation in developing countries, such as Indonesia. More specifically, this is the case in eGovernment implementation. Using an interpretive research stance in a case study of the eProcurement system in the public sector, the study reveals that the concept of information infrastructure (II) can be used to understand the sustainability issue. Findings suggest that applying the concept of II in IS development and implementation can improve the sustainability of an IS in the public sector, especially one that is used across government agencies and levels. The paper proposes a triple-helix model of a government II c…
Innovation in the Rural Areas and the Linkage with the Quintuple Helix Model
2016
Abstract In this paper we analyze some specific conditions for local development. Our interest is oriented towards a multidimensional aspect of peripheral and rural areas. The rural areas considered as a productive system reflects a strong relationship between the agriculture and the other economic activities, In addition eco-systems must be protected and enhanced to develop innovation models that propose new roles and responsibilities for a new development vision. Following the implementation of the Smart Specialization Strategy and the Quintuple Helix Model this paper underlines the importance of connecting the innovation process with rural territories. We have considered some environment…
A systematic assessment of road pavement sustainability through a review of rating tools
2017
Pavements are engineered systems present in every modern society, and they have significant environmental, economic and social impacts. In an effort to promote more sustainable decisions regarding pavement design, construction and management, several pavement sustainability assessment tools have been developed. This research reviewed some of these tools and found that many of them do not treat the pavement as a system; instead, they seek to optimize individual aspects of the pavement in an effort to increase its sustainability. Therefore, a framework for analytically assessing the system outcomes towards sustainable objectives is presented and applied for modern pavement sustainability asse…
A problem-adjusted genetic algorithm for flexibility design
2013
Many present markets for goods and services have highly volatile demand due to short life cycles and strong competition in saturated environments. Determination of capacity levels is difficult because capacities often need to be set long before demand realizes. In order to avoid capacity-demand mismatches, operations managers employ mix-flexible resources which allow them to shift excess demands to unused capacities. The Flexibility Design Problem (FDP) models the decision on the optimal configuration of a flexible (manufacturing) network. FDP is a difficult stochastic optimization problem, for which traditional exact approaches are not able to solve but the smallest instances in reasonable…
Regulation of Investments in Infrastructure: The Interplay between Strategic Behaviors and Initial Endowments
2012
This paper explores the dynamic properties of price-based policies in a model of competition between two jurisdictions. Jurisdictions invest over time in infrastructure to increase the quality of the environment, a global public good. They are identical in all respects but one: initial stocks of infrastructure. This is a dynamic type of heterogeneity that disappears in the long run. Therefore, at the steady state, usual intuitions from static settings apply: identical jurisdictions inefficiently underinvest, calling for public subsidies. In the short run, however, counterintuitive properties are established: (i) the evolution of capital stocks can be nonmonotonic and (ii) one jurisdiction c…
Determinants of COVID-19 Vaccine Rollouts and Their Effects on Health Outcomes
2022
Background Vaccination against the coronavirus disease (SARS-CoV-2) is understood to be the key way out of the COVID-19 pandemic. Limited evidence exists on the determinants of vaccine rollouts and their health effects at the country level. Objective Examine the determinants of COVID-19 vaccine rollouts and their effects on health outcomes. Methods Ordinary least squares regressions with standard errors clustered at the country level for Cross-section and Panel daily data of vaccinations and various health outcomes (new COVID-19 cases, fatalities, intensive care unit (ICU) admissions) for an unbalanced sample of about 200 countries during the period 16 December 2020 to 20 June 2021. Results…
Infrastructures and Productivity in the Spanish Regions
1996
The aim of this paper is to analyse the role of public capital, the types of infrastructures in which it is invested, and their territorial distribution in the gains in productivity of the private sector in the Spanish regions in the period 1964-1991 using panel data techniques to control for unobserved state-specific characteristics. The results obtained show how the infrastructures most directly linked to the productive process present a significant and positive effect on productivity. They also show the importance of the network effect of the infrastructures of a productive nature as well as a decrease in the elasticity associated with such infrastructures as development progresses. El p…
Strategie ecosistemiche e infrastrutture verdi in simbiosi con il costruito
2022
Il numero 11 di AGATHÓN raccoglie saggi, studi, ricerche e progetti sul tema Vegetazione | La sua Simbiosi con il Costruito richiamando il ruolo che la Natura in generale e la Vegetazione in particolare possono svolgere nel breve periodo per affrontare l’attuale sfida del surriscaldamento globale e dei cambiamenti climatici causati da deforestazioni e incendi boschivi, urbanizzazioni selvagge, uso indiscriminato di materie prime non rinnovabili e incremento delle emissioni di anidride carbonica, tutti fattori che determinano un impatto devastante sul nostro ormai fragile ecosistema, sulla società e sull’economia. Se Simon aveva intuito già nel 1969 il potenziale di una ‘nuova ecologia’ in c…
