Diffusion of Software Technology Innovations in the Global Context

2002

This study examines how software businesses are acquiring new software technology innovations (STIs) in rapidly changing globalized business environment characterized by rapidly shortening software technology life cycles, changing customer demands, and intense competition. It was executed through both theoretical and empirical investigations and analyses. It describes one case company as an example of the diffusion of STI and develops a framework for the diffusion of software technology innovation. The research findings are useful for both further research and industrial settings. peerReviewed

International audience

A soil biodiversity survey coupled with the national soil quality monitoring network?

2021

International audience; Despite its importance for human activities, soil biodiversity remains largely unknown and threatened. Aware of the need for large-scale monitoring, we studied the feasibility to add a soil biodiversity survey (RMBS-Biodiversity) to the already existing French soil quality monitoring network (RMQS). We worked with soil biodiversity experts to couple RMBS-Biodiversity with RMQS i.e. to choose soil taxons and functions, the methodologies and the sampling design. According to the experts, the sampling design of RMQS fits with a soil biodiversitysurvey. We propose sampling protocols for i) bacteria and fungi, ii) protists, iii) nematodes, iv) mesofauna (particularly spri…

Assessing the quality of dissolved organic matter in forest soils using ultraviolet absorption spectrophotometry

2007

Abbreviations: DOC, dissolved organic carbon; SUVA, specifi c ultraviolet absorbance; UV, ultraviolet. Ultraviolet spectrophotometry was used to investigate the effects, 30 yr after planting, of tree species substitution on the aromatic C content and related properties of dissolved organic carbon (DOC). Precautions were taken to correct measurements for the absorbance of NO 3 and dissolved Fe. In litter leachates, a signifi cant reduction in the aromatic content of DOC was found in the Douglas-fi r [Pseudotsuga menziesii (Mirb.) Franco] plantation but not in the beech (Fagus sylvatica L.) plantation. The disturbance of short-term C dynamics thus revealed agreed well with fi eld observations…

La terre : un bien hors du commun. De l'utopie à la révolution foncière

2018

International audience; La terre manque toujours cruellement d'un droit à sa démesure. Indispensable à la plupart des activités humaines, cette ressource naturelle est saisie par un ensemble disparate de règles au prix, trop souvent, d'une négation de ses qualités. « À vouloir "forcer" la terre, écrivait Pisani, nous prenons, en effet, le risque de la voir se dérober »2. De là, un mal bien terrestre de notre société, qui affecte aussi bien la chose elle-même que ses habitants. Les symptômes portent les noms d'accaparement, d'artificialisation, de surexploitation, de dégradation. Ils sont suffisamment graves pour justifier la création d'un authentique système foncier, projet politique encore…

LIFE CYCLE ASSESSMENT EXPERIENCES FOR SOLAR HEATING AND COOLING SYSTEMS

2018

Solar heating and cooling systems can significantly contribute to the energy and climate European goals. A complete assessment of this contribution needs the analysis of these systems from a life-cycle perspective, in order to estimate the energy and environmental costs of their manufacturing and end-of-life, and to compare these costs with the benefits obtained during operation. A well-established methodology to fulfil this task is the Life Cycle Assessment (LCA). The paper describes some LCA experiences of solar heating and cooling systems, developed within the Task 53 “New generation solar cooling & heating systems (PV or solar thermally driven systems)” of the International Energy A…

Résistances aux herbicides : au Nord, c’étaient les Laiterons !

2016

SPEGESTAD; Contexte - Après des échecs de désherbage de laiteron épineux à l’aide d’herbicides inhibiteurs de l’ALS (groupe HRAC B) en culture d’endives, l’hypothèse de la présence d’une résistance à ces herbicides a été étudiée. étude - Des tests biologiques avec un herbicide du groupe B (rimsulfuron) ont été effectués sur des populations provenant de parcelles « à problème ». Le gène de l’ALS a également été séquencé afin de rechercher la présence de mutations causant une résistance aux herbicides inhibiteurs de l’ALS dans ces populations. résultats - Les tests biologiques ont montré l’existence d’une résistance au rimsulfuron dans les trois parcelles étudiées. Des mutations au codon 197 …

Potential for adaptation to climate change: family-level variation in fitness-related traits and their responses to heat waves in a snail population.

2017

Background On-going global climate change poses a serious threat for natural populations unless they are able to evolutionarily adapt to changing environmental conditions (e.g. increasing average temperatures, occurrence of extreme weather events). A prerequisite for evolutionary change is within-population heritable genetic variation in traits subject to selection. In relation to climate change, mainly phenological traits as well as heat and desiccation resistance have been examined for such variation. Therefore, it is important to investigate adaptive potential under climate change conditions across a broader range of traits. This is especially true for life-history traits and defences ag…

Global urban environmental change drives adaptation in white clover

2022

Made available in DSpace on 2022-04-28T19:52:06Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-03-18 Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense that also affects tolerance to abiotic stressors. Urban-rural gradients were associated with the evolution of clines in defense in 47% of cities throughout the world. Variation in the strength of clines was explained by environmental changes in drought stress and vegetation cover that varied am…
